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:

• ECM #4: Condensing Unit Upgrade

• ECM #10: Lighting Upgrade - General

• ECM #11: Lighting Controls

• ECM #12: CRT Monitor Replacement

Although ECMs #7 and #9 do not provide paybacks in less than 10 years, it is recommended to proceed with them. The installation of a dishwasher and electric booster heater as suggested in ECM #7 (or equal) for the Culinary Arts & Hospitality kitchen is recommended since the existing dishwasher and electric booster heating units are past their expected lifespan and will have a considerable energy and water reduction. It is recommended to proceed with Retro-commissioning in the near term and DDC controls for the long term as suggested in ECM #9 (or equal). This will allow energy savings in the near term using the equipment and controls already in place. The long term plan would connect heating, ventilation and air conditioning equipment to the DDC control system to provide the benefits of DDC control and reduce the energy consumption.

As part of ECM#9, based on the review of the facility’s energy bills and discussions with the CCTEC personnel, the energy audit team recommends Retro-Commissioning of this facility to meet the following objectives:

• Bring existing HVAC equipment to its proper operational state including air and water distribution systems

• Reduce energy use and energy costs • Improve indoor air quality • Verify the installation and performance of identified system upgrades • Address overall building energy use and demand and identify areas of highest energy use

and demand • Identify the location of the most comfort problems or trouble spots in the building • Review current O&M practices

Through the implementation of a Retro-Commissioning Plan, the Cumberland County Technical Education Center will be able to continue with their vision of reducing energy usage and operating efficient facilities. Indicated in the next section is the “Combined Project Approach” detailing a recommended packaging of energy conservation measures that provides a suitable payback as compared to implementation cost and resulting energy cost savings.



Combined Project Approach: Although individual projects with a simple payback of 10 years and less are considered financially self sustaining, it is important to consider how multiple projects can be combined together. When ECMs are aggregated into a single project, the lower cost ECMs provides valuable savings to offset the higher cost ECMs.

The Energy Savings Improvement Program (ESIP) allows for financing of any combination of energy efficiency projects into one large project. The term of the financing must be under 15 years and the savings provides the revenue for the financing cost. The combination of all projects into one large energy efficiency project provides Cumberland County Technical Education Center with the opportunity to implement ECM #4, #7, #9, #10, #11 and #12 as identified within this report with an overall simple payback of 9.2 years. This option allows Cumberland County Technical Education Center to implement much needed infrastructure improvements such as new air conditioning condensing unit, dishwasher and booster water heater, DDC controls and Retro commissioning, high efficiency lighting, lighting controls and to upgrade the remaining CRT computer monitors to the more efficient LCD monitor for the facility. The program financing allows for the implementation with no upfront cost for Cumberland County Technical Education Center. Implementation of an ESIP provides significant benefits and should be strongly considered for Cumberland County Technical Education Center. The total Entity Project Summary table below shows the savings, costs, incentive programs and paybacks for all ECMs at Cumberland County Technical Education Center that can be combined and will have a payback in less than 15 years.

It is pertinent to note that if the CCTEC has available capital funds, these projects would be highly recommended for implementation and would not require the use of the ESIP legislation.

Implementation of all ECMs identified within the ESIP – Entity Total Project Summary table represents a total annual savings of approximately $39,613 for Cumberland County Technical Education Center. The description of each ECM is shown later in this report.



Capital Improvement Energy Conservation Measures: The ECMs that have much longer paybacks are considered capital improvement ECMs. These ECMs typically have high installation costs that are more difficult to justify the savings 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 HVAC equipment upgrades, electric motor upgrades and building envelope improvements. The savings identified for the following ECMs provides additional incentive for Cumberland County Technical Education Center’s capital improvement projects.

Although ECM #1 does not provide a payback less than 10 years, it is recommended to proceed with the installation of efficient rooftop heating and ventilation units as suggested in ECM #1 (or equal) for the Gymnasium addition and East wing, since the existing rooftop heating and ventilation units are past their expected lifespan.

Although ECM #2 does not provide a payback less than 10 years, it is recommended to proceed with the installation of efficient rooftop units as suggested in ECM #2 (or equal) for the Main Building, since the existing rooftop units are past their expected lifespan.

Although ECM #3 does not provide a payback less than 10 years, it is recommended to proceed with the installation of efficient packaged cooling/heating rooftop units as suggested in ECM #3 (or equal) for the Board Office and South wing, since the existing packaged rooftop units are past their expected lifespan.

Although ECM #5 does not provide a payback less than 10 years, it is recommended to proceed with the installation of an efficient rooftop unit as suggested in ECM #5 (or equal) for the Main Building, since the existing rooftop units are past their expected lifespan and will have a considerable energy reduction.

ECM #6 does not provide a payback less than 10 years. The shop air compressor and paint booth fan motors are recommended for replacement. It is recommended when these motors are replaced, they should be replaced with premium efficient motors as suggested in ECM #6 (or equal) as they will provide a notable energy savings.

Although ECMs #8 and #8.1 do not provide a payback less than 10 years, it is recommended to proceed with the installation of new FRP doors, panels and windows as suggested in ECM #8.1 (or equal) for the CCTEC building envelope, since the existing known asbestos will be abated and there will be a notable energy reduction.



