Intent 1:
To limit the probability of discontinuity in the
ground cover, which could lead to:
- the ingress of moisture that is not under hydrostatic
pressure from the ground, or
- the ingress of moisture that is not under hydrostatic
pressure from the ground, which could lead to compromised thermal
performance of components intended to provide resistance to heat transfer.
This is to limit the probability of:
- an inadequate control of the temperature of interior
spaces or relative humidity,
- 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 or of elements protected by the separators.
This is to limit the probability of:
- negative effects on the air quality of indoor spaces,
and
- the inadequate thermal comfort of persons.
This is to limit the probability of harm to persons.
