6 2.0 INTRODUCTION AND BACKGROUND New Jersey s Clean Energy Program, funded by the New Jersey Board of Public Utilities, supports energy efficiency and sustainability for Municipal and Local Government Energy Audits. Through the support of a utility trust fund, New Jersey is able to assist state and local authorities in reducing energy consumption while increasing comfort. The Riverton Public School is an elementary school located in Riverton, NJ, is a 42,240 square foot, three story masonry structure with exterior brick facing. The building was constructed in the 1910, with additions of a gymnasium in 1935 and a new classroom wing in There was a major renovation of the HVAC systems and lighting throughout the school in Occupancy includes approximately 282 students and 40 staff members. The school is open and occupied by maintenance personnel Monday through Friday from 7:00 am to approximately 11:00 pm during the school year. Students are typically in the school between 8:00 am and 3:15 pm. New Jersey BPU - Energy Audits

7 3.0 EXISTING CONDITIONS 3.1 Building - General Built in 1910 with several renovations and additions, the Riverton Public School building is a 42,240 square foot, three-story facility with a high bay area for the gym/auditorium. The school has approximately 282 students and 40 staff, and appeared fully utilized during the field survey. The building can be assumed to be fully occupied until 3:15 pm during the week. Custodial staff is typically in the building until 11:00 pm during the week. The hours of operation are: Monday through Friday 7:00 am to 11:00 pm (staff) Monday through Friday 8:00 am to 3:15 pm (students) The original building constructed in 1910 is a three story block building with a red brick exterior. The 1935 gym addition is a single story high bay block building with a red brick exterior also. The 1973 classroom addition is a single story block building with a red brick exterior. The 1910 portion of the school has a pitched roof above the attic space in the center surrounded by a built up asphalt roof. The 1935 and 1973 additions have built up asphalt roofs with 1 inch of rigid insulation installed in The staff had indicated the roofing systems on all three sections of the school were problematic and in need of replacement. The doors and windows in the school were replaced during the 2001 renovation with the exception of the gym windows. The gymnasium windows appear to be the original single pane, wooden frame units. The windows and doors were upgraded to double pane, steel frame units and appear to be in good condition. The insulation appears to be adequate in the school with the exception of the original 1910 attic area. The original insulation has deteriorated over time and has minimal R-value. New Jersey BPU - Energy Audits

8 3.2 Utility Usage Utilities include electricity, natural gas, and potable water. Electricity is delivered by PSE&G and supplied by SJEC. Natural gas is delivered by PSE&G and supplied by Hess. See Appendix A for a detailed utility analysis. The school has one electric meter and one gas meter. For the 12-month period ranging from July 2011 through June 2012, the utilities usage for the building was as follows: Actual Cost & Site Usage by Utility Electric Annual Usage 367,334 kwh/yr. Annual Cost 57,656 $ Blended Rate $/kwh Supply Rate $/kwh Demand Rate 6.91 $/kw Peak Demand 146 kw Min. Demand 87 kw Avg. Demand 107 kw Natural Gas Annual Usage 8,979 therms/yr. Annual Cost 10,002 $ Rate 1.11 $/Therm Annual Cost & Site Energy Usage Electrical usage was generally higher in the summer months when air conditioning equipment was operational. Natural gas consumption was highest in winter months for heating. The delivery component of the electric and natural gas bills will always be the responsibility of the utility that connects the facility to the power grid or gas line; however, the supply can be purchased from a third party; as is currently the case with electricity and natural gas. The electricity or natural gas commodity supply entity will require submission of one to three years of past energy bills. Contract terms can vary among suppliers. The charts below represent estimated utility end-use utility profiles for the building. The values used within the charts were estimated from a review of the utility analysis and the energy savings calculations. See appendix A for further end use information. New Jersey BPU - Energy Audits

