    Benchmarking Data Disclosure and Report for City Government

    As part of the Greener, Greater Buildings Plan, the New York City Department of Citywide Administrative Services (DCAS) annually submits benchmarking results for City buildings to the Department of Finance (DOF) for publication. Since 2009, DCAS has worked with 28 agencies to benchmark roughly 4,000 buildings, including libraries, police stations, firehouses, schools, courthouses, health, community and family centers, and government offices.

    Benchmarking measures the total electricity, natural gas, district steam and heating fuel oil consumed in a building and adjusts for other factors so that the City can understand which facilities are operating inefficiently. This information allows the City to prioritize buildings for energy efficiency investments and to monitor building performance over time.
