ABSTRACT

The purpose of the study was to investigate and report on methods of energy conservation at the

town of Bethel – White Lake, NY. The town of Bethel was incorporated in 1809 from the town of

Lumberland by an act of the New York State Legislature. Hamlets that the town serves are Bethel,

Kauneonga Lake, Smallwood, White Lake, parts of Mongaup Valley and Swan Lake covering 93.51

square miles. There are over 147 miles of Town Roads. The population according to the 2010 Census

is 4,205. In 1969, Bethel hosted the original Woodstock Music and Art Festival that is now the site of

Bethel Woods Performing Arts Center and the Bethel Woods Museum.

Data was gathered by an experienced team of energy engineers during on-site surveys through the

visual observation of the buildings and their energy consuming systems, analysis of energy records

pertaining to electricity, fuel oil and propane and interviews with operating personnel.

EXECUTIVE SUMMARY

S.1 DESCRIPTION OF STUDY

This Energy Audit Report Study consisted of identifying, analyzing and recommending energy

conservation measures (ECMs) to help reduce energy costs and consumption at the Bethel Town

Hall, Bethel Highway Garage and Kauneonga Lake Sewer Treatment Plant - White Lake, NY. This

report also fulfills the deliverable for the NYSERDA Renewable Heat New York Biomass Boiler

Program.

The energy survey of the Bethel Town Hall, Bethel Highway Garage and Kauneonga Lake Sewer

Treatment Plant, here by referred to as Town Hall, Highway Garage and Sewer Treatment Plant, was

conducted by L&S Energy Services, Inc. on September 18th, 2014. The properties were previously

audited as part of the NYSERDA Small Commercial Audit Program in 2009. The audit was

conducted on a sunny day with temperatures near 70°F. The purpose of the survey was to evaluate

building energy usage, study and recommend energy conservation measures (ECM’s) for specific

equipment in each building. Lighting, mechanical, process and architectural systems were surveyed

for potential energy conservation opportunities. Energy bills and documentation were provided by

the site contact and reviewed. Walk-through audits were performed to observe existing systems and

operations including: obtaining equipment nameplate data, reviewing operational schedules, and

procuring annual electric and fossil fuel utility bills and consumption schedules. Trend data was not

collected, as run hours were provided by the facility manager for the equipment in each building.

The results of these activities shall be used to recommend energy efficiency improvements.

For the one year period from September 2013 through August 2014, the Town Hall used a total of

21,402 kWh at a cost of $3,142. The Highway Garage used a total of 64,959 kWh at a cost of $6,083

and the Sewer Treatment Plant used a total of 606,600 kWh at a cost of $63,559. Electricity is supplied

by Integrys and delivered by NYSEG for the three accounts on a NED0200E00 – Nonresidential rate.

Although in recent history, electricity was supplied by Hess for all three sites.

Propane and fuel oil information was provided showing sporadic deliveries during the 2013 year.

This fuel is supplied for heating and hot water. The Town Hall is estimated to have used a total of

870 gallons of oil #2 at a cost of $2,944. The Highway Garage used a total of 4,580 gallons of propane

at a cost of $8,157 and the Sewer Treatment Plant used a total of 2,178 of oil #1 at a cost of $6,599.

Single deliveries of oil #2 to the Highway Garage and Sewer Treatment Plant were also reported and

appear to be for portable heating equipment. This fuel use is ignored for the purpose of this analysis



due to the fact that it’s not serving permanent equipment. Propane is supplied and delivered by

Mirabito and fuel oil by Ultra Power.

The total annual energy cost for the sites is $90,484 or $1.60 per sq-ft for the Town Hall and $3.56 per

sq-ft for the Highway Garage. The Sewer Treatment Plant garage/office is unoccupied, as discussed

later in the report. A utility bill summary is included in Appendix A.

It is useful to compare the relative cost of energy among the various fuels. The cost per million Btus

($/MMBtu) was calculated for the energy sources available to the town of Bethel.