Other Considerations:

In addition to the ECMs, there are maintenance and operational measures that can provide significant energy savings and 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. Renewable Energy Measures (REMs) were also reviewed for implementation at the Cumberland County Technical Education Center. CEG utilized a roof and parking lot canopy mounted solar array to house a substantial PV system. The recommended 293.0 kW PV system will produce approximately 357,965 kWh of electricity annually and will reduce the schools electrical consumption from the grid by 25.05%. The system’s calculated simple payback of 14.56 years is past the standard 10 year simple payback threshold; however, with alternative funding this payback could be lessened. CEG recommends the Owner review all funding options before deciding to not implement this renewable energy measure. Overall Assessment: Overall, the Cumberland County Technical Education Center appears to be operating at a higher efficiency level compared to other schools in the region. With the implementation of the above recommended measures the Education Center will realize further energy savings at the Cumberland County Technical Education Center.



II. INTRODUCTION

The comprehensive energy audit covers the 120,543 square foot Cumberland County Technical Education Center Building, which includes the following spaces: Electrical Technology, Carpentry, Plumbing and HVAC Technology, Construction Trades, Automotive Servicing Technology, Auto Collision Repair Technology, Welding Technology, Cafeteria, Culinary Arts & Hospitality Kitchen, Health Occupations Dental, Cosmetology, Internet Technology, Digital Graphics, academic classrooms, atrium, offices, Conference Center, restrooms, Gymnasium, locker rooms, storage rooms and Maintenance 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 facility has one natural gas meter and five electric meters: the school, irrigation pump, sign, service for the house project and a rented area light for the house project. The electric power consumption is primarily the school building. The natural gas and electric data was provided as a summary total with a sample bill from each meter which provided an electric demand of 408 kW for the school. The electric usage profile represents the actual electrical usage for the facility. The demand profile is an estimated profile using the provided 408 kW as an assumed peak demand. Atlantic City Electric (ACE) provides electricity to the facility under their Annual General Service and Monthly General service rate structures. A Third Part Supplier (TPS) was not contracted during the period of the supplied energy data. 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 provides natural gas to the facility under the Basic General Supply Service (Firm Transportation) rate structure. Woodruff Energy, a Third Part Supplier (TPS), was contracted during the period of the supplied energy data. 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 facility has miscellaneous equipment used in a classroom setting for learning and troubleshooting. The equipment utilizes natural gas, propane, oil and electricity. One Gallon of #2 oil is equivalent to 140,000 BTUs of energy. One Gallon of propane is equivalent to 91,600 BTUs of energy. The equipment runs a minimal amount of time and does not have a significant impact on facility operation energy utilization. Therefore, this miscellaneous energy usage is ignored in this report. 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

NATURAL GAS USAGE SUMMARY



Figure 2 Natural Gas Usage Profile



B. Energy Use Index (EUI) Energy Use Index (EUI) is a measure of a building’s annual energy utilization per square foot of building. This calculation is completed by converting all utility usage consumed by a building for one year, to British Thermal Units (BTU) and dividing this number by the building square footage. EUI is a good measure of a building’s energy use and is utilized regularly for comparison of energy performance for similar building types. The Oak Ridge National Laboratory (ORNL) Buildings Technology Center under a contract with the U.S. Department of Energy maintains a Benchmarking Building Energy Performance Program. The ORNL website determines how a building’s energy use compares with similar facilities throughout the U.S. and in a specific region or state. Source use differs from site usage when comparing a building’s energy consumption with the national average. Site energy use is the energy consumed by the building at the building site only. Source energy use includes the site energy use as well as all of the losses to create and distribute the energy to the building. Source energy represents the total amount of raw fuel that is required to operate the building. It incorporates all transmission, delivery, and production losses, which allows for a complete assessment of energy efficiency in a building. The type of utility purchased has a substantial impact on the source energy use of a building. The EPA has determined that source energy is the most comparable unit for evaluation purposes and overall global impact. Both the site and source EUI ratings for the building are provided to understand and compare the differences in energy use. The site and source EUI for this facility is calculated as follows:

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

The typical hours of operation for this facility are Monday through Friday between 7:00 am and 10:00 pm. The school is occupied with 600 day students, 400 evening students, and 70 staff from 7:00 am through 10:00 pm. There are 3 day maintenance staff 7:00 am to 3:30 pm and 4 staff on the cleaning crew 3:30 pm to 11:00 pm Monday through Friday. The building is closed Monday through Friday 11:00 pm to 7:00am and all weekends.

The main building’s exterior walls are brick and block construction with minimum insulation typical of the time period. The original building’s wings are metal buildings with minimum insulation typical of the time period. The amount of insulation within the wall is unknown. The windows throughout the facility are in fair to poor condition and appear to be maintained. Typical windows throughout the facility are 1” clear tempered structural glass with steel tube frame. The existing metal doors are hollow and not insulated. The insulating panels in the window frame assemblies are metal and are known to have 1” asbestos insulation. Blinds are utilized in some of the rooms in the facility per occupant comfort but most rooms do not have blinds. The blinds are valuable because they help to reduce heat loss in the winter and reduce solar heat in the summer. The roof on the main building is an EPDM covering on 1 ½” rigid insulation board and 1 ½” metal decking. The amount of insulation below the roofing is unknown. The roofs on the wings are Standing seam metal roof and have approximately three inches of fiberglass batt insulation with a vapor barrier. The building was built in 1970 with a Gymnasium wing addition in 1982.

