Blower Door Test

The leakage of buildings and building components is a major source of energy losses, both heating energy during winter and cooling energy during summer. The air tightness of buildings is therefore a major influence for the decrease of energy consumption. I.F.I. may provide equipment for a standard blower door test or similar equipment adapted for special test demands.

ISO 9972 describes a test method to quantify the leakage of buildings or building components. The volume flow necessary to subject a room to a well defined pressure or suction will be measured. According to continuity equation this volume flow is equal to the leakage flow at the given pressure differential. It may be converted to specific parameters, e. g. air exchange rates.
