Intent 1:
To limit the probability that there will be insufficient
reinforcement to transfer the loads around openings in the walls,
which could lead to an inability to resist transverse or vertical
loads, which could lead to concrete cracking or the displacement of
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, 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
- deterioration, which could lead to further compromised
integrity of 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.
