The objective of the requirement is to provide a means of achieving background ventilation which is adequately secure and does not significantly affect comfort in habitable rooms and kitchens. For background ventilation an opening (or openings) having a total area not less than 4000 sq mm is required.

Where combustion air for open flue appliances needs to be provided British Standard BS5440 (Part 2) requires 645 sq mm opening for every 5000 btu/hr input in excess of 25000 bt/hr.
