Olympic Stadium, BeijingHerzog & de Meuron
Under construction, to be completed in 2008
Sports stadiums have long followed the enduring design of one of the original wonders of the world, Rome's Coliseum. Herzog & de Meuron's National Stadium in Beijing is an attempt to rethink the classic sports-arena layout for more ecologically correct times.
The Swiss architects (of Tate Modern fame) wanted to provide natural ventilation for the 91,000-seat structure -- perhaps the largest "eco-friendly" sports stadium designed to date. To achieve this, they set out to create a building that could function without a strictly enclosed shell, yet also provide constant shelter for the audience and athletes alike.
To solve these design problems, they looked to nature for inspiration. The stadium's outer grid resembles a bird's nest constructed of delicately placed branches and twigs. Each discrete space within the facility, from restrooms to restaurants, is constructed as an independent unit within the outer lattice -- making it possible to encase the entire complex with an open grid that allows for natural air circulation. The architects also incorporated a layer of translucent membrane to fill any gaps in the lacy exterior.
