Prescriptive Data was selected by the U.S. General Services Administration (GSA) as one of four finalists in its Proving Ground program to promote energy efficiency within the GSA’s national real estate portfolio. This is the second time Prescriptive Data has been selected by the GSA to test out Grid-Interactive Efficient Building (GEB) concepts for the agency. As part of the GSA Proving Ground program, the agency works with independent, third-party evaluators to test out pre- and early-commercial building technologies in federally-owned buildings.
