This paper presents the measurement technique and results of 23 one-week measurements of air change rate in occupied dwellings. The measurements conducted show that the occupants exert a very considerable influence on the total air change rate. The air change rate for occupied dwellings is, on average, 3-4 times greater than the rate in sealed dwellings (with air-escape valves, doors, windows and ventilation system closed). The measurements also reveal a trend towards a higher air change rate in mechanically ventilated dwellings than in naturally ventilated dwellings.
