The Tale of the Breathing Building
It is a myth that buildings need to have cracks and joints to “breathe naturally.” Such air change occursin an uncontrolled manner. Too much or too little outdoor air will enter the building. Even worse, pollutants and dust from the insulation mix with the indoor air. A building should consequently be ventilated by frequently opening the windows or via a ventilation system.
The BlowerDoor test allows you to test the air tightness of buildings. It can protect against severe structural damage caused by warm and humid indoor air penetrating the building construction through joints. In addition, the indoor comfort level rises through the elimination of draughts or cold-air pools. When rehabilitating existing buildings, an air barrier planned according to the recognized standards often achieves current low-energy or even passive-house standards.
