Intent 1:
To limit the probability of:
- excessive heat transfer,
- excessive air infiltration or exfiltration,
- ingress of airborne pollutants from the exterior,
- infestation by insects or vermin, or
- precipitation ingress.
This is to limit the probability of:
- 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 doors, or
- the inadequate control of temperatures in interior spaces,
or drafts.
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.
