The Home’s Magic Membrane
The building envelope is the physical separator – the walls, roof and foundation – between the inside and outside of the building. The design, configuration and performance of the building envelope have a direct impact on your comfort, home heating bill and home maintenance costs. The envelope is also the longest-lasting and most difficult piece of a home to change, so it should be a top priority when building.
Energy-Efficiency in New Homes
- Insulation: Proper insulation keeps heat inside when it’s cold outside, and keeps it cool inside when it’s warm outside
- Good Windows: Energy-efficient windows, doors and skylights can reduce your home energy costs
- Ventilation: Highly efficient and airtight homes will typically have a heat recovery ventilator (HRV) that provides abundant fresh air into the home while minimizing heat loss
- Air Leaks: Airtightness (sealing) is critical to reduce leakage of air between indoors and out, this includes things like caulking and weatherstripping in existing homes
