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. The following Energy Conservation Measures are recommended for the facility. See below for the recommended ECM summaries:

• ECM #1: Computer Monitor Replacement

• ECM #3: Install Pump VFD’s

• ECM #5: Lighting Upgrade

• ECM #6: Lighting Occupancy Sensors & Daylight Sensors

• ECM #7: Melink Kitchen Exhaust Controls

ECM #1 – Computer Monitor Replacement:

Cathode Ray Tube (CRT) monitors are used throughout the school district. These monitors use approximately three times more energy than a new flat panel LCD monitor. Since the majority of all computer monitors were noted to be on and in screen saver mode, it was determined that the hours of operation for this plug in load are almost continuous. The energy savings from replacing the existing CRT monitors with LCD monitors will pay for the new monitors in approximately two years saving $9,488 annually. It is important to realize that these savings are comparing the energy savings based on the existing operating hours both before and after the retrofit, however even further savings could be seen if computers and monitors were turned off for all hours they are not in use. See the additional recommendations below.

ECM #4 – Install Pump VFD’s:

VFDs allow HVAC system pumps to operate at reduced speeds when the call for heating is below the peak. The hours of operation that the building load is below peak are considerable, which reduces pump energy for the majority of the time. The High School includes large boiler water pumps that can take advantage of this control. This ECM also includes the replacement of the existing motors with premium efficiency motors. The savings as a result of the reduction in pumping energy is approximately $16,484 annually, which has a simple pay back of 4.5 years. This ECM is highly recommended for this facility.

ECM #6 – Lighting Upgrade:

The lighting upgrade potential at Overbrook High School consists of incandescent bulbs installed in the majority of the bathrooms, closets, and other misc. rooms throughout the school. The gymnasium utilizes old style metal halide fixtures. These fixtures have direct replacements that save considerable energy. The lighting retrofit includes compact fluorescent bulb replacements for the incandescent fixtures and new high bay T-5 high output fluorescent fixtures to replace the metal halide fixtures. Advantages include extended life, instant lamp start and superior light quality, making this ECM both financially beneficial and aesthetically / operationally beneficial.



This ECM has a simple payback of 2.0 years making it the fastest simple payback of all ECMs available.

ECM #6 – Lighting Occupancy Sensors / Daylight Sensors:

Lighting controls provide a simple and effective solution to the problem of lights being unnecessarily left on. Occupancy sensors provide a very fast payback since the installation costs are minimal per control device. Daylight Sensors provide valuable savings from daylight harvesting in addition to occupancy sensors. This ECM includes the installation of occupancy sensors for the remaining classrooms that do not already included occupancy sensors. This ECM also includes daylight sensors for entryways and hallways and stairwells with adequate natural light. The combination of both options has a simple payback of approximately 4.7 years and therefore is a valuable retrofit available for the school.

ECM #7 – Melink Kitchen Exhaust Controls

The commercial kitchen at Overbrook High School has a large potential to reduce energy use based on the constant volume operation of the kitchen exhaust from 6:00AM to 3:00PM. This ECM includes controls to allow the exhaust system to reduce its volume based on the actual use and requirement of the cooking equipment. This saves on exhaust fan energy as well as the energy needed to condition the heated air draw out of the kitchen. The energy savings for this commercial cooking facility is approximately $4,547 per year. The components needed to control the exhaust volume are sensors attached to the kitchen hoods and a variable frequency drive for the kitchen exhaust fan. The installation cost of this equipment and controls has a simple payback of 7.1 years. This ECM is another significant reduction in energy use and recommended for this facility.

REM #1 – Solar Photovoltaic System:

Solar photovoltaic systems have progressed over the years to become a realistic approach for many facilities. With the incentives and energy credits available today, solar PV system installation costs have dropped to provide paybacks less than 15 years such as this facility. Power purchase agreements provide another opportunity for facilities with limited funding to invest in a clean renewable source of energy. Based on the calculated estimate for the maximum roof area available for solar panels (15,000 SF), this facility could generate approximately 16% of their current electric use annually.

Additional Recommendations:

In addition to the ECMs, 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 in order to limit energy use from task lighting.

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 rooftop units are functioning properly to take advantage of free cooling and avoid excess outside air during occupied periods.

