Intent 1:

To limit the probability that the performance of heating or air-conditioning systems, with respect to maintaining indoor air temperatures and relative humidity, will fall significantly below expectations.

This is to limit the probability of the inadequate control of temperatures and relative humidity, which could lead to condensation, which could lead to:

  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • the deterioration of building elements.

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.
