Area of fresh air vent in habitable rooms• At least 60 cm2 for up to 25 m2
floor area with natural ventilation
• At least 30 cm2 for up to 25 m2 floor area for mechanical extraction.
In room larger than 25 m2, the requirement is deemed to have been met if the opening area:
In the case of natural ventilation is augmented by 2,4 cm2 pr m2 floor area in excess of 25 m2
Area of fresh air vent in habitable rooms
Example :
Living room 40 cm2
40 x 2,4 = 96 cm2 opening
Or
60 cm2 + (40-25) x 2,4 cm2
= 96 cm2 opening
