Commissioning HVAC Performance Testing Energy Audits Project Management

Retro-Commissioning Facility Management Consulting Energy Procurement

August 4, 2010 Mr. J. Steven DiGeronimo Business Administrator / Board Secretary Pequannock Township Board of Education 538 Newark Pompton Pike Pompton Plains, New Jersey 07444 Re: EXECUTIVE SUMMARY FOR PEQUANNOCK TOWNSHIP BOARD OF EDUCATION STATE OF NEW JERSEY LOCAL GOVERNMENT ENERGY AUDIT Dear Mr. DiGeronimo: Dome-Tech was retained by the Pequannock Township Board of Education, as a pre-qualified participant in the Local Government Energy Audit Program, to perform an energy audit. The objectives of the energy audit were to evaluate the township’s energy consumption, establish baselines for energy efficiency and identify opportunities to reduce the amount of energy used and/or its cost. The scope of the audit is standardized under the Program, and consisted of the following:

Benchmarking historic energy consumption utilizing EPA Energy Star’s Portfolio Manager

Characterizing building use, occupancy, size, and construction

Providing a detailed equipment list including estimated service life and efficiency

Identifying and quantifying energy conservation measures (ECMs)

Evaluating the economic viability of various renewable/distributed energy technologies

Performing a utility tariff analysis and assessing savings potential from energy procurement strategies

Providing the method of analyses Based upon data received for the twelve month period October 2008 - October 2009, the District had an annual expenditure of:

Electricity: 2,068,360 kWh at a total cost of $342,987

Natural Gas: 285,436 therms at a total cost of $430,961 The following buildings were evaluated:

Pequannock High School at 85 Sunset Road, Pompton Plains, NJ – 137,355 SF

Pequannock Valley Middle School at 493 Newark Pompton Turnpike, Pompton Plains, NJ – 84,200 SF

North Boulevard Elementary School at 363 Boulevard, Pompton Plains, NJ – 46,908 SF

Hillview Elementary School at 206 Boulevard, Pompton Plains, NJ – 44,988 SF

Stephan J Gerace Elementary School at 59 Boulevard, Pequannock, NJ – 33,500 SF Please refer to Section 2 of this report for a detailed list of identified Energy Conservation Measures (ECMs), along with a summary of their preliminary economics (estimated project cost, estimated annual energy savings, applicable rebate(s), etc.) In this report, all identified ECMs are ranked and presented according to their simple payback; however, please note that the master ECM table can also be sorted by building, by measure type, etc.

Page 3

“Building Performance - Delivered”

If all identified ECMs were to be implemented, they would provide the following estimated benefits to Pequannock Township Board of Education:

Total annual electrical savings: 870,935 kilowatt-hours; 42%

Total annual natural gas savings: 56,640 therms of natural gas usage; 20%

Total annual cost savings: $229,250; 29%

Total annual CO2 emissions reduction: 619 tons

Total net estimated implementation cost: $1,268,150

Total average simple payback: 2.2 years The projects that are recommended for implementation (at all facilities) include: Upgrading the lighting, pipe insulation, and, select equipment upgrades, installing vending machine power management devices, and implementing energy awareness programs. The district data was entered into the US EPA ENERGY STAR’s Portfolio Manager database program. The buildings ranged from 1 to 12 scores. Buildings with scores of 75 or higher may qualify for the ENERGY STAR Building Label. Please see report for individual facility scores. Distributed/Renewable Energy Systems were reviewed with the following conclusions:

Dome-Tech considered three different types of wind turbine technologies that consisted of both building-mounted and traditional ground-mounted variety. Due to attractive payback and high potential for energy reduction, the 50 kilowatt ground-mounted wind turbine project appears to be the most attractive option. Should Pequannock Township Board of Education decide to pursue a wind turbine project, Dome-Tech recommends commissioning a more detailed study.

Roof-mounted 54 - 481 kw dc photovoltaic systems that could provide 25 -95% per building of the District’s annual energy usage were assessed for implementation.

Combined Heat & Power (CHP), Fuel Cells, and Micro-turbines were also researched, but are not recommended due to the lack of thermal requirements in the summertime.

