For many stadiums and arenas, there is often a tradeoff between sustainability, performance and iconic design. Hangzhou Sports Center unites all three, featuring a poetic, floral-inspired design that simultaneously reduces carbon and material use. The development uses 67% less steel than Beijing Olympic Stadium, making it both beautiful and sustainable while creating a world-class sporting venue for a booming city.
New construction has tripled Hangzhou’s size in the past decade, resulting in a modern architectural fabric that is powerful in scale, yet still in need of public space. As part of the city’s riverfront development, NBBJ in partnership with CCDI has designed the Hangzhou Sports Park to be a vibrant, sustainable, pedestrian-centric recreation development.
To save resources and create flexibility, the design team employed computational scripts to reduce steel: 1) by linking the steel shell and concrete bowl together at each level so the two systems work in unison; and 2) by providing additional structure at the bowl’s top to reduce the roof cantilever. In addition to using 67% less steel than Beijing Olympic Stadium, the design team also addressed sustainability through the site response. The overall planning of the complex makes use of porous, light colored surfaces, green park spaces and below-grade parking to decrease water runoff from the site and reduce the heat island effect.
To provide a destination for fans and the community before, during and after games, the entire sports center serves as a recreational park for the business district along the Qiantang River. The site’s flowing circulation creates a seamless three-level pedestrian experience that unites the main stadium and tennis court.
