Application | Application 1: Resistance to deterioration and structural and environmental
loads, as well as the effects of those loads, of building materials,
components, assemblies and their interfaces described in Sentence 5.1.2.1.(1) that
are installed in buildings to which Part 5 applies
[see Sentence 1.3.3.2.(1) of Division A for application of Part 5].
Application 2: This also applies to cladding assemblies installed
on buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9] where:
Application 3: This also applies to the position of low air and vapour
permeance materials within the building assembly
relative to the position of materials providing thermal resistance in the
assemblies of buildings to which Part 9 applies
[see Sentence 1.3.3.3.(1) of Division A for application of Part 9], where
the building assembly:
Application 4: This also applies to the design of vapour
barriers in buildings to which Part 9 applies
[see Sentence 1.3.3.3.(1) of Division A for application of Part 9], where
the building assembly is more susceptible to condensation
[see Sentences 9.25.4.2.(2) and (3) for combinations of interior and exterior
environmental conditions that create a higher risk for condensation].

Intent | Intent 1: To limit the probability of an inadequate resistance to
expected environmental loads and deterioration, which could lead to:
This is to limit the probability of:
This is to limit the probability of structural failure, which could
lead to harm to persons.
