3.0 EXISTING CONDITIONS
3.1 Building General
3.1.1 Structure
This energy audit evaluated four buildings at the STP with a combined area of approximately 7,600 square feet. The audited buildings include the Main Building, Main Pump Building, Treatment Plant, and the Micro Strainer Building as shown in Figure 1 below. The garage, which is also identified in the figure below is included in a separate energy audit report.
Figure 1. Ajax Terrace STP
3.1.1.1 Main Building
The Main Building, constructed in 1965, is a 3,450 square foot, concrete masonry unit (CMU) wall building on a concrete foundation with brick exterior. The building has a first floor and basement sectionand houses offices, wastewater pumps, electric panels, and an emergency backup electric generator. The windows are single pane glass with aluminum frames which were replaced in the 1990s and are in acceptable condition. The building has one main entrance and three other emergency exits. The roof system is flat, ballasted, with a rubber membrane, and is in scheduled to be replaced.
3.1.1.2 Main Pump Building
The Main Pump Building was constructed in 1988, and is an 880 square foot, CMU wall building on a concrete foundation with brick exterior. The building consists of a first floor and basement section and contains wastewater pumps and electric panels. The windows are single pane glass original to the building’s construction and are in good condition. The building has one main entrance and another emergency exit. The roof system, which is in good condition, is flat, ballasted, with a rubber membrane.
3.1.1.3 Treatment Plant
The Treatment Plant, consisting of five small single story CMU structures totaling 1,840 square feet, on concrete foundations with brick exteriors, was constructed in 1988. The structures support the thickener, primary clarifier, secondary clarifier, chemical and flow equalization operations, and house wastewater

