The Energy Conservation Measures (ECMs) identified within the report represents the potential annual savings at the facility. It is recommended to consider all ECMs as part of the school district’s initiative to save energy, reduce emissions, and lower operating costs. Concord Engineering Group (CEG) recommends proceeding with the implementation of all ECM’s that provide a calculated simple payback at or under ten (10) years. All of the ECM’s presented in this report have been categorized into three groups defined as Short-term (or Fast) Paybacks ranging from 0 to 5 years, Medium-term Paybacks ranging from 5 to 10 years, and Long-term Paybacks of over 10 years to assist the District in prioritizing projects.

Short-term Payback Energy Conservation Measures:

The following Energy Conservation Measures (ECMs) identified with a simple payback of 0 to 5 years are considered very cost effective and should be considered a high priority for the District. It should be noted that in many cases ECM’s lying in this range can be performed utilizing qualified “in house” staff that can further reduce the payback period.

• ECM #4: Demand Control Ventilation in Gym & Cafeteria Active demand control ventilation allows the modulation of outside air in the system depending on occupancy. The cafeteria and gymnasium are occupied intermittently throughout the day and are currently being monitored by CO2 sensors in the return air ducts. Setting these already build in controls to “Active” could allow the facility to see savings.

• ECM #5: HVAC Schedule Adjustments The use of a controls contractor in adjusting the setting for the HVAC system could have significant savings. Currently the building is operating on a more aggressive controls scheme, while setting back certain temperatures to a more conservative level could help the system run at an optimal level. In addition to temperature adjustments, the school could look further into changing the run times for occupied and unoccupied settings to see greater savings.

• ECM #7: Lighting Upgrade Lighting retrofits throughout the facility is a straight forward conservation measure that is prescriptive in nature and provides substantial savings for the investment. Lighting retrofits are a good example of ECMs that can be implemented with qualified “in house” staff to reduce the installation cost and further reduce paybacks. Throughout most of the school the measure includes replacing existing 700 series T-8 fluorescent lamps with new higher efficiency T-8 lamps. This upgrade also includes installation of high bay T-5 fixtures to replace the existing metal halide fixtures. In addition it is recommended to utilize CFL lamps in lieu of all existing incandescent lamps throughout the school district. Overall lighting upgrades represent one of the most easily implemented ECMs and are highly recommended.



• ECM #8: Lighting Controls Similar to lighting upgrades, lighting controls are very simple upgrades and can save considerable energy. Lighting controls do not require replacement of the fixture and typically can save more energy than lighting upgrades alone. Lighting controls will automatically turn off lights when spaces and rooms are not occupied. Lighting controls provide the maximum savings in spaces that have changing occupancy schedules throughout the day such as the classrooms after school hours, labs, music rooms, media centers, etc. Lighting controls is highly recommended in addition to the lighting upgrade ECMs. (It is important to note that ECMs are calculated as stand-alone ECMs and therefore the total savings will be slightly less than the sum of both individual ECMs (Lighting Upgrade and Lighting Controls). The discrepancy between additive ECMs is within the tolerances for this level of analysis (+/- 20%).)

Medium-term Payback Energy Conservation Measures:

The following Energy Conservation Measures (ECMs) identified with a simple payback of 5 to 10 years are considered cost effective and should be considered by the District. In many cases these measures can provide significant savings, however the costs to implement are higher, stretching the payback beyond five years.

• ECM #3: Replace CRT Monitors Modern computer monitors are flat screen LCD panels that are far more efficient than older style cathode ray-tube (CRT) monitors. Typical energy use of a flat screen monitor is approximately 1/3 of the energy used by a CRT monitor. A large portion of the computer monitors throughout the facility are CRT style monitors. This represents a significant energy savings potential. It is recommended to replace the existing CRT monitors with flat screen monitors to take advantage of the energy savings as well as other ergonomic benefits of modern LCD monitors.

• ECM #6: Occupancy Controlled Power Strips Plug loads within buildings are becoming a larger and larger portion of the total energy use all types of facilities. Plug loads are most dominant in combination with computers and computer equipment. The installation of occupancy controlled power strips would allow daily occurrences such as a fully run computer system for the complete duration of the day to become reduced and turned off while no one is operating the computer system. It is recommended the District review implementation of this ECM especially in computer labs and offices where computer and computer accessories are left on during long periods of unoccupied times.



Long-term Payback Energy Conservation Measures:

The following Energy Conservation Measures (ECMs) identified with a simple payback of over 10 years. The ECMs that have much longer paybacks are considered capital improvement ECMs. These typically have high installation costs that are more difficult to justify based solely on the energy savings associated with the improvement. Despite the long paybacks, these ECMs in many cases provide valuable and much needed infrastructure improvements for the facility. These ECMs include boiler upgrades, HVAC equipment upgrades, etc. It should also be noted that projects under a 15 year payback should be reviewed in the event the District wishes to move forward with an Energy Savings Improvement Program where these projects could be included that program.

• ECM #1: Solar Thermal Domestic Hot Water

Electric Heat is an inefficient way to heat domestic hot water inherently due to the higher cost per Btu of heat produced. Much of the building is heated with electric hot water heaters located in isolated areas from a natural gas line or the ability to be properly vented. Due to this fact Solar Thermal is recommended to help supplement the need to operate the electric hot water heaters.

• ECM #2: Electric VAV to Hot Water VAV with New Condensing Boilers Electric Heat is an inefficient way to heat a building inherently due to the higher cost per Btu of heat produced. In this ECM the replacement of electric reheat in the VAV boxes to hot water heat produced by gas fired boilers would provide a much more cost effective alternative to heating. This measure also requires installation of condensing boilers that can provide a heating efficiency ranging from 85% to 99%. While very efficient these boilers are costly to implement. It is recommended the District review this ECM for future implementation when the equipment has reached the end of its useful life or the building is being renovated. Combined Project Approach: Although only 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 provide 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 ECMs provides Little Egg Harbor Township School District with the opportunity to implement a large portion of the ECMs identified within George J. Mitchell Elementary School. The program financing allows for the implementation with no upfront cost to the District. Implementation of an ESIP provides significant benefits and should be strongly considered by the District.



