Intent 1:
To exempt certain floors from the application of Sentence 9.13.2.1.(2), where:
- the ingress of moisture that is not under hydrostatic
pressure will not adversely affect health or safety owing to
- the high air leakage rate of the floors, which rapidly
removes moisture from the space, or
- the typically short duration of the presence of occupants,
or
- other actions are taken to limit the ingress of moisture.
