II. FACILITY DESCRIPTION

The Oakview Elementary School is located at 350 DuBois Avenue in Woodbury, New Jersey. The 41,905 SF Oakview Elementary School was built in 1956. The building is a single-story structure and consists of office space for administrative use, all-purpose room, classrooms, kitchen and mechanical rooms.

Occupancy Profile

The typical hours of operation for Oakview Elementary School are Monday through Friday between 8:00 am and 4:30 pm, with custodial services running until 11:00 pm. The elementary school has a 12 month administrative occupancy of 56 people and 10 month occupancy with students of 320. Also, during the summer months summer recreation programs utilize available space to conduct their programs until approximately 4:30 pm.

Building Envelope

Exterior walls for the Oakview Elementary School are brick faced with a concrete block construction. The amount of insulation within the walls is unknown. The windows throughout the elementary school are in average condition. The roof is a flat, built up rubber roof that appears to be in good condition. The amount of insulation below the roof is unknown. Exterior doors had air gaps ranging in size of 1/16” to 1/8” in some areas and should be addressed with either re-aligning the doors or replacing the weather stripping entirely.

Heating Plant

Heating is provided to the facility from the Mechanical Room housing three natural gas fired, cast iron sectional hot water boilers made by Weil McLain. All three boilers have equivalent heating capacity characteristics having an input capacity of 1,527 MBH and output of 1,250 MBH for a combined output of 3,750 MBH. All three boilers appear to be well maintained and in good condition. Combustion tests were not available for review but based on age the assumption is the overall fuel-to-thermal efficiency for the boilers is approximately 75%, based on radiation losses and inefficiencies in operation inherent to the older technology. Both boilers are approximately 15 years old with a projected 20 years of their ASHRAE service life remaining. At this time, the boilers are not recommended for replacement. The heating hot water is circulated throughout the building via a constant speed end-suction pump set located in the Mechanical Room. The pumps are driven with standard efficiency motors that are recommended to be replaced with NEMA premium efficient motors. The hot water heating system provides heating hot water to the unit ventilators, hot water fin-tube radiators and heating and ventilation units throughout the facility.

Cooling Plant

Cooling is provided to the facility from an outdoor, air-cooled chiller as manufactured by Trane. The chiller has a cooling capacity equal to approximately 125 tons and is approximately 14 years old. Based on the chiller’s age, it has a projected six years remaining on its ASHRAE service life. The chiller appears to be well maintained and in good condition. At this time, the chiller is



not recommended for replacement. The chilled water is circulated throughout the building via a constant speed end-suction pump set located in the Mechanical Room. The pumps are driven with high efficiency motors. However a replacement is recommended in order to provide inverter-duty motors capable of operating via variable speed drive as recommended in another ECM included within this audit. The chilled water cooling system provides chilled water to the unit ventilators and any other air-handling systems with chilled water coils throughout the facility.

HVAC Systems

The Library is conditioned via a packaged air-to-air heat pump rooftop unit as manufactured by Trane. This unit provides approximately 7.5 cooling tons and 88 MBH of heating. The unit is relatively new, being installed in 2011 and is in great condition.

The All-Purpose Room is conditioned via indoor air-handling units that are of an older vintage but appear to be functioning. The units are not recommended for replacement based on energy savings alone at this time.

The classrooms within the facility are conditioned via unit ventilators with chilled water and hot water coils as manufactured by Nesbitt. The units appear to have been replacement units and are not recommended for upgrades at this time.

Exhaust System

Air is exhausted from the toilet rooms and other areas of the facility through the roof exhaust fans.

HVAC System Controls

The HVAC systems within the Oakview Elementary School are controlled by various electronic controls systems. There are Tracer Summit Controls, Siebe Environmental Controls and Barber Coleman controls. There is a modem installed in the control panel that provides supervisory control and monitoring to the Facilities Director.

Domestic Hot Water

The main source of domestic hot water for Oakview Elementary School is an AO Smith 250 MBH gas fired water heater with an integrated storage capacity of 100 gallons. The hot water heater is passed its ASHRAE service life of 12 years but appears to be in working condition. The hot water heater is recommended for replacement in the near future.

Lighting

Refer to the Investment Grade Lighting Audit Appendix for a detailed list of the lighting throughout the facility and estimated operating hours per space.

