The clocks across China are counting down to the day in the evening of August 8th, the moment when Beijing will launch the games of the 29th Olympiad. In preparation for its moment in the centre of the world stage, the city has transformed itself from the downager of old to a dazzling young star decked out in a stunning display of architecture haute couture!

Beijing National Stadium aka The Bird Nest is a stadium finished for the Olympic Green will be an icon and new landmark for Beijing.

The stadium will host the opening and closing ceremonies, track and field as well as soccer events. It has a total capacity of 91,000 and 11,000 temporary seating will be removed after the Game, leaving a permanent capacity of 80,000.

Pritzker¹ Prize -winning architects – Herzog & de Meuron Architekten , a Swiss architecture firm founded and headquartered in Basel lead the design.

The structural form of the roof is decsribe as a "nest", an interwoven structural elements of the facade produce a single surface, upon which further elements are arranged in a chaotic manner to blurr the distinction between the primary and secondary structure. The roof is saddle in shaped, and the geomatry is developed from an ellips based. The steel roof, a single 330m long by 220m wide structure weighting 45,000 tonnes is clad with a series of ETFE (Ethylene Tetrafluoroethylene) panels on the structure to make the Nest one of the most ingeniously designed "green" buildings in the world. This layer reflects and absorbs sound to maintain the atmosphere in the stadium.

ETFE
ETFE, a transparent plastic related to Teflon is taking the place of glass and other plastics in many of the most innovatibe buildings being constructed today. It is also known as the material of the future. Compare to glass, it’s 1% the weight, transmit more light, is a better insulator, and cost far less to install. It’s also recycleable, self-cleaning and far tougher, with an estimated 50 years life span.

The nest was build using a polymer called ETFE.

This amazing Nest didn’t come cheaply but still, Beijingers love this building!
