What is the recommended ventilation rate for offices?
For offices where there is no smoking, CIBSE Guides A: "Environmental Design" (2006) recommends an outdoor air supply rate of 10 litres/second per person. Spaces in which smoking is permitted should be regarded as 'smoking rooms' and an outdoor air supply rate of 45 litres/s per person is suggested for such rooms. However, it should be noted that this recommendation aims only to reduce discomfort and does not ensure health protection.
