Teaneck Board of Education Energy Savings Plan

SECTION 1. EXECUTIVE SUMMARY

Various energy conservation measures were evaluated in the development of this Energy Savings Plan (ESP). Energy Systems Group has performed field verifications, collected data and taken field measurements to ensure the development of the most cost-effective solutions as well as accurate savings calculations. Various solutions were reviewed with the school district’s administration to develop a set of Energy Conservation Measures (ECMs) that allow the school district to address the facility’s priority items while reducing the total annual energy spend for the District. This study expands upon the original energy audit conducted by Camp Dresser and McKee (CDM). The original audit information was used for building descriptions as well as an overall indication of the District’s needs.

Priority items include:

▪ Comprehensive LED Lighting Upgrades

▪ Replace Rooftop Cooling Unit at Whittier Elementary School ▪ Unit Ventilator Replacement at Teaneck High School
▪ Boiler Room Upgrade/ Replacement at Teaneck High School

Energy Savings

Energy saving calculations performed in the development of this ESP was completed using Microsoft Excel worksheets with Bin weather data to accurately model the building systems. Additional spreadsheets were used for measures that are not affected by the weather, such as lighting savings. Energy savings have been provided electronically for ease of review. All the energy savings calculations that have been performed are in accordance with the New Jersey Clean Energy Program Protocols to Measure Resource Savings.

Benefits

The measures investigated in this EnergySavings Plan could result in an annual utility savings of 1,697,814 kWh’s of electricity and save 100,381 therms of natural gas. The total utility cost savings is $7,544,068 over the life of the project (19 years). Additionally, these energy savings will result in a net reduction of greenhouse gases and will reduce the school district’s carbon footprint by 3,507,204 lbs. of CO2 annually. All these savings are achieved while improving the classroom environment and renewing many items that have been in service beyond useful life expectancy

Marginal Rates

For the purposes of determining how energy conservation measures will affect the utility bill, it is important to understand what portions of the cost can be saved. In general, there are costs associated with utility bills that are fixed and independent of usage, such as the monthly meter charge. For example, in the case of a monthly meter charge, this charge often exists even if the energy usage were zero. An energy conservation measure often cannot produce a cost savings on this portion of the bill. The utility rate structure must, therefore, be analyzed to determine what portion of the bill a cost savings can be produced using a specific energy conservation measure. For the purposes of this report, the blended average utility rate is the total cost divided by the total energy units. The effective rate is the portion of the bill effected by energy saving or the applied energy conservation measure.

The utility rates identified below were used for purposes of calculating the dollar effect of the energysavings for the district.

Electric

The effective supply kWh rate is the most recent in the baseline period. The effective transport $/kWh and $/kW demand rates are based on the most recent utilitytariff rates as of 0612/17. The total effective $/kWh rate is the summation of the supply and transport effective rates. For simplification an Average Effective $/kWh rate was determined by averaging the summer and annual effective $/kWh rates and is used for calculations. Summer rate is considered months June through September. The total summer billed demand rate is the annual demand rate plus the summer demand rate. Rates shown include New Jersey Sales and Use Tax (SUT). A simplified weighted average $/kW demand is used as the effective rate for savings calculations. It was calculated by taking the summation of the annual $/kW demand times 8/12 plus the total summer $/kW demand times 4/12.

Teaneck Board of Education Energy Savings Plan

Natural Gas

Due to the complex nature and variablity of the gas rates which includes demand and balancing charges in the tarriff rates the effective rate is considered for savings calculations. In cases where more than one account/meter serves a school the total average of all combined accounts is used unless the account is not significant, for instance where the account exists but delivers no natual gas on a regual basis or uses a very small amount relative to the other accounts.

Operational Savings Estimates

The lighting retrofits recommended for this project will reduce the number of lamps that need to be replaced each year due to the longer lasting lamps and new technology fixtures. The LED lighting recommended for the exterior fixtures will last much longer than the current high intensity discharge (HID) lighting and will generate material cost savings.

A brief description of the operational savings estimated for this project is included below. Energy Systems Group has worked with the District to quantify the exact sources of savings by going through past invoices and expenses. The operational savings will not be escalated.

SECTION 4. ENERGY CONSERVATION MEASURES

1-1 Comprehensive LED Lighting Upgrades ECM Summary

Lighting Retrofit and Replacement: Most of the lighting fixtures throughout Teaneck Public Schools, utilize older technologies that can be upgraded. Improvements to lighting will reduce electrical consumption and improve lighting levels. The costs of material to maintain the current systems will also be reduced since these renovations replace items (i.e., lamps and ballasts) that are near the end of their life cycle and/or considered environmentally hazardous.

Where appropriate, lighting levels will be adjusted to meet Illumination Engineering Society (IES) standards.

Lighting Levels: Our proposed lighting system improvements will maximize savings while maintaining or improving existing light levels in each area. All installations will complywith IES standards. Post-retrofit light levels are typically increased because of the improved design and installation of newer equipment, but areas that are currently over lit will be adjusted to maintain IES recommended light level. Before and after sample light level reading will be performed to confirm expected results.

