[edit] Architecture

The Water Cube was initially designed by PTW Architects ^[2], CSCEC International Design and Arup with structural Engineers Arup conceiving the structure. The structure was built by CSCEC (China State Construction Engineering Corporation). Comprising a steel space frame, it is the largest ETFE clad structure in the world with over 100,000 m² of ETFE pillows that are only eight one-thousandths of an inch in total thickness,^[3] The ETFE cladding allows more light and heat penetration than traditional glass, resulting in a 30% decrease in energy costs^[3].

The outer wall is based on the Weaire-Phelan structure, a foam (structure formed by soap bubbles).^[4] The pattern is formed by taking a slice through the foam, and it was chosen in preference to the Kelvin foam because the more complex Weaire-Phelan structure results in more irregular, organic patterns than slices through the regular Kelvin foam.^[5]

The structure will have a capacity of 17,000^[3]during the games that will be reduced to 6,000 afterwards. It also has a total land surface of 65,000 square metres and will cover a total of 7.8 acres^[3].

[edit] Olympics

The Aquatics Center will host the Swimming, Diving and Synchronized Swimming events during the Olympics. The Water Polo was originally planned to be hosted in the venue but has been moved to the Ying Tung Natatorium.

[edit] Awards

“	The special award for the most accomplished work in the section Atmosphere is awarded to the Australian architecture firm PTW Architects, CSCEC + Design and Arup for the project National Swimming Center, Beijing Olympic Green, China. The project demonstrates in a stunning way, how the deliberate morphing of molecular science, architecture and phenomenology can create an airy and misty atmosphere for a personal experience of water leisure	”
