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.
