+ | In the PHPP worksheet U-Values of all building elements of the building envelope, or, in other words, all building elements through which heat is lost, are listed with their assemblies and respective thermal conductivity values. The calculation strictly follows EN standard 6946 (background information on the Passipedia pages ). | ||
