What is Passivhaus?
Passivhaus is a set of scientifically based construction measures for ultra-high building performance. Dr. Bo Adamson & Dr. Wolfgang Feist refined previous findings for building efficiency and created their own performance metrics in 1996. They are recognised as the founders of the Passivhaus concept. The 5 key criteria of a Passivhaus are:
The purpose for implementing these principles is to create a building that can achieve thermal comfort using only the heating and cooling of the fresh air required to maintain healthy indoor air quality.
Definition: Thermal Comfort (Passivhaus)
