Intent 1:
To limit the probability of insufficient support
for flat insulating concrete form foundation walls, which could lead
to an inability to support lateral earth loads, which could lead to
movement of the walls, which could lead to concrete cracking or displacement
of the walls.
Where elements support or are part
of an environmental separator, this is to limit the probability of:
- condensation,
- rainwater 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 temperatures of interior spaces,
relative humidity, or water accumulation,
- the generation of pollutants from biological growth
or from materials that become unstable on wetting, or
- compromised integrity of elements supported by foundations,
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.
