Air quality in buildings during smoking and non smoking occupancy.

Looks at ventilation requirements for both odour and physical acceptability and pays particular attention to the differences between smoking and non smoking occupancy in an environmental chamber. Results imply that under non smoking conditions and with moderate humidity, between 5 and 10 cfm of fresh air per occupant should satisfy 75% of visitors, but that under smoking conditions, many times as much fresh air is needed for both odour acceptability and compliance with customary criteria values for smoke.
