The building has many sustainable features, but the most prominent feature is a series of photovoltaic panels protruding from its steel roof. During daylight hours, they will tilt to follow the sun's course across the sky. Other pedagogic green features include pools to capture rain water for use in the plumbing system, as well as pools that naturally filter water from the bay. Pumps will harvest sea water, moreover, to cool interior rooms and galleries- all features that could earn LEED certification from the Green Building Council Brazil. The interactive exhibits will contextualize sustainability within Brazil's landscape.
Another interesting proposal by RAFAA, is the Solar City Tower. The tower will consist of an artificial water fall in Rio's harbor, powered by photovoltaic panel that would power pumps to carry sea water 344 feet above the bay. It will then send water tumbling down past electricity- generating turbines that would help power athlete housing during the 2016 Olympics. The energy generated by the sun can be used to power the city during the day, and excess energy from the turbines can be used for evening power.
