The Energy Efficient Buildings Hub (EEB Hub) was established in Philadelphia by the U.S. Department of Energy (DOE) as an Energy-Regional Innovation Cluster (E-RIC) on February 1, 2011 with a unique dual mission of improving energy efficiency in buildings—literally re-energizing them for the future—and promoting regional economic growth and job creation from our headquarters in Philadelphia’s Navy Yard, one of the nation’s largest and most dynamic redevelopment opportunities.
