REPORT DISCLAIMER
This audit was conducted in accordance with the standards developed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) for a Level II audit. Cost and savings calculations for a given measure were estimated to within ±20%, and are based on data obtained from the owner, data obtained during site observations, professional experience, historical data, and standard engineering practice. Cost data does not include soft costs such as engineering fees, legal fees, project management fees, financing, etc. A thorough walkthrough of the school was performed, which included gathering nameplate information and operating parameters for all accessible equipment and lighting systems. Unless otherwise stated, model, efficiency, and capacity information included in this report were collected directly from equipment nameplates and /or from documentation provided by the owner during the site visit. Typical operation and scheduling information was obtained from interviewing staff and spot measurements taken in the field.

The windows in classrooms and offices are operable aluminum frame single glazing windows. Hallway windows are non-operable aluminum frame, single glazing. The windows seem to be in fair condition, however, the seals along the window perimeters are in poor condition allowing outdoor air to infiltrate into the building. The seals around exterior windows fail over time. This leads to unwanted infiltration of unconditioned outside air and exfiltration of conditioned air resulting in increased heating energy usage. This measure calls for the replacement of all exterior window seals. Replacement of these seals will result in a reduction of the building’s heating load, therefore providing natural gas savings. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

This measure is not recommended due to the long payback period and negative ROI.
4.1.2 ECM-2 Replace Door Seals & Sweeps During the site visit it was observed that seals and sweeps on doors have deteriorated and are no longer useful in preventing outdoor air infiltration. Gaps between the doors and frames were noticeable and allowed for outdoor air to infiltrate the building. The calculation uses bin weather data to estimate the occupied and unoccupied bin hours. This is converted to existing energy for the occupied and unoccupied cases using the existing estimated infiltration rate and the heating temperature. The two are summed together to create the annual utility usage for the baseline. The same steps are done to calculate the proposed utility usage. The difference in heating losses through the doors results in annual heating natural gas savings. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

4.2 HVAC Systems 4.2.a Heating Systems The school has (2) hot water boilers. An older Weil-McLain Series 1094-3 boiler rated at 2,028 MBH output and 77% efficiency operates as the lead boiler. The lag boiler is a Smith Series 28A-12 boiler rated at 2,232 MBH output and 78% efficiency. The Smith boiler was installed in 2005. Two 78.5% efficient 1.5 HP primary pumps circulate the HW through the boilers. Two 80% efficient 3 HP pumps operating in lead/lag circulate the heating HW throughout the building to provide heating to various rooms and hallways. Heating in classrooms are provided by heating only unit ventilators which are controlled by pneumatic thermostats. Hallways are heated by ceiling mounted fan coil units with thermostats located in the hallways throughout the school. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B. 4.2.b Cooling Systems The majority of the original school does not have any air conditioning systems in place. There is (1) DX split system dedicated to the guidance office with a condensing unit on the roof that provides cooling to that area. The unit has a rated cooling capacity of 9,000 btu/h and an energy efficiency ratio (EER) of 10.5. There were also a number of window air conditioning units utilized in classrooms and the main office which ranged in age. These units are controlled by the teachers in those classrooms. Some of the units were quite old and could be upgraded to energy star units. It was noted during the field survey that the window units may change location in order to accommodate students with allergies. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B.
New Jersey BPU – Parsippany-Troy Hills Board of Education- Energy Audit 9 | P a g e
4.2.c Ventilation Systems Every classroom in Troy Hills Elementary School has a unit ventilator. Unit ventilators (UV) provide heating and ventilation to the classroom using hot water coils fed from the boilers. A small fan moves the air through the coil to provide heating. Modulating dampers control the amount of indoor recirculated air and outdoor air flow. The units are typically attached to an exterior wall which allows the unit to get ventilation air directly from the outdoors without using ducting. The UV’s are controlled by pneumatic thermostats that regulate the heating to the user set point. There is one ceiling hung heating & ventilation (HV) unit located in the multipurpose room. This unit was controlled by a thermostat on the wall inside the multipurpose room. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B. 4.2.d Exhaust Systems As ventilation units bring outdoor air into the building, exhaust systems move indoor air into the atmosphere. During the site visit it was recorded that approximately (9) exhaust fans were located on the roof to remove air from classrooms, hallways, bathrooms, and the multipurpose room. The exhaust fans were found to be in good condition. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B. The following ECMs were identified as HVAC system improvements: 4.2.1 ECM-3 Install Condensing Hot Water Boilers There is a Weil-McLain Boiler operating at efficiency of 77% and a Smith Boiler operating at an efficiency of 78% serving the school. Both boilers are non-condensing hot water boilers. A heating system with a 92% efficiency was proposed as a replacement. The boiler fuel consumption was calculated from the estimated system efficiency and the natural gas consumed annually per the utility bills. This was then compared to the improved efficiency of a new condensing boiler and hot water distribution system. The difference in fuel usage was the savings. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

