Commissioning HVAC Performance Testing Energy Audits Project Management

Retro-Commissioning Facility Management Consulting Energy Procurement

April 18, 2011 Mr. Robert Davis Interim Business Administrator Hoboken Board of Education 1115 Clinton Street Hoboken, NJ 07030 Re: EXECUTIVE SUMMARY FOR HOBOKEN BOARD OF EDUCATION STATE OF NEW JERSEY LOCAL GOVERNMENT ENERGY AUDIT Dear Mr. Davis: Dome-Tech was retained by Hoboken Board of Education, as a pre-qualified participant in the Local Government Energy Audit Program, to perform an energy audit. The objective of the energy audit was 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 (12) month period January 2010 – December 2010, for the facilities included in this study, the District had an annual expenditure of:

Electricity: 4,033,523 kWh at a total cost of $ 710,191

Natural Gas: 262,038 therms at a total cost of $ 327,573

The following six (6) buildings were evaluated under this study:

Calabro Elementary School 30,750 SF

Connors Elementary School 60,265 SF

Wallace Elementary School 122,300 SF

Brandt Elementary School 77,945 SF

Demarest Middle School 82,435 SF

Hoboken High School 193,780 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. If all identified ECMs were to be implemented, they would provide the following estimated benefits to the Hoboken Board of Education:

Total annual electrical savings: 1,616,965 kilowatt-hours; 40%

Total annual natural gas savings: 39,695 therms of natural gas usage; 15%

Total annual cost savings: $301,890; 29%

Total annual CO2 emissions reduction: 766 tons

Total net estimated implementation cost: $5,088,655

Total average simple payback: 16.9 years A summary of the projects that are recommended for implementation (at all facilities) includes: installing vending machine and personal computer power management devices; implementing a steam trap preventative maintenance program; replacing electric water heaters with gas fired units; removing and weatherizing unused skylights; upgrading tank and piping insulation, upgrading lighting; replacing equipment and control systems; retail energy purchasing; and implementing an energy awareness program. Please see the report for a full list of recommended ECM’s. The District’s data was entered into the US EPA ENERGY STAR’s Portfolio Manager database program. Buildings with scores of 75 or higher may qualify for the ENERGY STAR Building Label. For the District’s buildings that were eligible for an Energy Star score, the scores ranged between 34 and 65. (Wallace score is 100 but that is due to missing utility information and is incorrect). In order to receive an Energy Star rating, more than 50% of a building must be defined by one of the following space types: Bank/Financial Institution, Courthouse, Hospital (Acute Care and Children's), Hotel, K-12 School, Medical Office, Office, Residence Hall/Dormitory, Retail Store, Supermarket, Warehouse (Refrigerated and Non-refrigerated), Wastewater Treatment Plant, or Data Center. Some of the buildings were not eligible for a score; as an alternate, the average Source EUI was provided. Please see the report for individual facility information. 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. Ground Mounted is not possible for these buildings due to space constraints and the surrounding buildings. The Building-mounted wind turbine project appears to be the only technically viable option but we would not recommend it due to payback and high noise concerns. Should the District decide to pursue a wind turbine project, Dome-Tech recommends commissioning a more detailed study.

Roof-mounted photovoltaic systems, ranging in size from 39 - 242 kw dc, could provide approximately 15% of the District’s annual energy usage.

CHP (Combined Heat and Power), Fuel Cells, and Micro-turbines were also considered and not recommended for any of the buildings.

Page 4

Regarding the procurement of utilities, Dome-Tech understands that the Hoboken Board of Education facilities in this study are served by nine electric accounts seven natural gas accounts, all behind PSE&G. Dome-Tech understands that the District is currently under third part electric contract with a retail energy supplier for natural gas but not electric. Dome-Tech can assist the District with securing a retail electric provider, which will generate approximately $60-$80,000 in annual savings with no out-of-pocket cost.

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, Bang Duong, CEM Energy Engineer

ENERGY STAR SCORES

Energy Star Score is calculated to establish a facility-specific energy intensity baseline.

Energy Star can be used to compare energy consumption to other similar facilities and to gauge the

success of energy conservation and cost containment efforts.

Buildings with an Energy Star rating/score of 75, or above, are eligible to apply for an official Energy Star

Building label.

Due to inefficient HVAC design of the High School , Wallace School and DeMarest School and older

outdated HVAC units, it will be difficult for these buildings to achieve the energy star label. Calabro, Connors

and Brandt School’s Energy Star score is close to reaching the minimum requirements for the Energy Star

Label. After implementing some energy conservation measures listed in this this report, the school’s energy

star score should improve.

Greenhouse Gas Emission Reduction

Implementation of all identified ECMs will yield:

1,616,965 kilowatt-hours of annual avoided electric usage.

39,695 therms of annual avoided natural gas usage.

This equates to the following annual reductions:

766 tons of CO2;

-OR-

133 Cars removed from road;

-OR-

209 Acres of trees planted annually

The Energy Information Administration

(EIA) estimates that power plants in

the state of New Jersey emit s 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.

