Objective	OH1 Indoor Conditions
Attribution	[F61,F62-OH1.1,OH1.2,OH1.3]
Application	Application 1: Materials, components, assemblies, joints in materials, and junctions between components or assemblies that are: exposed to precipitation, and installed to provide protection against precipitation ingress in assemblies. This applies to building materials, components or assemblies and their interfaces described in Sentence 5.1.2.1.(1) that are installed in buildings to which Part 5 applies [see Sentence 1.3.3.2.(1) of Division A for application of Part 5]. Application 2: This also applies to cladding assemblies installed on buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9] where: the cladding assembly is not addressed in Section 9.27., or the cladding assembly does not comply with the prescriptive requirements of Section 9.27. Exceptions: except as stated in: Sentence 5.6.1.1.(2), which applies where a lack of control of precipitation ingress will not adversely affect health, safety, the intended use of the building or the operation of building services, and Sentence 5.6.2.1.(2), which applies where a lack of sealing and drainage will not adversely affect health, safety, the intended use of the building or the operation of building services.

Intent	Intent 1: To limit the probability of: the inadequate control of precipitation ingress, or the inadequate provision for dissipation of precipitation that does enter an assembly, which could lead to the ingress or accumulation of water. This is to limit the probability of: the inadequate control of 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 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.