6. Seal openings around window unit penetrations to minimize outside air infiltration.

7. Turn off computer monitors and set computers to sleep when not being used. Computer monitors and computers are becoming one of the largest energy consumers in buildings today. Set computers to sleep when not being used and automatically turn off the computer monitors. Do not set computer monitors to “screen saver” mode which saves the screen life, not energy.

Overall, Overbrook High School’s energy use is above average when compared to other schools in the region; however this school is the least energy intensive building of all schools in the district with respect to total area. With the implementation of the recommended ECMs above, the BOE will see a significant step forward on the path of energy reduction.



II. INTRODUCTION

The comprehensive energy audit covers the 160,000 square foot High School, which includes: classrooms, offices, computer rooms, gymnasium, auditorium, cafeteria, kitchen, maintenance areas and storage areas. 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 Electric provides electricity to the facility under their Annual General Service Secondary rate structure. 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. South Jersey Gas Company provides natural gas to the facility under the General Service - Firm Transportation rate structure. 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:

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, CEG 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:

V. FACILITY DESCRIPTION

The 160,000 SF High School is a two story facility comprised of classrooms, offices, computer rooms, gymnasium, auditorium, cafeteria, kitchen, maintenance areas and storage areas. The building was built in 1969 with no additions added since the original construction. The school hours of operation are typical for a school; between 7:00AM and 2:30 PM. The gymnasium and auditorium are used after hours for sports and other events. The school is used very minimally in the summer. The school student enrollment is approximately 872 students and 80 teachers.

Building Envelope

The building exterior is comprised of block wall construction with face brick exterior for approximately 50% of the envelope. The remaining walls are made up of aluminum metal panel curtain wall system with approximately 25% windows. Insulation is minimal in the brick faced wall. The curtain wall system includes metal panels with dense fibrous insulation within the metal panels. The roof is a tar roof with approximately 2” rigid foam insulation below the membrane. The roof is topped with light and dark crushed stone. The windows throughout the facility are a combination of fixed pane windows and small operable windows for ventilation. The windows are single pane with clear glass. Overall the envelope for the building is in good condition.

HVAC Systems

The HVAC systems for the high school consist of a central heating plant and scattered AC systems for cooling of select areas of the building. The facility has undergone a slow phase out of window AC units with ductless split systems as window AC unit failures take place. Areas of the building that have air conditioning include: computer rooms, enclosed classrooms without windows, and some offices. The units range from new and great condition to old and poor condition. Most window AC units still in operation are approximately 1 - 1.5 tons in capacity.

The central heating system consists of two 16,737 MBH Cleaver Brooks fire tube boilers. The boilers were originally used to make steam, and since have been converted to hot water. One of the boilers has been retrofitted with new burner controls for improved firing and cycling. The boiler water is pumped throughout the building by two large constant volume 40 HP base mounted end suction pumps. The boiler loop water temperature is controlled based on an outside air temperature reset schedule by a 3-way mixing valve.

Air side systems include unit ventilators for the classrooms and large air handling units for the large spaces such as the gymnasium and auditorium. The unit ventilators and air handling units provide heat and ventilation. All portions of the heating system include pneumatic control valves and dampers. The boiler loop utilizes 3-way control valves on all terminal equipment and air handling units. Ventilation air is provided by outside air dampers at each unit.

Exhaust System

Air is exhausted from the building through the centrifugal roof exhausters. Exhaust is provided for toilet rooms, specialty rooms (such as art rooms, wood shop, chemistry rooms, and biology



rooms, etc.) and large assembly areas (such as the auditorium and gymnasium). The exhaust is manually controlled manually by the maintenance staff based on temperature and occupancy comfort. The toilet rooms exhaust fans are manually controlled by bath room wall switches. It was noted that some exhaust fans do not include dampers when fans are not running. The commercial kitchen includes two 20 foot by 4 foot commercial exhaust hoods. The hoods are utilized for heat and smoke exhaust over cooking ovens steamers, and a gas fired range. The kitchen hood is manually controlled by a wall switch and operates approximately 8 hrs per day.

HVAC System Controls

The cooling systems throughout the building utilize stand-alone local controls. Space temperature is controlled by dedicated thermostats wired to each AC unit. The majority of the cooling thermostats do not utilize programmability.