Exterior Lighting: In an effort to reduce electricity consumption and provide better security for Teaneck Public School buildings, ESG is proposing to retrofit the existing outside lighting (excludes parking lots) on the buildings with newer, LED technology with photocells for automatic control. In addition, every effort will be made to standardize the installed components for equipment uniformity and maintenance simplicity. Typical LED lighting system exhibit the following characteristics:

•	Extremely Long Life – up to 50,000+ hours
•	Highly efficient with very low wattage consumption
•	Solid state lighting technology ensures that the fixtures are highly durable

Lighting Controls: Lighting controls are effective in areas where lighting is left on unnecessarily, mainly because it is a common area or due to 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. 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.	No Occupancy/Vacancy sensors were included in this project, due to poor economics.

Facilities Recommended for this Measure

•	Teaneck High School

Scope of Work

Because the Teaneck High School does not qualify for Direct Install Program incentives, Energy Systems Group recommends retrofitting the lighting system with new LED technology lamps. The retrofit process includes the removal of existing components of fluorescent technology including lamps, ballast(s), and tombstones. If the lens of the existing fixture is cracked or discolored, ESG will recommend replacement of this component as well. ESG recommends replacing the fluorescent technology components with new LED technology components - Direct wired Type – B LED T8 Tube and tombstone replacement.

There was no recommendation for upgrade to the metal halide and quartz downlights in the Auditorium space. Unfortunately, no cost effective options are available that will work with the existing dimming system. In order to replace these lights with an energy saving lower wattage technology, the existing dimming system will need to be replaced with a compatible dimming system. This option is not a cost effective solution for the project.

Any classrooms with bi-level switching will be converted to a checkerboard pattern, rather than two levels within each fixture.

Any existing LED fixtures will remain and not be replaced.

Energy Systems Group included (54) Fifty Four “1200 Lumen Constant Wattage Emergency Back-up LED Strip” in existing egress fixtures to provide illumination during a power loss.

Refer to Line by Line inventory included in the appendix for comprehensive fixture list.

Savings Methodology

In general, savings calculations for lighting retrofits are calculated using the following methodology:

Maintenance

Lighting will need to be replaced in order to provide consistent light quality throughout the exterior space. It is recommended to conduct group re-lamping on regularly scheduled intervals in order to minimize maintenance requirements.

Benefits

▪ Electrical energy savings

▪ Improved exterior light quality

▪ Reduction in maintenance of exterior lighting system ▪ Improved safety around school perimeter
▪ Reduced lamp replacement for 5 to 10 years for LEDs

1-3 Install VFD’s and Premium Motor Upgrades for HVAC ECM Summary

This measure will replace constant volume pumping systems with a variable flow system through the installation of Variable FrequencyDrive(s) (VFD) on electricmotor(s)for hot water pumps, where prudent. Constant volume systems are equipped with a differential pressure sensor and bypass valve that diverts water not being used at the terminal units back to the pump inlet.While this enables the system to properly control flow at the units, the central pumps continually operate at full speed/flow. Varying the speed of a motor to match the actual load at the terminal units reduces the pumps electrical motor power (kW), which results in significant electrical energy savings.

Any single speed or two speed inverter-duty pump motor (typically greater than 5 to 10 HP) that has fluctuating loads is a good candidate for a variable speed drive. Heating hot water pumps are ideal candidates for VFD control due to the varying loads on building heating demand and motors which are typically larger than 10 HP.

Facilities Recommended for this Measure

•	Teaneck High School

Scope of Work by School

2-4 Refrigeration Controls ECM Summary

The kitchens throughout Teaneck District Schools contain walk-in freezers, walk-in coolers, reach-in freezers and reach-in coolers. These units are controlled bya drybulb temperature and as a result run continuously throughout the year. Installing an NRM Cooltrol® retrofit was assessed. The refrigeration systems usually monitor circulating air temperature in order to decide when to switch on and off. The circulating air temperature tends to rise far more quickly than the food temperature, and as result, the refrigeration unit works harder than necessary to maintain stored products at the right temperature. This, in turn, leads to excessive electricity consumption and undue wear and tear on the equipment. With NRM Cooltrol®, the thermostat regulates the refrigeration temperature based upon product temperature rather than air temperature,	thereby maintaining	product	at	the	proper temperature. Savings is a result of reduced frequency of the compressor cycles, which are now based on food temperature rather than volatile air temperature. The equipment present in the schools are shown in the table below.

2-5/2-7 Direct Install Program Fuel Use Economizers ECM Summary

A heating system must be able to provide acceptable comfort at the lowest anticipated outdoortemperature. Most commercial/industrial boilers have a heating capacity 1.5 to 2 times larger than needed to maintain space temperature on extreme days. Due to this oversizing of the boiler, the burner will cycle on and off to prevent overheating of the system water during any call for heat.

Intellidyne Heating System Economizers increase system efficiency, thus, the heating system uses less fuel to generate the same amount of heat. This is done by dynamically changing the aquastat's effective dead-band based on the measured heating load. This causes the average water temperature to be varied (depending on the measured load) and is accomplished by extending the burner's off-time. Extending the off-time also results in longer, more efficient burns and a reduction in burner cycling. Just as computer control has increased the gas mileage of automobiles, Intellidyne Heating System Economizers improve the fuel utilization of heating systems by supplementing the antiquated on/off control action of the aquastat with the analysis and control capabilities of a computer.