9 Most of the electricity consumed by educational facilities is used to for lighting, cooling, and plug loads such as computers and copiers; most of the natural gas is used for space heating. Each school s energy profile is different, and the following charts represent typical utility profiles for K-12 schools. Typical End-Use Utility Profile for Educational Facilities 3.3 HVAC Systems The school has two different HVAC systems: one system for the original 1910 section and the 1935 gym and one for the 1973 addition. The 1910 original three story section and the 1935 gym addition are heated by two AERCO natural gas fired hot water condensing boilers and air conditioned by a McQuay split barrel air cooled chiller. The hot water from the boilers is circulated to the classrooms, gym and the administrative offices by two 10 hp Marathon Electric motors and pumps. These pumps do have associated variable frequency drives and only one pump needs to operate at a time. The chilled water is circulated by a supply and return pump configuration. There are two 10 hp Marathon Electric motors and pumps for the supply and there are two 3 hp Marathon Electric motors and pumps on the return lines. The chilled water pumps also have variable frequency drives. The conditioned water is supplied by a four pipe system to ceiling hung four pipe fan coils and the air is distributed through ceiling diffusers in each room. The 1973 addition has a Carrier HVAC roof top unit with DX cooling and natural gas forced air heating serving six classrooms and the library in the new wing. The Carrier system is a variable volume and temperature forced air system with twelve zones. This type of system has a separate thermostatically operated damper above the ceiling in each classroom which is controlled by the room thermostat. As the conditioned air is not needed and the zone dampers begin to close, the excess conditioned air is directed into a bypass relief damper located above the ceiling and recirculated back to the rooftop unit. New Jersey BPU - Energy Audits

10 The fresh air for the school is supplied by two energy recovery units located in the new 1973 addition and another in the 1910 section attic space. The energy recovery units can capture useful thermal energy from exhaust systems by use of desiccant wheels and transfer this recovered energy to incoming outside air thus reducing energy costs to condition the required outside air. The tempered air is then supplied to each classroom to satisfy outside air requirements. Specifics on the mechanical equipment can be found within the equipment inventory located in Appendix B Exhaust Systems The restrooms and warming kitchen are ventilated during the occupied times using roof mounted exhaust fans. Classrooms are ventilated by pre-heated fresh air that is provided by the two energy recovery units described above. The exhaust system fans are integrated into the school energy management systems (EMS) and generally operate during building occupancy. 3.4 Control Systems The Delta DDC system is located in the boiler room of the school has very limited capabilities. The system has very limited functioning energy management software programs installed and is mostly used to monitor the HVAC systems and room temperatures. The DDC system is restricted to start/stop programs based on outdoor air temperature for the Aerco boilers and McQuay chiller and does some degree of system monitoring. The Carrier HVAC roof top unit for the new classroom addition utilizes room temperature stats located in each classroom. This roof top unit is a stand-alone system and is not integrated in the Delta DDC system. The gym/auditorium has a remote Delta control panel for the operation of the two unit ventilators. The facility manager manually starts and stops the units based on occupancy. The temperature is monitored by wall mounted sensors that are connected back to the remote panel. The building is maintained at 72 to 74 degrees during the heating season and 68 to 72 degrees during the cooling season. The staff has the ability to adjust the set point +/- 2 degrees. 3.5 Lighting/Electrical Systems The interior lighting was upgraded to T-8 fixtures with electronic ballasts during the 2001 renovation. There are a few CFL and incandescent fixtures located in the gym/auditorium closets and storage areas. The gym/auditorium main lighting is 250 watt high bay metal halide fixtures with 250 metal halide wall pack fixtures over the bleacher area. Exterior lights consist of several 250 metal halide wall packs with some incandescent vestibule lighting. The majority of the exterior lighting is provided by utility owned street lamps. 3.6 Plumbing Systems Domestic Hot Water System New Jersey BPU - Energy Audits

11 The domestic hot water for the school is supplied by a Bradford White 80 gallon natural gas fired water heater.the hot water temperature is maintained at 120 degrees and the tank has a recovery rate of 190 gallons /hour. The water heater is located in the boiler room on the first floor and with the location of classrooms windows just above this area, the exhaust stack must be extended to the roof level which is approximately 50 feet. The excessive length of the exhaust stack could cause drafting issues and a heater malfunction. The water heater serves several student and faculty restrooms on the first floor and several smaller restrooms on the second floor. There is not a kitchen or shower facilities in this school Plumbing Fixtures The school s lavatories, water closets, and urinals have been replaced with low flow plumbing fixtures during the 2001 renovation. In general, lavatory faucets are 2.5 GPM with push type metering faucets, water closets are 1.6 GPF, and urinals are 1.0 GPF. New Jersey BPU - Energy Audits

