OH1 Indoor Conditions



Intent 1:

To limit the probability of insufficient reinforcement or that reinforcement across a cold joint will not be adequately bonded to the concrete, which could lead to tension loads not being transferred to each side of the joint, which could lead to concrete cracking or the displacement of foundation walls.

Where elements support or are part of an environmental separator, this is to limit the probability of:

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

This is to limit the probability of:

  • an 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, or
  • compromised integrity of elements supported by foundations, which could lead to the deterioration of building elements.

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.
