Mr. L. Douglas Pechanec Business Administrator/Board Secretary West Morris Regional High School District Administration Building 10 South Four Bridges Road Chester, NJ 07930 Re: EXECUTIVE SUMMARY FOR WEST MORRIS REGIONAL HIGH SCHOOL DISTRICT STATE OF NEW JERSEY LOCAL GOVERNMENT ENERGY AUDIT Dear Mr. Pechanec: Dome-Tech was retained by the West Morris Regional High School District, 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 District’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 May 2009 - May 2010, the District had an annual expenditure of:
Electricity: 3,941,116 kWh at a total cost of $612,441
Natural Gas: 226,924 therms at a total cost of $254,242 The following buildings were evaluated:
West Morris Central High School at 259 Bartley Road, Chester, NJ – 212,000 SF
West Morris Mendham High School at 65 ½ E. Main Street, Mendham, NJ – 198,000 SF
West Morris Regional Board Office at 10 South Four Bridges Road, Chester, NJ – 4,000 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 West Morris Regional High School District:
Total annual electrical savings: 801,630 kilowatt-hours; 20%
Total annual natural gas savings: 34,460 therms of natural gas usage; 15%
Total annual cost savings: $158,730; 18%
Total annual CO2 emissions reduction: 466 tons
Total net estimated implementation cost: $547,790
Total average payback on net implementation cost: 3.5 years The projects that are recommended for implementation (at all facilities) include: Upgrading the lighting, select equipment upgrades, replacing boilers, installing fan speed controllers on univents and other equipment, 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 55 to 65 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 West Morris Regional High School District decide to pursue a wind turbine project, Dome-Tech recommends commissioning a more detailed study.
The District currently has existing plans for implementation of rooftop solar PV systems through a Morris County program. Dome-Tech examined installing additional systems over the parking lots. These additional parking lot systems could generate approximately half of each school’s annual power consumption.
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 West Morris Regional High School District facilities are served by eleven 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) and General Service Gas (GSGH) rate classes. Dome-Tech understands that West Morris Regional High School District accounts are currently not contracted with an electric retail energy supplier and New Jersey Natural Gas for natural gas 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, PE, CEM, CEA Senior Energy Engineer

Greenhouse Gas Emission Reduction
Implementation of all the identified ECMs will yield:
776,850 kilowatt-hours of annual avoided electric usage.
34,460 therms of annual avoided natural gas usage.
This equates to the following annual reductions:
466 tons of CO2;
-OR-
81 Cars removed from road;
-OR-
127 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.
Page 18
West Morris Regional High School District, Chester, NJ FINAL Energy Audit Report, September 2010
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 #1: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).

Central high school’s kitchen is equipped with a 4 element
electric stove.
The school’s electric cost is over $0.15 per kilowatt hour. The
equivalent natural gas cost is $5.101 per therm (assuming a
95% efficient natural gas unit). The actual price for natural
gas is approximately $1.223 per therm (less than 1/3 the price
of electric on a Btu basis).
Replacing the electric stove at the end of its service life with a
natural gas unit will provide about $360 in annual savings.Electric Stove Fuel Switch

ECM # 3: 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. Some of 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 # 5: Upgrade Kitchen Appliances with Energy Star Models
* Note: Avoided Cost = Cost of Like and Kind replacement
Some of the kitchen equipment at the High Schools (specifically reach-in refrigerators,
dish washers and ice machines) is older and less efficient than newer models.
Replacing this equipment with higher efficiency, Energy Star labeled equipment will
provide at least $10,000 in annual savings.
Improvements in kitchen equipment include lower idle rates, better insulation which
reduces the amount of standby losses through sides and top, and premium efficiency
compressor and fan motors.

ECM # 6: Replace Boilers with High Efficiency Modular/Modulating Condensing Boilers
Mendham High School is equipped with two Weil-McClane cast iron, natural gas fired, hot waterboilers located in the original building’s MER.
These boilers are approximately 15 years old and are half way to the end of the equipment service life(ASHRAE states 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 age, the efficiency degrades and the boilers must consume more fuel in order toproduce the same rated output. In addition, there is a direct correlation between risk of equipmentfailure (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 burneroperates 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.
The new Fulton Pulse boilers installed at Mendham High and the Aerco boilers at Central High areexamples of the equipment recommended by this ECM

Some of the existing rooftop units (RTUs) are near or beyondthe end of their estimated equipment service life (EESL) perASHRAE standards. (The EESL for package rooftop units is15 years.)
Replacing these RTU’s with new, higher efficiency units willsignificantly reduce annual energy and maintenance costs.

ECM # 8: 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.

