OH1 Indoor Conditions



Intent 1:

To limit the probability of an inability to inspect conditions or services in crawl spaces, which could lead to:

  • malfunctioning or inoperable building services, or
  • the ingress of water from the ground going undetected.

This is to limit the probability of:

  • an inadequate control of the temperature of interior spaces, relative humidity or the accumulation of moisture,
  • inadequate ventilation,
  • the production of hazardous by-products of combustion,
  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • deterioration, which could lead to compromised integrity of environmental separators or of elements protected by the separators.

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.
