	Requirements connected with the designing of low-energy and passive buildings impose an obligation to conduct airtightness tests during the building process and after the completion of building works. Proper building preparation is required before initiating an airtightness test. In case of commercial buildings with complicated HVAC systems, the proper preparation may appear to be very complicated and can unfavorable affect the tests results. On the example of tests conducted in the low-energy office buildings in Wrocław, the authors describe the problems met during airtightness tests.
