OH1 Indoor Conditions

Attribution

Intent

Intent 1:

To limit the probability of an inadequate substrate for the EIFS, which could lead to the EIFS having inadequate strength to resist impact or other lateral loads, which could lead to the excessive deformation or cracking of the EIFS, which could lead to:

  • precipitation or meltwater ingress, or
  • compromised thermal performance of components intended to provide resistance to heat transfer.

This is to limit the probability of:

  • an inadequate control of temperatures of interior spaces or relative humidity,
  • the generation of pollutants from biological growth or from materials that become unstable on wetting,
  • deterioration, which could lead to compromised integrity of exterior walls or elements protected by exterior walls, or
  • water accumulation in interior spaces.

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.
