London 2012 Velodrome (London, United Kingdom: 2012)
There’s a lot more serious building happening above this cycling track than its nickname, the Pringle, suggests. Hopkins Architects went into high gear to sculpt a record-setting track, but didn’t ignore green concerns. By utilizing rainwater collection, a canopy that lets in natural daylight, and a cable-supported roof that reduces steel usage, the building is both sturdy and sustainable.