Utility Type Area Unit Cost $/MMBtu

Electricity Town Hall $0.15/kWh $43.02/MMbtu

Highway Garage $0.09/kWh $27.45/MMbtu

Sewer Treatment Plant $0.10/kWh $30.71/MMbtu

Fuel Oil #2 Town Hall $3.38/Gal $24.24/MMbtu

Propane Highway Garage $1.78/Gal $19.50/MMbtu

Fuel Oil #1 Sewer Treatment Plant $3.03/Gal $22.06/MMbtu

Notes:

1. Wood pellets are analyzed with a rate of $250/ton. This amount can vary widely depending

on the delivery method available in the area. For example, the rate may be lower if a bulk

vacuum delivery is available versus bag delivery. The distance of the delivery will also

impact price.

2. The average propane rate calculated from the 2013 deliveries for the Highway Garage is

significantly lower than 2014 average rate of $3.21.gal for Middle Hudson Region. The trend

shows a significant increase in propane prices throughout 2014, only to tail off towards the

end of the year. Therefore, a rate of $2.89/Gal is used in the analysis for this building, as it is

the most recent rate listed for this region.

For each qualified measure a cost estimate was prepared. The costs for the ECMs were developed by

using industry standard cost estimating tools (‘Means 2012') and/or by contacting local

representatives from various building system manufacturers and installers. The estimated costs for

all ECMs are included in Appendix C. Energy use and projected cost savings were calculated using

spreadsheet analysis. ECM analysis and calculation data are included in Appendix B. The simple

payback period for each measure was calculated. A description was prepared for each measure, and

those measures that are cost effective were incorporated in the energy study.

A summary of the recommended energy efficiency measures is shown in Figure 1 below.

Based upon full implementation of all recommended ECMs, the annual savings currently projected in

this analysis are $9,342 per year. The present combined annual energy cost of $90,484, as

summarized above, would be reduced to $81,142 and represents approximately a 10.3 percent

savings in the yearly energy costs. The estimated capital cost of implementing all recommended

measures is $143,800 with a simple payback period of 15.4 years.

The ECM savings were estimated utilizing spreadsheet calculations and have been adjusted based on



site observations and discussions with the town of Bethel staff. This report represents the final

deliverable and savings assumptions are based on the conditions present at the site at the time of the

initial audit.

Additionally, the New York State Energy Research and Development Authority (NYSERDA),

through the New York State Energy $mart Program, is offering financial support to qualified

customers who implement energy efficiency measures through a wide variety of programs. Some of

the proposed conservation measures may be eligible for NYSERDA incentives, which will reduce the

installed cost. Measures that save electricity or fossil fuel may be eligible for the support through

participation in the NYSERDA Existing Facilities Program or Renewable Heat New York Biomass

Boiler Program.

EXISTING CONDITIONS

1.0 BUILDING OVERVIEW

There are 3 buildings in the Town of Bethel that are the focus of this study; the Town Hall, Highway

Garage and Sewer Treatment Plant.

The Town Hall is 3,800 square feet with only one story, built in the 1960’s. The building contains

offices, a kitchen, bathrooms and a semi-conditioned basement.

The Highway Garage is 4,000 square feet also with one story, built in the 1960’s. The building is

utilized as the main operations center for highway truck repair, storage and office operations.

The Sewer Treatment Plant project focuses on the Fischer Porter Ultraviolet Disinfection System,

which is approximately 15 years old. The building that was primarily occupied recently burned in a

fire and is in the schematic phases of renovation. The staff is currently utilizing a temporary trailer.

The buildings follow an 8am – 5pm schedule year round, with the Highway Garage working

extended hours during extreme weather events.

1.1 Architectural

The Town Hall is constructed of masonry block with an exterior brick

façade. The roof is covered by a red metal roof with the old asphalt

shingles underneath. The roof contains R-30 batt insulation and the

wall insulation is R-11 batt insulation. The windows are thermo-pane

with a mix of fixed and operable double pane.

