3 Introduction The Lakeville Town Hall is a two-story facility attached to the Fire Station. Total square footage of the facility is approximately 6,3 and built in 898. An Energy Audit was performed at this facility and reviewed the following: Lighting and lighting controls Hot water heating system Domestic hot water heating system HVAC controls Plug load controls Building envelope improvements During this process TNT Energy identified several Energy Conservation Measures (ECM s), which have the potential for both electric and gas savings. Energy Conservation Opportunities ECM#: Lighting efficiency upgrades The existing lighting throughout the facility consists of mostly T8 fluorescent technology, while this technology is fairly efficient, new LED lighting provides an opportunity to reduce the wattage even further while maintaining light levels and improving light quality. There are several opportunities to upgrade the existing lighting and lighting controls throughout the facility to LED lighting technologies. There are also areas that would save energy if Occupancy and Vacancy sensors were installed to better control the use of lighting. Office ceiling lights Hallway ceiling lights Outdoor lighting Phone: Fax: Unit A Web: Town Hall Page Raynham, MA

4 Recommendations:. Replace or upgrade existing lighting fixtures with new high efficiency LED fixtures or LED retrofit kits.. See Schedule A for itemized list. LED ceiling lights LED hallway lights LED outdoor lights ECM#: Lighting controls Lighting controls provide opportunities for energy savings in areas that are not occupied 00% during business hours. Wired and wireless sensors can be utilized to monitor spaces and turn off lights when occupants leave the area for extended periods of time. In small spaces such as closets and individual bathrooms, wired occupancy switches can be installed to replace the existing light switch. In larger office spaces, wireless technology can be utilized to keep lights on when only a few people are in the space. Recommendations:. Install occupancy sensors in areas that are not always used to automatically turn on lights when the occupant enters the space and will automatically turn off.. Install vacancy sensors in rooms and closets that are not frequently used so that the occupant will need to push the button to turn the light on and will automatically turn off.

5 Wall switch Wireless ceiling sensor Wireless wall switch ECM#3: Hot Water Heating System The existing hot water heating system consists of () oil fired hot water boiler rated at MBH currently firing at a rate of 9 MBH. There is an outdoor air combustion air duct that does not have a motorized control damper interlocked with the boiler. There are 6 zones of heat, each served by an individual thermostat, circulator, and zone control relay. There are no outdoor air reset controls; currently the boiler temperature is set at 80F year round. Hot water boiler Combustion air duct Zone circulators Recommendations:. Replace the existing boiler with a new high efficiency oil fired boiler. The existing boiler efficiency is approximately 75% taking into consideration combustion and boiler efficiencies. A new 3-pass boiler has an 86.8% AFUE Efficiency. Phone: Fax: Unit A Web: Town Hall Page Raynham, MA

6 . Replace the six existing zone circulators with new high efficiency Delta-T circulators. New pumps have high efficiency motors that use less energy when running. They also monitor supply and return temperatures and modulate speed in order to maintain a differential temperature of 0F to maximize boiler efficiency. 3. Install an outdoor air sensor to enable and disable the heating circulating pumps based on outdoor air temperature. Many times the occupants of the building turn up the heat even when there is no demand for heating. Shutting off the building heat automatically when the outdoor temperature rises above set point will save energy.. Install an outdoor air reset controller on the new boiler. During the shoulder seasons, 80F boiler water is not required to adequately heat the building. By lowering the boiler temperature according to the outdoor air temperature, the boiler will consume less energy. 5. Install a motorized draft control damper. Draft control damper installed on the flue between the boiler and the chimney will reduce standby losses from the boiler and prevent hot air from the boiler going up the chimney. 6. Install a new combustion air louver, duct and damper. Interlock with the boiler control to open when the boiler fires. Currently the existing combustion air duct has no damper installed on it, which allows cold air to enter the boiler room year round, this wastes energy and also provides an opportunity for freezing pipes in the winter. There are also pipes that pass through the existing louver which need to be relocated. New hot water boiler Draft control damper New zone circulators ECM#: Pipe Insulation The existing hot water heating and domestic hot water piping is lacking in insulation not only in the boiler room but also in various locations throughout the facility. Exposed piping in the boiler room in conjunction with the open combustion air increases the energy losses significantly. Un-insulated piping not only wastes energy, but it also allows for un-controlled heating throughout the spaces causing overheating in many areas. Phone: Fax: Unit A Web: Town Hall Page 5 Raynham, MA

7 Exposed boiler room piping Exposed heating & hot water piping Exposed heating pipes Recommendations:. Insulate all the hot water supply and return piping in the boiler room with fiberglass insulation and all service jacket.. Insulate exposed heating supply and return piping throughout the space with Armaflex style open cell rubber style pipe insulation. Seal all joints and fittings with flexible rubber insulation tape. 3. Insulate the domestic hot water piping in the boiler room with fiberglass insulation and all service jacket..

