Ventilation requirements for the control of body odour in spaces occupied by women

40 female and 39 male judges have each evaluated the intensity and acceptance of body odour 29 times on entering an experimental auditorium occupied by 105 women. During the experiment, which lasted three hours and 50 minutes, the ventilation rate was varied while the air temperature was kept constant around 20-21 deg C. Carbon dioxide was measured continuously. No substantial difference was found in the ventilation rates required in spaces occupied by women and men. A ventilation rate around 8 l/s per person is required to satisfy 80% of people entering a space.
