OH1 Indoor Conditions



Intent 1:

To limit the probability of an inadequate resistance to hydrostatic pressure, which could lead to the failure of floors-on-ground.

This to limit the probability of:

  • the ingress of moisture from the ground, or
  • the compromised thermal performance of components intended to provide resistance to heat transfer.

This is to limit the probability of:

  • an inadequate control of temperatures in 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 compromised integrity of floors-on-ground.

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.