4-1 Condensing Hot Water Boiler Plant (Teaneck High School – Fan Room Upgrades)

ECM Summary

Steam boilers are used to provide heating, through the use of a hot water heat exchanger, to various areas throughout the building. In schools where the boilers are old and in a poor condition, the replacement of existing boilers with a similar output of new greater efficiency units will provide efficiency gains that will generate operating and fuel cost savings. The radiant and convective heat losses will also be reduced with the installation of new boilers which makes the entire hot water system more efficient. Where applicable, the steam boilers that are recommended for replacement will be replaced by condensing boilers with increased efficiencies (including thermal and combustion losses).

The replacement of the single boiler in these boiler plants with multiple new high-efficiency units will generate significant energy savings as well as provide redundancy to the heating system. Each new boiler will be slightly smaller than the existing boilers,but as a whole central plant will exceed the heating efficiency of the current boiler system. The installation of the smaller boilers will increase the efficiency of the entire plant by operating more efficiently at low loads than the existing boilers.

4-3 Replace Steam Traps ECM Summary

Mechanical traps are prone to failure as they age, resulting in large steam losses and requiring substantial maintenance. Steam traps separate the steam system from the condensate system.Traditional steam traps can fail in the open or closed position. When a steam trap fails in the open or leaking-by position, some or all of the energythatwas added at the boilerislostinto the condensate return system.The energy contained in steam is only utilized when it condenses in a heat exchanger (radiator, convector, hot water heater, AHU coil, etc.) and releases its latent heat to the process. It is at this point the steam trap should allow this condensate into the condensate return system to return to the boiler. As mentioned above, a leaking trap still allows steam to flow through the heat exchange device it serves and will typically not affect its heating capacity. For this reason, leaking traps are rarely discovered without performing specific tests on the trap. Conversely, a steam trap that fails in the closed position does not allow the condensate to enter the condensate return system. As a result, condensate backs up into the heat exchange device it serves, thereby first reducing, then eliminating, its heating capacity. Plugged traps are often identified through “cold calls” and repaired. Replacing or repairing failed traps will improve the efficiency of the steam distribution system and save energy.

Facilities Recommended for this Measure

•	Bryant Elementary School

•	Hawthorne Elementary School

•	Lowell Elementary School

•	Whittier Elementary School

Scope of Work

•	All mechanical traps identified in the steam trap audit will be replaced with new traps

•	In many instances it was difficult to confirm size, make and model of the various thermostatic traps inside radiator and convector enclosures due to the cover itself and accumulated dust and debris. This information should be confirmed before ordering any model specific parts.

Detailed drawings of the trap locations for each building is provided in Appendix 4.

Teaneck Public Schools Energy Savings Plan

Savings Methodology

Savings are calculated using the following methodology:

Steam trap losses depend on the steam pressure and temperature, the type of trap, orifice size, and the level of leakage through the failed trap. Steam losses are calculated based on the amount of steam lost through the trap. Failed closed or “plugged” traps are unique in that there is no steam lost through the trap itself. Steam traps are important in the steam system to remove the condensate from the system. If the condensate is not removed from the steam system, the system loses efficiency. In some cases, a steam trap that is failed closed will cause an excessive buildup of condensate and could cause a blockage of steam flow.

Steam trap losses for leaking traps are calculated using the following modified Napier formula:

Periodically the equipment should be checked to ensure proper operation.

5-3 Refurbish Cooling Tower ECM Summary

As cooling towers age, their efficiency decreases due to dirt, corrosion and scale impairing heat transfer. Leaks and evaporative losses cause the cooling tower to use more water and the cooling energyassociated with it. ESG proposes to coat the cooling tower to provide a flexible barrier to seal all of the seams for the cooling tower.

Additionally, variable frequency drives (VFDs) are used to control the fan speed of cooling towers in correlation with the outside air temperature. This allows for the optimal efficiency of cooling tower water and saves electric energy. ESG proposes to repair/recommission the current non-functioning VFDs installed on the cooling tower fan.

Facilities Recommended for this Measure

•	Teaneck High School

Scope of Work

Cooling Tower Coating

•	Remove and save fill.

•	Clean the exterior and interior of the cooling tower. •	Sandblast/grind pan to remove any scale.
•	Coat entire pan with polyurea to stop leak and protect from future leaks.

•	Re-install original fill. Any material that is damaged during process will be replaced with new.

7-1 Building Envelope Weatherization ECM Summary

Infiltration drives energy costs higher by allowing unconditioned outside air to enter the building, thus adding to the building load and causing additional unnecessary heating and cooling loads. Teaneck School District buildings were surveyed in order to identify potential improvements for outside air infiltration reduction. The main observations are listed below:

▪ Most entrance doors need weather stripping, sweeps or the closure or strike plate adjusted; ▪ Sealant is recommended around the perimeter of several windows;

▪ Numerous penetrations were observed that need to be sealed.

These deficiencies mostly reflect the skin of the buildings, which either have existed since original construction of the building, were added during some retrofit periods, or were caused by deterioration.

Detailed findings from the audit are located in the appendix.

Facilities Recommended for this Measure

•	Benjamin Franklin Middle School •	Bryant Elementary School
•	Whittier Elementary School

•	Hawthorne Elementary School

•	Lowell Elementary School •	Teaneck High School
•	Thomas Jefferson Middle School

Scope of Work

A building envelope audit was performed for the entire district. The results of the audit were the identification of several areas of envelope deficiency. The deficient areas were tabulated and their savings potential calculated.

Building Envelope Scope drawings and recommendations are listed in the Appendices.

Savings Methodology

The physics of air leakage guide the requirements for the design of an effective air leakage control retrofit project.

