I. EXECUTIVE SUMMARY

This report presents the findings of the energy audit conducted for:

South Hunterdon Regional School District 301 Mt. Airy Harbourton Road

Lambertville, New Jersey 08530 District Contact Person: Kerry Sevilis, Business Administrator

This audit is performed in connection with the New Jersey Clean Energy - Local Government Energy Audit Program for the South Hunterdon Regional High School. The purpose of this analysis is to provide the owner insight into the energy savings potential that exists within the facility. Energy Efficiency changes and upgrades requires support from the building occupants, operations personnel and the administrators of the building in order to maximize the savings and overall benefit. The efficiency improvement of public buildings provides a benefit for the environment and the residents of New Jersey. The Energy Conservation Measures (ECMs) identified within the report represent the potential annual savings at the facility. It is recommended to consider all ECMs as part of the BOE’s initiative to save energy, reduce emissions, and lower operating costs. The School District should review and be familiar with all measures presented in the report prior to making a decision on which projects to move forward with. This will enable the BOE to effectively align report recommendations with those outlined in their mid/long range facility plans and financial plans. The BOE should also review all conventional and unconventional funding, along with all NJCEP funding opportunities for these projects and determine which options fit their budget most positively in the short and long term. The combination of this information will enable the BOE to put together an effective Energy Savings Improvement Strategy that maximizes the received benefits of the selected projects. The annual energy costs at this facility are as follows: The potential annual energy cost savings for each energy conservation measure (ECM) and renewable energy measure (REM) are shown below in Table 1. Be aware that all ECM’s and REM’s are not additive because of the interrelation of some of the measures. This audit is consistent with an ASHRAE level 2 audit. The cost and savings for each measure is ± 20%. The evaluations are based on engineering estimations and industry standard calculation methods. More detailed analyses would require engineering simulation models, hard equipment specifications, and contractor bid pricing.

Overall Assessment: Overall, the South Hunterdon Regional High School is operating at a site energy use index (EUI) of 101 kBtu/SF per year which is above the average for high schools in the Northeast (see Figure 4). Concord Engineering recommends that the School District review and be familiar with all measures presented in the report prior to making a decision on which projects to move forward with. This will enable the School District to effectively align report recommendations with those outlined in their mid/long range facility plans and financial plans, of which the combination of this information will enable the School District to put together an effective Energy Savings Improvement Strategy that maximizes the received benefits of the selected projects. Other Considerations: Renewable Energy Conservation Measures: Renewable Energy Measures (REMs) were also reviewed for implementation at South Hunterdon High School. Concord Engineering utilized roof and ground mounted solar arrays to house PV systems at the facility. There is a total estimated solar system potential of 424 kW DC that could generate 514,658 kilowatt-hours annually offsetting 46% of the total energy purchased from the grid. The system’s calculated simple payback of 11.1 years is not within the standard 10 year simple payback threshold; however, with alternative funding this payback could be lessened. Concord Engineering recommends the Owner review all funding options available with the implementation of this renewable energy measure. Energy Procurement Recommendations: The School District is currently contracted with a third party supplier for the South Hunterdon High School for electric. It is recommended the School District continue utilizing a 3rd party purchasing approach to energy. The School District should also considering aggregating all of its properties to achieve greater savings through increases volume. Further recommendations are outlined in the Energy Procurement Section of this report that could assist the School District in finding additional savings through their utility bills. Maintenance and Operational Recommendations: In addition to the ECMs and REMs, there are maintenance and operational measures that can provide significant energy savings and provide immediate benefit. The ECMs listed above represent investments that can be made to the facility which are justified by the savings seen overtime. However, the maintenance items and small operational improvements below are typically achievable with onsite staff or maintenance contractors and in turn have the potential to provide substantial operational savings compared to the costs associated. The following are recommendations which should be considered a priority in achieving an energy efficient building and further recommendations for the building are provided in the building reports:



1. Chemically clean the condenser and evaporator coils periodically to optimize efficiency. Poorly maintained heat transfer surfaces can reduce efficiency 5-10%.

2. Maintain all weather stripping on windows and doors. 3. Clean all light fixtures to maximize light output. 4. Provide more frequent air filter changes to decrease overall system power usage and

maintain better IAQ. 5. Confirm that outside air economizers on the air handling units are functioning properly to

take advantage of free cooling and avoid excess outside air during occupied periods. 6. Verify all HVAC control systems are utilizing setback and scheduling capabilities.

