Los Angeles architects Emergent have won a competition to design a sports centre and arena for the 12th National Games of the People’s Republic of China, to be held in Liaoning in 2013. A roof with cellular windows and solar panels will cover the different areas with a form derived from natural crystal formations.
The Recreation Center and Swimming Arenas will be constructed out of reinforced concrete frame and slab construction for economy. Certain areas such as the pools and large gaming courts will feature column-less spaces and increased beam depth. Other spaces will relax back into a 7M x 7M economical grid spacing. This column grid will be carried all the way down through the parking garage in the basement.
The National Games Arena will be constructed out of reinforced concrete, concrete walls, and steel frame. The long span roof will be made from deep sculptured beams which will be stabilized by interior armatures. These beams will also contain the mechanical systems of the space. The opaque skin of the building will be aluminum panel, featuring thin-film solar technology in roof areas. The transparent areas will be made of ETFE bubbles, which are pressurized with air. This system is extremely lightweight compared to glazing, and therefore requires minimal structure to support it. In order to reduce solar gain in summer and heat-loss in winter, we propose to exchange patches of the transparent ETFE bubbles with translucent bubbles consisting of multiple layers of ETFE insulated with aero gel or other high-performance insulation.
