Intent 1:
To limit the probability of:
- an inadequate distribution of roof or floor loads transmitted
through framing elements, which could lead to overstressing of hollow
masonry units,
- an inadequate barrier, which could lead to termites
accessing structural wood elements, or
- the ingress of water into the cores of hollow masonry
units.
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.
