OH1 Indoor Conditions



Intent 1:

To limit the probability that an inability to drain or clean out the ducts will lead to the accumulation of moisture, which could lead to:

  • the inadequate delivery of warm air or the return of cold air, which could lead to an inability to maintain adequate indoor air temperatures,
  • inadequate ventilation, which could lead to the inadequate control of:
    • relative humidity, which could lead to condensation, which could lead to mould and mildew growth, or
    • airborne pollutants, or
  • the entry of water into living space.

This is to limit the probability of:

  • negative effects on the air quality of indoor spaces,
  • the inadequate thermal comfort of persons, and
  • contact with moisture.

This is to limit the probability of harm to persons.
