Intent 1:
To limit the probability of precipitation or meltwater
ingress.
This is to limit the probability of
compromised thermal performance of components intended to resist heat
transfer, which could lead to:
- an inadequate control of temperatures in interior spaces,
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.