Renewable Energy Measures:

The Mitchell School is an excellent candidate for the installation of additional photovoltaic arrays. Given the school has electric heat the installation of solar electric generation could significantly reduce the grid electricity purchased by the school. Parking lot solar canopies should be considered in the front and side parking lots of the school; due to the limited available roof space (Further detail is provided in Appendix F). Considering the long payback period for the installation of a solar system utilizing self financing, bonding, or capital dollars it is recommended the District consider alternative financing approaches, such as a Power Purchase Agreement (or PPA). The PPA would require the District to put little to no upfront out of pocket dollars in order to install and maintain the system, the only requirement of the district would be to purchase the power generated at an agreed upon rate to be below their existing utility rate. CEG recommends the Owner review all alternative funding options before deciding to not implement this renewable energy measure.

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 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:

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 entrance 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. Educate staff and students on awareness of wasteful energy practices such as leaving lights

on unnecessarily, leaving on of non-essential computer and/or equipment at the end of the day, leaving of outside doors/windows open as a means to control room temperature, etc.

Overall, the George J. Mitchell Elementary School appears to be operating at a high efficiency level compared to other schools in the region. With the implementation of the above recommended measures the Little Egg Harbor School District will realize further energy savings at the George J. Mitchell Elementary School.



II. INTRODUCTION

The comprehensive energy audit covers the 106,374 square foot George Mitchell Elementary School, which includes the following spaces: Auditorium, cafeteria, classrooms, offices, and gymnasium. Electrical and natural gas utility information is 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 is 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

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. If multiple ECM’s are recommended to be implemented, the combined savings is calculated and identified appropriately. 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 base 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:

IV. HISTORIC ENERGY CONSUMPTION/COST A. Energy Usage / Tariffs 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. The electric usage profile represents the actual electrical usage for the facility. Atlantic City (ACE) provides electricity to four meters at the facility under their Monthly General Service rate for three meters and Annual General Service for one meter. The school has contracted South Jersey Energy, a Third Party Supplier (TPS), to provide electric commodity supply (generation) service. 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 gas usage profile shows the actual natural gas energy usage for the facility. New Jersey Natural Gas provides natural gas to the facility under the General Service - Large (GSL) rate structure. The school has contracted Pepco Energy Service, a Third Party Supplier (TPS), to provide gas commodity supply (generation) service. 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 overall cost for utilities is calculated by dividing the total cost by the total usage. Based on the utility history provided, the average cost for utilities at this facility is as follows: Description Average

Electricity 14.2¢ / kWh Natural Gas $1.27 / Therm

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:

Figure 3 Source Energy Use Intensity Distributions: Elementary Schools

It should be noted that while the School produces “Zero Emission” or “Green/Renewable Energy” through its on site solar system, the selling/trading of the Solar Renewable Energy Certificates (SREC) by the district transfers ownership rights of the “Green or Zero Emission” characteristics of this energy to the purchaser of the SREC. While the school still utilizes the electricity produced by the system, it is unable to take credit for the renewable properties of this energy such as emissions reductions or source energy credit. Therefore the Source Energy Use Intensity for the electricity generated by the solar system is the same as that purchased from the grid.

SOURCE EUI = 172.0



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.

V. FACILITY DESCRIPTION

The 106,374 SF George J. Mitchell Elementary School is a one story facility comprised of classrooms, gymnasium, cafeteria, kitchen, administrative offices, corridors, bathrooms and mechanical rooms.

The total number of occupants at the George Mitchell Elementary School building is approximately 1,156 including students, teachers and the custodial staff. The facility is open between the hours of 6:45 AM and 6:00 PM for school hours, before-school and afterschool programs. Custodial services usually take place between the hours of 3:30 PM and 11:30 PM. The facility is closed on weekends. A portion of the facility remains open during summer months for various social programs and cleaning in the building. Actual occupancy use is minimal. However, the owner keeps the building at design temperature to control the temperature and humidity for staff and the programs that are occurring at the facility during the summer months.

Exterior walls are 4” brick veneer with 8” CMU construction. There is a 1 ¾ inch air space and 1 inch rigid insulation in all exterior walls. The windows throughout the facility are in good condition and appear to be maintained. Typical windows throughout the facility are 1” insulated low-E, tinted and tempered glass with aluminum frames. Roll down shades are utilized through the facility for occupant comfort. The shades are valuable because they help to reduce heat loss in the winter and reduce solar heat gain in the summer. The majority of the roof is sloped with shingles but a portion of the roof is constructed of a flat EPDM (ethylene propylene diene monomer) rubber style roof where most of the HVAC equipment was located. The insulation below the roof consists of ½ inch recovery board and rigid insulation as well as batt insulation above the ceiling. The original building was built in 1951. Renovations to the building occurred in 1959, 1964, 1976, 1999 and 2009.

HVAC Systems

Packaged rooftop units (RTU) 1, 2 and 3 serve area A, B and the middle region of the school. There are two (2) Trane models YCH360 and YCH480 with a nominal cooling capacity of 30 and 40 tons with heating capacities of 350 and 400 MBH. These RTU’s are variable air volume (VAV) units with step control, modulating gas heat, static pressure sensor in the duct, unit mounted control supply fan VFD, full economizer with exhaust fans, and heat recovery. In addition these units are equipped with demand ventilation control (DVC). They are three (3) years old, in good condition and have 12 years until they are past their expected ASHRAE useful service life.