The main roof is scheduled for re-roofing this year. It will have new EPDM with some areas reusing existing insulation and some areas receiving new insulation and new EPDM.

The Gymnasium addition is a steel frame building having block wall construction with minimum insulation typical of the time period. The amount of insulation within the wall is unknown. The windows in the Gym addition are in good condition and appear to be maintained. Typical windows in the addition are double pane, ¼” clear glass with metal frame. The existing metal doors are hollow and not insulated. Blinds are utilized in some of the rooms in the facility per occupant comfort but most rooms do not have blinds. The blinds are valuable because they help to reduce heat loss in the winter and reduce solar heat in the summer. The roof on the addition is standing seam metal roof and has six inches of R-19 fiberglass batt insulation and an R-5 insulation board with facing.

The exterior man doors and asbestos insulated metal panels are scheduled for replacement this summer. They will be replaced with fiberglass reinforced plastic (FRP) doors with 1” insulated low-E glass and 1” insulated FRP panels. A bid alternate would replace the existing windows with low-E 1” insulated glass in addition to the base bid.



HVAC Systems

The main building is served by four MSI roof top multi deck air handling units with natural gas heat and direct expansion (DX) cooling with R-22 refrigerant. These units each have 500 MBH to 540 MBH natural gas input heating capacity and were 75% efficient when they were new. These units have a cooling capacity ranging from 262 MBH to 268 MBH (22 Tons nominal cooling, each). These units have a 5.3 EER. The multi deck unit maintains heating and cooling deck temperatures so a set of discharge dampers will modulate to maintain thermostat set point. The duct system is constant volume. This sequence was modified in the 1980’s to prevent mechanical cooling when a zone required heating. That modification would improve the system efficiency but lacks good control.

The MSI Multi deck systems are scheduled for replacement. The design documents for this indicate the MSI units being replaced with three AAON model RN-060 with DX cooling capacities ranging from 285.6 MBH to 592 MBH and full modulating natural gas heating capacities ranging from 270 MBH to 540 MBH. The units will be variable air volume (VAV) supply air with an energy recovery wheel. The existing duct systems will be replaced with a new duct system and VAV terminals with hot water reheat. VAV terminals are scheduled as Enviro-Tec model SDR. The Atrium is scheduled to have a fan powered VAV, Enviro-Tec model CFRWC. The project will include new DDC control for the control of the new roof top units.

The project includes the installation of a new AERCO water boiler model MLX-909 with 909 MBH natural gas input and 781-835 MBH output. There will be a boiler in-line circulation pump B&G model 2x2x7, 56 gpm at 12 feet head, 3/4hp. There will be a system circulation pump B&G model 1 1/2BC 76 gpm at 60 feet head, 3 hp.

There are electric cabinet heaters at corridor entry/exits. Maintenance staff stated that the power to these heaters have been turned off for a few years as the building is comfortable enough and deemed not required.

There are electric unit heaters in various, remote locations throughout the building. They range from 3 to 5.8 kW electric heating capacity and are controlled by local thermostats. They are at or past their ASHRAE expected useful service life and are in fair condition. Replacing these units



in kind would not provide any energy savings. Therefore, these units can be maintained/replaced as needed as a maintenance project.

There is a ductless split system in the Nurse’s Office and Maintenance office with capacities of 1 ½ and 1 Ton nominal cooling. These units are in good condition and have a few years of service life remaining.

The Culinary Arts & Hospitality Kitchen has four 11 ½ foot long hoods. They are configured in a 22 foot long back to back island over the cooking equipment. On the roof there are two Greenheck non-recirculating direct fired make up air units. One unit is model DG-115-H20-BD with 351.1 MBH natural gas input. The other unit is model DGX-115-H22-DB with 405.1 MBH natural gas input. These units have remaining service life and should be maintained. There are two exhaust fans, Greenheck model CUBE-240-20-S having a 2 hp motor and model CUBE-200-30-S having a 3 hp motor. The fans were installed in 2004, are in good condition and should be maintained.

There is one Weil McLain model 478 series 1, dual fuel water boiler. The boiler can operate on #2 oil or natural gas. The boiler serves the greenhouse, is in good to fair condition and has 14 years of ASHRAE expected useful service life remaining.

Exhaust System

Air is exhausted from the toilet rooms through the roof exhausters. The exhaust systems run 24/7.

There are local exhaust systems for dust collection in Carpentry, Automotive service and Auto Collision repair and Welding Technology. The fans are controlled locally and are operated as needed.

HVAC System Controls

The HVAC systems within the facility are controlled manually via electronic local thermostats. There is a Johnson Metasys DDC system that can control the occupancy and set points for the wings but is used basically to monitor the systems. The wings are served primarily by heating and ventilation units. The units have individual room thermostats that are controlled by the DDC system. There is an electronic control panel that controls the gym addition. The panel has occupied/unoccupied and automatic control modes by means of time clocks. The maintenance staff stated that these systems run 100%, 24/7 and don’t know if the controls work.

