scope:

This pre-standard specifies the application of solar energy systems (or complete building elements with photovoltaic (PV) or thermal solar systems) as an integrated or stand-alone element of the external building envelope. It concerns roofs as well as facades of houses, residential buildings and commercial and industrial buildings. Where relevant, the provisions described in this standard are to be applied to a complete solar energy system that is installed (in accordance with the guidelines of the supplier) in its intended architectural context with all construction details included. After mounting of the solar energy system the regular functions and properties of the building envelope should remain unaltered, respectively adequate. One may think of the constructive safety (increased load due to the solar energy system), water drainage, the presence of thermal bridges, the pressure resistance and negotiability of the underlying insulation material. Glazed PV elements that are finished as normal glass elements fall outside the scope of this prestandard. As far as the mounting of such elements in wooden, plastic and metal frames is concerned the requirements for normal glass elements are applicable.
