The potential annual energy cost savings and simple payback for the recommended ECMs is show below in Table 2. The overall savings, cost and payback for all ECM’s is shown in Table 3. The potential annual energy cost savings and simple payback for ECMs are shown in Section 5.0. Each individual measure’s annual savings are dependent on that measure alone, there are no interactive effects calculated. There are three options shown for Lighting ECM savings; only one option can be chosen. Incentives shown (if any) are based only on the SmartStart Incentive Program. Each measure recommended by CHA typically has a simple payback period of 15 years or less to be consistent with the requirements of the Energy Savings Improvement Plan (ESIP) which has a maximum payback period of 15 years. Occasionally, we will recommend an ECM that has a longer payback period, based on the need to replace that piece(s) of equipment, such as a boiler for example.

Heating Ventilation & Air Conditioning (HVAC) Systems Heating Systems: There are four (4) fuel oil fired boilers serving the Delaware Valley Regional High School building. Three Weil-McLain heating hot water boilers installed in 2007 is rated for 30 gallon/hr fuel oil input and a gross output of 3,480 MBH. One 1979 vintage H.B. Smith boiler is used as a backup heat source only. This boiler has a rated 30.1 gallon/hr oil input and 3,217.4 MBH output. It was noted that this boiler only runs a couple of times a year for testing. The heating hot water (HHW) loop is a primary-secondary loop configuration. Each boiler has its own primary inline pump. HHW is circulated to the building by two HHW pumps driven by 40 HP Marathon electric motors each equipped with Danfoss VFDs. The media center, a few of the classrooms, labs, gymnasiums, auditorium, kitchen and cafeteria are heated by using VAV boxes having HHW reheat coils supplied with air from either roof top units (RTUs) or air handling units (AHUs). The majority of the classrooms and offices are heated by HHW fin-tube radiation and unit hot water ventilators. HHW cabinet heaters are widely used in the hallways and HHW unit heaters are used in the mechanical room. Cooling Systems: Delaware Valley Regional High School building is provided with cooling from decentralized DX units including RTUs, AHUs and window units. Eleven York RTUs and one American Standard Inc RTU are used to cool labs, band room and some classrooms. AHU-1 manufactured by York is designated to cool the library. AHU-2 and 3 are used to cool the kitchen and cafeteria. The classrooms and offices that are not cooled by RTUs or AHUs are cooled by small window units.

Exhaust Systems: There are 80 exhaust fans of various sizes used to exhaust air from restrooms, storage areas, locker rooms, kitchen, conference rooms, woodshop and labs. However, the CFMs of these exhaust fans were unknown. These exhaust fans run 24/7.
Controls Systems The high school building has two (2) control systems: The boilers, RTUs and AHUs are currently controlled by an Auto-Matrix DDC system. The unit ventilators, fin-tube radiation and cabinet heaters are controlled by the old pneumatic control system. The Auto-Matrix DDC system was installed by Peterson Service Company. The DDC system resets the HHW temperature from 180 oF to 140 oF according to outdoor air temperature to reduce energy consumption of the boilers. The DDC system maintains the room temperature at 70 oF all the time regardless of the occupancy level. After discussion with facility staff, it was noted that night time setback program was not working properly. The AHUs and RTUs were shut down when the night time temperature was programmed which causes indoor temperature fluctuating too much at night. Therefore, nighttime temperature setback program was not used in the DDC system. Compressed air for the pneumatic system is provided by a single air compressor driven by two (2) 3 HP motors.
Domestic Hot Water Systems The building is served by one (1) oil fired Burnham domestic hot water heater. This heater has a rated 770 MBH energy input and 616 MBH energy output which results in a nameplate efficiency of 80%. The DHW is stored in an approximately 400 gallon storage tank. DHW is heated to 160 oF by the water heater and supplied to the storage tank to maintain the water temperature at 120 oF.
Kitchen Equipment The kitchen has a 2’x 10’ hood for exhausting deep fryers and grills. The kitchen has two electric deep fryers, one (1) electric Groen kettle, five (5) ovens and a dishwasher. The kitchen devices have energy star rating on them and are still in good shape. The kitchen also has two (2) 8’x6’ walk-in freezers and two (2) 8’x6’ walk-in refrigerators.
Plumbing Systems Delaware Valley Regional High School uses well water instead of city water. Some of the bathrooms plumbing fixtures were upgraded to low flow fixtures in the past few years after discussion with facility staff.
Lighting / Electrical Systems The high school building has a mixture of T-5, T-8 fluorescent lighting, compact fluorescent lights (CFL), halogen spot lights and some metal halides. The majority lighting fixtures in the building are T8 fluorescent fixtures. High intensity T-5s were observed in old gym and new gym. However, some low efficiency incandescent lights were observed to be used in auditorium and metal halides were used in the wrestling room. The majority of the lights are controlled by wall switches. The outdoor lights include incandescent lights, high pressure sodium lights, metal halides and a few mercury vapor lights. Most of the outdoor lights are currently controlled by timers. Some of the outdoor lights are controlled by photocell sensors. The rest of the lights are controlled by switches.

