The National Construction Code (NCC) 2019 have recently introduced new legislation to help minimize the incidence of condensation within houses and apartments. Further measures and provisions are being considered in response to demands for healthier ventilation solutions.


What is the new ventilation standard?
Exhaust and Ducting provisions have become more specific, specially in regard to the discharging of the exhausted air.


3.8.7.3 FLOW RATE AND DISCHARGE OF EXHAUST SYSTEMS:

  1. An exhaust system installed in a kitchen, bathroom, sanitary compartment or laundry must have a minimum flow rate of
    1. 25 L/s for a bathroom or sanitary compartment; and
    2. 40 L/s for a kitchen or laundry.
  2. Exhaust from a bathroom, sanitary compartment, or laundry must be discharged
    1. directly or via a shaft or duct to outdoor air; or
    2. to a roof space that is ventilated in accordance with 3.8.7.4.

3.8.7.4 VENTILATION OF ROOF SPACES:

  1. Where an exhaust system covered by 3.8.7.3 discharges into a roof space, the roof space must be ventilated to outdoor air through evenly distributed openings.
  2. Openings required by (a) must have a total unobstructed area of 1/300 of the respective ceiling area if the roof pitch is more than 22Â °°, or 1/150 of the respective ceiling area if the roof pitch is not more than 22Â
  3. 30% of the total unobstructed are required by (b) must be located not more than 900mm below the ridge or highest point of the roof space, measured vertically, with the remaining required area provided by eave vents.