This measure is not recommended due to the high capital cost and therefore long payback period. Note: there may be insufficient ventilation levels within the building per current code requirements, but ventilation levels were not evaluated as part of the measure. If ventilation must be increased to meet codes the boiler fuel consumption may increase. 4.2.2 ECM-4 Install Premium Efficiency Pump Motors The existing heating system pumps do not have premium efficiency motors. This ECM evaluated replacing the existing standard efficiency pump motors with premium efficiency units. Savings were determined by comparing the energy usage of the existing fan motors to the energy usage with premium efficiency motors. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

condition of some units ranges from fair to poor. Replacement of the existing window units with newer energy star appliances was assessed. It is assumed that the maintenance staff will install the units. It was noted during the field survey that some window mounted AC units change location between school years in order to accommodate students with allergies. The assumption of this calculation is that the operating hours and capacity stay the same. The energy savings result from operating a higher efficiency unit. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

This measure is not recommended due to the low energy sayings and long payback period. However the additional maintenance costs associated with constantly moving the window a/c units year to year might justify the installation of more portable air conditioning units such as Move N’ Cool. 4.3 Control Systems The hydronic heating system includes classroom unit ventilators, HV units cabinet heaters. The boilers utilize electronic controls tied into a boiler management system (BMS), however the rest of the building is still maintained by pneumatics. The BMS allows the temperature of the hot water to be reset based on the outdoor air temperature. The pneumatic system includes valves; actuators and dampers controlled by (2) split HP air compressor motors. Thermostats are located in classrooms, hallways and the multipurpose room. The typical setpoint for the pneumatic sections is 72oF heating, with a setback temperature of 65oF. The HW pumps and HV unit in the multipurpose room are controlled by Hand-Off-Auto (HOA) switched. There are no ECMs associated with the controls systems.

4.4 Domestic Hot Water System Domestic hot water (DHW) is heated by (1) 98% efficient Bradford-White 80 gallon electric water heater rated at 4.5 kW. The DHW system is maintained at 120F and serves toilet rooms and sinks located throughout the school. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B. The following ECMs identify an improvement to the school’s Domestic Hot Water System: 4.4.1 ECM-6 Replace Domestic Hot Water Heater with Instantaneous unit This ECM assesses replacing this domestic water heater with a tankless type natural gas domestic water heater of appropriate size for the building. According to the U.S. Department of Energy, 2.5% of stored capacity is lost every hour during DHW heater standby. This value was applied to the total volume to determine annual standby losses. Proposed efficiency was based on a typical high efficiency natural gas condensing type hot water heater. The new water heater will require water and gas piping modifications, venting, and electrical connections. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

