E. Tile Ceiling:

installed in the PVC intake ductwork at each fan to provide additional air to flow into the fans. Both fans were installed 30 years ago.

  1. 1. The ceiling in the storage room is falling, apparently due to the lack of an attic vapor barrier and will need to be replaced.

F. Grilles and Diffusers:

G. Attic Vapor Barrier:

  1. The existing grilles in the storage room are damaged and falling out of the ceiling.
  2. Existing supply diffusers do not have dampers accessible from below the attic insulation envelope.
  3. Existing exhaust grilles and return grilles have noticeable dirt and debris buildup on the face of the grilles, and do not have dampers accessible from below the attic insulation envelope.
  4. The ventilated attic has a layer of batt insulation with a foil face between the bottom of the roof trusses. There are large gaps in the insulation, so it does not function as a vapor barrier.

H. Mechanical Room:

  1. Two natural draft water heaters are existing in the mechanical room. Water heater WH-1 is a 50 gallon, 40 MBH water heater that was installed in 2019.
  2. WH-2 is an 84 gallon, 199 MBH, propane heater converted to natural gas. This water heater is 30 years old.
  3. Unit heater UH-1 is a 200 MBH, natural gas unit heater that is 30 years old.
  4. The mechanical room has two louvers to allow for combustion air to the water heaters, unit heater, and duct furnace. These louvers total 8 square feet.

1. Emergency Generator:

  • Live Feed Room:
  • The existing emergency generator located outside the building is 30 years old.
  • The Live feed room has a 4 kW electric heater in the wall that is 30 years old.
