Scope
Technical Committee 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.

Scope
Technical Committee 4.5 is concerned with the identification and evaluation of all physical properties of (1) glasses and other glazing materials, (2) shading and shielding materials and devices, and (3) control devices and strategies which influence the radiant, conduction, and convection transfer of both heat and light through fenestration systems. It is also concerned with the development of procedures for calculating and measuring solar heat gain, daylight admission, and heat transfer through fenestration systems.