UTILITIES 3.0
Utilities in the high school building include electricity and fuel oil. Electricity is supplied and delivered by Jersey Central Power & Light. Fuel oil is currently delivered by Allied Oil LLC. Allied Oil LLC delivers 7,500 gallons #2 fuel oil each time and the fuel oil tank was filled nine times in the 2012-2013 heating season. The Transportation Building shares the same electric meter with the high school and uses propane supplied by Suburban Propane for heating. Delaware Valley Regional High School uses well water for the including the Transportation Building. The electricity usage of each building is calculated by the assumption that the electric usage is proportional to the square footage of the building. The electricity usage and fuel oil usage in 2012-2013 year for the buildings were as follows:

Under New Jersey’s energy deregulation law, the supply portion of the electric (or natural gas) bill is separated from the delivery portion. The supply portion is open to competition, and customers can shop around for the best price for their energy suppliers. The electric and natural gas distribution utilities will still deliver the gas/electric supplies through their wires and pipes – and respond to emergencies, should they arise – regardless of where those supplies are purchased. Purchasing the energy supplies from a company other than your electric or gas utility is purely an economic decision; it has no impact on the reliability or safety of the service. Additional information on selecting a third party energy supplier is available here: http://www.state.nj.us/bpu/commercial/shopping.html. See Appendix A for a list of third-party energy suppliers licensed by the Board of Public Utilities to sell within the building’s service area.

EPA PORTFOLIO MANAGER 4.0
The EPA Portfolio Manager benchmarking tool was used to assess the building’s energy performance. Portfolio Manager provides a site and source Energy Use Intensity (EUI), as well as an Energy Star performance rating for qualifying building types. The EUIs are provided in kBtu/ft2/year, and the performance rating represents how energy efficient a building is on a scale of 1 to 100, with 100 being the most efficient. In order for a building to receive and Energy Star label, the energy benchmark rating must be at least 75. As energy use decreases from implementation of the proposed measures, the Energy Star rating will increase. The site EUI is the amount of heat and electricity consumed by a building as reflected in utility bills. Site energy may be delivered to a facility in the form of primary energy, which is raw fuel burned to create heat or electricity, such as natural gas or oil; or as secondary energy, which is the product created from a raw fuel such as electricity or district steam. To provide an equitable comparison for different buildings with varying proportions of primary and secondary energy consumption, Portfolio Manager uses the convention of source EUIs. The source energy also accounts for losses incurred in production, storage, transmission, and delivery of energy to the site, which provide an equivalent measure for various types of buildings with differing energy sources. The results of the Portfolio Manager benchmarking tool are contained in the table below.

ENERGY CONSERVATION MEASURES 5.0
Energy conservation measures (ECM’s) are energy savings recommendations that typically require a financial investment. Energy savings can be in the form of:
electrical demand (KW=kilowatts),
electrical usage (KWh=Kilowatt-hour),
natural gas (Therms=100,000 BTU),
propane gas (Gallons=91,650 BTU),
#2Fuel Oil (Gallons =139,000 Btu), and
water (KGAL=1,000 gallons). These recommendations are influenced by the time period that it takes to “break even” referred to as “Simple Payback”. Simple payback is calculated by dividing the cost of implementing the ECM by the energy cost savings (in dollars) of that ECM. Another financial indicator of the performance of a particular ECM is the Return on Investment or ROI. Two other financial analyses included in this report are Internal Rate of Return (IRR) and Net Present Value (NPV). Internal Rate of Return is the discount rate at which the present value of a project costs equals the present value of the project savings. Net Present Value is the difference between present value of an investment’s future net cash flows and the initial investment. If the NPV equals “0”, the project would equate to investing the same amount of dollars at the desired rate. NPV is sometimes referred to as Net Present Worth. These values are provided in the summary in Appendix C.
5.1 Building Envelope The following are ECMs associated with Building Envelope.
5.1.1 ECM-1 Window Replacement This measure looks at replacing the old single pane windows in the cafeteria which are original to the building with double pane windows that have better seals and insulation. Replacement of these windows will result in a reduction of the buildings heating loads, therefore, resulting in natural gas savings. Energy savings of this measure were calculated by estimating the reduction in the heat transfer loss and the infiltration rate through the windows. The U value of the windows will be reduced from 0.60 Btuh/SF/oF to 0.40 Btuh/SF/oF and the infiltration factor is reduced from 0.20 CFM/LF to 0.10CFM/LF after upgrading the windows to double glazed windows with better seals. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

