The 31,617 GSF Public School building was built in 1922 with additions/renovations in 1927, 1955, and The building is a partial two-story facility (basement plus 1 st and 2 nd floors) comprised of classrooms, library, art room, computer room, science rooms, prekindergarten and kindergarten classrooms, nurse s office, teacher work room, faculty room, administrative offices, boiler room, electrical rooms, and a multi-purpose room with a kitchen. Occupancy Profile The typical hours of operation for the Ethel M. Burke Elementary School are Monday through Friday between 8:00 am and 2:30 pm. Building Envelope The original 1922 and 1927 sections of the building are built of 8 CMU and 4 brick with concrete beams. The windows throughout the facility are in poor condition and were installed in Typical windows throughout the facility are double pane, operable, ¼ clear glass with aluminum frames with insulated panels. This year, the School District will be replacing the window systems with 7/8 insulated, low-e units. Blinds are utilized throughout the facility for occupant comfort. The blinds are valuable because they help to reduce heat loss in the winter and reduce solar heat in the summer. The 1994 multi-purpose/kitchen addition is built of 4 split-face blocks, 8 concrete blocks, steel frame, and 2 rigid insulation on a roof deck with a roof membrane. The roof over the older sections of the building is comprised of a built-up roof over T&G wood sheathing with insulated ceiling tile. HVAC Systems The HVAC system consists of hot water boilers, packaged rooftop cooling units, classroom unit ventilators, a split system in the nurse s office, a vertical self-contained unit in one classroom, and window air conditioners in several rooms along with the administration office. The hot water is conveyed to the hot water coils via two (2) 5 HP secondary pumps manufactured by Aurora. The hot water is circulated thru the hot water boilers by two (2) 1/2 HP primary pumps also manufactured by Aurora. The boilers are 1998 vintage Lochinvar Power-Fin, modular, gas-fired hot water boilers with a rated input of 1,000 MBH each and an output of 880 MBH. These boilers serve the hot water coils within the unit ventilators and hot water cabinet heaters at the entrances. The multi-purpose room is heated/cooled by two (2) Carrier packaged rooftop units rated at 15-Tons of DX cooling and 270 MBH of gas-fired heating. The nurse s office has a one-ton Airedale split ceiling cassette unit with the condenser mounted on the roof. Also, there is a 3-Ton Airedale vertical self-contained unit in one of the classrooms.

15 ECM #1: Lighting Upgrade Description: The majority of the interior lighting throughout the Ethel M. Burke Elementary School building is provided with fluorescent fixtures with older generation, 700 series 32W T8 lamps and electronic ballasts. These fixtures were surveyed to find that a replacement lamp could not be retrofitted without the replacement of the existing electronic ballast. The cost to replace the electronic ballast makes it cost prohibitive for the savings from 32W lamps to 28W lamps therefore these fixtures were not included in the calculation. In some areas, incandescent lights were found which could be replaced with new compact fluorescent lamps. The ECM includes replacement of any incandescent lamps with compact fluorescent lamps. Compact fluorescent lamps (CFL s) were designed to be direct replacements for the standard incandescent lamps which are common to table lamps, spot lights, hi-hats, bathroom vanity lighting, etc. The light output of the CFL has been designed to resemble the incandescent lamp. The color rendering index (CRI) of the CFL is much higher than standard fluorescent lighting, and therefore provides a much truer light. The CFL is available in a myriad of shapes and sizes depending on the specific application. Typical replacements are: a 13-Watt CFL for a 60-Watt incandescent lamp, an 18-Watt CFL for a 75-Watt incandescent lamp, and a 26-Watt CFL for a 100-Watt incandescent lamp. The CFL is also available for a number of brightness colors that is indicated by the Kelvin rating. A 2700K CFL is the warmest color available and is closest in color to the incandescent lamp. CFL s are also available in 3000K, 3500K, and 4100K. The 4100K would be the brightest or coolest output. A CFL can be chosen to screw right into your existing fixtures, or hardwired into your existing fixtures. Where the existing fixture is controlled by a dimmer switch, the CFL bulb must be compatible with a dimmer switch. In some locations the bulb replacement will need to be tested to make sure the larger base of the CFL will fit into the existing fixture. The energy usage of an incandescent compared to a compact fluorescent approximately 3 to 4 times greater. In addition to the energy savings, compact fluorescent fixtures burn-hours are 8 to 15 times longer than incandescent fixtures ranging from 6,000 to 15,000 burn-hours compared to incandescent fixtures ranging from 750 to 1000 burnhours. However, the maintenance savings due to reduced lamp replacement is offset by the higher cost of the CFL s compared to the incandescent lamps. The exit signs in the facility were converted from incandescent to compact fluorescents during the T8 lighting upgrade of the facility. Only the internal components of the fixtures were retrofitted. This application would be an excellent opportunity for LED technology. LED is an acronym for light-emitting-diode. LED s are small light sources that are readily associated with electronic equipment. LED exit signs have been manufactured in a variety of shapes and sizes. There are also retrofit kits that allow for simply modification of existing exit signs to accommodate LED technology. The benefits of LED technology are substantial. LED exit signs will last for years without maintenance. This results in tremendous maintenance savings considering that incandescent or fluorescent lamps need to be replaced at a rate of 1-5 times per year. Lamp costs ($2-$7 each) and labor costs ($4-$10 per lamp) add up rapidly. Additionally, LED exit lights only uses 4 Watts. In comparison, conventional exit signs use Watts. This ECM replaces all exit signs with compact fluorescent lamps in their entirety with new exit signs June 22, 2011 FINAL Page 13 of 35

