We can't tell you where it is or we'd have to kill you, but the newest CIA campus somewhere in northern Virginia is winning kudos for being green. Built from more than 20 percent recycled materials and sporting features like waterless urinals and a roof covered in vegetation, two buildings on the site have earned a gold certification from the U.S. Green Building Council's Leadership in Energy and Environmental Design, or LEED, ratings system. The campus, which we hear will process new job applicants, should consume about 21 percent less energy and 40 percent less water than a conventional building. "We even saved on materials for a sign," kids a source, "because there ain't one." A weird footnote: The secret site has a "visitor center."
