Intent 1:
To limit the probability of insufficient horizontal
reinforcement or that the horizontal reinforcement will not be adequately
encased and bonded to the concrete, which could lead to the cracking
of foundation walls due to temperature changes and shrinkage.
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.