The Highway Garage is also constructed of masonry block without

wall insulation. The roof is covered with asphalt shingles. The floor of

the attic in the building contains R-19 batt insulation. The few

windows that exist are fixed single glaze with a newer single glaze

window installed within the inside frame. Five motorized overhead

metal insulated doors are located at the front of the building.

1.2 Mechanical

The Town Hall is heated by an oil fired forced air furnace, with no supplied ventilation. Occupants

open windows or doors to allow in fresh air. The unit also provided mechanical Dx cooling, but was



abandoned after the compressor and condensing unit failed. The occupants now utilize window and

portal air conditioners, which are likely undersized to handle peak cooling loads. The options

analyzed in this report do include the addition of mechanical ventilation.

The furnace utilizes programmable thermostats, but was in manual mode

and had not been programed at the time of the audit, although the staff

indicated programming had been used in the past. L&S Energy Services

programmed the thermostats to the occupant’s preferred hours and

temperatures for the occupied and unoccupied periods. The portal air

conditioners utilized manual controls. Portable space heaters are also

used for supplemental heat, as comfort requirements vary amongst the occupants.

The Highway Garage is heated by two propane fired unit heaters with manual control. There is no

mechanical cooling. The office utilizes a seven foot strip electric heater with manual control that runs

the entire winter. Although not analyzed here, this operation could be reduced or limited altogether

by insulating the office from the garage.

The town is investigating biomass boiler systems as part of the Renewable Heat NY Biomass Boiler

Program for the Town Hall and Highway Garage.

8 with switch control and wall mounted occupancy sensors in the bathroom. The exterior lights are

incandescent at the entrances and building perimeter. The exterior lighting is also controlled by a

switch.

The lighting in the Highway Garage is metal halide through the majority of the garage, T-12 in the

workshop and the remaining incandescent, all controlled by switches. The exterior lights are

incandescent and on a timer.

1.4 Process and Plug Loads

The Town Hall plug loads include computers, kitchen equipment, printers, vending machine and as

previously noted, portal heaters.

The Highway Garage contains 2 air compressors, detailed in Figure 3 below, various shop tools and

block heaters. An exhaust fan also exists in the attic and is used sparingly, so not looked at for this

study. There is significant spike in electricity use during the winter, as detailed in Appendix A,

which is primarily contributed to block heaters on the trucks.

Figure 3: Process

The existing Ultraviolet disinfection system, at the Sewer Treatment

Plant, is 15 years old and contains a quantity of 60 lamp assemblies at 67

watts each. 3 control cabinets enclose 5 banks, which control 4 lamp

assemblies each. Only 1 control cabinet is typically energized with the

second activated for overflow. The Ultraviolet disinfection system

operates from May 15th though October 15th, to assist with treating the extra waste associated with the

increased occupancy during the summer. The system is shut off during the winter months.

1.5 Domestic Hot Water

Domestic hot water is supplied in the Town Hall and Highway Garage by electric domestic hot water

heaters with storage tanks.

Detailed performance characteristics for the hot water system are included in Figure 4.

EXISTING CONDITIONS:

The Town Hall is conditioned with an inefficient oil fired force air furnace that is at the end of its

useful life. The performance characteristics are included in Figure 2 on page 1-2.

ECM SPECIFICATIONS:

Remove the existing furnace and install an oil fired condensing furnace.

The condensing oil fired furnace was analyzed with the same nameplate capacity as the existing

furnace, but with an efficiency of 93.5%, based on manufacturing specifications.

ACTION ITEMS:

This ECM is recommended for further study, in the occasion that neither the VRV or biomass options

are installed. Oil fired condensing units at this capacity are not readily available and the

manufacturer reference for this analysis is no longer selling the unit due to malfunction issues. This

would be the most cost effective option, if the unit was available and reliable.

The Town Hall utilized an inefficient condensing unit with compressor for split central air

conditioning. The evaporator section of the split system is located above the furnace. The unit

recently failed and in the interim, the town utilizes portal and window air conditioners until a

permanent solution is found for central air conditioning. The performance characteristics of the unit

are included in Figure 2 on page 1-2.

