I. EXECUTIVE SUMMARY
This report presents the findings of the energy audit conducted for:
Entity: Bernards Public School
Facilities: Cedar Hill Elementary School Liberty Corner Elementary School Mount Prospect Elementary School Oak Street Elementary School Ridge High School William Annin Middle School District Contact Persons: Nick Markarian, Business Administrator Connie Coriell, Energy Efficiency Coordinator
Facility Contact Person: Artie Rivera, Head of Facilities
This audit is performed in connection with the New Jersey Clean Energy - Local Government Energy Audit Program for Bernards Public Schools facilities. The purpose of this analysis is to provide the district insight into the energy savings potential that exists within facilities at Bernards Public Schools. Energy Efficiency changes and upgrades requires support from the building occupants, operations personnel and the administrators of the district in order to maximize the savings and overall benefit. The efficiency improvement of public buildings provides a benefit for the environment and the residence of New Jersey. Through this report it has been demonstrated that there is a great potential for energy savings and infrastructure improvements at Bernards Public Schools. Fast Payback Energy Conservation Measures: The Energy Conservation Measures (ECMs) identified within the reports represent the potential annual savings at each facility. It is recommended to consider all ECMs as part of the school district’s initiative to save energy, reduce emissions, and lower operating costs. Several ECMs shown within this report represent significant savings relative to the cost to implement. The ECMs shown with a simple payback of 10 years and less are considered very cost effective and should be considered a high priority for the District. The following ECMs are highly recommended:
• Lighting Upgrades (All facilities) Lighting retrofits throughout the school district is a straight forward conservation measure that is prescriptive in nature and provides substantial savings for the investment. Lighting retrofits is a good example of ECMs that can be implemented with “in house” staff to reduce the installation cost and further reduce paybacks. The measure includes replacing existing 700 series T-8 fluorescent lamps with new higher efficiency T-8 lamps in all schools. This upgrade also
Bernards Public Schools Executive Energy Report
Concord Engineering Group, Inc. 9C10088 April 15, 2011– FINAL Page 4 of 35
includes installation of high bay T-5 fixtures to replace the existing metal halide fixtures. This provides additional energy savings for rooms such as the gymnasiums and auditoriums. In addition it is recommended to utilize CFL lamps in lieu of all existing incandescent lamps throughout the school district. Overall lighting upgrades represent one of the most easily implemented ECMs and are highly recommended for all facilities.
• Lighting Controls (All facilities) Similar to lighting upgrades, lighting controls are very simple upgrades and can save considerable energy. Lighting controls do not require replacement of the fixture and typically can save more energy than lighting upgrades alone. The maximum savings can be achieved through the implementation of both the lighting upgrades and lighting controls ECMs. Lighting controls will automatically turn off lights when spaces and rooms are not occupied. It is important to note that ECMs are calculated as stand-alone ECMs and therefore the total savings will be slightly less than the sum of both individual ECMs (Lighting Upgrade and Lighting Controls). The discrepancy between additive ECMs is within the tolerances for this level of analysis (+/- 20%). Lighting controls provide the maximum savings in spaces that have changing occupancy schedules throughout the day such as the classrooms after school hours, labs, music rooms, media centers, etc. Lighting controls is highly recommended in addition to the lighting upgrade ECMs for Bernards Public Schools.
• Computer Monitor Replacement (All facilities) Plug loads within buildings is becoming a larger and larger portion of the total energy use all types of facilities. Plug loads are most dominant in combination with computers and computer equipment. Modern computer monitors are flat screen LCD panels that are far more efficiency than older style cathode ray-tube (CRT) monitors. Typical energy use of a flat screen monitor is approximately 1/3 to 1/4 of the energy used by a CRT monitor. The majority of computer monitors throughout the district are CRT style monitors. This represents a significant energy savings potential. It is highly recommended to replace the existing CRT monitors with flat screen monitors to take advantage of the energy savings as well as other ergonomic benefits of modern LCD monitors.
• Hot Water Valve Blanket Insulation (Cedar Hill, Ridge, & William Annin) Hot Water piping insulation is a valuable asset to avoid the loss of heat from the boiler system. Large diameter bare steel pipe can account for significant energy loss over an entire heating season. Since the piping remains hot 24/7, bare pipe heat losses are multiplied by the entire operating hours of the heating system. Pipe & valve insulation reduces the loss compared to bare pipe by a factor of 10 or more. Pipe insulation becomes deteriorated overtime due to the repair of pipe / fitting leaks and service of components. Due to the savings from insulating the system to new condition, this ECM provides a payback within 10 years and is highly recommended.
• VFD HW Pumps (Ridge, William Annin)
Bernards Public Schools Executive Energy Report
Concord Engineering Group, Inc. 9C10088 April 15, 2011– FINAL Page 5 of 35
Large constant volume pumping systems require a lot of energy to operate continuously. Systems designed with 3-way control valves do not limit flow when demand for hot water is low. As a result pumping energy remains constant approximately equal to the rating of the pump motor. Variable Frequency Drives provides in combination with 2-way control at terminal devices provides a way to limit pump energy when the system demand is reduced. VFD drives install on larger pumping systems such as the high school and middle school provides the most advantageous paybacks. This ECM assumes retrofit of the existing 3-way control valves to operate as 2-way control valves. This conversion must be verified before implementation. Once the overall scope for the retrofit is determined, it is anticipated this ECM will provide a good payback for the district. Capital Improvement Energy Conservation Measures: The ECMs that have much longer paybacks are considered capital improvement ECMs. These ECMs typically have high installation costs that are more difficult to justify the savings based solely on the energy savings associated with the improvement. Despite the long paybacks, these ECMs in many cases provide valuable and much needed infrastructure improvements for the facility. These ECMs include boiler upgrades, HVAC equipment upgrades, motor replacements, controls upgrades, etc. The savings identified for the following ECMs provides additional incentive for the district’s capital improvement projects.
• Energy Recovery Unit Ventilators (Ridge, William Annin, & Mount Prospect) The existing unit ventilators throughout the newer sections of the schools are heated and cooled with vertical style units made by Airdale without energy recovery. These units can be easily replaced with new vertical style units with additional features options such as energy recovery. Due to the modular style of the Airdale units, this retrofit is more easily implemented. Energy recovery allows the units to provide outside air to the classrooms at about one fourth of the energy required to heat and cool the ventilation air. The installation of these new units provides energy savings as well as avoided cost of replacing the existing unit ventilators, which are close to the end of their rated life. This ECM only includes the replacement of the “Graduate” series units and does not include retrofit of the most recent unit ventilators within the 700 wing of Ridge High School. This ECM does not include retrofit of the existing horizontal cabinet unit ventilators made by Nesbitt. The original building unit ventilators throughout the schools are heating only units and not easily retrofitted to include energy recovery. The savings from the replacement of the old unit ventilators is very difficult to justify its replacement and therefore this ECM is limited to the vertical style heating and cooling unit ventilators throughout the district.
• AC Unit Upgrades (All Facilities except for Mount Prospect) High efficiency AC unit installations will typically have high installation costs. However, the savings over time can be substantial. The simple paybacks for AC units range between 25 yrs and 30 years depending on the existing equipment efficiency, runtime, and size / installation cost. Similar to most capital improvement projects, the energy savings alone does not justify the

Concord Engineering Group, Inc. 9C10088 April 15, 2011– FINAL Page 6 of 35
installation. The benefit of replacing the aging AC systems with new equipment provides value through avoided costs for School District that should not be overlooked.
• Condensing Boilers (All Facilities except for Mount Prospect & Oak Street) Condensing boiler replacements are one of the the most significant HVAC system upgrade for a facility. The installation of condensing boilers provides a heating efficiency increase ranging from 10% to 15%. The simple payback for condensing boiler ECMs range from 45 to 62 years depending on the boiler capacity and installation difficulty. These ECMs represent the most substantial upfront cost which creates long paybacks. They also represent significant infrastructure improvements throughout the District.
• Premium Motor Replacements (All Facilities except for Oak Street) The simple payback for premium efficiency motor replacements ranges from 15 to 25 years depending on the horse power, existing efficiency, and run hours of the equipment. This ECM is a one-for-one style replacement with dependable savings that is based on a simple calculation. In addition to the savings, this ECM provides new motors for a variety of existing equipment.
• Kitchen Hood Controls (Ridge & Liberty Corner) Kitchen hood controls allows the exhaust air through the commercial kitchen hood to reduce with respect to the level of heat and smoke produced by the kitchen cooking equipment. This approach automatically slows the hood exhaust and make-up air to minimum levels at light or non use conditions. This ECM provides saving on fan motors as well as energy required to heat and cool the make-up air exhausted by the hood. The savings are extremely dependent on the operating hours of the kitchen hood exhaust fan. Based on the survey and discussions with the operating staff, it was determined that several schools minimize the use of the kitchen hood through the manual switch. In other schools such as Ridge and Liberty Corner, it was noted that the kitchen exhaust was operating for many hours beyond the needs of the cooking equipment. The payback range for this ECM can vary greatly based on the operating hours. Ridge provides a payback within 10 years while Liberty Corner has a simple payback of 28 years. It is recommended to review the operating hours of the kitchen exhaust fan for all schools and refine the savings as a result. At a minimum a district wide hood operation schedule should be implemented for the use of the kitchen hood exhaust to limit over ventilation when it is not needed.
• Kitchen Domestic Booster Heater (Ridge, William Annin) Large schools including Ridge High School and William Annin Middle School require significant hot water for cleaning and sterilization of the kitchen dishes and serving trays. Commercial kitchen dishwashing equipment requires hot water at sterilization temperatures far above the buildings typical domestic hot water supply. The dishwasher utilizes a large capacity electric booster heater to boost the domestic hot water to the adequate temperature. The proposed installation utilizes a natural gas hot water heater in lieu of the existing electric booster heater. The savings are based on switching fuels from electric to natural gas. The simple payback of this
Bernards Public Schools Executive Energy Report
Concord Engineering Group, Inc. 9C10088 April 15, 2011– FINAL Page 7 of 35
ECM is approximately 13 years based on a dishwasher run time of 1 hour per day. One hour per day is a conservative estimate to show realistic savings. If additional runtime is calculated on the kitchen dishwashing equipment, the savings would increase respectively. Combined Project Approach: Although only individual projects with a simple payback of 10 years and less are considered financially self sustaining, it is important to consider how multiple projects can be combined together. When ECMs are aggregated into a single project, the lower cost ECMs provides valuable savings to offset the higher cost ECMs. Likewise when multiple facilities are aggregated together into a single entity energy efficiency project, the same benefits are seen on a larger scale. The Energy Savings Improvement Program (ESIP) allows for financing of any combination of energy efficiency projects across multiple facilities into one large project. The term of the financing must be under 15 years and the savings provides the revenue for the financing cost. The combination of all facilities into one large energy efficiency project provides Bernards Public Schools with the opportunity to implement a large portion of the ECMs identified with an overall simple payback of 11.2 years. Any ECMs not included in the total project summary are highlighted within the individual facility reports. This combined option allows the Bernards Public Schools to implement much needed infrastructure improvements such as new air conditioning equipment, motors, lighting, lighting controls, and etc. The program financing allows for the implementation with no upfront cost for district. Implementation of an ESIP provides significant benefits and should be strongly considered. The total Entity Project Summary table below shows the savings, costs, incentives and paybacks for all ECMs at Bernards Public Schools.

Implementation of all ECMs identified within the ESIP – Entity Total Project Summary table represents a total annual savings of approximately $242,099 for the district. The individual facility project summaries are shown within each facility energy audit report. The ESIP program allows for a maximum financing term of 15 years. Based on the project costs and savings identified above, there is the potential for re-arranging the ECMs into a scope of work that includes the Condensing Boilers, which could be a large future capital cost for the district. This would allow the new boilers to be installed through the ESIP program in lieu of the district financing the improvements with other means. Further review through the development of an Energy Savings Plan (ESP) is needed to verify all potential options.

Other Considerations:
• Maintenance and Operational Measures In addition to the ECMs, there are maintenance and operational measures that can provide energy savings and provide immediate benefit. The ECMs listed above represent investments that can be made to the facility which are justified by the savings seen overtime. However, the maintenance items and small operational improvements below are typically achievable with on site staff or maintenance contractors and in turn have the potential to provide on operational costs. The following are recommendations which should be considered a priority when moving forward with energy efficiency upgrades:
1. Chemically clean the condenser and evaporator coils periodically to optimize efficiency.
Poorly maintained heat transfer surfaces can reduce efficiency 5-10%. 2. Maintain all weather stripping on entrance doors to limit unnecessary infiltration. 3. Clean all light fixtures to maximize light output to provide better light output and avoid the
use of task lighting where otherwise not necessary. 4. Provide more frequent air filter changes to decrease overall system power usage and maintain
better IAQ. 5. Verify proper operation of all outside air dampers throughout the school district. Older
equipment may have ventilation dampers that are either stuck open or shut, either contributing to excessive energy use or poor indoor air quality. Outside air damper measurements are also extremely valuable when verifying the potential energy savings for energy recovery and demand control ventilation ECMs.
6. Inspect the vertical style unit ventilators to be air tight with the outside air connection to the exterior wall louver. It was noted during the survey that cold air was leaking into the unit cabinet due to poor connection with the outside air louver. Leakage of cold outside air can account for unnecessary energy use as well as create the potential for freezing piping.
• Renewable Energy Measures
Renewable Energy Measures (REMs) were also reviewed for implementation at Bernards Public Schools. CEG utilized a combination of roof mounted solar arrays and canopy style parking lot solar arrays to house PV systems throughout Bernards Public Schools buildings. The total solar electric production potential for these systems is approximately 1,540,128 kWh, which would reduce the district’s electric grid purchased electric energy by 22%. The system’s calculated simple payback of approximately 15 years is past the standard 10 year simple payback threshold; however, with alternative funding this payback could be lessened. CEG recommends the Owner review all funding options available with the implementation of this renewable energy measure.
• System Controls The information provided by the operations and maintenance personnel identified various control systems installed at the school district. In addition multiple control system contractors are utilized to maintain the various control systems. It was noted that in many cases the existing
Bernards Public Schools Executive Energy Report
Concord Engineering Group, Inc. 9C10088 April 15, 2011– FINAL Page 10 of 35
control are not functioning correctly resulting in poor control of the building space temperatures. In some instances such as Ridge High School and William Annin Middle School, windows were opened in the winter in order to cool rooms that were significantly overheated by the lack of control of the system. The detailed information regarding the control system status, set points, schedules and operation was not available, however it is evident that the interrelation of multiple control systems and lack of direct access to its functions, negatively affects the building’s operations and ability for the staff to maintain and correct HVAC issues. Controls issues are often difficult to identify and pinpoint the fault or device malfunctioning. Retro Commissioning provides a method to test and re-establish building systems back to their correct operation. In many cases Retro-Commissioning alone has show to reduce heating and cooling energy costs by 15% by correcting items identified through the commissioning process. For future project planning, it is important to consider commissioning as a means to verify that the intent of the energy efficiency upgrade is accomplished and savings will be achieved. Commissioning is highly recommended for all aspects of energy efficiency upgrades including equipment upgrades as well as control system upgrades. Ensuring that schedules, set points, and adjustability is programmed correctly is vital with a new control system upgrade. Overall Assessment: Overall, Bernards Public Schools are maintained and operating fairly efficiently with room for improvement. There are numerous ECMs that can be implemented to further reduce energy use and save on the facility’s operating costs. The total energy cost of $1,586,265 could be reduced by approximately 15.3% through the implementation of the ECMs recommended in the combined project approach summary table. Bernards Public Schools is in a beneficial position to implement energy efficiency improvements and still include large capital projects. When the total project is capable of being funded through the savings, CEG highly recommends the school district to take advantage of this opportunity.

II. INTRODUCTION The comprehensive energy audit covers the following facilities at Bernards Public Schools:
• Cedar Hill Elementary School • Liberty Corner Elementary School • Mount Prospect Elementary School • Oak Street Elementary School • Ridge High School • William Annin Middle School
This audit is performed in connection with the New Jersey Clean Energy - Local Government Energy Audit Program. The energy audit is conducted to promote the mission of the office of Clean Energy, which is to use innovation and technology to solve energy and environmental problems in a way that improves the State’s economy. This can be achieved through the wiser and more efficient use of energy. Electrical and natural gas utility information is collected and analyzed for one full year’s energy use of each building. The utility information allows for analysis of the building’s operational characteristics; calculate energy benchmarks for comparison to industry averages, estimated savings potential, and baseline usage/cost to monitor the effectiveness of implemented measures. A computer spreadsheet is used to calculate benchmarks and to graph utility information (see the utility profiles below). The Energy Use Index (EUI) is established for the building. Energy Use Index (EUI) is expressed in British Thermal Units/square foot/year (BTU/ft2/yr), which is used to compare energy consumption to similar building types or to track consumption from year to year in the same building. The EUI is calculated by converting the annual consumption of all energy sources to BTU’s and dividing by the area (gross square footage) of the building. Blueprints (where available) are utilized to verify the gross area of the facility. The EUI is a good indicator of the relative potential for energy savings. A low EUI indicates less potential for energy savings, while a high EUI indicates poor building performance therefore a high potential for energy savings. Existing building architectural and engineering drawings (where available) are utilized for additional background information. The building envelope, lighting systems, HVAC equipment, and controls information gathered from building drawings allow for a more accurate and detailed review of the building. The information is compared to the energy usage profiles developed from utility data. Through the review of the architectural and engineering drawings a building profile can be defined that documents building age, type, usage, major energy consuming equipment or systems, etc. The preliminary audit information is gathered in preparation for the site survey. The site survey provides critical information in deciphering where energy is spent and opportunities exist within a facility. The entire site is surveyed to inventory the following to gain an understanding of how each facility operates:
Bernards Public Schools Executive Energy Report
Concord Engineering Group, Inc. 9C10088 April 15, 2011– FINAL Page 12 of 35
• Building envelope (roof, windows, etc.) • Heating, ventilation, and air conditioning equipment (HVAC) • Lighting systems and controls • Facility-specific equipment
The building site visit is performed to survey all major building components and systems. The site visit includes detailed inspection of energy consuming components. Summary of building occupancy schedules, operating and maintenance practices, and energy management programs provided by the building manager are collected along with the system and components to determine a more accurate impact on energy consumption.

III. METHOD OF ANALYSIS
This audit is consistent with an ASHRAE level 2 audit. The cost and savings for each measure is ± 20%. The evaluations are based on engineering estimations and industry standard calculation methods. More detailed analyses would require engineering simulation models, hard equipment specifications, and contractor bid pricing. Post site visit work includes evaluation of the information gathered, researching possible conservation opportunities, organizing the audit into a comprehensive report, and making recommendations on HVAC, lighting and building envelope improvements. Data collected is processed using energy engineering calculations to anticipate energy usage for each of the proposed energy conservation measures (ECMs). The actual building’s energy usage is entered directly from the utility bills provided by the owner. The anticipated energy usage is compared to the historical data to determine energy savings for the proposed ECMs. It is pertinent to note, that the savings noted in this report are not additive. The savings for each recommendation is calculated as standalone energy conservation measures. Implementation of more than one ECM may in some cases affect the savings of each ECM. The savings may in some cases be relatively higher if an individual ECM is implemented in lieu of multiple recommended ECMs. For example implementing reduced operating schedules for inefficient lighting will result in a greater relative savings. Implementing reduced operating schedules for newly installed efficient lighting will result in a lower relative savings, because there is less energy to be saved. The project / Entity summary tables are based on the implementation of multiple measures. The analysis is reviewed and determined if the nature of the ECMs will cause a major conflict of the overall savings. When additive measures do not cause a major effect on the overall savings the ECMs are included. Where a major conflict is identified, the combined savings is evaluated appropriately to ensure the overall estimates are ± 20%. ECMs are determined by identifying the building’s unique properties and deciphering the most beneficial energy saving measures available that meet the specific needs of the facility. The building construction type, function, operational schedule, existing conditions, and foreseen future plans are critical in the evaluation and final recommendations. Energy savings are calculated base on industry standard methods and engineering estimations. Energy consumption is calculated based on manufacturer’s cataloged information when new equipment is proposed. Cost savings are calculated based on the actual historical energy costs for the facility. Installation costs include labor and equipment costs to estimate the full up-front investment required to implement a change. Costs are derived from Means Cost Data, industry publications, and local contractors and equipment suppliers. The NJ Smart Start Building® program incentives savings (where applicable) are included for the appropriate ECM’s and subtracted from the installed cost. Maintenance savings are calculated where applicable and added to the energy savings for each ECM. The life-time for each ECM is estimated based on the typical life of the equipment being replaced or altered. The costs and savings are applied and a simple payback, simple lifetime savings, and simple return on investment are calculated. See below for calculation methods:

B. Energy Use Index (EUI) Energy Use Index (EUI) is a measure of a building’s annual energy utilization per square foot of building. This calculation is completed by converting all utility usage consumed by a building for one year, to British Thermal Units (BTU) and dividing this number by the building square footage. EUI is a good measure of a building’s energy use and is utilized regularly for comparison of energy performance for similar building types. The Oak Ridge National Laboratory (ORNL) Buildings Technology Center under a contract with the U.S. Department of Energy maintains a Benchmarking Building Energy Performance Program. The ORNL website determines how a building’s energy use compares with similar facilities throughout the U.S. and in a specific region or state. Source use differs from site usage when comparing a building’s energy consumption with the national average. Site energy use is the energy consumed by the building at the building site only. Source energy use includes the site energy use as well as all of the losses to create and distribute the energy to the building. Source energy represents the total amount of raw fuel that is required to operate the building. It incorporates all transmission, delivery, and production losses, which allows for a complete assessment of energy efficiency in a building. The type of utility purchased has a substantial impact on the source energy use of a building. The EPA has determined that source energy is the most comparable unit for evaluation purposes and overall global impact. Both the site and source EUI ratings for the building are provided to understand and compare the differences in energy use. The site and source EUI for this facility is calculated as follows:

C. EPA Energy Benchmarking System The United States Environmental Protection Agency (EPA) in an effort to promote energy management has created a system for benchmarking energy use amongst various end users. The benchmarking tool utilized for this analysis is entitled Portfolio Manager. The Portfolio Manager tool allows tracking and assessment of energy consumption via the template forms located on the ENERGY STAR website (www.energystar.gov). The importance of benchmarking for local government municipalities is becoming more important as utility costs continue to increase and emphasis is being placed on carbon reduction, greenhouse gas emissions and other environmental impacts. Based on information gathered from the ENERGY STAR website, Government agencies spend more than $10 billion a year on energy to provide public services and meet constituent needs. Furthermore, energy use in commercial buildings and industrial facilities is responsible for more than 50 percent of U.S. carbon dioxide emissions. It is vital that local government municipalities assess facility energy usage, benchmark energy usage utilizing Portfolio Manager, set priorities and goals to lessen energy usage and move forward with priorities and goals. The ENERGY STAR account for the school district was created by the school district. This account allows for access and monitoring the facility’s yearly energy usage as it compares to facilities of similar type. The login page for the account can be accessed at the following web address; the username and password are also listed below:

V. RENEWABLE/DISTRIBUTED ENERGY MEASURES Globally, renewable energy has become a priority affecting international and domestic energy policy. The State of New Jersey has taken a proactive approach, and has recently adopted in its Energy Master Plan a goal of 30% renewable energy by 2020. To help reach this goal New Jersey created the Office of Clean Energy under the direction of the Board of Public Utilities and instituted a Renewable Energy Incentive Program to provide additional funding to private and public entities for installing qualified renewable technologies. A renewable energy source can greatly reduce a building’s operating expenses while producing clean environmentally friendly energy. CEG has assessed the feasibility of installing renewable energy measures (REM) for the municipality utilizing renewable technologies and concluded that there is potential for solar energy generation. Solar Generation Solar energy produces clean energy and reduces a building’s carbon footprint. This is accomplished via photovoltaic panels which are mounted on all south and southwestern facades of the building. Flat roof, as well as sloped areas can be utilized; flat areas will have the panels turned to an optimum solar absorbing angle. (A structural survey of the roof would be necessary before the installation of PV panels is considered). Parking lots can also be utilized for the installation of a solar array. A truss system can be installed that is high enough to park vehicles under the array and no parking lot area is lost. The state of NJ has instituted a program in which one Solar Renewable Energy Certificate (SREC) is given to the Owner for every 1000 kWh of generation. SREC’s can be sold anytime on the market at their current market value. The value of the credit varies upon the current need of the power companies. The average value per credit is around $350, this value was used in our financial calculations. This equates to $0.35 per kWh generated. CEG has reviewed the existing roof area and parking lot canopy area potential of the remaining facilities being audited for the purposes of determining a potential for a photovoltaic system. The facilities with structural deficiencies were not considered for a roof mounted system. Instead where applicable a parking lot canopy system was reviewed. A depiction of the area utilized at each facility is shown in Renewable / Distributed Energy Measures Calculation Appendix. The system sizes are shown below for each building where installation of a solar PV system is feasible. The total KWH production for all facilities combined is 1,540,128 kWh annually, reducing the overall utility bill for the district by approximately 22% percent.. A detailed financial analysis can be found in the Renewable / Distributed Energy Measures Calculation Appendix within each facility report. This analysis illustrates the payback of the system over a 25 year period. The eventual degradation of the solar panels and the price of accumulated SREC’s are factored into the payback.