pumps and electric panels. The single pane glass windows are original to construction, and are in satisfactory condition. The structures typically have one main entrance and one other emergency exit. The roof systems are flat, ballasted, with a rubber membrane, and in good condition.
3.1.1.4 Micro Strainer Building
The Micro Strainer Building, housing rotating filters and electric panels, was constructed in 1988. The1,496 square foot building with CMU walls on concrete foundations with brick exterior, has no basement. The windows are original, single pane and in good condition. The building has one main and one emergency exit. The roof system is flat, ballasted, with a rubber membrane, and is in good condition.
3.1.2 Operating Hours
The STP operates continuously year round.
3.1.3 STP Process
The Roxbury Township Ajax Terrace STP receives sanitary sewer flow from the Township via a gravity collection system and several offsite sewage pumping stations. The plant, sized to treat two million gallons per day (MGD), currently operates at 1.6 MGD. The plant uses a submerged attached growth aerobic process utilizing rotating biological contactors (RBCs). Treatment includes the followingprocess:
Mechanical Grit Removal Primary Clarification Biological Wastewater Treatment using RBCs Secondary Clarification Chlorination with Hypochlorite Fine Sediment Removal Dechlorination Sludge Thickening
The wastewater flow enters the plant via a gravity sewer line. A mechanical grinder breaks down large debris in the influent which is then pumped to the primary clarifier. Solids settle to the bottom of the clarifier, and are pumped to the sludge thickener using small sludge pumps turned on manually once a day. The influent flows by gravity to the rotating biological contactors. The plant is designed with four trains, each consisting of six stages. The flow travels equally to each train and then through each stage. The effluent flows to the pool by gravity where it is chlorinated with hypochlorite and agitated to completely mix the chemical. The effluent then flows to a rotating filter which removes the finer particles before the treated water is released to Lamington River. The existing site is approximately 80% utilized by the footprint of the treatment units.
3.1.4 Treatment Process
3.1.4.1. Mechanical Grit Removal
At the beginning of the plant, the wastewater flows through a grit remover, with two 3 HP motors rated at 93.5% efficiency. The flow is pumped via one of three 50 HP pumps, also rated at 93.5% efficiency, to a chamber which distributes the flow evenly to the primary clarifiers. During the winter, the flow is
New Jersey BPU - Energy AuditsPage 6 of 25
pumped to a secondary grit remover which spins the solids out using a screw conveyor and transfers the solids to a trash bin. The effluent then flows by gravity to the primary clarifiers.
3.1.4.2 Primary Clarification
Flow enters the primary clarifiers via gravity from the grit chamber. The plant utilizes two primary clarifiers; both are required at all times to meet process demands. These tanks allow the solids to settle out of suspension. The effluent flows by gravity to a chamber which equalizes the flow between the four RBC trains. Excess flow is sent from this chamber to the equalization basins, also by gravity, to maintaina constant flow to the RBCs. Flow is transferred from the basins by pumps operated manually back to the flow chamber to be distributed to the RBCs. The settled solids at the base of the clarifiers and solids skimmed off the top, are pumped manually, one cycle per day, using three 7.5 HP pumps to the Sludge Holding Tank. The efficiency of these motors was not available but was assumed to be 87.5% based on their age.
3.1.4.3 Biological Wastewater Treatment
Flow enters evenly into each RBC train. A train represents each chain of RBCs, and the plant currently operates four trains. Each train consists of six stages; each stage is one rotating biological contactor. The treatment process through each stage of the train is identical. All trains and stages are required to be in operation at all times to meet the flow demand of the plant. An RBC consists of a series of closely spaced circular disks of polystyrene or polyvinyl chloride submerged in wastewater and rotating through it. The RBC unit is partially submerged in the concrete basin containing the wastewater, and the disks rotate slowly. Each RBC is operated using 24 5-HP motors. The typical efficiency of these motors ranges between 87.5 to 89.5% based on nameplate data. As the RBC disks rotate out of the wastewater, aeration is accomplished by exposure to the atmosphere. Wastewater flows down through the disks and solid accumulated on the disks begins to fall off and out of suspension. This design process is historically effective in relation to the relatively low energy costs. The aerobic process is supplemented by 40-HPblowers rated at 93.5% efficiency, which continuously adds air to the RBCs. The plant has three blowers available, but only one is used at a time (each is cycled weekly). The settled solids are pumped manually, one cycle a day, to the Sludge Holding Tank.
3.1.4.4 Secondary Clarification
Similar to the primary clarifiers, flow enters the secondary clarifiers via gravity from the RBCs. Two secondary clarifiers are required to meet the plant’s demands. As in the previous processes, the settled solids are pumped manually to the Sludge Holding Tank, one cycle a day, using three 7.5 HP pumps. The efficiency of the motors was not available, but was assumed to be 87.5% based on their age. Flow travels from the clarifiers by gravity to the Chlorination Basin.
3.1.4.5 Chlorination
Flow enters the pond and is treated with liquid hypochlorite which is dosed using small pumps. The basin is lined and contains two mechanical agitators with two 35 HP motors, which operate continuously. The efficiency of each of the motors is 93.5%. The agitators aid in mixing the hypochlorite evenly throughout the effluent; treated effluent then flows by gravity to the mirco-strainers.
New Jersey BPU - Energy AuditsPage 7 of 25
3.1.4.6 Fine Sediment Removal
The mirco-strainers, which remove the fine suspended particles which will not settle out, are two rotating drums operated using two 7.5 HP motors. Efficiency was not available; assumed to be 87.5% based on age. Water enters the drums, and drum rotation pushes the effluent through the fine fabric at the perimeter of the drums and traps the particles inside. Particles are removed from the strainers by backwashing, and flow is pumped to the grit chamber using two 3 HP motors. Motor efficiency was not available, but assumed at 87.5% based on age. The backwashing process is manually operated, and the treated effluent leaves the micro-strainers by gravity and flows to the dechlorination basin.
3.1.4.7 Dechlorination
The effluent enters the basin and is dosed with sulfur dioxide using small dosing pumps. Some of theflow is sent to a non-potable water holding tank which serves the site’s fire hydrants. The remainder of flow enters a constructed baffle system to assist in chemical mixing. The effluent is then metered and released to the Lamington River.
3.1.4.8 Sludge Thickening
Several processes throughout the plant generate solid waste, which are pumped manually to the sludge thickener. The thickener basin allows the solids to settle, and produces supernatant, a layer of liquid on top of the solids. The supernatant is transferred by gravity to the head of the plant. The solids are pumped to a holding tank, where they are removed using a vacuum truck and hauled offsite.
3.2 Utility Usage
The STP uses electricity, natural gas, and municipal water.
Electricity is purchased and delivered by Jersey Central Power & Light (JCP&L), and natural gas purchased and delivered by New Jersey Natural Gas (NJNG). The facility does not purchase municipal water.
The Main Building, Main Pump Building, Treatment Plant, and the Micro Strainer Building all share a common electric and natural gas meter. The STP had an annual electrical consumption of 1,971,500 kWh at a cost of $295,600, and natural gas usage of 7,400 therms at a cost of $11,700. The total utility bill for 2008 for these buildings was $307,300. The largest portion of energy usage is for electricity and theaverage blended rate was $0.15 per kWh. The electrical usage trend shows higher consumption from November through April. The majority of natural gas is used for building heating as indicative of the higher usage trend during the colder months of November through April. The average rate for natural gas was $1.58 per therm. Utility data is provided in Appendix A.
Electricity and natural gas commodity supply and delivery are presently purchased from JCP&L and NJNG, respectively. The delivery component will always be the responsibility of the utility that connects the facility to the power grid or gas line; however, the supply can be purchased from a third party. The electricity or natural gas commodity supply entity will require submission of one to three years of past energy bills. Contract terms can vary among suppliers. A list of approved electrical and natural gas energy commodity suppliers can be found in Appendix A.

