This paper reports on measurements of air change rate in dwellings during occupancy. The occupants were shown to exert a considerable influence on the total air change. The air change rate for occupied dwellings is, on average, 3-4 times greater than the air change rate in sealed dwellings (with air escape valves, doors, windows, and ventilation system closed). The measurements also reveal a tendency for higher air change rates in mechanically ventilated dwellings than in naturally ventilated dwellings.
