The rooftop has changed the shape respect the old version; in fact, it is a flat roof, which was also used in the typical southern architecture to help the heat flows to leave the building in summer. On the top there are photovoltaic panels and solar panels all over the area to optimize the electric and heat energy production.
The internal space is design to maximize the solar entering so to use less electric light as possible (preferring the natural one). It is equipped with LED on the perimeter of the ceiling to diffuse the light on the white walls. The internal space heated and cooled has a surface of 378.81m2 and a volume of 1467.91m3.
