LoginIndoor environment quality in buildings strongly depends on the proper ventilation. Still a large amount of single- and multifamily buildings are equipped with the natural ventilation system.
When the air exchange in the building is estimated, the main uncertainty concerns the air tightness of the given object. This parameter is used as the input data when the ventilation air flows in building are simulated, and therefore a reliable determination of the air tightness is essential.
The method of determining of the air tightness consists of the measurement of the air flows through the investigated flat or house for the given pressure difference. The procedure and techniques are well- known and the measurement is realized by so-called blower door.
The paper presents the course and results of experiments performed in several flats in different multifamily buildings as well as in the single-family house.
