2.3 HVAC System

Each unit at Golden West Senior Living has hot water baseboard heating controlled by a pneumatic zone valve and in-unit non-programmable thermostat. Cooling is provided by packaged terminal air conditioners (PTAC) mounted in walls and windows. The mezzanine building also has supplementary electric heat convectors for the assisted living units. All three buildings are served by central hot water and chilled water plants located in the central tower mechanical room.

2.3.1 Hot Water Plant

Hot water serves baseboard in the units and common areas as well as hydronic coils in the central tower air handing unit (AHU), dining hall rooftop unit (RTU), and fan coils in the penthouse of the central tower. The hot water plant consists of one forced draft and four natural draft hot water boilers in primary-secondary configuration. The total boiler plant is rated 12,409 MBH input and 9,322.4 MBH output at sea level conditions (breakdown of each boiler capacity can be found in Table 6). The boilers have an estimated manufacture date of ranging from 1965 for the large original units, 1983 for the three smaller non-condensing units, and 2017 for the recently installed forced draft unit. Piping in the boiler room has fiberglass insulation in most areas. Some oversizing and standby losses associated with the boilers necessitated assuming an average boiler efficiency of 75% in the DOE-2 energy model to calibrate the model to historical utility data.

There is a primary hot water loop in the mechanical room which has a constant volume heating water pump and a shell and tube heat exchanger serving the secondary hot water loop connected to building heat. Each of the boilers has its own secondary loop with a dedicated constant volume pump. Another secondary loop with a shell and tube heat exchanger serves the glycol snowmelt system. The snowmelt system is manually operated by maintenance to serve 3890 sqft of walkways and entries around the building.

2.3.2 Chilled Water Plant

The chilled water plant consists of a two-circuit reciprocating chiller with 50 tons of capacity. Each circuit has 25 tons of capacity and three stages of cooling. The unit is manually shut down seasonally, and the on-board controls maintain 50°F discharge temperature. The condensing unit which serves the chiller is located on the west side of the building. The system controls showed a low pressure lockout of compressor 1 at the time of audit. Chilled water is circulated by two base mounted constant volume pumps operating in lead / standby mode.


16

2.3.3 Air Handlers and Ventilation

There is an air handling unit (AHU) in the central tower which serves the first floor common areas. It is a variable air volume (VAV) unit with hydronic reheat coils in the VAV boxes. A manual outside air damper is controlled by maintenance to provide ventilation to this system. The AHU is equipped with a hydronic coil served by the hot water and chilled water plants.

The dining hall is conditioned by a rooftop unit (RTU) with a hydronic coil for heating and cooling. Two (2) three-way valves are operated by pneumatic controls to provide hot or chilled water from the central plants. The RTU is controlled by two separate heating and cooling thermostats located in the dining hall.

The central tower penthouse common areas are heated by hot water convectors as well as horizontal fan coils in some of the meeting rooms. The fan coils are operated by pneumatic controls and it does not appear that all of the units are operational. Cooling in the penthouse is provided by PTACs throughout the space.

There is a make-up air unit (MAU) in the mechanical penthouse of the central tower, but the unit has not been operational for over 15 years. There is no mechanical ventilation to any of the residential hallways of the three buildings. Ventilation and exhaust is currently provided in the residential units by exhaust in the bathrooms and kitchens and operable windows. Exhaust in the central tower and mezzanine building are provided by rooftop exhaust fans while the south tower is served by individual bathroom exhaust fans. Common area exhaust is provided to the public bathrooms.

2.3.4 Domestic Hot Water

Domestic hot water (DHW) is provided by a dedicated boiler plant with three natural draft boilers on a primary loop with two constant volume pumps that run in lead/standby mode. The boilers are single stage, non-condensing units with a combined capacity of 1,448 MBH input and 1,162.4 MBH output at sea level conditions. Two of the boilers were manufactured in 2010 while the third is from 1979. The boiler plant connects to a shell and tube heat exchanger which serves three (3) 250 gallon storage tanks using two (2) constant volume pumps in lead/standby. There are two (2) 1/6 HP recirculation pumps serving each of the buildings that run continuously in lead/standby configuration. Piping for the domestic hot water system has fiberglass insulation in most areas.

