Air change and air leakage as a function of inflow. Luftwechsel und Luftleckage in Abhangigkeit der Einflussparameter.

In discussion of air infiltration, we must consider air leakage flow, air change, air changes per hour at 50Pa, the surface permeability coefficient, the component permeability coefficient and equivalent leakage area. Air change and air leakage data are given for multiple family houses, single family houses, offices, industrial buildings and single cell elements.
