OH1 Indoor Conditions

To limit the probability of water ponding on floors.

This to limit the probability of:

- building elements coming into contact with water,
- the compromised thermal performance of components intended to provide resistance to heat transfer.

This is to limit the probability of:

- an inadequate control of 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 compromised integrity of elements protected by floors-on-ground.

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.
