The prediction of building air tightness is often discussed. Although I have my doubts about most prediction method, some researchers show good compliance with measurements. I also have written ...
Building air tightness has been improved in several countries, but there is still a lot of potential for improvement. What are the solutions, what are the problems and the challenges. I hope to ...
An air tightness test will not only give information of the air tightness of the whole building but can also be used to identify air leakage in specific spots. Large air leakage on ...

The reason for this is twofold:
(1) When one uses only one test pressure, then the test results can be expressed with just one number, the “flow coefficient”. This is very simple and ...
