The main stadium for next year's Beijing Olympic Games, the $400 million "bird's nest", will open to the public for the first time in April 2008.
The structure itself is composed of a grid-like formation that serves as both structure and facade, integrating the stairs, walls, and roof into one cohesive system. Instead of form being dictated by function, Herzog and DeMeuron’s design effectively removes the distinction, making function and form one in the same.
Such a large-scale and highly-trafficked building raises questions of waste, efficiency, and cost, but the “Bird’s Nest” seems to pose innovative, green solutions to a variety of potential building issues. Its green features include a rainwater collection system, a translucent roof that provides essential sunlight for the grass below, and a natural, passive ventilation system.
Perhaps the most unique feature of the structure is its “cushion” system which strategically fills the spaces within the building’s facade to regulate wind, weather, and sunlight. On the rooftop, the inflatable cushions fill gaps to weather- and waterproof the stadium. “Just as birds stuff the spaces between the woven twigs of their nests with a soft filler, the spaces in the structure of the stadium will be filled with inflated cushions.” Coincidentally, the cushions will be made from ETFE, the same material used to create the translucency of the “bubble building” across the Olympic park.
Sculptural rather than an architectural sensory overload like many a contemporary stadium, “it meets all the functional and technical requirements of an Olympic National Stadium, but without communicating the insistent sameness of technocratic architecture dominated by large spans and digital screens.”