The heating system is controlled through pneumatic controls and a central control system. Air for the pneumatic system is provided by a central air tank and dual compressors. The air compressor appears to be recently replaced and in good condition. The air side equipment controls space temperature with 3-way control valves at each unit and a local thermostat. Unit ventilators are turned on and off based on the central control system schedule. Ventilation is provided by outside air dampers at each unit. The classrooms typically include a unit ventilator along with a relief air louver through the exterior wall. All dampers are controlled based on the central control system schedules. Outside air is introduced into the building during occupied periods. In unoccupied periods the outside air dampers close to limit conditioning of outside air.

Domestic Hot Water

Domestic hot water for the restrooms, kitchen, and various sinks throughout the school is provided by a large indirect style hot water tank located in the boiler room. Boiler water is used to heat the domestic hot water with an internal water to water heat exchanger. Since the boiler water is the sole source of domestic hot water heat, the boilers are required to run year round to provide domestic hot water. Boilers are shut down manually only when the building is unoccupied. The domestic hot water piping insulation appeared to be in fair condition. The kitchen dishwasher requires 160°F – 180°F domestic hot water. The domestic hot water temperature is boosted by an under-counter electric booster heater. The capacity information for the booster heater was not accessible.

Lighting & Internal Loads Typical lighting throughout building is fluorescent tube lay-in and pendant fixtures with T-8 lamps and electronic ballasts. Storage rooms and closets are lit with compact fluorescent lamps. The gymnasium is lit with high bay metal halide fixtures. The building exterior is lit with a combination of high pressure sodium lamps and metal halide lamps. The parking lot is lit with light poles and high pressure sodium lamps. All lighting throughout the building is controlled by a combination of manual switches and occupancy sensors. Entrance ways, hallways, stairwells, the gymnasium, and auditorium is manually control along with approximately 33% of the classrooms. Most offices, and private rooms including approximately 66% of the classrooms



utilize wall or ceiling mounted occupancy sensors. Outdoor lighting is controlled by photocells (dusk to dawn operation) for security needs. Many rooms throughout the building were noted to have high internal loads due to computers. The majority of the computer rooms throughout the building including the majority of private computers within the offices were left on. Approximately 90% of the computers had the either the computers on, or the computers and monitors on. The total quantity of personal desk top style computers in the building is approximately 212 PCs.

VII. ENERGY CONSERVATION MEASURES

ECM #1: Computer Monitor Replacement Description: The computers throughout the elementary school utilize CRT computer monitors. These computer monitors are used at almost every computer work station including the offices, computer labs, lounges, classrooms, etc. These 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 the 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 as well. Based on the site survey it was noted that a large number of the computers were left on and allowed to run 24 / 7. The majority 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 are based on manufacture’s specifications. This ECM includes replacement of all existing CRT monitors with LCD flat panel monitors throughout the school. Installation costs were neglected for this ECM with the intention that this ECM would be replaced by the school employees. The calculations are based on the following operating assumptions: Energy Savings Calculations: # of Computers: 212 Run Time %: 90% Weeks per Yr: 40 Hrs per Week: 168

ECM #1 - ENERGY SAVINGS SUMMARY



ECM #2: Condensing Boiler Installation Description: The existing boilers at Overbrook High School are large 4 pass steel fire tube boilers made by Cleaver Brooks. These boilers are used as the primary source of heat for the entire building. The boilers are original to the building and are over half of its life expectancy for typical fire tube boilers. The equipment appears to be maintained in fair operating condition. Even for boilers that are close to the end of its life it is difficult to predict the point at which the boiler becomes inoperable. With the increased efficiency of new condensing boilers, the savings through a replacement can be substantial. New condensing boilers could substantially improve the operating efficiency of the heating system of the building. Condensing boiler’s peak efficiency tops out at 99% depending on return water temperature. Due to the operating conditions of the building, the annual average operating efficiency of the proposed condensing boiler is expected to be 88%. The existing boiler’s efficiency is approximately 75%, which makes the condensing boilers an 13% increase in efficiency. This ECM is based on variable supply water temperature adjusted based on outdoor temperature. In addition to the space heating savings, the condensing boilers would provide an added benefit for the domestic hot water production. The existing domestic hot water is heated indirectly through a heat exchanger located in a large domestic hot water tank. The domestic hot water efficiency is equal to the boiler operating efficiency. The condensing boilers would provide hot water a increased efficiency. The domestic hot water efficiency would be improved by 13% for all hours in the heating season. In the non heating season the condensing boilers would be able to produce domestic hot water at approximately 95% efficiency since the operating boiler water temperature would be reduced dramatically compared to the heating season. This ECM includes installation of multiple condensing gas fired boilers to replace the existing fire tube boilers. The basis for this ECM is six Aerco Benchmark 3.0 Series Condensing boilers. The boiler installation is based on equal capacity of one of the existing fire-tube boilers. One additional condensing boiler is included in this ECM for redundancy.

