When you think about a “green” building, you probably don’t picture a centuries-old National Historic Landmark that’s lined with columns and made of thousands of tons of granite.That may be about to change.

I'm pleased to announce that the Treasury Building – which dates to the 19th century and is located right next door to the White House – received Leadership in Energy and Environmental Design (LEED) Gold certification from the U.S. Green Building Council (USGBC).
