OH1 Indoor Conditions


(a) to (c) and (e) to (i)[F40,F50,F51,F52,F54,F63-OH1.1]


Intent 1:

To limit the probability that the inadequate design, construction or operation of heating or ventilating systems will lead to performance that is significantly below expectations, which could lead to:

  • an inability to maintain adequate indoor air temperature or to control relative humidity, which could lead to condensation, which could lead to the growth of mould and mildew, or
  • the inadequate control of airborne pollutants.

This is to limit the probability of negative effects on the air quality of indoor spaces, which could lead to harm to persons.