Fiberglass pipe insulation Open cell rubber insulation Rubber insulation tape Phone: Fax: Unit A Web: Town Hall Page 6 Raynham, MA

8 ECM#5: Domestic Hot Water Currently the domestic hot water is supplied from a tankless coil inside the hot water heating boiler. This is a very inefficient way to generate domestic hot water as it causes the boiler to fire at the full rate whenever there is a demand for hot water. There is no storage capacity available as well with this type of system. There is an old 3-way mixing valve on the hot water to reduce scolding from extreme water temperatures from the boiler. There is also a time clock installed on the boiler with a summer / winter switch to help save energy by shutting off the boiler at night. Tankless coil connections Old 3-Way mixing valve Time clock for night setback Recommendations:. Install a new indirect hot water heat exchanger and storage tank for the domestic hot water. Indirect heaters utilize the efficiency of the new boiler to make domestic hot water without the need for another oil burner. The tanks are well insulated and reduce the amount of standby losses.. Install a new 3-way mixing valve to temper the domestic hot water to prevent scolding. Phone: Fax: Unit A Web: Town Hall Page 7 Raynham, MA

9 Indirect hot water heater Piping schematic 3-Way mixing valve ECM#6: Smart Thermostats There are many types of thermostats throughout the facility including some manual and some programmable. Manual thermostats rely on the occupants to set back the temperature daily for night and weekend setbacks. Programmable thermostats can be programmed for automatic night and weekend setback, some of the older thermostats are hard to understand and program properly. New smart thermostats combine the programmability features as well as remote access through the Internet and smart handheld devices. This feature enables easy common scheduling ability as well as remote access for alarms and remote overrides without having to be at the office.

10 Recommendations:. Replace all the manual and programmable thermostats with new Wi-Fi enabled smart thermostats. Handheld apps Full digital display Simple display ECM#7: Plug Load Control Plug load is a name for devices plugged into electrical outlets around the building that not only consume substantial energy but also increase cooling loads due to their heat emissions. The US Department of Energy estimates that office equipment loads comprise about 9% of a commercial building s electrical load exceeded only by HVAC and lighting loads. Typical plug load devices found in this facility included vending machines, mini refrigerators, personal unit heaters, desktop computers, large copiers and printers. Vending machine Personal heaters Phone: Fax: Unit A Web: Town Hall Page 9 Raynham, MA

11 Recommendations:. Install a vending miser controller on the soda machine. Vending machines run /7 maintaining cold beverages, cool snacks and illuminated displays. Most vending machines are not accessed beyond the normal 8 to 0 working hours a day. Vending machine controls incorporate motion sensors to turn them off during unoccupied periods of time the same way occupancy sensors turn off lights. Install a vending miser on the vending machine in the hallway. Over the years this technology has improved so that beverages are maintained at minimum temperatures and compressors are not short cycled.. Install smart power strips at each desk to turn off monitors and personal heaters when computers are not in use. Vending Miser Smart power strips ECM#8: Building Envelope Improvements Air leakage is defined as the "uncontrolled migration of conditioned air through the building envelope". Caused by pressure differences due to wind, chimney (stack) effect, and mechanical systems, it has been shown to represent the single largest source of heat loss or gain through the building envelopes of nearly all types of buildings. Tests carried out by the National Research Council of Canada on high rise commercial and residential buildings, schools, supermarkets, and houses have shown levels of 30 % to 50% of heat loss could be attributed to air leakage. The National Institute of Standards Testing has released similar reports corroborating the Canadian reports. Beyond representing potential for energy savings, uncontrolled air leakage can affect thermal comfort of occupants, indoor air quality through ingress of contaminants from outside and the imbalance of mechanical systems, and the structural integrity of the building envelope through moisture migration. Control of air leakage involves the sealing of gaps, cracks and holes using appropriate materials and systems, to create, if possible, a continuous plane of "air-tightness" that completely encompasses the Phone: Fax: Unit A Web: Town Hall Page 0 Raynham, MA 0767

