New Beijing Airport to be World’s Largest

China is building a new airport in Beijing that is expected to be open in time for the 2008 Olympics. At over a million square meters, and an expected 53 million passengers per year, it will surely become the world’s largest and most technologically advanced. “It was built using sustainable design principles,” according to Business Week, “including southeast-oriented skylights (to maximize heat from early sunshine) and an integrated environment-control system that uses minimal energy.” Check out the gallery below.