12 4.0 ENERGY CONSERVATION MEASURES 4.1 ECM-1 Install A Condensing Gas Domestic Water Heater The existing 80 gallon natural gas water heater consumes energy by maintaining the water temperature at 120 degrees at all times even when not needed. Additionally, the water heater insulation is minimal, allowing for unnecessary heat transfer which contributes to inefficiency of the water heater the existing water heater could be replaced with a high efficiency natural gas on demand water heater. The on demand water heater uses technology to sense the flow of water and instantaneously heat the water to the desired temperature. The energy savings from this measure is the elimination of the 80 gallon tank of water being heated to 120 degrees even without demand for hot water. Water Heaters has an expected life of 12 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 6,267 therms and $6,956. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below ECM-1 Install a New Natural Gas Condensing DHW Heater Budgetary Annual Utility Savings Estimated Total Payback Payback Cost Maintenance Savings ROI Incentive * (without (with Electric Electric Nat Gas Total Savings incentive) incentive) $ kwh kw Therms $ $ $ $ Years Years 7, (0.1) * Incentive shown is per the New Jersey Smart Start Program. See section 5.0 for other incentive opportunities. This measure is recommended. 4.2 ECM-2 Incorporate The Existing Carrier Roof Top Unit Into the EMS System The Carrier roof top unit in the 1973 classroom addition is presently controlled by 24 volt room thermostats. These wall thermostats are set to a specific temperature and the areas are heated or cooled even during unoccupied periods such as nights and weekends. The Carrier HVAC unit could be integrated into the existing EMS system and scheduled to warm or cool the spaces when students and teachers are in the classrooms and adjust the temperatures accordingly after school hours to conserve energy. Electronic controls have an expected life of 25 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 91,834 kwh, 2,245 therms and $16,906. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: New Jersey BPU - Energy Audits

See section 5.0 for other incentive opportunities. This measure is recommended. 4.3 ECM-3 Upgrade the Attic Insulation-1910 Section The original constructed portion of the school has a pitched roof with a full attic. Loose fiberglass batt insulation has been installed of the conditioned spaces. Over the years, work on equipment and installation of network and other wiring has left much of this insulation misplaced or missing entirely. Installing 16 of insulation (R-38) above the ceiling of the conditioned spaces was assessed for this ECM. Addition of insulation will result in a reduced heating load, therefore saving natural gas usage. Attic insulation has an expected life of 35 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 61,652 therms and $68,434. The implementation cost and savings related to this ECM are presented in Appendix C and summarized as follows: ECM-3 Upgrade Attic Insulation-1910 Section Budgetary Annual Utility Savings Estimated Total Payback Payback Cost Maintenance Savings ROI Incentive * (without (with Electric Electric Nat Gas Total Savings incentive) incentive) $ kwh kw Therms $ $ $ $ Years Years 7, ,761 1, , * Incentive shown is per the New Jersey Smart Start Program. See section 5.0 for other incentive opportunities. This measure is recommended. 4.4 ECM-4 Lighting Replacement The building s classrooms and occupied spaces use linear fluorescent fixtures with T-8 bulbs; newer areas are equipped with T-8s and some T-5 bulbs. U-tube T-8s along with 2 foot T-8s are New Jersey BPU - Energy Audits