2.3.5 Commercial Kitchen HVAC and DHW

There is a commercial kitchen on the first floor of the central tower with a connected dining hall for residents. The commercial kitchen has three exhaust hoods; one serving the front of house, one serving the back of house, and the third serving the dishwashing area. Two of the exhaust fans and two makeup air units are located on the roof, and the third exhaust fan is located in the garbage room and terminates sidewall.

Two walk-in refrigerators and one walk-in freezer are located in the kitchen prep area. Both refrigerators have holding temperatures of 31°F, while the freezer is set to 7°F. Each unit has a dedicated evaporator with a condensing unit located in a locked area on the east side of the building near the loading dock.

There is also a dedicated shell and tube heat exchanger with 1/3 HP circulation pump that provides higher temperature DHW for the commercial kitchen. This heat exchanger is still served by the central hot water plant in the mechanical room. A 1/6 HP recirculation pump for the kitchen runs on an aquastat set to 160°F which causes it to operate continuously.

2.4 Equipment Testing and Records

Flue gasses were analyzed for the domestic hot water boilers, but the space heating boiler plant is drained down annually and therefore couldn’t be tested. The heating system is drained each summer because the distribution piping begins leaking when the system cools down. Combustion gas analysis of the operational boilers can be found in the table below along with nameplate efficiency ratings for the space heating equipment. Storage tank and boiler temperature set points are also included:

3.6 Central Heating Plant Upgrade to High Efficiency Condensing Boilers

Existing Condition:

Golden West Senior Living has three (3) operational natural-draft boilers and one (1) assisted-draft hot water boiler providing heating water to all three of the buildings. The hot water feeds baseboard radiators in the units and common spaces as well as hydronic coils in the first floor air handling unit (AHU), first floor VAV boxes, and dining hall rooftop unit (RTU). Hot water piping is connected to a makeup air unit in the central tower, but the equipment has not been operational for over 15 years. The natural draft boilers are Weil-McLain units, the largest of which is original to the building while the two smaller units are from approximately 1983. The Raypak power vent boiler was installed in the last couple years. The total operating plant capacity is 12,409 MBH input and 9,322.4 MBH output at sea level conditions.

There are three (3) parallel 3 HP base-mounted, constant-volume circulation pumps that move heating water through the primary shell and tube heat exchanger and to the equipment in the central and south tower residences. The pumps currently operate lead/standby with two pumps running at a time. Two (2) parallel 1-1/2 HP base-mounted, constant-volume circulation pumps are also connected to the load side of the heat exchanger and serve the mezzanine building, central tower AHU, VAV boxes, and dining RTU. The pumps operate lead/standby with one pump running at a time. These pumps operate continuously during heating season. The boilers are staged to maintain a constant temperature of 180°F in the primary heating loop during heating season from October to May, and a single 2 HP base-mounted pump circulated water in the primary loop continuously. Each boiler has a dedicated boiler pump that engages when the associated boiler is engaged.

The boilers are operated from individual controls set to 180°F according to maintenance. Some of the set points were not able to be verified because power was not supplied to the boiler plant in the cooling season and the system had been drained. There is an outside air lockout on the largest boiler (B-1) which only enables when outside air temperatures drop below 25°F. The forced-draft boiler (B-4) acts as the first stage, and the two smaller natural draft boilers (B-2, B-3) are staged using a Tekmar 264 Boiler Controller per the following reported controls:

• Heating water supply temperature setpoint of 180°F in the primary loop.

• No outside air reset currently used

• Boilers are manually shut off seasonally

The existing combustion air intake is located on the north wall of the mechanical room. The boilers are currently venting to a large vertical masonry stack going up to the roof of the building.

Efficiency Measure:

The natural draft boilers have surpassed their life expectancy. It is recommended to replace the three older space heating boilers according to the engineered design drawings that will be released in a separate addendum. The new system should include the following energy saving measures:

• High efficiency condensing hot water boilers

• New parallel high efficiency pumps with variable frequency drives for hot water distribution.


