DFA’s submission for the 2012 Olympic Pavilion in Trafalgar Square incorporates interactive multi-media design, as well as basic concessions for event tickets, information, and food. The structure is fully self sustaining, and consistent with competition guidelines that the pavilion have a ‘net-zero’ energy footprint. The entire structure is wrapped in a rubber skin, and electricity is generated as visitors circulate over its lead zirconate titanium (PZT) surfaces. The ‘green’ roof of the pavilion collects rainwater which contributes to a grey water system, and additional surfaces support a photovoltaic membrane for added power generation. Large screens on the exterior of the pavilion face the steps of the National Gallery, and an outdoor amphitheater is created where onlookers can watch live events, as well as information being broadcast regarding the Games.
