Intent 1:
To exempt from the application of Sentence 5.7.1.1.(1) and Clause 5.7.1.1.(2)(a) buildings that
are specifically designed to accommodate the accumulation of water
at the building or the ingress of water.
Intent 2:
To limit the probability of damage to moisture-susceptible
materials, which could lead to:
- the inadequate control of 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 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.