3.3 HVAC Systems
3.3.1 Heating
3.3.1.1 Main Building
Heating is primarily provided by hot water produced by a natural gas fired boiler and circulated through a piping system to three hot water unit heaters. The boiler is rated at 491 MBH input and is estimated to be 80% efficient. The Main Building’s HVAC systems consist of a mixture of programmable thermostats and temperature sensors for controlling space temperature.
3.3.1.2 Main Pump Building
The building does not contain a central heating system. Space heating is provided by two electric ceiling mounted unit heaters which distribute warm air to various parts of the building. Heat is controlled by wall mounted thermostats or unit mounted dial thermostats. The heaters are typically set at 55°F. None of the thermostats are programmable.
3.3.1.3 Treatment Plant
There are no central heating systems; space heating is provided by 11 electric ceiling mounted unit heaters which distribute warm air to various parts of each structure. Heat is controlled by wall mounted thermostats or unit mounted dial thermostats. The heaters are typically set at 55°F, and none of the thermostats are programmable.
3.3.1.4 Micro Strainer Building
There is no central heating system; four electric ceiling mounted unit heaters distribute warm air to various parts of the building. Heat is controlled by wall mounted thermostats or unit mounted dial thermostats. The heaters are typically set at 55°F; none of the thermostats are programmable.
3.3.2 Cooling
3.3.2.1 Main Building
The current AC system is comprised of one Carrier WeatherMaker rooftop unit (RTU) with a 7.5 ton capacity. This unit was installed in 1990 and is nearing the end of its useful life.
3.3.2.2 Other Buildings
The Main Pump Building, Treatment Plant, and the Micro Strainer Building are not air conditioned.
An equipment inventory is provided in Appendix B.
3.4 Lighting/Electrical Systems
The interior lighting within the STP is comprised mainly of inefficient T-12 fluorescent light fixtures. The T-12s are original to building construction and are all 4’fixtures. There are also approximately a total of (30) 36-watt compact fluorescent fixtures in the Main Pump Building and the Main Building. Lighting is controlled by individual switches in each space. The lighting within the buildings remains in
New Jersey BPU - Energy AuditsPage 9 of 25
use with occupancy. Most of the buildings within the STP are rarely occupied. It is estimated that the Main Building is occupied approximately 40 hours per week; the remaining buildings are occupied intermittently (2-3 hours per day) as necessary to maintain process operations.
It was noted during the walkthrough that many of the exit signs in the buildings were not illuminated and were “tactile” type. It is suggested that the existing non-illuminated exit signs be reviewed against the referenced standard ICC A117.1 for code compliance.
The buildings’ exterior lighting consists of a mixture of 70 and 150 watt high pressure sodium fixtures and 100 watt incandescent fixtures. The exterior lighting is controlled by timers.
3.5 Plumbing Systems
Hot water is produced by one A.O. Smith natural gas hot water heater (Model GCV 50 100) located in the restroom of the Main Building. The tank has a capacity of 50 gallons and utilizes 40,000 Btu/hr. The unit was installed in 2006.
The plumbing system consists of domestic water, sanitary, and vent piping. Plumbing fixtures includetoilets, sinks, and floor drains.

4.0 ENERGY CONSERVATION MEASURES
4.1 ECM-1 Lighting Replacements
A comprehensive fixture survey was conducted of the Roxbury Township STP. Each switch and circuit was identified, and the number of fixtures, locations, and existing wattages established. Most of the lighting consists of T-12 fluorescent fixtures with magnetic ballasts, which are regarded as inefficient by today’s standards. Each fixture is equipped with two, three or four 4-foot straight bulbs.
Overall energy consumption can be reduced by retrofitting approximately 133 T-12 fixtures with more efficient T-8 fluorescent lamps. Existing T-12 lamps and ballasts of each fixture can be replaced with electronic ballasts and two, three or four 4-foot, T-8 fluorescent lamps as required.
This measure will allow the facility to stock only T-8 fixtures in the future for all buildings. Presently, the facility has a mixture of T-12 lamps with multiple ballast combinations. In the future, the facility should only purchase low wattage super T-8s and ballasts such as the low wattage 4-foot 28-watt units. These lamps may be directly installed into any existing 34 watt fixture when lamps fail. By installing these lamps over time, the most efficient lighting system available will be consistent throughout the facility.
The fluorescent lighting retrofits have an expected life of 15 years, according to the manufacturer, and total energy savings over the life of the project are estimated at 475,500 kWh and $78,000.
The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

This measure is not recommended in lieu of ECM-3.
4.2 ECM-2 Install Occupancy Sensors
It is proposed that occupancy sensors be installed in select rooms to turn off lights when the area is unoccupied. A lighting survey was conducted of all fixtures to determine the average time lights are presently on in each space. Occupancy sensors were not considered in mechanical areas due to safety concerns. Other areas were not considered due to the proposed location of occupancy sensors. If a sensor does not have a clear view of the area, it may darken even with people in the space, creating an unsafe condition. Only the Main Building was considered for occupancy sensors. The remaining buildings contain process and mechanical areas and were not considered.
Lighting fixtures throughout the STP are manually turned on and off at switches located within the spaces. The lights are operational based on occupancy. Interior lights in the Main Building are operated approximately eight hours per day.
New Jersey BPU - Energy AuditsPage 11 of 25
Typical traffic patterns for each space were then taken into account to approximate the actual occupancy hours per day. Occupancy sensors were proposed in the office spaces, laboratory, and restroom within the Main Building. Seven occupancy sensors and some standard electrical work are required for this measure.
Lighting controls have an expected life of 15 years, according to the manufacturer, and total energy savings over the life of the project are estimated at 76,500 kWh, and $10,500.