POWER PRODUCTION SUMMARY - PHOTOVOLTAIC SYSTEM PER FACILITY
FACILITY PRODUCTION SUMMARY
The proposed photovoltaic array layout is designed based on the specifications for the Sun Power SPR-230 panel. This panel has a “DC” rated full load output of 230 watts, and has a total panel conversion efficiency of 18%. Although panels rated at higher wattages are available through Sun Power and other various manufacturers, in general most manufacturers who produce commercially available solar panels produce a similar panel in the 200 to 250 watt range. This provides more manufacturer options to the public entity if they wish to pursue the proposed solar recommendation without losing significant system capacity. The array system capacity was sized based on available roof space or canopy style system area available at each existing facility. Estimated solar array generation is calculated based on the National Renewable Energy Laboratory PVWatts Version 1.0 Calculator. In order to calculate the array generation an appropriate location with solar data on file must be selected. In addition the system DC rated kilowatt (kW) capacity must be inputted, a DC to AC de-rate factor, panel tilt angle, and array azimuth angle. The DC to AC de-rate factor is based on the panel nameplate DC rating, inverter and transformer efficiencies (95%), mismatch factor (98%), diodes and connections (100%), dc and ac wiring(98%, 99%), soiling, (95%), system availability (95%), shading (if applicable), and age(new/100%). The overall DC to AC de-rate factor has been calculated at an overall rating of 81%. The PVWatts Calculator program then calculates estimated system generation based on average monthly solar irradiance and user provided inputs.

Concord Engineering Group, Inc. 9C10088 April 15, 2011– FINAL Page 24 of 35
The monthly energy generation and offset electric costs from the PVWatts calculator is shown in the Renewable/Distributed Energy Measures Calculation Appendix. The proposed solar array for each facility is qualified by the New Jersey Board of Public Utilities Net Metering Guidelines as a Class I Renewable Energy Source. These guidelines allow onsite customer generation using renewable energy sources such as solar and wind with a capacity of 2 megawatts (MW) or less. This limits a customer system design capacity to being a net user and not a net generator of electricity on an annual basis. Although these guidelines state that if a customer does net generate (produce more electricity than they use), the customer will be credited those kilowatt-hours generated to be carried over for future usage on a month to month basis. Then, on an annual basis if the customer is a net generator the customer will then be compensated by the utility the average annual PJM Grid LMP price per kilowatt-hour for the over generation. Due to the aforementioned legislation, the customer is at limited risk if they generate more than they use at times throughout the year. With the inefficiency of today’s energy storage systems, such as batteries, the added cost of storage systems is not warranted and was not considered in the proposed design. Direct purchase involves the district paying for 100% of the total project cost upfront via one of the methods noted in the Installation Funding Options section below. Calculations include a utility inflation rate as well as the degradation of the solar panels over time. The financial summary per facility is as follows:

FINANCIAL SUMMARY - PHOTOVOLTAIC SYSTEM PER FACILITY
FACILITY DIRECT PURCHASE FINANCIAL SUMMARY
CEG recommends the district review all options available for installation of solar PV systems at their facilities including a Power Purchase Agreement (PPA). This option utilizes providers who will own, operate, and maintain the system for a period of 15 years. During this time the PPA Provider would sell all of the electric generated by the Solar Arrays to the school district at a reduced rate compared to their existing electric rate. Wind Generation In addition to the Solar Analysis, CEG also conducted a review of the applicability of wind energy for the facility. Wind energy production is another option available through the Renewable Energy Incentive Program. Wind turbines of various types can be utilized to produce clean energy on a per building basis. Cash incentives are available per kWh of electric usage. Based on CEG’s review of the applicability of wind energy for the facility, it was determined that the average wind speed of <4.5 m/s is not adequate for purchase of a commercial wind turbine. Therefore, wind energy is not a viable option to implement.

VI. ENERGY PURCHASING AND PROCUREMENT STRATEGY Load Profile: Load Profile analysis was performed to determine the seasonal energy usage of the facility. Irregularities in the load profile will indicate potential problems within the facility. Consequently based on the profile a recommendation will be made to remedy the irregularity in energy usage. For this report, the facility’s energy consumption data was gathered in table format and plotted in graph form to create the load profile. Refer to The Electric and Natural Gas Usage Profiles included within this report to reference the respective electricity and natural gas usage load profiles. Electricity: The electricity usage profile demonstrates a steady year long load profile for school facilities that have occupancy during the summer months. Largest consumption months were December, January, June and August. The historical usage profile is beneficial and will allow for more competitive energy prices when shopping for alternative suppliers mainly due to the relatively flat load profile. Third Party Supplier (TPS) electric commodity contracts that offer’s a firm, fixed price for 100% of the facilities electric requirements and are lower than the JCP&L’s BGS-FP default rate are recommended. Natural Gas: The Natural Gas Usage Profile demonstrates a very typical natural gas (heat load) profile for school buildings. The summer months June – August have very little consumption. This load profile will yield less favorable natural gas pricing when shopping for alternative suppliers. This is because the higher winter month consumption will yield higher pricing which will not be offset by the summer month consumption. Nymex commodity pricing is generally higher in the winter months of November – March and lower in the summer months of April – October. Obtaining a flat load profile, (usage is similar each month), will yield optimum natural gas pricing when shopping for alternative suppliers. Third Party Supplier (TPS) natural gas commodity contracts that offer a product structures that offer either 1) a fixed basis rate with a market based Nymex/commodity rate or 2) a fixed basis rate with fixed Nymex/commodity winter rate (Nov – March) and market based Nymex/commodity rate for the summer months (April – October) for 100% of the facilities metered natural gas requirements are both recommended due to current market pricing.

Concord Engineering Group, Inc. 9C10088 April 15, 2011– FINAL Page 27 of 35
Tariff Analysis: Electricity: The school facilities receive electrical service through Jersey Central Power & Light (JCP&L) on a GS-Sec (General Service Secondary) rate and are master account billed which eliminates individual customer service charges. The facilities have contracted a Third Party Supplier (TPS) to provide electric commodity service on a fixed price through South Jersey Energy as of May 2009. The current electric supply contract expires May 2012. For electric supply (generation) service, the client has a choice to either use JCP&L’s default service rate BGS-FP or contract with a Third Party Supplier (TPS) to supply electric. Each year since 2002, the four New Jersey Electric Distribution Companies (EDCs) - Public Service Gas & Electric Company (PSE&G), Atlantic City Electric Company (ACE), Jersey Central Power & Light Company (JCP&L), and Rockland Electric Company (RECO) - have procured several billion dollars of electric supply to serve their Basic Generation Service (BGS) customers through a statewide auction process held in February. BGS refers to the service of customers who are not served by a third party supplier or competitive retailer. This service is sometimes known as Standard Offer Service, Default Service, or Provider of Last Resort Service. The Auction Process has consisted of two auctions that are held concurrently, one for larger customers on an hourly price plan (BGS-CIEP) and one for smaller commercial and residential customers on a fixed-price plan (BGS-FP). This facility’s rate structure is based on the fixed-price plan (BGS-FP). The facility’s current BGS-FP average price to compare for GS-Secondary rate is $0.1190/kWh. The utility, JCP&L will continue to be responsible for maintaining the existing network of wires, pipes and poles that make up the delivery system, which will serve all consumers, regardless of whom they choose to purchase their electricity or natural gas from. JCP&L’s Delivery Service rate includes the following charges: Customer Charge, Supplemental Customer Charge, Distribution Charge (kW Demand), kWh Charge, Non-utility Generation Charge, TEFA, SBC, SCC, Standby Fee and RGGI. Natural Gas: This facility currently receives natural gas distribution service through Public Service Electric and Gas Company (PSE&G) on rate schedules Large Volume Service (LVG) and General Service Gas (GSG) and has contracted a Third Party Supplier (TPS) to provide natural gas commodity service on a fixed basis rate plus market based commodity through Woodruff Energy. The current natural gas contract expires July 2011.

Concord Engineering Group, Inc. 9C10088 April 15, 2011– FINAL Page 28 of 35
PSE&G provides basic gas supply service (BGSS) to customers who choose not to shop from a Third Party Supplier (TPS) for natural gas commodity. The option is essential to protect the reliability of service to consumers as well as protecting consumers if a third party supplier defaults or fails to provide commodity service. Please refer to the link below for a recap of natural gas BGSS charges from PSE&G for rate schedule LVG and GSG. http://www.pseg.com/companies/pseandg/schedules/pdf/commodity.pdf The utility, PSE&G is responsible for maintaining the existing network of wires, pipes and poles that make up the delivery system, which will serve all consumers, regardless of whom they choose to purchase their electricity or natural gas from. PSE&G’s delivery service rate includes the following charges: Customer Service Charge, Distribution Charge, & Societal Benefits Charge (SBC).
Electric and Natural Gas Commodities Market Overview:
Current electricity and natural gas market pricing has remained relatively stable over the last year. Commodity pricing in 2008 marked historical highs in both natural gas and electricity commodity. Commodity pricing commencing spring of 2009 continuing through 2010, has decreased dramatically over 2008 historic highs and continues to be favorable for locking in long term (2-5 year) contracts with 3rd Party Supplier’s for both natural gas and electricity supply requirements.
It is important to note that both natural gas and electric commodity market prices are moved by supply and demand, political conditions, market technicals and trader sentiment. This market is continuously changing Energy commodity pricing is also correlated to weather forecasts. Because weather forecasts are dependable only in the short-term, prolonged temperature extremes can really cause extreme price swings.

Short Term Energy Outlook - US Energy Information Administration (1/11/2011):
U.S. Natural Gas Prices. The Henry Hub spot price averaged $4.25 per MMBtu during December, an increase of about 54 cents from November's price of $3.71 per MMBtu. EIA expects the higher forecast production during the first half of 2011 compared with the same period last year, combined with a decline in consumption, to moderate natural gas spot prices. The projected spot price falls to a low of $3.73 per MMBtu in June then rises to $4.61 in December, averaging $4.02 per MMBtu for all of 2011, which is $0.37 per MMBtu lower than the 2010 average and $0.31 per MMBtu lower than in last month's Outlook. In 2012, the spot price rises to an average of $4.50 per MMBtu.
Uncertainty over future natural gas prices is slightly lower this year compared with last year at this time. Natural gas futures for March 2011 delivery (for the 5-day period ending January 6) averaged $4.39 per MMBtu, and the average implied volatility over the same period was 43 percent. This produced lower and upper bounds for the 95-percent confidence interval for March 2011 contracts of $3.21 per MMBtu and $6.02 per MMBtu, respectively. At this time last year, the natural gas March 2010 futures contract averaged $5.73 per MMBtu and implied volatility averaged 57 percent. The corresponding lower and upper limits of the 95-percent confidence interval were $3.88 per MMBtu and $8.47 per MMBtu.
U.S. Electricity Retail Prices. EIA expects the U.S. retail price for electricity distributed to the residential sector during 2010 to average 11.6 cents per kilowatt-hour, about the same level as in 2009. EIA expects the U.S. residential price to increase only slightly over the forecast period--by 0.6 percent in 2011 and by 1.0 percent in 2012.

Recommendations:
1. CEG recommends a continued aggregated approach for 3rd party commodity supply procurement strategies for electric and natural gas supply service. Aggregating the usage of all school facilities for electricity and natural gas supply service, would allow the facilities to achieve a reduction in commodity supply costs. Energy commodities are among the most volatile of all commodities, however at this point and time, energy is extremely competitive. Contracts due to expire in the near term would yield more favorable pricing than previously realized. It is important to aggregate usage where available and take advantage of these current market prices quickly, before energy increases.
Overall, after review of the utility consumption, billing, and current commodity pricing outlook, CEG recommends that the school facilities continue to participate in the existing energy supply aggregation groups (ACES & Middlesex Regional). Both aggregation groups utilize the advisement of 3rd party unbiased Energy Consulting Firm experienced in the aggregation of and procurement of retail electricity and natural gas commodity. It is important to note that the Energy Consulting Firm should incorporate a rational, defensible strategy for purchasing commodity in volatile markets based upon the following:
• Budgets that reflect sound market intelligence • An understanding of historical prices and trends • Awareness of seasonal opportunities (e.g. shoulder months) • Negotiation of fair contractual terms • An aggressive, market based price
Recent legislation recommends school districts participate in an approved NJ cooperative purchasing program for the purchase of energy commodities. Current cooperative pricing energy supply systems can be found at: http://www.nj.gov/dca/lgs/lpcl/power_coops_list.pdf.
2. CEG recommends that the school district consider utilizing a third party utility billing-
auditing service to further analyze historical utility invoices such as water, sewer, natural gas and electric for incorrect billings and rate tariff optimization services. This service can be based on a shared savings model with no cost to the school district. The service could provide refunds on potential incorrect billings that may have been passed through by the utilities and paid by the school.

VII. INSTALLATION FUNDING OPTIONS CEG has reviewed various funding options for the facility owner to utilize in subsidizing the costs for installing the energy conservation measures noted within this report. Below are a few alternative funding methods: A. Incentive Programs: Pay For Performance The New Jersey Smart Start Pay for Performance program includes incentives based on savings resulted from implemented ECMs. The program is available for all buildings that were audited as part of the NJ Clean Energy’s Local Government Energy Audit Program. The facility’s participation in the program is assisted by an approved program partner. An “Energy Reduction Plan” is created with the facility and approved partner to shown at least 15% reduction in the building’s current energy use. Multiple energy conservation measures implemented together are applicable toward the total savings of at least 15%. No more than 50% of the total energy savings can result from lighting upgrades / changes.
Total incentive is capped at 50% of the project cost. The program savings is broken down into three benchmarks; Energy Reduction Plan, Project Implementation, and Measurement and Verification. Each step provides additional incentives as the energy reduction project continues. The benchmark incentives are as follows:
1. Energy Reduction Plan – Upon completion of an energy reduction
plan by an approved program partner, the incentive will grant $0.10 per square foot between $5,000 and $50,000, and not to exceed 50% of the facility’s annual energy expense. (Benchmark #1 is not provided in addition to the local government energy audit program incentive.)
2. Project Implementation – Upon installation of the recommended measures along with the “Substantial Completion Construction Report,” the incentive will grant savings per KWH or Therm based on the program’s rates. Minimum saving must be 15%. (Example $0.11 / kWh for 15% savings, $0.12/ kWh for 17% savings, … and $1.10 / Therm for 15% savings, $1.20 / Therm for 17% saving, …) Increased incentives result from projected savings above 15%.
3. Measurement and Verification – Upon verification 12 months after implementation of all recommended measures, that actual savings have been achieved, based on a completed verification report, the incentive will grant additional savings per kWh or Therm based on the program’s rates. Minimum savings must be 15%. (Example $0.07 / kWh for 15% savings, $0.08/ kWh for 17% savings, … and
Bernards Public Schools Executive Energy Report
Concord Engineering Group, Inc. 9C10088 April 15, 2011– FINAL Page 32 of 35
$0.70 / Therm for 15% savings, $0.80 / Therm for 17% saving, …) Increased incentives result from verified savings above 15%.
The following facilities are potential candidates for Pay for Performance:
• Cedar Hill Elementary School • Liberty Corner Elementary School • Mount Prospect Elementary School • Oak Street Elementary School • William Annin Middle School
Direct Install Program The New Jersey Clean Energy’s Direct Install Program is a state funded program that targets small commercial and industrial facilities with peak demand of less than 100 kW. This turnkey program is aimed at providing owners a seamless, comprehensive process for analysis, equipment replacement and financial incentives to reduce consumption, lower utility costs and improve profitability. The program covers up to 60% of the cost for eligible upgrades including lighting, lighting controls, refrigeration, HVAC, motors, variable speed drives, natural gas and food service. Participating contractors (refer to www.njcleanenergy.com) conduct energy assessments in addition to your standard local government energy audit and install the cost-effective measures. The following measures are potential candidates for Direct Install:
• Lighting Upgrade – All Facilities (High Bay Lighting & CFL Lighting) • Lighting Controls – All Facilities • AC Unit upgrades – All Facilities (15 Tons and under) • Premium Efficiency Motors – All Facilities (10 HP and under) • Demand Control Ventilation – (All Facilities)
Smart Start Program
Prescriptive Measures - The New Jersey Clean Energy’s Smart Start prescriptive measures incentives include unit pricing incentives for installation of energy efficient equipment and controls. Proposed equipment and controls must meet the minimum efficiency requirements as well as other application requirements. The Smart Start prescriptive incentives applicable for new construction, renovations, remodeling and equipment replacements, for a wide range of equipment including:
• Electric Chillers • Gas Cooling • Electric Unitary HVAC • Ground Source Heat Pumps • Gas Heating • Variable Frequency Drives • Gas Water Heating
Bernards Public Schools Executive Energy Report
Concord Engineering Group, Inc. 9C10088 April 15, 2011– FINAL Page 33 of 35
• Premium Motors • Prescriptive Lighting • Lighting Controls • Technical Studies
Custom Measures - The New Jersey Clean Energy’s Smart Start prescriptive measures incentives include all measures not identified in the prescriptive measures category or measures that must have savings verified through additional analysis such as energy model simulations. Custom measures are intended to include savings as a result of unique energy efficiency measures, which are typically facility specific such as waste heat recovery. Custom incentives are provided based on the amount of energy saved and minimum internal rate of return in order to be eligible.
Energy Efficiency and Conservation Block Grants The EECGB rebate provides supplemental funding up to $50,000 for counties and local government entities to implement energy conservation measures. The EECGB funding is provided through the American Recovery and Reinvestment Act (ARRA). The local government must be among the eligible local government entities listed on the NJ Clean Energy website as follows - http://njcleanenergy.com/commercial-industrial/programs/eecbg-eligible-entities. This program is limited to municipalities and counties that have not already received grants directly through the US department of Energy. Bernards Public Schools is not eligible directly for this grant however, Bernards Twp is eligible, and has the option to pass along funding to school districts at their discretion. If Bernards Public Schools can acquire EECBG or other ARRA funding through the district, then maximum KW limit for the Direct Install program is waived. It is recommended to look into an agreement with the township to see if utilizing this funding is an option.
CEG recommends the Owner review the use of the above-listed incentive options in addition to utilizing their standard method of financing for facilities upgrades in order to fund the proposed energy conservation measures.

B. Financing Options: Municipal Bonds Municipal bonds are a bond issued by a city or other local government, or their agencies. Potential issuers of municipal bonds include cities, counties, redevelopment agencies, school districts, publicly owned airports and seaports, and any other governmental entity (or group of governments) below the state level. Municipal bonds may be general obligations of the issuer or secured by specified revenues. Interest income received by holders of municipal bonds is often exempt from the federal income tax and from the income tax of the state in which they are issued, although municipal bonds issued for certain purposes may not be tax exempt. Power Purchase Agreement Public Law 2008, Chapter 3 authorizes contracts of up to fifteen (15) years for energy purchase contracts commonly known as “power purchase agreements.” These are programs where the contracting unit (Owner) procures a contract for, in most cases, a third party to install, maintain, and own a renewable energy system. These renewable energy systems are typically solar panels, windmills or other systems that create renewable energy. In exchange for the third party’s work of installing, maintaining and owning the renewable energy system, the contracting unit (Owner) agrees to purchase the power generated by the renewable energy system from the third party at agreed upon energy rates. Energy Savings Improvement Program (ESIP): Public Law 2009, Chapter 4 authorizes government entities to make energy related improvements to their facilities and pay for the costs using the value of energy savings that result from the improvements. The “Energy Savings Improvement Program (ESIP)” law provides a flexible approach that can allow all government agencies in New Jersey to improve and reduce energy usage with minimal expenditure of new financial resources. This program provides public entities to make valuable facility infrastructure improvements that are associated with energy savings. All energy savings projects are eligible as long as the financing period does not extend beyond 15 years. The financing can be utilized for all aspects of energy efficiency project implementation including, energy savings plan development, engineering, construction management, construction management, commissioning, and measurement and verification. This program provides the much needed financing for energy efficiency projects without the burden of increased debt. The program allows for procurement of financing without voter approval or extending existing dept. The program requires evaluation to ensure a positive cash-flow through the entire 15 year financing period. The first phase of implementing an ESIP is the development of an Energy Savings Plan (ESP) to verify the energy savings, construction costs, and overall financial model. See ESIP summary table within the Executive Summary. The underlining program requirement is the limitation of the project term to 15 years. The ESIP project size is open for multiple buildings to be included within one project. In addition all applicable incentive programs can also be utilized to help reduce the overall construction cost.