Regarding the procurement of retail energy, Dome-Tech understands that the Pequannock Township Board of Education facilities are served by five electric accounts behind JCP&L, under General Secondary Service 3 Phase rate class. Additionally natural gas is served by five accounts behind PSE&G Large Volume Gas (LVG) rate class. Dome-Tech understands that Pequannock Township Board of Education accounts are currently not contracted with a retail energy supplier. Now is an ideal time to seek longer-term rate stability through a fixed price arrangement through a retail supplier.

During the development of this audit, Dome-Tech was assisted by facility personnel, who were both knowledgeable and very helpful to our efforts. We would like to acknowledge and thank those individuals. Sincerely, John Butterly Senior Energy Engineer

Greenhouse Gas Emission Reduction

Implementation of all the identified ECMs will yield:

870,935 kilowatt-hours of annual avoided electric usage.

47,170 therms of annual avoided natural gas usage.

This equates to the following annual reductions:

619 tons of CO2;

-OR-

107 Cars removed from road;

-OR-

169 Acres of trees planted annually

The Energy Information Administration

(EIA) estimates that power plants in

the state of New Jersey emit 0.666 lbs

CO2 per kWh generated.

The Environmental Protection Agency

(EPA) estimates that one car emits

11,560 lbs CO2 per year.

The EPA estimates that reducing

CO2 emissions by 7,333 pounds

is equivalent to planting an acre of

trees.

Notes and Assumptions

Project cost estimates were based upon industry accepted published cost data, rough order of

magnitude cost estimates from contractors, and regional prevailing wage rates. The cost estimates

presented in this report should be used to select projects for investment grade development. The cost

estimates presented in this report should not be used for budget development or acquisition requests.

Estimated energy and cost savings are based on individual projects being implemented and do not

account for potential synergies if multiple projects are implemented concurrently. Therefore, cumulative

energy and cost savings shown in this report may or may not be representative of actual results.

The average CO2 emission rate from power plants serving the facilities within this report was obtained

from the Environmental Protection Agency’s (EPA) eGRID2007 report. It is stated that power plants

within the state of NJ emit 0.66 lbs of CO2 per kWh generated.

The EPA estimates that burning one therm of natural gas emits 11.708 lbs CO2.

The EPA estimates that one car emits 11,560 lbs CO2 per year.

The EPA estimates that reducing CO2 emissions by 7,333 pounds is equivalent to planting an acre of trees.

Energy Conservation Measure (ECM) #1: Install Destratification Fans in High Bays for Winter Use

The gyms are heated by fan coil units suspended from the ceilings. This can result in a

significant temperature difference between floor to ceiling levels.

The heating system consumes additional energy due to this stratification occurring in

these large spaces. When the system cycles off, the heated air rises to the ceiling and

the cooler air sinks to the floor. The thermostat, at the lower level, senses the cooler

temperature and cycles the system back on. Setpoint is not achieved until the air near

the ceiling is significantly warmer than the lower levels.

Destratification fans would gently distribute the heat trapped at the ceiling down to the

floor, creating a more uniform temperature throughout the space, therefore reducing the

amount of energy needed to reach setpoint.

ECM #2: Install / Upgrade Pipe Insulation (on Pump Casings and Valves)

Some facilities have missing insulation around heating hot water and domestic hot water pumps and valves in the boiler rooms.

Boilers will have to cycle more to maintain the temperature set point. Also tempered air is exiting the room through the outside air vents.

Dome-Tech recommends insulating the exposed domestic hot water and boiler pipes and equipment.

ECM #3: Vending Machine Power Management

Dome-Tech recommends installing a VendMiser vending machine power

management device on all vending machines.

The device uses a passive infrared sensor to power down the machine when the

area surrounding it is vacant. Then it monitors the room’s temperature and

automatically re-powers the cooling system at one- to three-hour intervals,

independent of sales, to ensure that the product stays cold.

The microcontroller will never power down the machine while the compressor is

running, eliminating compressor short-cycling. In addition, when the machine is

powered up, the cooling cycle is allowed to finish before again powering down

(reduces compressor wear and tear).

ECM #6: Lighting Upgrade

Although most of the current light fixtures have first generationT-8 fluorescent lamps and ballasts, improved lamp designs will further reduce lighting energy costs. The gyms have older technology HID lighting and should be retrofitted with High Output T5 fixtures.

Many areas were observed to have lights on regardless of occupancy. Installing occupancy sensors in these areas will automatically turn lights on/off according to actual occupancy by sensing the presence of people in the room. Occupancy sensors will reduce lighting energy costs by approximately 30%*.