4.3 ECM-3 Lighting Replacements with Occupancy Sensors
This measure is a combination of ECMs 1 and 2 to allow for maximum energy and demand reduction. Due to interactive effects, the energy and cost savings for occupancy sensors and lighting upgrades are not cumulative.
The lighting retrofits and controls have an expected lifetime of 15 years, according to the manufacturer, and total energy savings over the life of the project are estimated at 526,500 kWh, and $85,500.

4.4 ECM-4 Install Door Seals
The exterior doors are original to construction and the gaps around the perimeters result in air infiltration. Installing door seals will reduce infiltration and save energy. This measure determined the perimeter length and gap spacing for exterior doors in the Main Building, which is heated and cooled. The remaining complex buildings (Pump Building, Treatment Plant, and Micro Strainer Building) are not cooled and, therefore, were evaluated separately, as follows:
ECM-4a –Main BuildingECM-4b –Complex Buildings (Pump Building, Treatment Plant, and Micro Strainer Building)
Infiltration reductions and associated energy savings were then calculated by using weather bin heating and cooling hour data.
Door seals have an expected life of 10 years, according to the manufacturer, and total energy savings over the life of the project are estimated at 23,000 kWh, 700 therms, and $4,000.

4.5 ECM-5 Rooftop Unit Replacement (Main Building)
The existing rooftop unit on the Main Building is over 15 years’old and nearing the end of its useful life. This measure proposes to replace the existing 7.5 ton RTU with a new higher efficiency unit. The average energy efficiency ratio (EER) of the existing unit is approximately 7.0 EER; the proposed unit is approximately 11.5 EER.
Using bin weather data for Newark, NJ, the hours at which the outdoor air was 70 degrees or above were totaled to determine the annual runtime of the rooftop unit. Applying the existing and proposed EER values to the total cooling load and the annual hours of operation, the energy savings was estimated to be about 1,000 kWh per year.
New Jersey BPU - Energy AuditsPage 13 of 25
RTUs have an expected life of 20 years, according to ASHRAE, and total energy savings over the life ofthe project are estimated at 20,000 kWh and $4,000.

4.6 ECM-6 Condensing Boiler Installation (Main Building)
The Main Building utilizes a hot water boiler to heat the building. The boiler is nearing the end of itsuseful life and is estimated to be approximately 75% efficient.
More efficient units, such as condensing boilers, provide efficiencies of approximately 93%. The energy saved is determined by comparing the difference in the energy used by the existing boiler and proposed condensing boiler for hot water heating.
Condensing boilers work on the principle of recovering as much waste heat as possible, which is normally ejected into the atmosphere from the flue of a conventional (non-condensing) boiler. This design maximizes the heat transfer from the burner and recovers useful heat which would normally be lost with the flue gases. When in condensing mode, (condensing boilers do not condense continually) the flue gases give up latent heat which is then recovered by the heat exchanger within the boiler. As a result, the temperature of the gases exiting the flue of a condensing boiler is typically 120-140°F.
This measure proposes replacing the existing boiler with one new 500 MBH condensing boiler in the same boiler room area. Modifications to the existing piping, electrical wiring, and flue stacks would also be required.
The condensing boiler has an expected life of 25 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 35,700 therms and $57,500.

4.7 ECM-7 Night Setback Controls (Main Building)
The Main Building’s HVAC systems are comprised of a mixture of programmable thermostats and temperature sensors for controlling space temperature. Existing thermostat settings are set to approximately 73 degrees. Temperature setback is not fully utilized. This measure proposes that 13 programmable thermostats be installed in place of the temperature sensors. The thermostats will be programmed for night setback of heating and cooling space temperatures, and would need to be secured such that occupants could not change the programmed night setback. Unoccupied heating temperature would be set at 55 degrees, and cooling temperature would be set at 80 degrees.
Programmage thermostats have an expected lifetime of 15 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 142,500 kWh, 16,500 therms and $48,000.

4.8 ECM-8 Electric Motors Replacement
Of the approximately 73 existing electric motors on the various STP process operations, 58 were identified to be suitable for replacement with higher efficiency units. This ECM evaluated replacing the existing standard efficiency and high efficiency motors with premium efficiency motors which are approximately 94.6% efficient. Motors with rated efficiencies greater than 93% and motors less than 1 HP in size were not considered for replacement. Efficiencies were obtained directly from nameplate data or from interviews with plant personnel. Savings were determined by comparing the energy usage of the existing motor to the energy usage of a premium efficiency motor. Based on discussions with plant personnel, the motors run at varying hours per year depending on the process; however, in general most operate continuously throughout the year.

