San Francisco Airport has revealed its renovated Terminal 2, which aims to be the first LEED Gold-certified airport terminal in the U.S. Featuring 90 percent recycled building materials from the original terminal that opened in 1954, Gensler-designed SFO Terminal 2 wants to lead the way by example for other U.S. airports looking to go green. But that’s just for starters. The new terminal also wants to make travelers more comfortable while they reduce waste.
