Intent 1:
To limit the probability of an inability to direct
water to the exterior, which could lead to precipitation ingress,
which could lead to the failure of required environmental separation
elements.
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 the temperature of interior spaces 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.
