The Greater Philadelphia Innovation Cluster (GPIC) for Energy-Efficient Buildings, a U.S. DOE Energy Innovation Hub led by Penn State University. Located at The Navy Yard in Philadelphia, the goals of the GPIC are to improve energy efficiency and operability and reduce carbon emissions of new and existing buildings, and to stimulate private investment and quality job creation in the Greater Philadelphia region, the larger Mid Atlantic region, and beyond. The GPIC will focus on full spectrum retrofit of existing average size commercial and multi-family residential buildings.