Packaged rooftop units (RTU) 4 and 5 serve the cafeteria. These units are Aaon model RM-013 with nominal cooling capacity of 13 tons and heating capacities of 180 MBH. These RTU’s are constant volume units with enthalpy economizers with motorized relief, outside air dampers, CO2 sensors, and 2-stage cooling. Outside air dampers are controlled by CO2 sensors from 0% to minimum outside air. Additionally, these units have hot gas reheat dehumidification, modulating gas heat and demand ventilation control (DVC) options. They are three (3) years old, in good condition and have 12 years until they are past their expected ASHRAE useful service life.



Packaged rooftop unit (RTU) 6 serves the gymnasium, RTU 7 serves the library and RTU 8 serves area D. Rooftop unit 6 is Aaon model RM-020, RTU 7 is Aaon model RM-010 and rooftop 8 is Trane model YCH-600, with nominal cooling capacities of 20, 10 and 50 tons and heating capacities of 270, 350 and 400 MBH, respectively. These RTU’s are constant volume units with enthalpy economizers with motorized relief, outside air dampers, CO2 sensors, and 2-stage cooling. Outside air dampers are controlled by CO2 sensors from 0% to minimum outside air. Additionally, these units have hot gas reheat dehumidification, modulating gas heat and demand ventilation control (DVC) options. They are three (3) years old, in good condition and have 12 years until they are past their expected ASHRAE useful service life.

Packaged rooftop unit (RTU) 9 serves the new addition to the school. There is one (1) Aaon model RN-060 with a nominal cooling capacity of 60 tons and with a heating capacity of 540 MBH. This RTU is a variable air volume (VAV) unit with step control, modulating gas heat, static pressure sensor in the duct, unit mounted control supply fan VFD, full economizer with exhaust fans, and heat recovery. In addition this unit is equipped with demand ventilation control (DVC). The unit is three (3) years old, in good condition and has 12 years until it is past the expected ASHRAE useful service life.

There are several low capacity split systems which serve computer room, kitchen, original building offices and library. These split systems have a capacity range from 1 to 5 tons. Manufacturers include Daikin, Carrier and Fujitsu.

The new addition that was built in 2007 gained two (2) Aerco Modulex boilers with an input capacity of 418 MBH and an output capacity of 390 MBH. These boilers have a high efficiency of approximately 93% and are capable of modulating to satisfy varying loads. The new wing utilizes these boilers in combination with a direct expansion Aaon rooftop unit with gas heating. The rooftop provides enough heat to maintain a certain designated temperature, then the hot water variable air volume boxes will condition the preheated air from the rooftop to the designated room setpoint.

The original building contains two (2) Weil McLain boilers model CGA-7 with an input capacity of 210 MBH and an output capacity of 175 MBH. These units were installed during the 1999 renovation and they currently serve the baseboard heat for the original building. During the survey, CEG was advised that these boilers have been turned off and are not in use. Rooftop units with gas heat completely condition all areas of the existing building, coupled with VAV’s with electric reheat. The electric VAV’s are an inefficient way to heat the system and consume a large amount of electricity, resulting in high electric bills which George J. Mitchell is currently observing.

Exhaust System

The exhaust for the offices, classrooms, bathrooms and the corridors is provided by roof exhausters and integral exhaust fans within the rooftop units. The exhaust fans operate based on the facility occupancy schedule.



The kitchen includes one (1) large commercial exhaust hood, which provides exhaust for the cooking appliances. The hood is 4ft x 14ft and operates at constant speed between 5 AM and 2 PM. The hood is manually controlled with wall switches.

HVAC System Controls

The entire George J. Mitchell Elementary School is controlled by a central DDC (Direct Digital Control) system manufactured by TAC. The DDC system encompasses night set back, morning warm-up, temperature set-points and HVAC schedules.

Domestic Hot Water

Domestic hot water for the restrooms in the new wing is provided by one (1) 100 gallon, A.O. Smith gas fired hot water heaters, capacity of 199 MBH. The domestic hot water is circulated throughout the new addition by a hot water re-circ pump. The circulation pump is controlled by an aqua stat.

The original building is served by several domestic hot water systems located in different sections of the building. In total there are thirteen (13) other domestic hot water heaters within the building, eleven (11) of which are electric hot water heaters and serve the classroom sinks and bathrooms, and two (2) which are gas fired and serve main bathroom areas. For further information regarding the domestic hot water systems please refer to the Major Equipment List Appendix.

Lighting Typical lighting throughout building is fluorescent tube lay-in fixtures with T-8 lamps and electronic ballasts. The gymnasium is equipped with HID light fixtures. There are additional areas within the elementary school which contain T-12 lamps and magnetic ballasts which are scattered randomly. Photovoltaic System The school currently houses a 28 kilowatt rooftop solar array overtop the Cafetorium. The system is comprised of 160 Solar World SW 175 panels rated at 175 watts each. The system has been installed and operating since December 2009 and can produce approximately 35,000 kilowatt-hours annually.

VII. ENERGY CONSERVATION MEASURES ECM #1: Solar Domestic Hot Water System Description: George J. Mitchell Elementary School operates with a nearly year round demand for hot water production. The hot water is supplied by large electric water heaters in certain areas of the school. Electricity is one of the most expensive sources of domestic hot water production. Therefore, installation of a solar thermal hot water heating system is an economical option for offsetting the electricity usage and demand for this facility. This ECM includes the installation of a solar thermal system to produce domestic hot water. The system includes solar thermal panels mounted over the roof of the A wing which serves offices and classrooms and B wing near the existing hot water heaters located in classroom closet areas between two rooms. This installation also includes piping distribution to the domestic hot water tanks, a pre-heat hot water heat exchanger and pumps for glycol distribution, and controls. The system features a pre-heat tank with the existing tanks still in place as a back-up means for hot water production to ensure no loss of hot water production. The calculations are based on Viesmann Flat Plat collectors model VITOSOL 200F or equivalent. It is recommended the owner retain a professional engineer to confirm equipment sizing and finalize design as well as the structural integrity of the existing structure to support the installation of the new panels Energy Savings Calculations: Existing Domestic Hot Water Parameters: Avg. Electricity Cost = $0.142/kWh Existing Domestic Water Heating Efficiency = 100% Estimated monthly domestic HW usage* = 4,241 kWh * Equals to 4% of total energy usage of the facility based on U.S. Energy Information Administration - EIA, Commercial Buildings Energy Consumption Survey, CBECs Solar Thermal System Parameters: See the Solar Domestic Hot Water Heater Appendix for detailed calculations.

