5.2.2.1.(1)


Objective	OH1 Indoor Conditions
Attribution	[F20,F21,F22-OH1.1,OH1.2,OH1.3]
Application	Application 1: Determination of structural loads for the design of materials, components and assemblies that are subject to structural loads, such as those identified in Part 4 (see Clause 5.1.4.1.(3)(a) and Sentence 5.2.2.1.(2)). This applies to building materials, components, 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].

Intent	Intent 1: To limit the probability that incorrect loads will be used in the structural design of environmental separators, which could lead to an inadequate resistance to expected structural loads on required environmental separation elements, which could lead to damage and deterioration. This is to limit the probability of the inadequate performance or premature failure of required environmental separation elements, which could lead to: air infiltration and exfiltration, condensation, precipitation ingress, moisture ingress from the ground, or pollutant ingress, including soil gas, combustion products from parking garages, or particulates. This is to limit the probability of: the 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.
