OH1 Indoor Conditions



Intent 1:

To limit the probability of discontinuity and inadequate structural support and protection for water-resistant materials, which could lead to:

  • the ingress of moisture from the ground, including water that is under hydrostatic pressure, or
  • compromised thermal performance of components intended to provide resistance to heat transfer.

This is to limit the probability of:

  • an inadequate control of the temperature of interior spaces, relative humidity, or water ingress and accumulation, or
  • deterioration, which could lead to compromised integrity of floors-on-ground or of elements protected by the floors-on-ground.

This is to limit the probability of:

  • the inadequate thermal comfort of persons, and
  • contact with moisture.

This is to limit the probability of harm to persons.