The project to replace the Multi deck units will include a DDC system to control the units in that project. It is unknown if the two DDC systems will be tied together. The assumption is that they will not be tied together.



Domestic Hot Water

Domestic hot water for the building is provided by two water tube boilers A.O. Smith model GW-55-200 with 500 MBH natural gas input each. The domestic hot water is drawn through each boiler and pumped into an A.O Smith storage tank (model GWT-500ASV0N100001) by fractional horsepower pumps. The system hot water recirculation pump is a fractional horsepower pump. The circulation pump is controlled by an aqua stat. The domestic hot water piping insulation appeared to be in good condition.

Lighting The majority of the interior lighting throughout the Cumberland County Technical Education Center building is provided by fluorescent fixtures with older generation, 700 series 32W T8 lamps and electronic ballasts. The kitchen hood, restroom and some exit signs are lit with incandescent lamps. The Atrium lighting is provided by compact fluorescent lamps. Finally, the exterior of the Cumberland County Technical Education Center is illuminated with 400W Mercury Vapor post mounted area lights and 175 watt mercury vapor wall packs.

Refer to the Major Equipment List Appendix for this facility.



VII. ENERGY CONSERVATION MEASURES Description: The Gym addition has two (2) gas fired heat and ventilation (H&V) units which provide heat to the Gymnasium and one (1) H&V unit that serves the Boy’s Locker room. There are two (2) Trane Model GDNC040/HBAC and one (1) Trane model GDNC/HBAC200 that are twenty-eight (28) years old in fair to poor condition. The current units have a combustion efficiency of 76% but the age of these unit heaters in conjunction with radiation losses has brought the efficiency down to approximately 71%. These units have surpasses their ASHRAE expected useful service life. The existing electric fan motors equal to or greater than one horsepower ranged from 78 to 93% efficient. The improved efficiency of the NEMA premium efficient motors is primarily due to better designs with use of better materials to reduce losses. Surprisingly, the electricity used to power a motor represents 95 % of its total lifetime operating cost. Because many motors operate 40-80 hours per week, even small increases in efficiency can yield substantial energy and dollar savings. This energy conservation measure will replace three (3) gas fired units serving the Gym and Boy’s Locker room. The existing units will be replaced with higher energy efficient units with capacity typical of the existing units. This energy conservation measure would replace all motors equal to or greater than 1 HP with NEMA Premium® Efficient Motors. Calculations are based on the following equipment: two (2) Trane model GGBA50PAA, 400 MBH input and one (1) Trane model GGBA20PAA, 200 MBH input with both models having 80% combustion efficiency or equivalent.

ECM #2: Roof Top H&V Unit Upgrade

Description: The building has twenty (20) roof top gas fired heat and ventilation (H&V) units which provide heat to various spaces in the wings. The units are inefficient compared to today’s standard and can be replaced with more efficient units. The existing units have a combustion efficiency ranging from 75% to 80% (75.45% weighted average) but the age of these unit heaters in conjunction with radiation losses has brought the efficiency down to approximately 70.45%. These units have surpasses their ASHRAE expected useful service life. The existing electric fan motors equal to or greater than one horsepower ranged from 78 to 93% efficient. The improved efficiency of the NEMA premium efficient motors is primarily due to better designs with use of better materials to reduce losses. Surprisingly, the electricity used to power a motor represents 95 % of its total lifetime operating cost. Because many motors operate 40-80 hours per week, even small increases in efficiency can yield substantial energy and dollar savings. This energy conservation measure will replace twenty (20) gas fired units serving the Wings. These units are identified in APPENDIX D – Major Equipment List. The existing units will be replaced with higher combustion efficient units with capacity typical of the existing units. This energy conservation measure would replace all motors equal to or greater than 1 HP with NEMA Premium® Efficient Motors.

ECM #3: Packaged Cool/Heat Rooftop Unit Upgrade Description: The Cumberland County Technical Education Center Building has two (2) packaged, direct expansion cooling-natural gas heat packaged rooftop units (RTUs). The unit’s cooling efficiencies are as shown below. The existing units have a combustion efficiency of 80.5% when new. Due to the age of these unit heaters in conjunction with radiation losses has brought the efficiency down to approximately 75.5%. One unit is at the end of its ASHRAE expected useful service life and the other is past its expected service life. The units are in poor condition and in need of replacement. The efficiencies of the existing units are below today’s standards for cooling efficiency. The proposed units are high efficiency one-for-one replacements of the existing units. The owner should have a professional engineer verify heating and cooling loads prior to moving forward with this ECM. This ECM includes installation of two (2) high efficient packaged rooftop units. The ECM calculations are based on Trane Packaged Rooftop Units or equivalent. Means Costworks software is used to estimate demolition and labor costs for a generic rooftop AC unit replacement. Full Load Cooling Hrs = 900 hrs/yr. Average Cost of Electricity = $0.156/kWh