II. FACILITY DESCRIPTION
The 68,022 SF Cedar Hill Elementary School is a single story facility comprised of classrooms, library, computer room, cafeteria, kitchen, gymnasium, administration offices, restrooms, boiler rooms, custodial spaces and storage spaces. The School was built in 1956 with additions added in 1991 and 1994. In 1994 the 500 wing was added to the building
Building Profile
The hours of operation for the school students and teachers are between 8:30 AM and 3:30 PM on the weekdays. The facility remains occupied between 3:30 PM and 6:00 PM for aftercare during the weekdays. Custodial services are performed between the hours of 6:00 PM and 11:00 PM. The facility is closed on weekends. The student enrollment at Cedar Hill School is approximately 586 students and 73 teachers.
Building Envelope
The facility exterior is constructed of 8-inch sinter blocks with 4-inch stone and brick façade. Insulation within the original building is estimated to consist of an air space between the block wall and brick façade. The new 500 wing (1994 addition) to building is estimated to have 1”-2” of rigid insulation within the wall. The roof on the building is a flat built up style roof with tar coating and crushed stone on top. The gymnasium has a newer style built up flat roof with rigid insulation (estimated 2” minimum) and a black rubber roof membrane. The windows throughout the facility are double pane aluminum frame windows. These are in good condition and appear to be providing a tight weather barrier. Blinds for the windows integral to the double pane window system and appear to be in good working order.
HVAC Systems
Heating is provided by a central hot water heating system. The facility utilizes two cast iron sectional style boilers. Each of the Weil McLain 88 Series boilers has an input capacity of 4,474 MBH. These boilers provide heating hot water to baseboards, unit ventilators, and heating and ventilation units throughout the school. The boilers are in good condition and appear to be maintained. At the time of the survey, one boiler was not operational due to a false flame out signal from the burner. This is scheduled to be fixed.
Terminal heating equipment consists of unit ventilators made by Nesbitt in combination with hydronic baseboard heat. These units serve the various classrooms throughout the school with the exception of the 500 wing. The unit ventilators appear to be original and poor condition. The unit ventilators have since been retrofitted with electronic controls that include electronic temperature sensors, damper actuators, and control valves.
The building also utilizes large heating and ventilation units that provide heat for the large open areas such as the gymnasium and cafeteria. These units appear to be original to the building and in poor condition, however, these units are operational and adequately providing heat for the space.
Bernards Public Schools – Cedar Hill Elementary School Energy Audit
Concord Engineering Group, Inc. 9C10088 April 15, 2011– FINAL Page 8 of 43
In addition to the hot water system, several spaces utilized packaged roo0ftop heating and cooling units for heat with gas fired heat exchangers. Packaged units with natural gas heat provides heat for various classrooms in the 300 wing, the 600 area offices, as well as all of the 500 wing.
Cooling is provided for only a portion of the rooms at Cedar Hill Elementary. Approximately 1/3rd of the rooms within the original building have some form of cooling. All of the 500 wing includes cooling. Air conditioning is provided by a combination of packaged rooftop unit, split systems, ductless split systems, and a few window AC units. All packaged rooftop units with gas heat include DX cooling, while additional packaged units are cooling only. Packaged cooling rooftop units provide cooling for the 600 area offices, various rooms in the 300 wing, all of the 500 wing, and main office. Split system AC units are provided for the faculty room, and nurses office. A large split system AC unit is provided for the music room. Various ductless split systems were installed for various classrooms as well as the technology IT room. All units were noted to be operational.
The packaged units throughout the 500 wing are in fair condition and appear to be working properly. The remaining units over the original building are in fair or poor condition. The ductless split systems are in fair or good condition depending on the age of the equipment. The two small split systems serving the faculty and nurse’s office are in poor condition. The music room AC unit appears to be oversized for the space and it was noted that the space used to be the school computer room. The condensing unit for the music room split system appears to have been replaced and good condition.
Exhaust System
Exhaust is provided by roof top mounted exhaust fans primarily located over the hallways. The exhaust fans are utilized to relieve the excess building pressure due to outside air brought in through the unit ventilators and packaged rooftop units. It is unknown if these units operate based on a time schedule and shut down in occupied mode. Bathrooms and toilet rooms are exhausted through smaller rooftop exhaust fans typically interlocked with the bathroom wall switch.
The kitchen includes a 4ft x 12ft commercial exhaust hood, which provides exhaust for cooking equipment. The kitchen hood is manually controlled with a wall switch. It is reported that the exhaust hood operates approximately 6 hours per day.
HVAC System Controls
The building HVAC systems are controlled by a Staefa Control System. Since 1998 this system has become a brand of Siemens Building Technologies. The Staefa Control System appears to have been retrofitted throughout the building unit ventilators to provide improved control over the unit ventilator outside air dampers, hot water control valves, and temperature sensors.
The building also utilizes a pneumatic air compressor for an pneumatic system. It is unknown what this system is currently controlling or if all pneumatic controls throughout the building have
Bernards Public Schools – Cedar Hill Elementary School Energy Audit
Concord Engineering Group, Inc. 9C10088 April 15, 2011– FINAL Page 9 of 43
been replaced. The air compressor is typically operational. At the time of the survey, the air compressor was down for service.
Domestic Hot Water
Domestic hot water is provided to the school by two domestic hot water tanks. The main facility utilizes a 65 gallon natural gas hot water heater made by Bradford White in excellent condition. The main building HWH is located in the main boiler room and appears to have been recently replaced. The central boiler system includes a heat exchanger and large domestic hot water tank that is no longer used for domestic hot water production. Domestic hot water is circulated to the bathrooms and sinks by a small re-circ pump controlled by an aqua stat.
The 500 wing has a dedicated tank type natural gas hot water heater that provides hot water to the bathroom group within the 500 wing, which is in good condition.
Lighting Typical lighting throughout school building is fluorescent tube lay-in fixtures with T-12 lamps and magnetic ballasts. Some of the storage rooms and closets including the boiler room is lit with a mixture of incandescent lamps and compact fluorescent lamps. The gym lighting is provided with 400W metal halide fixtures. .

ECM #1: Lighting Upgrade – Interior and Exterior Description: The majority of the interior lighting throughout Cedar Hill Elementary School building is provided with fluorescent fixtures with older generation, 700 series 32W T8 lamps and electronic ballasts. Although 700 series T8 lamps are considered fairly efficient, further energy savings can be achieved by replacing the existing T8 lamps with new generation, 800 series 28W T8 lamps without compromising light output. CEG recommends, re-lamping all of the fixtures with 28W T8 lamps. In addition, some of the storage areas, locker room and gym areas, offices, auditorium, classrooms, restrooms and kitchen areas still have a variety of older fluorescent fixtures with magnetic ballasts and incandescent lamps. It is recommended to retrofit or replace all of the older fluorescent fixtures and the incandescent lights in these areas with high efficiency fluorescent T8 or T5 fixtures with electronic ballasts or compact fluorescent lamps. This ECM includes re-lamping of the existing fluorescent fixtures with 800 series, 28W T8 lamps. The ECM also includes retrofit of all older fluorescent fixtures with T8 or T5 fluorescent fixtures with electronic ballasts in the building. The new, energy efficient T8 fixtures will provide adequate lighting and will save on electrical costs due to better performance of the lamp and ballasts. This ECM also includes maintenance savings through the reduced number of lamps replaced per year. The expected lamp life of a T8 lamp is approximately 30,000 burn-hours, in comparison to the existing T12 lamps which is approximately 20,000 burn-hours. The facility will need approximately 33% less lamps replaced per year for each one for one fixture replaced. The ECM also includes replacement of any incandescent lamps with compact fluorescent lamps. Compact fluorescent lamps (CFL’s) were designed to be direct replacements for the standard incandescent lamps which are common to table lamps, spot lights, hi-hats, bathroom vanity lighting, etc. The light output of the CFL has been designed to resemble the incandescent lamp. The color rendering index (CRI) of the CFL is much higher than standard fluorescent lighting, and therefore provides a much “truer” light. The CFL is available in a myriad of shapes and sizes depending on the specific application. Typical replacements are: a 13-Watt CFL for a 60-Watt incandescent lamp, an 18-Watt CFL for a 75-Watt incandescent lamp, and a 26-Watt CFL for a 100-Watt incandescent lamp. The CFL is also available for a number of “brightness colors” that is indicated by the Kelvin rating. A 2700K CFL is the “warmest” color available and is closest in color to the incandescent lamp. CFL’s are also available in 3000K, 3500K, and 4100K. The 4100K would be the “brightest” or “coolest” output. A CFL can be chosen to screw right into your existing fixtures, or hardwired into your existing fixtures. Where the existing fixture is controlled by a dimmer switch, the CFL bulb must be compatible with a dimmer switch. In some locations the bulb replacement will need to be tested to make sure the larger base of the CFL will fit into the existing fixture. The energy usage of an incandescent compared to a compact fluorescent approximately 3 to 4 times greater. In addition to the energy savings, compact fluorescent fixtures burn-hours are 8 to 15 times longer than incandescent fixtures ranging from 6,000 to 15,000 burn-hours compared to incandescent fixtures ranging from 750 to 1000 burn-hours. However, the maintenance savings due to reduced lamp replacement is offset by the higher cost of the CFL’s compared to the incandescent lamps.

ECM #2: Lighting Controls Upgrade – Occupancy Sensors Description: Some of the lights in the school building are left on unnecessarily. In many cases the lights are left on because of the inconvenience to manually switch lights off when a room is left or on when a room is first occupied. This is common in rooms that are occupied for only short periods and only a few times per day. In some instances lights are left on due to the misconception that it is better to keep the lights on rather than to continuously switch lights on and off. Although increased switching reduces lamp life, the energy savings outweigh the lamp replacement costs. The payback timeframe for when to turn the lights off is approximately two minutes. If the lights are expected to be off for at least a two minute interval, then it pays to shut them off.
Lighting controls come in many forms. Sometimes an additional switch is adequate to provide reduced lighting levels when full light output is not needed. Occupancy sensors detect motion and will switch the lights on when the room is occupied. Occupancy sensors can either be mounted in place of a current wall switch, or on the ceiling to cover large areas. The U.S. Department of Energy sponsored a study to analyze energy savings achieved through various types of building system controls. The referenced savings is based on the “Advanced Sensors and Controls for Building Applications: Market Assessment and Potential R&D Pathways,” document posted for public use April 2005. The study has found that commercial buildings have the potential to achieve significant energy savings through the use of building controls. The average energy savings are as follows based on the report:
• Occupancy Sensors for Lighting Control 20% - 28% energy savings.
Savings resulting from the implementation of this ECM for energy management controls are estimated to be 20% of the total light energy controlled by occupancy sensors and daylight sensors (The majority of the savings is expected to be after school hours when rooms are left with lights on) This ECM includes installation of ceiling or switch mount sensors for individual offices, classrooms, large bathrooms, and libraries. Sensors shall be manufactured by Sensorswitch, Watt Stopper or equivalent. The Investment Grade Lighting Audit Appendix of this report includes the summary of lighting controls implemented in this ECM and outlines the proposed controls, costs, savings, and payback periods. The calculations adjust the lighting power usage by the applicable percent savings for each area that includes lighting controls. Energy Savings Calculations:

ECM #3: Computer Monitor Replacement Description: The computers throughout the facility utilize a mixture of CRT computer monitors and LCD computer monitors. The CRT computer monitors within the offices and classrooms are outdated and have several disadvantages such as; significantly increased energy consumption, uses large amount of desk space, poor picture quality, distortions and flickering image, secular glare problems, high weight, and electromagnetic emissions. Many of these drawbacks are difficult to quantify except for the energy use. CRT monitors use considerably more energy than an alternative flat panel LCD monitor. Replacement of the existing CRT monitors with LCD monitors saves considerable energy as well as provides other ergonomic benefits. Based on the site survey it was noted that there are 21 LCD monitor and 143 CRT monitors. Some of the monitors were left in screen saver mode, which only saves the computer screen from image burn in, however it does not save on energy consumption. The average operating hours for all computers and monitors is estimated based on the site survey observations. Energy consumption of computer monitors is based on averages for power usage of various computer monitors. This ECM includes replacement of all existing CRT monitors with LCD flat panel monitors throughout the facility. Installation costs were neglected for this ECM with the intention that this ECM would be replaced by the school district. The calculations are based on the following operating assumptions: Energy Savings Calculations: No. of CRT Monitors: 143 Operating Weeks per Yr: 42 Hrs per Week: 60 (12 hrs per day estimated average)

ECM #4: Air Conditioning Unit Upgrades
Description:
Cedar Hill Elementary is air conditioned by split system AC units and packaged rooftop units. The majority of the units at the elementary schools with the exception of the ductless split systems, are in poor condition and in need of replacement. The units currently installed are inefficiency compared to modern equipment and can be replaced with new high efficiency units. New air conditioners provide higher full load and part load efficiencies due to advances in inverter motor technologies, heat exchangers and refrigerants. This ECM includes one-for-one replacement of the older air conditioning units with new higher efficiency systems. It is recommended to fully evaluate the capacity needed for all new systems prior to moving forward with this ECM. A summary of the unit replacements for this ECM can be found in the table below:

IMPLEMENTATION SUMMARY
The manufacturers used as the basis for design are Trane, Carrier, Mitsubishi, and Fujitsu. This ECM includes replacement of the outdoor condensing units and associated indoor air handling units or cooling coils where appropriate. The RTU replacements include full unit replacements. All units are one for one style replacements with matching capacity of the new units to the old units with the exception of the Music room. Based on review of the existing music room size and estimated cooling load, it was determined that the existing cooling unit is oversized for the load. The music room savings is based on two (2) 2.0 ton ductless split style units in lieu of the existing 6 ton Split System. The operating efficiency of the oversized cooling unit is estimated based on the current operating condition. Energy Savings Calculations:

ECM #5: Demand Controlled Ventilation Demand Controlled Ventilation (DCV) is a means to provide active, zone level control of ventilation for spaces within a facility. The basic premise behind DCV is monitoring indoor CO2 levels versus outdoor CO2 levels in order to provide proper ventilation to the spaces within the facility as well as saving costly dollars treating unconditioned ventilation air. Carbon dioxide ventilation control or demand controlled ventilation (DCV) allows for the measurement and control of outside air ventilation levels to a target cfm/person ventilation rate in the space (i.e., 15 cfm/person) based on the number of people in the space. It is a direct measure of ventilation effectiveness and is a method whereby buildings can regain active and automatic zone level ventilation control, without having to open windows. The fixed ventilation approach depends on a set-it-and-forget-it methodology that is completely unresponsive to changes in the way spaces are utilized/occupied or how equipment is maintained. A DCV system utilizes various control algorithms to maintain a base ventilation rate. The system monitors space CO2 levels and the algorithm automatically adjusts the outdoor and return air dampers to provide the quantity of outdoor air to maintain the required CO2 level in the space. System designs are normally designed for maximum occupancy and the ventilation rates are designed for this (maximum) occupancy. In areas where occupancy swings are prevalent there is ample opportunity to reduce outdoor air quantity to satisfy the needs of the actual number of occupants present. By installing the DCV controls, energy savings are realized by the reduced quantities of outdoor air that do not require heating energy from the boiler plant. There are large heating and ventilation units (H&V) providing heating and air conditioning to the gymnasium. When operating, these units provide minimum amount of outside air to the space. The outside air volume is typically based on the maximum occupancy of the space conditioned. When a given space is not fully occupied the outside air quantity delivered to the space is greater than the amount needed for adequate ventilation. This ECM includes the installation of CO2 sensors integrated into a demand control ventilation system, for the units mentioned above. The components required for the demand control ventilation system installation include damper actuators, CO2 sensors, wiring, controls equipment and programming. The gymnasium would require one CO2 sensor installed per unit to monitor occupancy levels. Often heating and air conditioning units switch to occupied mode several hours before the actual occupancy in order to provide pre-heating or pre-cooling of the space. Energy savings achieved through “Demand Control Ventilation” is calculated based on actual occupancy of the spaces and the hours the units are in occupied mode. Energy Savings Calculations:

ECM #6: Valve Blanket and Pipe Insulation
Description: The boiler plant supplies heating hot water to the facility for heating season. The piping remains heated at approximately 180°F continuously during this period (approximately 6 months). Un-insulated piping has significant heat losses due to the exposure of the steel piping to the surrounding air. Insulated piping has a heat loss which is a small fraction of the heat loss from un-insulated piping. It was noted that significant piping within the boiler room was missing piping insulation including numerous valves throughout the system. Based on the site survey approximately 9 large diameter pipe valves/fittings and 10 feet of 6” steel pipe was not insulated. Valve blankets are designed to provide insulation value over large hydronic valves that must remain accessible. This ECM includes installation of valve blankets on all exposed boiler system valves and insulation of all un-insulated piping within the boiler room. Energy Savings Calculations: Heat Loss for un-insulated steel piping is based on ASHRAE 2009 Fundamentals – “Insulation for Mechanical Systems” Bare Steel Piping Heat Loss 6” pipe: 373 BTU/HR per Linear FT

ECM #7: Condensing Boiler Installation Description: Space heating for the perimeter offices and classrooms in the majority of the school is provided with unit ventilators and cabinet heaters with hot water coils and hot water radiators. The source of hot water for this equipment is two (2) hot water boilers located in the main boiler room. The input capacity of the boilers is 4.474 MMBH (106 BTU/H) each. The boilers appear to be close to their rated life; however, this is not necessarily a good indicator of the end of useful life particularly when boilers are well maintained. This ECM provides insight into the energy efficiency benefit of condensing boiler technology compared to standard cast iron boilers. Standard (non-condensing) boilers provide lower than nominal efficiency compared to condensing boilers. Standard boilers suffer further efficiency losses at part load operating conditions mainly due to limitations in the reduction of the flue gas temperature. Current average combustion efficiency of each boiler is estimated to be 75% due to standard non-condensing boiler technology, limited turn down ratio, cycling losses and outdated design and controls. A new condensing boiler could substantially improve the operating efficiency of the heating system of the building. Condensing boiler’s peak efficiency tops out at 99% depending on return water temperature. This ECM is based on the replacement of the two (2) boilers with condensing hot water boilers to provide the building with heating throughout the year. The annual average operating efficiency of the proposed boiler set is expected to be 90%, which gives the heating system a 15% increase in efficiency. This ECM is based on variable supply water temperature adjusted based on outdoor temperature. This ECM includes installation of three (3) new condensing gas fired boilers to replace two (2) existing hot water boilers. The basis for this ECM is Aerco Benchmark 2.0 condensing hot water boilers or equivalent. New boilers shall be setup and programmed to be the primary source of heating for the building during entire year. The owner is recommended to retain a professional engineer to confirm equipment sizing and finalize design.
Energy Savings Calculations: Currently there are multiple boilers and gas fired rooftop units on the building gas meter. The boilers’ gas usage is not separately metered. Therefore, annual energy consumption of the boilers has to be estimated. This calculation is based on the energy consumption of the boilers in proportion with the ratio of the total heating capacity of each gas fired piece of equipment. First, domestic hot water usage is estimated and subtracted from the total usage in order to estimate the net natural gas usage for space heating. Current total hot water usage can be found in the table below:

ECM #8: Install NEMA Premium® Efficiency Motors Description: The improved efficiency of the NEMA Premium® efficient motors is primarily due to better designs with use of better materials to reduce losses. Surprisingly, the electricity used to power a motor represents 95 % of its total lifetime operating cost. Because many motors operate continuously 24 hours a day, even small increases in efficiency can yield substantial energy and dollar savings. The electric motors driving the hot water pumps and supply fans in some of the HVAC equipment are candidates for replacing with premium efficiency motors. These standard efficiency motors run considerable amount of time over a year. This energy conservation measure replaces existing inefficient electric motors with NEMA Premium® efficiency motors. NEMA Premium® is the most efficient motor designation in the marketplace today.

ECM #9: Install Pump VFD’s Description: The heating system at Cedar Hill utilizes constant speed pumps to circulate hot water throughout the building. Based on the survey of the existing equipment is appears that the majority of the existing unit ventilators and large air handling units utilize 2-way control valves for flow control. It was noted that the gymnasium units have 3-way control valves which allow continuous flow through the piping loop. 2-way control valves provide flow through the heat exchanger equipment only when there is a call for heating or cooling, unlike 3-way control valves that allow constant flow of the water loop. 3-way control valves require full pumping energy continuously, while 2-way control valves allow the system to reduce flow when it is not needed. The result of this mixed control system forces the system flow to vary with load, however the pump speed remains the same. The overall pump energy is increased due to the constant speed of the pump. This measure includes capping off the bypass port on the 3-way control valves which effectively turns the valves into “2-way” control valves. When the unit ventilator or heating and ventilation unit is not calling for heating, the control valve closes reducing overall flow of the system. Variable frequency drives allow the pumps to slow down in response to a reduction in overall system flow. The reduction in operating flow allows the pumps to reduce energy consumption for all hours that the heating system is not at its peak load. This ECM also includes the installation of Variable Frequency Drives on the two (2) existing 7.5 horsepower hot water pumps in conjunction with piping modifications at all units with 3-way control valves to cap off the bypass port. The VFD control is based on a differential pressure sensor in the water loop to measure demand for water. The furthest unit ventilators from the loop pumps would remain as 3-way control valves (constant flow) to eliminate dead heading potential. This ECM also includes replacement of the existing pump motors with inverter duty motors that meet NEMA Premium Efficiency Standard, which also helps to reduce energy consumption. Energy and cost savings calculations are based on calculation software “PumpSave v4.2,” provided by ABB. The PumpSave calculation software is used to estimate the pumping energy for variable speed pump systems. The boiler water loop pump operation is estimated to be 4,380 Hrs per year since this system is used for about 6 months total. The pump flow, HD, and resultant energy are calculated based on the existing pump horse power installed. Energy Savings Calculations: The existing energy consumption is based a typical pump energy curve for “Throttled flow control.” The throttled flow control is compared with variable speed control as a result of the VFD installation.