28

• A new boiler control system to operate the boilers and pumps with the following sequence of control:

o Enable boilers when the outside air temperature falls below 62 F (adj.). Disable boilers when outside air temperature rises above 65 F (adj.).

o The HWST Setpoint shall be reset according to a linear outdoor air reset schedule in which the design hot water temperature, 180 F (Adj.), is delivered at 5 F (Adj.) outside air temperature and lower, and 120 F (Adj.) HWS is delivered at the high outdoor air temperature of 60 F (Adj.). This reset shall be optimized to deliver 120F water at the furthest most radiator.

• Insulate all exposed hot water piping.

Improvements to Operations and Maintenance:

New boilers will extend the lifecycle of the plant, and will reduce the number of maintenance and repair work orders.

Pricing and Site Specific Installation Notes to Contractor:

Price project with current boiler plant size. Before final equipment selection, contractor shall be responsible for load calculation and equipment sizing per specifications. It should be noted that the contractor is ultimately responsible for verifying site conditions. Contractor will be responsible for issuing a deduction if plant has been reduced significantly in size.

The recommended actions for the central plant upgrade to condensing boilers is predicted to save $14,136 each year, giving this measure an SIR of 1.0.

3.7 Domestic Hot Water Plant Upgrade to High Efficiency Condensing Boilers

Existing Condition:

Golden West Senior Living has three (3) natural-draft boilers providing domestic hot water (DHW) to all three of the buildings and the commercial kitchen. The boilers are Burnham units, one of which was manufactured in 1979 while the other two were installed in 2010. The two newer units have 460 MBH input capacity each, while the older unit has 528 MBH input capacity. Total operating plant capacity is 1,162.4 MBH output at sea level conditions.

The boilers serve two shell and tube heat exchangers; one for the commercial kitchen and one for the residential units. The boilers are staged to maintain a constant temperature of 150°F in the boiler loop at all times.

The heat exchanger for the residential units is connected to three large storage tanks with approximately 500 gallons capacity each. The boiler side of the heat exchanger has two (2) parallel 3/4 HP in-line, constant-volume circulation pumps that operate continuously to provide heating water to the heat exchanger. There are also two (2) 1/6 HP inline circulation pumps on the tank side of the heat exchanger that run continuously in lead/standby mode. A three-way valve in the boiler loop is used to control DHW temperatures, and the gauges at the storage tanks were displaying an average storage temperature of 127°F. There are also 1/6 HP recirculation pumps for each of the three buildings that tie into the system at the return to the heat exchanger.

The commercial kitchen heat exchanger has a single 1/3 HP heat exchanger pump that runs continuously and a single 1/6 HP DHW recirculation pump that is controlled by an aquastat. The aquastat is set to maintain 140°F return water to the heat exchanger.

Efficiency Measure:

One of the natural draft boilers has surpassed its life expectancy, and the heat exchangers appear to be in poor condition. Replace the existing boiler plant and heat exchangers according to the engineered design


29

drawings that will be released in a separate addendum. The new system should include the following energy saving measures:

• High efficiency condensing hot water boilers for domestic hot water

• Insulate all exposed hot water piping.

• Install, test, and balance a thermostatic mixing valve to temper the domestic hot water to 120°F. The domestic hot water storage tanks should be maintained at 140°F to prevent the risk of Legionella.

• New recirculation pumps for each building equipped with EC motors and able to automatically adapt its setpoint to adjust to actual system characteristics, sized to meet the calculated pressure loss of the longest piping run.


New boilers and pumps will extend the lifecycle of the plant, and will reduce the number of maintenance and repair work orders in the near future. Elimination of the heat exchangers should also decrease maintenance requirements.


Price project with current boiler plant size. Before final equipment selection, contractor shall be responsible for load calculation and equipment sizing per specifications. It should be noted that the contractor is ultimately responsible for verifying site conditions. Contractor will be responsible for issuing a deduction if plant has been reduced significantly in size.

The recommended upgrades of the DHW system are predicted to save $4,189 each year, giving this measure an SIR of 1.6.