ECM SPECIFICATIONS:

Replace the existing condensing unit with a high efficiency unit. The indoor evaporator is assumed

to be adequate.

The condensing unit was analyzed with the same nameplate capacity as the existing unit, but with a

full load efficiency of 11.5 EER, based on manufacturing specifications.

ACTION ITEMS:

This ECM is not recommended in lieu of TH-ECM-1 (Option 5)

The Town Hall is conditioned with an inefficient oil fired force air furnace and an inefficient

condensing unit with compressor for split central air conditioning. The performance characteristics


ECM SPECIFICATIONS:

Install a high efficiency variable refrigerant volume (VRV) air source heat pump system and biomass

hot water boiler system sized to handle 100% of the peak heating loads in the building. The systems

would replace the central cooling split system and the oil fired heat exchanger in the existing furnace.

The VRV was modeled utilizing manufacturer performance information and is assumed to utilize 4

indoor evaporator units, each thermostatically controlled. The system is sized for the peak cooling

load with a capacity of 5 tons and has a full load cooling efficiency of 12.2 EER and heating COP of

3.1. The load on the system varies as the sun travels over the building, which results in changes in

compressor speed and mechanical cooling savings. The system will be primarily used for cooling in

the summer; however it is capable of handling heating loads during the shoulder seasons up to 5.5

tons, or approximately 38% of the peak heating load. The system is not capable of simultaneously

heating and cooling. As part of the design process, ensure that the VAV system is large enough to

prevent freezing in the building in the event that the biomass boiler is shut down. This design may

also require the approval from the insurance company for the building. The VAV system operates

close to capacity down to outside air temperatures of 5°F. The variable speed compressor

performance curves were obtained from an eQUEST simulation, as they were not made available by

the manufacturer.

The biomass boiler was analyzed with a system capable of handling 100% of the peak heating loads

in the building. According to the manufacturer, the full load efficiency of the 47.8 kW (163 MBH)

Town of Bethel



system is 96.2%. The boiler is fired with low moisture pellets and is controlled by temperature

sensors located in the hot water buffer tank. The existing furnace housing, fan and ductwork would

remain, while the oil fired burner and heat exchanger would be replaced with a hot water coil fed

from the buffer tank. The calculation utilizes manufacturer performance curves and also allows for

additional hot water pump power that will be required. During warmer winter days, the boiler runs

less, as the charged buffer tank satisfies the building loads determined by the thermostat set-point.

ACTION ITEMS:

This ECM is not recommended in lieu of TH-ECM-1 (Option 5). Industry professionals generally do

not advise that a biomass boiler system be sized to handle 100% of the heating load, as the boiler

cycles more often and the buffer tank is utilized less often during peak periods. This is observed in

the calculation of full load hours for the full load option of 528 EFLH’s compared to 876 EFLH’s for

the part load option. Additionally, the NYSERDA Renewable Heat New York Biomass Boiler

Program does not incentive biomass boiler systems sized for 100% of the heat load.

ECM SPECIFICATIONS:

Install a high efficiency variable refrigerant volume (VRV) air source heat pump system and biomass

hot water boiler system sized to handle less than 60% of the peak heating loads in the building. The

systems would replace the central cooling split system and the oil fired heat exchanger in the existing

furnace.


indoor evaporator units, each thermostatically controlled. The system is sized for the peak heating

load with a capacity of 6.7 tons and has a full load cooling efficiency of 13 EER and heating COP of


compressor speed and mechanical cooling savings. The system will be used for cooling in the

summer, simultaneous heating and cooling during the shoulder seasons and auxiliary heating

required when loads exceed the biomass boiler system capacity.

As part of the design process, ensure that the VAV system is large enough to prevent freezing in the

building in the event that the biomass boiler is shut down. This design may also require the approval

from the insurance company for the building. The VAV system operates close to capacity down to

outside air temperatures of -7.5°F. The variable speed compressor performance curves were obtained

from an eQUEST simulation, as they were not made available by the manufacturer.

