Abstract
Nowadays, the indirect method is the most common method for measuring airtightness of building components. This method is easy to setup in practice, but it can lead to substantial uncertainties. In laboratory, many authors use the direct component testing. However, it can be difficult to perform in-situ and, to our knowledge, no recent studies used it to quantify airtightness of building component in real buildings. This research aims at evaluating the practicability of the direct component testing. The method is applied to measure airtightness of installed windows in three different configurations. These tests highlight specific point of attention and possible limitations of the method. Direct component testing is then compared to indirect method. This paper concludes on the potential of the direct component testing method and mentions important limitations related to its setup. Further work should focus on repeatability studies for direct component testing and its practicability when measuring other building components than windows.