ECM #7: Replace Boilers with High Efficiency Modulating Condensing Boilers

Many of the schools are equipped with natural gas fired hot water or steam boilers in variousconfigurations of one or more units. In most cases, the steam is converted to hot water before it isdistributed to the end users.

For the most part, these boilers are old and are nearing the end of the equipment service life (ASHRAEstates the service life of similar equipment to be 25 years).

The ages, sizes, types and configurations of the boilers do not lend themselves to efficient operation.Generally, as boilers approach the end of their service life, the efficiency degrades and the boiler mustconsume more fuel in order to produce the same rated output. In addition, there is a direct correlationbetween risk of equipment failure (tube breaks & meltdown, shell cracks, furnace surface area failure)and equipment age.

If the existing boilers could be replaced by high efficiency, modulating or modular condensing boilers,savings will be realized in two ways. Modulating boilers, usually 1,000 MBH or smaller, employ multiple burners to meet the heating load. Each burner

operates independently, eliminating the “all on/all off” operation of single burner boilers. As building loadincreases only those burners necessary to meet the load are fired. This allows each burner to run at optimalefficiency. Modular boilers operate under the same principal but for larger installations. In this case multipleboilers are used rather than multiple burners. Modular boilers usually are employed in 1000, 2000 or 3000 MBHsizes.

Condensing boilers recover energy from the exhaust gas thus allowing high efficiencies of 90% and above.

When a boiler is both a modulating/modular type and a condensing type, extremely high efficienciescan be realized.

ECM #7: Replace Boilers with High Efficiency Modulating Condensing Boilers (continued)

The high first cost of a new boiler system may preclude this ECM from being justified by economicsalone at some of the facilities. The ECM table details the economics at each site. However, reliabilityissues warrant consideration of these projects as part of a long-term capital improvement plan.

NOTE: The presented economics should be used for planning purposes only. If the client decides to proceed with any boiler replacement project,

these economics should be refined with an investment grade analysis.

ECM #10: Implement Demand Control Ventilation in Library & Auditorium

Building codes require that a minimum amount of fresh air be provided to ensure adequate airquality. To comply, ventilation systems often operate at a fixed rate based on an assumedoccupancy (e.g., 20 cfm per person multiplied by the maximum design occupancy). The result isexcessive fresh air volumes which require costly (and unnecessary) conditioning.

Demand-controlled ventilation controls the amount of outside air based upon the CO2 levels

generated by building occupants. Demand ventilation should be added to any return air system

where space occupancy varies dramatically. Dome-Tech recommends DCV controls for the

auditorium and library HVAC units.

By installing CO2 sensors and controlling the CO2 level at less than 1000 PPM, the outside air

flow is kept to the absolute minimum while space conditions are kept in compliance with building

codes and standards such as the ASHRAE Indoor Air Quality Standard.

ECM #12: Walk-In Cooler Controllers

Typically the walk-in cooler evaporator fans run continuously.

However, full airflow is only required 50% of the runtime.

In the most common applications (those that use single-phase

power), motors for the fans are typically shaded-pole or

permanent-split-capacitor types, both of which are very inefficient.

Inexpensive controllers are currently available that slow these

fans when full-speed operation is unnecessary.

Reducing the operating speed reduces the energy consumption of

the fan. In addition, the motor produces less heat at slower

speeds, which means that the compressor has less heat to

remove from the refrigerated compartment.

Renewable/Distributed Energy Measures

Distributed Generation & Renewable Energy

Distributed Generation (on-site generation) generates electricity from many small energy sources. These sources can be renewable (solar/wind/geothermal) or can be small scale power generation technologies (CHP, fuel cells, microturbines)

Renewable energy is energy generated from natural resources (sunlight, wind, and underground geothermal heat) which are naturally replenished

Photovoltaics (solar) are particularly popular in Germany and Spain and growing in popularity in the U.S.

Wind power is growing as well, mostly in Europe and the U.S.

Page 40


Renewable Energy Technologies: Wind

Wind turbines generate electricity by harnessing a wind stream's kinetic energy as it spins the turbine airfoils. As with most renewable energy sources, wind

energy is subject to intermittent performance due to the unpredictability of wind resources.

Pequannock Township Wind Speed

As previously stated, wind speed is critical to the successful wind turbine installation. According to average wind data from NASA’s Surface Meteorology and

Solar Energy records, the average annual wind speed for the Pequannock area is 5.3 meters per second. Ideal wind speeds for a successful project should

average over 6 meters per second.