5.2 HVAC Systems The following are ECMs associated with the HVAC Systems
5.2.1 ECM-2 Install Demand Control Ventilation (DCV) for Media Center and Cafeteria
The Media Center (Library) has one (1) dedicated DX cooling air handling unit (AHU-1) with heating hot water heat, the Cafeteria also has one dedicated DX cooling air handing unit (AHU-2) with heating hot water heat. AHU-1 has a total of rated 7,700 CFM supply air including 3,900 CFM outdoor air which results in a 51% outdoor air. AHU-2 has a rated 11,100 CFM supply air including 6,000 CFM outdoor air which results in a 54% of outdoor air. The ventilation rate of these AHUs is very high. It is believed that these two (2) AHUs are designed to provide ventilation based on maximum occupancy. Maximum occupancy occurs infrequently and by reducing the amount of ventilation, energy savings will occur. Installation of carbon dioxide (CO2) sensors will allow for a reduction of outside air during periods of low occupancy. The quantity of ventilation air will be based on maintaining an acceptable CO2 level in the space as an indicator of indoor air quality. A limit of 1000 PPM of CO2 is recommended in ASHRAE Standard 62-2010, Ventilation for Acceptable Indoor Air Quality. Sensors will be installed to measure the building air CO2 concentration, and the control sequence of operation changed. During unoccupied periods, the outside air dampers should be closed. Bin weather data was utilized to obtain the annual operating hours required to maintain the current setpoint of 70°F. The BTU/Hr rating is calculated from the outdoor air (OA) conditions and air flow CFM (Cubic Feet per Minute). It is assumed that installing the controls will reduce the amount of OA to be conditioned by 20%. The annual thermal usage was estimated. The energy saving is the difference in natural gas usage for heating and electrical energy used for cooling. It should be noted that the percentage of the outdoor air in this calculation is based on the mechanical drawings. A more indepth energy study is recommended to calculate the energy savings based on the measured CFM of outdoor air and the fans running hours. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

5.2.2 ECM-3 Replace Motors with Premium Efficiency Motors
The HHW pump motors observed while onsite were not premium efficiency motors. It is suggested to replace them with premium efficiency motors. The total savings of this measure comes from motor efficiency improvement. Savings from replacing the motors with premium efficiency motors were calculated first by using the efficiency of each motor to get the actual electric demand drawn by the motor and then multiplying them with load percentage and run hours. Implementation of this measure will require installation of premium efficiency motors. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

5.2.1 ECM-TB1 Replace Propane Furnace and DX Unit in Office
The Propane furnace located in the 2nd floor office closet serves the office space in the Transportation Building. The propane furnace and DX unit are older and near the end of their useful life. It is recommended that the furnace and DX cooling system (coil and condensing units) be replaced through attrition with higher energy efficient equipment. This ECM assesses the replacement of the furnace and DX cooling system with equally sized, higher efficiency units. The total energy savings is the sum of propane savings and electric energy savings.

5.3 Control Systems The following are ECMs associated with the Controls Systems.
5.3.1 ECM-4 Repair the Existing DDC System to Utilize Nighttime Temperature Setback
The high school has an Auto-Matrix DDC control system to controls the RTUs, AHUs and HVs. The nighttime temperature setback feature is not working properly. In discussions with facility staff, it was stated that when the nighttime temperature setback was implemented the AHUs, RTUs and HVs would turn off rather than cycle and the indoor temperature could not be controlled in the desired range. It is suggested that School District contact the Auto-Matrix DDC service provider Person Service Company (PSC) to re-program the night temperature feature such that the units cycle to maintain a lower temperature during unoccupied times.

