Probabilistic analysis of air infiltration in low-rise buildings

The probabilistic model (PROMO) applied to the problem of air infiltration in low-rise buildings is presented. The model allows estimation of the effect of variations of climatic conditions on air exchange in a building. Probabilistic output in the form of probability density function of air change rate forms a ground for reliability analysis of adequate ventilation. PROMO model is applied to analyse the air exchange caused by air infiltration in a house situated near Gothenburg. The model is validated on the basis of the results of measurements obtained for that house.