For Pequannock Township, Dome-Tech considered three (3) types of wind turbine technologies; building integrated wind turbines (1 kW each) and traditional

ground mounted wind turbines (5 kW & 50 kW).

Renewable Energy Technologies: Solar Photovoltaic

Solar Photovoltaic

Sunlight can be converted into electricity using photovoltaics (PV).

A solar cell or photovoltaic cell is a device that converts sunlight directly into electricity.

Photons in sunlight hit the solar panel and are absorbed by semiconducting materials, such as silicon. Electrons are knocked loose from their atoms, allowing them to flow through the material to produce electricity.

Solar cells are often electrically connected and encapsulated as a module, in series, creating an additive voltage. The modules are connected in an array. The power output of an array is measured in watts or kilowatts, and typical energy needs are measured in kilowatt-hours.

Can be recommended in this application for placement on additional schools / areas.

Non-Financial Benefits of Solar PV The implementation of solar PV projects at

Pequannock Township School District would

place your facilities at the forefront of

renewable energy utilization. This allows the

District the opportunity to not only gain

experience with this energy technology, but

also to win recognition as an environmentally

sensitive, socially conscience institution.

Additionally, these projects could be

incorporated into science education and

additional curriculums to raise awareness of

current energy alternatives to the younger

Renewable Energy Technologies: CHP/Cogeneration

CHP (combined heat and power) or cogeneration is the use of a heat engine to simultaneously generate both electricity and useful heat.

Fuel Cells are electrochemical conversion devices that operate by catalysis, separation the protons and the electrons of the reactant fuel, and forcing the electrons to travel through a circuit to produce electricity. The catalyst is typically a platinum group metal or alloy. Another catalytic process takes the electrons back in, combining them with the protons and oxidant, producing waste products (usually water and carbon dioxide).

Microturbines are rotary engines that extract energy from a flow of combustion gas. They can be used with absorption chillers to provide cooling through waste heat rather than electricity. Microturbines are best suited for facilities with year-round thermal and/or cooling loads.

Not recommended for Pequannock Township Schools due to the lack of thermal requirements in the summertime.

Utility Deregulation in New Jersey: Background and Retail Energy Purchasing

In August 2003, per the Electric Discount and Energy Competition Act [N.J.S.A 48:3-49], the

State of New Jersey deregulated its electric marketplace thus making it possible for customers

to shop for a third-party (someone other than the utility) supplier of retail electricity.

Per this process, every single electric account for every customer in New Jersey was placed

into one of two categories: BGS-FP or BGS-CIEP. BGS-FP stands for Basic Generation

Service-Fixed Price; BGS-CIEP stands for Basic Generation Service-Commercial and

Industrial Energy Pricing.

At its first pass, this categorization of accounts was based on rate class. The largest electric

accounts in the State (those served under a Primary or a Transmission-level rate class) were

moved into BGS-CIEP pricing. All other accounts (the vast majority of accounts in the State of

New Jersey, including residential) were placed in the BGS-FP category, receiving default

electric supply service from the utility.

The New Jersey Board of Public Utilities (NJBPU) has continued to move new large energy

users from the BGS-FP category into the BGS-CIEP category by lowering the demand (kW)

threshold for electric accounts receiving Secondary service. Several years ago, this threshold

started at 1,500kW; now, it has come down to 1,000 kW. So, if an account’s “peak load share”

(as assigned by the utility) is less than 1,000 kW, then that facility/account is in the BGS-FP

category. If you are unsure, you may contact Dome-tech for assistance.

Page 53


Utility Deregulation in New Jersey: Background and Retail Energy Purchasing (cont.)

There are at least 3 important differentiating factors to note about each rate category:

1. The rate structure for BGS-FP accounts and for BGS-CIEP accounts varies.

2. The “do-nothing” option (ie, what happens when you don’t shop for retail energy) varies.

3. The decision about whether, and why, to shop for a retail provider varies.

Secondary (small to medium) Electric Accounts:

o BGS-FP rate schedules for all utilities are set, and re-set, each year. Per the results of our State’s BGS

Auction process, held each February, new utility default rates go into effect every year on June 1st. The

BGS-FP rates become each customer’s default rates, and they dictate a customer’s “Price to Compare”

(benchmark) for shopping purposes. To learn more about the BGS Auction process, please go to

www.bgs-auction.com.

o A customer’s decision about whether to buy energy from a retail energy supplier is, therefore, dependent

upon whether a supplier can offer rates that are lower than the utility’s (default) Price to Compare. In

2009, and for the first time in several years, many BGS-FP customers have “switched” from the utility to

a retail energy supplier because there have been savings. This may be the same case in 2010.