16 containing LED technology. It is recommended that samples of the products be installed to confirm that they are compatible with the existing electrical system. Energy Savings Calculations: The Investment Grade Lighting Audit Appendix outlines the hours of operation, proposed retrofits, costs, savings, and payback periods for each set of fixtures in the each building. Rebates and Incentives: There are incentives available from NJ Smart Start Program for a portion of the retrofits in this ECM. Incentives are calculated as follows: From the Smart Start Incentive appendix, the retrofit of an incandescent with a compact fluorescent fixture warrants the following incentive: $25 per 1 lamp fixture $30 per 2 lamp fixture SmartStart Incentive = # of 1 Lamp Fixtures $25 = 22 $25 = $550 From the Smart Start Incentive appendix, the retrofit of a compact fluorescent exit sign with a LED exit sign warrants the following incentive: $10 per LED Exit sign ( 75kW facility connected load) $20 per LED Exit sign ( 75kW facility connected load) SmartStart Incentive = # of Exit Signs $10 = 9 $10 = $90 Replacement and Maintenance Savings: There are no Replacement and Maintenance Savings for compact fluorescent light fixtures. LED Exit Signs Maintenance savings = 9 fixtures x 2 bulbs/fixture x ($3/bulb + $4/bulb installation) = $126/yr June 22, 2011 FINAL Page 14 of 35

18 ECM #2: Lighting Upgrade Multi-Purpose Room Description: The all-purpose room at Ethel M. Burke Elementary School utilizes 250W low bay probe start metal halide fixtures for its lighting. Utilizing pulse start metal halide lamps in low and high bay spaces is a superior option over probe start metal halide fixtures. This ECM includes replacement of each of the existing multi-purpose room probe start metal halide ballast and lamp with pulse start metal halide ballast and lamp retrofit kits. The retrofit for the probe start metal halide fixtures includes a one for one fixture replacement. The lamp selected will provide equivalent light compared to the average light output of the existing probe start metal halide fixtures. The bulb replacement cost for the pulse start metal halide lamps compared to the existing probe start metal halide lamps were found to be approximately equal and therefore not included in the savings calculations. Hours of Operation Multi-Purpose Room: 2,600 Hours/Yr Energy Savings Calculations: The Investment Grade Lighting Audit Appendix outlines the proposed retrofits, costs, savings, and payback periods. NJ Smart Start Program Incentives are calculated as follows: From the Smart Start Incentive Appendix, the following incentives are warranted: Pulse Start metal Halide fixtures (for fixtures 150 watts) = $25 per Fixture Smart Start Incentive = (# of Fixtures Replaced $25) Smart Start Incentive = (18 $25) = $450 There is no significant replacement or maintenance savings generated with this ECM.

20 ECM #3: Lighting Controls Upgrade Occupancy Sensors Description: Some of the lights in the school building are left on unnecessarily. In many cases the lights are left on because of the inconvenience to manually switch lights off when a room is left or on when a room is first occupied. This is common in rooms that are occupied for only short periods and only a few times per day. In some instances lights are 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. 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 The study has found that commercial 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 and daylight sensors (The majority of the savings is expected to be after school hours when rooms are left with lights on) This ECM includes installation of ceiling or switch mount sensors for individual offices, classrooms, large bathrooms, and libraries. 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 implemented in this ECM and outlines the proposed 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.

22 ECM #4: Condensing Domestic Hot Water Heater Description: The original source for domestic hot water for the kitchen is provided by one 75 gallon dedicated water heater made by Bradford White. The efficiency of the gas hot water heaters is approximately 80%. Newer technology available for this type of equipment would provide more efficient operation. Condensing hot water heaters provide substantially improved efficiency over standard hot water heaters (up to 97% thermal efficiency.) The thermal efficiency gain is a result of condensing the flue gases allowing for maximum extraction of heat from the combustion process. This ECM includes installation of new central tank type condensing hot water heater to replace the existing standard efficiency hot water heater. The efficiency of the proposed hot water heater represents an increase of 20% for all hot water use in the building. The basis for this ECM is the AO Smith condensing hot water heater model number BTH 120 to replace the existing water heaters. Energy Savings Calculations: Non-Heating Gas Consumption: 46 Therms/month (Based on average June through September Utility Bills) 46 Therms/month x 12 months = 552 Therms Estimated Existing HWH Gas Consumption (100%): 552 Therms X 100% = 552 Therms Dom.