4.9 ECM-9 Increase Rigid Roof Insulation (Main Building)
Rigid insulation is currently installed on the roof of the Main Building to provide thermal resistance. The total affected area is approximately 3,450 square feet. The roof is scheduled to be replaced, therefore this measure proposes adding 1” of rigid insulation to the existing 2” roof insulation to improve the energy efficiency of the building. The thermal resistance of rigid insulation is measured by the material’s R-value. Higher R-values represent higher resistance to temperature transfer. The existing 2” insulation has an R-value of R-10 and the proposed 3” insulation would have an R-value of R-15. Estimated budgetary cost for this measure is based on incremental cost of adding 1” of rigid insulation.
Insulation has an expected life of 30 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 6,000 kWh and $1,200.

5.0 POTENTIAL INCENTIVES
5.1 Incentives Overview
The Roxbury STP energy conservation project may be eligible for incentives by the New Jersey Office of Clean Energy. The largest incentives available will be for the New Jersey Pay for Performance (P4P) Program. The P4P program is designed for qualified energy conservation projects in facilities that consume a minimum annual peak electric demand of 200 kW per month (building is eligible if the demand in any of the preceding 12 months exceeds 200kW). Facilities that meet this criterion must also achieve a minimum performance target of 15% by using an approved simulation modeling tool before and after construction. To utilize this program, a P4P Partner would need to be engaged.
Incentives for the P4P program include the following:
Incentive #1: The P4P Program pays $0.05 per square foot to a maximum of $50,000 or 50% of building annual energy cost for the P4P Partner associated with development of an Energy Reduction Plan (ERP). This incentive is paid after approval of the ERP and signed Installation Agreement. Applicant must agree to commit to implementation of the ERP within 6 months or the incentive must be returned to the state.
Incentive #2: Paid after installation of recommended measures; base incentives deliver $0.11/kWh and $1.10/therm not to exceed 30% of total project cost.
Incentive #3: Paid after acceptance of Post-Construction Benchmarking Report showing energy savings over one year utilizing the approved simulation modeling tool and EPA Portfolio Manager. Incentive #3 base incentives deliver $0.07/kWh and $0.70/therm not to exceed 20% of total project cost.
Combining Incentives #2 and #3 will deliver a total of $0.18/ kWh and $1.80/therm not to exceed 50% of total project cost. Incentives for #2 and #3 are increased by $0.005/kWh and $0.05/therm for each percentage increase above the minimum performance target calculated with the approved simulation modeling tool, not to exceed 50% of total project cost.
A new incentive structure has been announced for projects exceeding 20% in energy savings utilizing the required EPA portfolio manager benchmarking tool. The new incentive structure will double incentives #2 and #3 therefore producing a total of $0.36/kWh and a $3.60/ therm for those projects exceeding 20%. Incentive #1 for application preparation and energy reduction plan development has not changed however the maximum incentive has now been raised to 80% of project costs. The 200 kW/month minimum annual peak electric demand has been dropped so any structure can apply. This incentive structure will be in effect until December 31, 2010.
Incentives are also available for prescriptive measures for various types of equipment under the New Jersey SmartStart Buildings incentive program. This program provides incentives dependent upon the existing equipment type and proposed equipment retrofit measure. Prescriptive measures under this program are paid after installation and no energy savings verification will be required. If applicable, incentives from this program are reflected in the ECM summaries and attached appendices. If the building qualifies and enters into the New Jersey P4P Program, all energy savings from recommended ECMs are included in the total building energy usage and savings to be applied towards the P4P incentive, including any ECMs that may have incentives available in the SmartStart Buildings program. A project is not applicable for incentives in both programs.
New Jersey BPU - Energy AuditsPage 17 of 25
5.2 Building Incentives
5.2.1 New Jersey P4P Program
The facility is not eligible for incentives under the New Jersey P4P Program. For the 7,600 square foot site, Incentive #1 corresponds to approximately $380. Since the overall energy reduction for the site is notestimated to exceed the 15% minimum, the facility is also not eligible for Incentives #2 and #3.
5.2.2 New Jersey SmartStart Buildings Program
The building is also eligible for incentives under the New Jersey SmartStart Buildings Program for the Lighting Replacements with Occupancy Sensors energy conservation measures (ECM-3), Roof Top Unit Replacement (ECM-5), Condensing Boiler Installation (ECM-6), and Electric Motor Replacement (ECM-8) suggested in this study. The total amount of all qualified incentives is about $10,800.
As noted previously, a project cannot apply for incentives from both the P4P Program and the SmartStart Buildings Program for the same project. See Appendix J for calculations.

