Olympics 2008: National Aquatics Centre (The Water Cube)

This is the brilliantly bizarre-looking National Aquatics Centre, which is better known as The Water Cube. The building is perhaps best described as resembling some sort of “bubble cake”, and when it’s lit up, it looks pretty incredible.

During the Beijing Olympics the centre will host the Swimming, Diving and Synchronised Swimming events, and is situated within Olympic Green, right next to the Bird’s Nest Stadium where the opening ceremony was held on Friday.¹

The design of the steel space-frame that makes up the building is actually based on a theory originally posited by great Victorian physicist Lord Kelvin. The idea was further developed in the 90s, and suggests that a combination of dodecahedra and tetrakaidecahedra (12 and 14-sided shapes respectively) can be used to divide space into cells of equal volume with the least surface area between them. In the case of the aquatic centre, thus maximising the amount of light entering the building, and helping to reduce the cost of heating the pool!

The frame is wrapped in a transparent form of Teflon called ETFE, and the building is the largest ETFE clad structure in the world - bigger even than the world’s largest greenhouse, the previously featured Eden Project. ETFE allows more light and heat penetration than traditional glass - apparently accounting for an equivalent 30% decrease in heating costs.
