Airtightness measurements in Passive House buildings are to be carried out uniformly worldwide according to ISO 9972, method 1. The deviations (these are not of a fundamental nature), clarifications and additions to the standard in relation to Passive Houses are described here. \\ | Airtightness measurements in Passive House buildings are to be carried out uniformly worldwide according to ISO 9972, method 1.