ECM #2: Replace Electric VAV with Hot Water VAV Description: The George J. Mitchell Elementary School’s core building uses a packaged rooftop system with gas heat in conjunction with VAV (Variable Air Volume) devices equipped with electric reheat. This form of heating is very expensive due to the high cost of electricity. The use of hot water reheat VAV’s would help alleviate some of the electrical consumption for the facility. In order to implement this ECM, a new hot water heating system needs to be installed. The existing boilers are currently not in operation due to the rooftop packaged unit’s ability to satisfy the load sufficiently without supplementary conditioning. Additionally, there is no hot water piping in the area above the ceiling where the hot water VAV’s would be located. With the installation of new condensing hot water boilers which have efficiencies as high as 96%, the new system will operate at almost the same efficiency as the last but will cost less due to the use of natural gas which is much cheaper than electric. This ECM includes the installation of two (2) Aerco modulating boilers model MLX 757, forty-nine (49) hot water VAV boxes and a new piping system for connecting the new boilers with the VAV boxes. This ECM also includes the decommissioning of the two (2) existing Weil McLain boilers as well as the electric VAV’s currently in use. Energy Savings Calculations: Savings Calculations were calculated with energy modeling software, Trane Trace 700 version 6.2.6.5, to compare the existing conditions to the alternative energy conservation measure. The model was built using existing information collected and provided by the school regarding lighting power density, occupancy profiles, HVAC information, and available floor plans.

ECM #3: Computer Monitor Replacement Description: The computers throughout the school utilize a mixture of CRT computer monitors and LCD computer monitors. Computers are located throughout the school and are becoming a larger and larger portion of a facility’s energy usage. The CRT computer monitors are outdated and have several disadvantages such as; significantly increased higher energy consumption, uses large amount of desk space, poor picture quality, distortions and flickering image, secular glare problems, and high weight, and electromagnetic emissions. Many of these drawbacks are difficult to quantify except for the energy use. CRT monitors use considerably more energy than an alternative flat panel LCD monitor. Replacement of the existing CRT monitors with LCD monitors saves considerable energy as well as provides other ergonomic benefits. Based on the site survey it was noted that there are 50 LCD monitor and 161 CRT monitors. Some of the monitors were left in screen saver mode, which is deceiving since this mode only saves the computer screen from image burn in, however it does not save on energy consumption. The average operating hours for all computers and monitors is estimated based on the site survey observations. Energy consumption of computer monitors is based on averages for power usage of various computer monitors. This ECM includes replacement of all existing CRT monitors with LCD flat panel monitors throughout the facility. Installation costs were neglected for this ECM with the intention that this ECM would be replaced by the township. The calculations are based on the following operating assumptions: Energy Savings Calculations: No. of CRT Monitors: 161 Operating Weeks per Yr: 36 Hrs per Week: 50 (10 hrs per day estimated average)

ECM #4: Demand Controlled Ventilation in Gym & Cafeteria Description: Demand Controlled Ventilation (DCV) is a means to provide active, zone level control of ventilation for spaces within a facility. The basic premise behind DCV is monitoring indoor CO2 levels versus outdoor CO2 levels in order to provide proper ventilation to the spaces within the facility as well as saving costly dollars treating unconditioned ventilation air. Carbon dioxide ventilation control or demand controlled ventilation (DCV) allows for the measurement and control of outside air ventilation levels to a target cfm/person ventilation rate in the space (i.e., 15 cfm/person) based on the number of people in the space. It is a direct measure of ventilation effectiveness and is a method whereby buildings can regain active and automatic zone level ventilation control, without having to open windows. The fixed ventilation approach depends on a set-it-and-forget-it methodology that is completely unresponsive to changes in the way spaces are utilized/occupied or how equipment is maintained. A DCV system utilizes various control algorithms to maintain a base ventilation rate. The system monitors space CO2 levels and the algorithm automatically adjusts the outdoor and return air dampers to provide the quantity of outdoor air to maintain the required CO2 level in the space. System designs are normally designed for maximum occupancy and the ventilation rates are designed for this (maximum) occupancy. In areas where occupancy swings are prevalent there is ample opportunity to reduce outdoor air quantity to satisfy the needs of the actual number of occupants present. By initiating the active controls for the DCV system, energy savings are realized by the reduced quantities of outdoor air that do not require heating and cooling energy from the steam and chilled water plants. RTU-4 and RTU-5 together condition the cafeteria while RTU-6 conditions the gymnasium. There is already a demand control ventilation system installed for all of these units with CO2 sensors in the return air duct, modulating control of exhaust air fans with a VFD and a mode enable sensor option for the supply, return and outside air. From information gathered from the building manager and observations of the controls for these units, it is assumed that the demand control ventilation option is not on an active setting; therefore the possible savings with the current system can be optimized with further investigation into the controls for these areas. It is assumed that these units are only utilizing the CO2 sensors as monitoring devices and not actively controlling the system. This ECM will encompass a visit from a controls vendor which will assess the system and enable the active controls for these air handling units demand control ventilation system. This system allows the air handling units to respond to changes in occupancy and therefore reduce the amount of outside air that has to be conditioned. Outside air accounts for a large portion of the energy consumption in the HVAC system, especially in high occupancy spaces. 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:



• Demand Control Ventilation 10% - 15%.

