Measurement of the airtightness of buildings

The Energy Saving Ordinance stipulates, among other things, that the heat-transferring enclosing surface must be designed to be permanently airtight in accordance with the state of the art and that a minimum air exchange rate must be ensured. The Center for Energy, Water and Environmental Technology, or ZEWU for short, carries out measurements of the airtightness of buildings.
