Intent 1:
To limit the probability of the ingress of surface
water through cracks or other anomalies in foundation walls, or of
overloading perimeter drain tiles.
This is to
limit the probability of:
- condensation,
- precipitation 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 the temperature of interior
spaces or water accumulation,
- the generation of pollutants from biological growth
or from materials that become unstable on wetting, or
- compromised integrity of environmental separators, 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.
