Passive House Standard

The Passive House concept represents the highest voluntary energy standard. It results in energy efficient buildings that require very little energy for space heating and cooling. A Passive House is a very well-insulated, a virtually air-tight building that is primarily heated by passive solar gain and by internal gain from people, electrical equipment, etc.

Energy losses in a Passive House are minimal. Any remaining heat demand is provided by a small and compact source. Avoidance of heat gain through shading and window orientation also helps to limit any cooling load, which is similarly minimized.

An energy recovery ventilator provides a constant, balanced fresh air supply, resulting with an impressive system that not only saves up to 90% of space heating costs, but also provides a unique indoor air quality.

The Passive House Planning Package (PHPP) is a useful software for planning a Passive House and serves as the basis of verification for the Passive House Standard.

Performance Characteristics:

• Airtight building shell ≤ 0.6 ACH @ 50 Pascal, measured by blower-door test

• Annual heating and cooling requirement ≤ 15 kWh/m2/year

• Primary Energy ≤ 120 kWh/m2/year
