What is a Passive House?

Passive House buildings are buildings using very high energy efficient components such as a highly insulated building shell, heat recovering of the exhausting air as well as the use of external gains of solar radiation in the winter season. Passive House buildings need 80 % less energy for heating and cooling compared to conventional standards of new buildings and 90 % less energy than the existing building stock. The requirements to fulfil the Passive House standard are:

  • less than 15 kWh/(m²a) according to PHPP for heating or
  • a maximum value of 10 W/m² for the heat load allowing fresh air to carry the heat load.

Further information about the Passive House concept is available at the websites www.passiv.de and www.igpassivhaus.at.

If you want to test a Passive House and live there for some days, you can do this at “Sonnenplatz Großschönau” www.probewohnen.at.
