Biggest Solar Building: Solar City, Dezhou, China

Designed to resemble a sundial, the world’s largest solar building opened in 2009. Its 800,000 square feet of space is festooned with thousands of solar panels and features exhibit halls, scientific research facilities, and the 180-room International Solar Micro-Emission Hotel, which utilizes solar power and “will leave you impressive memory forever,” according to the website. The building is rumored to have used less than 1 percent of the steel used in Beijing’s Olympic Bird’s Nest. —Adam H. Graham
