Intent 1:
To limit the probability of inadequate strength
and rigidity, which could lead to an inability to resist expected
lateral, gravity or wind-uplift loads, which could lead to excessive
movement, deformation or failure.
Where wood-frame
construction supports or is part of an environmental separator, this
is to limit the probability of the displacement or failure of required
environmental separation elements, which could lead to:
- condensation,
- precipitation ingress,
- moisture 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.