4.5 Kitchen Equipment There is no kitchen at the Troy Hills Elementary School. Food is prepared at either Parsippany High School or Brooklawn Middle School and delivered to Troy Hills each day. The food is then served to students and kept warm in electric powered warming stations. There are no ECMs associated with the controls systems. 4.6 Plumbing Systems Troy Hills Elementary School has older style fixtures in the classroom restrooms. Several of the hallway restrooms have newer, low flow fixtures. The older style plumbing fixtures consume more water than modern plumbing fixtures. There are (13) water closets in the school with an average water usage of 5.5 gallons per flush (GPF), and (11) low flow water closets with an average water usage of 1.6 GPF. There are (10) urinals in the school, with an average of 2.5 GPF and 40 faucets with an average flow rate of 3 gallons per minute (GPM). Each classroom has a sink, while only the kindergarten and first grade classrooms have restrooms. Per the number of occupants, it was estimated that each toilet and faucet is utilized approximately 4 times per day. The following ECM identifies an improvement to the school’s Domestic Hot Water System: 4.6.1 ECM-7 Water Conservation (Low Flow Fixtures) The water savings associated from replacing these fixtures with low-flow fixtures was calculated by taking the difference of the annual water usage for the proposed and base case. The basis of this calculation is the number of times each fixture is used, gallons per use, and number of fixtures. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

4.7 Lighting/Electrical Systems The majority of the lighting in Troy Hills Elementary School is comprised of T-8 fluorescent tube fixtures with electronic ballasts and incandescent lamps. The lighting in the Multi-Purpose room has been recently upgraded to fluorescent T5 fixtures with electronic ballasts. The bathrooms in the kindergarten classrooms have single bulb incandescent fixtures. The building’s exterior lighting includes several high pressure sodium wall pack units. The pole lights in the parking lot and playground are property of Jersey Central Power and Light, and are billed monthly. A comprehensive lighting survey can be found in Appendix B. Troy Hills Elementary School utilizes 153 computers throughout the building in classrooms, offices, media centers and computer labs. All computers have flat screen LCD monitors. The following ECMs identified are improvements to Troy Hills Elementary School’s lighting and electrical system: 4.7.1 ECM-8 Lighting Replacement / Upgrades The school uses mostly T-8 fixtures with electronic ballasts in classrooms, offices, and hallway spaces. Single bulb incandescent fixtures were used in closets, storage rooms, and small bathrooms. Each switch and circuit was identified, and an inventory of fixtures, controls and locations was established during the field survey (Appendix B). There is an opportunity to reduce consumption by upgrading the incandescent fixtures to compact fluorescent lamps. This would involve a replacement of the bulb, The exterior lighting on the building walls is proposed to be changed from high pressure sodium to LED, which has a longer life and consumes much less energy. This will involve a full replacement. Energy savings for this measure were calculated by applying the existing and proposed fixture wattages to estimated times of operation. These calculations are based upon 1 to 1 replacements with the fixtures. They do not take into account lumen output and square footage. A more comprehensive study may be performed to determine correct lighting levels. Supporting calculations, including assumptions for lighting hours and annual energy usage for each fixture, are provided in Appendix C. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

This measure is not recommended in lieu of ECM-10. 4.7.2 ECM-9 Install Lighting Controls (Occupancy Sensors) Currently the light fixtures within classrooms, multipurpose room and the media center are controlled via switches regardless of occupancy. Therefore, installing an occupancy sensor in these spaces to turn off lights when the areas are unoccupied was assessed. This measure recommends installing occupancy sensors for the current lighting system. Using a process similar to that utilized in section 4.7.1, the energy savings for this measure was calculated by applying the known fixture wattages in the space to the estimated existing and proposed times of operation for each fixture. The difference between the two values resulted in an annual savings of 40,500 kWh. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

4.7.3 ECM-10 Lighting Replacements with Controls (Occupancy Sensors) This measure is a combination of ECM-8 and ECM-9; recommending replace/upgrade the current lighting fixtures to more efficient ones and installing occupancy sensors on the new lights. Interactive effects of the higher efficiency lights and occupancy sensors lead the energy and cost savings for this measure to not be cumulative or equivalent to the sum of replacing the lighting fixtures alone and installing occupancy sensors without the lighting upgrade. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

