Intent 1:
To limit the probability of the incorrect calculation
of heat, air and moisture transfers, which could lead to the inadequate
performance or premature failure of components and assemblies of environmental
separators under expected environmental or structural loads, which
could lead to:
- air infiltration and exfiltration,
- condensation,
- precipitation ingress, or
- moisture ingress from the ground.
This is to limit the probability of:
- the inadequate control of temperatures of interior spaces,
relative humidity or water accumulation,
- the generation of pollutants from biological growth
or from materials that become unstable on wetting,
- deterioration, which could lead to further compromised
integrity of environmental separators, or
- pollutant ingress, including soil gas, combustion products
from parking garages, or particulates.
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.
