NBBJ, in collaboration with CCDI for structural design, designed the Hangzhou Tennis Center.
One of NBBJ's goals was both environmental and cost-saving: to reduce the amount of steel used in the structure's envelope. They did so, now boasting a 67% steel savings over similar arenas.
Grasshopper was first used to generate an accurate logarithmic design for the shell. The generated double curve surfaces took a form of petals. Grasshopper was used for the model to convert the petals to structural elements.
The Hangzhou Tennis Center, located in Hangzou, China, is scheduled for completion in 2015-2016.
Arch20 featured the project on their web site as a study of computational design.