•	Big Holes = Area

Sealing big holes and/or a lot of small holes generates savings. •	Big Pressure Differentials = ΔP
Sealing surfaces that have the highest pressures acting on them generates savings: at the top and bottom of the building (stack pressure), spaces that are pressurized or depressurized (mechanical pressure) and surfaces that are most exposed to the elements (wind pressure).
•	Big Temperature Differentials = ΔT or HDD

Sealing interior-to-exterior air leakage pathways generates savings. Isolating interior spaces (or compartmentalizing) is effective only across interior spaces with very different interior environment needs.

Thermal Upgrade

ESG uses standard heat loss calculations (U, A, ΔT) to estimate savings from thermal barrier improvements.

As with air leakage, the physics of thermal heat loss guide the requirements for the design of an effective energy saving insulation upgrade project.
•	Weak Existing Insulation Values: U-Value

Insulating surfaces with the weakest existing insulation values generates savings. •	Big Surface Areas: Area
Insulating large surface areas generates savings. •	Big Temperature Differentials: ΔT or Degree Days

Insulating interior-to-exterior surfaces (attic surfaces are included in this category) generates savings. Isolating interior surfaces (or compartmentalizing) is effective only across interior spaces with very different interior environment needs.

Maintenance

After the building envelopes have been improved, operations and maintenance should be reduced, due to improved space conditions and lower humidity during the cooling season. The maintenance staff should maintain the newly installed equipment per manufacturers’ recommendations. The manufacturer specification sheets will be provided for exact maintenance requirements.

7-3 RepairMissing Pipe Insulation ECM Summary

Non-insulated pipelines and associated valves and fittings carrying thermal fluids because heat loss where not intended and result in excess fuel consumption, as well as discomfort in occupied areas. Valves and fittings without insulation were observed throughout the buildings and installation of new insulation is recommended. Installation of the proper amount of insulation will not only conserve energy but will also improve safety by reducing the chance for burns on hot piping or slipping due to condensate on a pipe. This ECM would insulate bare and poorly insulated heating hot water piping and failed heating hot water piping insulation in the boiler room.

Findings

•	 Pipe Insulation – un-insulated pipes in the steam, condensate, and heating and hot water systems are leading to unnecessary distribution losses and wasted energy.
•	 Valve & Fitting Insulation – valves and fittings are difficult components of a mechanical system to insulate and as a result are frequently left un-insulated. These un-insulated or poorly insulated components have the same temperature fluids passing through them as the pipes that are more likely to be insulated; un-insulated components of the distribution system lead to unnecessary distribution losses and wasted energy.
•	 Tank Insulation – tanks are difficult components of a mechanical system to insulate and as a result are frequently left un-insulated. Un-insulated or poorly insulated tanks or equipment have the same temperature fluids passing through them as the pipes that are more likely to be insulated; un-insulated components of the distribution system lead to unnecessary distribution losses and wasted energy.

Savings Methodology

Mechanical Insulation Savings Calculations

This section describes our methodology for calculating energy savings. We use standard heat transfer methods to compute heat loss from bare and insulated mechanical systems (piping, valves, fittings, tanks and ductwork). The difference in heat loss is the energy savings, as follows:

Energy Savings = [Existing Heat Loss] – [Insulated Heat Loss]

Methodology

We use standard heat transfer methods to compute radiation, convection, and conduction heat loss from

(Alternatively, gain to, for cold systems) bare and insulated systems. Key parameters that affect the heat transfer rate include: temperature of fluid (e.g. steam, hot water, chilled water, etc.); surface temperature of the component (e.g. pipe, fitting, tank, ductwork); temperature of environment; emissivity of surface; average wind speed where applicable; percentage of existing component covered with insulation; and condition of existing insulation, where applicable.

Energy Usage

Existing and proposed energy use are computed as follows:

Pipes & Fittings

Heat Loss (Btu/h) = (Heat Loss / lin.ft. bare pipe) * (lin.ft. of pipe) * [1 – (%insulated)] + (Heat Loss / lin.ft. insulated pipe) * (lin.ft. of pipe) * (%insulated)

Fuel Loss (MMBTU/yr) = (Heat Loss Btu/h) * (heating hrs/year) ÷ (efficiency)
Electric Loss (kWh/yr) = (Heat Loss Btu/h) * (cooling hrs/year) ÷ (12,000 Btu/ton-hr) x (cooling kW/ton)

Tanks, Plates, & Ductwork

Existing and proposed heat loss for tanks, plates, and ductwork are calculated as follows:

Heat Loss (Btu/h) = (Heat Loss / sq.ft.) * (sq.ft. of component) * (qty) * [1 – (%insulated)] + (Heat Loss / sq.ft. insulated) * (qty) * (sq.ft. of component) * (%insulated)

Fuel Loss (MMBTU/yr) = (Heat Loss Btu/h) * (heating hrs/year) ÷ (efficiency)

Electric Loss (kWh/yr) = (Heat Loss Btu/h) * (cooling hrs/year) ÷ (12,000 Btu/ton-hr) x (cooling kW/ton)

Energy Savings

Energy savings are the difference between existing and proposed heat loss:

Fuel Savings (MMBTU/yr) = (Existing Fuel Loss) – (Proposed Fuel Loss)

Electric Savings (MMBTU/yr) = (Existing Electric Loss) – (Proposed Electric Loss)

Cost Savings ($/yr) = (Fuel Savings MMBTU/yr) * (Fuel Rate $/MMBTU) + (Electric Savings kWh/yr) * (Electric Rate $/kWh)

Heat Transfer: Bare Systems

Bare systems are subject to convection and radiation heat transfer. We ignore conductive heat transfer through the pipe/fitting material (e.g. steel, copper, PVC etc.) as this is negligible as compared to heat transfer through insulation and air convection.