ECM #5 Multi-deck RTU Upgrade with Energy Recovery Description: The Cumberland County Technical Education Center Main building is heated and cooling by four large MSI multi-deck air handling units. The units provide heating with natural gas furnace with 75% combustion efficiency. Each of the four units provide direct expansion cooling using R-22 refrigerant with capacities ranging from 262 MBH to 268 MBH. The unit efficiencies are calculated at 5.1 to 5.3 EER. The multi-deck unit maintains heating and cooling deck temperatures so a set of discharge dampers will modulate to maintain thermostat set point. The duct system is constant volume. This sequence was modified in the 1980’s to prevent mechanical cooling when a zone required heating. That modification would improve the system efficiency but lacks good control. Even with the modification to the operation sequence, the heating and cooling efficiencies are very inefficient compared to today’s standards. The units are forty-one years old, in poor condition and should be replaced. The existing units were installed using 0.5 CFM per square foot for outside air volume. Today’s requirements for outside air have changed and the owner should consult with a professional engineer for that analysis. To save cost on the significant energy required to condition outside air, an energy recovery unit can provide the ventilation required for the unit and space while capturing the heat otherwise exhausted from the building. An energy recovery unit also provides valuable energy savings in the cooling season by pre-cooling the outside air to the unit’s cooling coils with the cool room air otherwise exhausted. This ECM includes removing the four roof top MSI multi-deck units, ductwork and controls; the installation of three heating and cooling roof top units with air-to-air energy recovery, ductwork, variable air volume terminal boxes with hot water reheat, boilers, pumps, piping, valves and appurtenances, and DDC controls. The basis for this ECM is the AAON RN series units with air-to-air energy recovery and two Aerco MLX-909 boilers. It is recommended to perform airflow measurements of the existing equipment to verify the O.A. quantities prior to implementation of this ECM. It is also recommended to have a professional engineer provide further review of the equipment selection and load analysis prior to implementing this ECM. The equations used in the energy savings calculations are listed below. The input data and calculation results are in the tables in the APPENDIX G – ENERGY RECOVERY ENERGY CALCULATIONS appendix.

ECM #6: NEMA Premium Efficient Motor Upgrade Description: Replacing the old electric motors with new efficient motor is a simple change that can provide substantial savings. The Shop air compressor motor and the paint booth motor are past their ASHRAE expected useful service life and should be replaced. Existing electric motors equal to or greater than one horsepower ranged from 78 to 93% efficient. The improved efficiency of the NEMA premium efficient motors is primarily due to better designs with use of better materials to reduce losses. Surprisingly, the electricity used to power a motor represents 95 % of its total lifetime operating cost. Because many motors operate 40-80 hours per week, even small increases in efficiency can yield substantial energy and dollar savings. This energy conservation measure would replace all motors equal to or greater than 1 HP with NEMA Premium® Efficient Motors. NEMA Premium® is the most efficient motor designation in the marketplace today. Using MotorMaster+, Version 4, the energy & cost savings were calculated for the fan/pump motors in this facility that are greater than or equal to 1 HP. Energy Savings Calculations:

Existing: A 25 HP system air compressor Motor with the following characteristics: Existing Motor Efficiency = 88.5% 1 HP = 0.746 Watt Load Factor = 75% Cost of electricity = $0.156 / kWh Annual Hours of Operations = (20min/60min/hr)x15hr/dayx5days/wkx52wks/yr Annual Hours of Operations = 1300hrs/yr Existing 25HP Motor Operating Cost = {0.746 Watt/HP x Motor HP x Load Factor x Hours of Operation x Cost of Electricity] ÷ Motor Efficiency = [0.746 x 25 x 0.75 x 1,300 x 0.156] ÷ 0.885 = $3,205.27 / Year New NEMA Premium Motor Efficiency = 93.6% New NEMA Premium Efficiency Motor Operating Cost = {0.746 x 25 x 0.75 x 1,300 x 0.156} ÷ 0.936 = $3030.63 / Year Savings = $3,205.28 - $3,030.63 = $174.65/ Year Installed Cost of a 25 HP NEMA Premium® Efficiency Motor = $4,060.



This motor does not qualify for an incentive because the operation hours are less than 2000 hour per year. Simple Payback = $4,060 / $167 = 24.3 Years kWh saved = $167 / $0.149/kWh = 1120.8 kWh kW saved = 1120.8 kWh /1,300 hrs./yr. = 0.86 kW

