N2 - Uncontrolled air leakages through the building shell increases energy consumption and deteriorates the indoor air quality by allowing the outdoor airborne contaminants to enter indoors. The accurate determination of air leakages is difficult, especially in large buildings. To quantify the air leakages within mechanically ventilated buildings a new method has been developed. It consists of a computational model and measured outdoor air, filtered supply air and exhaust air particle concentrations. Based on the measured concentrations, the leakage air flow can be achieved by fitting the experimentally obtained air concentrations with theoretically calculated values. The method was tested at a field measurement site during a four month measurement period. The results show that leakage flows could be reliably determined by the method described and that leakage flows are clearly dependent on weather conditions.