Pipes & Fittings

This section describes the heat transfer calculations for pipes and fittings for indoor systems subject to natural convection (no wind). The calculations for outdoor systems subject to forced convection (wind) are similar except that the formulas are more complicated. These methods are presented following this section.

For fittings (valves, elbows, strainers, etc.), we estimate heat loss based on equivalent length of straight pipe, which is the ratio of the area of the fitting to the area of 1 linear foot of pipe of the same size (fitting equivalent length = Area of fitting, ft2 / Area of pipe of equivalent diameter, ft2).

Heat Transfer: Insulated Systems

Insulated systems are subject to convection, radiation, and conductive heat transfer. We ignore conductive heat transfer through the pipe/fitting material (e.g. steel, copper, PVC etc.) as this is negligible when compared to heat transfer through insulation and air convection.

SECTION 5. MEASUREMENT AND VERIFICATION

Measurement & Verification (M&V) Methodologies

This section contains a description of the types of Measurement and Verification (M&V) methodologies that Energy Systems Group will use to guarantee the performance of this project.

They have been developed and defined by two independent authorities:

▪ International Performance Measurement and Verification Protocol (IPMVP) ▪ Federal Energy Management Program (FEMP)

There are four guarantee options that may be used to measure and verify the performance of an energy conservation measure. Each one is described below.

Option A – Retrofit Isolation: Key Parameter Measurement

Energy savings is determined by field measurement of the key parameters affecting the energy use of the system(s) to which an improvement measure was applied separate from the energy use of the rest of the facility. Measurement frequency ranges from short-term to continuous, depending on the expected variations in the measured parameter, and the length of the reporting period.

Measurement of key parameters means that those parameters not selected for field measurement will be estimated. Estimates can be based on historical data, manufacturer’s specifications, or engineering judgment. Documentation of the source or justification of the estimated parameter will be described in the M&V plan in the contract. Energy savings is determined through engineering calculations of the baseline and post-retrofit energy used based on the combination of measured and estimated parameters, along with any routine adjustments.

Option B – Retrofit Isolation: All ParameterMeasurement

Like Option A, energy savings is determined by field measurement of the energy use of the systems to which an improvement measure was applied separate from the energy use of the rest of the facility. However, all of the key parameters affecting energy use are measured; there are no estimated parameters used for Option B. Measurement frequency ranges from short-term to continuous, depending on the expected variations in the savings and the length of the reporting period. Energy savings is determined through engineering calculations of the baseline and post-retrofit energy used based on the measured parameters, along with any routine adjustments.

Option C – Whole Building Metering/Utility Bill Comparisons

Option C involves the use of utility meters or whole building sub-meters to assess the energy performance of a total building. Option C assesses the impact of any type of improvement measure, but not individually if more than one is applied to an energy meter. This option determines the collective savings of all improvement measures applied to the part of the facility monitored by the energy meter. In addition, since whole building meters are used, savings reported under Option C include the impact of any other change made in facility energy use (positive or negative).

Option C may be used in cases where there is a high degree of interaction between installed improvement measures or between improvement measures and the rest of the building or the isolation and measurement of individual improvement measures is difficult or too costly.

99

2020 Energy Systems Group, LLC | Proprietary & Confidential	4/9/20 | Measurement and Verification

Teaneck Public Schools Energy Savings Plan

This Option is intended for projects where savings are expected to be large enough to be discernable from the random or unexplained energy variations that are normally found at the level of the whole facility meter. The larger the savings, or the smaller the unexplained variations in the baseline, the easier it will be to identify savings. In addition, the longer the period of savings analysis after installing the improvement measure, the less significant is the impact of short-term unexplained variations. Typically, savings should be more than 20% of the baseline energy use if they are to be separated from the noise in the baseline data.

Periodic inspections should be made of all equipment and operations in the facility after the improvement measure installation. These inspections will identify changes from baseline conditions or intended operations. Accounting for changes (other than those caused by the improvement measures) is the major challenge associated with Option C-particularly when savings are to be monitored for long periods.

Savings are calculated through analysis of whole facility utility meter or sub-meter data using techniques from simple comparison to regression analysis.

Option D – Calibrated Simulation

Option D involves the use of computer simulation software to predict energy use, most often in cases where baseline data does not exist. Such simulation models must be calibrated so that it predicts an energy use and demand pattern that reasonably matches actual utility consumption and demand data from either the base-year or a post-retrofit year.

Option D may be used to assess the performance of all improvement measures in a facility, akin to Option C. However, different from Option C, multiple runs of the simulation in Option D allow estimates of the savings attributable to each improvement measure within a multiple improvement measure project.

Option D may also be used to assess just the performance of individual systems within a facility, akin to Option A and B. In this case, the system’s energy use must be isolated from that of the rest of the facility by appropriate meters.

Savings are calculated using energy use simulation models, calibrated with hourly or monthly utility billing data and/or end-use metering.

