History of Passive Design

The Passivhaus standard was created at the beginning of the 1990's by Professors Bo Adamson and Wolfgang Feist; with residents moving into the first prototype Passivhaus building in 1991.

In 1996, Dr. Wolfgang Feist founded the Passivhaus Institut; a research institute to further develop the Passivhaus standard and to promote its adoption internationally. 

How does Passive Design work?

Passive Design works on a specific set of principles: 

1. Solar Gain 

2. Thermal Mass

3. Super Insulation 

4. Airtightness
