  • Read the overview and definitions for the data set
  • On September 25, 2013, New York City released the 2012 energy and water use data for all properties required to annually benchmark under Local Law 84. New York City is the first in the nation to publicly disclose data for large multifamily buildings. Approximately a million New Yorkers can now see how much energy and water their apartment buildings consumed in 2012.

    The new data set includes more than 9,000 self-reported multifamily properties, effectively more than tripling the size of the first year's list. The data also represents the first year's results of both manual and automatic water benchmarking, with more than 6,800 properties reporting water data.

  • On September 4, 2012, New York City publicly posted the 2011 energy and water benchmarking results for non-residential properties covered under the benchmarking ordinance (Local Law 84). The list was updated on September 24th to account for discrepancies in building identification. Please make sure you are using the most up to date list. Also note that buildings were determined as non-residential by the New York City Department of Finance (DOF).

    New York City released its second report of benchmarking data, providing the first-of-its-kind year to year analysis of energy and water use in New York City's largest private sector buildings. Over 1.7 billion square feet of space was benchmarked and analyzed by building sector, borough, energy and water use, greenhouse gas emissions, fuel mix, and more.

    The second year results show strong data consistency from the previous year, supporting the quality and validity of the data submitted by thousands of building owners throughout New York City. Year to year analysis reveals various shifts in energy and water use, greenhouse gas emissions, and compliance rates, across multiple sectors. Case studies of a commercial office and a multifamily building show strong improvements at the individual building level and exemplify how benchmarking data can empower building occupants to implement cost effective retrofits.

    The New York City Local Law 84 Benchmarking Report (August 2012) is the first analysis of New York City benchmarking data collected as part of Local Law 84, which requires all privately-owned properties with individual buildings over 50,000 square feet or with multiple buildings with a combined square footage over 100,000 square feet to annually measure and report their energy and water use. 

    1.7 billion square feet of built space, which is equal to the built areas of Boston and San Francisco combined, was benchmarked in this effort. This constitutes the largest collection of benchmarking data gathered for a single jurisdiction and documents the current state of energy consumption and performance in large buildings in New York City. This data will also help identify opportunities to gain efficiencies. Similar reports will be produced on the benchmarking data compiled in each of the coming two years.

    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) submitted 2010, 2011 and 2012 benchmark results for City buildings to the Department of Finance (DOF) for publication. Since 2009, DCAS has worked with 28 agencies to benchmark almost 3,000 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.

    The City has published its benchmarking results for the 2013 calendar year.

     

    The City has published its benchmarking results for the 2012 calendar year. This report includes side-by-side comparisons between 2010 and 2012 for source Energy Use Intensity (EUI), ENERGY STAR rating, and total greenhouse gas emissions.

    Academic Reports


    Benchmarking Reports from Academic Partners

    Much of the analytical work of the benchmarking data was conducted by academic partners Dr. David Hsu, Assistant Professor in the Department of City and Regional Planning at the University of Pennsylvania, and by Dr. Constantine Kontokosta, Deputy Director of the New York University (NYU) Center for Urban Science and Progress (CUSP) and Founding Director of the NYU Schack Institute's Center for the Sustainable Built Environment. In addition to assisting the City write a more robust benchmark report, Dr. Hsu and Dr. Kontokosta also published their own reports.