6.0 ALTERNATIVE ENERGY SCREENING EVALUATION
6.1 Geothermal
Geothermal heat pumps (GHP) transfer heat between the constant temperature of the earth and the building to maintain the building’s interior space conditions. Below the surface of the earth throughout New Jersey the temperature remains in the low 50F range throughout the year. This stable temperature provides a source for heat in the winter and a means to reject excess heat in the summer. With GHPsystems, water is circulated between the building and the piping buried in the ground. The ground heat exchanger in a GHP system is made up of a closed or open loop pipe system. Most common is the closed loop in which high density polyethylene pipe is buried horizontally at 4-6 feet deep or vertically at 100 to 400 feet deep. These pipes are filled with an environmentally friendly antifreeze/water solution that acts as a heat exchanger. In the summer, the water picks up heat from the building and moves it to the ground. In the winter the system reverses and fluid picks up heat from the ground and moves it to the building. Heat pumps make collection and transfer of this heat to and from the building possible.
The Roxbury STP Main Building has all required heating provided by a natural gas fired Weil McLainhot water boiler serving hot water unit heaters as well as finned tube baseboard radiation. Cooling is facilitated with one RTU. To take advantage of a GHP system, the building would have to install a low temperature closed loop water source heat pump system as well as vertical bore field to realize the benefit of the consistent temperature of the ground. This will also include the removal of the existing heating and cooling system.
This measure is not recommended due to the high cost to replace the existing systems.
6.2 Solar
6.2.1 Photovoltaic Rooftop Solar Power Generation
The building was evaluated for the potential to install rooftop photovoltaic (PV) solar panels for power generation. Present technology incorporates the use of solar cell arrays that produce direct current (DC) electricity. This DC current is converted to alternating current (AC) with the use of an electrical device known as an inverter. The building’s roof has sufficient room to install a large solar cell array. A structural analysis would be required to determine if the roof framing could support a cell array.
The PVWATTS solar power generation model was utilized to calculate PV power generation. The New Jersey Clean Power Estimator provided by the New Jersey Clean Energy Program is presently being updated; therefore, the site recommended use of the PVWAT solar grid analyzer version 1. The closest city available in the model is Newark, New Jersey and a fixed tilt array type was utilized to calculate energy production. The PVWAT solar power generation model is provided in Appendix K.
The State of New Jersey incentives for non-residential PV applications is $1.00/watt up to 50 kW of installed PV array. Federal tax credits are also available for renewable energy projects up to 30% of installation cost. Municipalities do not pay federal taxes; therefore, would not be able to utilize the federal tax credit incentive.
Installation of (PV) arrays in the state New Jersey will allow the owner to participate in the New Jersey solar renewable energy certificates program (SREC). This is a program that has been set up to allow entities with large amounts of environmentally unfriendly emissions to purchase credits from zero emission (PV) solar-producers. An alternative compliance penalty (ACP) is paid for by the high emission
New Jersey BPU - Energy AuditsPage 19 of 25
producers and is set each year on a declining scale of 3% per year. One SREC credit is equivalent to 1000 kilowatt hours of PV electrical production; these credits can be traded for period of 15 years from the date of installation. The cost of the ACP penalty for 2009 is $689; this is the amount that must be paid per SERC by the high emission producers. The expected dollar amount that will be paid to the PV producer for 2009 is expected to be $600/SREC credit. Payments that will be received from the PV producer will change from year to year dependent upon supply and demand. Renewable Energy Consultants is a third party SREC broker that has been approved by the New Jersey Clean Energy Program. As stated above there is no definitive way to calculate an exact price that will be received by the PV producer per SREC over the next 15 years. Renewable Energy Consultants estimated an average of $487/ SERC per year and this number was utilized in the cash flow for this report.
The Roxbury STP had a maximum kW demand of 364 kW over the previous 12 months. The monthly average over the observed 12 month period was 269 kW. The facility’s existing load should justify the use of the maximum incentive cap of 50 kW of installed PV solar array; therefore, a 50 kW system size was selected for the calculations. The system costs for PV installations were derived from the most recent NYSERDA (New York State Energy Research and Development Agency) estimates of total cost of system installation. It should be noted that the cost of installation is currently $10 per watt or $10,000 per kW of installed system. This has increased in the past few years due to the rise in national demand for PV power generator systems. Other cost considerations will also need to be considered. PV panels have an approximate 20 year life span; however, the inverter device that converts DC electricity to AC has a life span of 10 to 12 years and will need to be replaced multiple times during the useful life of the PV system.

