OH1 Indoor Conditions



Intent 1:

To limit the probability that windows, doors and skylights and their components will have insufficient resistance to heat transfer, which could lead to:

  • excessively low temperatures of interior surfaces, or
  • condensation, which could lead to
  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • deterioration, which could lead to compromised integrity of assemblies acting as environmental separators.

This is to limit the probability of:

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

This is to limit the probability of harm to persons.
