Intent 1:
To limit the probability of:
- silting-up of the sump pit,
- excessive moisture transfer from the sump pit into interior
spaces, or
- the ingress of soil gases.
This is to limit the probability of:
- an inadequate control of the temperature of interior
spaces, relative humidity, or water accumulation,
- compromised thermal performance of components intended
to provide resistance to heat transfer,
- the generation of pollutants from biological growth
or from materials that become unstable on wetting, or
- deterioration, which could lead to compromised integrity
of elements protected by the 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.
