An exclusive 6,000 m² glass roof made of building-integrated photovoltaics with an output of ~1.2 MWp replaces the original glass roof. Renzo Piano chose semi-transparent glass-glass modules from Sunovation, which were individually manufactured according to his designs. With over 300 different geometries, the glass-glass modules were precisely adapted to the existing historical building structure. The design of the glass-glass modules played a fundamental role alongside the technical specifications. In order to perfectly integrate them into his design of a light-flooded building, Renzo Piano opted for a degree of transparency of ~20% as well as an individual design of the PV cells. Their appearance was refined in shape and color by imprints in shades of gray and white on different glass layers. The realization of this exclusive design was made possible by the special production process of the module manufacturer Sunovation, which offers the greatest variety of individualization options in the field of customized BIPV modules.