Energy savings achieved through “Demand Control Ventilation” average 10%-15%. Savings resulting from the implementation of this ECM for energy management controls are approximately 4% of the total HVAC energy cost for this system. The only component included is software programming. Cost of programming = 20 Hours x $150/Hr = $3,000 Energy Savings Calculations: Savings Calculations were calculated with energy modeling software, Trane Trace 700 version 6.2.6.5, to compare the existing conditions to the alternative energy conservation measure. The model was built using existing information collected and provided by the school regarding lighting power density, occupancy profiles, HVAC information, and available floor plans.

ECM #5: HVAC Scheduling Adjustments Description: Typical HVAC operation hours for the George J. Mitchell Elementary School are between 5:00 AM to 7:00 PM Monday through Friday. Cleaning and maintenance for the building is typically take care of during the weekdays at night between 7:00 PM and 11:00 PM. There is no weekend operation. It was observed through the building survey, which included a review of the controls setup for the building, that the temperature set-points and setbacks for the school may not have been running at the most optimal setting. In looking through some of the settings, it was noted that the building was running on the following schedule: Heating Season Monday-Friday (5:00 AM – 7 PM) = approximately 70°F on average Monday-Friday (7:00 PM – 5:00 AM) = setback to a range of 61°F-63°F Weekends = setback to a range of 61°F-63°F Cooling Season Monday-Friday (5:00 AM – 7 PM) = 71°F Global set-point Monday-Friday (7:00 PM – 5:00 AM) = 81°F setback Weekends = 81°F setback CEG recommends setting the DDC system setpoints more conservatively for a system of this type. This ECM will utilize the ASHRAE 55 Standard for Thermal Comfort in choosing temperature set-points. The recommended DDC set points for heating/cooling in the spaces are as follows: Heating Season Monday-Friday (5:00 AM – 7 PM) = 70°F Monday-Friday (7:00 PM – 5:00 AM) = 65°F Weekends = 65°F Cooling Season Monday-Friday (5:00 AM – 7 PM) = 75°F Global set-point Monday-Friday (7:00 PM – 5:00 AM) = 80°F setback Weekends = 80°F setback Due to the fact that a control scheme is already in place for this building, minor adjustments to the system have the possibility of showing savings for a low cost output up-front. In addition, further savings could be realized by limiting the “Hours of Operation” and reducing the time that the HVAC system is set in an occupied mode.



Energy Savings Calculations: Savings Calculations were calculated with energy modeling software, Trane Trace 700 version 6.2.6.5, to compare the existing conditions to the alternative energy conservation measure.

ECM #6: Occupancy Controlled Power Strips Description: Plug loads in buildings are increasingly becoming a majority share of electrical consumption annually, as HVAC and lighting technologies are becoming more efficient and more energy is being utilized by other equipment. The Elementary School computer lab has approximately thirty computers used by students. During the survey it was noted that many of these computers were on and operating while no one was using the work station. To reduce idle power draw load from the computer and peripheral equipment while not in use, CEG recommends the installation of Watt Stopper IDP-3050 occupancy controlled power strip. The power strip has the same features of a typical strip except it is fitted with an infrared occupancy sensor. The sensor reads when an occupant is using their workstation and insures all equipment is fully powered, however when an occupant is not present the strip shuts power off to devices plugged into the control outlets of the strip. Installing these power strips could substantially reduce energy waste due to plugged in equipment. The intent of this ECM is to provide control of ancillary devices such as computer monitors, speakers, printers, phone charges, task lights, and etc. that can be shut off by the control outlets when the user is not present. Energy Savings Calculations: The manufacturer has estimated that typical savings for their power strip can save 75 kilowatt-hours per work station or more.

ECM #7: Lighting Upgrade – Retrofits and Re-lamping Description: The majority of the lighting throughout the George J. Mitchell Elementary School building is provided with fluorescent fixtures with older generation, 700 series 32W T8 lamps and electronic ballasts. Although 700 series T8 lamps are considered fairly efficient, further energy savings can be achieved by replacing the existing T8 lamps with new generation, 800 series 28W T8 lamps without compromising light output. CEG recommends, re-lamping all of the fixtures with 28W T8 lamps. In addition, some of the storage areas, locker room and gym areas, offices, auditorium, classrooms, restrooms and kitchen areas still have a variety of older fixtures with T12 lamps with magnetic ballasts, incandescent lamps and incandescent exit signs. It is recommended to retrofit or replace all of the T12 fixtures and the incandescent lights in these areas with high efficiency fluorescent T8 fixtures with electronic ballasts or compact fluorescent lamps. This ECM includes re-lamping of the existing fluorescent fixtures with 800 series, 28W T8 lamps. The ECM also includes retrofit of all T12 fixtures with T8 fixtures with electronic ballasts in the building. The new, energy efficient T8 fixtures will provide adequate lighting and will save on electrical costs due to better performance of the lamp and ballasts. This ECM also includes maintenance savings through the reduced number of lamps replaced per year. The expected lamp life of a T8 lamp is approximately 30,000 burn-hours, in comparison to the existing T12 lamps which is approximately 20,000 burn-hours. The facility will need approximately 33% less lamps replaced per year for each one for one fixture replaced. The ECM also includes replacement of any incandescent lamps with compact fluorescent lamps. Compact fluorescent lamps (CFL’s) were designed to be direct replacements for the standard incandescent lamps which are common to table lamps, spot lights, hi-hats, bathroom vanity lighting, etc. The light output of the CFL has been designed to resemble the incandescent lamp. The color rendering index (CRI) of the CFL is much higher than standard fluorescent lighting, and therefore provides a much “truer” light. The CFL is available in a myriad of shapes and sizes depending on the specific application. Typical replacements are: a 13-Watt CFL for a 60-Watt incandescent lamp, an 18-Watt CFL for a 75-Watt incandescent lamp, and a 26-Watt CFL for a 100-Watt incandescent lamp. The CFL is also available for a number of “brightness colors” that is indicated by the Kelvin rating. A 2700K CFL is the “warmest” color available and is closest in color to the incandescent lamp. CFL’s are also available in 3000K, 3500K, and 4100K. The 4100K would be the “brightest” or “coolest” output. A CFL can be chosen to screw right into your existing fixtures, or hardwired into your existing fixtures. Where the existing fixture is controlled by a dimmer switch, the CFL bulb must be compatible with a dimmer switch. In some locations the bulb replacement will need to be tested to make sure the larger base of the CFL will fit into the existing fixture. The energy usage of an incandescent compared to a compact fluorescent approximately 3 to 4 times greater. In addition to the energy savings, compact fluorescent fixtures burn-hours are 8 to 15 times longer than incandescent fixtures ranging from 6,000 to 15,000 burn-hours compared to incandescent fixtures ranging from 750 to 1000 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.