ECM #3: Pump VFD Retrofit Description: The unit ventilators are utilizing a constant volume pumping design. The unit ventilators have 3-way control valves which allow continuous flow through the piping loop throughout the building. As a result the water loop pumps must provide full power output to circulate the water through all unit ventilators continuously. The 2-way control valves provide flow through the unit ventilators only when there is no call for heating or cooling, unlike 3-way control valves that allow constant flow of the water loop. 3-way control valves require full pumping energy continuously, while 2-way control valves allows the system to reduce flow when it is not needed. This measure includes capping off the bypass port on the 3-way control valves which effectively turns the valves into “2-way” control valves. When the unit ventilator is not calling for heating, the control valve closes reducing overall flow of the system. Variable frequency drives allow the pumps to slow down in response to a reduction in overall system flow. The reduction in operating flow allows the pumps to reduce energy consumption for all hours that the heating system is not at its peak load. This ECM includes the installation of Variable Frequency Drives on the two (2) existing 40 horsepower pumps in conjunction with piping modifications at each unit ventilator to cap off the bypass port on the 3-way control valves. The VFD’s would be controlled by a differential pressure sensor in the water loop to measure demand for water. The furthest unit ventilators from the loop pumps would remain as 3-way control valves (constant flow) to eliminate dead heading potential. This ECM also includes replacement of the existing pump motors with inverter duty motors that meet NEMA Premium Efficiency Standard, which also helps to reduce energy consumption. Energy and cost savings calculations are based on calculation software “PumpSave v4.2,” provided by ABB. The PumpSave calculation software is used to estimate the pumping energy for variable speed pump systems. The boiler water loop pump operation is estimated to be 4,380 Hrs per year since this system is used for about 6 months total. The pump flow, HD, and resultant energy are calculated based on the existing pump horse power installed.

ECM #4: AC Rooftop Units Replacement Description: The majority of the rooftop units at Overbrook High School are packaged split system direct expansion cooling units. Some of the existing rooftop units at the High school are old and in poor condition. The majority of the older units have been replaced with new efficient units. The existing units are inefficient compared to today’s high efficiency units. The efficiencies are estimated based on the age of the equipment. The efficiency of the existing units is estimated to be 10 SEER in cooling operation. This ECM includes installation of new rooftop units to replace the existing units. New high efficiency rooftop units are based on Rheem’s packaged units and split system units. Cooling efficiency is 14 SEER. These units will replace several of the split system units ranging from 1.5 to 5 tons. Energy Savings Calculations: Average Electric costs: $0.148 / kWh (*based on summer time average rates)

ECM #5: Lighting Upgrades Description: Compact fluorescent lamps (CFL’s) were created 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. Metal halide fixtures are utilized in the gymnasium of Overbrook High School. The 400 watt metal halide fixtures are fairly efficiency than, however they have some draw backs including poor lumen maintenance (approximately 30% reduction in lighting output at 40% of rated lamp life). Also, the fixture ballast can be noisy, require up to 10 minutes to re-strike after shutdown, and there is a noticeable color shift as the lamp approaches the end of its life. T-5 and T-8 high output fixtures are designed to be direct replacements for old metal halide fixtures. T-5 & T-8 fixtures are more efficient than probe start metal halides, as well as provide excellent lumen maintenance, no color shift, and minimal warm up time. This ECM includes replacement of all incandescent bulbs to compact fluorescent bulbs. Where the existing fixture is controlled by a dimmer switch, the CFL bulb must be compatible with a dimmer switch. The energy usage of an incandescent compared to a compact fluorescent is 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. This ECM also includes installation of T-5 high output fluorescent fixtures to replace the existing metal halide fixtures. The fluorescent replacement for metal halide fixtures uses approximately 40% less energy. The life span and total replacement cost of metal halides and fluorescent fixtures are similar and therefore maintenance savings are minimal. Est. Hours of Operation: Classrooms, Bathrooms, & Office: 2600 Hrs per year. Restrooms: 1300 Hrs per year. Hallways: 3600 Hrs per year. Storage rooms and janitor closets: 800 Hrs per year. Exterior Lights: 4200 Hrs per year.



