NYC Benchmarking Law

The NYC Benchmarking Law requires owners of large buildings to annually measure their energy and water consumption in a process called benchmarking. The law standardizes this process by requiring building owners to enter their annual energy and water use in the U.S. Environmental Protection Agency's (EPA) online tool, ENERGY STAR Portfolio Manager® (opens in new window) and use the tool to submit data to the City. This data informs gives building owners about a building's energy and water consumption compared to similar buildings, and tracks progress year over year to help in energy efficiency planning.

Benchmarking data is also disclosed publicly, analyzed in reports, visualized in the NYC Energy and Water Performance Map, included in energy efficiency policy development efforts such as the Buildings Technical Working Group Final Report, and used to develop free resources such as the NYC Retrofit Accelerator and Community Retrofit NYC to help building owners use less energy and save money. 

SERVICE UPDATE: Local Law 133 of 2016 amended the Administrative Code of the City of New York in relation to expanding the list of buildings required to benchmark for energy and water efficiency.  In addition, as of October 31, 2016, the term ‘covered building’ shall not include real property, not more than three stories, consisting of a series of attached, detached or semi-detached dwellings, for which ownership and the responsibility for maintenance of the HVAC systems and hot water heating systems is held by each individual dwelling unit owner, and with no HVAC system or hot water heating system in the series serving more than two dwelling units (also known as ‘garden style’ apartments).

The annual benchmarking process consists of the following steps:

  1. Check the Covered Buildings List for your property every year.
  2. Set up an account in ENERGY STAR Portfolio Manager® if you do not have one.
  3. Enter or review building characteristics and uses.
  4. Collect whole building energy data (and water data, if required) from utilities.
  5. Record your energy and water usage in Portfolio Manager®.
  6. Confirm and enter BBL and BIN information.
  7. Check your data for errors and completeness.
  8. Submit usage data to the City by May 1 through Portfolio Manager®.

Building owners are subject to a penalty if usage data is not submitted by May 1 every year.
