Scope: TC 1.12 is concerned with the interaction between the weather, the building envelope, its systems and its occupants which either lead to moisture accumulation or which prevent it. The committee performs cross-cutting research, and collects and distributes information to help the public and the professions avoid problems associated with excessive moisture. These efforts are coordinated with other technical committees, industries and professions which are responsible for individual systems, building components and public health and safety.

The committee (then known as TG 9.MMB) first met in Atlantic City, NJ, on January 11, 2002. Currently, we sponsor seminars at the Society's winter and summer meetings. In the near future, we hope to develop a research plan and draft a chapter for the ASHRAE handbook.
