Intent

Intent 1:

To limit the probability of an inability to control heat transfer through assemblies, which could lead to excessively low temperatures of interior surfaces, or within wall, ceiling or floor assemblies, which could lead to condensation.

This is to limit the probability of:

  • an inadequate control of the temperature of interior spaces or 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 assemblies acting as environmental 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.