Combined Project Approach: Although individual projects with a simple payback of 10 years and less are considered financially self-sustaining, it is important to consider how multiple projects can be combined together. When ECMs are aggregated into a single project, the lower cost ECMs provides valuable savings to offset the higher cost ECMs. Likewise when multiple facilities are aggregated together into a single entity energy efficiency project, the same benefits are seen on a larger scale. The Energy Savings Improvement Program (ESIP) allows for financing of any combination of energy efficiency projects across multiple facilities into one large project. The term of the financing must be under 15 years and the savings provides the revenue for the financing cost. The combination of all projects into one large energy efficiency project provides the opportunity to implement many of the ECMs identified within this report with an overall simple payback of 10.4 years. The total Entity Project Summary table below shows the savings, costs, incentives and paybacks for all of the ECMs found in Table 1.

II. INTRODUCTION This audit is performed in connection with the New Jersey Clean Energy - Local Government Energy Audit Program. The energy audit is conducted to promote the mission of the office of Clean Energy, which is to use innovation and technology to solve energy and environmental problems in a way that improves the State’s economy. This can be achieved through the wiser and more efficient use of energy. Electrical and fuel oil utility information were collected and analyzed for one full year’s energy use of the building. The utility information allows for analysis of the building’s operational characteristics; calculate energy benchmarks for comparison to industry averages, estimated savings potential, and baseline usage/cost to monitor the effectiveness of implemented measures. A computer spreadsheet was used to calculate benchmarks and to graph utility information (see the utility profiles below). The Energy Use Index (EUI) is established for the building. Energy Use Index (EUI) is expressed in British Thermal Units/square foot/year (BTU/ft2/yr), which is used to compare energy consumption to similar building types or to track consumption from year to year in the same building. The EUI is calculated by converting the annual consumption of all energy sources to BTU’s and dividing by the area (gross square footage) of the building. Blueprints (where available) are utilized to verify the gross area of the facility. The EUI is a good indicator of the relative potential for energy savings. A low EUI indicates less potential for energy savings, while a high EUI indicates poor building performance therefore a high potential for energy savings. Existing building architectural and engineering drawings (where available) are utilized for additional background information. The building envelope, lighting systems, HVAC equipment, and controls information gathered from building drawings allow for a more accurate and detailed review of the building. The information is compared to the energy usage profiles developed from utility data. Through the review of the architectural and engineering drawings a building profile can be defined that documents building age, type, usage, major energy consuming equipment or systems, etc. The preliminary audit information is gathered in preparation for the site survey. The site survey provides critical information in deciphering where energy is spent and opportunities exist within a facility. The entire site is surveyed to inventory the following to gain an understanding of how each facility operates:

• Building envelope (roof, windows, etc.) • Heating, ventilation, and air conditioning equipment (HVAC) • Lighting systems and controls • Facility-specific equipment

The building site visit is performed to survey all major building components and systems. The site visit includes detailed inspection of energy consuming components. Summary of building occupancy schedules, operating and maintenance practices, and energy management programs provided by the building manager are collected along with the system and components to determine a more accurate impact on energy consumption.

III. METHOD OF ANALYSIS This audit is consistent with an ASHRAE level 2 audit. The cost and savings for each measure is ± 20%. The evaluations are based on engineering estimations and industry standard calculation methods. More detailed analyses would require engineering simulation models, hard equipment specifications, and contractor bid pricing. Post site visit work includes evaluation of the information gathered, researching possible conservation opportunities, organizing the audit into a comprehensive report, and making recommendations on HVAC, lighting and building envelope improvements. Data collected is processed using energy engineering calculations to anticipate energy usage for each of the proposed energy conservation measures (ECMs). The actual building’s energy usage is entered directly from the utility bills provided by the owner. The anticipated energy usage is compared to the historical data to determine energy savings for the proposed ECMs. It is pertinent to note, that the savings noted in this report are not additive. The savings for each recommendation is calculated as standalone energy conservation measures. Implementation of more than one ECM may in some cases affect the savings of each ECM. The savings may in some cases be relatively higher if an individual ECM is implemented in lieu of multiple recommended ECMs. For example implementing reduced operating schedules for inefficient lighting will result in a greater relative savings. Implementing reduced operating schedules for newly installed efficient lighting will result in a lower relative savings, because there is less energy to be saved. The Combined Project Summary Table is based on the implementation of multiple measures. The analysis is reviewed and determined if the nature of the ECMs will cause a major conflict of the overall savings. When additive measures do not cause a major effect on the overall savings the ECMs are included. Where a major conflict is identified, the combined savings is evaluated appropriately to ensure the overall estimates are ± 20%. ECMs are determined by identifying the building’s unique properties and deciphering the most beneficial energy saving measures available that meet the specific needs of the facility. The building construction type, function, operational schedule, existing conditions, and foreseen future plans are critical in the evaluation and final recommendations. Energy savings are calculated based on industry standard methods and engineering estimations. Energy consumption is calculated based on manufacturer’s cataloged information when new equipment is proposed. Cost savings are calculated based on the actual historical energy costs for the facility. Installation costs include labor and equipment costs to estimate the full up-front investment required to implement a change. Costs are derived from Means Cost Data, industry publications, and local contractors and equipment suppliers. The NJ Smart Start Building® program incentives savings (where applicable) are included for the appropriate ECM’s and subtracted from the installed cost. Maintenance savings are calculated where applicable and added to the energy savings for each ECM. The life-time for each ECM is estimated based on the typical life of the equipment being replaced or altered. The costs and savings are applied and a simple payback, simple lifetime savings, and simple return on investment are calculated. See below for calculation methods:

