The Passive House is the world's leading standard in energy-efficient construction: The energy savings as compared to mandatory new building standards amounts to more than 80 per cent. Heating costs for a home are reduced to only ten to 25 Euros per month - high energy prices therefore hardly affect Passive House residents. The space heating demand in a Passive House is less than 15 kWh/(m²a) (with respect to the treated floor area).
The Passive House Institute (PHI) offers two certificates, which facilitate quality assurance of the design process:
All certificates offered by the PHI are based on published criteria and on characteristics and/or qualifications which can be verified objectively. The acquisition of a certificate from the PHI is voluntary and based on uniform contracts. The logos for the certificates are protected by trademark law.
