3 I. HISTORIC ENERGY CONSUMPTION/COST The energy usage for the facility has been tabulated and plotted in graph form as depicted within this section. Each energy source has been identified and monthly consumption and cost noted per the information provided by the Owner. Electric Utility Provider: Electric Utility Rate Structure: Third Party Supplier: Natural Gas Utility Provider: Utility Rate Structure: Third Party Supplier: Water Utility Provider: Utility Rate Structure: Sewer Service Suppler: Jersey Central Power & Light (JCP&L) General Service 3-Phase Direct (Hess) New Jersey Natural Gas (NJNG) General Service Large Direct (Hess) United Water WTM (Metered Service) Municipal Utilities Authority Fixed Payment The electric usage profile represents the actual electrical usage for the facility. The electric utility measures consumption in kilowatt-hours (KWH) and maximum demand in kilowatts (KW). One KWH usage is equivalent to 1000 watts running for one hour. One KW of electric demand is equivalent to 1000 watts running at any given time. The basic usage charges are shown as generation service and delivery charges along with several non-utility generation charges. Rates used in this report reflect the historical data received for the facility. The district installed an onsite solar array to generate power, reducing the amount of electric it purchases from the utility. New Jersey s net metering guidelines allow them to get an on bill credit for exported KWH, to be utilized in the months to follow, up until the annual balance date when any remaining credit of KWH is paid to the owner based on average electric market pricing for the year. The Electric Billing Data summarized reflects the net electric used by the facility based on utility purchased electric and onsite solar. Note the price for electric is only based on grid purchased power, as any reductions in energy use will reduce utility purchased power requirements. The gas usage profile within each facility report shows the actual natural gas energy usage for the facility. The gas utility measures consumption in cubic feet x 100 (CCF), and converts the quantity into Therms of energy. One Therm is equivalent to 100,000 BTUs of energy. The water usage profile for this facility shows the actual water consumption based on collected utility bills. The water utility measures consumption in gallons (gal), and converts the quantity into 1,000 gallons. September 29, 2014 FINAL Page 2 of 63

10 II. FACILITY DESCRIPTION The Intermediate North School is located at 150 Intermediate N. Way in Toms River, New Jersey. This 178,300 SF facility was built in 1972 and is used as a public middle school. The hexagonal classroom C-wing is a two-story structure while the B-wing, D-wing and Common Areas are single-story. The facility is comprised of a main office, general classrooms, computer lab, gym, auxiliary gym, kitchen, cafetorium, faculty dining area, media center, SGI classrooms, nurse s office, restrooms, boiler room, HVAC penthouse, and utility/storage rooms. Occupancy Profile The typical hours of operation for the Intermediate North School are Monday through Friday between 7:00 am and 5:00 pm, with custodial staff on site afterhours till approximately 10:00 pm. Additional events occur throughout the year after hours in the facility. The school s normal operations span 10 months, with summer programs and community activities occurring during July and August. The school has an enrollment of 1,360 students and 150 staff. Building Envelope Exterior walls for the building are masonry brick faced with concrete block interior walls. The widow systems are single pane, operable, 1/8 glass with aluminum frames, are not thermally broken, and very energy inefficient. Many rubber gaskets on these aluminum framed windows were observed to be missing or falling out, which leads to air and water infiltration. Some windows are difficult to operate and do not lock properly. Perimeter sealants are failed and numerous muntins have pulled away from the glass. Worn weather-stripping, signs of some water damage, and air leakage were observed on several of the exterior doors. Blinds are utilized through the facility for occupant comfort. The blinds are valuable because they help to reduce heat loss in the winter and reduce solar heat gain in the summer. The windows throughout the school are in poor condition and should be replaced with new, energy efficient, commercial grade, thermally broken aluminum framed windows with low-e, insulated glass panels. Various roofing systems are installed at the school with a large portion of the roof consisting of modified bitumen roofing over asphalt and a mineral surface of white or brown granules. Another portion of the roof is a flat, built-up rubber roof with a brown water sealant sprayed over the rubber membrane. Another portion of the roof for this building is constructed of a built-up roof with rubber membrane and light color stone covering. The condition of the rubber membrane and the amount of insulation below the roof is unknown. HVAC Systems The facility is heated by a central hot water boiler plant located in the boiler room. Heating hot water is provided by two (2) Superior watertube, gas-fired boilers manufactured in 1988 with a rated input of 4,000 MBH and have an estimated thermal efficiency of 70% based on their condition and age.

19 ECM #1: Lighting Upgrade General Description: The majority of the interior lighting throughout the Intermediate North School is provided with fluorescent fixtures with older generation, 32W T8 lamps with electronic ballasts or 34W T12 lamps with magnetic ballasts. Additionally, there are several areas that still contain compact fluorescents and incandescent lamps. These fixtures can be replaced and retrofit with new LED type fixtures and lamps. This ECM includes replacing and retrofitting the interior lighting with new LED type lamps and fixtures. It is recommended the School District consult with a professional engineer prior to retrofitting or replacing fixtures to ensure code required minimum light levels will be met. 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.