Selecting M&V Options for a Specific Project

The tailoring of your specific M&V option is based on the level of M&V precision required to obtain the desired accuracy level in the savings determination and is dependent on:

▪ The complexity of the Energy Conservation Measure ▪ The potential for changes in performance
▪ The measured savings value.

The challenge of the M&V plan is to balance three related elements: ▪ The cost of the M&V Plan
▪ Savings certainty

▪ The benefit of the particular conservation measure.

Savings can also be non-measured. If savings are non-measured, these savings are mutually agreed upon as achieved at substantial completion of the respective facility improvement measure and shall not be measured or monitored during the term of the performance contract. Non-measured energy savings are limited to no more than 10-15% of the overall project savings.

SECTION 6. CUSTOMER SUPPORT

Maintenance Impacts/On-Going Service

New pieces of equipment that are installed as part of the ESIP project will be provided with the standard manufacturer warranty. Once installation of the equipment is complete, the remaining warranty period will be transferred to Teaneck Public School District; any warranty issues will be handled directly with the equipment manufacturer rather than with Energy Systems Group.

a) ESG subcontractors will warranty the installation for a period of 12 months, beginning at substantial completion.

b) In addition, ESG will facilitate warranty related issues for a period of 12 months, beginning at substantial completion. Extended manufacture warranties beyond the 12-month installation warranty period will be facilitated by the District.

The installation of the recommended measures will reduce the amount of emergency maintenance required bythe district through the installation of new equipment; however, preventative maintenance is still required in order to ensure the correct operation of the equipment for the expected lifetime. A service agreement cannot be included as part of this project per the New Jersey Local Finance Notice 2009-11. Once the scope is finalized and bids are received, Energy Systems Group will assist the District in preparing bids for any preventative service agreement that is felt necessary for the new equipment. The service agreement will cover recommended maintenance per each equipment manufacturer. Training on the proper maintenance and operation of each piece of equipment has also been included as part of the ESIP project which will allow the District to complete the majority of maintenance and repair in-house in order to utilize District resources.

In order to ensure the District is fully capable of achieving the energy savings and fully utilizing the new HVAC and Building Automation Systems, Energy Systems Group has included training for district employees.

Energy Systems Group recommends the District go out to bid for the following 3rd party service contracts in order to achieve the continuous savings throughout the term of the Energy Savings Improvement Program:

▪ Cogeneration Service Agreement to allow for emergency service and preventative maintenance on the new cogeneration systems. In order to receive the incentives for the cogeneration system, a 10-year maintenance contract must be in place. Energy Systems Group has shown the savings paying for this maintenance agreement but has not included the agreement within the ESIP.

Services for Lighting, Boiler Replacements, Combined Heat and Power, Plug Load Management, and walk‐ in freezer controller upgrades, such as filter changes and on-going maintenance can be completed by District staff.

Design and Compliance Issues

Teaneck Public School District will work closely with Energy Systems Group and CHA Consulting Inc. (CHA) to oversee and complete all design engineering for the purposes of public bidding of the work as well as completing construction drawings.

As part of the Energy Savings Plan development, Energy Systems Group completed a thorough analysis of the building electrical and mechanical systems including light level readings throughout the spaces. The existing light levels are typically within 10-20% of current Illumination Engineering Society (IES) recommendations, which is reasonable given the varying age of lamps throughout the District. The proposed lighting solution will continue to adhere to current IES and NJ Education Code guidelines for light levels, which in many cases may increase the current light levels to the spaces. At this time, Energy Systems Group did not observe any compliance issues in the development of this Energy Savings Plan.

Customer Risks

Asbestos reports were obtained and reviewed for all schools as part of Energy Systems Group’s safety policy. Based on the reports, asbestos materials will have to be abated prior to any work being performed. If any additional asbestos is found during the installation of the measures, Energy Systems Group will stop work and notify the School District. Any work associated with testing or remediation of asbestos containing material will be the responsibility of Teaneck Public School District. Based on the asbestos reports provided, we feel this is a low risk item.

The NJ SmartStart, NJ Clean EnergyandDemand Response EnergyEfficiencyCredit, and Combined Heat and Power Incentives outline the anticipated incentive amounts to Teaneck Public School District. Energy Systems Group does not guarantee the rebate or state incentive structure. If the programs change or the incentive amounts differ, Teaneck Public School District will be responsible to make up the difference in received incentives for the financing. The difference could result from over performance of energy conservation measures, other rebates/ incentives that may be available, restructuring the loan payment for years 1 and 2, or capital contributions by the District.

Public Engagement and Community Outreach

Student Engagement in ESIP Development: ESG has involved students at all levels in the energy related fields. AtTeaneck Public Schools, we plan to expand on interests related to energyconservation throughout the district and would welcome and actively encourage student involvement in various phases of the proposed project. Furthermore, in line with our commitment, and with Teaneck’s concurrence, we propose to offer presentations to Energy Clubs, including them in the process.

STEM EXPO Sponsorship: ESG has a history of sponsoring STEM programs for many school districts and Universities across the country. If selected, ESG would like to sponsor the Teaneck’s Annual STEM EXPO and further complement your Engineering/Technology Science curriculum.

