The house construction consists of concrete strip footing foundation and wall, 38 x 89 (mm) wood frame walls above grade, and wood truss and joists. The exterior siding of the house is clad with wood siding and asphalt shingle roofing.
The scope of the retrofits [for each unit] includes, but is not limited to:
- Demolition of existing envelope including wood siding, substrate, existing windows and doors, asphalt shingles and roof insulation;
- Demolition of existing furnace; and mechanical upgrades including new oil fired furnace and new heat recovery ventilator (HRV) system;
