Air tightness test of rooms

The article introduce a joint project of Pécs University and Osijek University. The aim of the project is to obtain information on the air tightness and on the natural air change rate of a set of buildings and houses in the Hungarian- Croatian border region. Another scientific aim is to find correlation between air change rates at +50 Pa and -50 Pa inside-outside pressure difference, 4 Pa pressure difference and air change measured with tracer gas concentration decay method. Tracer gases are SF6 and CO2.
