How do I ventilate the basement?

Ventilation

Basements used for habitable or workplace use should have adequate natural ventilation. Rapid ventilation, through openings of not less than 1/20th of the floor area, with secure controllable background ventilation, should be provided.

An appropriately designed mechanical ventilation system may be used as an alternative for workplace uses.

Note: Ventilation should be maintained to any adjacent timber ground floor, for the prevention of condensation and any consequent risk of timber decay.