V. ADDITIONAL RECOMMENDATIONS The following recommendations include no cost/low cost measures, Operation & Maintenance (O&M) items, and water conservation measures with attractive paybacks. These measures are not eligible for the Smart Start Buildings incentives from the office of Clean Energy but save energy none the less.
A. Chemically clean the condenser and evaporator coils periodically to optimize efficiency. Poorly maintained heat transfer surfaces can reduce efficiency 5-10%.
B. Maintain all weather stripping on windows and doors.
C. Clean all light fixtures to maximize light output to avoid use of task lighting.
D. Provide more frequent air filter changes to decrease overall system power usage and maintain better IAQ.
E. Turn off computers when not in use. Ensure computers are not running in screen saver mode which saves the monitor screen not energy.
F. Ensure outside air dampers are functioning properly and only open during occupied mode.
It was noted at the site survey that the HVAC systems in several rooms were not controlling temperature correctly. The result of the controls issues causes space temperatures to become uncomfortable and drastic measures such as opening windows on extremely cold days. This type of issue requires a whole system controls evaluation for the building to determine where control problems are taking place. Based on information provided by the operations personnel, there are several control systems within the building which operate different section or systems throughout the building. In addition, multiple control vendors are utilized to maintain the control systems. The use of multiple control systems and control vendors to support the systems will very likely cause issues with the overall function of the building. The systems and controls throughout the district represent a large potential “energy leak” throughout the building. It is recommended to quantify the control system points and verify their proper operation through Retro-Commissioning. Retro-Commissioning allows facility owners to re-establish the operation of the HVAC systems back to the original specifications. A third party evaluation is highly recommended to review the controls of the systems and provide insight into the corrections needed. It is also recommended to consider the renovation of all control systems into one central control system to avoid the overlap and communication gap when utilizing multiple control systems. This renovation should be consistent across all facility throughout Bernards Public Schools to maximize the benefit of central controls.

ECM #1: Lighting Upgrade – Interior and Exterior Description: The majority of the interior lighting throughout the Liberty Corner Elementary School building is provided with fluorescent fixtures with older generation, 700 series 32W T8 lamps and electronic ballasts. Although 700 series T8 lamps are considered fairly efficient, further energy savings can be achieved by replacing the existing T8 lamps with new generation, 800 series 28W T8 lamps without compromising light output. CEG recommends, re-lamping all of the fixtures with 28W T8 lamps. In addition, some of the storage areas, locker room and gym areas, offices, auditorium, classrooms, restrooms and kitchen areas still have a variety of older fluorescent fixtures with magnetic ballasts and incandescent lamps. It is recommended to retrofit or replace all of the older fluorescent fixtures and the incandescent lights in these areas with high efficiency fluorescent T8 or T5 fixtures with electronic ballasts or compact fluorescent lamps. This ECM includes re-lamping of the existing fluorescent fixtures with 800 series, 28W T8 lamps. The ECM also includes retrofit of all older fluorescent fixtures with T8 or T5 fluorescent fixtures with electronic ballasts in the building. The new, energy efficient T8 fixtures will provide adequate lighting and will save on electrical costs due to better performance of the lamp and ballasts. This ECM also includes maintenance savings through the reduced number of lamps replaced per year. The expected lamp life of a T8 lamp is approximately 30,000 burn-hours, in comparison to the existing T12 lamps which is approximately 20,000 burn-hours. The facility will need approximately 33% less lamps replaced per year for each one for one fixture replaced. The ECM also includes replacement of any incandescent lamps with compact fluorescent lamps. Compact fluorescent lamps (CFL’s) were designed to be direct replacements for the standard incandescent lamps which are common to table lamps, spot lights, hi-hats, bathroom vanity lighting, etc. The light output of the CFL has been designed to resemble the incandescent lamp. The color rendering index (CRI) of the CFL is much higher than standard fluorescent lighting, and therefore provides a much “truer” light. The CFL is available in a myriad of shapes and sizes depending on the specific application. Typical replacements are: a 13-Watt CFL for a 60-Watt incandescent lamp, an 18-Watt CFL for a 75-Watt incandescent lamp, and a 26-Watt CFL for a 100-Watt incandescent lamp. The CFL is also available for a number of “brightness colors” that is indicated by the Kelvin rating. A 2700K CFL is the “warmest” color available and is closest in color to the incandescent lamp. CFL’s are also available in 3000K, 3500K, and 4100K. The 4100K would be the “brightest” or “coolest” output. A CFL can be chosen to screw right into your existing fixtures, or hardwired into your existing fixtures. Where the existing fixture is controlled by a dimmer switch, the CFL bulb must be compatible with a dimmer switch. In some locations the bulb replacement will need to be tested to make sure the larger base of the CFL will fit into the existing fixture. The energy usage of an incandescent compared to a compact fluorescent approximately 3 to 4 times greater. In addition to the energy savings, compact fluorescent fixtures burn-hours are 8 to 15 times longer than incandescent fixtures ranging from 6,000 to 15,000 burn-hours compared to incandescent fixtures ranging from 750 to 1000 burn-hours. However, the maintenance savings due to reduced lamp replacement is offset by the higher cost of the CFL’s compared to the incandescent lamps.

Finally, the exterior of the Liberty Corner Elementary School is illuminated with 400W Probe Start Metal Halide fixtures in “Shoe Box” fixtures. It is recommended to retrofit these fixtures with pulse start metal halide lamps and electronic ballasts. Pulse-start MH lamps have a high-voltage ignitor to start the lamp using a series of pulses instead of a starting probe electrode. Pulse start metal halide lamps typically have an increased lumen maintenance levels by up to 33%. This allows utilizing lower wattage lamps while maintaining the minimum lighting levels in the space. This ECM retrofits existing probe start metal halide fixtures with pulse start metal halide fixtures. The bulb replacement cost for the new lamps compared to the existing lamps were found to be approximately equal and therefore not included in the savings calculations. Energy Savings Calculations: The Investment Grade Lighting Audit Appendix outlines the hours of operation, proposed retrofits, costs, savings, and payback periods for each set of fixtures in the each building. Rebates and Incentives: There are incentives available from NJ Smart Start® Program for a portion of the retrofits in this ECM. Incentives are calculated as follows: From the Smart Start Incentive appendix, the retrofit of a probe start metal halide with a pulse start system (with a minimum 12% wattage reduction) warrants the following incentive: Pulse Start Metal Halide (for fixtures ≥ 150 watts) = $25 per fixture.

ECM #2: Lighting Upgrade – Gymnasium Description: The gymnasium at the Liberty Corner Elementary School utilizes 400W low bay mercury vapor fixtures for its lighting. Mercury vapor lamps provide a reasonably efficient option for bay lighting with a few draw-backs that are common. Mercury vapor fixtures often have poor overall efficacy which limits the amount of light actually leaving the fixture. Also mercury vapor lamps require a significant warm-up period and even longer cool down period eliminating the potential for occupancy sensors frequent switching. This symptom encourages the gymnasium lighting to be left on continuously during the day. Another drawback is the reduced lumen output (Lumen Maintenance) of the mercury vapor lamp over its life time. Average bulb output or “mean lumens,” is approximately 25% less than the bulb’s initial lumens for typical mercury vapor lamps. In addition the most rapid rate of light output decline is during the beginning of its life, approximately 20% light loss within the first 20% of its rated life. It is important to note that the light loss has no savings in energy used; therefore the overall light efficiency is continuously decreasing with age. The final drawback is the light quality or Color Rendering Index (CRI). Typical values for coated mercury vapor lamps is approximately 50, which is a measure of how close the light is to true “full spectrum” light produced by sunlight or incandescent lighting. Mercury vapor lamps also show noticeable color shifting when the bulb is reaching the end of its life. Utilizing fluorescent fixtures in low and high bay spaces is a superior option over high intensity discharge fixtures such as mercury vapor fixtures in all areas described above. Although mercury vapor fixtures provide light fairly efficiently at the start of the bulb life, the average efficiency over the life is below that of fluorescent fixtures. This ECM includes replacement of each of the existing gymnasium mercury vapor light fixtures with T5HO fixtures with reflective lenses and wire cage protection. The retrofit for the mercury vapor fixtures includes a one for one fixture replacement. The fluorescent fixtures selected will provide equivalent light compared to the average light output of the existing mercury vapor fixtures. The bulb replacement cost for T-5 HO lamps compared to the existing mercury vapor lamps were found to be approximately equal and therefore not included in the savings calculations.

ECM #3: Lighting Controls Upgrade – Occupancy Sensors Description: Some of the lights in the school building are left on unnecessarily. In many cases the lights are left on because of the inconvenience to manually switch lights off when a room is left or on when a room is first occupied. This is common in rooms that are occupied for only short periods and only a few times per day. In some instances lights are left on due to the misconception that it is better to keep the lights on rather than to continuously switch lights on and off. Although increased switching reduces lamp life, the energy savings outweigh the lamp replacement costs. The payback timeframe for when to turn the lights off is approximately two minutes. If the lights are expected to be off for at least a two minute interval, then it pays to shut them off.
Lighting controls come in many forms. Sometimes an additional switch is adequate to provide reduced lighting levels when full light output is not needed. Occupancy sensors detect motion and will switch the lights on when the room is occupied. Occupancy sensors can either be mounted in place of a current wall switch, or on the ceiling to cover large areas. The U.S. Department of Energy sponsored a study to analyze energy savings achieved through various types of building system controls. The referenced savings is based on the “Advanced Sensors and Controls for Building Applications: Market Assessment and Potential R&D Pathways,” document posted for public use April 2005. The study has found that commercial buildings have the potential to achieve significant energy savings through the use of building controls. The average energy savings are as follows based on the report:
• Occupancy Sensors for Lighting Control 20% - 28% energy savings.
Savings resulting from the implementation of this ECM for energy management controls are estimated to be 20% of the total light energy controlled by occupancy sensors and daylight sensors (The majority of the savings is expected to be after school hours when rooms are left with lights on) This ECM includes installation of ceiling or switch mount sensors for individual offices, classrooms, large bathrooms, and libraries. Sensors shall be manufactured by Sensorswitch, Watt Stopper or equivalent. The Investment Grade Lighting Audit Appendix of this report includes the summary of lighting controls implemented in this ECM and outlines the proposed controls, costs, savings, and payback periods. The calculations adjust the lighting power usage by the applicable percent savings for each area that includes lighting controls. Energy Savings Calculations:

ECM #4: Computer Monitor Replacement Description: The computers throughout the school utilize a mixture of CRT computer monitors and LCD computer monitors. The CRT computer monitors within the offices and classrooms are outdated and have several disadvantages such as; significantly increased energy consumption, uses large amount of desk space, poor picture quality, distortions and flickering image, secular glare problems, high weight, and electromagnetic emissions. Many of these drawbacks are difficult to quantify except for the energy use. CRT monitors use considerably more energy than an alternative flat panel LCD monitor. Replacement of the existing CRT monitors with LCD monitors saves considerable energy as well as provides other ergonomic benefits. Based on the site survey it was noted that there are 26 LCD monitor and 112 CRT monitors. Some of the monitors were left in screen saver mode, which only saves the computer screen from image burn in, however it does not save on energy consumption. The average operating hours for all computers and monitors is estimated based on the site survey observations. Energy consumption of computer monitors is based on averages for power usage of various computer monitors. This ECM includes replacement of all existing CRT monitors with LCD flat panel monitors throughout the facility. Installation costs were neglected for this ECM with the intention that this ECM would be replaced by the school district. The calculations are based on the following operating assumptions: Energy Savings Calculations: No. of CRT Monitors: 112 Operating Weeks per Yr: 26 Hrs per Week: 60 (12 hrs per day estimated average)

ECM #5: Commercial Kitchen Exhaust Hood Controls Description: The kitchen in this facility is equipped with a large commercial kitchen exhaust hood providing exhaust for the cooking equipment. The estimated total kitchen exhaust from the hoods is 4,800 CFM powered by an estimated total 3 HP of exhaust fans. The kitchen make-up air unit and the cafeteria air handling units provide conditioned air to replace all the air exhausted through the exhaust hood. This system operates based on manual switches located in the kitchen. Currently the facility provides 1 meal per day. The installation of kitchen exhaust controls would significantly reduce the total kitchen exhaust and make-up air quantity. The conditioned make up air and exhausted air savings are achieved by monitoring the exhaust hoods and exhaust based on the actual use of the kitchen equipment. Temperature sensors and optical lasers monitor the heat and smoke production at each exhaust hood to reduce the exhaust and make-up airflow based on the need of the kitchen equipment. This ECM includes installation of kitchen exhaust controls for the main kitchen exhaust hood and VFD’s for the constant volume exhaust fans. The hoods would be retrofitted with temperature and laser sensors to monitor the activity of each of all equipment installed below the hoods. The work involves installing a Melink Kitchen Hood Variable Air Volume Controller; variable frequency drive on the kitchen hood exhaust fan; and turn off all the kitchen hood exhaust systems when the kitchen is closed. When the cooking appliances are turned on, the hood exhaust fan speed will increase based on the hood exhaust temperature. During heavy cooking, the kitchen hood exhaust fan increases to 100% speed until the smoke/vapor is removed. Energy savings are also realized when the kitchen equipment is operating at less than full load due to minimal cooking operations. During these times the fan speed decreases, removing only the necessary amount of air, saving exhaust fan energy and make up air conditioning energy. Energy Calculations Summary: Detailed calculations for the proposed kitchen hood control system can be found in the Kitchen Exhaust Calculations Appendix. It is pertinent to note that the calculation assumes the exhaust fans and make-up air unit remain off for approximately 17 hours per day. Installed cost of the kitchen hood control system is $19,000. The calculated energy savings equals approximately $663 per year. Currently, there aren’t any incentives from the Smart Start program for motors smaller than 5 HP.

ECM #6: Condensing Boiler Installation Description: Space heating for the perimeter offices and classrooms in the majority of the school is provided with unit ventilators and cabinet heaters with hot water coils and hot water radiators. The sources of hot water for these equipments are three (3) hot water boilers located in the main boiler room and the new section boiler room. Two (2) of the boilers have 3.75 MMBH (106 BTU/H) input capacity while the third (3rd) boiler has 1.35 MMBH. Two (2) larger boilers are 6 years old and the third boiler is approximately 16 years old. All the boilers are within their expected useful life of 30 years defined by ASHRAE. Typically, standard (non-condensing) boilers provide lower than nominal efficiency compared to condensing boilers. Standard boilers suffer further efficiency losses at part load operating conditions mainly due to limitations in the reduction of the flue gas temperature. Current average combustion efficiency of each boiler is estimated to be 75% due to standard non-condensing boiler technology, limited turn down ratio, cycling losses and outdated design and controls. A new condensing boiler could substantially improve the operating efficiency of the heating system of the building. Condensing boiler’s peak efficiency tops out at 99% depending on return water temperature. CEG recommends replacing the three (3) boilers with condensing hot water boilers to provide building with heating throughout the year. The annual average operating efficiency of the proposed boiler set is expected to be 90%, which gives the heating system a 15% increase in efficiency. This ECM is based on variable supply water temperature adjusted based on outdoor temperature. This ECM includes installation of four (4) new condensing gas fired boilers to replace three (3) existing hot water boilers based on following summary.

Energy Savings Calculations: Currently there are multiple boilers and gas fired rooftop units on the building gas meter. The boilers’ gas usage is not separately metered. Therefore, annual energy consumption of the boilers has to be estimated. In this calculation, it is assumed that the energy consumption of the boilers will be in proportion with the ratio of the total heating capacity of each equipment. First, domestic hot water usage is estimated and subtracted from the total usage in order to estimate the net natural gas usage for space heating. Current total hot water usage can be found in the table below:

ECM #7: Install NEMA Premium® Efficiency Motors Description: The improved efficiency of the NEMA Premium® efficient motors is primarily due to better designs with use of better materials to reduce losses. Surprisingly, the electricity used to power a motor represents 95 % of its total lifetime operating cost. Because many motors operate continuously 24 hours a day, even small increases in efficiency can yield substantial energy and dollar savings. The electric motors driving the primary hot water pumps in the main boiler room are candidates for replacing with premium efficiency motors. These standard efficiency motors run considerable amount of time over a year. This energy conservation measure replaces existing electric motors over 5 HP or more with NEMA Premium® efficiency motors. NEMA Premium® is the most efficient motor designation in the marketplace today.

ECM #8: Window Replacement Description: The majority of the facility envelope consists of double pane windows with aluminum frames. There is only small number of older windows with single pane glass and inefficient frames. The windows account for significant energy use through leakage heat loss and conductive heat loss. The age and condition of the windows contribute to the leakage rate of the building. The single pane construction allows higher thermal (conductive) energy loss. These factors lead to increased energy use in the heating season. The heating loss due to single pane glass is combined with heat loss due to poor seals at each operable window. New double pane windows with low E glazing offer a substantial improvement in thermal performance in the summer months. This ECM includes the replacement of all remaining older windows single pane glass in the facility with double pane windows with low emissivity glass. The proposed windows include reduced outside air leakage. In addition the double pane structure will significantly increase the insulation value compared to the existing single pane window structure.

ECM #9: Demand Controlled Ventilation Demand Controlled Ventilation (DCV) is a means to provide active, zone level control of ventilation for spaces within a facility. The basic premise behind DCV is monitoring indoor CO2 levels versus outdoor CO2 levels in order to provide proper ventilation to the spaces within the facility as well as saving costly dollars treating unconditioned ventilation air. Carbon dioxide ventilation control or demand controlled ventilation (DCV) allows for the measurement and control of outside air ventilation levels to a target cfm/person ventilation rate in the space (i.e., 15 cfm/person) based on the number of people in the space. It is a direct measure of ventilation effectiveness and is a method whereby buildings can regain active and automatic zone level ventilation control, without having to open windows. The fixed ventilation approach depends on a set-it-and-forget-it methodology that is completely unresponsive to changes in the way spaces are utilized/occupied or how equipment is maintained. A DCV system utilizes various control algorithms to maintain a base ventilation rate. The system monitors space CO2 levels and the algorithm automatically adjusts the outdoor and return air dampers to provide the quantity of outdoor air to maintain the required CO2 level in the space. System designs are normally designed for maximum occupancy and the ventilation rates are designed for this (maximum) occupancy. In areas where occupancy swings are prevalent there is ample opportunity to reduce outdoor air quantity to satisfy the needs of the actual number of occupants present. By installing the DCV controls, energy savings are realized by the reduced quantities of outdoor air that do not require heating and cooling energy from the steam and chilled water plants. Four (4) packaged rooftop units serving the library, computer lab and rooms #118, 120, 218 and 220 are standard air conditioning units with constant minimum outside air setup. When these units are on unoccupied mode, the outside air dampers shut. The outside air volume is typically based on the maximum occupancy of the space conditioned. When a given space is not fully occupied the outside air quantity delivered to the space is greater than the amount actually needed for adequate ventilation, which results in waste of heating or air conditioning energy. This ECM includes the installation integrated demand control ventilation systems with CO2 sensors, for the units mentioned above. This system allows the air handling unit to respond to changes in occupancy and therefore reduce the amount of outside air that has to be conditioned. Outside air accounts for a large portion of the energy consumption in the HVAC system, especially in high occupancy spaces. The U.S. Department of Energy sponsored a study to analyze energy savings achieved through various types of building system controls. The referenced savings is based on the “Advanced Sensors and Controls for Building Applications: Market Assessment and Potential R&D Pathways,” document posted for public use April 2005. The study has found that commercial buildings have the potential to achieve significant energy savings through the use of building controls. The average energy savings are as follows based on the report:
• Demand Control Ventilation - 10% - 15%.
Energy savings achieved through “Demand Control Ventilation” average 10%-15%. Savings resulting from the implementation of this ECM for energy management controls are estimated to be 15% of the total HVAC energy cost for this system.

The components included to install for a demand control ventilation system include damper actuators (if not exist), Variable Frequency Drives (if not exist), CO2 sensors, wiring, Energy Management System equipment expansion and programming. Each occupied zone would require minimum one CO2 sensor installed to monitor occupancy levels.

ECM #10: Air Conditioning Unit Upgrades
Description:
Liberty Corner Elementary School is air conditioned by split system AC units and packaged rooftop units. The majority of the units at the elementary schools are in fair condition and they have surpassed the end of their useful life of 15 years, which is defined by ASHRAE. The units currently installed are inefficient compared to modern equipment and can be replaced with new high efficiency units. New air conditioners provide higher full load and part load efficiencies due to advances in inverter motor technologies, heat exchangers and refrigerants. This ECM includes one-for-one replacement of the older air conditioning units with new higher efficiency systems. It is recommended to fully evaluate the capacity needed for all new systems prior to moving forward with this ECM. A summary of the unit replacements for this ECM can be found in the table below:

V. ADDITIONAL RECOMMENDATIONS The following recommendations include no cost/low cost measures, Operation & Maintenance (O&M) items, and water conservation measures with attractive paybacks. These measures are not eligible for the Smart Start Buildings incentives from the office of Clean Energy but save energy none the less.
A. Chemically clean the condenser and evaporator coils periodically to optimize efficiency. Poorly maintained heat transfer surfaces can reduce efficiency 5-10%.
B. Maintain all weather stripping on windows and doors.
C. Clean all light fixtures to maximize light output to avoid use of task lighting.
D. Provide more frequent air filter changes to decrease overall system power usage and maintain better IAQ.
E. Turn off computers when not in use. Ensure computers are not running in screen saver mode which saves the monitor screen not energy.
F. Ensure outside air dampers are functioning properly and only open during occupied mode.
It was noted at the site survey that the HVAC systems in several rooms were not controlling temperature correctly. The result of the controls issues causes space temperatures to become uncomfortable and drastic measures such as opening windows on extremely cold days. This type of issue requires a whole system controls evaluation for the building to determine where control problems are taking place. Based on information provided by the operations personnel, there are several control systems within the building which operate different section or systems throughout the building. In addition, multiple control vendors are utilized to maintain the control systems. The use of multiple control systems and control vendors to support the systems will very likely cause issues with the overall function of the building. The systems and controls throughout the district represent a large potential “energy leak” throughout the building. It is recommended to quantify the control system points and verify their proper operation through Retro-Commissioning. Retro-Commissioning allows facility owners to re-establish the operation of the HVAC systems back to the original specifications. A third party evaluation is highly recommended to review the controls of the systems and provide insight into the corrections needed. It is also recommended to consider the renovation of all control systems into one central control system to avoid the overlap and communication gap when utilizing multiple control systems. This renovation should be consistent across all facility throughout Bernards Public Schools to maximize the benefit of central controls.