The biomass boiler was analyzed with a system capable of handling 55% of the peak heating loads in

the building. According to the manufacturer, the full load efficiency of the 27.6 kW (94 MBH) system

is 90.8%. The boiler is fired with low moisture pellets and is controlled by temperature sensors

located in the hot water buffer tank. The existing furnace housing, fan and ductwork would remain,

while the oil fired burner and heat exchanger would be replaced with a hot water coil fed from the

buffer tank. The calculation utilizes manufacturer performance curves and also allows for additional

hot water pump power that will be required. During warmer winter days, the boiler runs less, as the

charged buffer tank satisfies the building loads determined by the thermostat set-point.

This option provides the best year round comfort for the occupants.

ACTION ITEMS:

This ECM is not recommended in lieu of TH-ECM-1 (Option 5). This option may warrant further

consideration if year round occupant comfort is of concern or if support through NYSERDA’s

Renewable Heat New York Biomass Boiler or Existing Facilities Programs offsets the implementation

cost enough to achieve a reasonable payback.

TH-ECM-1 (Option 5) Evaluate High Efficiency Heat Pumps (VRV) PROJECT COST: $71,800 SIMPLE PAYBACK: 28.8 Years ELECTRICAL ENERGY SAVINGS: -3,376 kWh/Year DEMAND SAVINGS: -1.9 kW/Month NET FUEL SAVINGS: 122.3 MMBtu/Year ANNUAL ENERGY COST SAVINGS: $2,496





ECM SPECIFICATIONS:

Replace the existing central cooling split system and the oil fired furnace with a high efficiency

variable refrigerant volume (VRV) air source heat pump system.


indoor evaporator units, each thermostatically controlled. The system is sized for the peak heating

load with a capacity of 13.3 tons and has a full load cooling efficiency of 13 EER and heating COP of


compressor speed and mechanical cooling savings. The system will be used for cooling in the

summer, simultaneous heating and cooling during the shoulder seasons and heating during the

winter. The variable speed compressor performance curves were obtained from an eQUEST

simulation, as they were not made available by the manufacturer.

ACTION ITEMS:

This Town of Bethel has expressed interest in pursuing this option and is therefore recommended.

The reasons for pursuing this option include; single fuel source in electricity that can eventually be

tied into a photovoltaic system, elimination of fossil fuels, low operation and maintenance costs as

compared to a biomass system. In addition, VRV systems offer decentralized heating and cooling, so

individual temperature requirements can be met. When coupled with the optional branch circuit

controller, VRV systems are capable of providing simultaneous mechanical cooling and free heating.

TH-ECM-1 (Option 6) ECM DESCRIPTION: Evaluate Part Load Biomass Boiler w. Condensing Boiler PROJECT COST: $33,600 SIMPLE PAYBACK: 27.0 Years ELECTRICAL ENERGY SAVINGS: -678 kWh/Year DEMAND SAVINGS: -0.1 kW/Month NET FUEL SAVINGS: 21.6 MMBtu/Year ANNUAL ENERGY COST SAVINGS: $1,246


The Town Hall is conditioned with an inefficient oil fired force air furnace. The performance

characteristics are included in Figure 2 on page 1-2.

ECM SPECIFICATIONS:

Install a biomass hot water boiler system sized to handle less than 60% of the peak heating loads in

the building and a condensing oil fired boiler for auxiliary heat. The systems would replace the oil

fired heat exchanger in the existing furnace.

The biomass boiler was analyzed with a system capable of handling 55% of the peak heating loads in

the building. According to the manufacturer, the full load efficiency of the 27.6 kW (94 MBH) system

is 90.8%. The boiler is fired with low moisture pellets and is controlled by temperature sensors

located in the hot water buffer tank. The existing furnace housing, fan and ductwork would remain,

while the oil fired burner and heat exchanger would be replaced with a hot water coil fed from the

buffer tank. The calculation also allows for additional hot water pump power that will be required.

During warmer winter days, the boiler runs less, as the charged buffer tank satisfies the building

loads determined by the thermostat set-point.