5.4 Domestic Hot Water System The following are ECMs associated with the Domestic Hot Water Systems.
5.4.1 ECM-5 Insulate DHW Piping Some domestic hot water (DHW) piping connecting the water heater and storage tank in the boiler room are currently not insulated. The heater supplies 160 oF hot water to the storage tank and the temperature of domestic hot water in the tank is reduced to 120 oF due to water mixing and heat loss. The surface temperature of these pipes is about 150 oF. Adding insulation to the domestic hot water pipes will reduce energy usage and improve efficiency of the steam boiler. The energy saving calculation for this measure quantifies the heat loss from DHW pipe surfaces. It is estimated that the uninsulated domestic hot water pipe surface
temperature is around 150 F. The difference between the heat loss before the insulation and after the insulation is the energy saving for this measure. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

5.5 Kitchen Equipment
5.5.1 ECM-6 Install Kitchen Hood Controller The kitchens in the High School contain exhaust hoods that are ventilated by exhaust fans located on the roof. The capacity and efficiency of the motors were not available at the time of the site visit so airflow capacity was estimated in the calculations. Currently, the kitchen hoods are controlled manually by kitchen staff which may result in the hood fans operating more than required to exhaust heat and smoke. Installing a Melink® hood control system is evaluated. Upon activation of the Melink® system, the hood lights will turn on and the fans reach a preset minimum speed of 10 and 50 percent. When cooking appliances are turned on, the fan speed will increase based on temperature sensed in the exhaust duct. During actual cooking, an optical sensor will sense particulates entering the hood and the speed will increase to 100 percent until smoke and heat are removed.

These units are controlled by to a dry bulb temperature and as a result run continuously throughout the year. Installing a CoolTrol® Cooler Control System was assessed. The system will monitor both dry and wetbulb temperature within the walk-in and allow evaporators and compressors to modulate up and down based on enthalpy set-points rather than by dry bulb temperature alone. Savings is a result of reduced run time of evaporator fans, compressors and door heaters. Implementation of the CoolTrol® Cooler Control System is turn-key from the company.

5.6 Plumbing Systems There are no ECMs associated with the Plumbing Systems.
5.7 Lighting/Electrical Systems The following are ECMs associated with the Lighting/Electrical Systems.
5.7.1 ECM-L1 Lighting Replacement / Upgrades It is proposed to replace the Wrestling Room metal halide fixtures with high output T-5 fixtures which have a longer life and consume much less energy. Also, the incandescent light fixtures in the Auditorium are proposed to be replaced by compact fluorescent lamps (CFL). These incandescent lights could also be replaced with LED lights, however, it was noted that the light output was straight down due to the depth of the lighting fixtures. It is suggested a in-depth study on these lights if LED would be considered to be used in the Auditorium. In addition, T-12 fluorescent lamp fixtures in the transportation building are proposed to be replaced by super T-8 lamp fixtures. Energy savings for this measure were calculated by comparing the existing and proposed fixture wattages and using estimated times of operation. These calculations are based upon 1 to 1 replacements with the fixtures. They do not take into account lumen output and square footage. A more comprehensive study may be performed to determine correct lighting levels. Supporting calculations, including assumptions for lighting hours and annual energy usage for each fixture, are provided in Appendix C. The implementation cost and savings related to this ECM are presented in Appendix C and summarized as follows:

5.7.2 ECM-L2 Install Lighting Controls (Occupancy Sensors) Currently, there are occupancy sensors located in the hallways of the school. However, it was observed that the lights in conference rooms, teachers’ lounge, lockers rooms, and bathrooms were sometimes left on even if the rooms were not occupied. Review of the comprehensive lighting survey determined that lighting in these areas could benefit from installation of occupancy sensors to turn off lights when the areas are unoccupied.
This measure recommends installing occupancy sensors for the current lighting system. Using a process similar to that utilized in Section 4.7.1, the energy savings for this measure was calculated by applying the known fixture wattages in the space to the estimated existing and proposed times of operation for each fixture.

5.7.3 ECM-L3 Lighting Replacements with Controls (Occupancy Sensors) This measure is a combination of ECM-L1 and ECM-L2; recommending replace/upgrade the current lighting fixtures to more efficient ones and installing occupancy sensors on the new lights. Interactive effects of the higher efficiency lights and occupancy sensors lead the energy and cost savings for this measure to not be cumulative or equivalent to the sum of replacing the lighting fixtures alone and installing occupancy sensors without the lighting upgrade.

