The Passive House Institute (PHI) is an independent research institute directed by Dr. Wolfgang Feist.
The Institute is committed to careful scientific methodology in its work as well as to the principles of human dignity, perceiving one of its most important duties as being the preservation of decent living conditions both for our generation and all generations to come.
This drive has motivated PHI’s research in the field of energy efficient construction, for which Dr. Wolfgang Feist received the German Environmental Award in 2001 and the International Environmental Prize of the City of Gothenburg in 2003.
As a matter of principle, all research conducted by the Institute is transparent. PHI insists that all relevant results be published; this principle has been followed without exception.
Neither the Institute nor Dr. Wolfgang Feist hold shares in manufacturing or other companies, the only exception being limited shares in renewable energy power plants, and no contributions are made to the PHI by any third parties.
PHI does not favour the use of any particular products nor does it hold any patents or protected utility models for any such products, with the exception of the Passive House design Package, a design tool developed by the Institute.
The PHI logo, however, is a registered trademark and its use is restricted to products meeting the stringent requirements set by the Institute.
The Passive House Institute’s recommendations for certain measures, such as thermal protection, are solely based on the fact that these measures have proven to be highly effective in the past. Thermal protection, in particular, yields vast energy savings and improved levels of comfort. While thermal insulation, heat recovery and passive solar energy use are not an end in themselves, they serve a key purpose: they have proven to be the most effective means of reducing energy consumption as well as preserving and improving the building substance.
