Project Systems
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 elements
following the rigid rules of the Italian and
international Restoration Chart, with some “
analogical
aesthetical
and
technological
characteristic”.
Actual state
The Vatican “Governatorato” and the scientific
working team of the Rome University 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.