FUEL OIL USAGE SUMMARY



Figure 3 #2 Fuel Oil Usage Profile



B. 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. The Oak Ridge National Laboratory (ORNL) Buildings Technology Center under a contract with the U.S. Department of Energy maintains a Benchmarking Building Energy Performance Program. The ORNL website determines how a building’s energy use compares with similar facilities throughout the U.S. and in a specific region or state. 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:

C. EPA Energy Benchmarking System The United States Environmental Protection Agency (EPA) in an effort to promote energy management has created a system for benchmarking energy use amongst various end users. The benchmarking tool utilized for this analysis is entitled Portfolio Manager. The Portfolio Manager tool allows tracking and assessment of energy consumption via the template forms located on the ENERGY STAR website (www.energystar.gov). The importance of benchmarking for local government municipalities is becoming more important as utility costs continue to increase and emphasis is being placed on carbon reduction, greenhouse gas emissions and other environmental impacts. Based on information gathered from the ENERGY STAR website, Government agencies spend more than $10 billion a year on energy to provide public services and meet constituent needs. Furthermore, energy use in commercial buildings and industrial facilities is responsible for more than 50 percent of U.S. carbon dioxide emissions. It is vital that local government municipalities assess facility energy usage, benchmark energy usage utilizing Portfolio Manager, set priorities and goals to lessen energy usage and move forward with priorities and goals. In accordance with the Local Government Energy Audit Program, Concord has created an ENERGY STAR account for the municipality to access and monitoring the facility’s yearly energy usage as it compares to facilities of similar type. The login page for the account can be accessed at the following web address; the username and password are also listed below:

VII. ENERGY CONSERVATION MEASURES ECM #1: Lighting Upgrade – General Description: The majority of the interior lighting throughout the South Hunterdon Regional High School is provided by fluorescent fixtures with the latest T-5 lamps and electronic ballasts. Several of these spaces have higher than average light levels and can be de-lamped to save energy. There are several areas that have the older T-12 lamps and ballasts that can be retrofitted to the T-5 system. In addition to the fluorescent tube lamps, there are additional fixture types consisting of metal halide, compact fluorescent, and incandescent lamps that can be retrofitted to LED style lamps. This ECM includes retrofitting the balance of the T-12 fixtures to the T-5 lighting system. The two gyms would be upgraded to the appropriate LED HiBay lighting fixtures. The incandescent lamps retrofitted to LED types. 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 – Exterior Lighting Description: The exterior lighting at South Hunterdon High School is currently lit by high pressure sodium and metal halide fixtures. The exterior would be better served with more efficient LED lighting system. Concord Engineering recommends upgrading the lighting to an energy-efficient LED lighting system that includes LED lamps and fixtures for the existing exterior lighting. This ECM would replace the existing exterior lamps and fixtures with equivalent LED lamps and fixtures. 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 South Hunterdon High 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. This ECM includes installation of ceiling or switch mount sensors for offices, classrooms, 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 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 #5: Vending Miser Controls Description: The school currently utilizes cold beverage and snack vending machines. Vending machines are usually used for a limited time during the day. The installation of the Vending Miser system will help reduce the operating hours of the 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. The device also monitors the room’s temperature and automatically re-powers the cooling system in the beverage machine to ensure that the product stays cold. For the cold beverage machines, the controllers will never power down the machine while the compressor is running so as to prevent compressor short-cycling. The cooling cycle is allowed to finish before powering down the compressor. This ECM would install four (4) of these control systems, two (2) for the snack machines and two (2) for the cold beverage machines. Energy Savings Calculations:

ECM #6: Walk-In Cooler/Freezer Controls The High School has three walk-in coolers/freezers that store food for the kitchen. Each box has an evaporator with fans to circulate cold air, three in the refrigerators, and two in the freezer. These fans operate continuously whether the compressor is on or off resulting in unnecessary heat buildup in the box due to the fan motors. This measure would install an evaporator fan controller that features two-speed operation of the evaporator fans – high speed during cooling, and low speed or off when not cooling manufactured by Frigitek or equivalent.

