在炎热的火炉城市进行体育运动，建筑物需要优秀的降温防热系统，同时意味着巨大的能耗。从困境中思考，设置有巨大间隙的双层外皮形成的导风腔，利用前后温差造成的对流风，降温的同时，吹动隐藏在内的风力发电涡轮机组，主动环保。 In such hot city in southern China, to save energy of cooling down the huge building, we setup double layers facades with big gap distance.As wind tunnel, the air chamber guides the wind flowing into the wind-electric generator which hidden inside, at the same time shield the huge building from hot sunshine ,like an super big umbrella.