25 ECM #5: Air Conditioning Unit Upgrades Description: The all-purpose room at Ethel M. Burke Elementary School is air conditioned by packaged rooftop AC units. The units currently installed are inefficient compared to modern equipment and can be replaced with new high efficiency units. New air conditioners provide higher full load and part load efficiencies due to advances in inverter motor technologies, heat exchangers and refrigerants. This ECM includes one-for-one replacement of the older air conditioning units with new higher efficiency systems. It is recommended to fully evaluate the capacity needed for all new systems prior to moving forward with this ECM. A summary of the unit replacements for this ECM can be found in the table below: ECM INPUTS SERVICE / LOCATION RTU-1A Multi-Purpose Room 1 180, Carrier 48PM RTU-1B Multi-Purpose Room 1 180, Carrier 48PM Total 2 360, The manufacturer used as the basis for design is Carrier. This ECM includes replacement of the unit in its entirety. All units are one for one style replacements with matching capacity of the new units to the old units. Operating efficiency of the existing equipment is estimated due to lack of data from the existing units.

28 ECM #6: Heating HW Condensing Boiler Installation Description: The existing Lochinvar boilers are used as the primary source of heat for the building. The existing boilers are over 18 years old and within the typical life expectancy of a cast iron boiler, which is 25 years. The equipment appears to be maintained in fair operating condition. It is difficult to predict the point at which the boiler becomes inoperable. With the increased efficiency of the condensing boilers, the savings can be substantial. New condensing boilers could substantially improve the operating efficiency of the heating system of the building. Condensing boiler s peak efficiency tops out at 99% depending on return water temperature. Due to the operating conditions of the building, the annual average operating efficiency of the proposed condensing boiler is expected to be 88%. The existing boiler s efficiency is approximately 75%, which makes the condensing boilers an 13% increase in efficiency. This ECM is based on variable supply water temperature adjusted based on outdoor temperature. This ECM includes installation of two condensing gas fired boilers to replace the existing two boilers. The remaining Patterson-Kelley boiler would remain as a back-up. The basis for this ECM is Aerco model number KC1000. The boiler installation is based on a one for one replacement based on capacity of the existing boiler.

31 ECM #7: Install NEMA Premium Efficiency Motors Description: The improved efficiency of the NEMA Premium efficient motors is primarily due to better designs with use of better materials to reduce losses. Surprisingly, the electricity used to power a motor represents 95 % of its total lifetime operating cost. Because many motors operate continuously 24 hours a day, even small increases in efficiency can yield substantial energy and dollar savings. The electric motors driving the hot water pumps are candidates for replacing with premium efficiency motors. These standard efficiency motors run considerable amount of time over a year. This energy conservation measure replaces existing inefficient electric motors with NEMA Premium efficiency motors. NEMA Premium is the most efficient motor designation in the marketplace today.

34 ECM #8: Programmable Thermostats for Central A/C System Description: The air conditioning for the Multi-Purpose Room is provided by direct expansion cooling. The system is controlled with a mechanical thermostat. Currently, there is no night setback for this system. Energy consumption of the air conditioning system can be reduced by installing a programmable thermostat. Programmable thermostats for air conditioning units are available to utilize time-ofday schedules for occupied and unoccupied times and set-backs. This energy conservation measure will install programmable thermostats to control the central air conditioning systems. The recommended thermostat set points for air conditioning in the facility are as follows: Occupied Cooling = Unoccupied Cooling = 74 F 78 F Energy Savings Calculations: Energy savings calculations are derived from the annual energy consumption of the unit based on total cooling capacity and seasonal integrated energy efficiency of the system. The calculation uses the number of annual cooling degree days (CDDs) and the estimated hours of setback during the unoccupied period on each day. First total energy consumption of the unit in occupied and unoccupied modes are calculated using the total cooling capacity and the CDDs. Energy Consp., kwh (Occupied) = BTU Cooling Capacity, Hr Operation Hours (CDDs 65 F) IEER 1000 W kwh Energy Consp., kwh (Unoccupied) = BTU Cooling Capacity, Hr Operation Hours (CDDs 70 F) IEER 1000 W kwh Total Annual Energy Consumption of the unit in partly occupied and unoccupied settings are calculated simply by proportioning the hours of day in occupied mode and unoccupied modes using equation below: June 22, 2011 FINAL Page 32 of 35

37 V. 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 which saves the monitor screen not energy. F. Ensure outside air dampers are functioning properly and only open during occupied mode.
