OH1 Indoor Conditions



Intent 1:

To limit the probability of the incorrect calculation of wind loads, which could lead to the inadequate performance or premature failure of components and assemblies of environmental separators under expected wind loads, which could lead to:

  • air infiltration and exfiltration,
  • condensation,
  • precipitation ingress, or
  • moisture ingress from the ground.

This is to limit the probability of:

  • the inadequate control of temperatures of interior spaces, relative humidity or water accumulation,
  • the generation of pollutants from biological growth or from materials that become unstable on wetting,
  • deterioration, which could lead to further compromised integrity of environmental separators, or
  • pollutant ingress, including soil gas, combustion products from parking garages, and particulates.

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.