II. FACILITY DESCRIPTION
The 97,908 SF Elementary School is a two story facility comprised of classrooms, library, computer room, auditorium, cafeteria, kitchen, gymnasium, administration offices, restrooms, boiler room, custodial spaces and storage spaces.
The facility was built in 1998 and expanded towards north-west to accommodate 12 additional classrooms in 2006. The hours of operation for the school students and teachers are between 8:45 am and 3:00 pm on the weekdays. The facility remains occupied between 3:30 and 6:00 PM for the afterschool programs during the weekdays. Custodial services are performed between the hours of 6:00 PM and 10:00 PM. The facility is closed on weekends. The student enrollment at Mt. Prospect Elementary School is approximately 716 students and 150 staff.
U-shaped facility houses the classrooms in the two wings and the major activity areas such as cafeteria and gymnasium in the base. The building exterior constructed of is 8-inch sinter blocks with 4-inch brick façade. Estimated insulation within the wall structure is 2-inches.
The roof structure of the classroom wings are pitched with asphalt shingle covering. Remaining roof areas are built up flat with tar and gravel covering. The amount of insulation within the roof structures is not known. Windows throughout the facility consists of double pane glasses with aluminum frames. Overall condition of the windows throughout the building is excellent. Built-in blinds are utilized throughout the perimeter spaces. The blinds are valuable because they help to reduce heat loss in the winter and reduce solar heat in the summer.
HVAC Systems
The Building heating system consists of two (2) cast iron hot water boilers, which serve the building’s heating hot water loop. The boilers have 4,853 MBH input and 3,830 MBH output capacities resulting in approximately 78% thermal efficiency. Boilers are fitted with PowerFlame variable capacity burners with a maximum 2.5 turndown ratio. The hot water is circulated by two (2) floor mounted, 15 HP constant volume pumps made by Taco. The pumps are driven with standard efficiency motors. Only one pump runs at a time. The pumps provide heating hot water for the classrooms air conditioning units, hot water baseboard heaters and the rooftop heating and air conditioning units.
Heating and ventilation in the classrooms are provided with packaged vertical classroom air conditioning units made by Airedale. There are approximately forty-four (44) classroom units in the building with 3 to 6 ton cooling capacity. All of the units are equipped with hot water coils for heating and packaged direct expansion (DX) unit for cooling. Thirty two (32) of the HVAC units are in the classrooms in the original construction. Two (2) of these units have 6 ton cooling capacity while remaining units have 4 ton cooling capacity. All of the units in the original building are built in 1998 and use R22 refrigerant. Remaining twelve (12) units in the 2006 addition are newer and higher efficiency Airdale models with 3 ton cooling capacity and R410 refrigerant.
Cafeteria, library, kitchen, hallways, gymnasium, nurse’s office, administration offices and some of the classrooms are heated and air conditioned with constant volume, packaged rooftop heating

and air conditioning units located on the southwest roof of the building. Majority of the rooftop units are equipped with hot water coils for heating and DX coils for cooling. Some of the smaller units are equipped with electric preheat coils. All of the units were made by TRANE with capacity ranging from 6 to 30 tons. Larger units are equipped with air side economizer functionality. The units were installed 1998 and in good condition. In addition to the rooftop units, there is a 2 Ton ductless split heat pump unit providing heating and air conditioning to the teacher’s lounge via a ceiling cassette type indoor unit. The unit is in good condition.
The school houses a small commercial kitchen for light cooking. The kitchen appliances include gas cooking ranges, gas warmers, a commercial grade dishwasher, reach in refrigerators, a walk-in refrigerator and a freezer. The walk-in units appear to be in good condition.
Exhaust System
Airdale classroom air conditioning units provide the minimum outside air intake and exhaust in the majority of the classrooms. Some of the classrooms and the office spaces have dedicated exhaust fans located on the roof. The toilet rooms have dedicated roof exhausters as well.
The kitchen includes a 4ft x 16ft commercial exhaust hood, which provides exhaust for cooking equipment. The kitchen hood is manually controlled with a wall switch. It is reported that the exhaust hood operates seldom because of the low cooking activity in the kitchen.
HVAC System Controls
The building HVAC systems are controlled by an I/NET-Seven building automation systems made by T.A.C. The I/NET system is capable of full operation of the classroom HVAC units, rooftop HVAC units, hot water boilers and the hot water pumps. The system modulates the hot water supply temperature to the air side units, outside air damper positions of the rooftop units and the classroom units, economizer functionality of the roof top units and also the time of day scheduling for all the heating and air conditioning units in the facility.
Domestic Hot Water
Domestic hot water for the restrooms and the faucets in the utility rooms is provided with a 300 gallon, gas fired hot water heater made by A.O. Smith. The unit is installed in 1998 during the original construction. The domestic hot water is circulated throughout the building by a hot water circulation pumps. The domestic hot water piping insulation appeared to be in good condition.
The hot water circulators weren’t running during the survey even though the supply pipe was nearly at room temperature.

ECM #1: Lighting Upgrade – Interior spaces Description: The majority of the interior lighting throughout the Mount Prospect Elementary School is provided with fluorescent fixtures with older generation, 700 series 32W T8 lamps and electronic ballasts. Although 700 series T8 lamps are considered fairly efficient, further energy savings can be achieved by replacing the existing T8 lamps with new generation, 800 series 28W T8 lamps without compromising light output. CEG recommends, re-lamping all of the fixtures with 28W T8 lamps. In addition, some of the storage areas, locker room and gym areas, offices, auditorium, classrooms, restrooms and kitchen areas still have a variety of older fluorescent fixtures with magnetic ballasts and incandescent lamps. It is recommended to retrofit or replace all of the older fluorescent fixtures and the incandescent lights in these areas with high efficiency fluorescent T8 or T5 fixtures with electronic ballasts or compact fluorescent lamps. This ECM includes re-lamping of the existing fluorescent fixtures with 800 series, 28W T8 lamps. The ECM also includes retrofit of all older fluorescent fixtures with T8 or T5 fluorescent fixtures with electronic ballasts in the building. The new, energy efficient T8 fixtures will provide adequate lighting and will save on electrical costs due to better performance of the lamp and ballasts. Energy Savings Calculations: The Investment Grade Lighting Audit Appendix outlines the hours of operation, proposed retrofits, costs, savings, and payback periods for each set of fixtures in the each building. Rebates and Incentives: There are no incentives available from NJ Smart Start® Program for the retrofits in this ECM. Replacement and Maintenance Savings: There is no significant replacement and maintenance savings due to implementation of this ECM.

ECM #2: Lighting Upgrade – Multipurpose room Description: The multipurpose room at the Mt. Prospect Elementary School utilizes 400W metal halide fixtures for its lighting. Metal halide bulbs provide a reasonably efficient option for bay lighting however a few draw-backs that are common. Metal halide fixtures often have poor overall efficacy which limits the amount of light actually leaving the fixture. Also metal halide bulbs require a significant warm-up period and even longer cool down period eliminating the potential for occupancy sensors frequent switching. This symptom encourages the gymnasium lighting to be left on continuously during the day. Another drawback is the reduced lumen output (Lumen Maintenance) of the metal halide bulb over its life time. Average bulb output or “mean lumens,” is approximately 25% less than the bulb’s initial lumens for typical metal halide lamps. In addition the most rapid rate of light output decline is during the beginning of its life, approximately 15-20% light loss within the first 20% of its rated life. It is important to note that the light loss has no savings in energy used; therefore the overall light efficiency is continuously decreasing with age. The final drawback is the light quality or Color Rendering Index (CRI). Typical values for metal halide bulbs is 65, which is a measure of how close the light is to true “full spectrum” light produced by sunlight or incandescent lighting. Metal halide bulbs also show noticeable color shifting when the bulb is reaching the end of its life. Utilizing fluorescent fixtures in low and high bay spaces is a superior option over metal halide fixtures in all areas described above. Although metal halide fixtures provide light very efficiently at the start of the bulb life, the average efficiency over the life is below that of fluorescent fixtures. This ECM includes replacement of each of the existing gymnasium high bay metal halide light fixtures with T5HO fixtures with reflective lenses. The retrofit for the metal halide fixtures includes a one for one fixture replacement. The fluorescent fixtures selected will provide equivalent light compared to the average light output of the existing metal halide fixtures. The bulb replacement cost for T-5 HO lamps compared to the existing metal halide lamps were found to be approximately equal and therefore not included in the savings calculations.

ECM #3: Lighting Controls Upgrade – Occupancy Sensors Description: Some of the lights in the school building are left on unnecessarily. In many cases the lights are left on because of the inconvenience to manually switch lights off when a room is left or on when a room is first occupied. This is common in rooms that are occupied for only short periods and only a few times per day. In some instances lights are left on due to the misconception that it is better to keep the lights on rather than to continuously switch lights on and off. Although increased switching reduces lamp life, the energy savings outweigh the lamp replacement costs. The payback timeframe for when to turn the lights off is approximately two minutes. If the lights are expected to be off for at least a two minute interval, then it pays to shut them off.
Lighting controls come in many forms. Sometimes an additional switch is adequate to provide reduced lighting levels when full light output is not needed. Occupancy sensors detect motion and will switch the lights on when the room is occupied. Occupancy sensors can either be mounted in place of a current wall switch, or on the ceiling to cover large areas. The U.S. Department of Energy sponsored a study to analyze energy savings achieved through various types of building system controls. The referenced savings is based on the “Advanced Sensors and Controls for Building Applications: Market Assessment and Potential R&D Pathways,” document posted for public use April 2005. The study has found that commercial buildings have the potential to achieve significant energy savings through the use of building controls. The average energy savings are as follows based on the report:
• Occupancy Sensors for Lighting Control 20% - 28% energy savings.
Savings resulting from the implementation of this ECM for energy management controls are estimated to be 20% of the total light energy controlled by occupancy sensors and daylight sensors (The majority of the savings is expected to be after school hours when rooms are left with lights on) This ECM includes installation of ceiling or switch mount sensors for individual offices, classrooms, large bathrooms, and libraries. Sensors shall be manufactured by Sensorswitch, Watt Stopper or equivalent. The Investment Grade Lighting Audit Appendix of this report includes the summary of lighting controls implemented in this ECM and outlines the proposed controls, costs, savings, and payback periods. The calculations adjust the lighting power usage by the applicable percent savings for each area that includes lighting controls. Energy Savings Calculations:

ECM #4: Computer Monitor Replacement Description: There are a total 126 computers in the classrooms and offices with CRT desktop monitors. These computer monitors are outdated and have several disadvantages such as; significantly increased higher energy consumption, uses large amount of desk space, poor picture quality, distortions and flickering image, secular glare problems, and high weight, and electromagnetic emissions. Many of the drawbacks are difficult to quantify except for the energy use. CRT monitors use considerably more energy than an alternative flat panel LCD monitor. Replacement of the existing CRT monitors with LCD monitors saves considerable energy as well as provides other ergonomic benefits as well. Based on the site survey it was noted that a number of the computers were left on and they may be allowed to run 24 / 7. Some of the monitors were left in screen saver mode, which is deceiving since this mode only saves the computer screen from image burn in, however it does not save on energy consumption. The average operating hours for all computers and monitors is estimated based on the site survey observations. Energy consumption of computer monitors is based on manufacture’s specifications. This ECM includes replacement of all existing CRT monitors with LCD flat panel monitors throughout the building. Installation costs were neglected for this ECM with the intention that this ECM would be replaced by the facility IT technicians. The calculations are based on the following operating assumptions: Energy Savings Calculations: # of CRT Monitors: 128 Weeks per Yr: 42 Hrs per Week: 60 (12 hrs per day estimated average)

ECM #5: Demand Controlled Ventilation Demand Controlled Ventilation (DCV) is a means to provide active, zone level control of ventilation for spaces within a facility. The basic premise behind DCV is monitoring indoor CO2 levels versus outdoor CO2 levels in order to provide proper ventilation to the spaces within the facility as well as saving costly dollars treating unconditioned ventilation air. Carbon dioxide ventilation control or demand controlled ventilation (DCV) allows for the measurement and control of outside air ventilation levels to a target cfm/person ventilation rate in the space (i.e., 15 cfm/person) based on the number of people in the space. It is a direct measure of ventilation effectiveness and is a method whereby buildings can regain active and automatic zone level ventilation control, without having to open windows. The fixed ventilation approach depends on a set-it-and-forget-it methodology that is completely unresponsive to changes in the way spaces are utilized/occupied or how equipment is maintained. A DCV system utilizes various control algorithms to maintain a base ventilation rate. The system monitors space CO2 levels and the algorithm automatically adjusts the outdoor and return air dampers to provide the quantity of outdoor air to maintain the required CO2 level in the space. System designs are normally designed for maximum occupancy and the ventilation rates are designed for this (maximum) occupancy. In areas where occupancy swings are prevalent there is ample opportunity to reduce outdoor air quantity to satisfy the needs of the actual number of occupants present. By installing the DCV controls, energy savings are realized by the reduced quantities of outdoor air that do not require heating and cooling energy from the steam and chilled water plants. There are packaged rooftop air conditioning units (RTUs) providing heating and air conditioning to the cafeteria, stage area, north hall, gymnasium, library, south hall, classrooms #157, 147, and 149. When operating, these units provide minimum amount of outside air to the space. The outside air volume is typically based on the maximum occupancy of the space conditioned. When a given space is not fully occupied the outside air quantity delivered to the space is greater than the amount needed for adequate ventilation. This ECM includes the installation of CO2 sensors integrated into a demand control ventilation system, for the units mentioned above. This system allows the air handling unit to respond to changes in occupancy and therefore reduce the amount of outside air that has to be conditioned. Outside air accounts for a large portion of the energy consumption in the HVAC system, especially in high occupancy spaces. The components required for the demand control ventilation system installation include damper actuators, Variable Frequency Drives, CO2 sensors, wiring, Energy Management System equipment expansion and programming. Each occupied zone would require minimum one CO2 sensor installed to monitor occupancy levels. Often heating and air conditioning units switch to occupied mode several hours before the actual occupancy in order to provide pre-heating or pre-cooling of the space. Energy savings achieved through “Demand Control Ventilation” is calculated based on actual occupancy of the spaces and the hours the units are in occupied mode. Energy Savings Calculations:

Currently, the units are monitored and controlled by the building management system. It is recommended to replace older unit ventilators with modern unit unit ventilators with built-in energy recovery wheels. The advantage of this setup is the utilization of the energy recovery system to recover the energy in the exhaust air in order to reduce the heating and cooling demand of the classrooms. This ECM replaces existing 32 older unit ventilators with new unit ventilators with high efficiency R410A compressors, hot water heating coils and built-in energy recovery wheels. The basis for this ECM is Airedale Classmate CHX-4&5 model unit ventilator with 450 CFM Energy Recovery ventilators and higher EER cooling modules. Energy Savings Calculations: The energy savings calculations are based improved full load cooling efficiency of the unit ventilators and the energy recovery capacity of the recovery wheels. There will be no heating energy savings due to the upgrade since both existing units and new units utilize hot water coils. Cooling energy consumption, electric demand and operation cost of each unit are calculated using the formulas below:

ECM #7: Water Cooled Chiller Installation Description: Cooling for the Mount Prospect Elementary School is achieved by unit ventilators in the classrooms with direct expansion cooling and packaged HVAC equipment in the offices and meeting areas. Air cooled cooling equipment uses more energy than water cooled systems. Therefore, water cooled chillers provide significant energy savings over air cooled unitary equipment due to the efficiency increase. The average full load efficiency of the existing air cooled unitary equipments is approximately 9 EER, which corresponds to 1.33 KW/Ton. The efficiency of a water cooled chiller is approximately 0.38 KW/Ton (IPLV). The ancillary pumping energy and cooling tower fan energy is approximately 0.14 KW/Ton. Cooling tower make-up water requirements is estimated to be 2.5 Gal/Ton-Hr. This ECM includes the installation of two new water cooled chillers to provide chilled water to the existing rooftop HVAC units and the unit ventilators. The equipment includes an outdoor water-cooled chiller package with condenser water pumps, a cooling tower, chilled water pumps and chilled water coils for the rooftop units and the unit ventilators. The installation also includes all associated piping, labor, and controls. The ECM is based on two (2) 150 Ton McQuay model number WMC 150D Magnitude™ Water-Cooled Frictionless Centrifugal Chillers or equivalent. Sizing indicated within the calculation of this ECM is based on replacement of the total existing equipment capacity. The owner should have a Professional Engineer verify heating and cooling loads to verify actual building cooling requirements. Parameters:

ECM #8: Install NEMA Premium® Efficiency Motors Description: The improved efficiency of the NEMA Premium® efficient motors is primarily due to better designs with use of better materials to reduce losses. Surprisingly, the electricity used to power a motor represents 95 % of its total lifetime operating cost. Because many motors operate continuously 24 hours a day, even small increases in efficiency can yield substantial energy and dollar savings. The electric motors driving the primary hot water pumps in the main boiler room are candidates for replacing with premium efficiency motors. These standard efficiency motors run considerable amount of time over a year. This energy conservation measure replaces existing electric motors over 5 HP or more with NEMA Premium® efficiency motors. NEMA Premium® is the most efficient motor designation in the marketplace today.

ECM #9: Install Pump VFD’s Description: The packaged rooftop air conditioners and the unit ventilators are utilizing a constant volume pumping design. The units have 3-way control valves which allow continuous flow through the piping loop throughout the building. As a result the water loop pumps must provide full power output to circulate the water through all unit ventilators and the rooftop units continuously. 2-way control valves provide flow through the heat exchanger equipment only when there is a call for heating or cooling, unlike 3-way control valves that allow constant flow of the water loop. 3-way control valves require full pumping energy continuously, while 2-way control valves allow the system to reduce flow when it is not needed. This measure includes capping off the bypass port on the 3-way control valves which effectively turns the valves into “2-way” control valves. When the unit ventilator is not calling for heating, the control valve closes reducing overall flow of the system. Variable frequency drives allow the pumps to slow down in response to a reduction in overall system flow. The reduction in operating flow allows the pumps to reduce energy consumption for all hours that the heating system is not at its peak load. This ECM includes the installation of Variable Frequency Drives on the two (2) existing 15 horsepower hot water pumps in conjunction with piping modifications at each unit ventilator and the rooftop unit to cap off the bypass port on the 3-way control valves. The VFD’s would be controlled by a differential pressure sensor in the water loop to measure demand for water. The furthest unit ventilators from the loop pumps would remain as 3-way control valves (constant flow) to eliminate dead heading potential. This ECM also includes replacement of the existing pump motors with inverter duty motors that meet NEMA Premium Efficiency Standard, which also helps to reduce energy consumption. Energy and cost savings calculations are based on calculation software “PumpSave v4.2,” provided by ABB. The PumpSave calculation software is used to estimate the pumping energy for variable speed pump systems. The boiler water loop pump operation is estimated to be 4,380 Hrs per year since this system is used for about 6 months total. The pump flow, HD, and resultant energy are calculated based on the existing pump horse power installed. Energy Savings Calculations:

V. ADDITIONAL RECOMMENDATIONS The following recommendations include no cost/low cost measures, Operation & Maintenance (O&M) items, and water conservation measures with attractive paybacks. These measures are not eligible for the Smart Start Buildings incentives from the office of Clean Energy but save energy none the less.
A. Chemically clean the condenser and evaporator coils periodically to optimize efficiency. Poorly maintained heat transfer surfaces can reduce efficiency 5-10%.
B. Maintain all weather stripping on windows and doors.
C. Clean all light fixtures to maximize light output to avoid use of task lighting.
D. Provide more frequent air filter changes to decrease overall system power usage and maintain better IAQ.
E. Turn off computers when not in use. Ensure computers are not running in screen saver mode which saves the monitor screen not energy.
F. Ensure outside air dampers are functioning properly and only open during occupied mode.
It was noted at the site survey that the HVAC systems in several rooms were not controlling temperature correctly. The result of the controls issues causes space temperatures to become uncomfortable and drastic measures such as opening windows on extremely cold days. This type of issue requires a whole system controls evaluation for the building to determine where control problems are taking place. Based on information provided by the operations personnel, there are several control systems within the building which operate different section or systems throughout the building. In addition, multiple control vendors are utilized to maintain the control systems. The use of multiple control systems and control vendors to support the systems will very likely cause issues with the overall function of the building. The systems and controls throughout the district represent a large potential “energy leak” throughout the building. It is recommended to quantify the control system points and verify their proper operation through Retro-Commissioning. Retro-Commissioning allows facility owners to re-establish the operation of the HVAC systems back to the original specifications. A third party evaluation is highly recommended to review the controls of the systems and provide insight into the corrections needed. It is also recommended to consider the renovation of all control systems into one central control system to avoid the overlap and communication gap when utilizing multiple control systems. This renovation should be consistent across all facility throughout Bernards Public Schools to maximize the benefit of central controls.

ECM #1: Lighting Upgrade – Interior spaces Description: The majority of the interior lighting throughout Oaks Elementary School is provided with fluorescent fixtures with older generation, 700 series 32W T8 lamps and electronic ballasts. Although 700 series T8 lamps are considered fairly efficient, further energy savings can be achieved by replacing the existing T8 lamps with new generation, 800 series 28W T8 lamps without compromising light output. CEG recommends, re-lamping all of the fixtures with 28W T8 lamps. In addition, some of the storage areas, locker room and gym areas, offices, auditorium, classrooms, restrooms and kitchen areas still have a variety of older fluorescent fixtures with magnetic ballasts and incandescent lamps. It is recommended to retrofit or replace all of the older fluorescent fixtures and the incandescent lights in these areas with high efficiency fluorescent T8 or T5 fixtures with electronic ballasts or compact fluorescent lamps. This ECM includes re-lamping of the existing fluorescent fixtures with 800 series, 28W T8 lamps. The ECM also includes retrofit of all older fluorescent fixtures with T8 or T5 fluorescent fixtures with electronic ballasts in the building. The new, energy efficient T8 fixtures will provide adequate lighting and will save on electrical costs due to better performance of the lamp and ballasts. Energy Savings Calculations: The Investment Grade Lighting Audit Appendix outlines the hours of operation, proposed retrofits, costs, savings, and payback periods for each set of fixtures in the each building. Rebates and Incentives: There are no incentives available from NJ Smart Start® Program for the retrofits in this ECM. Replacement and Maintenance Savings: There is no significant replacement and maintenance savings due to implementation of this ECM.

ECM #2: Lighting Upgrade – Gym & Auditorium Description: The Auditorium and Gymnasium at Oak Elementary School utilizes 400W metal halide fixtures for its lighting. Metal halide bulbs provide a reasonably efficient option for bay lighting however a few draw-backs that are common. Metal halide fixtures often have poor overall efficacy which limits the amount of light actually leaving the fixture. Also metal halide bulbs require a significant warm-up period and even longer cool down period eliminating the potential for occupancy sensors frequent switching. This symptom encourages the gymnasium lighting to be left on continuously during the day. Another drawback is the reduced lumen output (Lumen Maintenance) of the metal halide bulb over its life time. Average bulb output or “mean lumens,” is approximately 25% less than the bulb’s initial lumens for typical metal halide lamps. In addition the most rapid rate of light output decline is during the beginning of its life, approximately 15-20% light loss within the first 20% of its rated life. It is important to note that the light loss has no savings in energy used; therefore the overall light efficiency is continuously decreasing with age. The final drawback is the light quality or Color Rendering Index (CRI). Typical values for metal halide bulbs is 65, which is a measure of how close the light is to true “full spectrum” light produced by sunlight or incandescent lighting. Metal halide bulbs also show noticeable color shifting when the bulb is reaching the end of its life. Utilizing fluorescent fixtures in low and high bay spaces is a superior option over metal halide fixtures in all areas described above. Although metal halide fixtures provide light very efficiently at the start of the bulb life, the average efficiency over the life is below that of fluorescent fixtures. This ECM includes replacement of each of the existing gymnasium high bay metal halide light fixtures with T5HO fixtures with reflective lenses. The retrofit for the metal halide fixtures includes a one for one fixture replacement. The fluorescent fixtures selected will provide equivalent light compared to the average light output of the existing metal halide fixtures. The bulb replacement cost for T-5 HO lamps compared to the existing metal halide lamps were found to be approximately equal and therefore not included in the savings calculations.

