6th International BUILDAIR Symposium on Building and Ductwork Airtightness, 6 May 2011, Berlin, Germany

This presentation will give an introduction to the approach of determining the required number of testing fans when conducting air tightness measurements of large buildings. From experience in testing practice and recording measurement results, we know that large buildings regularly achieve significantly better test results than required by German regulations. To share our experience, we will present these good test results to start a discussion as to which limits of air tightness in large buildings can be considered adequate.