ECM #7: Dishwasher & Booster Heater Upgrade Description: The original dishwasher was a Hobart model AM9T2. It has been upgraded with Hobart AM14 controls. The dishwasher was originally installed in 1970 and upgraded in the 1980s. The existing booster water heater is a Hatco model C-12 and is twenty eight years old and in fair to poor condition. Both the dishwasher and booster water heater are past their useful service life and should be replaced. Since this equipment was installed, there have been improvements made in the washing technology that results in about a 50% water savings. The reduced water requirements translates to less water heating, less water treating and less chemicals that will be used and dumped down the drain. There have been improvements in electric motor technologies. Existing electric motors equal to or greater than one horsepower ranged from 76.7% to 86.5% efficient. The improved efficiency of the NEMA premium efficient motors is primarily due to better designs with use of better materials to reduce losses. Replacing an electric water heater with a natural gas water heater would provide an estimated fuel savings of $895 / year. However, there are several obstacles with this particular location. First, there is a very large premium cost for the natural gas fired booster water heater. The Hatco model PMG-60 has a $5,490 list price premium over the Model C-12 electric heater. Second, the gas unit is larger than the electric unit so additional floor space would be used. There are three possible locations within 20 feet of the dishwasher that could be utilized. Third, a new gas vent would need to be installed and extended up through the roof. Fourth, a natural gas line would need to be extended for the new gas unit. Existing drawings show a 1” valve and cap for future booster heater located within 20 feet of the water heater possible locations. Fifth, the CCTEC staff indicated a possible gas supply pressure problem. Currently all of the gas using kitchen equipment cannot be used at the same time or the stove will shut down to just standing pilot lights. It is recommended that CCTEC have the gas company investigate the gas pressure at the meter and at the kitchen. Last, in a discussion with a kitchen equipment consultant and sales representative at Urie Associates, they strongly advise against the use of any gas booster heater. This advice is based on thirty-plus years of experience and their experience is the gas booster heaters need frequent service and is much more costly for maintenance in addition to aggravation of owners with down time. Therefore, CEG will recommend using an electric booster heater for this ECM. This energy conservation measure would replace the dishwasher and booster water heater. This ECM will use the Hobart model AM15+BUILDUP dishwasher and Hatco model C-9 electric booster water heater for the basis of this ECM or approved equal. The existing dishwasher has a 1 HP motor and the new unit will have a 2 hp motor.

ECM #8: Building Envelope Upgrade Description: The windows in the Cumberland County Technical Education Center building are original windows to the 1970 building and 1982 Gymnasium wing addition. The typical windows throughout the facility are 1” clear tempered structural glass with steel tube frame and is assumed to have no thermal breaks. These windows are below today’s standards in insulation value and solar heat reflectivity. The age of the windows and construction methods contribute to the leakage rate of the building. These windows are in fair to poor condition. These factors lead to increased energy use in the cooling and heating season. There is no external architectural shading for the windows except at the school entrance. This ECM includes in the base bid the existing windows to remain and in the bid alternate the replacement of all identified existing windows in the building with 1” tempered structural glass windows with a low emissivity glass. The building has opaque insulating panels in the window walls. The insulating panels in the window frame assemblies are metal and are known to have 1” asbestos insulation. All of these panels are scheduled to be remediated and replaced with 1” insulated fiberglass reinforced plastic (FRP) panels in both the base bid and bid alternate. The bid alternate includes additional window area being replaced with 1” insulated FRP panels. The building has hollow, un-insulated metal doors. These doors are very inefficient. The man doors are scheduled to be replaced with fiberglass reinforced plastic (FRP) doors with 1” insulated low-E glass. The un-insulated metal roll-up doors are scheduled to remain. Building envelope improvements may require a significant investment. Typically, the investment is recovered through energy savings however; the payback is generally quite protracted. For example, in a drafty building, adding insulation or upgrading the windows would improve comfort. Human comfort impacts productivity as uncomfortable or unhappy occupants will have a higher absentee rate and/or will require additional time from maintenance personnel as they search for stopgap solutions to the comfort problem. Energy Savings Calculations: For the following energy savings calculations, we obtained heating and cooling degree days for the Millville Airport from the following: Source: www.degreedays.net (using temperature data from www.wunderground.com) Station: Airport: Millville, NJ, US (75.07W, 39.37N) Station ID: KMIV

The window, panel and door areas were derived from drawings provided by Garrison Architects and photographs of this facility. The equations used in the calculations are listed below. A spread sheet was used to perform the calculations and tabulated. The energy transfer through each wall, window and roof was calculated using the appropriate material area, U-value and temperature



difference. The sum of all the energy transfer for each part is the total energy transfer. The calculations are located in the APPENDIX F –ENERGY CALCULATION – ENVELOPE UPGRADE appendix.

ECM #9: DDC Control Description:

The HVAC systems within the facility are controlled manually via electronic local thermostats. There is a Johnson Metasys DDC system that can control the occupancy and set points for the wings but is used basically to monitor the systems. The wings are primarily heating only roof top units that heat and ventilate the wings. The units have individual room thermostats that are controlled by the DDC system. There is an electronic control panel that controls the gym addition. The panel has occupied/unoccupied and automatic control modes by means of time clocks. The maintenance staff stated that these systems run 100%, 24/7 and don’t know if the controls even work.

Air is exhausted from the toilet rooms through the roof exhausters. The exhaust systems run 24/7. There are local exhaust systems for dust collection in Carpentry, Automotive service and Auto Collision repair and Welding Technology. The fans are controlled locally and are operated as needed. The large gang toilet room exhaust fans could be turned off during unoccupied nights and weekends and would save about 4600 hours of run hours per year, per fan. By turning these fans off, it will reduce the required heating and cooling of outside air (ventilation and infiltration).

The typical hours of operation for this facility are Monday through Friday between 7:00 am and 10:00 pm. The school is occupied with 600 day students, 400 evening students, 70 staff from 7:00 am through 10:00 pm. There are 3 day maintenance staff 7:00 am to 3:30 pm and 4 staff on the cleaning crew 3:30 pm to 11:00 pm Monday through Friday. The building is closed Monday through Friday 11:00 pm to 7:00am and all weekends.

