Passive House concept
The Passive House standard requires buildings to use at least 80% less energy than a comparable conventional building.
The Passive House standard requires buildings to use at least 80% less energy than a comparable conventional building, so air tightness is a must. The structure must be completely sealed against any air infiltration, at the same time preventing conditioned air from escaping. This means Building Teams must employ multiple layers of insulation in the walls, roof, and flooring, plus continuous air barriers and reliable windows and doors.
Once the building is completely sealed, a number of techniques can be engaged to regulate the temperature.
Passive house design strategies
- Natural Ventilation
- Ventury Effect
- Shading
- Wind Towers
- Courtyard Design
- Earth Air Tunnels
- Evaporative Cooling
- Passive Down Draught Cooling
- Roof pool
- Trombe wall
