CoStar Group is actively involved in building awareness of energy efficiency within the commercial property sector. One way CoStar has taken initiative in this area is by identifying all commercial buildings that qualify for the U.S. Environmental Protection Agency’s ENERGY STAR rating -- one of the most recognized national metrics for evaluating energy efficiency -- within its online database of commercial property. CoStar also designates properties that are certified through the Leadership in Energy and Environmental Design (LEED) program of the U.S. Green Building Council.