Community Outreach Program: ESG is focused on creating a partnership with Teaneck Public School District that will extend beyond the scope of this project. Keeping the community informed and involved in the process is key to success. One way this can be achieved is thru a Community Scholarship Program. At Northern Illinois University (NIU), ESG established The Energy Systems Group Scholarship Award in Engineering to underscore our commitment. Established in 2001, ESG and NIU jointly select students for award of this scholarship. To date, we have awarded $35,000 to NIU engineering students with superior academic excellence. ESG would like to establish a similar program for Teaneck Public Schools.

ESG will seek to develop and build partnerships between The National Education Foundation (NEF) and the Teaneck Public School District. These partnerships were developed by ESG and the NEF, to bring

APPENDIX 1. ENERGY CONSERVATION MEASURES INVESTIGATED BUT NOT RECOMMENDED AT THIS TIME

ECM: Replace Exhaust Fan Motors with EC Motors ECM Summary

The District has several exhaust fans that have older low-efficiency motors and have exceeded their useful life. Although this measure results in a poor payback period, it is recommended based on the potential for energy savings, improved occupant comfort and safety concerns.

On small motor applications, Electronically Commutated (EC) Motors have the proven potential to generate significant savings. These motors are typically in sizes up to 1 horsepower, and their efficiencies are high compared to the older fractional horsepower motors. Since these motors are without mechanical brushes and the commuter reduces friction losses, they work much like Direct Current (DC) motors. They are programmable and can be used for a wide range of applications.

ECM: Destratification Fans ECM Summary

In rooms with high ceilings typically stratification of heated air occurs, resulting in air at ceiling level being warmer than the floor level. Since temperature at the floor level dictates the comfort of occupants and is typically the location of the thermostat controlling the system, this results in additional operating hours to satisfy space conditions. A de-stratification fan continuously mixes the air, balancing temperatures from ceiling to floor and wall to wall which helps the HVAC system maintain the desired temperature.

ECM: Addition of Air-Cooled Chillers ECM Summary

Some of the schools in the district have areas that are either not fully air conditioned or have systems that are in need of an upgrade/replacement. We have proposed the addition of cooling at Benjamin Franklin & Thomas Jefferson Middle Schools, in an efficient manner so that the space can be comfortably occupied throughout the year. This ECM entails the addition a high efficiencyair cooled chillingsystem. The proposed system will reduce cooling costs compared to a standard DX equipment and will include DDC controls that can be easily integrated into the proposed Building Management System.The new systems will also ensure that all equipment operates with a common, environmentally low-impact refrigerant minimizing the ozone depletion potential.

Benjamin Franklin Middle School
Concept would be to install a new 280-ton air cooled chiller setting on steel structure next to Auditorium Trane 40-ton DX Rooftop unit with HW Coil. Trane 40-ton unit would be converted; removing DX system, compressors, piping and DX cooling coil and new CHW coil installed in unit. Chiller would provide CHW from new roof mounted chiller down to boiler mechanical room connecting to new pumps with premium efficiency motors. These pumps will be piped for Dual Temperature to provide chilled water and heating hot water for each season

Thomas Jefferson Middle School
Concept would be to install a new 315-ton air cooled chiller setting on steel structure on the roof. Chiller would provide CHW from new roof mounted chiller down to boiler mechanical room connecting to new pumps with premium efficiency motors. These pumps will be piped for Dual Temperature to provide chilled water and heating hot water for each season

ECM: Replace Cafeteria Roof Top Unit at Bryant Elementary School ECM Summary

Split units in the Teaneck School District vary based on age and condition. Replacing aged split system HVAC units will reduce the operating and maintenance costs of these systems. Both heating and cooling efficiencies of split system HVAC equipment have significantly increased in the past 10 years. ESG has identified several older units that still utilize R22 refrigerant as the prime candidates for replacement.

The scope of this project would be to replace the current split HVAC system (with HW coil) that uses R22 refrigerant with a new, high-efficiency R410A split system.The new system would be adapted to the current installation for fit and functionality.

ECM: Install High Efficiency Domestic Water Heaters ECM Summary

The existing domestic water heaters at some District facilities are nearing the end of their useful life. As existing DHW boiler(s) age, they typically experience a loss in efficiency due to fouling and scaling on the internal heat exchange components, as well as an increase in maintenance costs. This measure will include replacing these units with new high-efficiency domestic water heating systems.

The existing domestic hot water heaters are standard efficiency models that operate at a nameplate value of around 80% thermal efficiency. This measure will include the installation of new hot water heaters to replace these aging, lower efficiency ones. New condensing water heaters are available that operate at efficiencies up to 97%.

ECM:Replace Water-Cooled Chiller with Air-Cooled Chiller ECM Summary

The existing (2) 100-ton water-cooled chillers at Teaneck High School are nearing the end of their useful life. As existing chillers age, they typically experience a loss in efficiency due to fouling and scaling on the internal heat exchange components, as well as an increase in maintenance costs. This measure will include replacing these units with new high-efficiency 200-ton air-cooled chiller.

The addition of the air-cooled chiller to the cooling system will allow for flexibility to add cooling more easily as the air-cooled chiller could provide cooling in the shoulder months without requiring the cooling tower to be brought online.

APPENDIX 2. ENERGY SAVINGS CALCULATIONS

Energy Savings

Energy savings were calculated using an Excel based bin calculation workbook developed by Energy Systems Group; all savings calculations and field measurements will be provided electronically.