Energy Savings Calculations: Refer to the Investment Grade Lighting Audit Appendix for a detailed energy savings calculation for the replacement of the incandescent lamps with compact fluorescent lamps. From the NJ Smart Start Appendix, the installation of new T-5 fluorescent fixtures in lieu of the existing 400W metal halide fixtures warrants the following incentive:

ECM #6: Lighting Occupancy Sensors / Daylight Sensors Description: In some areas the lighting is 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 achieved for “Occupancy Sensors for Lighting Control” average 20%-28%. 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 20% to 28% of the total light energy controlled by daylight or combination of control technologies (savings vary depending on space type and conditions surveyed in the field. The majority of the savings is expected to be after school hours when rooms are left with lights on. This ECM includes replacement of standard wall switches with sensors wall switches for all 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. The calculations adjust the lighting power usage by the applicable percent savings for each area that includes lighting controls. Energy Savings Calculations:

ECM #7: High School Kitchen Exhaust Hood Controls Description: The Pine Hill High School kitchen is equipped with two exhaust hoods for the cooking ranges. The size of each range hood is 4’x20’. The kitchen exhaust fan is controlled manually by a switch on the kitchen hoods. Standard kitchen hood controls consist of switches and relays that interlock the kitchen grease hood exhaust fan(s) with the 100% outside air unit that provides make-up air for this system. Normal occupation of kitchen hood system is limited to occupied hours. During the site inspection it was noted that the kitchen exhaust fan runs for approximately 4 hours a day. Based on the operation, there is great potential energy savings through better controls of the hood exhaust fan and make-up air unit. It should be noted that make up air is supplied via transfer air from the food line area and adjacent corridors. This energy conservation measure involves installing a Melink Kitchen Hood Variable Air Volume Controller; variable frequency drive on the kitchen hood exhaust fan; and turn off all the kitchen hood exhaust systems when the kitchen is closed. When the cooking appliances are turned on, the hood exhaust fan speed will increase based on the hood exhaust temperature. During heavy cooking, the kitchen hood exhaust fan increases to 100% speed until the smoke/vapor is removed. Energy savings are also realized when the kitchen equipment is operating at less than full load due to minimal cooking operations. During these times the fan speed decreases, removing only the necessary amount of air, saving exhaust fan energy and make up air conditioning energy. Energy Calculations Summary: Detailed calculations for the proposed kitchen hood control system can be found in the Kitchen Exhaust Calculations Appendix. It is pertinent to note that the calculation assumes the exhaust fans and make-up air unit are manually turned on for approximately 9 hours per day. Installed cost of the kitchen hood control system is $32,237.

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 municipality 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 energy produces clean energy and reduces a building’s carbon footprint. This is accomplished via photovoltaic panels which can be 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). 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 a vehicle under the array, this way no parking lot area is lost. The state of New Jersey 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. CEG has reviewed the ground area near-by being audited for the purposes of determining a potential for a parking lot canopy system. A ground area of 15,000 S.F. can be utilized for a PV system, totaling. A depiction of the area utilized is shown in Renewable / Distributed Energy Measures Calculation Appendix. Using this square footage it was determined that a system size of 211.37 kilowatts could be installed. A system of this size has an estimated kilowatt hour production of 258,221 KWh annually, reducing the overall utility bill by approximately 16% 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 ground space for the existing area around the facility. 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 81%. 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 State Police Barracks 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:

Table 9 Financial Summary – Photovoltaic System

FINANCIAL SUMMARY - PHOTOVOLTAIC SYSTEM

PAYMENT TYPE SIMPLE PAYBACK

INTERNAL RATE OF RETURN

Direct Purchase 13.15 Years 6.3% *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 High School to invest in a solar system through a Direct Purchase CEG does not recommend the High School pursue this route. It would be more advantageous for the High 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 Solar Arrays to the High School at a reduced rate compared to their existing electric rate. If Overbrook High School were to find additional funding to reduce the solar system installation costs, a direct purchase option could become increasingly favorable over a PPA and would become the preferred recommendation. 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 average wind speed is not adequate for purchase of a commercial wind turbine. Therefore, wind energy is not a viable option to implement.