This measure is not recommended at this time due to the long payback period; however, it could be a potentially viable renewable measure to be considered in the future if electricity rates continue to increase and if PV installation costs decline below $10 per watt.
6.2.2 Solar Thermal Domestic Hot Water Plant
Active solar thermal systems use solar collectors to gather the sun’s energy to heat water, another fluid, or air. An absorber in the collector converts the sun’s energy into heat. The heat is then transferred by circulating water, antifreeze, or sometimes air to another location for immediate use or storage for later utilization. Applications for active solar thermal energy include providing hot water, heating swimming pools, space heating, and preheating air in residential and commercial buildings.
A standard solar hot water system is typically composed of solar collectors, heat storage vessel, piping, circulators, and controls. Systems are typically integrated to work alongside a conventional heating system that provides heat when solar resources are not sufficient. The solar collectors are usually placed on the roof of the building, oriented south, and tilted around the site’s latitude, to maximize the amount of radiation collected on a yearly basis.
New Jersey BPU - Energy AuditsPage 20 of 25
Several options exist for using active solar thermal systems for space heating. The most common method involves using glazed collectors to heat a liquid held in a storage tank (similar to an active solar hot water system). The most practical system for the site would transfer the heat from the panels to thermal storage tanks and transfer solar produced thermal energy to use for domestic hot water production.
As of the writing of this report, there are no incentives available for installation of thermal solar systems. Presently there is a federal tax credit of 30% of installation cost for the thermal applications, however the Township of Roxbury does not pay federal taxes and, therefore, would not benefit from this program.
The facility has limited occupancy and one bath room sink. Due to low hot water use this measure is not recommended.
This measure is not recommended.
6.3 Wind
Small wind turbines use a horizontal axis propeller, or rotor, to capture the kinetic energy of the wind and convert it into rotary motion to drive a generator which usually is designed specifically for the wind turbine. The rotor consists of two or three blades, usually made from wood or fiberglass. These materials give the turbine the needed strength and flexibility, and have the added advantage of not interfering with television signals. The structural backbone of the wind turbine is the mainframe, and includes the slip-rings that connect the wind turbine, which rotates as it points into changing wind directions, and the fixed tower wiring. The tail aligns the rotor into the wind.
To avoid turbulence and capture greater wind energy, turbines are mounted on towers. Turbines should be mounted at least 30 feet above any structure or natural feature within 300 feet of the installation. Smaller turbines can utilize shorter towers. For example, a 250-watt turbine may be mounted on a 30-50 foot tower, while a 10 kW turbine will usually need a tower of 80-120 feet. Tower designs include tubular or latticed, guyed or self-supporting. Wind turbine manufacturers also provide towers.
The New Jersey Clean Energy Program for small wind installations has designated numerous pre-approved wind turbines for installation in the State of New Jersey. Incentives for wind turbine installations are based on kilowatt hours saved in the first year. Systems sized under 16,000 kWh per year of production will receive a $3.20 per kWh incentive. Systems producing over 16,000 kWh will receive $51,200 for the first 16,000 kWh of production with an additional $0.50 per kWh up to a maximum cap of 750,000 kWh per year. Federal tax credits are also available for renewable energy projects up to 30% of installation cost for systems less than 100 kW. However, as noted previously, municipalities do not pay federal taxes and are, therefore, not eligible for the tax credit incentive.
The most important part of any small wind generation project is the mean annual wind speed at the height of which the turbine will be installed. In the Roxbury New Jersey area, the map indicates a mean annual wind speed of below 10 miles per hour. For the building, there are site restrictions. Parking lots, radio communication towers, trees, and local residential housing would greatly affect a tower location. A wind speed map is included in Appendix L.
This measure is not recommended due to the low mean annual wind speed.
6.4 Combined Heat and Power Generation (CHP)
Combined heat and power, cogeneration, is self-production of electricity on-site with beneficial recovery of the heat byproduct from the electrical generator. Common CHP equipment includes reciprocating
New Jersey BPU - Energy AuditsPage 21 of 25
engine-driven, micro turbines, steam turbines, and fuel cells. Typical CHP customers include industrial, commercial, institutional, educational institutions, and multifamily residential facilities. CHP systems that are commercially viable at the present time are sized approximately 50 kW and above, with numerous options in blocks grouped around 300 kW, 800 kW, 1,200 kW and larger. Typically, CHPsystems are used to produce a portion of the electricity needed by a building some or all of the time, with the balance of electric needs satisfied by purchase from the grid.
Any proposed CHP project will need to consider many factors, such as existing system load, use of thermal energy produced, system size, natural gas fuel availability, and proposed plant location.
The Roxbury STP has sufficient need for electrical generation and the ability to use most of the thermal byproduct during the winter. Thermal usage during the summer months is low, and thermal energy produced by the CHP plant will be wasted. An absorption chiller could be installed to utilize the heat to produce chilled water; however, there is no chilled water distribution system in the building.
A potential source of energy capture at the Roxbury Township STP is at the sludge thickening stage. Several processes throughout the plant generate solid waste. These are pumped manually to the sludge thickener. As the sludge becomes dewatered, the decomposition of the solids generates methane gas as a by-product of sludge digestion. This gas can potentially be captured and utilized for generation of electric energy at the plant. The most viable option for a CHP plant would be a micro-turbine methane gas-fired unit. However, based on discussions with plant personnel, major modifications to any of the treatment units would significantly impact the plant’s ability to operate continuously. Therefore this option is not viable at this time.
This measure is not recommended due to the impact to daily plant operations, and limited use of summertime heat.
6.5 Biomass Power Generation
Biomass power generation is a process in which waste organic materials are used to produce electricity or thermal energy. These materials would otherwise be sent to the landfill or expelled to the atmosphere. To participate in NJCEP's Customer On-Site Renewable Energy program, participants must install an on-site sustainable biomass or fuel cell energy generation system. Incentives for bio-power installations are available to support up to 1MW-dc of rated capacity.
*Class I organic residues are eligible for funding through the NJCEP CORE program. Class I wastes include the following renewable supply of organic material:
Wood wastes not adulterated with chemicals, glues or adhesives Agricultural residues (corn stover, rice hulls or nut shells, manures, poultry litter, horse manure,
etc) and/or methane gases from landfills Food wastes Municipal tree trimming and grass clipping wastes Paper and cardboard wastes Non adulterated construction wood wastes, pallets
The NJDEP evaluates biomass resources not identified in the RPS.
Examples of eligible facilities for a CORE incentive include:
New Jersey BPU - Energy AuditsPage 22 of 25
Digestion of sewage sludge Landfill gas facilities Combustion of wood wastes to steam turbine Gasification of wood wastes to reciprocating engine Gasification or pyrolysis of bio-solid wastes to generation equipment
* from NJOCE Website
This measure is not recommended because the site does not have room to store the waste organic materials, noise issues, and potential zoning issues.
6.6 Demand Response Curtailment
Presently, the Roxbury STP has electricity delivered and supplied by Jersey Central Power and Lighting Corporation (JCP&L). Utility curtailment is an agreement with the regional transmission organization and an approved Curtailment Service Providers (CSP) to shed electrical load by either turning major equipment off or energizing all or part of a building utilizing an emergency generator, therefore reducing the electrical demand on the utility grid. PJM is the regional transmission organization (RTO) that coordinates the movement of wholesale electricity in all or parts of 13 states and the District of Columbia including the State of New Jersey.
This program is to benefit the utility company during high demand periods and PJM offers incentives to the CSP to participate in this program. Enrolling in the program will require program participants to drop electrical load or turn on their emergency generators during high electrical demand conditions or during emergencies. Part of the program also will require that program participants reduce their required load or run their emergency generators with notice to test the system. A minimum of 100 kW of curtailable load is required to enter the program. Discussions with the EnerNoc Corporation, an approved CSP, indicate that existing emergency generators will not pass the emissions requirements to enter the program.
Presently, The Roxbury STP has 400 kW back up generation and an average kW demand during the observed period of 269 kW per month. The bulk of the electricity usage is needed during any request to reduce electrical load due to the 24 hour seven day a week.
This is not recommended because the emergency generator for the facility cannot meet air emissions standards in the State of New Jersey and the building load cannot be substantially reduced during a planned Demand Response Curtailment event.
New Jersey BPU - Energy AuditsPage 23 of 25
7.0 EPA PORTFOLIO MANAGER
The United State Environmental Protection Agency (EPA) is a federal agency in charge of regulating environment waste and policy in the United States. The EPA has released the EPA Portfolio Manager for public use. The program is designed to allow property owners and managers to share, compare and improve upon their building’s energy consumption. Inputting such parameters at electricity, heating fuel, building characteristics and location into the website based program generates a naturalized energy rating score out of 100. Once an account is registered, monthly utility data can be entered to track the savings progress and retrieve an updated energy rating score on a monthly basis.
The facility includes STP process equipment and an office area, and is considered a high energy consumer per the Portfolio Manager with a Site Energy Usage Index (EUI) of 5 kBTU/gal/day. Several factors contribute to the unfavorable EUI, including inefficient motors, inefficient lighting operation, etc. By implementing the measures discussed in this report, it is expected that the EUI can be reduced to approximately 4 kBTU/gal/day.
A full EPA Energy Star Portfolio Manager Report is located in Appendix M. The user name and password was provided to Valarie Wyble, Executive Assistant, Township of Roxbury.