21 ECM #2: Lighting Controls Upgrade Occupancy Sensors Description: Some of the lights in the Intermediate North 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 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. This ECM includes installation of ceiling or switch mount sensors for mostly classrooms and offices. 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.

25 ECM #4: Fire-Tube Boiler Replacement Description: The Intermediate North School has two (2) Superior bent-tube, gas-fired, hot water boilers that are 26 years old, and have not yet surpassed their ASHRAE useful life expectancy. While these units are still in operating condition, their overall efficiency has greatly diminished. The two boilers have a rated input capacity of approximately 4,000 MBH each with an estimated thermal efficiency of 70% due to their age and condition. This ECM would replace the two existing boilers with two (2) modular, condensing style boilers rated at 3,000 MBH each with an average thermal efficiency of 90%. The new boilers would come with hot water reset and outdoor air reset controls to reduce heating water temperature during low load periods. Savings Calculations: Savings were calculated utilizing the New Jersey Board of Public Utilities Protocols to Measure Resource Savings dated March, In order to evaluate the gas usage associated with the heating boilers only calculations were performed to estimate the usage of other heating equipment and domestic hot water. Based on the analysis the resultant breakdown of natural gas usage was determined for the facility.

28 ECM #5: High Efficiency Gas Hot Water Heater Description: The Intermediate North School has five areas which are served by separate hot water heaters. The main hot water heater, located in the main boiler room, is an A.O. Smith gas-fired heater, which serves everything except for the C-wing. In the C-wing penthouses, there are four Stonesteel electric hot water heaters which serve the respective area. The existing units have surpassed their ASHRAE service life, and upgrading to gas-fired high efficiency units may incur significant cost savings. This ECM will replace the A.O Smith and Stonesteel domestic water heaters with a Natural Gas fired Bradford White EF Series high efficiency water heaters or equal. (Before proceeding with installation of aforementioned system, Concord Engineering suggests consulting a plumber to evaluate the system fully.)

34 ECM #7: Vending Miser Controls Description: The Intermediate North School currently utilizes vending machines in select areas within the building. Vending machines are located in the faculty lunch room which can be in use for a limited time during the day. The installation of the Vending Miser system will help reduce the operating hours of vending machines. Cold beverage machines regularly operate inefficiently trying to maintain a constant cool temperature within the machine and snack machines with no cooling usually have lights that operate 24/7. The VendingMiser system incorporates innovative energy-saving technology into a small plug-and-play device that in conjunction with a passive infrared sensor regulate the operation of the cold beverage and snack machines based on occupancy and room temperature. This ECM approximates the installation of two (2) for the cold beverage machines and one (1) for the snack machine.

36 ECM #8: CRT Monitor Replacement Description: The Intermediate North School still utilizes CRT Monitors for use by its students. Typical CRT monitors throughout the building consist of 15 inch displays. These computer monitors are outdated and have several disadvantages such as; significantly higher energy consumption in operating and idle mode, use a large amount of desk space, poor picture quality, distortions and flickering image, secular glare problems, and high weight, and electromagnetic emissions. Many of the drawbacks are difficult to quantify except for the energy use. CRT monitors use considerably more energy than an alternative flat panel LCD/LED monitor. Replacement of the existing CRT monitors with LCD/LED monitors saves considerable energy as well as provides other ergonomic benefits as well. This ECM will replace all 58 existing CRT monitors with new 17 Dell LCD/LED. It is expected District IT Staff will purchase and install new monitors, therefore no labor costs were taken into account for this measure. Savings Calculations: Savings calculations were based on operating occupied hours per week of operating staff and students, and estimated idle time of monitors per week outside occupied hours. Power consumption data is based on actual monitor characteristics for a Dell CRT, and Dell LCD/LED.

39 ECM #9: Computer Power Management Description: The Intermediate North School currently has approximately 205 desktop computers throughout the classrooms, offices, and computer labs. Currently these computers are on all day during the week and shut down on weekends, during summer recess, and on long holidays. While the current operating procedure has its merits, by implementing a management program with power management and maintenance management while the buildings are unoccupied as well as designating on periods for software upgrades, and wake on LAN capability to boot computers up prior to student arrival significant energy savings could be achieved. This ECM recommends installing a computer maintenance management program with a power management option to turn computer on and off without the need for manual shutdowns by staff. The system being considered should be equivalent to a Dell KACE K1000. This will not only save the School on energy costs, but also benefit IT maintenance. Savings Calculations: Savings calculations were based on existing operating conditions observed in the field, in addition to the quantity, make, and model of desktop.

42 ECM #10: CRT TV Replacement Description: The Intermediate North School currently has older Cathode Ray Tube Televisions in its classrooms. These TV s are older technology and use a substantial amount of electricity when in use and also while powered off in idle power draw mode. The TV s appeared to be 25 screen size units; in general these units draw 95 watts or more of power while in use and 5 watts or more while in idle mode. Newer televisions such as Liquid Crystal Displays (LCD) or LED television, use power much more efficiently than older CRT models and in many cases draw nearly zero power while in idle mode. This ECM recommends that the school replace these older televisions with new LG 32 LED type units model 32LN530B or equal.