The condensing boiler was modeled with a full load capacity of 95 MBH and an efficiency of 91.5%,

based on manufacturer specifications. The condensing boiler supplements the biomass boiler with

hot water, when loads exceed the biomass boiler system capacity. As part of the design process,

ensure that the auxiliary boiler is large enough to prevent freezing in the building in the event that

the biomass boiler is shut down. This design may also require the approval from the insurance

company for the building.

Town of Bethel



ACTION ITEMS:

This ECM has the best payback of the all the options, however the Town of Bethel has opted not to

pursue this option in favor of TH-ECM-1 (Option 5). The payback may be further reduced through

support from NYSERDA’s Renewable Heat New York Biomass Boiler Program.

TH-ECM-2 ECM DESCRIPTION: Evaluate Exterior Lighting Fixtures with LED PROJECT COST: $2,100 SIMPLE PAYBACK: 14.0 Years ELECTRICAL ENERGY SAVINGS: 1,668 kWh/Year DEMAND SAVINGS: 0 kW/Month NET FUEL SAVINGS: 0 MMBtu/Year ANNUAL ENERGY COST SAVINGS: $150


There are 5 outdoor fixtures using incandescent bulbs. All are controlled by a timer or switch. The

fixtures are listed on the calculation sheets of Appendix B.

ECM SPECIFICATIONS:

Replace these fixtures with high-efficiency LED lighting. This measure saves energy because the LED

lighting operates at nearly a third of the power of the present fixtures.

ACTION ITEMS:

This ECM is recommended. Engage a vendor with lighting design experience to survey, measure,

and verify appropriate lighting level requirements. Get quotes for installation of the recommended

lighting measure.

HG-ECM-1 ECM DESCRIPTION: Evaluate Air Compressor with Rotary Vane Type PROJECT COST: $9,600 SIMPLE PAYBACK: 41.7 Years ELECTRICAL ENERGY SAVINGS: 2,552 kWh/Year DEMAND SAVINGS: 0 kW/Month NET FUEL SAVINGS: 0 MMBtu/Year ANNUAL ENERGY COST SAVINGS: $230


The air compressors provide the working force for the truck maintenance tools in the highway

garage. The primary air compressor is constant speed and operates up to 175 psi. The secondary air

compressor is older and primarily supplements the newer air compressor when the operating

pressure cannot be met. There are more efficient technologies available that avoid wasted energy

caused by excessive pressure band or unloaded running.

The performance characteristics are included in Figure 3 on page 1-3.

ECM SPECIFICATIONS:

Replace the existing air compressors with a 10 HP variable speed high-efficiency rotary vane air

compressor with an operating range of 200 psi. This measure saves energy by reducing the speed of

the compressor motor as the operating pressure decreases rather than running full speed

unnecessarily, and therefore saving electricity exponentially.

If an outside air option exists for the new air compressor, install an air intake pipe to draw outside

air. The option saves energy because cool air is denser than warm air, and a compressor works less to

compress a specific volume of air if the air is cooler. Since the average outdoor air temperature in the

winter is below that of the heated garage, the compressor will work more efficiently if it draws

outdoor air.

ACTION ITEMS:

This ECM is not recommended based on its long payback.

HG-ECM-2 ECM DESCRIPTION: Evaluate Interior Fixtures with High Efficiency Fluorescent PROJECT COST: $6,200 SIMPLE PAYBACK: 10.2 Years ELECTRICAL ENERGY SAVINGS: 14,170 kWh/Year DEMAND SAVINGS: 3.6 kW/Month NET FUEL SAVINGS: -21.1 MMBtu/Year ANNUAL ENERGY COST SAVINGS: $607


The interior fixtures consist of T-12 bulbs on 41 or 113.5 watt ballasts and 460 watt HID’s. They

operate 7 days a week and during working hours. The fixtures are listed on the calculation sheets

located in Appendix B.

ECM SPECIFICATIONS:

Replace T-12 fixtures and HID with high performance T-8. A total of 25 fixtures should be upgraded.

This measure saves energy by increasing the efficacy of the lighting system. Therefore, standard light

levels are maintained with fewer watts consumed when the lights are in operation. Heat gain and the

subsequent cooling load, are also reduced, reducing summertime demand.