14 also used in some fixtures. Most can lights and surface mounted standard bulb fixtures use compact fluorescent lights (CFLs) to replace original incandescent bulbs. A comprehensive fixture survey was conducted of the entire building. Each switch and circuit was identified, and the number of fixtures, locations, and existing wattage established (Appendix C). Energy savings for this measure were calculated by applying the existing and proposed fixture wattages to estimated times of operation. The difference between energy requirements resulted in a total annual savings of 19,301 kwh with an electrical demand reduction of about13 kw. Supporting calculations, including assumptions for lighting hours and annual energy usage for each fixture, are provided in Appendix C. Lighting has an expected life of 15 years, according to the manufacturer, and total energy savings over the life of the project are estimated at 934,697 kwh, kw and $146,710. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM-4 Lighting Replacement / Upgrades Budgetary Annual Utility Savings Estimated Total Payback Payback Cost Maintenance Savings ROI Incentive * (without (with Electric Electric Nat Gas Total Savings incentive) incentive) $ kwh kw Therms $ $ $ $ Years Years 14,556 19, , , , * Incentive shown is per the New Jersey Smart Start Program. See section 5.0 for other incentive opportunities. This measure is not recommended in lieu of recommending ECM ECM-5 Install Occupancy Sensors The current elementary school lighting is controlled by manual switches. Lights are generally turned on in the morning and shut off at night. During occupied times, there are rooms that are not occupied; however, the lights remain on. Adding occupancy controls to the individual rooms will automatically control the lights based on occupancy. The occupancy sensor can be wall mounted near the switch or placed at the ceiling for larger room coverage. All occupancy sensors are equipped with a manual override feature. These sensors are generally not recommended in public toilet rooms. Lighting controls have an expected life of 15 years, according to the manufacturer, and total energy savings over the life of the project are estimated at 882,000 kwh and $106,400. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: New Jersey BPU - Energy Audits

16 5.0 PROJECT INCENTIVES 5.1 Incentives Overview New Jersey Pay For Performance Program The facility 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. This average minimum has been waived for buildings owned by local governments or municipalities and non-profit organizations, however. 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 each % over 15% add: $0.005 per projected kwh saved. Maximum incentive: $0.11/ kwh per projected kwh saved Gas Base incentive based on 15% savings: $0.90/ per projected Therm saved. For each % over 15% add: $0.05 per projected Therm saved. Maximum incentive: $1.25 per projected Therm saved Incentive cap: 25% of total project cost Incentive #3: Post-Construction Benchmarking Report This incentive is paid after acceptance of a report proving energy savings over one year utilizing the Environmental Protection Agency (EPA) Portfolio Manager benchmarking tool. Electric Base incentive based on 15% savings: $0.09/ per projected kwh saved. For each % over 15% add: $0.005 per projected kwh saved. Maximum incentive: $0.11/ kwh per projected kwh saved New Jersey BPU - Energy Audits

17 Gas Base incentive based on 15% savings: $0.90/ per projected Therm saved. For each % over 15% add: $0.05 per projected Therm saved. Maximum incentive: $1.25 per projected Therm saved Incentives #2 and #3 can be combined to yield additive savings. Total P4P incentives are summarized below: Incentives $ Elec Gas Total Incentive #1 $0 $0 $5,000 Incentive #2 $5,817 $3,567 $9,384 Incentive #3 $5,817 $3,567 $9,384 Total All Incentives $11,634 $7,135 $23,769 See Appendix D for calculations New Jersey Smart Start Program For this program, specific incentives for energy conservation measures are calculated on an individual basis utilizing the 2011 New Jersey Smart Start incentive program. This program provides incentives dependent upon mechanical and electrical equipment. If applicable, incentives from this program are reflected in the ECM summaries and attached appendices. If the complex qualifies and enters into the New Jersey Pay for Performance Program, all energy savings will be included in the total site energy reduction, and savings will be applied towards the Pay for Performance incentive. A project is not applicable for both New Jersey incentive programs Direct Install Program The Direct Install Program targets small and medium sized facilities where the peak electrical demand does not exceed 150 kw 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 or natural gas 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, natural gas, refrigeration, and other equipment upgrades with higher efficiency alternatives. If a building is eligible for this funding, the Direct Install Program can significantly reduce the implementation cost of energy conservation projects. The program pays 70% of each project cost up to $75,000 per electrical utility account; total funding for each year is capped at $250,000 per customer. Installations must be completed by a Direct Install participating contractor, a list of which can be found on the New Jersey Clean New Jersey BPU - Energy Audits

18 Energy Website at Contractors will coordinate with the applicant to arrange installation of recommended measures identified in a previous energy assessment, such as this document. The peak demand from the utility bills of kw, therefore this building is eligible for the Direct Install Program Energy Savings Improvement Plans (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 (see Appendix E). 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 New Jersey BPU - Energy Audits