There is no thermostat adjustments made and set back/set up functions are not employed. Therefore, a DDC system providing the Owner with full control over the HVAC equipment within the building appears to be an energy saving opportunity. The installation of a Building Automation system with Direct Digital Controls (DDC) wired through an Ethernet backbone and front end controller is the typical solution to gain control over the HVAC systems and to minimize the system energy use. The Cumberland County Technical Education Center already has usable parts of the controls already in place. Another piece is planned to be installed as part of the roof and equipment replacement project that is planned for this year. In the near term, the existing equipment and controls should be re-commissioned to assure that they are operation as close as possible to their original design. The existing controls for the wings and Gymnasium addition should employ the unoccupied function. This should close of the outside air damper and change the fan motors from continuous on to only cycle on demand for heat or cooling. In the un-occupied mode, the temperature set points should be set back 68°F to 58°F for heating and set up 75°F to 85°F for cooling. This functionality can be employed in most of the building without much cost.



In the long term, all equipment replacement should include for each unit being replaced a unit DDC controller and a tie-in to the existing DDC system front end. The system replacements should include new thermostat controllers for all indoor air-handling systems and the rooftop units, in addition to each piece of equipment being wired back to a front end controller and computer interface. With the communication between the devices and the front end computer interface, the Owner will be able to take advantage of equipment scheduling for occupied and unoccupied periods based on the actual occupancy of the facility. The DDC system will also aid in the response time to service / maintenance issues when the facility is not under normal maintenance supervision, i.e. after-hours and week-ends. The new DDC system has the potential to provide substantial savings by controlling the HVAC systems as a whole and provide operating schedules and features such as space averaging, night set-back, temperature override control, etc. The U.S. Department of 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 referenced report:

• Energy Management and Control System Savings: 5%-15%. Savings resulting from the implementation of this ECM for energy management controls are estimated to be 10% of the total energy cost for the facility. The near term cost for retro-commissioning the existing building systems is $24,100. This includes air flows measurement, minor repair and adjustment. Anything larger than a minor repair is deemed a capitol improvement and would not be included. The long term cost of a partial DDC system to tie-in to the existing DDC system with new field devices, controllers, programming, etc. is approximately $2.00 to $3.00 per SF in accordance with recent Contractor pricing for systems of this magnitude. Savings from the implementation of this ECM will be from the reduced energy consumption currently used by the HVAC system by proper control of schedule and temperatures via the DDC system. Cost of partial DDC System = ($2.00/SF x 120,543 SF) = $241,086 For both the near and long term projects, the cost is $265, 186.

ECM #10: Lighting Upgrade – General Description: The majority of the interior lighting throughout the Cumberland County Technical Education Center 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, the kitchen hood, restroom and some exit signs still have incandescent lamps. It is recommended to retrofit or replace all of the incandescent lights in these areas with compact fluorescent lamps or LED exit signs. This ECM includes re-lamping of the existing fluorescent fixtures with 800 series, 28W T8 lamps. The ECM also includes retrofit of all older fluorescent fixtures with T8 or T5 fluorescent 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. Finally, the exterior of the Cumberland County Technical Education Center is illuminated with 400W Mercury Vapor post mounted area lights. It is recommended to retrofit these fixtures with



pulse start metal halide lamps and electronic ballasts. Pulse-start MH lamps have a high-voltage ignitor to start the lamp using a series of pulses instead of a starting probe electrode. Pulse start metal halide lamps typically have an increased lumen maintenance levels by up to 33%. This allows utilizing lower wattage lamps while maintaining the minimum lighting levels in the space. The 175 watt mercury vapor wall packs use an older, inefficient technology that should be replace with newer more efficient induction fixture. The induction lamp uses less than half the energy and has a rated life of 100,000 hours compared to the 24,000 hour for the mercury vapor lamp. Energy Savings Calculations: The Investment Grade Lighting Audit Appendix outlines the hours of operation, proposed retrofits, costs, savings, and payback periods for each set of fixtures in the each building. Rebates and Incentives: There are incentives available from NJ Smart Start® Program for a portion of the retrofits in this ECM. Incentives are calculated as follows: From the Smart Start Incentive appendix, the retrofit of a probe start metal halide with a pulse start system (with a minimum 12% wattage reduction) warrants the following incentive: Pulse Start Metal Halide (for fixtures ≥ 150 watts) = $25 per fixture. SmartStart ® Incentive # of Probe Start Fixtures $25 12 $25 $300 Induction Lighting HID Replacement = $70 per fixture SmartStart ® Incentive 175watt Mercury Vapor Wall Pack $70x30 $2,100 Linear Flourescent 400w HID replacement with T5 = $100 per fixture SmartStart ® Incentive 400w HID replacement $100x12 $1,200 Total Incentive = $300 + $2,100 + $1,200 = $3,600 Replacement and Maintenance Savings: Replacement and Maintenance Savings for Induction fixtures are calculated as follows:

ECM #11: 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 20% 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 or switch mount 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. The calculations adjust the lighting power usage by the applicable percent savings for each area that includes lighting controls. Energy Savings Calculations:

