Passive House Institute

The international Passive House standard was launched in 1996 by the Passive House Institute (PHI), following the construction and monitoring of the first Passive House pilot project in 1991. It delivers high performance buildings in all climates of the world, taking into account the respective context.
Thanks to an approach that focuses on the envelope and efficient mechanical systems, Passive House buildings can consume up to 90% less heating and up to 80% less cooling energy than typical existing buildings, depending on climate. At the same time, they provide healthy, high quality living and working conditions (comfortable temperatures all year round, no drafts or mold, good indoor air quality). With very low operating costs and high temperature stability, these buildings also provide resilience against rising energy prices and changing climate conditions.
