OH1 Indoor Conditions



Intent 1:

To limit the probability of wind-washing or short-circuiting, which could lead to the inadequate control of heat transfer through environmental separators under expected environmental loads, which could lead to:

  • excessive heat loss or gain, or
  • condensation.

This is to limit the probability of:

  • the inadequate control of temperatures of interior spaces,
  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • deterioration, which could lead to compromised integrity of 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.