ECM #12: Computer Monitor Replacement Description: The computers throughout the school utilize a mixture of CRT computer monitors and LCD computer monitors. The CRT computer monitors within the offices and classrooms are outdated and have several disadvantages such as; significantly increased energy consumption, uses large amount of desk space, poor picture quality, distortions and flickering image, secular glare problems, 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 187 LCD monitor and 6 CRT monitors. Some of the monitors were left in screen saver mode, which 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 school district. The calculations are based on the following operating assumptions: Energy Savings Calculations: No. of CRT Monitors: 6 Operating Weeks per Yr: 42 Hrs per Week: 75 (15 hrs per day estimated average)

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 Cumberland County Technical Education Center 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 are mounted on the Main building roof. 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 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. CEG has reviewed the existing roof area and site of Cumberland County Technical Education Center for the purposes of determining a potential for a photovoltaic system. CEG believes a combination of a roof mounted and a ground mounted parking lot canopy system is best suited for this site. An area total of 20,800 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 293.02 kilowatts could be installed. A system of this size has an estimated kilowatt hour production of 357,965 KWh annually, reducing the overall utility bill by approximately 25.05% 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 roof and parking lot space at the existing 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 Technical Education Center 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:

Direct Purchase 14.56 Years 6.87% 5.3% *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 Technical Education Center to invest in a solar system through a Direct Purchase CEG does not recommend the Technical Education Center pursue this route. It would be more advantageous for the Technical Education Center 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 Technical Education Center at a reduced rate compared to their existing electric rate. 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 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 electricity usage profile demonstrates a steady year long load profile for facilities that have occupancy during the summer months. Average usage for all accounts combined is 119,094 kWh with highest usage during May, June, July, August and September. 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 and July 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), MGS (Monthly General Service) and SPL (Street and Private Lighting. The facilities have not contracted a Third Party Supplier (TPS) to provide electric commodity service. Account# 0329 9959 9999 is noted to have been under a 3rd party contract with TPS, Hess Energy for November and December 2010, however as of Jan 2011 the Supplier provided a letter stating that the account was to be turned back to the utility for BGS-FP supply. 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 facilities currently receive natural gas distribution service through South Jersey Gas on rate schedule General Service Gas – Large Volume Firm Transportation (GSGLV-FT) with a Firm Demand of 73mcf/day. Woodruff Energy is the contracted Third Party Supplier (TPS) which provides natural gas commodity supply service. The current contract price for natural gas supply is $5.88/dth for a term of Jan 2011 – Dec 2011. South Jersey Gas 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 link below for a recap of natural gas BGSS charges from South Jersey Gas for rate schedule GSGLV-FT. http://www.southjerseygas.com/108/tariff/bgssrates.pdf The utility, South Jersey Gas is 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. South Jersey Gas’s delivery service rate includes the following charges: Customer Service Charge, Distribution Charge, Demand Charge, & Balancing Service Charge.

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 (1/11/2011):

U.S. Natural Gas Prices. The Henry Hub spot price averaged $4.25 per MMBtu during December, an increase of about 54 cents from November's price of $3.71 per MMBtu. EIA expects the higher forecast production during the first half of 2011 compared with the same period last year, combined with a decline in consumption, to moderate natural gas spot prices. The projected spot price falls to a low of $3.73 per MMBtu in June then rises to $4.61 in December, averaging $4.02 per MMBtu for all of 2011, which is $0.37 per MMBtu lower than the 2010 average and $0.31 per MMBtu lower than in last month's Outlook. In 2012, the spot price rises to an average of $4.50 per MMBtu.

Uncertainty over future natural gas prices is slightly lower this year compared with last year at this time. Natural gas futures for March 2011 delivery (for the 5-day period ending January 6) averaged $4.39 per MMBtu, and the average implied volatility over the same period was 43 percent. This produced lower and upper bounds for the 95-percent confidence interval for March 2011 contracts of $3.21 per MMBtu and $6.02 per MMBtu, respectively. At this time last year, the natural gas March 2010 futures contract averaged $5.73 per MMBtu and implied volatility averaged 57 percent. The corresponding lower and upper limits of the 95-percent confidence interval were $3.88 per MMBtu and $8.47 per MMBtu.



U.S. Electricity Retail Prices. EIA expects the U.S. retail price for electricity distributed to the residential sector during 2010 to average 11.6 cents per kilowatt-hour, about the same level as in 2009. EIA expects the U.S. residential price to increase only slightly over the forecast period--by 0.6 percent in 2011 and by 1.0 percent in 2012.

Recommendations:

1. CEG recommends an aggregated approach for 3rd party commodity supply procurement strategies for 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 natural gas and explore options for utilizing an energy supply aggregation for electricity to include all AGS and MGS accounts. 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

2. 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 $50,000 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.

In addition to the recommendations above, implementing Retro-Commissioning would be beneficial for this facility. Retro-Commissioning is a means to verify your current equipment is operating at its designed efficiency, capacity, airflow, and overall performance. Retro-Commissioning provides valuable insight into systems or components not performing correctly or efficiently. The commissioning process defines the original system design parameters and recommends revisions to the current system operating characteristics.



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

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

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

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

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

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

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

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

G. Solar PV system REM assumes panel locations are acceptable. Before proceeding with the panel locations, a structural engineer must be consulted to determine the adequacy of the structures and whether or not structural modifications would be required.

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.
