The Passive House Method
The Passive House Method is the standard bearer for high performance design and construction around the world. It is grounded in building science, advanced energy modeling, and this following suite of design principles:
- High Performance Windows and Doors
To capture solar gains, dramatically reduce heat loss, and maintain the moderate interior surface temperatures vital to occupant comfort.
- Continuous Insulation
- A warm sweater to wrap the building’s four walls, foundation and roof, free of gaps or “thermal bridges”.
- Airtight Envelope
- To eliminate chilly drafts and moisture-bearing air leaks into building assemblies.
- Balanced Fresh Air Ventilation
- A high performance H/ERV ventilation system supplies filtered fresh air, exhausts stale air, and recovers heat and humidity.
- Passive Solar Management
- To exploit the sun’s energy in the winter and shield from it during the summer.