45 ECM #11: 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 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.

47 ECM #12: Water Conservation Description: The Intermediate North School utilizes standard plumbing fixtures. The typical water faucet consumption only meets the minimum federal required standard for water efficiency. New fixtures are available that use less water than today s requirements and can add up to significant water reduction over a long period. This ECM includes the retrofitting of the existing faucets within the facility with new low flow aerators. The estimated usage of the plumbing fixtures is based on the total population of the facility. The number of plumbing fixtures to be replaced is based on observations of the facility. (Please note that the estimate of occupants for the library is an estimate based on daily employees at the facility) The proposed retrofit includes installation of low flow aerators. For the basis of this calculation the LEED rating system was used to estimate the occupancy usage for students within the school. When water consumption information was not available, the GPF values were estimated for the existing fixtures.

50 ECM #13: Window Replacement Description: Several areas of the building envelope consist of single pane windows with aluminum frames. The total area of single pane windows for the main office area, B-wing and C-wing is estimated at 2,500 SF. This area was used as the basis for calculating energy savings and formulating a cost estimate. Older inefficient windows can account for significant energy use through leakage heat loss and conductive heat loss. The age and condition of the windows contribute to the leakage rate of the building. The single pane construction allows higher thermal (conductive) energy loss. These factors lead to increased energy use in the heating season. The heating loss due to single pane glass is combined with heat loss due to poor seals at each operable window. New double pane windows with low E glazing offer a substantial improvement in thermal performance throughout the year. This ECM includes the replacement of all single pane glass in the main office area, B-wing and C-wing with double pane windows with low emissivity glass. The proposed windows include reduced outside air leakage. In addition the double pane structure will significantly increase the insulation value compared to the existing single pane window structure. The basis for this ECM is an ASHRAE equivalent window. The windows will be replaced throughout the classroom wings. Savings Calculations: Thermal Loss values were calculated for each month based on the average monthly temperature obtained for 2013/2014. The heating period used was October to April.

53 ECM #14: Digital Management System (DDC EMS) Description: The Intermediate North School currently has pneumatic and electronic controls systems with no front end computer to operate the HVAC systems on in the building. The installation of a Central Management System to control the unit ventilators, exhaust fans, boilers and pumps could yield significant savings through setback and scheduling capability, and improved maintenance response time to outages and breakdowns. This ECM includes installation of a Building Automation system to include control of the HVAC equipment in the facility. The system will include new thermostats, new unit ventilator/baseboard control valves, exhaust fan on/off controllers, a front end computer and main controller. With the communication between the control devices and the front end computer interface, the facility manager will be able to take advantage of scheduling for occupied and unoccupied periods based on the actual occupancy of each space in the facility. The DDC system will also aid in the response time to service / maintenance issues when the facility is not under normal maintenance supervision, i.e. after-hours. The Central DDC system installation has the potential to provide significant savings by controlling the HVAC systems as a whole and provide operating schedules and features such as space averaging, night set-back, temperature override control, etc. The U.S. Department of 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 referenced report: Management and Control System Savings: 5%-15%. Savings resulting from the implementation of this ECM for energy management controls are estimated to be 5% of the electricity and 5% for the gas utility in this building. The basis for the DDC system expansion is the Andover Management System or similar. Savings Calculations: savings for each utility is calculated with the equation below.

56 ECM #15: High Efficiency Transformers Description: Electrical distribution transformers play a key role in delivering electrical power to buildings as all the electrical power supplied to the building flows through them. Whether equipment is plugged in and turned on or not transformers continue to operate. Consider their impact on electricity consumption. Some transformers waste as much as 20% of billed electricity. Older transformers in existing buildings may not have been built to meet the load requirements of today. Over the years electrical distribution has changed very little, however the connected equipment has changed dramatically. This dramatic change is derived from both the type of equipment (mostly electronic in nature) and the density of installed equipment. The impact of this change has had a direct impact on power quality and transformer efficiency. When newer electronic equipment is introduced into buildings with older electrical systems power quality and transformer efficiency can suffer. According to a Department of study performed in 1996 electronic equipment can increase losses by as much as 2.7 times. In real terms this would mean that a transformer that has a name- plate efficiency of 97% in reality is operating closer to 90% or lower. The difference represents additional costs to operate the transformer. Replacing your older transformers with Power smiths energy efficient E-Saver-C3 or T1000-C3 transformers can improve the reliability of your electronic equipment and significantly reduce electricity waste. Power smith s energy efficient transformers have substantially lower losses (higher efficiency) than other transformers. These energy savings mean less kilowatt-hours (kwh) consumed and lower energy bills. Electricity demand charges also decline, thanks to reduced energy losses. These savings pay for the transformer many times over its installed life. The Intermediate North School has two GE 45 kva, one GE 50 KVA, one GE 75 KVA and one GE 75 kva rated dry type transformers located in electrical rooms. The GE transformers are nearly 10 years old. This ECM would replace four transformers with new Power Smith energy efficient units. Savings Calculations: See Appendix for Manufacturers Transformer Calculation Spreadsheet.

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