HG-ECM-4 ECM DESCRIPTION: Evaluate Part Load Biomass Boiler PROJECT COST: $65,500 SIMPLE PAYBACK: 9.2 Years ELECTRICAL ENERGY SAVINGS: -1,626 kWh/Year DEMAND SAVINGS: -0.5 kW/Month NET FUEL SAVINGS: 65.4 MMBtu/Year ANNUAL ENERGY COST SAVINGS: $7,128


The Highway Garage is conditioned with inefficient propane fired ceiling mount unit heaters. The

performance characteristics are included in Figure 2 on page 1-2.

ECM SPECIFICATIONS:

Install two biomass hot water boiler systems sized to handle less than 60% of the peak heating loads

in the building. The existing unit heaters would remain in place for auxiliary heat.

Biomass boilers were analyzed with systems capable of handling 53% of the peak heating loads in the

building. According to the manufacturer, the full load efficiency of the 47.8 kW (163 MBH) system is

96.2% and the full load efficiency of the 27.6 kW (94 MBH) system is 90.8%. The boilers are fired with

low moisture pellets and are controlled by temperature sensors located in the hot water buffer tank.

Dedicated unit heaters with hot water coils fed from the buffer tank would also be installed. The

calculation allows for additional fan and hot water pump power that will be required. During

warmer winter days, the boiler runs less, as the charged buffer tank satisfies the building loads

determined by the thermostat set-point.

The existing propane fired unit heaters supplement the biomass boilers, when loads exceed the

biomass boiler system capacity. The unit heaters also act as a back-up source of heat, in the event that

the biomass boiler shuts down. The electric strip heater is not considered here, as it is in a separate

zone from the unit heaters and could be eliminated with proper insulation in the office.

ACTION ITEMS:

This ECM is recommended. The payback may be further reduced through support from NYSERDA’s

Renewable Heat New York Biomass Boiler Program.

Refer to Appendix D for manufacturer performance data.

STP-ECM-1 ECM DESCRIPTION: Evaluate Fischer Porter Ultraviolet Disinfection System PROJECT COST: $35,000 SIMPLE PAYBACK: 315.2 Years ELECTRICAL ENERGY SAVINGS: 1,110 kWh/Year DEMAND SAVINGS: 0.5 kW/Month NET FUEL SAVINGS: 0 MMBtu/Year ANNUAL ENERGY COST SAVINGS: $111


The existing ultraviolet disinfection system utilizes 67 W magnetic ballasts with an UV intensity of

95.3 uW/cm2.

ECM SPECIFICATIONS:

Replace the cabinets containing the magnetic ballasts with electronic ballast cabinets. The lamp racks

could be re-used. While the lamp wattage increases from 67 W to 70 watts, the UV intensity also

increases from 95.3 to 121.5 uW/cm2. The analysis assumes that the high rate UV intensity would

allow for fewer lamps required to achieve the same level of disinfection.

Trending for electrical use was not completed because the staff stated that the lamps are on for all

hours from May 15th though October 15th. The power consumption was obtained from the

manufacturer and confirmed through a spot power reading.

ACTION ITEMS:

This ECM is recommended based on end of life replacement in the event parts become difficult to

find.

TH-ECM-1 (Option 3): Evaluate Full Load Biomass Boiler w. VRV

The existing oil fired heat exchanger in the furnace is replaced with a biomass boiler supplied hot water heat exchanger, sized to satisfy the peak heating loads in the building.

Sequence of Operations: The biomass boiler is enabled when the outside temperature falls below40°F, to initially charge the hot water buffer tank to satisfy its setpoint temperatures. The buffertank is sized to satisfy the building heating loads at higher outside air temperatures and minimizeboiler cycling. As the outside air temperature decreases and building heating loads increase, thebiomass boiler will fire for longer periods of time in an attempt to recharge the buffer tank. Thebuilding programmable thermostat controls the furnace fan.