12 Building Envelope. Part of this process also incorporates the need to "decouple" floor-to-floor, and to "compartmentalize" components of the building in order to equalize pressure differences. Attic Air Barrier Retrofit there is no effective air barrier in place above the drop ceilings at the Lower-Level Attic of the Original Building and the Front Single-Story Shed Roof Addition. Fiberglass batt insulation is installed between the framing members above the drop ceilings; this system allows excessive air and heat loss because fiberglass is air-permeable. The soffits at the eaves of the Front Single-Story Shed Roof Addition are vented; the intention is to direct cold air above the level of the insulation to ventilate the underside of the roof; unfortunately the outdoor air is allowed to leak below the level of the insulation and enter the occupied spaces creating extremely cold surfaces. This outdoor air infiltration contributes to drafts and discomfort at the Front Single-Story Shed Roof Addition; occupants in the Building Department office as well as the office on the opposite side of the front vestibule report these spaces being cold. Attic Bypass Air Sealing the Upper Level and Lower Level Attics at the Original Building have bypasses including access hatches that allow air to leak from the conditioned space of the offices and into the unconditioned attic spaces, which wastes energy. The Upper Level Attic at the Original Building has heating pipes running on the winter cold-side of the existing insulation. The pipes are currently insulated with asbestos and the attic flat is insulated with approximately 3 of vermiculite, another potentially hazardous material. Door Weather Stripping deteriorated weather stripping materials and daylight showing at the perimeter of door systems create direct pathways for unwanted infiltration/ exfiltration. Attic Insulation the existing insulation coverage at the Upper Level Attic in the Original Building 3 of vermiculite insulation is not adequate for controlling heat loss. The vermiculite insulation and asbestos pipe insulation will have to be removed by others prior to any retrofit work being installed in the Upper Level Attic space. Roof Insulation the A-frame roof assembly above the Board of Health Offices is a weak area of the building envelope that allows unwanted heat loss. The existing insulation in place at the flat surface is not effective and there is heating and cooling equipment on the winter-cold-side of the existing insulation, which leads to unnecessary distribution losses and puts the equipment under more stress. As a result, insulation should be installed at the underside of the roof.

17 Wall switch Wireless ceiling sensor Wireless wall switch ECM#3: Hot Water Heating System The existing hot water heating system consists of () cast iron sectional oil fired hot water boiler rated at 66 MBH. The boiler is in good condition and not recommended to be replaced as there would be only a slight improvement in the efficiency. There are outdoor air combustion air ducts that do not have a motorized control damper interlocked with the boiler. There are 5 zones of heat, each served by an individual thermostat, circulator, and zone control relay. There are no outdoor air reset controls; currently the boiler temperature is set at 95F year round. Hot water boiler Combustion air louvers Zone circulators Recommendations:.

Install a new combustion air ducts and dampers on existing louvers. Interlock the dampers with the boiler control to open when the boiler fires. Currently the existing combustion air duct has no damper installed on it, which allows cold air to enter the boiler room year round, this wastes energy and also provides an opportunity for freezing pipes in the winter. High efficiency circulators Draft control damper Combustion air damper ECM#: Pipe Insulation The existing hot water heating and domestic hot water piping is lacking in insulation not only in the boiler room but also in various locations throughout the facility. Exposed piping in the boiler room in conjunction with the open combustion air increases the energy losses significantly. Un-insulated piping not only wastes energy, but it also allows for un-controlled heating throughout the spaces causing overheating in many areas.

Insulate exposed heating supply and return piping throughout the space with Armaflex style open cell rubber style pipe insulation. Seal all joints and fittings with flexible rubber insulation tape. Fiberglass pipe insulation Open cell rubber insulation Rubber insulation tape ECM#5: Domestic Hot Water Currently an electric hot water heater located in the boiler room supplies the domestic hot water. Having this arrangement does allow the larger heating boiler to be turned off in the summer to save energy, but this also does not utilize the boiler efficiency in the winter. There is a trade off here but based on the amount of domestic hot water required, it is a viable solution. There are also unsealed pipe penetrations in the boiler room walls that allow cold air from the boiler room to enter the heated environment that should be sealed up; this is also a fire hazard.

