Whole building ventilation

Approved document F, Ventilation, suggests that ‘whole building ventilation’, or ‘general ventilation is:

‘…nominally continuous ventilation of rooms or spaces at a relatively low rate to dilute and remove pollutants and water vapour not removed by the operation of extract ventilation, purge ventilation or infiltration, as well as supplying outdoor air into the building. For an individual dwelling this is referred to as ‘whole dwelling ventilation’.’


Whole building ventilation might be provided by background ventilators, as illustrated below.
