The water Cube - Beijing Olympics National Swimming Centre
Jun 22nd, 2008 by admin
One of the obvious advantages of taking over the organizations of any major world event is architects competing to decorate the host city or nation with new buildings. Such is the case with Beijing of course, preparing for this year’s Olympic Games. The city has been turned into a giant open air museum of modern architecture, with architects from all over the world competing to make the most memorable and beautiful buildings there. One such building, maybe the most beautiful of them all, is the Water Cube, the National Swimming Centre.
PTW (Peddle, Thorpe & Walker), CCDI (China State Construction Design International) and Arup won the international design competition to design and build the aquatic centre for the Beijing Olympics. A lighted cube, with a steel frame and transparent synthetic “bubbles” as skin, is situated next to the Olympic Stadium of Beijing, in the Olympic Green. It was inaugurated and delivered for use on the morning of January 28, 2008.
It took over four years to construct: the project’s ETFE (ethylene-tetra-fluoro-ethylene) air cushion structures are the first of their kind to be used in China and the largest and most complicated membrane system in any single project in the world (The Water Cube uses more than 100,000 sq. m. of ETFE). Many scientific and technical difficulties had to be overcome in order to make this amazing building. Among the achievements, nine important self-dependent innovations resolved world-class difficult topics related to the project’s steel structures, membrane structures and inner layout.
The NAC’s Games-time construction area is close to 80,000 square meters, containing 17,000 standard seats, including 6,000 permanent seats and 11,000 temporary ones. During the 2008 Olympic Games, it will produce 42 gold medals in swimming, diving and synchronized swimming. in addition to being a n aquatic competition venue, after the Olympics the centre will be converted into a multi-functional facility for sports, culture and recreation, featuring a “water setting” for people of Beijing.
The concept combines the symbolism of the square in Chinese culture and the natural structure of soap bubbles translated into architectural form. The result is a landmark building that uses state of the art technology and materials, is visually striking, energy efficient and ecologically friendly.
The “Water Cube” was built in accordance with a water-saving design concept to be a gigantic green architectural wonder. ETFE is much lighter than conventional glazing structures with the same lighting effect. So the cost of its supporting steel structure was reduced considerably. If made by a German company it would have cost 400-500 Euro per square meter, but the same material manufactured through a joint venture was only 2,000 Yuan per square meter. The conventional glass covering would have cost about 500 to 600 Euro.
In addition, the “Water Cube” was designed with water-saving and environmental protection efforts. According to statistics, the outer surface and roof façade can “collect” 10,000 tons of rain water, 70,000 tons of clean water and 60,000 tons of swimming pool water annually. And the venue can also save 140,000 tons of recycled water a year.
Other environmental design efforts covered an air-conditioning system, surface water exploitation and ventilation system.
The design was not without an intriguing story until it was finalised, you can read more about it in this article.