ECM #3: Lighting Controls Upgrade – Occupancy Sensors
Bernards Public Schools – Oak Street School Energy Audit
Concord Engineering Group, Inc. 9C10088 April 15, 2011– FINAL Page 19 of 31
Description: Some of the lights in the school building are left on unnecessarily. In many cases the lights are left on because of the inconvenience to manually switch lights off when a room is left or on when a room is first occupied. This is common in rooms that are occupied for only short periods and only a few times per day. In some instances lights are left on due to the misconception that it is better to keep the lights on rather than to continuously switch lights on and off. Although increased switching reduces lamp life, the energy savings outweigh the lamp replacement costs. The payback timeframe for when to turn the lights off is approximately two minutes. If the lights are expected to be off for at least a two minute interval, then it pays to shut them off.
Lighting controls come in many forms. Sometimes an additional switch is adequate to provide reduced lighting levels when full light output is not needed. Occupancy sensors detect motion and will switch the lights on when the room is occupied. Occupancy sensors can either be mounted in place of a current wall switch, or on the ceiling to cover large areas. The U.S. Department of Energy sponsored a study to analyze energy savings achieved through various types of building system controls. The referenced savings is based on the “Advanced Sensors and Controls for Building Applications: Market Assessment and Potential R&D Pathways,” document posted for public use April 2005. The study has found that commercial buildings have the potential to achieve significant energy savings through the use of building controls. The average energy savings are as follows based on the report:
• Occupancy Sensors for Lighting Control 20% - 28% energy savings.
Savings resulting from the implementation of this ECM for energy management controls are estimated to be 20% of the total light energy controlled by occupancy sensors and daylight sensors (The majority of the savings is expected to be after school hours when rooms are left with lights on) This ECM includes installation of ceiling or switch mount sensors for individual offices, classrooms, large bathrooms, and libraries. Sensors shall be manufactured by Sensorswitch, Watt Stopper or equivalent. The Investment Grade Lighting Audit Appendix of this report includes the summary of lighting controls implemented in this ECM and outlines the proposed controls, costs, savings, and payback periods. The calculations adjust the lighting power usage by the applicable percent savings for each area that includes lighting controls. Energy Savings Calculations:

ECM #4: Computer Monitor Replacement Description: The computers throughout the school utilize a mixture of CRT computer monitors and LCD computer monitors. The CRT computer monitors within the offices and classrooms are outdated and have several disadvantages such as; significantly increased energy consumption, uses large amount of desk space, poor picture quality, distortions and flickering image, secular glare problems, high weight, and electromagnetic emissions. Many of these drawbacks are difficult to quantify except for the energy use. CRT monitors use considerably more energy than an alternative flat panel LCD monitor. Replacement of the existing CRT monitors with LCD monitors saves considerable energy as well as provides other ergonomic benefits. Based on the site survey it was noted that there are 29 LCD monitor and 97 CRT monitors. Some of the monitors were left in screen saver mode, which only saves the computer screen from image burn in, however it does not save on energy consumption. The average operating hours for all computers and monitors is estimated based on the site survey observations. Energy consumption of computer monitors is based on averages for power usage of various computer monitors. This ECM includes replacement of all existing CRT monitors with LCD flat panel monitors throughout the facility. Installation costs were neglected for this ECM with the intention that this ECM would be replaced by the school district. The calculations are based on the following operating assumptions: Energy Savings Calculations: No. of CRT Monitors: 97 Operating Weeks per Yr: 29 Hrs per Week: 60 (12 hrs per day estimated average)

ECM #5: Demand Controlled Ventilation Demand Controlled Ventilation (DCV) is a means to provide active, zone level control of ventilation for spaces within a facility. The basic premise behind DCV is monitoring indoor CO2 levels versus outdoor CO2 levels in order to provide proper ventilation to the spaces within the facility as well as saving costly dollars treating unconditioned ventilation air. Carbon dioxide ventilation control or demand controlled ventilation (DCV) allows for the measurement and control of outside air ventilation levels to a target cfm/person ventilation rate in the space (i.e., 15 cfm/person) based on the number of people in the space. It is a direct measure of ventilation effectiveness and is a method whereby buildings can regain active and automatic zone level ventilation control, without having to open windows. The fixed ventilation approach depends on a set-it-and-forget-it methodology that is completely unresponsive to changes in the way spaces are utilized/occupied or how equipment is maintained. A DCV system utilizes various control algorithms to maintain a base ventilation rate. The system monitors space CO2 levels and the algorithm automatically adjusts the outdoor and return air dampers to provide the quantity of outdoor air to maintain the required CO2 level in the space. System designs are normally designed for maximum occupancy and the ventilation rates are designed for this (maximum) occupancy. In areas where occupancy swings are prevalent there is ample opportunity to reduce outdoor air quantity to satisfy the needs of the actual number of occupants present. By installing the DCV controls, energy savings are realized by the reduced quantities of outdoor air that do not require heating and cooling energy from the steam and chilled water plants. The split rooftop unit serving the cafeteria and four (4) rooftop units serving the gymnasium are standard air conditioning systems with constant minimum outside air setup. When these units are on occupied mode, the outside air dampers open and remain open until the units switch to unoccupied mode. The outside air volume quantity is typically based on the maximum occupancy of the space conditioned. When a given space is not fully occupied the outside air quantity delivered to the space is greater than the amount actually needed for adequate ventilation, which results in waste of heating or air conditioning energy. This ECM includes the installation integrated demand control ventilation systems with CO2 sensors, for the unit mentioned above. This system allows the air handling unit to respond to changes in occupancy and therefore reduce the amount of outside air that has to be conditioned. Outside air accounts for a large portion of the energy consumption in the HVAC system, especially in high occupancy spaces. The U.S. Department of Energy sponsored a study to analyze energy savings achieved through various types of building system controls. The referenced savings is based on the “Advanced Sensors and Controls for Building Applications: Market Assessment and Potential R&D Pathways,” document posted for public use April 2005. The study has found that commercial buildings have the potential to achieve significant energy savings through the use of building controls. The average energy savings are as follows based on the report:
• Demand Control Ventilation - 10% - 15%.

Energy savings achieved through “Demand Control Ventilation” average 10%-15%. Savings resulting from the implementation of this ECM for energy management controls are estimated to be 15% of the total HVAC energy cost for this system. The components included to install for a demand control ventilation system include damper actuators, Variable Frequency Drives, CO2 sensors, wiring, Energy Management System equipment expansion and programming. Each occupied zone would require minimum one CO2 sensor installed to monitor occupancy levels.

ECM #6: Air Conditioning Unit Upgrades
Description:
Oak Street Elementary is air conditioned by split system AC units and packaged rooftop units. The majority of the units at the elementary schools are in fair condition and near the end of their useful life of 15 years, which is defined by ASHRAE. The units currently installed are inefficient compared to modern equipment and can be replaced with new high efficiency units. New air conditioners provide higher full load and part load efficiencies due to advances in inverter motor technologies, heat exchangers and refrigerants. This ECM includes one-for-one replacement of the older air conditioning units with new higher efficiency systems. It is recommended to fully evaluate the capacity needed for all new systems prior to moving forward with this ECM. A summary of the unit replacements for this ECM can be found in the table below:

V. ADDITIONAL RECOMMENDATIONS The following recommendations include no cost/low cost measures, Operation & Maintenance (O&M) items, and water conservation measures with attractive paybacks. These measures are not eligible for the Smart Start Buildings incentives from the office of Clean Energy but save energy none the less.
A. Chemically clean the condenser and evaporator coils periodically to optimize efficiency. Poorly maintained heat transfer surfaces can reduce efficiency 5-10%.
B. Maintain all weather stripping on windows and doors.
C. Clean all light fixtures to maximize light output to avoid use of task lighting.
D. Provide more frequent air filter changes to decrease overall system power usage and maintain better IAQ.
E. Turn off computers when not in use. Ensure computers are not running in screen saver mode which saves the monitor screen not energy.
F. Ensure outside air dampers are functioning properly and only open during occupied mode.
It was noted at the site survey that the HVAC systems in several rooms were not controlling temperature correctly. The result of the controls issues causes space temperatures to become uncomfortable and drastic measures such as opening windows on extremely cold days. This type of issue requires a whole system controls evaluation for the building to determine where control problems are taking place. Based on information provided by the operations personnel, there are several control systems within the building which operate different section or systems throughout the building. In addition, multiple control vendors are utilized to maintain the control systems. The use of multiple control systems and control vendors to support the systems will very likely cause issues with the overall function of the building. The systems and controls throughout the district represent a large potential “energy leak” throughout the building. It is recommended to quantify the control system points and verify their proper operation through Retro-Commissioning. Retro-Commissioning allows facility owners to re-establish the operation of the HVAC systems back to the original specifications. A third party evaluation is highly recommended to review the controls of the systems and provide insight into the corrections needed. It is also recommended to consider the renovation of all control systems into one central control system to avoid the overlap and communication gap when utilizing multiple control systems. This renovation should be consistent across all facility throughout Bernards Public Schools to maximize the benefit of central controls.

II. FACILITY DESCRIPTION
The 297,152 SF Ridge High School is a two story facility comprised of classrooms, library, computer room, media center, cafeteria, kitchen, four gymnasiums, administration offices, auditorium, restrooms, two boiler rooms, custodial spaces and storage spaces. The School was built in 1961 with additions added in 1966, 1982, 1999 and 2008. The additions to the building include the 600 wing and gymnasium as well as the media center in the 1966 & 1982 additions. In 1999 the two story 500 wing was added. In 2008 the two story 700 wing was added in addition to the new auditorium and new gym.
Building Profile
The hours of operation for the school students and teachers are between 8:30 AM and 2:30 PM on the weekdays. The facility remains occupied for after school sports and other programs unit 6:00 PM. Custodial services are performed between the hours of 6:00 PM and 11:00 PM. The facility is closed on weekends with the exception of sporting events. The student enrollment at the high school is approximately 1603 students and 204 teachers.
Building Envelope
The facility exterior construction is primarily CMU block with 4-inch brick façade. Portions of the original building classroom wings utilized curtain wall systems with glass windows and insulated metal panels. Insulation within the original building is estimated to consist of an air space between the block wall and brick façade. The construction in the new additions is estimated to have 1”-2” of rigid insulation within the exterior wall. The roof on the building is a flat built up style roof with tar coating and crushed stone on top. The new additions including a newer style built up flat roof with rigid insulation (estimated 2” minimum) and a black rubber roof membrane. The windows throughout the facility are single pane aluminum framed windows in the original building and double pane aluminum frame windows in the building additions. The older windows appear to be in fair to good condition. The windows in the newer sections are in good condition and appear to be providing a tight weather barrier. Blinds for the windows integral to the double pane window system and appear to be in good working order.
HVAC Systems
Heating is provided by two central hot water heating systems. The original building boiler room provides heat for the majority of the school’s terminal hydronic heating equipment with the exception of the auditorium and 700 wing. The new boiler plant services the new auditorium and 700 wing terminal equipment.
The original boiler plant is comprised of two cast iron sectional style boilers. Each of the Weil McLain 94 Series boilers has an input capacity of 5,950 MBH. These boilers provide heating hot water to baseboards, unit ventilators, and heating and ventilation units throughout the school. The boilers are in good condition and appear to be maintained. The original boiler room also utilizes four (4) Patterson Kelly Thermific series modular style boilers. Each of the four modular boilers have an input capacity of 1,700 MBH. The modular boilers are piped in a primary
Bernards Public Schools – Ridge High School Energy Audit
Concord Engineering Group, Inc. 9C10088 April 15, 2011– FINAL Page 8 of 60
secondary configuration. Each modular boiler utilizes a dedicated primary hot water pump. These boilers are in good condition. The large cast iron boilers utilize two 20 HP constant speed end suction pumps for hot water distribution. The end suction pumps are in good to fair condition. The 4 modular style boilers utilize two 25 HP constant speed inline pumps for hot water distribution. There are some signs of leakage around the pump housing and deterioration with the inline pumps. The inline pumps are in fair condition.
The newer boiler room is comprised of four condensing boilers made by Aerco. Each boiler has an input capacity of 2,000 MBH. The boiler water is circulated through the building by two end suction constant speed pumps driven by 15 HP premium efficiency motors. The new boiler room and equipment within the new boiler plant is in excellent condition.
Terminal heating equipment consists of unit ventilators made by Nesbitt in combination with hydronic baseboard heat. These units serve the classrooms throughout the school and the cafeteria. The unit ventilators in the original portion as well as the older additions, appear to be in poor condition. The unit ventilators are controlled by the building pneumatic system. In many cases these controls are not functioning correctly due to leaks in the system or failure of the control valves resulting in lack of temperature control. As a result of these issues, the poorly controlled classrooms as well as other spaces have windows open in the winter to maintain comfortable temperatures.
The newer classrooms in the building addition utilize vertical style packaged heating and cooling units made by Airedale. Each classroom has a dedicated packaged heating and cooling unit with overhead ductwork for air distribution. The newer Airedale units are installed in the 500 wing and 700 wing. Heat is provided by hot water heating coils fed from the central boiler plant. Cooling is packaged within the unit and heat is rejected through an exterior wall louver. Each unit is installed within an enclosed cabinet in the corner of the classroom. These units can be removed from the cabinet for service. The packaged Airedale units are loud and seem to be in fair / poor condition despite their recent installation within the building additions. There was a lack of temperature control evident within the new sections of the building. The new section of the building is controlled with modern electronic controls. It is unknown if the temperature control issues is a result of the control components or the central control system.
The building also utilizes large heating and ventilation units with hot water coils that provide heat for the large open areas such as the old gymnasiums. These units appear to be original to the building and in poor condition. The H&V units within the gymnasium utilize the pneumatic control system with 3-way control valves.
In addition to the central heating system, several spaces utilized packaged rooftop heating and cooling units for heat with gas fired heat exchangers or hot water heating coils. The packaged units provide heat for various spaces such as; classrooms in the 200 wing, 300 wing, 400 wing, 600 wing, as well as the computer rooms, media center, central offices, cafeteria, new gymnasium, locker rooms, and the new auditorium. The majority of the packaged units are made by AAON, Lennox, McQuay. The units range from new and excellent condition to old and poor condition.

Cooling is provided for several spaces within the school. All of the new addition classrooms have air conditioning units provided by the package Airedale units. Packaged rooftop units with air conditioning provide cooling for additional spaces such as; various classrooms, the library, media center, computer rooms, media center, central offices, cafeteria, new gymnasium, locker rooms, and the new auditorium. The remaining cooling throughout the building is provided by split systems. The split system AC units provide cooling for other classrooms throughout the building as well as additional office areas and IT closest throughout the school. These units include ductless split systems made by Sanyo and Mitsubishi Electric as well as standard split systems made by Airedale, Trane, and Comfort Aire. These units vary in age and condition.
Exhaust System
Exhaust is provided by roof top mounted exhaust fans primarily located over the hallways. The exhaust fans are utilized to relieve the excess building pressure due to outside air brought in through the unit ventilators and packaged rooftop units. It is unknown if these units operate based on a time schedule and shut down in occupied mode. Bathrooms and toilet rooms are exhausted through smaller rooftop exhaust fans typically interlocked with the bathroom wall switch.
The kitchen includes a 4FT x 22FT commercial exhaust hood, which provides exhaust for cooking equipment. The kitchen hood is manually controlled with a wall switch. The exhaust fan is running based on the needs from the kitchen staff. It was noted that the kitchen exhaust fan in was running well into the after school hours (6:30 PM). At the time of the survey the kitchen was shut down and locked which indicates that the exhaust system would run 24 hours per day. It is estimated that the exhaust fan runs 12 hrs per day at a minimum.
HVAC System Controls
The building HVAC system is a combination of an old pneumatic system that controls the older unit ventilators and H&V units, and newer electronic controls that control the classroom heating and cooling units as well as the newer rooftop equipment in the building additions. The pneumatic control system is in poor condition and in many spaces, significantly lacks in proper temperature control. It was noted that the DDC central control systems also provide poor control of space temperature in several instances. Communication errors, control device failures, and software issues are potential causes for the lack of proper control.
The terminal units throughout the building hot water system is controlled by a combination of two way control valves and three way control valves. Unit ventilators appear to all utilize two way control valves and the larger H&V units as well as rooftop units utilize 3-way control valves. In this scheme, the hot water pumps are not controlled and run at constant speed. Excess water flow in low load conditions is bypassed throughout the building 3-way control valves in lieu of slowing the pumps down.
Domestic Hot Water
Domestic hot water is provided to the school by two domestic hot water systems. The original boiler room utilizes a large storage tank in conjunction with a dedicated domestic boiler made by

AO Smith. The domestic hot water is circulated throughout the building by a small domestic hot water circulation pump. The domestic hot water systems appears to be recently replaced and in excellent condition. The new boiler room utilizes a packaged 125 gallon domestic hot water boiler made by TurboPower Gas. Domestic hot water is distributed by a small domestic hot water circulation pump. The domestic hot water boiler is in excellent condition.
Lighting Typical lighting throughout school is fluorescent tube lay-in fixtures with T-8 lamps and electronic ballasts. Some of the storage rooms and closets including the boiler room is lit with a mixture of incandescent lamps and compact fluorescent lamps. The older gyms are lit with high bay metal halide fixtures and high bay T-8 fixtures with reflectors. The new gym is lit with high bay metal halide fixtures. The building exterior is lit with high pressure sodium fixtures and metal halide flood lights. Lighting throughout the building is controlled by manual wall switches. There are a few select rooms that are controlled with occupancy sensors.

ECM #1: Lighting Upgrade – Interior spaces Description: The majority of the interior lighting throughout Ridge High School is provided with fluorescent fixtures with older generation, 700 series 32W T8 lamps and electronic ballasts. Although 700 series T8 lamps are considered fairly efficient, further energy savings can be achieved by replacing the existing T8 lamps with new generation, 800 series 28W T8 lamps without compromising light output. CEG recommends, re-lamping all of the fixtures with 28W T8 lamps. In addition, some of the storage areas, locker room and gym areas, offices, auditorium, classrooms, restrooms and kitchen areas still have a variety of older fluorescent fixtures with magnetic ballasts and incandescent lamps. It is recommended to retrofit or replace all of the older fluorescent fixtures and the incandescent lights in these areas with high efficiency fluorescent T8 or T5 fixtures with electronic ballasts or compact fluorescent lamps. This ECM includes re-lamping of the existing fluorescent fixtures with 800 series, 28W T8 lamps. The ECM also includes retrofit of all older fluorescent fixtures with T8 or T5 fluorescent fixtures with electronic ballasts in the building. The new, energy efficient T8 fixtures will provide adequate lighting and will save on electrical costs due to better performance of the lamp and ballasts. Energy Savings Calculations: The Investment Grade Lighting Audit Appendix outlines the hours of operation, proposed retrofits, costs, savings, and payback periods for each set of fixtures in the each building. Rebates and Incentives: There are no incentives available from NJ Smart Start® Program for the retrofits in this ECM. Replacement and Maintenance Savings: There is no significant replacement and maintenance savings due to implementation of this ECM.

ECM #2: Lighting Upgrade – Gym C & D Description: The older Gymnasiums (C&D) at Ridge High School utilizes 400W metal halide fixtures for its lighting. Metal halide bulbs provide a reasonably efficient option for bay lighting however a few draw-backs that are common. Metal halide fixtures often have poor overall efficacy which limits the amount of light actually leaving the fixture. Also metal halide bulbs require a significant warm-up period and even longer cool down period eliminating the potential for occupancy sensors frequent switching. This symptom encourages the gymnasium lighting to be left on continuously during the day. Another drawback is the reduced lumen output (Lumen Maintenance) of the metal halide bulb over its life time. Average bulb output or “mean lumens,” is approximately 25% less than the bulb’s initial lumens for typical metal halide lamps. In addition the most rapid rate of light output decline is during the beginning of its life, approximately 15-20% light loss within the first 20% of its rated life. It is important to note that the light loss has no savings in energy used; therefore the overall light efficiency is continuously decreasing with age. The final drawback is the light quality or Color Rendering Index (CRI). Typical values for metal halide bulbs is 65, which is a measure of how close the light is to true “full spectrum” light produced by sunlight or incandescent lighting. Metal halide bulbs also show noticeable color shifting when the bulb is reaching the end of its life. Utilizing fluorescent fixtures in low and high bay spaces is a superior option over metal halide fixtures in all areas described above. Although metal halide fixtures provide light very efficiently at the start of the bulb life, the average efficiency over the life is below that of fluorescent fixtures. This ECM includes replacement of each of the existing gymnasium high bay metal halide light fixtures with T5HO fixtures with reflective lenses. The retrofit for the metal halide fixtures includes a one for one fixture replacement. The fluorescent fixtures selected will provide equivalent light compared to the average light output of the existing metal halide fixtures. The bulb replacement cost for T-5 HO lamps compared to the existing metal halide lamps were found to be approximately equal and therefore not included in the savings calculations.

