OH1 Indoor Conditions




Intent 1:

To limit the probability that the inadequate design, construction or operation of heating, ventilating or air-conditioning systems will lead to performance that is significantly below expectations, which could lead to the inadequate control of:

  • relative humidity or indoor air temperatures,
  • surface temperatures,
  • air velocity, or
  • condensation.

This is to limit the probability of:

  • the inadequate thermal comfort of persons, and
  • contact with moisture.

This is to limit the probability of harm to persons.