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 Electric Usage Profile demonstrates an a-typical load profile with respect to the other schools in the district. The lowest consumption and demand occur in the months of July through September. This is a result of the low occupancy of the school in the summer, however it is unexpected in the month of September when school is in session and there is an increased cooling load. The remainder of the year shows the largest usage spanning the months of December through March. This is a result of electric resistance heat provided for various locations throughout the building. The demand has a fairly steady profile throughout the school months. The demand in the summer months drops dramatically with the reduction in occupancy levels. The load profile shows the potential schools to minimizing electric usage in unoccupied seasons. The overall load factor (L.F.) of the building is 41%. This is the highest load factor of all of the schools in the district. Load factor is the total usage divided by the demand times the hours. A load factor of 41% means that the equivalent full load electrical draw accounts for 41% of the total time. Load factor is a measurement of a building’s unpredictability with respect to electric use. A high load factor means the building’s electric use is steadier and therefore more advantageous for energy suppliers. In general terms, a higher load factor of 50% or more along with a flat load profile will allow for more competitive energy prices when shopping for alternative suppliers. Natural Gas: The natural gas usage profile demonstrates a very typical heat load profile. The summer months demonstrate very low consumption July through September. There is an increase in consumption October through June. The demand for natural gas is noted to extend very close to the school months. This is due to the boiler operation which must remain operation to provide the building’s domestic hot water. Heat is provided for this facility by natural gas-fired boilers. There are no supplemental gas fired hot water heaters at this facility. A base-load shaping (flat profile) will secure more competitive energy prices when procuring through an alternative energy source.



Tariff Analysis: Electricity: This facility receives electrical service through Atlantic City Electric on their Annual General Service (AGS-Secondary) rate. This service classification is available for general service purposes on secondary voltages. This facility’s rate is a three phase service at secondary voltages. For electric supply (generation), the customer has the option to purchase energy through the utility’s Generation Charge or a Third Party Supplier (TPS). This facility utilizes the generation service provide through Atlantic City Electric (BGS), Therefore, they will pay according to the default service. The Delivery Service includes the following charges: Customer Charge, Distribution Charge (kW Demand), Reactive Demand Charge (kvar Demand, over 1/3 kW), Distribution Charge kWh, Non-utility Generation Charge, Societal benefits Charge kWh, Regulatory Assets Recovery Charge kWh, Transition Bond Charge kWh, Market Transition Charge Tax kWh, System Control Charge kWh, CIEP Standby Fee kWh, Transmission Demand Charge kW, Reliability Must Run Transmission Surcharge kWh, Transmission Enhancement Charge kWh, Basic Generation Service Charge kWh, Regional Greenhouse Gas Initiative Recovery Charge kWh, Infrastructure Investment Surcharge. The Demand charges are based on a ratchet demand rate of 80% of the highest demand set in the months of June through September. The usage charges are based on a stepped rate structure. The demand charges are approximately equal to usage charges on a typical basis making this rate structure somewhat dependent on demand for the delivery portion of the electric charges. The steps for the usage charges are very small increments of change which result in fairly steady costs per kWh per month, however the rates do increase in the summer significantly compared to the winter. The average summer (June through September) electric rate is 18% higher than the average winter electric rate. Natural Gas: This facility receives natural gas service through South Jersey Gas Company on its General Service Gas rate. This is a firm delivery service (higher level of delivery) for general purposes where 1) customer does not qualify for any other rate schedule. Customers may either purchase gas supply from a Third Party (TPS) or from Public Services Basic Gas Supply Service default service as detailed in the rate schedule. This service has a much higher priority of delivery, based on the pipeline capacity. The “firm” service is the highest priority, and does not get interrupted. This rate schedule has a Delivery Charge Mechanism which includes: Basic Gas Supply Service Charge, Capital Investment Recovery Charge, Transportation Initiation Charge, Societal Benefits Charge, Temperature Adjustment Charge, Balancing Service Charge, Economic Development Rate Charge, Conservation Incentive Program Charge, and Energy Efficiency Tracker Charge. The customer can elect to have the Supply Charge (Commodity Charge) serviced through the utility or by a Third Party Supplier (TPS). Note: If the facility should choose to utilize a third party supplier (TPS) and the TPS not deliver, the customer may receive service from South Jersey Gas under Emergency Sales Service. Emergency Sales Service carries an extremely high



