Intent 1:
To limit the probability that frost-related soil
movement beneath the adjacent slabs-on-ground will be transmitted,
which could lead to excessive stresses, which could lead to the cracking
of slabs-on-ground supporting attached buildings, which could lead
to an inability to support vertical building loads.
This is to limit the probability of:
- pollutant ingress from the exterior, including soil
gas, combustion products from parking garages, or particulates,
- compromised thermal performance of components intended
to provide resistance to heat transfer,
- 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 water accumulation, or
- deterioration, which could lead to compromised integrity
of environmental separators or of elements protected by the 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.