PROJECT INCENTIVES 6.0
6.1 Incentives Overview The following sections give detailed information on available incentive programs including New Jersey Smart Start, Direct Install, New Jersey Pay for Performance (P4P) and Energy Savings Improvement Plan (ESIP). If the School District wishes to and is eligible to participate in the Energy Savings Improvement Plan (ESIP) program and/or the Pay for Performance Incentive Program (P4P), it cannot participate in either the Smart Start or Direct Install Programs. Refer to Appendix D for more information on the Smart Start program.
6.1.1 New Jersey Smart Start Program
For this energy audit, The New Jersey Smart Start Incentives are used in the energy savings calculations, where applicable. This program is intended for medium and large energy users and provides incentives for:
Electric Chillers
Gas Chillers
Gas Heating
Unitary HVAC
Ground Source Heat Pumps
Variable frequency Drives/Motors
Refrigeration
Prescriptive and Performance Lighting and Lighting Controls The equipment is procured using a typical bid-build method, installed and paid for and then the incentives are reimbursed to the school. Refer to Appendix D for more information on the Smart Start program.
6.1.2 Direct Install Program The Direct Install Program applies to smaller facilities that have a peak electrical demand of 200 kW or less in any of the previous 12 months. Buildings must be located in New Jersey and served by one of the state’s public, regulated electric utility companies. Direct Install is funded through New Jersey’s Clean Energy Program and is designed to provide capital for building energy upgrade projects to fast track implementation. The program will pay up to 70% of the costs for lighting, HVAC, motors, refrigeration, and other equipment upgrades with higher efficiency alternatives. If a building is eligible for this funding, the Direct Install Program can reduce the implementation cost of energy conservation projects. The Direct Install program has specific HVAC equipment and lighting requirements and are generally applicable only to smaller package HVAC units, small boilers and lighting retrofits.
The program pays a maximum amount of $75,000 per building, and up to $250,000 per customer per year. Installations must be completed by an approved Direct Install participating contractor, a list of which can be found on the New Jersey Clean Energy Website. Contractors will coordinate with the applicant to arrange installation of recommended measures identified in a previous energy assessment, such as this energy audit. The incentive is reimbursed to Delaware Valley Regional High School upon successful replacement and payment of the equipment. The following table summarizes the eligibility of each school for direct install. If a school does not qualify, it is because the electrical demand is greater than the maximum peak electrical demand of 200 kW for the last 12 month period.

Refer to Appendix D for more information on this program.
6.1.3 New Jersey Pay For Performance Program (P4P) The school will be eligible for incentives from the New Jersey Office of Clean Energy. The most significant incentives are available from the New Jersey Pay for Performance (P4P) Program. The P4P program is designed for qualified energy conservation projects applied to facilities whose demand in any of the preceding 12 months exceeds 100 kW. However, this average minimum has been waived for buildings owned by local governments or municipalities and non-profit organizations. Facilities that meet this criterion must also achieve a minimum performance target of 15% energy reduction by using the EPA Portfolio Manager benchmarking tool before and after implementation of the measure(s). If the participant is a municipal electric company customer, and a customer of a regulated gas New Jersey Utility, only gas measures will be eligible under the Program. Available incentives are as follows: Incentive #1: Energy Reduction Plan – This incentive is designed to offset the cost of services associated with the development of the Energy Reduction Plan (ERP).
Incentive Amount: $0.10/SF
Minimum Incentive: $5,000
Maximum Incentive: $50,000 or 50% of Facility Annual Energy Cost The standard incentive pays $0.10 per square foot, up to a maximum of $50,000, not to exceed 50% of facility annual energy cost, paid after approval of application. For building audits funded by the New Jersey Board of Public Utilities, which receive an initial 75% incentive toward performance of the energy audit, facilities are only eligible for an additional $0.05 per square foot, up to a maximum of $25,000, rather than the standard incentive noted above. Incentive #2: Installation of Recommended Measures – This incentive is based on projected energy savings as determined in Incentive #1 (Minimum 15% savings must be achieved), and is paid upon successful installation of recommended measures.
Electric
Base incentive based on 15% savings: $0.09/ per projected kWh saved.