ECM #1: Optimize and Standardize the Space Temperature Setpoints

In the Calabro School, the BMS space temperature setpoints were all set to

approximately 72°F, however, the local thermostats in each space are actually

controlling the space temperature as revealed by a functional test of RTU C-139.

18 RTUs and 6 fan coil units were identified through a BMS review to be overheating

their associated spaces, thus unnecessarily increasing HVAC conditioning costs.

The BMS screenshot of RTU 129 shows a BMS temperature setpoint of 69°F, however,

due to the local thermostat setpoint of 86°F, the RTU is still in heating mode with the

space temperature at 74.5°F.

Dome-Tech recommends locking out the local thermostats and operating with the BMS

setpoints.

ECM #2: Vending Machine Power Management

Dome-Tech recommends installing a 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 #3: Time of Day Optimization

A review of the BMS time of day schedules revealed an opportunity to significantly reduceHVAC operating hours and costs.

Many of the HVAC units currently operate from 6am to 6pm, however, the classrooms arenot occupied that entire period of time. Optimizing the schedules to better reflect actualbuilding occupancy hours will reduce heating and cooling conditioning costs, electricalmotor costs and have no impact on the indoor air quality during the school days.

These savings can easily be achieved by adjusting the BMS time of day schedules.

ECM #4: Computer Power Management System

According to staff, the majority of the district’s computers are left on continuously, wasting unnecessary

energy.

Installing a computer power management system will allow IT administrators to reduce per-PC operating

cost by reducing energy consumption via shutdown, standby and hibernate for PC’s and sleep for monitors.

Additionally, the software has the capability to set up profiles to optimize time of day schedules as well as

enhance network security and improve the success rate of network maintenance task by ensuring that PC’s

are accessible when IT needs them to be.

The capability of having an on-demand network-wide shutdown protects against virus outbreak or an

imminent power outage. Similarly, shutting down unattended PCs (whether logged onto or not) after

operating hours can help protect against unauthorized access to the PCs’ data or to network resources.

Approximate average annual electric consumption of computer components: PC Only: 120 kWh @ $0.15 per kWh = $18 per year

Monitor Only: 120 – 150 kWh @ $0.15 per kWh = $ 18 – 23 per year

Combined PC and Monitor: 200 kWh @ $0.15 per kWh = $30 per year

Page 31


ECM #5: Demand Controlled Ventilation

Building codes require that a minimum amount of fresh air be provided to ensure adequate air quality. To

comply, ventilation systems often operate at a fixed rate based on an assumed occupancy (e.g., 20 CFM

per person multiplied by the maximum design occupancy). Since maximum design occupancy is rarely

achieved, this results in excessive fresh air volumes which require costly and unnecessary conditioning.

Demand-controlled ventilation (DCV) controls the amount of outside air being supplied based upon the

CO2 levels generated by building occupants. DCV should be added to any space that is ventilated by a

large quantity of outdoor air, and where occupancy varies dramatically (High School- Auditorium and

Calabro – Multi-Purpose Room).

Because CO2 levels correlate directly with the number of people in an occupied zone, CO2 sensors will

be used to control ventilation rate of outside air supplied to each zone. Reducing the amount of outdoor

air supplied to a zone reduces the energy required to heat and cool that air, while space conditions are

kept in compliance with building codes and standards such as the ASHRAE Indoor Air Quality Standard.

ECM #6: Steam Trap Maintenance Program

Steam traps that have failed open or leaking seats were located in a number of schools (as evident by

condensate receiver temperatures above 212oF).

Steam traps that leak or are failed open allow live steam to escape into the condensate system. Heat

energy from the live steam is lost to the atmosphere at the condensate receiver.

Staff indicate that steam traps are only checked when a cold complaint is received (when traps are

“failed closed”). There is no ongoing preventative maintenance or survey program.

A steam trap survey will identify the type, size, equipment served, and location of each steam trap; and

indicate the operating status: failed closed, failed open, leaking seat, or normal. Traps identified as

failed or leaking can be replaced. The survey should be performed as part of a preventative

maintenance program on an annual basis.

There are an estimated 267 steam traps in the four steam-heated elementary schools.

ECM #7: Pool Pump VFD

High School

Estimated Annual Energy Savings: $5,470






The indoor pool has a circulation pump that is sized for 4 hours per turnover. The NJ StateSanitary Code requires a turnover rate of 8 hours per turnover or less.

The pool pump operates at constant speed, 24 hours per day, 365 days per year. Openhours for the pool are approximately: Mon-Fri 7 A.M. - 4:00 P.M.; Hours also varythroughout the year, depending on the school and city’s needs.

By installing a VFD on the pool pump, facilities staff can reduce the pump speed duringunoccupied hours to the minimum flow rate required to meet the state sanitary coderequirements. The existing flow rate can be maintained during occupied hours.

ECM #8: Install Timers on Domestic Hot Water Heaters

Electric domestic hot water (DHW) heaters are enabled 24/7 during the cooling season.

There is minimal call for hot water at night.

The electric water heaters should have timers installed to eliminate standby heat loss.

