To meet the strict criteria set forth by EnergyStar and the EPA, the house features many unique features to make it as tight a construction as possible, with only controlled air-infiltration.
All plywood joints, gaps, penetrations, top and sill plates, and other openings in the sheathing are sealed with expanding polyurethane foam insulation to make the building envelope air-tight.
All exterior walls feature BIBS system, blown-in insulation. Not only does this system offer a thermal value of R-23 (versus the conventional R-19 for an exterior wall), but it fills any voids or crevices around electrical boxes and pipes, normally left by conventional insulation.
Roof insulation is R-30 Batt, covered with an additional layer of blown-in cellulose insulation, level with the ceiling rafters (12” depth). This provides additional insulation at the top of the thermal envelope, where most heat is lost, for a total value of R-38 and fills any cracks and voids left by the batts, such as around IC housings, ductwork and exhaust fans. The cellulose insulation is made from recycled materials and is bio-friendly.
A combination of these systems can be implemented to meet the client’s energy saving goals.
