Passive House

Passive building is a set of design principles for attaining a rigorous level of energy efficiency while also creating comfortable indoor living spaces.

Passive house designed buildings follow 5 building-science principles:

​1. Continuous insulation throughout the entire envelope without thermal bridging

2. Airtightness to prevent infiltration of outside air and loss of conditioned air

3. High-performance windows and doors.

4. Balanced heat and moisture-recovery ventilation

5. Minimal space conditioning
