The amount of outdoor air supply required in rooms were no one was smoking and only body odour was pesented was investigated using a climate chamer, under clean room conditions. Ten subjects were confined in the room and five panels outside of the room stated the odour level in the sampled air from theroom when compared to clean air. Experiments were performed in four steps of 5,10, 20 and 30 CMH per person. Room temperature was either 22-23 deg C or 32-33 deg C with a relative humidity of 50-60%. The higher temperature was used to study the influence of body odour in sweat. It was found that 1. Panels judged indoor air contamination level and odour level better than subjects and 2. There was a good correlation between carbon dioxide intensity and the level of odour sensation of the panel.