ECM #9: Building Weatherization A detailed survey was conducted to review potential building envelope upgrades around the entire facility. Leaky doors and windows, poorly sealed window air conditioner openings, lack of weather stripping, un-insulated loading dock doors, improperly adjusted door closers, weather stripping missing on overhead doors, etc. can all contribute to infiltration of cold or hot/humid air. For some of the perimeter doors, the weather stripping is worn and/or the door is the square in the frame allowing infiltration to enter conditioned spaces. Concord Engineering recommends replacing all old weather stripping on perimeter doors and re-caulking of various roof penetrations. This ECM involves sealing leaks in the building envelope with various weatherproofing measures such as caulking, weather stripping exterior doors, spray foam insulation and other techniques. The following measures are recommended:

1. Weather strip and adjust closers and latches on 10 single doors 2. Weather strip and adjust closers and latches on 20 double doors 3. Several entrances need to be air sealed above the doorways 4. Seal 16 roof penetrations

Savings for the building envelope upgrade are based on reducing air infiltration. The standard crack method was used for calculations and is outlined below: Standard Method Calculation Infiltration Rates: Q = k x (dP)^n x A k = 22 Average Daily Temperature Differential (dP) )^n = 6 Average Pressure Difference Across Envelope Boundary A = 1.00 Area of Infiltration Reduction Savings $ = Q x DD x Price per mmBTU / 28,900 Construction costs for the above air sealing services were obtained from ZeroDraft Company of New York and include a turnkey project for $10,000.

ECM #10: Demand Controlled Ventilation Description: The High School and Middle School Commons were identified as good candidates for the installation of Demand Controlled Ventilation (DCV) given their varied occupancy levels throughout the day. CO2 – based DCV when properly applied in spaces where occupancies vary below design occupancy, can reduce unnecessary over-ventilation while implementing the minimum air requirements of ASHRAE Standard 62. This ECM includes the installation of the additional Siemens APOGEE standalone controls, CO2 sensors, and programming needed in order to operate the active CO2 ventilation. There is currently one rooftop unit that serves the High School Commons (RTU-7, 5,500 CFM) and one rooftop unit that serves the Middle School Commons (RTU-2, 4,000 CFM) with hot water and chilled water coils. Energy Savings Calculations: Energy savings calculations are based on New Jersey Board of Public Utilities Protocols to Measure Resource Savings. The energy savings are calculated by using the existing efficiency rating and stipulated values in the protocols for operating hours and Heating Degree Days. The protocol stipulates that savings is equal to 5% of the total HVAC Energy for heating and cooling of the affected units.

ECM # 11: Domestic Hot Water Reset Description: The domestic hot water for this facility is supplied by an indirect water heater (a tank with a coil) that is heated using an oil-fired water heater by A. O. Smith. During the energy audit site inspections, it was observed that the domestic hot water supply was at 160°F and the return temperature was 120°F. During most of the year, 160°F supply water is not required for domestic hot water needs. The domestic hot water supply can be lowered to 150°F and save appreciable fuel oil costs. In addition, short cycling of the water heater (water heater turns on for a very short period of time) was observed. Reduction in water heater efficiency and longevity has been attributed to water heater cycling. This ECM would install outdoor temperature reset by installation of upgraded temperature sensors, and a reset controller. The basis of design for the controller is the Honeywell Model W8735S AquaReset®. Energy Savings Calculations: The energy savings are calculated for reducing the domestic hot water supply temperature by 10°F most of the year based on outdoor temperature reset. For each degree of hot water supply reduction, a 1% reduction in energy costs can be obtained. The oil-fired water heater has a rated input of 385 MBH and a 10% savings would equal 38.5 MBH. It is assumed that the Equivalent Full Load Hours (EFLH) is 1,000 so that the energy savings is 38,500 MBTU. Dividing this number by 139 MBTU (for #2 fuel oil) equals 276 gallons saved x $3.52 per gallon = $974 in energy cost savings. The cost of the Honeywell Model W8735S AquaReset® along with upgraded temperature sensors, installation and programming is estimated to be $8,000.