Operational Savings New LED Fixtures
Annual operational savings are calculated based on the reduced amount of material needed for replacement of the lighting system. This is calculated by comparing the existing lifetime of the T8, HID and halogen lamps to the new lifetime of LED lighting. The calculations are based on replacements of T8 fixtures every three years, T8 ballasts every 5 years, HID lamps every 5 years and halogen lamps being replaced every 2 years. The table below highlights the various lamp types and associated replacement timing as well as total cost with replacement. These savings do not include any costs for labor to replace the bulbs or additional material needed for replacement such as lifts, replacement fixtures, new sockets, etc.

This methodology is used to determine the annual savings through the replacement of all lamp types with new LED lamps and fixtures. The fixture warranty associated with each of these replacements is 10 years. Operational savings have been claimed for a total of 5 years per the BPU regulations.

APPENDIX 4. DETAILED SCOPE DESCRIPTIONS

Design Drawings will be available electronically.

Building Envelope Weatherization Findings

AC Unit Weatherization – air conditioning units at Benjamin Franklin Elementary School are installed through-the-wall and remain in the building all year. A/C Unit Covers will eliminate unwanted air infiltration/exfiltration while the covers are in place.

Attic Flat Insulation –attic insulation is crucial for controlling conductive heat loss in a building. After air gaps are sealed and convective air loss is reduced the biggest remaining form of heat loss becomes conduction. Under-insulated surfaces at Whittier Elementary School result in excessive energy loss due to the lack of a properly insulated thermal barrier.

Caulking – there are unsealed perimeter joints and holes found at the gym window systems of Whittier Elementary School. Weaknesses at snap trim components of doors and windows at Benjamin Franklin Middle School are also allowing air to infiltrate and exfiltrate the building at small cracks in the construction of building envelope components.

Door Weather Stripping – deteriorated weather stripping materials, ineffective weather stripping installation and daylight showing at the perimeter of door systems create direct pathways for unwanted infiltration/ exfiltration throughout the school district.

Double Hung Window Weatherization – deteriorated weather stripping at double hung windows of Teaneck High School are allowing excessive air leakage at the meeting rail and bottom of lower sashes throughout the building. Double Hung window sash locks have fallen off completely at select windows and have been replaced by sliding latch locks in order to keep windows secured. The sliding latch locks do not compress the little existing weather stripping that still exists; regardless of locking hardware double hung windows are the largest building envelope weakness throughout the High School building.

Overhang Air Sealing – overhangs are roofs, floor systems or areas above entryways that extend beyond the plane of the exterior wall system. This area of construction at the Bryant Elementary School was misunderstood by builders and the cavity that extends beyond the plane of the exterior wall system was incorrectly “connected” to the interior heated spaces of the building in many locations. Overhangs that are not properly sealed at the plane of the surface that should separate the conditioned space from the outdoors lead to excessive air leakage and heat loss at these vulnerable areas in the building envelope.

Overhead Door Weather Stripping/ Roll-up Door Weather Stripping – remove existing weather stripping and replace with new commercial grade weather stripping to create a full air seal around the door. With low grade, none, or deteriorating materials in place overhead and roll-up doors are a major air leakage sources.

Roof-Wall Intersection Air Sealing – the roof-wall intersection is regularly an area that allows unwanted air leakage through the building shell. Exterior flashing and finish details at this area are not constructed to stop air leakage (exterior flashings are for water control, not air control); unsealed exterior flashing details combine with interior gaps in the framing between the roof and wall assemblyto allow infiltration/ exfiltration.

Teaneck Public Schools Energy Savings Plan

Window Weatherization –glazing gaskets throughout the High School building were installed poorlyor have deteriorated badly resulting in small air gaps at the intersection between muntions, mullions and glass components.

Building Envelope Improvement Recommendations

•	AC Unit Weatherization

o A/C Unit Covers (Benjamin Franklin MS) – install rigid coverings over all relevant A/C units as noted on floor plan.
•	Attic Flat Insulation

o 10” Open Blow Cellulose (Whittier ES) – install 10 inches of cellulose across the attic flat. •	Caulking
•	Door Weather Stripping

•	Double Hung Window Weatherization

o Double Hung Window Weatherization (Teaneck High School) – where the meeting rail lock has been removed; install continuous mechanically fastened Q-lon weather stripping to bottom sash so as to compress against the gap between the upper and lower sash at the meeting rail. Where the meeting rail sash lock is in place; separate the upper and lower sash for the purpose of cleaning the upper sash “U-channel” receiving weather barrier. Vacuum out debris and metal brush channel to receive sealant. Apply siliconized acrylic sealant to channel. Close and lock window inserting PVDC monofilaments to keep the sealant in the “U-channel” from adhering to the upper sash. Remove the monofilaments once the sealant is cured. Install PVC foam Weatherseal Tape to sill so as to receive lower sash at the interior frame. Make upper sash stationary and caulk in place to eliminate air leakage at upper sash.

•	Overhang Air Sealing

•	Overhead Door Weather Stripping/ Roll-up Door Weather Stripping

•	 Weather Strip (Teaneck High School) – install heavy-duty aluminum carrier with oversized vinyl insert gasket at the sides: install heavy-duty aluminum carrier with an oversized bottom U-style gasket at bottom.
•	Roof-Wall Intersection Air Sealing •	Window Weatherization
•	 Custom WindowWeatherization (Teaneck High School) – install Sascho Big Stretch caulk at failed and missing glazing bead corners of all windows. Caulk is to be applied at corners and full lengths of windows where existing glazing gaskets are missing or damaged.
