East Orange School District Whitney Houston Academy Energy Audit II. FACILITY ENERGY USE INDEX (EUI) Energy Use Index (EUI) is a measure of a building s annual energy utilization per square foot of building. This calculation is completed by converting all utility usage consumed by a building for one year, to British Thermal Units (BTU) and dividing this number by the building square footage. EUI is a good measure of a building s energy use and is utilized regularly for comparison of energy performance for similar building types. Building Benchmarking data is collected and analyzed within the Commercial Building Energy Consumption Survey (CBECS), performed by the Energy and Information Administration (EIA). Building data is grouped by function types and tabulated, from which a median site and source energy intensity is determined. The national median or PEER Group Comparable in this instance is the middle value of the national population meaning half the buildings use more energy, and half use less. The PEER Group EUI allows us to compare the relative efficiency of the audited building to that of an average building with the same or similar primary function (i.e. group type). Source use differs from site usage when comparing a building s energy consumption with the national average. Site energy use is the energy consumed by the building at the building site only. Source energy use includes the site energy use as well as all of the losses to create and distribute the energy to the building. Source energy represents the total amount of raw fuel that is required to operate the building. It incorporates all transmission, delivery, and production losses, which allows for a complete assessment of energy efficiency in a building. The type of utility purchased has a substantial impact on the source energy use of a building. The EPA has determined that source energy is the most comparable unit for evaluation purposes and overall global impact. Both the site and source EUI ratings for the building are provided to understand and compare the differences in energy use. The site and source EUI for this facility is calculated as follows: Building Site EUI Electric Usage in kbtu Fuel Usage in kbtu Building Square Footage Building Source EUI Electric Usage in kbtu SS Ratio Fuel Usage in kbtu SS Ratio Building Square Footage Concord Engineering Group, Inc. 1C15143 August 31, 2015 FINAL Page 9 of 35

East Orange School District Whitney Houston Academy Energy Audit III. FACILITY DESCRIPTION The Whitney Houston Academy is located at 215 Dodd Street in East Orange, New Jersey. This 103,000 SF facility was originally built in 1910. The facility is a 3-story building with a basement level and two mezzanine levels. The school is comprised of classrooms, offices, an auditorium, a gym, a cafeteria, storage rooms, restrooms, and utility rooms. Occupancy Profile The school is in use 8:00 am till 3:00 pm, 5 days a week, with staff staying after hours for cleaning and some student activities. There are approximately 69 employees and 367 students which occupy the facility. Building Envelope Exterior walls for the building are masonry brick faced construction with drywall interior. The windows throughout the facility are in poor condition. Typical windows are single-pane operable with aluminum frames. The roof is a combination of A-Frame Style with wood trusses, wood sheathing, a vapor barrier, and tar shingles that comprises the main central structure; and then flat built up roofing on the gymnasium, auditorium, and east and west classroom wings. HVAC Systems The Houston Academy is primarily conditioned by a heating only central steam system, with limited air conditioning being provided by individual window air conditioning and thru-wall units. The steam heating plant consists of two Bethlehem Corporation Continental fire-tube boilers. The boilers are oil-fired rated at 60 gallons per hour of fuel input, or approximately 8,400 MBH. These boilers are 1977 vintage, and given their age are estimated to have an efficiency of 68%. Steam is produced by the boilers at 5 PSI. Fuel oil is stored in an approximately 2,000 gallon tank located outside. There is a large condensate receiving station located in the boiler room that had a significant leak, resulting in much of the return being dumped down the drain. We recommend repairing or replacing the receiving station if the boiler plant is to remain. The steam heating is distributed to radiators, cabinet heaters, unit ventilators and some baseboard throughout the classrooms, offices, hallways, gymnasium, cafeteria, and auditorium. The classrooms fitted with air conditioning have window units that range in capacity from ¾ to 1 ½ tons and range from 3 to 10 years of age. The main office and principals office has thru-wall packaged terminal heat pump units, which are primarily used for cooling. The units provide one ton of cooling with an efficiency of 9.3 EER.

East Orange School District Whitney Houston Academy Energy Audit ECM #3: Interior Lighting Controls Upgrade Description: Sometimes lights in a school are left on unnecessarily. In many cases the lights may be left on because of the inconvenience to manually switch lights off when a room is left or on when a room is first occupied. In some instances lights might be left on due to the misconception that it is better to keep the lights on rather than to continuously switch lights on and off. Although increased switching reduces lamp life, the energy savings outweigh the lamp replacement costs. The payback timeframe for when to turn the lights off is approximately two minutes. If the lights are expected to be off for at least a two minute interval, then it pays to shut them off. Lighting controls come in many forms. Sometimes an additional switch is adequate to provide reduced lighting levels when full light output is not needed. Occupancy sensors detect motion and will switch the lights on when the room is occupied. Occupancy sensors can either be mounted in place of a current wall switch, or on the ceiling to cover large areas. In addition, daylight control systems can be implemented using daylighting control systems that dim the electric lighting in response to interior daylight levels. The light output of the fluorescent lamps (T8) is varied by using electronic dimming ballasts. Photosensors, typically mounted in the ceiling, are used to measure the quantity of daylight in the space then determine the amount of dimming required to maintain adequate lighting levels in the total space. The U.S. Department of Energy sponsored a study to analyze energy savings achieved through various types of building system controls. The referenced savings is based on the Advanced Sensors and Controls for Building Applications: Market Assessment and Potential R&D Pathways, document posted for public use April 2005. The study has found that buildings have the potential to achieve significant energy savings through the use of building controls. The average energy savings are as follows based on the report: Occupancy Sensors for Lighting Control 20% - 28% energy savings. Savings resulting from the implementation of this ECM for energy management controls are estimated to be 20% of the total light energy controlled by occupancy sensors. This ECM includes installation of ceiling or switch-mount sensors for the teacher s lounge, offices, and restrooms. Sensors shall be manufactured by Sensorswitch, Watt Stopper or equivalent. The Investment Grade Lighting Audit Appendix of this report includes the summary of lighting controls which can be implemented in this ECM and outlines the proposed lighting/daylighting controls, costs, savings, and payback periods. The calculations adjust the lighting power usage by the applicable percent savings for each area that includes lighting controls.