ECM #12: Domestic Water Heater Controller/Timer Description: The domestic hot water system at the high school consists of an oil-fired water heater rated for 385 MBH input capacity which feeds a coil inside a storage tank with a capacity of 700 gallons. Although the storage tank is insulated, there are significant standby losses during unoccupied hours. The oil-fired water heater turns on throughout unoccupied hours to maintain the desired set point temperature. Concord Engineering recommends installing a controller/timer on the system to turn off the system during unoccupied hours and turn the domestic hot water system back on two hours before the building becomes occupied. Energy Savings Calculations: Assume that the water heater is turned off for 8 hours per day, 7 days per week = 2,920 hours/yr. The thermal efficiency (TE) of the oil-fired water heater is 78%. From ASHRAE 90.1-2007 Table 7.8, the standby losses (SL) are _ ___ SL = 78% Et (Q/800 + 110 √V) = 0.78(385,000 BTUH/800 + 110 √700 gallons) = 3,390 BTUH (3,390 BTUH x 2,920 hours/yr.) / 139,000 BTU/Gal #2 Fuel Oil = 71.2 gallons/yr. #2 Fuel Oil Savings = 71.2 gallons x $3.52/gallon = $250.60

REM #1: 424.32 kW Solar System Description: The South Hunterdon Regional High School has available roof and ground space that could accommodate solar arrays. Based on the available area a 424.32 kilowatt solar array could be installed. The array will produce approximately 514,658 kilowatt-hours annually that will reduce the overall electric usage of the facility by 46%. The owner should consult a structural engineer prior to installing any solar array to insure the roof can accommodate the additional weight. 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:

REM #1 - ENERGY SAVINGS SUMMARY



VIII. RENEWABLE/DISTRIBUTED ENERGY MEASURES Globally, renewable energy has become a priority affecting international and domestic energy policy. The State of New Jersey has taken a proactive approach, and has recently adopted in its Energy Master Plan a goal of 30% renewable energy by 2020. To help reach this goal New Jersey created the Office of Clean Energy under the direction of the Board of Public Utilities and instituted a Renewable Energy Incentive Program to provide additional funding to private and public entities for installing qualified renewable technologies. A renewable energy source can greatly reduce a building’s operating expenses while producing clean environmentally friendly energy. Concord Engineering has assessed the feasibility of installing renewable energy measures (REM) for the municipality utilizing renewable technologies and concluded that there is potential for solar energy generation. Solar Generation Solar energy produces clean energy and reduces a building’s carbon footprint. This is accomplished via photovoltaic panels which are mounted on all south and southwestern facades of the building. Flat roof, as well as sloped areas can be utilized; flat areas will have the panels turned to an optimum solar absorbing angle. (A structural survey of the roof would be necessary before the installation of PV panels is considered). The state of NJ has instituted a program in which one Solar Renewable Energy Certificate (SREC) is given to the Owner for every 1000 kWh of generation. SREC’s can be sold anytime on the market at their current market value. The value of the credit varies upon the current need of the power companies. The average value per credit is around $191, this value was used in our financial calculations. This equates to $0.191 per kWh generated. Wind Generation In addition to evaluating solar, Concord also conducted a review of the applicability of wind energy for the South Hunterdon Regional School District. Wind energy production is another option available as a clean renewable energy generating source. Wind turbines of various types can be utilized to produce clean energy on a per building basis. Cash incentives are available per kWh of electric generated. Concord investigated the potential for smaller building mountable wind turbines, and horizontal turbines to maximize the available free space. In order to be economically viable a site requires a minimum average wind speed of 6 meters per second (13.5 mph). Based on the obtained wind data shown in Figure 4 for Trenton (closest location with data available) the annual average wind speed is 9.8 mph with a peak of 11.2 mph, making this area unattractive for wind development. Therefore, wind energy is not a viable option to implement.



Figure 4: Monthly Wind Speed (Trenton, New Jersey)



IX. ENERGY PURCHASING AND PROCUREMENT STRATEGY Load Profile: Load Profile analysis was performed to determine the seasonal energy usage of the facilities. Irregularities in the load profile will indicate potential problems within the facilities. Consequently based on the profile a recommendation will be made to remedy the irregularity in energy usage. For this report, the facilities energy consumption data was gathered in table format and plotted in graph form to create the load profile. Refer to The Electric and #2 Fuel Oil Usage Profiles included within this report to reference the respective electricity and #2 Fuel Oil usage load profiles. Electricity: The electricity usage profile demonstrates a relatively steep load profile from winter to summer. The average summer (May-September) consumption is 30% more than the average winter (October-April) consumption. The following table outlines the seasonal average monthly consumption and demand for the facility.

