In commercial buildings, space heating, cooling, and ventilation account for 34 percent of energy used on site and 31 percent of primary energy use, according to the U.S. Department of Energy. The Green Proving Ground program selected multiple innovative HVAC technologies to investigate their usefulness, effectiveness, and applicability across the GSA portfolio.