19 6.0 ALTERNATIVE ENERGY SCREENING EVALUATION 6.1 Solar Photovoltaic Rooftop Solar Power Generation The facility was 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 building s roof has sufficient room to install a large solar cell array. All rooftop areas have been replaced, and are in good condition. It is recommended to install a permanent PV array at this time. The PVWATTS solar power generation model was utilized to calculate PV power generation. The closest city available in the model is Newark, New Jersey and a fixed tilt array type was utilized to calculate energy production. The PVWATT solar power generation model is provided in Appendix P. Federal tax credits are also available for renewable energy projects up to 30% of installation cost. Since the facility is a non-profit organization, federal taxes are paid and this project is eligible for this incentive. 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. 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. The average SREC value per credit is estimated to be about $80/ SREC per year based on current market data, and this number was utilized in the cash flow for this report. The existing load justifies the use of a 50 kw PV solar array. The system costs for PV installations were derived from contractor budgetary pricing in the state of New Jersey for estimates of total cost of system installation. It should be noted that the cost of installation is currently about $4.00 per watt or $4,000 per kw of installed system. Other cost considerations will also need to be considered. 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 need to be replaced multiple times 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 Budgetary Annual Utility Savings Estimated Total Payback Cost Maintenance Savings Federal Tax Credit (without incentive) Savings $ kw kwh therms $ $ $ $ Years $200, ,092 0 $9,277 0 $9,277 $ New Jersey BPU - Energy Audits

20 Solar Renewable Energy Certificate Program (SREC) for 2012 is $80/1000kwh This measure is not recommended due to the long payback time. It is suggested, however, that the market for SREC credits is closely monitored. This market is fluctuating, and if the value per SREC is increased the measure could potentially show for a shorter payback in the near future. 8.0 EPA PORTFOLIO MANAGER 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/ft 2 /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 ECMs, 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). Site EUI is a measure of a building s annual energy utilization per square foot. Site EUI is a good measure of a building s energy use and is utilized regularly for comparison of energy performance for similar building types. Site Energy Intensity = (Electric Usage in kbtu + Natural Gas in kbtu) Building Square Footage To provide an equitable comparison for different buildings with varying proportions of primary and secondary energy consumption, the Portfolio Manager uses the convention of Source EUIs. The source energy also accounts for all losses incurred in production, storage, transmission, and delivery of energy to the site; which provides an equivalent measure for various types of buildings with different energy sources. Source Energy Intensity = (Electric Usage in kbtu X Site/Source Ratio + Natural Gas in kbtu X Site/Source Ratio) Building Square Footage The EPA Score, Site EUI, and Source EUI for Riverton Public School are as follows: Energy Intensity Riverton Public School National Average EPA Score Site (kbtu/sf/year) Source (kbtu/sf/year) To be eligible to receive a national Energy Star score, a building must meet all three of these requirements: New Jersey BPU - Energy Audits

21 1. Building designation More than 50 percent of the building s gross floor area must be one of the spaces eligible to receive an Energy Star score. The remainder of the building must abide by specific rules for each space type. 2. Operating characteristics To ensure the building is consistent with the peer group used for comparison, each space in your building must meet certain minimum and maximum thresholds for key operating characteristics. 3. Energy data At least 12 full consecutive calendar months for all active meters, accounting for all energy use (regardless of fuel type) in the building. In addition, a Licensed Professional (meaning a Professional Engineer or Registered Architect) must verify that all energy use is accounted for accurately, that the building characteristics have been properly reported (including the square footage of the building), that the building is fully functional in accordance with industry standards, and that each of the indoor environment criteria has been met. The Riverton Public School is considered a higher than average energy consumer by the EPA Portfolio Manager which gives it a lower than average EPA score. For the School to qualify for the Energy Star label the EPA score is required to be above 75. There are several energy conservation measures recommended in this report, that if implemented will further reduce the energy use intensity and increase the EPA score of the Elementary School. This building does not appear to be eligible for Energy Star certification at this time.
