Intent 1:
To limit the probability that expected loads, other
than those listed in Sentences 5.2.2.1.(1) and (2), will not
be taken into account in 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 damage and deterioration.
This is to limit
the probability of the inadequate performance or premature failure
of required environmental separation elements, which could lead to:
- air infiltration and exfiltration,
- condensation,
- precipitation ingress,
- moisture ingress from the ground, or
- pollutant ingress, including soil gas, combustion products
from parking garages, or particulates.
This is to limit the probability of:
- the inadequate control of temperatures of interior spaces,
drafts, 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.
