OH1 Indoor Conditions



Intent 1:

To limit the probability that the performance of form material for use in flat insulating concrete form foundation walls will fall significantly below expectations, which could lead to:

  • the dislodgement or failure of form material,
  • the excessive sagging and misalignment or opening of joints,
  • excessively low temperatures of interior surfaces or within assemblies, or
  • an inadequate resistance to air and moisture transfer.

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.