1. Sample water circulation (KG/HR) provided by EVOWORLD. Actually flow to be determined during design.2. GPM = KG/HR / (277 * 1 SG of H2O)3. Watts = GPM * 19 W/GPM (ASHRAE 90.1-2010 G3.1.3.5)

TH-ECM-1 (Option 4): Evaluate Part Load Biomass Boiler w. VRV

The existing oil fired heat exchanger in the furnace is replaced with a biomass boiler supplied hot water heat exchanger, sized to satisfy 55% of the peak heating loads in the building.

Sequence of Operations: The biomass boiler is enabled when the outside temperature falls below40°F, to initially charge the hot water buffer tank to satisfy its setpoint temperatures. The buffertank is sized to satisfy the building heating loads at higher outside air temperatures and minimizeboiler cycling. As the outside air temperature decreases and building heating loads increase, thebiomass boiler will fire for longer periods of time in an attempt to recharge the buffer tank. Thebuilding programmable thermostat controls the furnace fan.

TH-ECM-1 (Option 6): Evaluate Part Load Biomass Boiler w. Condensing Boiler

Sequence of Operations: The biomass boiler is enabled when the outside temperature falls below55°F, the hot water buffer tank is initiallycharged to satisfy its setpoint temperatures. The buffer tankis sized to satisfy the building heating loads at higher outside air temperatures and minimize boilercycling. As the outside air temperature decreases and building heating loads increase, the biomassboiler will fire for longer periods of time in an attempt to recharge the buffer tank. The auxiliaryboilerfires when the load exceeds the biomass boiler capacity. The building programmable thermostatcontrols the furnace fan.

The existing oil fired heat exchanger in the furnace is replaced with a biomass boiler supplied hotwater heat exchanger, sized to satisfy 55% of the peak heating loads in the building. An in-linecondensing oil fired boiler acts as an auxiliary to the biomass boiler.

HG-ECM-4: Evaluate 60% Biomass Boiler

A biomass boiler and propeller hot water unit heater are installed, sized to satisfy 55% of the peak heating loads in the building. The existing unit heaters act as auxiliary to the biomass boiler.

Sequence of Operations: The biomass boiler is enabled when the outside temperature falls below55°F, to initially charge the hot water buffer tank and satisfy its setpoint temperatures. The buffertank is sized to satisfy the building heating loads at higher outside air temperatures and minimizeboiler cycling. As the outside air temperature decreases and building heating loads increase, thebiomass boiler will fire for longer periods of time in an attempt to recharge the buffer tank. Theauxiliary heaters fire when the load exceeds the biomass boiler capacity. The buildingprogrammable thermostat controls the heater fan and the hot water pump.

3.2 Function check / safety temperature limiter on the boiler The functional check of the temperature controller and the safety temperature limiter and monitor on the boiler was performed in accordance with section 5.13 of ÖNORM EN 303-5. The require-ments were fulfilled.

3.3 Function check to verify the rapid shutdown of the system

Since the tested pellet burner EVOTHERM P 50 from the company Evotherm Heiztechnik Ver-triebs GmbH is not equipped with a device to dissipate the residual heat as described in section 4.1.5.11.3 of ÖNORM EN 303-5:1999, the operating and fault conditions associated with a power outage and sudden loss of heat extraction were simulated in order to satisfy the definition of a burner system with a rapid shutdown facility. During the course of the checks on the temperature controller, the safety temperature limiter and the rapid shutdown facility no dangerous operating conditions arose neither with the water system nor the burner.

Appendix E – NYSERDA Incentives

The following table and subsequent worksheets provide an estimate of incentives that may be available through NYSERDA,

if the Town of Bethel were apply today with the HVAC equipment analyzed in this report. The availability and amount of

incentives may change per the discretion of NYSERDA. The RHNY incentive is impacted by the cost of the biomass system

and therefore may change once final costs are determined. The lighting incentive is an example based on the types of fixtures

that were analyzed in this study. The incentive amounts will most likely change based on the final lighting design. L&S can

assist with finalizing the incentive documents and handling correspondence with NYSERDA.
