The General Services Administration announced January 24 that it will soon release a recommendation on the federal government’s use of green building rating systems. The Energy Independence and Security Act of 2007 requires the agency to review the government’s use of green building certification systems every five years, and the agency is reviewing three rating systems: the Leadership Energy and Environmental Design program, which is currently used; the Green Building Initiative’s Green Globes; and the International Living Future Institute’s Living Building Challenge.