ECM #8: Lighting Controls Upgrade – Occupancy Sensors Description: Some of the lights in the school building are left on unnecessarily. In many cases the lights are left on because of the inconvenience to manually switch lights off when a room is left or on when a room is first occupied. This is common in rooms that are occupied for only short periods and only a few times per day. In some instances lights are left on due to the misconception that it is better to keep the lights on rather than to continuously switch lights on and off. Although increased switching reduces lamp life, the energy savings outweigh the lamp replacement costs. The payback timeframe for when to turn the lights off is approximately two minutes. If the lights are expected to be off for at least a two minute interval, then it pays to shut them off.

Lighting controls come in many forms. Sometimes an additional switch is adequate to provide reduced lighting levels when full light output is not needed. Occupancy sensors detect motion and will switch the lights on when the room is occupied. Occupancy sensors can either be mounted in place of a current wall switch, or on the ceiling to cover large areas. The U.S. Department of Energy sponsored a study to analyze energy savings achieved through various types of building system controls. The referenced savings is based on the “Advanced Sensors and Controls for Building Applications: Market Assessment and Potential R&D Pathways,” document posted for public use April 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 10% of the total light energy controlled by occupancy sensors and daylight sensors (The majority of the savings is expected to be after school hours when rooms are left with lights on) This ECM includes installation of ceiling type sensors for individual offices, classrooms, large bathrooms, and libraries. Sensors shall be manufactured by Sensorswitch, Watt Stopper or equivalent. The Investment Grade Lighting Audit Appendix of this report includes the summary of lighting controls implemented in this ECM and outlines the proposed controls, costs, savings, and payback periods.

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. CEG has assessed the feasibility of installing renewable energy measures (REM) for the George Mitchell Elementary School in Little Egg Harbor Township utilizing renewable technologies and concluded that there is potential for solar energy generation. The solar photovoltaic system calculation summary will be concluded as REM#1 within this report. Solar Generation Solar energy produces clean energy and reduces a building’s carbon footprint. This is accomplished via photovoltaic panels which mounted generally in a southerly facing exposure. Flat roof, as well as sloped areas can be utilized; flat areas will have the panels turned to an optimum solar absorbing angle. Parking lots can also be utilized for the installation of a solar array. A truss system can be installed that is high enough to park vehicles under the array and no parking lot area is lost. 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 $350, this value was used in our financial calculations. This equates to $0.35 per kWh generated. The Mitchell School already has a roof mounted solar system sized at 28 kilowatts, after further review of available roof space CEG believes that due to the large amount of equipment on the remaining areas of the roof that a ground mounted parking lot canopy system would be much more advantageous for the school to pursue. An area of 19,556 S.F. can be utilized for a PV system as depicted in the Renewable / Distributed Energy Measures Calculation Appendix. Using this square footage it was determined that a system size of 305.9 kilowatts could be installed. A system of this size has an estimated kilowatt hour production of 335,093 KWh annually, reducing the overall utility bill by approximately 26.34% percent. A detailed financial analysis can be found in the Renewable / Distributed Energy Measures Calculation Appendix. This analysis illustrates the payback of the system over a 25 year period. The eventual degradation of the solar panels and the price of accumulated SREC’s are factored into the payback. The proposed photovoltaic array layout is designed based on the specifications for the Sun Power SPR-230 panel. This panel has a “DC” rated full load output of 230 watts, and has a total panel conversion efficiency of 18%. Although panels rated at higher wattages are available through Sun Power and other various manufacturers, in general most manufacturers who produce