3.8 Hot Water Pipe Insulation

Existing Condition:

There are stretches of hot water piping in the mechanical room that were not insulated. The following table shows the approximate lengths and diameters of hot water piping in the mechanical room:

Pipe Size (in. dia)

Pipe Length

¾” 50 feet

1” 100 feet

2” 100 feet

4” 200 feet

6” 100 feet

Efficiency Measure:

All hot water piping accessible in the mechanical room should be insulated with 1” fiberglass pipe insulation.


Insulation of piping will reduce energy waste and also increase comfort in mechanical spaces for maintenance teams working on equipment.


The Contractor shall be responsible for the design and construction of the installation in its entirety, and shall secure the services of qualified professionals as required to complete this scope of work.

3.9 Replace Dining Room Rooftop Unit (RTU)

Existing Condition:

The dining hall in the central tower is heated and cooled by a single rooftop unit (RTU) located on the north side of the dining hall roof. The RTU is equipped with a 5 HP blower and a hydronic coil connected to the hot water and chilled water plants. The unit is operated by pneumatic controls connected to two separate heating and cooling thermostats in the dining hall. The thermostats operate three-way valves at the RTU that supply hot or cold water based on demand.

The RTU is designed to supply ventilation air to the dining hall via an outside air damper that mixes return air and ventilation air. However, the outside air damper appeared to be permanently closed which eliminated any ventilation functions for the system.

Efficiency Measure:

The RTU has surpassed its life expectancy and is not operating as designed. Replace the existing RTU according to the engineered design drawings that will be released in a separate addendum. The new system should include the following energy saving measures:

1. Economizer cooling with 100% outside air when ambient temperatures outdoors are at least 10°F below indoor temperatures and there is a call for cooling

2. Demand control ventilation with CO2 sensors in the dining hall and a motorized damper on the outside air louver of the RTU.

3. DX cooling with a minimum EER of 12.

4. Incorporate a zone space night time setback of 80F (adj) for cooling.


The new equipment will provide an operational system that can supply adequate ventilation air to the space. In addition to the equipment being newer, thereby lowering the number of services calls, the equipment will offer a higher level of control and reduced energy consumption.

Benefit to Residents:

The increased control of the RTU will provide for a more comfortable area in the dining hall and improve ventilation to the space.


Price project with current RTU size. Before final equipment selection, contractor shall be responsible for load calculation and equipment sizing per specifications. It should be noted that the contractor is ultimately responsible for verifying site conditions. Contractor will be responsible for issuing a deduction if plant has been reduced significantly in size.

4 Efficiency Measures Not Recommended 4.1 Replace Pneumatic Thermostats with Programmable Electronic

Thermostats and Remove Air Compressor

Existing Condition:

The baseboard heating throughout the buildings are controlled by old pneumatic thermostats and two way control valves. Additionally, the VAV boxes on the first floor of the central tower are also controlled by pneumatic thermostats. The pneumatic thermostats don’t have any programmable functionality. Control for the pneumatic thermostats is provided by an air compressor in the mechanical room with a 5 HP motor.

Efficiency Measure:

Replace 372 wall thermostats with electronic programmable thermostats and install compatible zone valves. Ensure appropriate power requirements of the thermostats are met. Once all pneumatics are removed, remove the air compressor in the mechanical room.

The contractor shall provide simplified training materials to teach management and residents how to operate and program their new thermostat.


4.2 Install Solar Photovoltaics

Existing Condition:

The buildings at Golden West Senior Living all have flat roofs and no solar PV on site. Currently, the only electrical generation on site is from a backup generator located in the vault on the west side of the building.

Efficiency Measure:

All three buildings of Golden West have flat roofs and some area suitable for solar PV. The mezzanine building has exhaust fans along the centerline of the roof, but has approximately 30% of roof area available around the edges for PV panels (2,000 sf). The central tower has quite a few roof penetrations, making it difficult to find room for PV. There is a small 600 sf area in the center that may be suitable for PV. The south tower has the most room available for solar. Excluding the existing pathway and the shadow cast by the mechanical penthouse, approximately 50% of the roof area is available for PV (3,700 sf). These potential areas can be seen in the photos below as shaded green areas.

