          ASHRAE Technical Committee 4.4

          Building Materials and Building Envelope Performance



Welcome to the Web Site for ASHRAE Technical Committee 4.4. If you would like to become involved with the committee, please attend one of our meetings that take place during the ASHRAE Annual and Summer meetings, or contact the Chair of the Committee. New members are always welcome!

TC 4.4 is concerned with the requirements and overall performance of the building envelope as it relates to: 1) heat, air and moisture related properties of building materials 2) fundamental heat, air and moisture transport processes of assemblies; 3) interactions with interior conditions and HVAC systems. In addition, TC 4.4 is concerned with the properties of materials used in mechanical systems to control heat and moisture flows.