22 ECM#7: Building Envelope Improvements Attic Bypass Air Sealing both the Lower-Level Garage Attic and the Upper-Level Garage Attic have bypasses that allow air to leak from the conditioned space of the garage and into the unconditioned attic spaces, which wastes energy. Gaps at the perimeter of service penetrations and framing components as well as holes in the ceiling surface at the Upper-Level Garage Attic ceiling are unwanted pathways for air transfer between the building and the unconditioned attic. Attic Insulation there are weak areas in the existing insulation at the Lower-Level Garage Attic; the existing insulation depth is not adequate to control heat transfer and gaps in the insulation coverage are allowing unwanted air and heat loss. Infrared imaging from the attic-side identified weak points in the insulation and excessive heat loss into the attic space. Roof Insulation the shed roof assembly above the Dispatch Room is a weak area of the building envelope that allows unwanted heat loss. The existing insulation in place at the flat surface is not effective. There are pipes that run through the space (above the level of the insulation) that must be kept warm.

25 Introduction The Lakeville Police Department is a stand alone one-story facility. Total square footage of the facility is approximately 5,0 and built in 935. An Energy Audit was performed at this facility and reviewed the following: Lighting and lighting controls Heating systems Domestic hot water heating system HVAC controls Building envelope improvements During this process TNT Energy identified several Energy Conservation Measures (ECM s), which have the potential for both electric and gas savings. Energy Conservation Opportunities ECM#: Lighting efficiency upgrades The existing lighting throughout the facility consists of mostly T8 fluorescent technology along with a mix of incandescent lamps. New LED lighting provides an opportunity to reduce the wattage while maintaining light levels and improving light quality. There are several opportunities to upgrade the existing lighting and lighting controls throughout the facility to LED lighting technologies.

27 Wall switch Wireless ceiling sensor Wireless wall switch ECM#3: Heating Systems The facility is heated by () oil-fired furnaces, which provide forced hot air through a ductwork distribution system providing zones of heat for the entire building. While this is not the most efficient means of heating the facility, it would be too costly to replace this system with a hydronic heating system at this point. The existing units are old and are in poor condition, several signs of rust and corrosion. The ductwork distribution system is in poor condition, there are many open seams as well as many sections that are not insulated properly. Leaks in ductwork allow for heated air to enter spaces that are not conditioned and waste energy. Un-insulated ductwork also wastes energy and allows for overheating of areas. Oil furnace Un-insulated ductwork Poorly sealed ductwork Phone: Fax: Unit A Web: Police Department Page Raynham, MA

28 Recommendations:. Replace the existing oil furnaces with new higher efficiency furnaces. Install new concrete pads for the furnaces to set on so that moisture does not come in direct contact with the sheet metal housings.. Seal up all the exposed ductwork connections with duct sealer. 3. Insulate all exposed ductwork with fiberglass duct insulation. New oil furnace Fiberglass duct insulation Duct sealant ECM#: Domestic Hot Water Currently there are () electric hot water heaters that supply domestic hot water to the facility. This is the most efficient way to provide domestic hot water to this facility based on the design and use of the building.

30 Recommendations:. Replace the programmable thermostats with new Wi-Fi enabled smart thermostats. Handheld apps Full digital display Simple display ECM#6: Building Envelope Improvements Attic Air Barrier Retrofit there is no effective air barrier in place above the left-side of the building (view from Bedford Street). There is a drop ceiling and vinyl-faced fiberglass insulation laid over the bottom chord of the truss system and suspended by strapping. This system is in place below both the original shed roof at the front of the building and the smaller rear A-frame addition section. This construction allows excessive heat loss and air exfiltration and as a result wastes energy. An effective and continuous air barrier must be installed to separate the unconditioned attic space from the heated and occupied spaces of the building. Attic Insulation the existing vinyl-faced fiberglass blanket insulation in place above the drop ceiling at the left-side of the building is not effective. The missing air barrier degrades the thermal performance of the air-permeable insulation and the existing fiberglass material is not adequate for thermal transfer. Door Weather Stripping deteriorated weather stripping materials and daylight showing at the perimeter of door systems create direct pathways for unwanted infiltration/ exfiltration. Attic/ Roof Insulation at the Right-Side of the Building the right-side of the building (view from Bedford Street) has multiple roofs constructed over earlier roof systems. Effectively retrofitting this side of the building will require coordination between structural engineers, architects, roofers and insulators. The general approach recommended at this side of the building is to install insulation above the level of the HVAC equipment and ductwork that runs above the occupied spaces of the building, but at the smallest possible surface area. Insulating at the smallest possible surface area is important for energy efficiency and also because of the impact that insulating vertical surfaces will have on the overall performance of the building. If insulation is installed at the exterior roof line (the largest possible surface area), the walls will all need to be insulated above the level of the occupied spaces and below the exterior Phone: Fax: Unit A Web: Police Department Page 7 Raynham, MA