Primary (large) Electric Accounts:

o The BGS-CIEP category is quite different. There are two main features to note about BGS-CIEP

accounts that do not switch to a retail supplier for service. The first is that they pay an hourly market

rate for energy; the second is that these accounts also pay a “retail margin adder” of $0.0053/kWh. For

these large accounts, this retail adder can amount to tens of thousands of dollars. The adder is

eliminated when a customer switches to a retail supplier for service.

o For BGS-CIEP accounts, the retail adder makes a customer’s decision about whether to switch

relatively simple. However, the process of setting forth a buying strategy can be complex, which is why

many public entities seek professional assistance when shopping for energy.

Utility Deregulation in New Jersey: Background and Retail Energy Purchasing (cont.)

Natural Gas Accounts:

o The natural gas market in New Jersey is also deregulated. Unlike the electric market, there are no

“penalties”, or “adders”, for not shopping for natural gas. Most customers that remain with the utility for

natural gas service pay rates that are market-based and that fluctuate on a monthly basis. While natural

gas is a commodity that is exceptionally volatile and that is traded minute-by-minute during open trading

sessions, market rates are “settled” each month, 3 business days prior to the subsequent month (this is

called the “prompt month”). Customers that do not shop for a natural gas supplier will typically pay this

monthly settlement rate to the utility, plus other costs that are necessary to bring gas from Louisiana up

to New Jersey and ultimately to your facility.

o For additional information about natural gas trading and current market futures rates for various

commodities, you can refer to www.nymex.com.

o A customer’s decision about whether to buy natural gas from a retail supplier is typically dependent

upon whether a customer seeks budget certainty and/or longer-term rate stability. Customers can

secure longer-term fixed prices by enlisting a retail natural gas supplier. Many larger natural gas

customers also seek the assistance of a professional consultant to assist in their procurement process.

Retail Energy Purchasing: Recommendations and Resources

Electric

o Based on current and recent market conditions, and actual bid processes run by Dome-Tech for various

clients during spring of 2010, we have seen customers with BGS-FP accounts save approximately 10-

20% in projected energy costs by switching to retail energy supplier. The District could secure this type

of agreement, this could represent an annual savings of approximately $50,000 for the larger accounts

at the District. It is important to note that actual rates and potential savings will be dependent on several

factors, including market conditions, account usage characteristics/load profile (load factor), volume, and

contract term.

Natural Gas

o Based on current and recent market conditions, and actual bid processes run by Dome-Tech for various

clients during spring of 2010, we have seen many customers entering into longer-term contracts for

fixed natural gas rates. These rates vary substantially based on load type, volume, and term. For the

period studies, the District was utilizing Hess Corporation as a third party supplier for natural gas a fixed

rate averaging $1.20 per therm.

Energy Purchasing Co-Operatives

Many public entities participate in various energy aggregation buying groups. Sometimes, an entity will

have multiple options to choose from. These might include purchasing through a County co-operative,

or purchasing through a trade-type association (for instance, many schools participate in NJASBO’s

ACES program). Co-operative purchasing may not necessarily get you the lowest rates; however, there

is often substantial volume, and it can represent a good alternative for entities with limited energy

consumption who can have a difficult time getting energy suppliers to respond to them on a direct,

singular basis.

To determine whether a savings opportunity currently exists for your entity, or for guidance on how to get

started, you may contact Dome-Tech to discuss. There is also additional information provided below.

Historical Energy Futures Settlement Prices

Below please find graphs that show the last several years’ worth of market settlement prices for both natural gas and

electricity. Each of these graphs shows the average closing prices of a rolling 12-month period of energy futures

prices. The graphs are representative of the commodity, alone; they do not include any of the additional components

(capacity, transmission, ancillary services, etc.) that comprise a retail energy price. They are meant to provide an

indication of the level of pricing that a particular customer might expect to see, but the graphs do not account for the

specific load profile of any individual energy user.