Tariff Analysis: Electricity: The facility receives electrical service from Jersey Central Power and Light (JCPL) on rate schedules GS3 (General Service Secondary 3 phase). The facility has contracted a Third Party Supplier (TPS) to provide electric commodity service. Hess Corporation has been contracted however; the contract particulars such as product structure, price, term and conditions were not available for review or comments. Each year since 2002, the four New Jersey Electric Distribution Companies (EDCs) - Public Service Gas & Electric Company (PSE&G), Atlantic City Electric Company (ACE), Jersey Central Power & Light Company (JCP&L), and Rockland Electric Company (RECO) - have procured several billion dollars of electric supply to serve their Basic Generation Service (BGS) customers through a statewide auction process held in February.

WINTER (OCT - APR) SUMMER (MAY - SEP)



BGS refers to the service of customers who are not served by a third party supplier or competitive retailer. This service is sometimes known as Standard Offer Service, Default Service, or Provider of Last Resort Service. The Auction Process has consisted of two auctions that are held concurrently, one for larger customers on an hourly price plan (BGS-CIEP) and one for smaller commercial and residential customers on a fixed-price plan (BGS-FP). This facility’s rate structure is based on the fixed-price plan (BGS-FP). The utility will continue to be responsible for maintaining the existing network of wires, pipes and poles that make up the delivery system, which will serve all consumers, regardless of whom they choose to purchase their electricity or natural gas from. PSEG’s and ACE’s delivery service rate includes the following charges: Customer Service Charge, Distribution Charge (kWh and Demand), Societal Benefits Charge (SBC), and Securitization Transition Charge.

Commodities Market Overview:

Current electricity and natural gas market pricing has remained relatively stable over the last couple of years. Commodity pricing in 2008 marked historical highs in both natural gas and electricity commodity. Commodity pricing commencing spring of 2009 continuing through 2013, has decreased dramatically over 2008 historic highs and continues to be favorable for locking in long term (2-5 year) contracts with 3rd Party Supplier’s for both natural gas and electricity supply requirements.

It is important to note that both natural gas and electric commodity market prices are moved by supply and demand, political conditions, market technicals and trader sentiment. This market is continuously changing. Energy commodity pricing is also correlated to weather forecasts. Because weather forecasts are dependable only in the short-term, prolonged temperature extremes can really cause extreme price swings.

Short Term Energy Outlook - US Energy Information Administration:

Electricity

The Northeastern United States experienced a strong heat wave during mid-July of 2013. In response, many customers ran their air conditioners more than usual. EIA estimated that the average commercial customer in New England used about 1.0 percent more electricity during the summer of 2013 (June-August) compared with the previous summer, while commercial customers in the Middle Atlantic states used about 0.5 percent more electricity. In addition to increased electricity demand, the heat wave also caused temporary spikes in wholesale power prices. State retail rate regulations shield many commercial customers from price swings in the wholesale power market, but EIA expects summer electricity prices in the Northeast to average about 2.7 percent higher than summer 2013, primarily as a result of higher fuel costs paid by generators.



Generation fuel costs and wholesale electricity prices have increased in 2013 after a considerable decline in 2012. During the first half of 2014, EIA estimates the price of natural gas delivered to electric generators will average $4.46 per MMBtu, 44 percent higher than the same period last year. Changes in the costs of providing electricity are not immediately reflected on retail customer bills because state regulatory commissions must approve rate changes in many areas of the country. EIA expects the retail price of electricity in 2014 will average 12.1 cents per kilowatt-hour, about 1.9 percent higher than the price the previous year.

The below recommendations presented by Concord Engineering are based on current information provided by the District for their high school historical energy usage. Any savings presented with these recommendations are estimates only based on that information. It is recommended that further analysis and review of more recent utility data and actual TPS electricity supply contracts and historical billings be performed prior to performing any of the presented recommendations. Recommendations:

1. Concord recommends the district continue its aggregation approach for 3rd party commodity supply procurement strategies for the purchase of electricity. Aggregating the usage of all School District facilities for electricity supply service, allows the District to continue to achieve lower prices in commodity supply costs over the utility default service programs.

2. After review of the utility consumption report and current commodity pricing outlook, Concord recommends that the District utilize the advisement of a 3rd party unbiased Energy Consulting Firm licensed by the State of New Jersey Board of Public Utilities that is experienced in the procurement of commodities, New Jersey procurement laws, aggregation of facilities and energy supply risk and commodity management. This firm should be able to provide full service advisement over the term of the contract, provide market watch opportunities and identify any additional opportunities that may further reduce costs. Many of these opportunities may include: energy rates; utility bill auditing; energy data analytics; and efficiency improvements. It is important that a rational, defensible strategy for purchasing commodity in volatile markets is incorporated. Examples include:

• Budgets that reflect sound market intelligence • An understanding of utility and market historical prices and trends • Awareness of seasonal opportunities (e.g. shoulder months) • Negotiation of fair contractual terms • An aggressive, market based price

3. Concord recommends that the District review their current situation regarding third party

purchasing for electricity. The District should review their current contract particulars and future pricing to formulate a strategy to optimize cost savings.



