AbstractThere is very little information available on air change rates in residential buildings that have some windows open to provide ventilation: the published data are usually for buildings that have the windows and doors closed. This paper reports the results of some studies that were conducted in Switzerland on small apartment buildings. The air change rates were measured using a tracer gas technique both with the windows closed and with some partially open. The air change rate increased by a factor of 4 when the windows on one facade were opened only a few centimeters. This shows how difficult it is to achieve adequate ventilation without increasing excessive heat loss when windows are used as the ventilators.
