Steven DiGeronimo Business Administrator / Board Secretary Pequannock Township Board of Education 538 Newark Pompton Pike Pompton Plains, New Jersey 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 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. Commissioning HVAC Performance Testing Energy Audits Project Management Retro-Commissioning Facility Management Consulting Energy Procurement Page 3

4 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 CO 2 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 buildingmounted 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 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 Building Performance - Delivered Page 4

21 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; 107 Cars removed from road; The Energy Information Administration (EIA) estimates that power plants in the state of New Jersey emit lbs CO2 per kwh generated. The Environmental Protection Agency (EPA) estimates that one car emits 11,560 lbs CO2 per year. -OR- -OR- 169 Acres of trees planted annually The EPA estimates that reducing CO2 emissions by 7,333 pounds is equivalent to planting an acre of trees. Page 21

22 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 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.

23 Energy Conservation Measure (ECM) #1: Install Destratification Fans in High Bays for Winter Use Middle School Hillview TOTAL Estimated Annual Savings: $13,960 $3,440 $17,400 Gross Estimated Implementation Cost: $2,900 $1,450 $4,350 NJ Rebate: $0 $0 $0 Net Estimated Implementation Cost: $2,900 $1,450 $4,350 Simple Payback (years): Annual Avoided CO 2 Emissions (tons): 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. Page 23

24 ECM #2: Install / Upgrade Pipe Insulation (on Pump Casings and Valves) High School Estimated Annual Savings: $120 Gross Estimated Implementation Cost: $70 NJ Rebate: $0 Net Estimated Implementation Cost: $70 Simple Payback (years): 0.6 Annual Avoided CO 2 Emissions (tons): 0 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. Estimated cost assumes that the insulation can be installed by in-house staff. Picture: Gerace uninsulated HHW valves Page 24

25 ECM #3: Vending Machine Power Management High School Middle School Hillview North Boulevard TOTAL Estimated Annual Savings: $1,910 $600 $200 $200 $2,910 Gross Estimated Implementation Cost: $1,790 $540 $350 $180 $2,860 NJ Rebate: $0 $0 $0 $0 $0 Net Estimated Implementation Cost: $1,790 $540 $350 $180 $2,860 Simple Payback (years): Annual Avoided CO 2 Emissions (tons): 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). Page 25

26 ECM #4: Replace Kitchen Equipment with Energy Star Rated Equipment High School Middle School TOTAL Estimated Annual Savings: $1,410 $2,910 $4,320 Gross Estimated Implementation Cost: $21,330 $24,000 $45,330 NJ Rebate: $0 $0 $0 Avoided Cost (Like and Kind Replacement): * $18,130 $20,400 $38,530 Net Estimated Implementation Cost: $3,200 $3,600 $6,800 Simple Payback (years): Annual Avoided CO 2 Emissions (tons): * Note: Avoided Cost = Cost of Like and Kind replacement Some of the kitchen equipment (reach-in refrigerators and food warmers) at the High School and the Middle School is older and less efficient than newer higher efficiency equipment. Replacing this equipment at the end of its service life with higher efficiency Energy Star labeled equipment will provide at least $4,000 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 efficient fan motors. Page 26

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%*. *Source: Turner, Wayne, Energy Management Handbook, Page 28

29 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 various configurations of one or more units. In most cases, the steam is converted to hot water before it is distributed to the end users. For the most part, these boilers are old and are nearing 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 approach the end of their service life, the efficiency degrades and the boiler must consume more fuel in order to produce the same rated output. In addition, there is a direct correlation between 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 load increases only those burners necessary to meet the load are fired. This allows each burner to run at optimal efficiency. Modular boilers operate under the same principal but for larger installations. In this case multiple boilers are used rather than multiple burners. Modular boilers usually are employed in 1000, 2000 or 3000 MBH sizes. 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 efficiencies can be realized. Picture: Old Steam Boiler (PMS) Page 29 Picture: Old HHW Boiler (Gerace)

30 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 economics alone at some of the facilities.

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). The result is excessive fresh air volumes which require costly (and unnecessary) conditioning. Demand-controlled ventilation controls the amount of outside air based upon the CO 2 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 CO 2 sensors and controlling the CO 2 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.

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. Page 35

40 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

41 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).

Wind Turbine Pros & Cons Pros Annual reduction in energy spend and use can be potentially reduced by almost $17,900 (13% reduction). Typical equipment life span is years. Reduction of annual greenhouse gas emissions by 39 tons per year. A wind turbine project could be incorporated into science and other curriculums to raise student awareness of energy alternatives. High visible green project. Cons Payback period is significant (over 8 years). Average area wind speed is not ideal and impacts performance. Prone to lighting strikes. Bird collisions are likely, but may be reduced with avian guard (building integrate only). Zoning may be an issue. Check with local zoning regulations. Wind turbines do create noise, although below 50 db (a typical car ride is over 80 db). 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 the District decide to pursue a wind turbine project, Dome-Tech recommends commissioning a more detailed study. Page 42

43 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. Page 43

49 Renewable Energy Technologies: Solar Photovoltaic 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 generations. Page 49

50 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.

51 Utility Tariff and Rate Review: Electricity Accounts and Rate Class: Pequannock Board of Education has five facilities with five electric accounts with service behind Jersey Central Power & Light Company under rate classes General Service Secondary 3 Phase. Electric Consumption and Cost: Based on the one-year period studied, the total annual electric expenditure for the District is about $342,000 and the total annual consumption is about 2,068,000 kilowatt-hours (kwh). Average/Effective Rate per kwh: For the one year period studied, the District s average monthly cost per kilowatt-hour ranged from /kwh to /kwh, inclusive of utility delivery charges. The District s overall, average cost per kilowatt-hour during this period was /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. Page 51

52 Utility Tariff and Rate Review: Natural Gas Accounts and Rate Class: Pequannock Board of Education has five facilities with five natural gas accounts behind Public Service Electric and Gas Company under rate classes Large Volume Gas (LVG). Natural Gas Consumption and Cost: Based on the one-year period studied, the total annual natural gas expenditure for the District is about $402,000 and the total annual consumption is about 292,000 therms (th). Natural gas is used predominantly throughout the winter period for heating purposes. Average/Effective Rate per Therm: For the one year period studied, the District s average cost per therm ranged from $0.90 to $4.55 per therm, inclusive of utility delivery charges. The District s overall, average cost per therm during this period was $1.51 per therm. o Note that these average natural gas rates are all inclusive ; that is, they include all supply service (interstate transportation and commodity-related) charges, as well as all delivery service charges.

53 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

54 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 happenswhen 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 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 1 st. 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 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 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 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. For more information concerning hourly electric market prices for our region, please refer to Page 54

55 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 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. Page 55

56 Retail Energy Purchasing: Recommendations and Resources Electric o 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 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. 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. Page 56