ECM #11: Holiday Time of Day Optimization

Calabro School







A review of the Building Management System (BMS) time of day schedulesrevealed that no holiday schedules are programmed.

Unless the facility already manually shuts down all the HVAC equipment, theyare operating unnecessarily during school holidays. This increases HVACconditioning costs as well as electrical motor operating costs.

These savings can easily be achieved by programming the BMS holidayschedules to unoccupied mode and applying it to holidays in the BMS.

ECM #17: Lighting Upgrade

Although most of the current light fixtures have the older T-12 fluorescent lamps and ballast, improved light fixture designs will further reduce lighting energy costs by retrofitting to a lower wattage lighting system and fixtures while maintaining the minimum lighting output as per state codes. The gym’s 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%*.

High School

Estimated Annual Energy Savings: $1,530






Open hours for the pool are approximately: Mon-Fri 7 A.M. - 4:00 P.M. Hours also varythroughout the year, depending on the school and city’s needs.

There is a significant amount of heat loss through the water’s surface. Energy savings canbe realized if a pool cover is installed.

If the Board of Education decides to pursue this ECM, a further retro-commissioning studyshould be performed, there are no dedicated air handling units to maintain proper humiditylevels. The high levels of humidity that may lead to indoor air quality issues (IAQ). Adding acover will reduce evaporative losses and therefore could lower humidity levels.

Page 47


ECM #20: 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.

The perimeter hot water system is equipped with a hot water supply pump outlined below. This pump operates in online / standby mode.

The pump runs at full speed regardless of system hot water demands.

Annual system pumping cost may be reduced by installing a variable frequency drive (VFD) on the pump motor. Pump speed would be based upon system differential temperature.

The installation cost estimate assumes the pump motor is inverter duty, (which means that the motor would not also need to be replaced), and the VFD will be installed the pump motor. The system is already equipped with a two way valves. Installation costs and payback will be reduced by approximately 35% if a VFD is installed.

ECM #25: Upgrade Windows

A survey of the High School and DeMarest School revealed a mixture of types and sizes of

windows and functionality and condition varied throughout the building. The only a the gym

of the high school would require a replacement. DeMarest School will require all windows to

be replaced.

A window replacement project would result in an improvement in heat retention. In addition,

increased aesthetic value and occupant comfort would accompany a window project. It

should be noted however, that even an optimized window project can rarely be justified

solely on economic payback.

Because the economics alone are not sufficient to justify implementation, occupant comfort

and aesthetics should be the overriding considerations in deciding whether to move forward

with this project.

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

these economics should be refined with an investment grade analysis.

ECM #26: Creation of an Energy Awareness & Education Program

Hoboken 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.

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

Photovoltaic's (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 58


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.

Hoboken 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 Hoboken area is 4.6 meters per second. Ideal wind speeds for a successful project should

average over 6 meters per second.

For Hoboken , 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.

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 Hoboken Board of Education due to the lack of thermal requirements in the summertime.

Page 67


Retail Energy Purchasing: Recommendations

Electric

For the period studied, Hoboken School District was not utilizing a Third Party Supplier for the supply

of electricity.

Dome-Tech recommends the District establish a procurement strategy because there is an

opportunity to save money by switching to an electricity supplier versus paying the BGS default rate to

the utility. Typical savings are in the 10-15% range. This could represent an annual savings of

$50,000 for the District’s electric accounts.

Natural Gas

For the period studied, the Hoboken School District was utilizing Hess as a third party supplier for

natural gas with a floating rate. Further details about the existing contract were not available.

If the District is seeking budget certainty or would like to reduce their market exposure for Natural

Gas, Dome-Tech should be contacted for additional information regarding joining a purchasing co-

operative or developing a procurement strategy.

Utility Tariff and Rate Review: Electricity

Accounts and Rate Class: Hoboken School District has six facilities with nine electric

accounts with service behind Public Service Electric and Gas Company under rate classes

Large Power and Lighting Service-Secondary (LPLS), General Lighting and Power Service

(GLP) and Body Politic Lighting Service (BPL).

Electric Consumption and Cost: Based on the one-year period studied, the total annual

electric expenditure for the District is about $521,900 and the total annual consumption is

about 2,905,000 kilowatt-hours (kWh).

Average/Effective Rate per kWh: For the one year period studied, the BOE’s average

monthly cost per kilowatt-hour ranged from 16.00 ¢/kWh to 30.56 ¢/kWh, inclusive of utility

delivery charges. The District’s overall, average cost per kilowatt-hour during this period was

18.00 ¢/kWh.

o Note that these average electric rates are “all–inclusive”; that is, they include all supply service

(generation and commodity-related) charges, as well as all delivery service charges. The supply

service charges typically represent the majority (60-80%) of the total monthly bill. It is the supply

portion of your bill that is deregulated, which is discussed on subsequent slides in this section.

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.

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 (i.e., 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: Resources

Electric

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

seen customers with BGS-FP accounts save approximately 10-15% in projected energy costs by

switching to retail energy supplier. 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, 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.

Energy Purchasing Co-Operatives

o 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. 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.

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.

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.
