8 Middlesex Board of Education Hazelwood Elementary School II. FACILITY DESCRIPTION The Hazelwood Elementary School is located on Hazelwood Avenue in Borough of Middlesex, New Jersey. The 29,482 SF Elementary School was built in 1966 with mechanical upgrades in The building is a single story facility comprised of classrooms, multi-purpose room, library, mechanical room and offices. Occupancy Profile 7:00 am and 2:45 pm. The Elementary School s population consists of 217 students and 43 staff. Building Envelope Exterior walls for the Elementary School are typically 4 face brick, 8 concrete block, 2 ½ metal studs and 5/8 gypsum wall board. The windows throughout the Elementary School are original condition and appear to be maintained and in good condition. Typical windows are single pane, operable, ¼ clear glass with aluminum frames. Area above the windows in each classroom is glass block construction. Shades are utilized through the office and classroom areas of the facility for occupant comfort. The shades are valuable because they help to reduce heat loss in the winter and reduce solar heat in the summer. The roof is flat, sloped to roof drains, and is a grey color built up, ballasted type. The amount of insulation below the roof is unknown, but appears to be minimal. HVAC Systems The Elementary School heating systems consist of one (1) hot water boiler, unit ventilators and heating and ventilating (H&V) units. Cooling is provided by window air conditioners in the offices and several classrooms. Heating for the facility is provided by one HB Smith model HR-44 cast iron, gas-fired hot water boiler in the mechanical room. Heating hot water serves the hot water unit ventilators and H&V units throughout the school. The boiler is gas-fired, with an input of 2,255 MBH with an estimated efficiency of 75%. The boiler was installed in the late 1980s and is within it s useful service life as defined by ASHRAE. Hot water is circulated throughout the building s heating hot water loop via two base mounted, end suction pumps. The 1.5 HP, 1750 RPM pumps are located in the mechanical room, set up as one duty pump and one standby. The pump motors are standard efficiency motors. Exhaust System Air is exhausted from the toilet rooms through the roof exhausters. Classroom outside air is exhausted through roof mounted exhaust fans, centrally located over the corridors. Air passes from classrooms through concealed grilles in the top of wardrobe closets, then is ducted into the corridor ceiling plenum served by the exhaust fans. In most cases, classroom exhaust air grilles were blocked by casework or storage materials. This condition needs to be reviewed in more detail to assure adequate ventilation is provided to each room. HVAC System Controls 9C11064 June 15, 2012 FINAL Page 7 of 22

9 Middlesex Board of Education Hazelwood Elementary School The HVAC systems within the Elementary School are operated with the original pneumatic devices interfaced with a Honeywell DDC controller. Boiler HW temperature reset is provided via pneumatic transducers for DDC control of the existing HW mixing valve. Temperature control for classroom unit ventilators are via pneumatic 3-way valves connected to wall thermostats. There were no night setback or occupied/unoccupied mode capabilities observed in the system. Domestic Hot Water Domestic hot water for the school is provided by one (1) 200 MBH input AO Smith, 100 gallon storage gas fired commercial domestic hot water heater. Domestic hot water is distributed throughout the building via a piping loop with a pumped HW return circuit. The HW heater was installed in 2010, is in good working condition and is well within it s useful service life as defined by ASHRAE.

14 Middlesex Board of Education Hazelwood Elementary School ECM #1: Lighting Upgrade General Description: The majority of the interior lighting throughout the Hazelwood Elementary School is provided with fluorescent fixtures with older generation, 700 series 32W T8 lamps and electronic ballasts. Although 700 series T8 lamps are considered fairly efficient, further energy savings can be achieved by replacing the existing T8 lamps with new generation, 800 series 28W T8 lamps without compromising light output. CEG recommends, re-lamping all of the fixtures with 28W T8 lamps. In addition, the receiving area and a classroom area still have incandescent lamps. It is recommended to retrofit or replace all of the older fluorescent fixtures and the incandescent lights in these areas with newer fluorescent fixtures and compact fluorescent lamps. This ECM includes re-lamping of the existing fluorescent fixtures with 800 series, 28W T8 lamps. The ECM also includes retrofit of all older fluorescent fixtures with T8 or T5 fluorescent fixtures with electronic ballasts in the building. The new, energy efficient T8 fixtures will provide adequate lighting and will save on electrical costs due to better performance of the lamp and ballasts. The ECM also 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. 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. 9C11064 June 15, 2012 FINAL Page 13 of 22

16 Middlesex Board of Education Hazelwood Elementary School ECM #2: Lighting Upgrade Gymnasium Description: The gymnasium at Hazelwood Elementary School is currently lit via twenty-one 8 foot, 75W T- 12 fixtures with magnetic ballasts. The space would be better served with a more efficient, fluorescent lighting system. CE recommends upgrading the lighting to an energy-efficient T-8 system that includes new 28W T-8 4 lamp fixtures with new electronic ballasts. Additionally, attached to the gymnasium is a storage room which contains older 700 series T-8 fixtures which can be re-lamped into fixtures with 28W T8 lamps. This measure replaces all the 75W T-12fixtures with a well-designed T-8 lighting system. Twenty-one, 28 Watt T-8, 4 lamp fixtures will be required in order to meet the mandated 50 foot-candle average within the spaces. In addition, the replacement of four 700 series T-8 fixtures in the gym storage with new 28 Watt T-8 lamps will also be required in this ECM. Energy Savings Calculations: A detailed Investment Grade Lighting Audit can be found in Investment Grade Lighting Audit Appendix that outlines the proposed retrofits, costs, savings, and payback periods.

17 Middlesex Board of Education Hazelwood Elementary School ECM #3: Lighting Controls Upgrade Occupancy Sensors Description: Some of the lights in the Hazelwood Elementary School 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 (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 Media Centers. 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.

19 Middlesex Board of Education Hazelwood Elementary School ECM #4: Condensing Boiler Installation Description: The existing cast iron boiler is used as the primary source of heat for Hazelwood Elementary School. The existing boiler is approaching its life expectancy of a typical cast iron boiler and is close to being ready for a replacement. 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.
