Home Energy & Safety Eco Passive House

Passive Houses and House Designs

The conventional passive house has been taken on by Baufritz for further development. What we now call the complete-solution passive house has an airtight construction and offers perfect heat retention. - We are boasting a 1.5-litre house, on account of the high degree of airtightness. Creating a healthy living environment is then just a matter of building free of harmful substances. That is why we use no harmful artificial materials, whose emissions would spread and settle in the ambient air of a  passive house. - We build naturally healthy passive houses. A big and decisive difference for your future quality of life!


The passive house lives from passive heat. The way it operates is simple: The special design enables passive heating of the house, for example, by sunlight and residual heat from technical equipment and even from the people. The entire building envelope is designed to prevent heat loss. Thanks to intelligent ventilation you can simply breathe freely in your Baufritz house.
The Baufritz passive house design meets all the criteria and requirements of the Passive House Institute and even exceeds them:
  • Heating requirements of ≤ 15 kWh per m²
    (1.5 litres of oil or 3 kg of pellets per m² living space)
  • Primary energy requirement ≤ 120 kWh per sqm (for heating, ventilation, hot water, auxiliary and household electricity)
  • Maximum air tightness of the building envelope (n 50 ≤ 0.6 h-1)