ECM #3: Lighting Controls Upgrade – Occupancy Sensors Description: Some of the lights in the school building are left on unnecessarily. In many cases the lights are left on because of the inconvenience to manually switch lights off when a room is left or on when a room is first occupied. This is common in rooms that are occupied for only short periods and only a few times per day. In some instances lights are left on due to the misconception that it is better to keep the lights on rather than to continuously switch lights on and off. Although increased switching reduces lamp life, the energy savings outweigh the lamp replacement costs. The payback timeframe for when to turn the lights off is approximately two minutes. If the lights are expected to be off for at least a two minute interval, then it pays to shut them off.
Lighting controls come in many forms. Sometimes an additional switch is adequate to provide reduced lighting levels when full light output is not needed. Occupancy sensors detect motion and will switch the lights on when the room is occupied. Occupancy sensors can either be mounted in place of a current wall switch, or on the ceiling to cover large areas. The U.S. Department of Energy sponsored a study to analyze energy savings achieved through various types of building system controls. The referenced savings is based on the “Advanced Sensors and Controls for Building Applications: Market Assessment and Potential R&D Pathways,” document posted for public use April 2005. The study has found that commercial buildings have the potential to achieve significant energy savings through the use of building controls. The average energy savings are as follows based on the report:
• Occupancy Sensors for Lighting Control 20% - 28% energy savings.
Savings resulting from the implementation of this ECM for energy management controls are estimated to be 20% of the total light energy controlled by occupancy sensors and daylight sensors (The majority of the savings is expected to be after school hours when rooms are left with lights on) This ECM includes installation of ceiling or switch mount sensors for individual offices, classrooms, large bathrooms, and libraries. Sensors shall be manufactured by Sensorswitch, Watt Stopper or equivalent. The Investment Grade Lighting Audit Appendix of this report includes the summary of lighting controls implemented in this ECM and outlines the proposed controls, costs, savings, and payback periods. The calculations adjust the lighting power usage by the applicable percent savings for each area that includes lighting controls. Energy Savings Calculations:

ECM #4: Computer Monitor Replacement Description: The computers throughout the school utilize a mixture of CRT computer monitors and LCD computer monitors. The CRT computer monitors within the offices and classrooms are outdated and have several disadvantages such as; significantly increased energy consumption, uses large amount of desk space, poor picture quality, distortions and flickering image, secular glare problems, high weight, and electromagnetic emissions. Many of these drawbacks are difficult to quantify except for the energy use. CRT monitors use considerably more energy than an alternative flat panel LCD monitor. Replacement of the existing CRT monitors with LCD monitors saves considerable energy as well as provides other ergonomic benefits. Based on the site survey it was noted that there are 263 LCD monitor and 186 CRT monitors. Some of the monitors were left in screen saver mode, which only saves the computer screen from image burn in, however it does not save on energy consumption. The average operating hours for all computers and monitors is estimated based on the site survey observations. Energy consumption of computer monitors is based on averages for power usage of various computer monitors. This ECM includes replacement of all existing CRT monitors with LCD flat panel monitors throughout the facility. Installation costs were neglected for this ECM with the intention that this ECM would be replaced by the school district. The calculations are based on the following operating assumptions: Energy Savings Calculations: No. of CRT Monitors: 186 Operating Weeks per Yr: 42 Hrs per Week: 60 (12 hrs per day estimated average)

ECM #5: Install New Unit Ventilators Description: The heating and air conditioning for the new additions at Ridge High School is provided by upright style Airedale unit ventilators. These unit ventilators are approximately 13 years old and near the end of expected useful service life, which is fifteen (15) years per ASHRAE. There are approximately 31 unit ventilators in the 500 wing that utilize these units. The units are packaged with 4-ton (28 units) and 6-ton (3 units) cooling capacities and hot water heating coils. Currently, the units are monitored and controlled by the building management system. It is recommended to replace older unit ventilators with modern unit ventilators with built-in energy recovery wheels. The advantage of this setup is the utilization of the energy recovery system to recover the energy in the exhaust air in order to reduce the heating and cooling demand of the classrooms. This ECM replaces 31 existing older unit ventilators with new unit ventilators with high efficiency R410A compressors, hot water heating coils and built-in energy recovery wheels. The basis for this ECM is Airedale Classmate CHX-4&5 model unit ventilator with 450 CFM Energy Recovery ventilators and higher EER cooling modules. Energy Savings Calculations: The energy savings calculations are based improved full load cooling efficiency of the unit ventilators and the energy recovery capacity of the recovery wheels. There will be no heating energy savings due to the upgrade since both existing units and new units utilize hot water coils. Cooling energy consumption, electric demand and operation cost of each unit are calculated using the formulas below:

ECM #6: Valve Blanket and Pipe Insulation
Description: The old boiler plant supplies heating hot water to the facility for heating season. The piping remains heated at approximately 180°F continuously during this period (approximately 6 months). Un-insulated piping has significant heat losses due to the exposure of the steel piping to the surrounding air. Insulated piping has a heat loss which is a small fraction of the heat loss from un-insulated piping. It was noted that significant piping within the boiler room was missing piping insulation including numerous valves throughout the system. Based on the site survey approximately 6 large diameter pipe valves / Fitting, one air separation tank, and approximately 20 feet of 8” steel pipe was not insulated. Valve blankets are designed to provide insulation value over large hydronic valves that must remain accessible. This ECM includes installation of valve blankets on all exposed boiler system valves and insulation of all un-insulated piping and exposed components within the boiler room.

ECM #7: Install Pump VFD’s Description: The packaged rooftop air conditioners, heating and ventilation units and the unit ventilators are utilizing a constant volume pumping design. The unit ventilators are equipped with 2-way control valves and the rooftop units have 3-way control valves which allow continuous flow through the piping loop throughout the building. As a result the water loop pumps must provide nearly full power output to circulate the water through all rooftop units and unit ventilators continuously. 2-way control valves provide flow through the heat exchanger equipment only when there is a call for heating or cooling, unlike 3-way control valves that allow constant flow of the water loop. 3-way control valves require full pumping energy continuously, while 2-way control valves allow the system to reduce flow when it is not needed. This measure includes capping off the bypass port on the 3-way control valves which effectively turns the valves into “2-way” control valves. When the unit is not calling for heating, the control valve closes reducing overall flow of the system. Variable frequency drives allow the pumps to slow down in response to a reduction in overall system flow. The reduction in operating flow allows the pumps to reduce energy consumption for all hours that the heating system is not at its peak load. This ECM includes the installation of Variable Frequency Drives on the four (4) existing pumps within the old boiler room as well as the two (2) existing pumps in the new boiler room. To control flow through the system, this ECM includes piping modifications at the rooftop units, H&V units, and unit ventilators to cap off the bypass port on the 3-way control valves. The VFD’s would be controlled by a differential pressure sensor in the water loop to measure demand for water (typical for each of the three pump sets). The furthest unit from the loop pumps would remain as 3-way control valves (constant flow) to eliminate dead heading potential. This ECM also includes replacement of the existing pump motors with inverter duty motors that meet NEMA Premium Efficiency Standard, which also helps to reduce energy consumption. Energy and cost savings calculations are based on calculation software “PumpSave v4.2,” provided by ABB. The PumpSave calculation software is used to estimate the pumping energy for variable speed pump systems. Two of the boiler water loop pumps operate approximately 4,320 Hrs per year since this system is used for about 6 month’s total. The pump flow, HD, and resultant energy are calculated based on the existing pump horse power installed. The calculation is based on all existing equipment to be modified to operate as 2-way control valves. Where control valves are already 2-way style, these control valves shall remain. The exact quantity of rooftop equipment with hot water coils is unknown. The operation of all equipment control valves should be verified before implementing this ECM. Energy Savings Calculations:

ECM #9: Demand Controlled Ventilation - Gymnasium Demand Controlled Ventilation (DCV) is a means to provide active, zone level control of ventilation for spaces within a facility. The basic premise behind DCV is monitoring indoor CO2 levels versus outdoor CO2 levels in order to provide proper ventilation to the spaces within the facility as well as saving costly dollars treating unconditioned ventilation air. Carbon dioxide ventilation control or demand controlled ventilation (DCV) allows for the measurement and control of outside air ventilation levels to a target cfm/person ventilation rate in the space (i.e., 15 cfm/person) based on the number of people in the space. It is a direct measure of ventilation effectiveness and is a method whereby buildings can regain active and automatic zone level ventilation control, without having to open windows. The fixed ventilation approach depends on a set-it-and-forget-it methodology that is completely unresponsive to changes in the way spaces are utilized/occupied or how equipment is maintained. A DCV system utilizes various control algorithms to maintain a base ventilation rate. The system monitors space CO2 levels and the algorithm automatically adjusts the outdoor and return air dampers to provide the quantity of outdoor air to maintain the required CO2 level in the space. System designs are normally designed for maximum occupancy and the ventilation rates are designed for this (maximum) occupancy. In areas where occupancy swings are prevalent there is ample opportunity to reduce outdoor air quantity to satisfy the needs of the actual number of occupants present. By installing the DCV controls, energy savings are realized by the reduced quantities of outdoor air that do not require heating and cooling energy from the steam and chilled water plants. There are heating and ventilation units and packaged rooftop air conditioning units (RTUs) providing heating and air conditioning to the Old and New Gymnasiums. When operating, these units provide minimum amount of outside air to the space. The outside air volume is typically based on the maximum occupancy of the space conditioned. When a given space is not fully occupied the outside air quantity delivered to the space is greater than the amount needed for adequate ventilation. This ECM includes the installation of CO2 sensors integrated into a demand control ventilation system, for the units mentioned above. This system allows the air handling unit to respond to changes in occupancy and therefore reduce the amount of outside air that has to be conditioned. Outside air accounts for a large portion of the energy consumption in the HVAC system, especially in high occupancy spaces. The components required for the demand control ventilation system installation include damper actuators, Variable Frequency Drives, CO2 sensors, wiring, Energy Management System equipment expansion and programming. Each occupied zone would require minimum one CO2 sensor installed to monitor occupancy levels. Often heating and air conditioning units switch to occupied mode several hours before the actual occupancy in order to provide pre-heating or pre-cooling of the space. Energy savings achieved through “Demand Control Ventilation” is calculated based on actual occupancy of the spaces and the hours the units are in occupied mode. Energy Savings Calculations:

ECM #10: Condensing Boiler Installation Description: Space heating for the perimeter offices and classrooms in the majority of the school is provided with unit ventilators and cabinet heaters with hot water coils and hot water radiators. The sources of hot water for these equipments are two (2) sectional hot water boilers and four (4) smaller modular hot water boilers located in the old boiler room and two (2) condensing hot water boilers in the new addition boiler room. Two (2) of the boilers are 4.75 MMBH (106 BTU/H) Weil McLain standard efficiency, sectional cast iron hot water boilers. These boilers are in fair condition and they are over 50 years old, which is well beyond their useful life of 30 years per ASHRAE. Typically, standard (non-condensing) boilers provide lower than nominal efficiency compared to condensing boilers. Standard boilers suffer further efficiency losses at part load operating conditions mainly due to limitations in the reduction of the flue gas temperature. Current average combustion efficiency of each boiler is estimated to be 75% due to standard non-condensing boiler technology, limited turn down ratio, cycling losses and outdated design and controls. A new condensing boiler could substantially improve the operating efficiency of the heating system of the building. Condensing boiler’s peak efficiency tops out at 99% depending on return water temperature. CEG recommends replacing the two (2) Weil McLain boilers with condensing hot water boilers to provide building with heating throughout the year. The annual average operating efficiency of the proposed boiler set is expected to be 90%, which gives the heating system a 15% increase in efficiency. This ECM is based on variable supply water temperature adjusted based on outdoor temperature. This ECM includes installation of three (3) new condensing gas fired boilers to replace two (2) existing hot water boilers based on following summary.

Energy Savings Calculations: Currently there are multiple boilers and gas fired rooftop units on the building gas meter. The boilers’ gas usage is not separately metered. Therefore, annual energy consumption of the boilers has to be estimated. In this calculation, it is assumed that the energy consumption of the boilers will be in proportion with the ratio of the total heating capacity of each equipment. First, domestic hot water usage is estimated and subtracted from the total usage in order to estimate the net natural gas usage for space heating. Current total hot water usage can be found in the table below:

ECM #11: Install NEMA Premium® Efficiency Motors Description: The improved efficiency of the NEMA Premium® efficient motors is primarily due to better designs with use of better materials to reduce losses. Surprisingly, the electricity used to power a motor represents 95 % of its total lifetime operating cost. Because many motors operate continuously 24 hours a day, even small increases in efficiency can yield substantial energy and dollar savings. The electric motors driving the hot water pumps in the old boiler room and supply fans in some of the rooftop equipment are candidates for replacing with premium efficiency motors. These standard efficiency motors run considerable amount of time over a year. This energy conservation measure replaces existing electric motors over 5 HP or more with NEMA Premium® efficiency motors. NEMA Premium® is the most efficient motor designation in the marketplace today.

ECM #12: Commercial Kitchen Exhaust Hood Controls Description: The kitchen in this facility is equipped with a large commercial kitchen exhaust hood providing exhaust for the cooking equipment. The estimated total kitchen exhaust from the hoods is 8,800 CFM powered by an estimated total 6 HP of exhaust and makeup air fans. The kitchen make-up air units provide heated air to replace all the air exhausted through the exhaust hood. This system operates based on manual switches located in the kitchen. Currently the facility provides 1 meal per day. The installation of kitchen exhaust controls would significantly reduce the total kitchen exhaust and make-up air quantity. The conditioned make up air and exhausted air savings are achieved by monitoring the exhaust hoods and exhaust based on the actual use of the kitchen equipment. Temperature sensors and optical lasers monitor the heat and smoke production at each exhaust hood to reduce the exhaust and make-up airflow based on the need of the kitchen equipment. This ECM includes installation of kitchen exhaust controls for the main kitchen exhaust hood and VFD’s for the constant volume exhaust fans. The hoods would be retrofitted with temperature and laser sensors to monitor the activity of each of all equipment installed below the hoods. The work involves installing a Melink Kitchen Hood Variable Air Volume Controller; variable frequency drive on the kitchen hood exhaust fan; and turn off all the kitchen hood exhaust systems when the kitchen is closed. When the cooking appliances are turned on, the hood exhaust fan speed will increase based on the hood exhaust temperature. During heavy cooking, the kitchen hood exhaust fan increases to 100% speed until the smoke/vapor is removed. Energy savings are also realized when the kitchen equipment is operating at less than full load due to minimal cooking operations. During these times the fan speed decreases, removing only the necessary amount of air, saving exhaust fan energy and make up air conditioning energy. Energy Calculations Summary: Detailed calculations for the proposed kitchen hood control system can be found in the Kitchen Exhaust Calculations Appendix. It is pertinent to note that the calculation assumes the exhaust fans and make-up air unit remain off for approximately 17 hours per day. Installed cost of the kitchen hood control system is $23,500. The calculated energy savings equals approximately $2,452 per year. Currently, there aren’t any incentives from the Smart Start program for motors smaller than 5 HP.

ECM #13: Kitchen Domestic Gas Booster Heater
Description: Tankless style hot water heaters provide improved efficiencies compared to standard hot water heaters. In addition, heating with natural gas is far less expensive than domestic hot water heated with electric heat. The existing commercial dishwasher at Ridge High School utilizes an electric booster heater to provide approximately 180°F hot water for sterilization. Installation and capacity could not be verified in the field. Installation is based on similar style system to the middle school. A tankless hot water heater would allow the utilization of a high efficiency natural gas source of hot water boosting production with minimal space requirements. This ECM includes replacement of the existing domestic water booster heater for the commercial kitchen dishwasher. The kitchen booster heater would be replaced with a Takagi commercial hot water heater model number TATM32 with remote temperature controller. This ECM is based on installation of the hot water heater within the boiler room and piping hot water to the commercial kitchen dishwasher. Energy Savings Calculations:

V. ADDITIONAL RECOMMENDATIONS The following recommendations include no cost/low cost measures, Operation & Maintenance (O&M) items, and water conservation measures with attractive paybacks. These measures are not eligible for the Smart Start Buildings incentives from the office of Clean Energy but save energy none the less.
A. Chemically clean the condenser and evaporator coils periodically to optimize efficiency. Poorly maintained heat transfer surfaces can reduce efficiency 5-10%.
B. Maintain all weather stripping on windows and doors.
C. Clean all light fixtures to maximize light output to avoid use of task lighting.
D. Provide more frequent air filter changes to decrease overall system power usage and maintain better IAQ.
E. Turn off computers when not in use. Ensure computers are not running in screen saver mode which saves the monitor screen not energy.
F. Ensure outside air dampers are functioning properly and only open during occupied mode.
It was noted at the site survey that the HVAC systems in several rooms were not controlling temperature correctly. The result of the controls issues causes space temperatures to become uncomfortable and drastic measures such as opening windows on extremely cold days. This type of issue requires a whole system controls evaluation for the building to determine where control problems are taking place. Based on information provided by the operations personnel, there are several control systems within the building which operate different section or systems throughout the building. In addition, multiple control vendors are utilized to maintain the control systems. The use of multiple control systems and control vendors to support the systems will very likely cause issues with the overall function of the building. The systems and controls throughout the district represent a large potential “energy leak” throughout the building. It is recommended to quantify the control system points and verify their proper operation through Retro-Commissioning. Retro-Commissioning allows facility owners to re-establish the operation of the HVAC systems back to the original specifications. A third party evaluation is highly recommended to review the controls of the systems and provide insight into the corrections needed. It is also recommended to consider the renovation of all control systems into one central control system to avoid the overlap and communication gap when utilizing multiple control systems. This renovation should be consistent across all facility throughout Bernards Public Schools to maximize the benefit of central controls.

II. FACILITY DESCRIPTION
The 162,713 SF William Annin Middle School is a two story facility comprised of classrooms, library, computer room, media center, cafeteria, kitchen, two gymnasiums, auditorium, administration offices, restrooms, boiler room, custodial spaces and storage spaces. The School was built in 1968 with additions added in 1999 and 2004. The additions to the building include enlarging the 300 / 400 wing with 20 new classrooms, a new Media Center & small cafeteria for staff, and a new gymnasium addition that also included additional classrooms in the 100 wing and 200 wing.
Building Profile
The hours of operation for the school students and teachers are between 8:30 AM and 3:30 PM on the weekdays. The facility remains occupied between 3:30 PM and 6:00 PM for after school programs during the weekdays. Custodial services are performed between the hours of 6:00 PM and 11:00 PM. The facility is closed on weekends. The student enrollment at the middle school is approximately 1327 students and 166 teachers.
Building Envelope
The facility exterior construction is primarily CMU block with 4-inch brick façade. Portions of the original building classroom wings utilized curtain wall systems with glass windows and insulated metal panels. Insulation within the original building is estimated to consist of an air space between the block wall and brick façade. The construction in the new additions is estimated to have 1”-2” of rigid insulation within the exterior wall. The roof on the building is a flat built up style roof with tar coating and crushed stone on top. The new additions including a newer style built up flat roof with rigid insulation (estimated 2” minimum) and a black rubber roof membrane. The windows throughout the facility are single pane aluminum framed windows in the original building and double pane aluminum frame windows in the building additions. The older windows appear to be in fair to good condition. The windows in the newer sections are in good condition and appear to be providing a tight weather barrier. Blinds for the windows integral to the double pane window system and appear to be in good working order.
HVAC Systems
Heating is provided by a central hot water heating system. The facility utilizes two cast iron sectional style boilers. Each of the Weil McLain 94 Series boilers has an input capacity of 8,371 MBH. These boilers provide heating hot water to baseboards, unit ventilators, and heating and ventilation units throughout the school. The boilers are in good condition and appear to be maintained. During the survey it was noted that both boilers were operating simultaneously to provide heat. The two boilers were cycling to maintain set point for the building.
Three large hot water pumps circulate boiler water throughout the building for two major building zones. One zone serves the 300 & 400 classroom wing, and the other zone serves the rest of the building. All pumps are connected to a header in order for the third pump to serve as a back-up pump for either zone. All three pumps are 10 HP each. Both zones run continuously in the heating season. The pumps are in fair to good condition. One pump motor has been replaced.

Concord Engineering Group, Inc. 9C10088 April 15, 2011– FINAL Page 8 of 55
Terminal heating equipment consists of unit ventilators made by Nesbitt in combination with hydronic baseboard heat. These units serve the classrooms throughout the school and the cafeteria. The unit ventilators appear to be original and in poor condition. The unit ventilators are controlled by the building pneumatic system. In many cases these controls are not functioning correctly due to leaks in the system or failure of the control valves resulting in lack of temperature control. As a result of these issues, the poorly controlled classrooms as well as other spaces have windows open in the winter to maintain comfortable temperatures.
The newer classrooms in the building addition utilize vertical style packaged heating and cooling units made by Airedale. Each classroom has a dedicated unit with overhead ductwork for air distribution. Heat is provided by hot water heating coils fed from the central boiler plant. Cooling is packaged within the unit and heat is rejected through an exterior wall louver. Each unit is installed within an enclosed cabinet in the corner of the classroom. These units can be removed from the cabinet for service. The packaged Airedale units are loud and seem to be in fair / poor condition despite their recent installation within the building additions.
The building also utilizes large heating and ventilation units with hot water coils that provide heat for the large open areas such as the gymnasium and auditorium. These units appear to be original to the building and in poor condition. The H&V units within the auditorium have been retrofitted to include electronic controls with electronic actuators and control valves. The auditorium H&V units are also retrofitted with variable frequency drives on the supply air fan motors. It is unknown what control scheme is utilized to control the variable frequency drive speed. At the time of the survey, the VFDs were running at 30 Hz (1/2 speed) when the auditorium was unoccupied.
In addition to the hot water system, several spaces utilized packaged roo0ftop heating and cooling units for heat with gas fired heat exchangers or hot water heating coils. The packaged units provide heat for various classrooms and spaces such as the library, computer room, media center, and small cafeteria.
Cooling is provided for several spaces within the school. All of the new addition classrooms have air conditioning units provided by the package Airedale units. Packaged rooftop units with air conditioning provide cooling for various classrooms, the library, media center, computer room, and small cafeteria. These units are made by Lennox and are in fair to good condition. The remaining cooling throughout the building is provided by split systems and a few spaces utilize window air conditioners. The split system AC units provide cooling for other classrooms throughout the building as well as office areas. These units include ductless split systems made by Sanyo and Mitsubishi Electric as well as standard split systems made by Trane. These unit vary in age and condition.
Exhaust System
Exhaust is provided by roof top mounted exhaust fans primarily located over the hallways. The exhaust fans are utilized to relieve the excess building pressure due to outside air brought in through the unit ventilators and packaged rooftop units. It is unknown if these units operate based on a time schedule and shut down in occupied mode. Bathrooms and toilet rooms are
Bernards Public Schools – William Annin Middle School Energy Audit
Concord Engineering Group, Inc. 9C10088 April 15, 2011– FINAL Page 9 of 55
exhausted through smaller rooftop exhaust fans typically interlocked with the bathroom wall switch.
The kitchen includes a 4FT x 20FT commercial exhaust hood, which provides exhaust for cooking equipment. The kitchen hood is manually controlled with a wall switch. The exhaust fan is running based on the needs from the kitchen staff. It is estimated that the exhaust fan runs 6 hrs per day.
HVAC System Controls
The building HVAC system is a combination of an old pneumatic system that controls the older unit ventilators and H&V units, and newer electronic controls that control the equipment in the building additions. The pneumatic control system is in poor condition and in many spaces, significantly lacks in proper temperature control. The terminal units throughout the building hot water system is controlled by a combination of two way control valves and three way control valves. Unit ventilators appear to all utilize two way control valves and the larger H&V units as well as make up air rooftop unit utilize 3-way control valves. In this scheme, the hot water pumps are not controlled and run at constant speed. Excess water flow in low load conditions is bypassed throughout the building 3-way control valves in lieu of slowing the pumps down.
Domestic Hot Water
Domestic hot water is provided to the school by one domestic hot water heater. The school utilizes a 98 gallon natural gas hot water heater made by Bradford White in good condition. The main building HWH is located in the main boiler room and appears to have been recently replaced. Domestic hot water is circulated to the bathrooms and sinks by a small re-circ pump controlled by an aqua stat.
The kitchen utilizes a domestic hot water booster pump that increases the water temperature to approximately 180°F for the kitchen dishwasher. The hot water booster heater is an instantaneous style electric booster heater with a capacity of 36 KW. The dishwasher runtime is estimated to be 2-3 hrs per day.
Lighting Typical lighting throughout school building is fluorescent tube lay-in fixtures with T-12 lamps and magnetic ballasts. Some of the storage rooms and closets including the boiler room is lit with a mixture of incandescent lamps and compact fluorescent lamps. The gym is lit with 400W metal halide fixtures. The building exterior is lit with 175W metal halide flood lights.

