Intent

Intent 1:

To limit the probability that insufficient heat will reach the soil around foundations, which could lead to the freezing of soil, which could lead to frost-related soil movement, which could lead to cracking of footings, slabs-on-ground or building envelope assemblies supported by footings or slabs-on-ground.

This is to limit the probability of:

  • condensation,
  • precipitation ingress, or
  • the ingress of moisture from the ground.

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 or protected by environmental separators.

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.
