Russo, Ed.D., RSBA Delran Board of Education 52 Hartford Rd Delran, NJ Re: EXECUTIVE SUMMARY FOR DELRAN BOARD OF EDUCATION STATE OF NEW JERSEY LOCAL GOVERNMENT ENERGY AUDIT FINAL REPORT OUR PROJECT NUMBER D12257 Dear Mr. Russo: Dome-Tech was retained by the Delran 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 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 December 2011 December 2012, for the facilities included in this study, the District had an annual expenditure of: Electricity: approximately 4,347,307 kwh at a total cost of approximately $557,395 Natural Gas: approximately 183,760 therms at a total cost of approximately $197,010 The following buildings were evaluated under this study: Facility Name Total Floor Area Delran High School 138,441 Delran Middle School 98,123 Delran Intermediate School 64,444 Millbridge Elementary School 74,014 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

6 Mr. Christopher J. Russo, Ed.D., RSBA April 9, 2013 Delran Board of Education- D12257 Page 2 of 2 If all identified ECMs were to be implemented, they would provide the following estimated benefits to the Delran Schools: Total annual electrical savings: approximately 315,000 kilowatt-hours of electric consumption; 7.2% of baseline Total annual natural gas savings: approximately 9,200 therms of natural gas consumption; 5% of baseline Total annual cost savings: approximately $56,900 of utility cost; 7.5% of baseline Total annual CO 2 emissions reduction: 158 tons Total net estimated implementation cost: approximately $368,000 Total average simple payback: 6.5 years A summary of the projects that are recommended for implementation includes the following: Upgrading building controls (Demand Controlled Ventilation, Time of Day controls and changes to the Economizer Sequence of Operation), vending machine and personal computer plug load control, lighting upgrades, and installation of timers on domestic hot water heaters. Distributed/Renewable Energy Systems were also reviewed with the following conclusions: Dome-Tech considered three (3) different types of wind turbine technologies that consisted of both building-mounted and traditional ground-mounted variety. Ground-Mounted is not feasible for a majority of these sites due to space constraints and the surrounding buildings. The building-mounted wind turbine projects appear to be the only technically viable option. 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 547 kw dc at the Millbridge Elementary School Building to 761 kw dc at the Delran High School (2,032 kw dc total) could provide approximately 7% to 100% of each building s annual energy usage (48% of total energy usage for the entire district). Should the District decide to pursue a solar project, Dome-Tech recommends commissioning a more detailed study. CHP (Combined Heat and Power), Fuel Cells, and Micro-turbines were also considered and not recommended for any of the buildings due to a lack of significant year-round thermal loads. 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. Delran s school buildings scored between 31 and 90. See the report for further information. Regarding the procurement of utilities, Dome-Tech understands that the District s facilities in this study are served by five (5) electric accounts behind PSE&G and six (6) natural gas accounts behind PSE&G. All electricity and natural gas accounts are served by a third-party, retail energy 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, Karl F. Weissert, CEM, CEA, CBCP, LEED AP Manager of Performance Engineering Dome-Tech, Inc.

37 Energy Conservation Measures (ECMs) Notes and Assumptions The average CO 2 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 CO 2 per kwh generated. The EPA estimates that burning one therm of natural gas emits lbs CO 2. The EPA estimates that one car emits 11,560 lbs CO 2 per year. The EPA estimates that reducing CO 2 emissions by 7,333 lbs is equivalent to planting an acre of trees. The following utility prices provided were used within this study: School Electric $/kwh Natural Gas $/Therm High School $0.137 $0.977 Middle School $0.104 $1.949 Intermediate School $0.137 $0.969 Millbridge Elementary School $0.152 $0.813 Annual Electric Consumption (kwh) 4,347,307 n/a Annual Gas Consumption (Therms) n/a 183,760 Annual Electric Cost $557, n/a Annual Gas Cost n/a $197, Averaged Costs $0.128 $1.072 Delran BOE, NJ FINAL Energy Audit Report, April 2013

38 ECM #1: Demand Controlled Ventilation Delran Intermediate School Estimated Annual Savings: $14,904 Gross Estimated Implementation Cost: $3,696 NJ Smart Start Rebate: $0 Net Estimated Implementation Cost: $3,696 Simple Payback (years): 0.25 Annual Avoided CO 2 Emissions (tons): 61 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/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 CO 2 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 (gymnasiums and libraries). Because CO 2 levels correlate directly with the number of people in an occupied zone, CO 2 sensors will be used to control the 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.

