Green Roof Tracker

GSA has over 80 buildings equipped with green roofs, spanning approximately 2.2 million square feet. That is about 50 acres or 48 football fields of green roofs. This includes what is believed to be the second largest planted roof in the world: the U.S. Coast Guard Headquarters in Washington, DC, which is almost as large as ten football fields.