commercially available solar panels produce a similar panel in the 200 to 250 watt range. This provides more manufacturer options to the public entity if they wish to pursue the proposed solar recommendation without losing significant system capacity. The array system capacity was sized on available parking lot space at the existing facility and existing electric load limitation. Estimated solar array generation was then calculated based on the National Renewable Energy Laboratory PVWatts Version 1.0 Calculator. In order to calculate the array generation an appropriate location with solar data on file must be selected. In addition the system DC rated kilowatt (kW) capacity must be inputted, a DC to AC de-rate factor, panel tilt angle, and array azimuth angle. The DC to AC de-rate factor is based on the panel nameplate DC rating, inverter and transformer efficiencies (95%), mismatch factor (98%), diodes and connections (100%), dc and ac wiring(98%, 99%), soiling, (95%), system availability (95%), shading (if applicable), and age(new/100%). The overall DC to AC de-rate factor has been calculated at an overall rating of 77%. The PVWatts Calculator program then calculates estimated system generation based on average monthly solar irradiance and user provided inputs. The monthly energy generation and offset electric costs from the PVWatts calculator is shown in the Renewable/Distributed Energy Measures Calculation Appendix. The proposed solar array is qualified by the New Jersey Board of Public Utilities Net Metering Guidelines as a Class I Renewable Energy Source. These guidelines allow onsite customer generation using renewable energy sources such as solar and wind with a capacity of 2 megawatts (MW) or less. This limits a customer system design capacity to being a net user and not a net generator of electricity on an annual basis. Although these guidelines state that if a customer does net generate (produce more electricity than they use), the customer will be credited those kilowatt-hours generated to be carried over for future usage on a month to month basis. Then, on an annual basis if the customer is a net generator the customer will then be compensated by the utility the average annual PJM Grid LMP price per kilowatt-hour for the over generation. Due to the aforementioned legislation, the customer is at limited risk if they generate more than they use at times throughout the year. With the inefficiency of today’s energy storage systems, such as batteries, the added cost of storage systems is not warranted and was not considered in the proposed design. Direct purchase involves the school paying for 100% of the total project cost upfront via one of the methods noted in the Installation Funding Options section below. Calculations include a utility inflation rate as well as the degradation of the solar panels over time. Based on our calculations the following is the payback period:

*The solar energy measure is shown for reference in the executive summary Renewable Energy Measure (REM) table



Given the large amount of capital required by the school to invest in a solar system through a Direct Purchase CEG does not recommend the school pursue this route. It would be more advantageous for the school to solicit Power Purchase Agreement (PPA) Providers who will own, operate, and maintain the system for a period of 15 years. During this time the PPA Provider would sell all of the electric generated by the Solar Arrays to the school at a reduced rate compared to their existing electric rate. CEG has performed a preliminary analysis that shows the potential benefits to the school in reduce electric pricing over the life of the agreement. It is estimated that the school could potentially see a reduction in electric rate from 5% to 15% and thus the analysis performed shows three alternative pricing elements based on a 1 cent, 1.5 cent, and 2 cent rate reduction. The following table shows the potential year 1 electric cost savings for each of these alternative prices. Further detail is shown in the Renewable/Distributed Energy Measures Calculation Appendix of the cost benefit to the school over the life of the agreement.

POWER PURCHASE AGREEMENT SUMMARY

Wind Generation In addition to the Solar Analysis, CEG also conducted a review of the applicability of wind energy for the facility. Wind energy production is another option available through the Renewable Energy Incentive Program. 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 usage. Based on CEG’s review of the applicability of wind energy for the facility, it was determined that the while average wind speed is adequate to support commercial size wind turbines the site space available is very limited. Therefore CEG does not recommend wind generation.



IX. ENERGY PURCHASING AND PROCUREMENT STRATEGY Load Profile: Load Profile analysis was performed to determine the seasonal energy usage of the facility. Irregularities in the load profile will indicate potential problems within the facility. Consequently based on the profile a recommendation will be made to remedy the irregularity in energy usage. For this report, the facility’s energy consumption data was gathered in table format and plotted in graph form to create the load profile. Refer to The Electric and Natural Gas Usage Profiles included within this report to reference the respective electricity and natural gas usage load profiles. Electricity: The electricity usage profile demonstrates a steady year long load profile for facilities that have occupancy during the summer months. The average monthly usage for all accounts combined is 171,656 kWh with highest usage during June. The historical usage profile is beneficial and will allow for more competitive energy prices when shopping for alternative suppliers mainly due to the relatively flat load profile. Third Party Supplier (TPS) electric commodity contracts that offer’s a firm, fixed price for 100% of the facilities electric requirements and are lower than the Atlantic City Electric’s (AECO) BGS-FP default rate are recommended. Natural Gas: The Natural Gas Usage Profile demonstrates a very typical natural gas (heat load) profile. The summer months June through August have very little consumption. This load profile will yield less favorable natural gas pricing when shopping for alternative suppliers. This is because the higher winter month consumption will yield higher pricing which will not be offset by the summer month consumption. Nymex commodity pricing is generally higher in the winter months of November – March and lower in the summer months of April – October. Obtaining a flat load profile, (usage is similar each month), will yield optimum natural gas pricing when shopping for alternative suppliers. Third Party Supplier (TPS) natural gas commodity contracts that offer a product structure to include either 1) a fixed basis rate with a market based Nymex/commodity rate or 2) a fixed basis rate with fixed Nymex/commodity winter rate (Nov – March) and market based Nymex/commodity rate for the summer months (April – October) for 100% of the facilities metered natural gas requirements are both recommended due to current market pricing.



Tariff Analysis: Electricity: The facilities receive electrical service through Atlantic City Electric (AECO) on AGS-Sec (Annual General Service Secondary) and MGS (Monthly General Service). The facilities have contracted a Third Party Supplier (TPS) to provide electric commodity service. Current Third Party Supplier Terms and Conditions are unknown. For electric supply (generation) service, the client has a choice to either use AECO’s default service rate BGS-FP or contract with a Third Party Supplier (TPS) to supply electric. 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. 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, Atlantic City Electric 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. AECO’s delivery service rate includes the following charges: Customer Service Charge, Distribution Charge, Market Transition, Transition Bond Charge, Non Utility Generation Charge, Societal Benefits Charge (SBC), Infrastructure Investment Charge, System Control Charge, Regulatory Assets Recovery Charge, and Regional Greenhouse Gas Initiative Charge. Natural Gas: The school facilities currently receives natural gas distribution service through New Jersey Natural Gas (NJNG) on rate schedule GSL (General Service Large). The Frong Pond facility receive natural gas supply service (BGSS) through the utility, NJNG, and the GJ Mitchell facility receives Third Party natural gas supply service. Current Third Party Supplier Terms and Conditions are unknown. For natural gas supply service, the client has a choice to either use NJNG’s default service rate BGSS or contract with a Third Party Supplier (TPS) to supply natural gas. NJNG provides basic gas supply service (BGSS) to customers who choose not to shop from a Third Party Supplier (TPS) for natural gas commodity. The option is essential to protect the



reliability of service to consumers as well as protecting consumers if a third party supplier defaults or fails to provide commodity service. Please refer to the links below for a recap of monthly natural gas BGSS charges from NJNG. https://www.njng.com/pdf/Mar2011LargeCommercialPriceTable.pdf The utility, NJNG is responsible for maintaining the existing network of underground pipes that make up the delivery system, which will serve all consumers, regardless of whom they choose to purchase their natural gas from. NJNG’s delivery service rates include the following charges: Customer Service Charge, Delivery Charge, and Balancing Charges.