The AHU supply air temperature was 95.6ºF. Due to the BMS programming, the outside air dampers opened 100% to help control the space temperature and bring it down to set point (70ºF). Dome-Tech recommends that this issue be evaluated and corrected by the school district s controls contractor and in house maintenance staff. The problem may be due to a defective pneumatic interface for the heating/cooling valve control or may exist with the heating valve/pneumatic actuator which will require repair or replacement of the valve/actuator.

The majority of all buildings utilize standard 32 Watt T-8 fluorescent lamps in classrooms and hallways. The 2011 building additions in the high school and middle school are equipped with dimmable 32 Watt T-8 fluorescent lamps with occupancy sensors. The hallways in the high school and middle school use occupancy sensors to turn off the lights when the areas become unoccupied after a period of time. These new addition areas and hallways are controlled by a Lutron lighting controls system that automatically turns the lights off at 11pm. Inefficient T12 fluorescent, halogen and incandescent lighting was found in some areas. Dome-Tech recommends replacing these lamps with efficiency fluorescent lighting. Many areas with variable occupancy were found to be equipped with occupancy sensors; however, Dome-Tech identified other areas that would benefit from the use of occupancy sensors such as teachers lounges, copy rooms and bathrooms. These upgraded light fixtures will reduce electrical consumption and cost while maintaining virtually the same lighting output.

However, the interior lighting operates continuously throughout building occupied hours (five days per week, from approximately 7 a.m. to p.m.). Installing an interior photocell will automatically measure the amount of outside light entering each space and turn off the lights when sufficient sunlight is present. Also, the photocells should be disabled during building unoccupied hours to ensure the lighting are not operating at night when the building is unoccupied. Further investigation is required to ensure that these controls can properly function with the Lutron controls.

50 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. Delran BOE, NJ FINAL Energy Audit Report, April 2013

51 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. NJ 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 Delran area is 5.8 meters per second at 50 meters above the surface of the earth. Ideal wind speeds for a successful project should average over 6 meters per second. For Delran BOE, 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).

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 at least 17.5 years. Average area wind speed is just below minimum requirements. 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 an average annual wind speed of 5.8 meters/sec, which is slightly below the minimum required wind speed of 6.0 meters/sec, Dome-Tech does not recommend installation of a wind turbine. The New Jersey State Clean Energy Program does not currently provide rebates for small wind system projects. Delran BOE, NJ FINAL Energy Audit Report, April 2013

53 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. This system application can be considered for potential placement on additional buildings or areas such as parking lots, in overhead mounting. Delran BOE, NJ FINAL Energy Audit Report, April 2013

56 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).

59 Utility Deregulation in New Jersey: Background and Retail Energy Purchasing Electric Accounts: 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. Originally, this threshold started at 1,500kW; now, it has come down to 750 kw. So, if an account s peak load contribution (as assigned by the utility) is less than 750 kw, then that facility/account is in the BGS-FP category. If you are unsure, you may contact Dome-tech for assistance. Delran BOE, NJ FINAL Energy Audit Report, April 2013

60 Utility Deregulation in New Jersey: Background and Retail Energy Purchasing (cont d) There are at least 3 important differentiating factors to note about each rate category: 1. The rate structure for BGS-FP accounts is different than the rate structure for BGS-CIEP accounts. 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. BGS-FP: Secondary (small to medium) Electric Accounts: 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, predominantly dependent upon whether a supplier can offer rates that are lower than the utility s (default) Price to Compare. BGS-CIEP: Primary (large) Electric Accounts: The BGS-CIEP category is quite different. These accounts pay an hourly market rate for energy when they do not switch to a retail provider. For BGS-CIEP accounts, 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 Delran BOE, NJ FINAL Energy Audit Report, April 2013

61 Utility Deregulation in New Jersey: Background and Retail Energy Purchasing (cont d) Natural Gas Accounts: The natural gas market in New Jersey is also deregulated. 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 monthly, 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 (The Henry Hub ) up to New Jersey (at the City Gate ) and ultimately to your facility. For additional information about natural gas trading and current market futures rates for various commodities, you can refer to 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. Delran BOE, NJ FINAL Energy Audit Report, April 2013
