Your 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 has a direct impact on your comfort, home heating bill and your 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.
An Energy-efficient New Home Depends On:
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 reduce your home energy costs by 7 to 12%.
Ventilation: New homes built to EnerGuide 80 and above will usually 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 reduces leakage of air between indoors and out. This includes things like caulking and weatherstripping in existing homes.

A high-performance, energy-efficient building envelope can save up to 40% of your home heating costs.