Concord also recommends that the District consider utilizing a third party utility billing-auditing service to further analyze historical utility invoices such as water, sewer, electricity and solar for incorrect billings and rate tariff optimization services. This service can be based on a shared savings model with no direct cost. The service could provide refunds on potential incorrect billings that may have been passed through by the utilities and paid by the School District.



X. INSTALLATION FUNDING OPTIONS CEG has reviewed various funding options for the facility owner to utilize in subsidizing the costs for installing the energy conservation measures noted within this report. Below are a few alternative funding methods:

A. Incentive Programs: Pay For Performance The New Jersey Smart Start Pay for Performance program includes incentives based on savings resulted from implemented ECMs. The program is available for all buildings that were audited as part of the NJ Clean Energy’s Local Government Energy Audit Program. The facility’s participation in the program is assisted by an approved program partner. An “Energy Reduction Plan” is created with the facility and approved partner to shown at least 15% reduction in the building’s current energy use. Multiple energy conservation measures implemented together are applicable toward the total savings of at least 15%. No more than 50% of the total energy savings can result from lighting upgrades / changes.

Total incentive is capped at 50% of the project cost. The program savings is broken down into three benchmarks; Energy Reduction Plan, Project Implementation, and Measurement and Verification. Each step provides additional incentives as the energy reduction project continues. The benchmark incentives are as follows:

1. Energy Reduction Plan – Upon completion of an energy reduction plan by an approved program partner, the incentive will grant $0.10 per square foot between $5,000 and $50,000, and not to exceed 50% of the facility’s annual energy expense. (Benchmark #1 is not provided in addition to the local government energy audit program incentive.)

2. Project Implementation – Upon installation of the recommended measures along with the “Substantial Completion Construction Report,” the incentive will grant savings per KWH or Therm based on the program’s rates. Minimum saving must be 15%. (Example $0.11 / kWh for 15% savings, $0.12/ kWh for 17% savings, … and $1.10 / Therm for 15% savings, $1.20 / Therm for 17% saving, …) Increased incentives result from projected savings above 15%.

3. Measurement and Verification – Upon verification 12 months after implementation of all recommended measures, that actual savings have been achieved, based on a completed verification report, the incentive will grant additional savings per kWh or Therm based on the program’s rates. Minimum savings must be 15%. (Example $0.07 / kWh for 15% savings, $0.08/ kWh for 17% savings, … and $0.70 / Therm for 15% savings, $0.80 / Therm for 17% saving, …) Increased incentives result from verified savings above 15%.



Smart Start Program

Prescriptive Measures - The New Jersey Clean Energy’s Smart Start prescriptive measures incentives include unit pricing incentives for installation of energy efficient equipment and controls. Proposed equipment and controls must meet the minimum efficiency requirements as well as other application requirements. The Smart Start prescriptive incentives applicable for new construction, renovations, remodeling and equipment replacements, for a wide range of equipment including:

• Electric Chillers • Gas Cooling • Electric Unitary HVAC • Ground Source Heat Pumps • Gas Heating • Variable Frequency Drives • Gas Water Heating • Premium Motors • Prescriptive Lighting • Lighting Controls • Technical Studies

Custom Measures - The New Jersey Clean Energy’s Smart Start prescriptive measures incentives include all measures not identified in the prescriptive measures category or measures that must have savings verified through additional analysis such as energy model simulations. Custom measures are intended to include savings as a result of unique energy efficiency measures, which are typically facility specific such as waste heat recovery. Custom incentives are provided based on the amount of energy saved and minimum internal rate of return in order to be eligible.

CEG recommends the Owner review the use of the above-listed funding options in addition to utilizing their standard method of financing for facilities upgrades in order to fund the proposed energy conservation measures.