ECM #1: Lighting Upgrade – General Description: The majority of the interior lighting throughout Oakview Elementary School is provided with fluorescent fixtures with older generation, 700 series and 741/ECO 32W T8 lamps and electronic ballasts. Although these 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. Concord Engineering recommends that these fixtures remain unmodified due to the extensive costs which will be incurred if these fixtures are to be re-lamped and re-ballasted, which results in a long payback period. 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 burn-hours. 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.

ECM #1 - ENERGY SAVINGS SUMMARY



ECM #2: Lighting Upgrade – Gymnasium Description: The gymnasium at Oakview Elementary School is currently lit via 400 watt Metal Halide HID fixtures. The space would be better served with a more efficient, fluorescent lighting system. Concord Engineering recommends upgrading the lighting to an energy-efficient T5 high output system that includes new six lamp, 54 watt high output fixtures. This measure replaces all the HID, 400 watt HID MH fixtures with a well-designed T5 high output (HO) system. T5 High output fixtures with reflectors and wire guards will be required in order to meet the mandated 50 foot-candle average within the spaces. 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.

ECM #3: Lighting Controls Upgrade – Occupancy Sensors Description: Some of the lights in the Oakview 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 2005. 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. Energy Savings Calculations:

ECM #4: High Efficiency Gas Hot Water Heater

Description: The Oakview Elementary School has one A.O. Smith gas-fired hot water heater that serves the entirety of the original building. The gas fired heater has surpassed its life expectancy of a typical hot water heater. This ECM will replace the original gas fired domestic water heaters with Natural Gas fired 98.5% thermal efficient Bradford White eF Series. The unit will be replaced with a 199 MBH and 100 gallon heater. Energy Savings Calculations:

ECM #5: 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 and cold 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.

MOTOR REPLACEMENT SUMMARY



ECM # 6: Install VFD on Chilled Water Pumps Description: The chilled water system at the Oakview Elementary School utilizes two constant speed pumps to circulate chilled water from the air cooled chiller at the mechanical room throughout the building. Based on the survey of the existing equipment it appears that the chilled water air handlers have 3-way control valves for flow control. 3-way control valves allow constant flow of the water loop, requiring full pumping energy continuously, unlike 2-way control valves that provide flow through the heat exchanger equipment only when there is a call for cooling, and allow the system to reduce flow when it is not needed. This ECM includes the installation of Variable Frequency Drives on the two (2) 20 horsepower existing chilled water pumps. The VFD control is based on a differential pressure sensor in the water loop to measure demand for water. This ECM also includes replacement of the existing 3-way valves with 2-way valves which enable the system to operate correctly. Energy Savings Calculations:

ECM #7: Set Computers to Automatic Stand-by or Hibernate Modes Description: During the survey, it was noticed that the majority of the computers were left at ON position with the monitors at Screen Saver or OFF positions. Many personal computers (PC) came equipped with automatic Sleep Mode or Hibernate (power down) mode features. Normally computers boot up from Sleep Mode or Hibernate mode much faster than powering up from Shut Down position. Based on an independent study by the U.S. Department of Energy, Energy star® rated computers use approximately 70% less power during Sleep Mode. It is recommended to set up the PCs at this facility to switch into Sleep Mode after a short period of inactivity and Hibernate mode after a long period of inactivity. This ECM includes configuring the computers in the classrooms and the offices such that they automatically switch into:

- Sleep Mode after 15 minutes of inactivity - Hibernate after 60 minutes of inactivity

REM #1: 77.08 kW Solar System Description: The Oakview Elementary School has available roof and parking lot space that could accommodate a significant amount of solar generation. Based on the available areas a 77.08 kilowatt solar array could be installed, assuming the existing roof structure is capable of supporting an array. The array will produce approximately 91,296 kilowatt-hours annually that will reduce the overall electric usage of the facility by 4.7%. Energy Savings Calculations: See Renewable / Distributed Energy Measures Calculations Appendix for detailed financial summary and proposed solar layout areas. Financial results in table below are based on 100% financing of the system over a fifteen year period. Energy Savings Summary:

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.

F. Ensure outside air dampers are functioning properly and only open during occupied mode.