31 roof surface. If the walls, especially at the front of the building are left un-insulated the value of the insulation at the roof will be diminished due to the heat loss through the walls. Understanding the structural impacts of the retrofit work will be important to deciding the best insulation approach. Roofing as mentioned above the roofers will be an important part of the solution at the right-side of the building. At the left-side of the building, the roofers do NOT need to add insulation at the exterior side of the roof. All of the insulation work at the left-side of the building will be done below the roof line, which is preferred because it is a smaller surface area. It is assumed that others will create a water-tight roof assembly above the left-side of the building, so the retrofit insulation system is not damaged by water leaks. Roof Ventilation at the top of the Left-Side Shed Roof roofers should install passive ventilation strips at the top-side of the shed roof at the front left-side of the building. This may require an overhang to be constructed. The ventilation at the top of the shed roof combines with the existing ventilation at the eaves to create an effective intake and exhaust ventilation system. Window Replacement the window systems in the building are in poor operational condition. It was reported during our site visit that many windows do not open or close properly. Unfortunately, a lower cost retrofit approach is not practical at these window systems and replacement is the only appropriate intervention. Missing insulation Exterior doors leaking Missing air barrier Recommendations:. Attic Air Barrier Retrofit a. Block, Seal On Flat install Dow Thermax Sheathing rigid insulation as the primary air barrier layer of the assembly across the entire attic flat surface (at the bottom truss chord).

Smart power strips ECM#5: Building Envelope Improvements Attic Air Barrier Retrofit there is no effective air barrier in place above the drop ceiling areas of the building, including the Pool Room, Computer Room, Veterans Office, Staff Break Room, Staff Offices, Director s Office, Kitchen and Main Entry Area. Fiberglass batt insulation is installed at the bottom chord of the truss system above a drop ceiling. This system allows excessive air and heat loss because fiberglass is air-permeable. The soffits at the eaves of the building are vented; the intention is to direct cold air above the level of the insulation to ventilate the underside of the roof; unfortunately the outdoor air is allowed to leak below the level of the insulation and enter the occupied spaces creating extremely cold surfaces. This outdoor air infiltration contributes to the very cold surfaces at the drop ceiling, which is likely contributing to discomfort for occupants. The heating and cooling ductwork runs from the catwalk mechanical space above the level of the fiberglass insulation before reaching registers in the occupied spaces. As a result, the distribution loss of heat from the ductwork is directly under the roof deck surface and contributes to the snow melt and ice dam problems at the building. Door Weather Stripping deteriorated weather stripping materials at the bottom of the single doors and daylight showing at the perimeter of door systems create direct pathways for unwanted infiltration/ exfiltration.

39 Missing air barrier Recommendations: 6 Degrees above the hung ceiling Missing weather stripping. Attic Air Barrier Retrofit a. Block, Seal install Dow Thermax Sheathing rigid insulation as the primary air barrier layer of the attic assembly above the level of the drop ceiling. Seal all seams and joints with sheathing tape or polyurethane foam sealant. b. The areas with the vaulted drop ceilings at the Cafeteria and Great Room are excluded from the scope of work.. Door Weather Stripping 3. Ice Dams and Heat Loss at the Top of the Building the recommended retrofit measures will NOT solve the ice dam problems. After the retrofit recommendations are installed, the heat from the ductwork below the level of the roof system will continue to melt the snow on the roof and cause ice dams. The retrofit recommendations are intended maintain the heat in the within the occupied spaces as best as possible and improve comfort issues with infiltration associated with the soffit vents. Without a complete re-construction effort of the building a major undertaking solving the problems with the ice dams is not possible.
