This is a virtual tour of the U.S. Green Building Council's headquarters in Washington, D.C. (Note: you'll need the Google Earth plugin installed to view).
This project is cool for lots of reasons. For starters, USGBC's 75,000-square-foot facility is loaded with efficient and innovative green features that have earned the building a LEED Platinum rating. Professionals regularly tour the USGBC for real-world examples of successful green practices.