B. Financing Options: Municipal Bonds Municipal bonds are a bond issued by a city or other local government, or their agencies. Potential issuers of municipal bonds include cities, counties, redevelopment agencies, school districts, publicly owned airports and seaports, and any other governmental entity (or group of governments) below the state level. Municipal bonds may be general obligations of the issuer or secured by specified revenues. Interest income received by holders of municipal bonds is often exempt from the federal income tax and from the income tax of the state in which they are issued, although municipal bonds issued for certain purposes may not be tax exempt. Power Purchase Agreement Public Law 2008, Chapter 3 authorizes contracts of up to fifteen (15) years for energy purchase contracts commonly known as “power purchase agreements.” These are programs where the contracting unit (Owner) procures a contract for, in most cases, a third party to install, maintain, and own a renewable energy system. These renewable energy systems are typically solar panels, windmills or other systems that create renewable energy. In exchange for the third party’s work of installing, maintaining and owning the renewable energy system, the contracting unit (Owner) agrees to purchase the power generated by the renewable energy system from the third party at agreed upon energy rates. Energy Savings Improvement Program (ESIP): Public Law 2009, Chapter 4 authorizes government entities to make energy related improvements to their facilities and pay for the costs using the value of energy savings that result from the improvements. The “Energy Savings Improvement Program (ESIP)” law provides a flexible approach that can allow all government agencies in New Jersey to improve and reduce energy usage with minimal expenditure of new financial resources. This program provides public entities to make valuable facility infrastructure improvements that are associated with energy savings. All energy savings projects are eligible as long as the financing period does not extend beyond 15 years. The financing can be utilized for all aspects of energy efficiency project implementation including, energy savings plan development, engineering, construction management, construction management, commissioning, and measurement and verification. This program provides the much needed financing for energy efficiency projects without the burden of increased debt. The program allows for procurement of financing without voter approval or extending existing dept. The program requires evaluation to ensure a positive cash-flow through the entire 15 year financing period. The first phase of implementing an ESIP is the development of an Energy Savings Plan (ESP) to verify the energy savings, construction costs, and overall financial model. The underlining program requirement is the limitation of the project term to 15 years. The ESIP project size is open for multiple buildings to be included within one project. In addition all applicable incentive programs can also be utilized to help reduce the overall construction cost. Concord Engineering Group, Inc. 1C13406 February 25, 2014 – FINAL Page 63 of 65


XI. ADDITIONAL RECOMMENDATIONS In addition to the ECMs and REMs, there are maintenance and operational measures that can provide significant energy savings and provide immediate benefit, many of which facility’s staff are already performing. Maintenance items and small operational improvements are typically achievable with on-site staff or maintenance contractors and in turn have the potential to provide substantial operational savings compared to the costs associated. The following are recommendations which should be considered a priority in achieving an energy efficient building

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. Confirm that outside air economizers on the air handling units are functioning properly to take advantage of free cooling and avoid excess outside air during occupied periods.

F. Perform annual steam trap surveys to minimize energy waste caused by failed traps, and to maintain an inventory of system equipment.

G. Verify all HVAC control systems are utilizing setback and scheduling capabilities.

H. Shutdown all non-essential equipment during unoccupied periods.



XII. ENERGY AUDIT ASSUMPTIONS The assumptions utilized in this energy audit include but are not limited to following:

A. Cost Estimates noted within this report are based on industry accepted costing data such as RS MeansTM Cost Data, contractor pricing and engineering estimates. All cost estimates for this level of auditing are +/- 20%. Prevailing wage rates for the specified region has been utilized to calculate installation costs. The cost estimates indicated within this audit should be utilized by the owner for prioritizing further project development post the energy audit. Project development would include investment grade auditing and detailed engineering.

B. Energy savings noted within this audit are calculated utilizing industry standard procedures and accepted engineering assumptions. For this level of auditing, energy savings are not guaranteed.

C. Information gathering for each facility is strongly based on interviews with operations personnel. Information dependent on verbal feedback is used for calculation assumptions including but not limited to the following:

a. operating hours b. equipment type c. control strategies d. scheduling

D. Information contained within the major equipment list is based on the existing owner documentation where available (drawings, O&M manuals, etc.). If existing owner documentation is not available, catalog information is utilized to populate the required information.

E. Equipment incentives and energy credits are based on current pricing and status of rebate programs. Rebate availability is dependent on the individual program funding and applicability.

F. Equipment (HVAC, Plumbing, Electrical, & Lighting) noted within an ECM recommendation is strictly noted as a basis for calculation of energy savings. The owner should use this equipment information as a benchmark when pursuing further investment grade project development and detailed engineering for specific energy conservation measures.

G. Utility bill annual averages are utilized for calculation of all energy costs unless otherwise noted. Accuracy of the utility energy usage and costs are based on the information provided. Utility information including usage and costs is estimated where incomplete data is provided.

H. Greenhouse Gas Emissions are calculated for each ECM, the basis for these emissions reductions are NJCEP published standard emissions factors, which are the following:.

a. Electric Savings: 1. CO2: 1.52 lbs/kWh 2. NOX: 0.0028 lbs/kWh 3. SO2: 0.0065 lbs/kWh

b. Natural Gas Savings: 1. CO2: 11.7 lbs/therm 2. NOX: 0.0092 lbs/therm
