Integrazione fotovoltaica nella sala Nervi Per la coerente e sistematica sperimentazione nella ricerca di un linguaggio architettonico capace di integrare le istanze delle tecnologie solari innovative in edifici ad alta qualità architettonica The very advanced “ bioclimatic concrete double roof” for the “ Sala Nervi” monumental architectonical building used for the Vatican Audience Hall of 8.000 seats designed by Pier Luigi Nervi in 1971, need a radical restoration intervention. The 4.800 concrete degraded roof tiles supported by different “umbrella steel structures” had to be substituted by new architectonical elementsfollowing the rigid rules of the Italian and international Restoration Chart, with some “ analogical aesthetical and technological characteristic”. The Vatican “Governatorato” and the scientific working team of the RomeUniversity coordinated by the Prof. Ing. Livio De Santoli had the courage to propose a complete photovoltaic roof design in order to assure the solar radiation protection and cover the energy need of the building and part of the Vatican connected structures. The design is supported by calculations and simulations try to produce the maximum level of architectural integration, defining the appropriate characteristic of the material, the size and the colours.