ECM #1: Lighting Upgrade – Interior spaces Description: The majority of the interior lighting throughout William Annin Middle School is provided with fluorescent fixtures with older generation, 700 series 32W T8 lamps and electronic ballasts. Although 700 series T8 lamps are considered fairly efficient, further energy savings can be achieved by replacing the existing T8 lamps with new generation, 800 series 28W T8 lamps without compromising light output. CEG recommends, re-lamping all of the fixtures with 28W T8 lamps. In addition, some of the storage areas, locker room and gym areas, offices, auditorium, classrooms, restrooms and kitchen areas still have a variety of older fluorescent fixtures with magnetic ballasts and incandescent lamps. It is recommended to retrofit or replace all of the older fluorescent fixtures and the incandescent lights in these areas with high efficiency fluorescent T8 or T5 fixtures with electronic ballasts or compact fluorescent lamps. This ECM includes re-lamping of the existing fluorescent fixtures with 800 series, 28W T8 lamps. The ECM also includes retrofit of all older fluorescent fixtures with T8 or T5 fluorescent fixtures with electronic ballasts in the building. The new, energy efficient T8 fixtures will provide adequate lighting and will save on electrical costs due to better performance of the lamp and ballasts. Energy Savings Calculations: The Investment Grade Lighting Audit Appendix outlines the hours of operation, proposed retrofits, costs, savings, and payback periods for each set of fixtures in the each building. Rebates and Incentives: There are no incentives available from NJ Smart Start® Program for the retrofits in this ECM. Replacement and Maintenance Savings: There is no significant replacement and maintenance savings due to implementation of this ECM.

ECM #2: Lighting Controls Upgrade – Occupancy & Daylight Sensors Description: Some of the lights in the school building are left on unnecessarily. In many cases the lights are left on because of the inconvenience to manually switch lights off when a room is left or on when a room is first occupied. This is common in rooms that are occupied for only short periods and only a few times per day. In some instances lights are left on due to the misconception that it is better to keep the lights on rather than to continuously switch lights on and off. Although increased switching reduces lamp life, the energy savings outweigh the lamp replacement costs. The payback timeframe for when to turn the lights off is approximately two minutes. If the lights are expected to be off for at least a two minute interval, then it pays to shut them off.
Lighting controls come in many forms. Sometimes an additional switch is adequate to provide reduced lighting levels when full light output is not needed. Occupancy sensors detect motion and will switch the lights on when the room is occupied. Occupancy sensors can either be mounted in place of a current wall switch, or on the ceiling to cover large areas. The U.S. Department of Energy sponsored a study to analyze energy savings achieved through various types of building system controls. The referenced savings is based on the “Advanced Sensors and Controls for Building Applications: Market Assessment and Potential R&D Pathways,” document posted for public use April 2005. The study has found that commercial buildings have the potential to achieve significant energy savings through the use of building controls. The average energy savings are as follows based on the report:
• Occupancy Sensors for Lighting Control 20% - 28% energy savings.
Savings resulting from the implementation of this ECM for energy management controls are estimated to be 20% of the total light energy controlled by occupancy sensors. Daylight sensor savings is estimated to be 40%. (The majority of the occupancy sensor savings is expected to be after school hours when rooms are left with lights on) This ECM includes installation of ceiling or switch mount sensors for individual offices, classrooms, large bathrooms, and libraries. Sensors shall be manufactured by Sensorswitch, Watt Stopper or equivalent. The Investment Grade Lighting Audit Appendix of this report includes the summary of lighting controls implemented in this ECM and outlines the proposed controls, costs, savings, and payback periods. The calculations adjust the lighting power usage by the applicable percent savings for each area that includes lighting controls. Energy Savings Calculations:

ECM #3: Computer Monitor Replacement Description: The computers throughout the facility utilize a mixture of CRT computer monitors and LCD computer monitors. The CRT computer monitors within the offices and classrooms are outdated and have several disadvantages such as; significantly increased energy consumption, uses large amount of desk space, poor picture quality, distortions and flickering image, secular glare problems, high weight, and electromagnetic emissions. Many of these drawbacks are difficult to quantify except for the energy use. CRT monitors use considerably more energy than an alternative flat panel LCD monitor. Replacement of the existing CRT monitors with LCD monitors saves considerable energy as well as provides other ergonomic benefits. Based on the site survey it was noted that there are 121 LCD monitor and 201 CRT monitors. Some of the monitors were left in screen saver mode, which only saves the computer screen from image burn in, however it does not save on energy consumption. The average operating hours for all computers and monitors is estimated based on the site survey observations. Energy consumption of computer monitors is based on averages for power usage of various computer monitors. This ECM includes replacement of all existing CRT monitors with LCD flat panel monitors throughout the facility. Installation costs were neglected for this ECM with the intention that this ECM would be replaced by the school district. The calculations are based on the following operating assumptions: Energy Savings Calculations: No. of CRT Monitors: 201 Operating Weeks per Yr: 42 Hrs per Week: 60 (12 hrs per day estimated average)

ECM #4: Air Conditioning Unit Upgrades
Description:
William Annin is air conditioned by split system AC units and packaged rooftop units. The rooftop AC units vary in age from units close to the end of their rated life to new and in good condition. The split system AC units also have a wide range of condition and age. The rooftop units were analyzed for their efficiency and overall condition. The majority of the rooftop units with the exception of the new wings utilize packaged AC systems made by Lennox. These units were found to be the high efficiency model when purchased approximately 13 years ago. Although newer more efficient units are available, there is a minimal efficiency increase from the existing equipment to new units.
The split system AC units currently installed are vary in efficiency levels. Some units are high efficiency models where other split systems are old and inefficient compared to modern equipment. The older units and can be replaced with new high efficiency units. New air conditioners provide higher full load and part load efficiencies due to advances in inverter motor technologies, heat exchangers and refrigerants. This ECM includes one-for-one replacement of the older split system air conditioning units with new higher efficiency systems. It is recommended to fully evaluate the capacity needed for all new systems prior to moving forward with this ECM. A summary of the unit replacements for this ECM can be found in the table below:
The manufacturers used as the basis for design are Trane, Carrier, and Fujitsu. This ECM includes replacement of the outdoor condensing units and associated indoor air handling units or cooling coils where appropriate. No rooftop units are included in this ECM. All units are one for one style replacements with matching capacity of the new units to the old units.

ECM #5: Install New Unit Ventilators Description: The heating and air conditioning for the new additions at William Annin Middle School is provided by upright style Airedale unit ventilators. These unit ventilators are approximately 13 years old and near the end of expected useful service life, which is fifteen (15) years per ASHRAE. There are approximately 25 unit ventilators in the original section of the facility. The units are packaged with 4-ton (21 units) and 6-ton (4 units) cooling capacities and hot water heating coils. Currently, the units are monitored and controlled by the building management system. It is recommended to replace older unit ventilators with modern unit ventilators with built-in energy recovery wheels. The advantage of this setup is the utilization of the energy recovery system to recover the energy in the exhaust air in order to reduce the heating and cooling demand of the classrooms. This ECM replaces 25 existing older unit ventilators with new unit ventilators with high efficiency R410A compressors, hot water heating coils and built-in energy recovery wheels. The basis for this ECM is Airedale Classmate CHX-4&5 model unit ventilator with 450 CFM Energy Recovery ventilators and higher EER cooling modules. Energy Savings Calculations: The energy savings calculations are based improved full load cooling efficiency of the unit ventilators and the energy recovery capacity of the recovery wheels. There will be no heating energy savings due to the upgrade since both existing units and new units utilize hot water coils. Cooling energy consumption, electric demand and operation cost of each unit are calculated using the formulas below:

ECM #6: Valve Blanket and Pipe Insulation
Description: The boiler plant supplies heating hot water to the facility for heating season. The piping remains heated at approximately 180°F continuously during this period (approximately 6 months). Un-insulated piping has significant heat losses due to the exposure of the steel piping to the surrounding air. Insulated piping has a heat loss which is a small fraction of the heat loss from un-insulated piping. It was noted that significant piping within the boiler room was missing piping insulation including numerous valves throughout the system. Based on the site survey approximately 24 large diameter pipe valves and 40 feet of 8” steel pipe was not insulated. Valve blankets are designed to provide insulation value over large hydronic valves that must remain accessible. This ECM includes installation of valve blankets on all exposed boiler system valves and insulation of all un-insulated piping within the boiler room.

ECM #7: Install Pump VFD’s Description: The packaged rooftop air conditioners, heating and ventilation units and the unit ventilators are utilizing a constant volume pumping design. The unit ventilators are equipped with 2-way control valves and the rooftop units have 3-way control valves which allow continuous flow through the piping loop throughout the building. As a result the water loop pumps must provide nearly full power output to circulate the water through all rooftop units and unit ventilators continuously. 2-way control valves provide flow through the heat exchanger equipment only when there is a call for heating or cooling, unlike 3-way control valves that allow constant flow of the water loop. 3-way control valves require full pumping energy continuously, while 2-way control valves allow the system to reduce flow when it is not needed. This measure includes capping off the bypass port on the 3-way control valves which effectively turns the valves into “2-way” control valves. When the unit is not calling for heating, the control valve closes reducing overall flow of the system. Variable frequency drives allow the pumps to slow down in response to a reduction in overall system flow. The reduction in operating flow allows the pumps to reduce energy consumption for all hours that the heating system is not at its peak load. This ECM includes the installation of Variable Frequency Drives on the three (3) existing 10 horsepower hot water pumps in conjunction with piping modifications at the rooftop units and H&V units to cap off the bypass port on the 3-way control valves. The VFD’s would be controlled by a differential pressure sensor in the water loop to measure demand for water. The furthest unit from the loop pumps would remain as 3-way control valves (constant flow) to eliminate dead heading potential. This ECM also includes replacement of the existing pump motors with inverter duty motors that meet NEMA Premium Efficiency Standard, which also helps to reduce energy consumption. Energy and cost savings calculations are based on calculation software “PumpSave v4.2,” provided by ABB. The PumpSave calculation software is used to estimate the pumping energy for variable speed pump systems. Two of the boiler water loop pumps operate approximately 4,380 Hrs per year since this system is used for about 6 month’s total. The pump flow, HD, and resultant energy are calculated based on the existing pump horse power installed. Calculation is based on all existing unit ventilators to remain with 2-way control valves. This should be verified before implementing this ECM. Energy Savings Calculations:

ECM #8: Kitchen Domestic Gas Booster Heater
Description: Tankless style hot water heaters provide improved efficiencies compared to standard hot water heaters. In addition, heating with natural gas is far less expensive than domestic hot water heated with electric heat. The existing commercial dishwasher at William Annin utilizes an electric booster heater to provide approximately 180°F hot water for sterilization. A tankless hot water heater would allow the utilization of a high efficiency natural gas source of hot water boosting production with minimal space requirements. This ECM includes replacement of the existing domestic water booster heater for the commercial kitchen dishwasher. The kitchen booster heater would be replaced with a Takagi commercial hot water heater model number TATM32 with remote temperature controller. This ECM is based on installation of the hot water heater within the boiler room and piping hot water to the commercial kitchen dishwasher. Energy Savings Calculations:

ECM #9: Demand Controlled Ventilation Demand Controlled Ventilation (DCV) is a means to provide active, zone level control of ventilation for spaces within a facility. The basic premise behind DCV is monitoring indoor CO2 levels versus outdoor CO2 levels in order to provide proper ventilation to the spaces within the facility as well as saving costly dollars treating unconditioned ventilation air. Carbon dioxide ventilation control or demand controlled ventilation (DCV) allows for the measurement and control of outside air ventilation levels to a target cfm/person ventilation rate in the space (i.e., 15 cfm/person) based on the number of people in the space. It is a direct measure of ventilation effectiveness and is a method whereby buildings can regain active and automatic zone level ventilation control, without having to open windows. The fixed ventilation approach depends on a set-it-and-forget-it methodology that is completely unresponsive to changes in the way spaces are utilized/occupied or how equipment is maintained. A DCV system utilizes various control algorithms to maintain a base ventilation rate. The system monitors space CO2 levels and the algorithm automatically adjusts the outdoor and return air dampers to provide the quantity of outdoor air to maintain the required CO2 level in the space. System designs are normally designed for maximum occupancy and the ventilation rates are designed for this (maximum) occupancy. In areas where occupancy swings are prevalent there is ample opportunity to reduce outdoor air quantity to satisfy the needs of the actual number of occupants present. By installing the DCV controls, energy savings are realized by the reduced quantities of outdoor air that do not require heating energy from the boiler plant. There are large heating and ventilation units (H&V) providing heating and air conditioning to the gymnasium. When operating, these units provide minimum amount of outside air to the space. The outside air volume is typically based on the maximum occupancy of the space conditioned. When a given space is not fully occupied the outside air quantity delivered to the space is greater than the amount needed for adequate ventilation. This ECM includes the installation of CO2 sensors integrated into a demand control ventilation system, for the units mentioned above. The components required for the demand control ventilation system installation include damper actuators, CO2 sensors, wiring, controls equipment and programming. The gymnasium would require one CO2 sensor installed per unit to monitor occupancy levels. Often heating and air conditioning units switch to occupied mode several hours before the actual occupancy in order to provide pre-heating or pre-cooling of the space. Energy savings achieved through “Demand Control Ventilation” is calculated based on actual occupancy of the spaces and the hours the units are in occupied mode.

ECM #10: Condensing Boiler Installation Description: Space heating for the perimeter offices and classrooms in the majority of the school is provided with unit ventilators and cabinet heaters with hot water coils and hot water radiators. The source of hot water for this equipment is two (2) hot water boilers located in the main boiler room. The input capacity of the boilers is 8.371 MMBH (106 BTU/H) each. The boilers appear to be close to their rated life; however, this is not necessarily a good indicator of the end of useful life particularly when boilers are well maintained. This ECM provides insight into the energy efficiency benefit of condensing boiler technology compared to standard cast iron boilers. Standard (non-condensing) boilers provide lower than nominal efficiency compared to condensing boilers. Standard boilers suffer further efficiency losses at part load operating conditions mainly due to limitations in the reduction of the flue gas temperature. Current average combustion efficiency of each boiler is estimated to be 75% due to standard non-condensing boiler technology, limited turn down ratio, cycling losses and outdated design and controls. A new condensing boiler could substantially improve the operating efficiency of the heating system of the building. Condensing boiler’s peak efficiency tops out at 99% depending on return water temperature. This ECM is based on the replacement of the two (2) boilers with condensing hot water boilers to provide the building with heating throughout the year. The annual average operating efficiency of the proposed boiler set is expected to be 90%, which gives the heating system a 15% increase in efficiency. This ECM is based on variable supply water temperature adjusted based on outdoor temperature. This ECM includes installation of four (4) new condensing gas fired boilers to replace two (2) existing hot water boilers. The basis for this ECM is Aerco Benchmark 2.0 condensing hot water boilers or equivalent. New boilers shall be setup and programmed to be the primary source of heating for the building during the entire year. The owner is recommended to retain a professional engineer to confirm equipment sizing and finalize design.
Energy Savings Calculations: Currently there are multiple boilers and gas fired rooftop units on the building gas meter. The boilers’ gas usage is not separately metered. Therefore, annual energy consumption of the boilers has to be estimated. This calculation is based on the energy consumption of the boilers in proportion with the ratio of the total heating capacity of each gas fired piece of equipment. First, domestic hot water usage is estimated and subtracted from the total usage in order to estimate the net natural gas usage for space heating. Current total hot water usage can be found in the table below:

ECM #11: Install NEMA Premium® Efficiency Motors Description: The improved efficiency of the NEMA Premium® efficient motors is primarily due to better designs with use of better materials to reduce losses. Surprisingly, the electricity used to power a motor represents 95 % of its total lifetime operating cost. Because many motors operate continuously 24 hours a day, even small increases in efficiency can yield substantial energy and dollar savings. The electric motors driving the hot water pumps in the old boiler room and supply fans in some of the rooftop equipment are candidates for replacing with premium efficiency motors. These standard efficiency motors run considerable amount of time over a year. This energy conservation measure replaces existing electric motors over 5 HP or more with NEMA Premium® efficiency motors. NEMA Premium® is the most efficient motor designation in the marketplace today.

ECM #12: Window Replacement Description: Some areas of William Annin Middle School façade includes older windows with single pane glass and inefficient frames. Older single pane windows can account for significant energy use through leakage heat loss and conductive heat loss. The age and condition of the windows contribute to the leakage rate of the building. The single pane construction allows higher thermal (conductive) energy loss. These factors lead to increased energy use in the heating and cooling season. The heating loss due to single pane glass is combined with heat loss due to poor seals at each operable window / door. New double pane windows with low E glazing offer a substantial improvement in thermal performance in the winter and summer months. This ECM includes the replacement of the older single pane windows within the connecting hallways between the 200 wing and the two story 300/400 wing. This ECM is based on new double pane windows with low emissivity glass. The proposed windows include reduced outside air leakage. In addition the double pane structure will significantly increase the insulation value compared to the existing single pane window structure. The basis for this ECM is Anderson Windows at an estimated installation cost of $75 per SF of window installed. The proposed installation is for the older portion of the building with the existing curtain wall system. Below is a list of areas with older and inefficient windows:

ECM #13: Lighting Upgrade – Gymnasium & Auditorium Description: The two gymnasiums at William Annin Middle School utilize 400W metal halide fixtures for its lighting. Metal halide bulbs provide a reasonably efficient option for bay lighting however a few draw-backs that are common. Metal halide fixtures often have poor overall efficacy which limits the amount of light actually leaving the fixture. Also metal halide bulbs require a significant warm-up period and even longer cool down period eliminating the potential for occupancy sensors frequent switching. This symptom encourages the gymnasium lighting to be left on continuously during the day. Another drawback is the reduced lumen output (Lumen Maintenance) of the metal halide bulb over its life time. Average bulb output or “mean lumens,” is approximately 25% less than the bulb’s initial lumens for typical metal halide lamps. In addition the most rapid rate of light output decline is during the beginning of its life, approximately 15-20% light loss within the first 20% of its rated life. It is important to note that the light loss has no savings in energy used; therefore the overall light efficiency is continuously decreasing with age. The final drawback is the light quality or Color Rendering Index (CRI). Typical values for metal halide bulbs is 65, which is a measure of how close the light is to true “full spectrum” light produced by sunlight or incandescent lighting. Metal halide bulbs also show noticeable color shifting when the bulb is reaching the end of its life. Utilizing fluorescent fixtures in low and high bay spaces is a superior option over metal halide fixtures in all areas described above. Although metal halide fixtures provide light very efficiently at the start of the bulb life, the average efficiency over the life is below that of fluorescent fixtures. The Middle School also utilizes dimmable incandescent fixtures within the Auditorium. These fixtures are the primary source of light for the auditorium. Incandescent fixtures are extremely inefficient compared to other sources of light; however these fixtures can be dimmed easily. LED fixtures provide a comparable replacement for fixtures that require dimming. LED fixtures require substantially less energy than incandescent. In addition the operating hours for LED fixtures are approximately 50 time greater than incandescent bulbs. This ECM includes replacement of each of the existing gymnasium high bay metal halide light fixtures with T5HO fixtures with reflective lenses. The retrofit for the metal halide fixtures includes a one for one fixture replacement. The fluorescent fixtures selected will provide equivalent light compared to the average light output of the existing metal halide fixtures. The bulb replacement cost for T-5 HO lamps compared to the existing metal halide lamps were found to be approximately equal and therefore not included in the savings calculations. This ECM also includes replacement of the incandescent fixtures within the auditorium with recessed dimmable LED fixtures. The intent of this ECM is to utilize the existing dimming controls to operate the new LED fixtures. The compatibility of the existing lighting controls with the new LED fixtures should be verified before implementation of this ECM. Hours of Operation

V. ADDITIONAL RECOMMENDATIONS The following recommendations include no cost/low cost measures, Operation & Maintenance (O&M) items, and water conservation measures with attractive paybacks. These measures are not eligible for the Smart Start Buildings incentives from the office of Clean Energy but save energy none the less.
A. Chemically clean the condenser and evaporator coils periodically to optimize efficiency. Poorly maintained heat transfer surfaces can reduce efficiency 5-10%.
B. Maintain all weather stripping on windows and doors.
C. Clean all light fixtures to maximize light output to avoid use of task lighting.
D. Provide more frequent air filter changes to decrease overall system power usage and maintain better IAQ.
E. Turn off computers when not in use. Ensure computers are not running in screen saver mode which saves the monitor screen not energy.
F. Ensure outside air dampers are functioning properly and only open during occupied mode.
It was noted at the site survey that the HVAC systems in several rooms were not controlling temperature correctly. The result of the controls issues causes space temperatures to become uncomfortable and drastic measures such as opening windows on extremely cold days. This type of issue requires a whole system controls evaluation for the building to determine where control problems are taking place. Based on information provided by the operations personnel, there are several control systems within the building which operate different section or systems throughout the building. In addition, multiple control vendors are utilized to maintain the control systems. The use of multiple control systems and control vendors to support the systems will very likely cause issues with the overall function of the building. The systems and controls throughout the district represent a large potential “energy leak” throughout the building. It is recommended to quantify the control system points and verify their proper operation through Retro-Commissioning. Retro-Commissioning allows facility owners to re-establish the operation of the HVAC systems back to the original specifications. A third party evaluation is highly recommended to review the controls of the systems and provide insight into the corrections needed. It is also recommended to consider the renovation of all control systems into one central control system to avoid the overlap and communication gap when utilizing multiple control systems. This renovation should be consistent across all facility throughout Bernards Public Schools to maximize the benefit of central controls.
