Defines the characteristics related to dynamic thermal behaviour of complete building components and gives methods for their calculation. Covers the information on building materials required for its use. Since the characteristics depend on the way materials are combined to form building components, the standard does not apply to building materials or to unfinished building components. A simplified calculation method is provided for plane components consisting of layers of homogeneous or substantially homogeneous building material.
