Parliament Building of Malta by Renzo Piano

Renzo Piano's breathtaking Parliament Building was completed in 2014. Its design includes two massive volumes of stone that look suspended in air, but are supported by stilts. The blocks have been machine-cut to lighten their appearance while reducing solar radiation and letting in daylight. Covering the rooftop are 600 sq metres of photovoltaic panels, which generate most of the energy required to heat the building in winter and cool it in summer.