The north tower and central tower main roofs were both installed in 1987 and are nearing the end of their expected life. To ensure that roof replacement is not needed during the life of the solar array, roof replacement should be performed prior to installing solar. The roof of the south tower was replaced 5 years ago, so no replacement is necessary.

The total available area was evaluated with setbacks and array spacing, and an available system size of 63 kW was estimated. Typical parameters were applied in PVWatts to determine a potential energy production of 92,889 kWh/year worth approximately $9,029 per year.


32

The new solar equipment will not provide any improvements to operations and maintenance since the solar PV would be a new system. However, the new roof will decrease the chance of roof maintenance or leak repairs. Preventative maintenance of the solar array should be performed annually at least to ensure adequate electrical production.


The solar energy production would not significantly affect residents, but would decrease the carbon footprint of the building.


The contractor is responsible for verifying possible solar deployment areas and ensuring code required offsets from building elements are maintained. Structural capability of the roof should be evaluated as part of the development process to ensure the roof can carry the additional load.

5 Recommended Health and Safety Measures 5.1 Replace Non-Functional or Low Flow Exhaust Fans

As part of the audit, all of the unit exhaust fans were tested for functionality and air flow. Fifty-four (54) of the fans had flows so low that they were unreadable. This was due to low fan airflow, inoperable equipment, or sealed exhaust grilles. All of the exhaust fans in the South Tower were drawing less than 50 cfm, the code minimum bathroom exhaust airflow for switch operated exhaust fans. There are 34 units in the Central Tower and Mezzanine where the bathroom exhaust was drawing under 20 CFM, the code minimum bathroom exhaust for constantly operating exhaust. This can create mold and air quality health and safety issues. For the South Tower, the fans should be replaced with functioning Energy Star exhaust fans and measured to verify they are removing an appropriate amount of air from the space. For the Central Tower and Mezzanine, rooftop exhaust fans should be replaced with high efficiency fans sized for appropriate exhaust air flow from each units. In addition, grilles that are broken or sealed should be replaced. Please reference Appendix D for a listing of the specific unit numbers where new exhaust fans should be installed.

Switch operated fans are available with efficacies above 13 cfm/W, so it is advised that a fan with an efficacy of at least 10 cfm/W be selected. Exhaust fans should be replaced without change to existing ventilation strategy. If current duct configuration is not code compliant, any issues should be brought to the attention of the owner.

The new switch operated equipment should include the following:

• ENERGY STAR® rated exhaust fans • In general, fans should be rated at 75 CFM. If the selected product varies from this, secure approval

from the owner and commissioning agent (if applicable). • Properly seal the fan with caulk or other similar material to inhibit air leakage to the exterior of the

thermal envelope of the building. • Always reuse existing duct work. If instances are found where existing duct infrastructure is not code

compliant, bring to the attention of the owner. • All new ductwork routing shall be approved by the Owner for locations and enclosure finishes.

Replacing the exhaust fans with Energy Star qualified fans can save $2-5/fan each year. While this measure would only have an SIR of 0.1, it would produce some energy savings.

5.2 Mildew and Mold Remediation

Existing Condition:

100% of the units at Golden West Senior Living were visually inspected for mold. Two units were found to have mold and/or mildew present, with other units showing initial signs of mildew.

Health and Safety Measure:

All mold needs to be remediated by the property owner prior to beginning any additional construction. Mildew, while it poses a milder health risk than mold, can turn in to more toxic mold if not properly addressed. Suggestions for remediation of both mold and mildew are presented below.

All areas of mold and/or mildew should be investigated to determine the moisture problem before any repairs are made. Address all necessary steps to ensure the moisture problem has been fixed before replacing any gypsum board, wood, insulation, or flooring. A moisture meter can be utilized to ensure the surfaces affected match other adjacent surfaces.

If the surface is non-porous – such as concrete, some wood, plastics, and/or metal – mildew and mold should be removed utilizing non-toxic chemicals. For O&M operations the 3 best ways to clean the mold and mildew


36

are utilizing hydrogen peroxide, vinegar, and baking soda. Bleach and ammonia should only be used if it is necessary. Also consider utilizing a treatment on the surface once completed like a Foster Full Defense Fungicidal Protective. For caulking in showers and tubs, if the cleaning techniques are not effective, it is best to remove and replace the existing caulking. Make sure to choose a bathroom-appropriate caulk that is resistant to mold and mildew.

