OH1 Indoor Conditions




Intent 1:

To limit the probability that the performance of insulating glass will fall significantly below expectations, which could lead to the inadequate control of heat transfer, which could lead to:

  • the inadequate control of temperatures in interior spaces, or
  • condensation.

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 windows or adjacent exterior wall assemblies.

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.
