OH1 Indoor Conditions



Intent 1:

To limit the probability of discontinuity in the ground cover, which could lead to:

  • the ingress of moisture that is not under hydrostatic pressure from the ground, or
  • the infiltration of soil gas.

This is to limit the probability of:

  • an inadequate control of relative humidity,
  • 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 or of elements protected by the 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.
