Ventilation of buildings : fresh air requirements.

Discusses reasons for ventilating buildings and theories of ventilation. Summarises American and British recommendations for fresh air supplies. Concludes that the necessary volume of fresh air per person per minute varies considerably with thecircumstances but these volumes can be determined from the fundamental considerations. In general the recommended figure is to be preferred to the minimum figure as given in engineering reference books, and the quantity of fresh air supplied should never fall below 10 cubic feet per person per minute in ordinary normal buildings.NOTES replaces Technical Data note 19, HMSO. 1970.
