scope:

This standard applies to the design of new buildings and to the retrofit and renovation of existing buildings.

This standard applies to all types of buildings, building components, and materials.

This standard applies to all interior and exterior zones and building envelope cavities ^B-1.

This standard does not directly address thermal comfort or acceptable indoor air quality ^B-1.

This standard does not address the design of building components or envelopes to resist liquid water leakage from sources such as rainwater, ground water, flooding, or ice dams ^B-1.

Informative Note: All superscript notes such as B-1, B-2, and so forth refer to informative commentary on the standard that is contained in Informative Appendix B.

PURPOSE

The purpose of this standard is to specify performance-based design criteria for predicting, mitigating, or reducing moisture damage to the building envelope, materials, components, systems, and furnishings, depending on climate, construction type, and HVAC system operation. These criteria include the following:

a. Criteria for selecting analytic procedures

b. Criteria for inputs

c. Criteria for evaluation and use of outputs