All porous materials such as paper faced gypsum board showing signs of mold/water damage should be removed and replaced. The removal process should involve the use of an encapsulate to seal the mold byproducts and help prevent them from becoming air born. Dust should be kept a minimum and any dust produced that cannot be easily wiped up should be vacuumed with a HEPA Vacuum. All remaining surfaces should be wiped down utilizing a clean cloth and one of the previously described chemical compounds and treated with an encapsulate (one example is Fosters Full Defense Fungicidal Protective). All debris should be disposed of in heavy duty 6mil trash bags and sealed before they leave the work area.

Larger work areas that surpass the trigger level of 10 square feet of mold contamination shall be placed into a containment under discernable negative pressure. The negative pressure shall be provided by a negative air machine equipped with a HEPA air filter, pre-filter and discharge directly outdoors. The containment shall be made utilizing a single layer of 6mill poly plastic sheeting and a zipper door if necessary. The Negative Air Machine and other remediation tools shall be inspected by maintenance staff prior to entering the property to ensure that there is no signs of visible dust and or debris that could further contaminate the space from previous remediation projects.

Well-functioning bathroom exhaust fans and resident education on proper ventilation, such as running the bathroom fan or opening the bathroom window after a shower, and in-unit moisture management, such as wiping away excess water around the sinks, will help prevent mildew and mold growth in the units.


The residents will benefit from the improved health conditions in their units.

Pricing and Site Specific Notes to Contractor:

Contractor shall provide pricing for each stage of removing and replacing caulking throughout the bathrooms in each unit, and replacing the damaged boards underneath the kitchen/bathroom sinks of each unit with damage. Please see the attached Mold bid form in Appendix C.

5.3 Install Thermostatic Mixing Valves (TMV)

Currently, there is a three way valve controlled by the pneumatic system to maintain domestic hot water temperatures. In the case of a controls failure, there would be no functioning thermostatic mixing valve on the domestic hot water system, presenting a scald risk to residents. The Contractor shall install, test, and balance a new TMV to ensure safe water temperatures to the building.

5.4 Replace Make-Up-Air Unit (MAU)

Existing Condition:

The central tower has one (1) make-up air unit (MAU) located in the mechanical penthouse on the roof, but the unit has not been operational for at least 15 years. The unit was designed to provide tempered fresh air using a hot water coil connected to the boiler plant via a shell and tube heat exchanger. The MAU side of the heat exchanger was likely designed to operate with a glycol mixture to avoid freezing the heating coil. A single 1/4 HP pump is in place on the MAU side of the heat exchanger to circulate hot water to the coil.

The MAU is designed to supply ventilation air to the corridors and elevator lobbies through wall mounted grilles near the elevators and near the stairs at each end of the building.


37

Efficiency Measure:

The MAU has surpassed its life expectancy and has been out of service for many years. Replace the existing MAU according to the engineered design drawings that will be released in a separate addendum. The new system should include the following energy saving measures:

5. Units shall be controlled to maintain a constant 68°F in heating and 78°F in cooling.

6. Heat pipe for heat recovery from nearby roof exhaust.

7. Indirect evaporative cooling of the exhaust air

8. The new system shall be equipped with a VFD to control the fan motor. Program the VFD to supply the scheduled airflow in cooling mode, and during day time in the heating season (6AM-10PM). During the heating season, reduce night time (10PM-6AM) fan air flow to 0.06cfm/sf.

9. Insulate all exposed existing and new ducting where accessible.


The new equipment will provide an operational system that can supply ventilation air to the building. In addition, the newer equipment will have a higher level of control and reduced energy consumption.


The units will provide improved ventilation to the hallways while also maintaining comfort in the common areas.


Price project with current MAU size. Before final equipment selection, contractor shall be responsible for load calculation and equipment sizing per specifications. It should be noted that the contractor is ultimately responsible for verifying site conditions. Contractor will be responsible for issuing a deduction if plant has been reduced significantly in size.
