Intent 1:
To limit the probability that inappropriate procedures
will be used for the structural design of environmental separators,
which could lead to an inadequate resistance to expected structural
loads on required environmental separation elements, which could lead
to:
- vibration and deflection,
- damage and deterioration, or
- the inadequate control of:
- the total heat loss or gain due to air mass transfer
or conduction,
- air infiltration and exfiltration,
- airborne vapour transfer from the interior above ground
and from the exterior below ground,
- precipitation ingress due to air pressure differences,
or
- condensation.
This is to limit the probability of:
- the inadequate control of temperatures of interior spaces,
drafts, relative humidity, or water accumulation,
- pollutant ingress, including soil gas, combustion products
from parking garages, and particulates,
- 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.
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.
