Intent 1:
To limit the probability of:
- an inability to resist expected wind loads, and
- where the superstructure is required to provide lateral
support for the foundation, an inability to resist expected lateral
earth pressure loads, which could lead to:
- cracking or differential movement of the foundation,
or
- compromised structural integrity of the foundation.
For environmental separators or construction that supports
environmental separators, this is to limit the probability of the
displacement or failure of required environmental separation elements,
which could lead to:
- condensation,
- precipitation ingress,
- excessive heat transfer,
- pollutant ingress, or
- compromised thermal performance of components intended
to resist heat transfer.
This is to limit the probability of:
- inadequate control of temperatures of interior spaces,
drafts, 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.