penalty cost of service. Should the TPS un-deliver to the utility on behalf of the client, the utility will automatically supply this default service to the client. Imbalances occur when Third Party Suppliers are used to supply natural gas, full-delivery is not made, and when a new supplier is contracted or the customer returns to the utility. It is important when utilizing a Third Party Supplier, that an experienced regional supplier is used. Otherwise, imbalances can occur, jeopardizing economics and scheduling. Recommendations: CEG recommends a global approach that will be consistent with all facilities within the BOE. Based on the latest electric utility bill, the average price per kWh (kilowatt hour) for the building based on 1-year historical average price is $.1200/kWh (this is the average “price to compare” if the client intends to shop for energy). The average price per decatherm for natural gas based on 1-year historical average price is $ 11.89 / dth (this is the Marketer Gas charges for comparison if the client intends to shop for energy, dth is the common unit of measure). Energy commodities are among the most volatile of all commodities, however at this point and time, energy is fairly competitive. The prices currently paid for electric and natural gas appear to be only slightly high for electricity and fairly high for natural gas compared to the average reported prices from the Energy Information Administration website (EIA) for the past few months. The average retail price for electricity in 2008 was $.1444/kWh (this is the overall retail price). The average third party supply price for natural gas in Dec-09 through Feb-10 was $10.70/ dth (this is the commodity costs only). It is recommended that the BOE consider procuring energy through alternative supply sources to shop for the most competitive prices. CEG also recommends that the BOE schedule a meeting with the current utility providers to review their utility charges and current tariff structures for electricity and natural gas. This meeting would provide insight regarding alternative procurement options that are currently available. Through its meeting with the Local Distribution Company (LDC), the BOE can learn more about the competitive supply process. Pine Hill can acquire a list of approved Third Party Suppliers from the New Jersey Board of Public Utilities website at www.nj.gov/bpu. The BOE should consider using a billing-auditing service to further analyze the utility invoices, manage the data and use the information for ongoing demand-side management projects. Furthermore, special attention should be given to credit mechanisms, imbalances, balancing charges and commodity charges when meeting with the utility representative. The BOE should ask the utility representative about alternative billing options, such as consolidated billing when utilizing the service of a Third Party Supplier. Finally, if the supplier for energy (natural gas) is changed, closely monitor balancing, particularly when the contract is close to termination. This could be performed with the aid of an “energy advisor”.



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%.

CEG recommends the BOE 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 in order to limit energy use from task lighting.

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. Seal openings around window unit penetrations to minimize outside air infiltration.

G. Turn off computer monitors and set computers to sleep when not being used. Computer monitors and computers are becoming one of the largest energy consumers in buildings today. Set computers to sleep when not being used and automatically turn off the computer monitors. Do not set computer monitors to “screen saver” mode which saves the screen life, not energy.



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 incentive programs. Incentive 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 by the owner. Utility information including usage and costs is estimated where incomplete data is provided.

NET PRESENT VALUE = -$6,026 ; INTERNAL RATE 10 YEARS @ 15% OF RETURN (IRR) = 9.4 %

NOTE:

Net After-tax Cash Flow is calculated as follows: NATCF = SAVINGS - COSTS - TAX RATE(SAVINGS - COSTS - DEPRECIATION)

Net Present Value is calculated as follows: NPV = C(0) + C(1)/(1 + r) + C(2)/(1 + r)^2 + ... + C(n)/(1 + r)^n (where C(n) is the net cash flow for the nth year and r is the opportunity cost of capital)

IRR is calculated by trial and error using the formula: NPV = C(0) + C(1)/(1 + IRR) + C(2)/(1 + IRR)^2 + ... + C(n)/(1 + IRR)^n