East Orange School District Whitney Houston Academy Energy Audit ECM #4: STEAM TRAP REPLACEMENT PROGRAM Description: Steam traps are required for the proper operation of steam distributions systems. Traps are mechanical devices installed on steam pipes to remove condensate from steam flow. Unfortunately steam traps have a tendency to leak. On average 20% of steam traps are leaking in existing installations. Steam traps only have an average life of five (5) years. This ECM would replace approximately one hundred three (103) balanced pressure thermostatic steam traps. Where repairing is not feasible, the thermostatic traps will be replaced. Schedule 80 piping and extra heavy fittings will be used, and all piping and fittings between the unions will be replaced along with the steam traps. In addition, a complete steam trap survey will be performed along with tagging and implementing a 3-year, revolving, steam trap maintenance program.

East Orange School District Whitney Houston Academy Energy Audit ECM #5 Fuel Conversion to Natural Gas Description: The Whitney Houston Academy currently uses fuel oil to fire the boilers at the facility. Concord Engineering recommends converting to natural gas. While the conversion of existing equipment over to natural gas may not save energy, it will reduce energy costs. This ECM would replace the fuel oil used to fire the boilers with natural gas at Whitney Houston Academy. It is recommended new dual fuel burners being installed on the boiler to be primarily fired off natural gas. It is also recommended the district consult with the utility company to ensure adequate gas pressure is available at the site to support operation of the boilers. Since Concord Engineering also suggests upgrading to new natural gas boilers, only one of these measures should be implemented, as they conflict with each other. Concord recommends replacing the boilers in their entirety over converting the existing boilers at the facility to natural gas.

East Orange School District Whitney Houston Academy Energy Audit ECM #6: Boiler Replacement Description: The Whitney Houston School has two Bethlehem Corporation Continental fire-tube boilers. The boilers are oil-fired rated at 60 gallons per hour of fuel input, or approximately 8,400 MBH. These boilers are 1977 vintage, and given their age are estimated to have an efficiency of 68%. By converting the boilers to natural gas and installing new boilers substantial energy and cost savings could be realized. This ECM would install two Weil-McLain H Series gas/oil steam boiler rated at 8,660 MBH input to replace the two existing boilers. The owner should consult a professional engineer prior to installation of this measure to verify load requirements and consult with the utility regarding adequate gas pressure.

East Orange School District Whitney Houston Academy Energy Audit ECM #7: Plug Load Management Description: The Whitney Houston Academy has many types of plug in type equipment from computer monitors, copiers/printers, window air conditioning units, and other office equipment. As technology continues to advance and be integrated into society and the work environment, the devices in most instances require electrical power either a battery or power outlet. The increase in use of these devices is contributing vastly to the increase in electric usage at facilities and according to a study performed by the California Energy Commission can account for more than 20% of electricity use. In most instances these devices are left plugged in and sometimes on continuously whether occupants are present or not leading to a significant amount of wasted energy. By managing these loads with intelligent outlet receptacles facility and energy management staff can reduce the consumption of these devices and better control energy waste. The installation of a plug load management system with wireless controlled outlets will enable facility staff and energy managers to control the power draw of these systems during unoccupied periods. For cost estimating purposes a total of 50 outlets would be controlled by this system, further refinement of this number should be performed before installation. The basis of this measure is a Bert plug load management system with a network interface control system. Energy Savings Calculations: Data published by the DOE s Energy and Information Administration Commercial Buildings Consumption Survey states energy use breakouts for various types of buildings. This survey data was used to estimate the building energy consumption associated with Office Type Equipment. Savings are based on a ten (10%) percent reduction of the electric usage associated with interior equipment usage. Concord Engineering Group, Inc. 1C15143 August 31, 2015 FINAL Page 32 of 35

East Orange School District Whitney Houston Academy Energy Audit VI. ADDITIONAL RECOMMENDATIONS The following recommendations include no cost/low cost measures, Operation & Maintenance (O&M) items, and water conservation measures with attractive paybacks. These measures are not eligible for the Smart Start Buildings incentives from the office of Clean Energy but save energy none the less. A. Chemically clean the condenser and evaporator coils periodically to optimize efficiency. Poorly maintained heat transfer surfaces can reduce efficiency 5-10%. B. Maintain all weather stripping on windows and doors. C. Clean all light fixtures to maximize light output. D. Provide more frequent air filter changes to decrease overall system power usage and maintain better IAQ. E. Turn off computers when not in use. Ensure computers are not running in screen saver mode. F. Replace any old CRT Monitors with LED/LCD Type Monitors, which can draw as much as a quarter the power of an equivalent CRT monitor. G. Ensure outside air dampers are functioning properly and only open during occupied mode. H. Repair/Replace the large condensate receiving station if the boiler plant is to remain Concord Engineering Group, Inc. 1C15143 August 31, 2015 FINAL Page 35 of 35
