OH1 Indoor Conditions



Intent 1:

To limit the probability of inadequate resistance to condensation in high-humidity environments, which could lead to excessive condensation.

This is to limit the probability of:

  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • deterioration, which could lead to compromised integrity or performance of windows, doors and skylights or of building components protected by such components.

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.
