Ventilation Rate - an overview ScienceDirect Topics

Ventilation requirements in housing can be satisfied in most cases with 25 cu m/h of fresh air per person or 1.26 cu m/h per square metre of floor area. These are equivalent to about 0.5 ac/h for a 100 sq m house and can be met by casual infiltration through cracks without opening windows in winter.
