ObjectiveOH1 Indoor Conditions
Attribution
[F22-OH1.1,OH1.2,OH1.3] Applies to elements that support or are part of an environmental separator.
Application
Application 1: 
Anchorage of exterior columns and posts, or of supported joists or beams, in wood-frame constructions to which Section 9.23. applies [see Sentence 9.23.1.1.(1) for application of Section 9.23.], where:
  • the columns or posts support balconies, decks, verandas or other exterior platforms, and
  • the distance from finished ground to the underside of the joists is not more than 600 mm.
Exceptions: 
except as stated in Sentence 9.23.6.2.(3), which applies to columns or posts supporting small, single storey balconies, decks, verandas or other exterior platforms that do not support a roof and where movement will not adversely affect the structure to which the platform is attached.

Intent
Intent 1: 
To limit the probability of an inability to resist expected wind and lateral loads, which could lead to platforms lifting or sliding off foundations.
For construction that supports environmental separators, this is to limit the probability of the displacement or failure of required environmental separation elements, which could lead to:
  • condensation,
  • precipitation ingress,
  • excessive heat transfer,
  • pollutant ingress, or
  • compromised thermal performance of components intended to resist heat transfer.
This is to limit the probability of:
  • an inadequate control of temperatures of interior spaces, drafts, relative humidity or water accumulation,
  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • deterioration, which could lead to further compromised integrity of environmental separators.
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.