recommended measures identified in a previous energy assessment, such as this energy audit. The incentive is reimbursed to the school upon successful replacement and payment of the equipment. This school is eligible to receive funding from the Direct Install Program because the electrical demand is less than the maximum peak electrical demand of 150 kW in the last 12 month period. Refer to appendix D for more information on this program. 5.1.3 New Jersey Pay For Performance Program (P4P) The facility will be eligible for incentives from the New Jersey Office of Clean Energy. The most significant incentives are available from the New Jersey Pay for Performance (P4P) Program. The P4P program is designed for qualified energy conservation projects applied to facilities whose demand in any of the preceding 12 months exceeds 100 kW. This average minimum has been waived for buildings owned by local governments or municipalities and non-profit organizations, however. Facilities that meet this criterion must also achieve a minimum performance target of 15% energy reduction by using the EPA Portfolio Manager benchmarking tool before and after implementation of the measure(s). If the participant is a municipal electric company customer, and a customer of a regulated gas New Jersey Utility, only gas measures will be eligible under the Program. Available incentives are as follows: Incentive #1: Energy Reduction Plan – This incentive is designed to offset the cost of services associated with the development of the Energy Reduction Plan (ERP).
Incentive Amount: $0.10/SF Minimum incentive: $5,000 Maximum Incentive: $50,000 or 50% of Facility annual energy cost
The standard incentive pays $0.10 per square foot, up to a maximum of $50,000, not to exceed 50% of facility annual energy cost, paid after approval of application. For building audits funded by the New Jersey Board of Public Utilities, which receive an initial 75% incentive toward performance of the energy audit, facilities are only eligible for an additional $0.05 per square foot, up to a maximum of $25,000, rather than the standard incentive noted above. Incentive #2: Installation of Recommended Measures – This incentive is based on projected energy savings as determined in Incentive #1 (Minimum 15% savings must be achieved), and is paid upon successful installation of recommended measures. Electric
Base incentive based on 15% savings: $0.09/ per projected kWh saved. For each % over 15% add: $0.005 per projected kWh saved. Maximum incentive: $0.11/ kWh per projected kWh saved
Gas Base incentive based on 15% savings: $0.90/ per projected Therm saved.
New Jersey BPU – Parsippany-Troy Hills Board of Education- Energy Audit 19 | P a g e
For each % over 15% add: $0.05 per projected Therm saved. Maximum incentive: $1.25 per projected Therm saved
Incentive cap: 25% of total project cost Incentive #3: Post-Construction Benchmarking Report – This incentive is paid after acceptance of a report proving energy savings over one year utilizing the Environmental Protection Agency (EPA) Portfolio Manager benchmarking tool. Electric
Base incentive based on 15% savings: $0.09/ per projected kWh saved. For each % over 15% add: $0.005 per projected kWh saved. Maximum incentive: $0.11/ kWh per projected kWh saved
Gas
Base incentive based on 15% savings: $0.90/ per projected Therm saved. For each % over 15% add: $0.05 per projected Therm saved. Maximum incentive: $1.25 per projected Therm saved
Combining incentives #2 and #3 will provide a total of $0.18/ kWh and $1.8/therm not to exceed 50% of total project cost. Additional incentives for #2 and #3 are increased by $0.005/kWh and $0.05/therm for each percentage increase above the 15% minimum target to 20%, calculated with the EPA Portfolio Manager benchmarking tool, not to exceed 50% of total project cost. Total P4P incentives are summarized below:
Incentives $ Electric Gas Total
Incentive #1 $0 $0 $5,000 Incentive #2 $0 $0 $0 Incentive #3 $0 $0 $0
Total $0 $0 $5,000
For the purpose of demonstrating the eligibility of the ECM’s to meet the minimum savings requirement of 15% for the Pay for Performance Program, all recommended ECM’s have been included in the incentive calculations resulting in a 2.8% energy savings. Based on this savings, the school would not be eligible for the Pay for Performance Program. Refer to appendix D for more information on this program. 5.1.4 Energy Savings Improvement Plan (ESIP) The Energy Savings Improvement Program (ESIP) allows government agencies to make energy related improvements to their facilities and pay for the costs using the value of energy savings that result from the improvements. Under the recently enacted Chapter 4 of the Laws of 2009 (the law), the ESIP provides all government agencies in New Jersey
New Jersey BPU – Parsippany-Troy Hills Board of Education- Energy Audit 20 | P a g e
with a flexible tool to improve and reduce energy usage with minimal expenditure of new financial resources. ESIP allows local units to use “energy savings obligations” to pay for the capital costs of energy improvements to their facilities. This can be done over a maximum term of 15 years. Energy savings obligations are not considered “new general obligation debt” of a local unit and do not count against debt limits or require voter approval. They may be issued as refunding bonds or leases. Savings generated from the installation of energy conservation measures pay the principal of and interest on the bonds; for that reason, the debt service created by the ESOs is not paid from the debt service fund, but is paid from the general fund. For local governments interested in pursuing an ESIP, the first step is to perform an energy audit. Pursuing a Local Government Energy Audit through New Jersey's Clean Energy Program is a valuable first step to the ESIP approach. The “Local Finance Notice” outlines how local governments can develop and implement an ESIP for their facilities. The ESIP can be prepared internally if the entity has qualified staff. If not, the ESIP must be implemented by an independent contractor and not by the energy savings company producing the Energy Reduction Plan. The ESIP approach may not be appropriate for all energy conservation and energy efficiency improvements. Local units should carefully consider all alternatives to develop an approach that best meets their needs. Refer to appendix D for more information on this program.