West Morris Regional High School District currently has no observed program in place.
Educational institutions are where our nation’s youth spend a significant portion of their
time. As such, educators can have a potentially large impact on promoting an energy
conscious and conservation-minded society that starts at their school, leading to energy
cost reductions, environmental benefits, and national energy independence.
In addition, schools can receive recognition for their efforts and possible media coverage,
which can contribute to enhanced school spirit, and individual feelings of accomplishment

Operations and Maintenance Items
Icing and deteriorated insulation on refrigerant lines:
Condition:
Dome-Tech noticed several AC refrigerant supply lines with deteriorated or missing insulation.
Issue:This results in the compressor having to expend more energy to overcome the heat gain suffered by the exposed supply lines.
In some cases, icing is occurring which could indicate low refrigerant levels.
Solution:
WM RHS District should implement an annual inspection program for all refrigerant lines. Missing insulation should be replaced. Foam insulation should be protected from UV damage by a coating of exterior latex paint.
Any icing, leaks or other problems should be investigated and corrected.

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 33
West Morris Regional High School District, Chester, NJ FINAL Energy Audit Report, September 2010
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.
Chester 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 Chester/ West Morris area is 5.0meters per second. Ideal wind speeds for a successful
project should average over 6 meters per second.
For Chester, 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.

West Morris RHS BOE
West Morris RHS BOE is participating in Morris County’s solar PV program which will result in the installation of sizable PV systems on each of the two high schools’ roofs.
Accordingly, Dome-Tech did not assess roof-top solar PV systems at the schools. However, the BOE requested Dome-Tech estimate how much additional solar power could be generated by PV systems on structures installed over the parking lots (a.k.a. “carport PV systems”).
The following tables contain the results of these analyses. Details including the areas considered appropriate for installation are included in the appendices.
Note that these figures are based on estimated placement and configuration of the PV systems. Actual site-specific engineering could significantly change the location and/or the generating capacity of the final design.
Best practices dictate that PV systems should not be designed to produce more kWh than a site consumes annually. The capacity of the rooftop PV systems installed by the County could effect the size of any PV systems installed over the parking lots.

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.
CHP is not recommended for West Morris Regional High School District 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 45
West Morris Regional High School District, Chester, NJ FINAL Energy Audit Report, September 2010
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.
o For more information concerning hourly electric market prices for our region, please refer to
www.pjm.com.

West Morris Regional High School District, Chester, NJ FINAL Energy Audit Report, September 2010
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 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 $61,000 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. For the period studied, the District utilized South Jersey Energy as a third party supplier
for electricity.
Natural Gas
o Based on current and recent market conditions, and actual bid processes run by Dome-Tech for various
clients during 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 studied,
the District was not utilizing a third party supplier for natural gas.
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,

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.

Potential Project Funding Sources
Through the NJ Clean Energy program, the New Jersey Board of Public Utilities currently
offers a variety of subsidies or rebates for many of the project types outlined in this report.
More detailed information can be found at: www.njcleanenergy.com
NJ Smart Start Buildings – Equipment Rebates noted in ECMs where available.Equipment Rebates - Water Heaters, Lighting, Lighting Controls/Sensors, Chillers, Boilers, Heat
pumps, Air conditioners, Energy Mgmt. Systems/Building Controls, Motors, Motor-ASDs/VSDs,
Custom/Others http://www.njcleanenergy.com/commercial-industrial/programs/nj-smartstart-
buildings/nj-smartstart-buildings
Pay for Performance Program – Performance-Based Incentives for installations.
Provides up to 50% of total project costs. Based on findings in this study, up to $550,000 in
incentives for project implementation could be provided under this program. A minimum
reduction target of 15% compared to baseline must be achieved. Energy modeling of building and
systems and energy reduction plan is required (incentives provided to pay for part of study costs.)
Energy Savings Improvement Program (ESIP) Public entities can contract with energy
serving companies in up to 20-year lease purchases enabling public entities to implement energy
conservation measures to their facilities and pay for the costs using the value of energy savings that
result from the improvements. www.nj.gov/dca/lgs/lfns/09lfns/2009-11.doc

Potential Project Funding Sources (continued)
Clean Energy Solutions Capital Investment Loan/GrantThe EDA offers up to $5 million in interest-free loans and grants to promote the concept of "going
green" in New Jersey. Under this program, scoring criteria based on the project's environmental and
economic development impact determines the percentage split of loan and grant awarded. Funding
can be used to purchase fixed assets, including real estate and equipment, for an end-use energy
efficiency project, combined heat and power (CHP or cogen) production facility, or new state-of-the-art
efficient electric generation facility, including Class I and Class II renewable Energy.