Electric and Natural Gas Commodities Market Overview:

Current electricity and natural gas market pricing has remained relatively stable over the last year. Commodity pricing in 2008 marked historical highs in both natural gas and electricity commodity. Commodity pricing commencing spring of 2009 continuing through 2011, 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 (3/08/2011):

U.S. Natural Gas Prices. The Henry Hub spot price averaged $4.09 per MMBtu in February 2011, $0.40 per MMBtu less than the average spot price in January 2011. EIA expects that the Henry Hub spot price will average $4.10 per MMBtu in 2011, a drop of $0.29 per MMBtu from the 2010 average. EIA expects the natural gas market to begin to tighten in 2012, with the Henry Hub spot price increasing to an average of $4.58 per MMBtu.

Uncertainty over future natural gas prices is slightly lower this year compared with last year at this time. Natural gas futures for May 2011 delivery (for the 5-day period ending March 3) averaged $3.98 per MMBtu, and the average implied volatility over the same period was 33 percent. This produced lower and upper bounds for the 95-percent confidence interval for May 2011 contracts of $3.09 per MMBtu and $5.11 per MMBtu, respectively. At this time last year, the natural gas May 2010 futures contract averaged $4.77 per MMBtu and implied volatility averaged 39 percent. The corresponding lower and upper limits of the 95-percent confidence interval were $3.57 per MMBtu and $6.39 per MMBtu.

U.S. Electricity Retail Prices. During 2010, retail prices for electricity distributed to the residential sector averaged 11.58 cents per kilowatthour, about the same level as in 2009. EIA expects residential prices to rise by 1.0 percent in 2011, followed by an increase of 0.5 percent in 2012. The effect of lower generation fuel costs in 2011 should be more evident in retail prices for electricity distributed to the industrial sector, which EIA projects will fall 1.6 percent during 2011 and then rise 0.2 percent next year.



Pricing includes both utility distribution and energy commodity charges.



Recommendations:

1. CEG recommends an aggregated approach for 3rd party commodity supply procurement strategies for both electric and natural gas supply service. Aggregating the usage of all facilities for electricity and natural gas supply service, would allow the facilities to either continue to achieve or achieve a reduction in commodity supply costs. Energy commodities are among the most volatile of all commodities, however at this point and time, energy is extremely competitive and contract terms longer than 12 months are desirable. Contracts due to expire in the near term would continue to yield favorable pricing. It is important to aggregate usage where available and take advantage of these current market prices quickly, before energy increases. Overall, after review of the utility consumption, billing, and current commodity pricing outlook, CEG recommends that the facilities continue to participate in the energy supply aggregation group for electricity and explore options for utilizing an energy supply aggregation for natural gas for all facilities. Many aggregation groups utilize the advisement of a 3rd party unbiased Energy Consulting Firm experienced in the aggregation of and procurement of retail electricity and natural gas commodity. It is important to note that the Energy Consulting Firm should incorporate a rational, defensible strategy for purchasing commodity in volatile markets based upon the following:

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

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



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:

i. Energy Savings Improvement Program (ESIP) – Public Law 2009, Chapter 4

authorizes government entities to make energy related improvements to their facilities and par 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.

ii. 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.

iii. Power Purchase Agreement – Public Law 2008, Chapter 3 authorizes contractor

of up to fifteen (15) years for 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.

iv. 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%.

v. Energy Efficiency and Conservation Block Grants – The EECGB rebate provides

supplemental funding up to $20,000 for counties and local government entities to implement energy conservation measures. The EECGB funding is provided through the American Recovery and Reinvestment Act (ARRA). The local government must be among the eligible local government entities listed on the NJ Clean Energy website as follows - http://njcleanenergy.com/commercial-industrial/programs/eecbg-eligible-entities. This program is limited to municipalities and counties that have not already received grants directly through the US department of Energy.

This incentive is provided in addition to the other NJ Clean Energy program funding. This program’s incentive is considered the entity’s capital and therefore can be applied to the LGEA program’s requirements to implement the recommended energy conservation measures totaling at least 25% of the energy audit cost. Additional requirements of this program are as follows:



1. The entity must utilize additional funding through one or more of the NJ Clean Energy programs such as Smart Start, Direct Install, and Pay for Performance.

2. The EECBG funding in combination with other NJ Clean Energy programs may not exceed the total cost of the energy conservation measures being implemented.

3. Envelope measures are applicable only if recommended by the LGEA energy audit and if the energy audit was completed within the past 12 months.

4. New construction and previously installed measures are not eligible for the EECBG rebate.

5. Energy conservation measures eligible for the EECBG must fall within the list of approved energy conservation measures. The complete list of eligible measures and other program requirements are included in the “EECBG Complete Application Package.” The application package is available on the NJ Clean Energy website - http://njcleanenergy.com/commercial-industrial/programs/energy-efficiency-and-conservation-block-grants.

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.



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

F. Educate staff and students on awareness of wasteful energy practices such as leaving lights on unnecessarily, leaving on of non-essential computer and/or equipment at the end of the day, leaving of outside doors/windows open as a means to control room temperature, etc.



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.

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.
