Exhibits


Chimney

Entry Way

Sun Room
Exhibit A
1959 Bungalow with Attached Garage
- Chimney: Openings for flue and combustion air creates a very large area of thermal loss, both through thermal bridging in areas with no insulation and air leakage. This is suspected to be a large area of energy loss.
- Entry Way: Change in thermal pattern after applying testing pressure showed potential connection between house and garage.
- Heated Sunroom: Although not included in the Heat Loss Map, this area is all glass and includes an older patio door that showed strong leakage at weather-stripping during testing. Moreover, the connection of sunroom framing to the house appears to not be fully airtight.


Attic Hatch

Garage Wall
Exhibit B
2011 2 Storey with Attached Garage
- Attic Hatch: Large leakage area noted around the attic hatch and the trim that surrounds it. This would allow large amounts of warm humid air to pass during the winter, which can lead to dampness that promotes mould growth as suspected on the insulation blocking around the opening.
- Garage Wall: Suspected poorly sealed connection between wall and floors that separate the house from the garage. This would result in additional energy loss and risk of durability issues.


Garage Wall

B-Vent

Fireplace

Living Room
Exhibit C
1976 2 Storey with Attached Garage
- Garage Wall: Wall between the house and the garage is showing areas of air leakage. Under normal conditions, this warm air will travel up the plumbing and electrical penetrations, laundry vent and into the garage attic.
- Fireplace: Replacement gas insert showing strong leakage around the edge—indicating poor seal of new unit to the existing chimney. Combined with warm house air leaking up the chimney, this creates a greater level of heat loss.
- Mechanical Vent: Metal B-vent is unsealed and strongly leaking. Warm house air will rise up this chase wall, which is unsealed at the attic level. Plastic side venting furnace vents also appear to be unsealed.
- Living Room: Poorly fit insulation and heavy thermal bridging creates a cold area along the living/dining room ceiling. This area shows suspected air leakage after testing the air pressure applied.
Note: HEAT Maps show red as hot, and blue as cold. The handheld IR images show white and yellow as hot, and purple and blue as cold.
