The ventilation rate of buildings is regulated in most European countries to ensure sufficient exchange of air to maintain a healthy indoor environment for people inside a building. Information on the actual levels of air exchange rate (AERs) is needed for estimation of the health benefits of adjusting ventilation rates, but unfortunately limited population based data are available on the measured air exchange rates in the European countries. To fill in this gap in knowledge we developed a Bayesian model to combine information from the existing measurements, national legislation and building codes, and to account for the climatological and economic trends when estimating the probability distributions of air exchange rates in 26 European countries. The results show that the mean air exchange rates vary from 0.6 (Ireland) to 1.1 (Cyprus) in European residences and the population weighted mean of the 26 European countries is 0.8.