For the purpose of demonstrating the eligibility of the ECM’s to meet the minimum savings requirement of 15% for the Pay for Performance Program, the recommended
ECM’s which have less than 15 years payback have been included in the incentive calculations. Refer to Appendix D for more information on this program.
6.1.4 Energy Savings Improvement Plan (ESIP) The Energy Savings Improvement Program (ESIP) allows government agencies to make energy related improvements to their facilities and pay for the costs using the value of energy savings that result from the improvements. Under the recently enacted Chapter 4 of the Laws of 2009 (the law), the ESIP provides all government agencies in New Jersey with a flexible tool to improve and reduce energy usage with minimal expenditure of new financial resources. ESIP allows local units to use “energy savings obligations” to pay for the capital costs of energy improvements to their facilities. This can be done over a maximum term of 15 years. Energy savings obligations are not considered “new general obligation debt” of a local unit and do not count against debt limits or require voter approval. They may be issued as refunding bonds or leases. Savings generated from the installation of energy conservation measures pay the principal of and interest on the bonds; for that reason, the debt service created by the ESOs is not paid from the debt service fund, but is paid from the general fund. For local governments interested in pursuing an ESIP, the first step is to perform an energy audit. Pursuing a Local Government Energy Audit through New Jersey's Clean Energy Program is a valuable first step to the ESIP approach. The “Local Finance Notice” outlines how local governments can develop and implement an ESIP for their facilities. The ESIP can be prepared internally if the entity has qualified staff. If not, the ESIP must be implemented by an independent contractor and not by the energy savings company producing the Energy Reduction Plan. The ESIP approach may not be appropriate for all energy conservation and energy efficiency improvements. Local units should carefully consider all alternatives to develop an approach that best meets their needs. Refer to Appendix D for more information on this program.
ALTERNATIVE ENERGY SCREENING EVALUATION 7.0
7.1 Solar
7.1.1 Photovoltaic Rooftop Solar Power Generation The schools were evaluated for the potential to install rooftop photovoltaic (PV) solar panels for power generation. Present technology incorporates the use of solar cell arrays that produce direct current (DC) electricity. This DC current is converted to alternating current (AC) with the use of an electrical device known as an inverter. The amount of available roof area determines how large of a solar array can be installed on any given roof. The table below summarizes the approximate roof area available on each school and the associated solar array size that can be installed.

The PVWATTS solar power generation model was utilized to calculate PV power generation; this model is provided in Appendix E. Installation of (PV) arrays in the state New Jersey will allow the owner to participate in the New Jersey solar renewable energy certificates program (SREC). This is a program that has been set up to allow entities with large amounts of environmentally unfriendly emissions to purchase credits from zero emission (PV) solar-producers. An alternative compliance penalty (ACP) is paid for by the high emission producers and is set each year on a declining scale of 3% per year. One SREC credit is equivalent to 1000 kilowatt hours of PV electrical production; these credits can be traded for period of 15 years from the date of installation. Payments that will be received by the PV producer (school) will change from year to year dependent upon supply and demand. There is no definitive way to calculate an exact price that will be received by the PV producer for SREC credits over the next 15 years. Renewable Energy Consultants estimates an average of $82/ SREC for 2012 and this number was utilized in the cash flow for this report. The system costs for PV installations were derived from recent solar contractor budgetary pricing in the state of New Jersey and include the total cost of the system installation (PV panels, inverters, wiring, ballast, controls). The cost of installation is currently about $4.00 per watt or $4,000 per kW of installed system, for a typical 100 kW system. There are other considerations that have not been included in this pricing, such as the condition of the roof and need for structural reinforcement. Photovoltaic systems can be ground mounted if the roof is not suitable, however, this installation requires a substantial amount of open property (not wooded) and underground wiring, which adds more cost. PV panels have an approximate 20 year life span; however, the inverter device that converts DC electricity to AC has a life span of 10 to 12 years and will most likely need to be replaced during the useful life of the PV system.
The implementation cost and savings related to this ECM are presented in Appendix E and summarized as follows:

Note: The installation of PV Solar arrays are only recommended for schools whose individual paybacks are less than 15 years. Before implementation is pursued, the school should hire a certified solar PV contractor.
7.1.2 Solar Thermal Hot Water Generation Active solar thermal systems use solar collectors to gather the sun’s energy to heat water, another fluid, or air. An absorber in the collector converts the sun’s energy into heat. The heat is then transferred by circulating water, antifreeze, or sometimes air to another location for immediate use or storage for later utilization. Applications for active solar thermal energy include providing hot water, heating swimming pools, space heating, and preheating air in residential and commercial buildings. A standard solar hot water system is typically composed of solar collectors, heat storage vessel, piping, circulators, and controls. Systems are typically integrated to work alongside a conventional heating system that provides heat when solar resources are not sufficient. The solar collectors are usually placed on the roof of the building, oriented south, and tilted around the site’s latitude, to maximize the amount of radiation collected on a yearly basis. Several options exist for using active solar thermal systems for space heating. The most common method involves using glazed collectors to heat a liquid held in a storage tank (similar to an active solar hot water system). The most practical system would transfer the heat from the panels to thermal storage tanks and transfer solar produced thermal energy to use for domestic hot water production. DHW is presently produced by gas-fired water heaters and, therefore, this measure would offer natural gas utility savings. Since these buildings are schools and classes are not held in the summer months, the effectiveness of the solar thermal hot water would not maximize and therefore this measure is not recommended.
7.2 Demand Response Curtailment Presently, electricity is delivered by Jersey Central Power & Light, which receives the electricity from regional power grid RFC East. PJM Interconnection is the regional transmission organization (RTO) that coordinates the movement of wholesale electricity in all or parts of 13 states and the District of Columbia including the State of New Jersey. Utility Curtailment is an agreement with the utility provider’s regional transmission organization and an approved Curtailment Service Provider (CSP) to shed electrical load by either turning major equipment off or energizing all or part of a facility utilizing an emergency generator; therefore, reducing the electrical demand on the utility grid. This program is to benefit the utility company during high demand periods and utility provider offers incentives to the CSP to participate in this program. Enrolling in the program will require program participants to drop electrical load or turn on emergency generators during high electrical demand conditions or during emergencies. Part of the program also will require that program participants reduce their required load or run emergency generators with notice to test the system. A pre-approved CSP will require a minimum of 100 kW of load reduction to participate in any curtailment program. From June 2012 through May 2013 the following table describes the electricity load profile for each building.
School Name

Onsite Generation
Eligible?
kW kW kW Y/N Y/N High School 525.9 371.8 438.0 N Y
Transportation Building 13.8 9.8 11.5 N N
Implementation for this measure will require a load shedding sequence to be established by using a demand control system. If the school has onsite electricity generation available, some load can be supplemented by running that device.

ECM Description SummaryIt is assumed the original system controls provide the full design ventilation outside air flow. Reducing outside air during occupied time periods will reduce heating and cooling energy used during the occupied period. A limit of 1000 PPM of CO2 is recommended in ASHRAE Standard 62-2007, Ventilation for Acceptable Indoor Air Quality. During unoccupied periods the outside air dampers should be closed.

ECM-5 Insulate DHW Pipes
Description Insulate heating system piping which are not currently insulated to reduce heat loss from piping and heat gain to the spaces.
Given Fuel Energy Cost = 3.37$ 6Operation (Hours/Week) = 168 Hours/WeekOperation (Heating Weeks/Year) = 52 Weeks/YearOperation (Hours/Year) = 8736 Hours/YearHeating Media = 1 Piping Material = 3Ambient Temperature = 75 oF
Formula Piping Correction Factor = (Current Transmission Coefficient / Reference Transmission Coefficient)Temperature Correction Factor = (Circulating Temperature - Ambient Temperature) / (Circulating Temperature - Reference Temperature)Hourly Heat Loss per pipe size and length = (Heat loss per foot [from chart]) x (Piping Correction Factor) x (Temperature Correction Factor) x (Pipe Length)Seasonal Heat Loss = (Hourly Heat Loss Total) x (Operating hours) / (Heating Efficiency) / (1,000 btu/Mbtu)
Energy Loss = (Seasonal Heat Loss) / (Conversion Factor [MBtu/Unit])Energy Loss Cost = (Energy Loss) x (cost/unit)

Simple Payback
ECM Description SummaryFor kitchens that contain walk-in coolers and freezers, CoolTrol is a controller that reduces energy consumption by controlling off of dewpoint temperature. Compressor cycling is reduced and the evaporator fans run 25% to 80% less. Door and frame heaters are also installed and controlled by store dew point temperature; this can reduce run time by up to 95% in coolers and 60% in freezers. The evaporator fan motors are also replaced with hi-efficiency fan motors saving 40% to 70% in energy. The proposed system comprises of an anti-sweat door controller, evaporator fan motor replacement and CoolTrol Cooler Control System.
