Scope

This standard provides a calculation method for the thermal resistance and heat transfer coefficient of building components and units, but does not include doors, windows, and other components with glass, as well as components that transfer heat to the ground and components designed for air infiltration. This calculation method is based on the appropriate design thermal conductivity or design thermal resistance of the included materials and products. The standard applies to building components and units composed of thermally homogeneous layers (including air layers). This standard also provides an approximate calculation method for components with non-thermally homogeneous layers, but it is not applicable to insulation layers with metal thermal bridges.