This measure is not recommended due to the long payback time. It is suggested, however, that the school continue to monitor the SREC credits and evaluate the PV installation again should the SREC credit values increase. It is also important to note that a feasibility study should be performed by a third party solar contractor, before any installation takes place. 6.1.2 Solar Thermal Hot Water Generation Active solar thermal systems use solar collectors to gather the sun’s energy to heat water, another fluid, or air. An absorber in the collector converts the sun’s energy into heat. The heat is then transferred by circulating water, antifreeze, or sometimes air to another location for immediate use or storage for later utilization. Applications for active solar thermal energy include providing hot water, heating swimming pools, space heating, and preheating air in residential and commercial buildings. A standard solar hot water system is typically composed of solar collectors, heat storage vessel, piping, circulators, and controls. Systems are typically integrated to work alongside a conventional heating system that provides heat when solar resources are not sufficient. The solar collectors are usually placed on the roof of the building, oriented south, and tilted around the site’s latitude, to maximize the amount of radiation collected on a yearly basis. Several options exist for using active solar thermal systems for space heating. The most common method involves using glazed collectors to heat a liquid held in a storage tank (similar to an active solar hot water system). The most practical system would transfer the heat from the panels to thermal storage tanks and transfer solar produced thermal energy to use for domestic hot water production. DHW is presently produced by gas-fired water heaters and, therefore, this measure would offer natural gas utility savings. 6.2 Demand Response Curtailment Presently, Electricity is delivered by JCP&L, which receives the electricity from regional power grid RFC. PMJ is the regional transmission organization (RTO) that coordinates the movement of wholesale electricity in all or parts of 13 states and the District of Columbia including the State of New Jersey.
New Jersey BPU – Parsippany-Troy Hills Board of Education- Energy Audit 23 | P a g e
Utility Curtailment is an agreement with the utility provider’s regional transmission organization and an approved Curtailment Service Provider (CSP) to shed electrical load by either turning major equipment off or energizing all or part of a facility utilizing an emergency generator; therefore, reducing the electrical demand on the utility grid. This program is to benefit the utility company during high demand periods and utility provider offers incentives to the CSP to participate in this program. Enrolling in the program will require program participants to drop electrical load or turn on emergency generators during high electrical demand conditions or during emergencies. Part of the program also will require that program participants reduce their required load or run emergency generators with notice to test the system. A pre-approved CSP will require a minimum of 100 kW of load reduction to participate in any curtailment program. From November 2011 through October 2012 the facility had a peak electricity demand of 68.0 kW and a minimum of 40.8 kW. The monthly average over the observed 12 month period was 51.1 kW. This measure is not recommended because the school will be unable to meet the minimum electrical load reduction of 100 kW.
