9.27.3.1.(1)


Objective	OH1 Indoor Conditions
Attribution	[F61,F62-OH1.1,OH1.2,OH1.3]
Application	Application 1: Design and construction of the second plane of protection in cladding assemblies to which Subsection 9.27.3. applies [see Article 9.27.1.1. for application of Subsection 9.27.3.]. Exceptions: except as stated in Sentence 9.27.2.1.(1), which applies where it can be shown that precipitation ingress will not adversely affect occupant health or safety.

Intent	Intent 1: To limit the probability of: precipitation or meltwater ingress through the second plane of protection, and an inadequate dissipation to the exterior of precipitation or meltwater that does bypass the first plane of protection. This is to limit the probability of: compromised thermal performance of components intended to provide resistance to heat transfer, which could lead to an inadequate control of the temperature of interior spaces or relative humidity, the generation of pollutants from biological growth or from materials that become unstable on wetting, the ingress of water into interior spaces, or deterioration, which could lead to compromised integrity of exterior walls or elements protected by exterior walls. This is to limit the probability of: negative effects on the air quality of indoor spaces, the inadequate thermal comfort of persons, or contact with moisture. This is to limit the probability of harm to persons.
