OH1 Indoor Conditions

To limit the probability of:

- excessive moisture loading on foundation walls and basement floors, or
- the flooding of interior spaces.

This is to limit the probability of:

- the ingress of moisture from the ground, or
- compromised thermal performance of components intended to provide resistance to heat transfer.

This is to limit the probability of:

- an inadequate control of the temperature of interior spaces, relative humidity, or water ingress and accumulation,
- 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.