8.0 CONCLUSIONS & RECOMMENDATIONS
The energy audit conducted by CHA at the Roxbury Township Ajax Terrace Sewer Treatment Plant located in Succasunna, New Jersey identified potential ECMs for lighting upgrades with occupancy sensors, door seal replacement, condensing boiler installation, night setback, and premium motors. Potential annual savings of $27,200 may be realized for the recommended ECMs, with a summary of the cost, savings, and payback as follows:

Average InfluentFlow
2 MGD (million gallons perday)
Is this the daily average actual flow of wastewaterinto the facility, measured in million gallons perday (MGD)? The average flow is likely to vary overtime; this figure should reflect an annual averageinfluent flow.
Average InfluentBiological Demand
(BOD5)Concentration
200 mg/l (milligrams perliter) (Default)
Is this the average biological demandconcentration of the wastewater flowing into thefacility? This should be the average concentrationestimated over a 12 month period. BOD5 shouldbe reported in mg/l. BOD5 is not the same asCBOD5, the carbonaceous biological oxygendemand. BOD5 is required for the energyperformance rating.
Average EffluentBiological Demand
(BOD5)Concentration
8 mg/l (milligrams per liter)(Default)
Is this the average biological demandconcentration of the wastewater after it is treatedand is leaving the facility? This should be theaverage concentration estimated over a 12 monthperiod. BOD5 should be reported in mg/l. BOD5 isnot the same as CBOD5, the carbonaceousbiological oxygen demand. BOD5 is required forthe energy performance rating.
Plant Design FlowRate
2 MGD (million gallons perday)
Is this the plant design flow rate, measured inmillion gallons per day (MGD)? This is the amountof flow the plant is designed to process.
Fixed Film TrickleFiltration Process No
Does this facility have an onsite fixed film tricklefiltration process? Trickle filtration is a processused to reduce BOD, pathogens, and nitrogenlevels.
