Energy and Water Data Collection



Local Law 84 (LL84) requires building owners to report data on annual energy and water usage. Click on the section titles below to review how to obtain both types of data.

Energy Data Collection
In order to obtain whole building energy use for benchmarking, building owners will need to obtain residential or non-residential tenant consumption data. There are two ways to acquire information; requesting from tenants or requesting from utilities.

Aggregated Energy Data for All Buildings
A building owner can obtain aggregated energy data (a building's entire electric and gas consumption measured by month) from a private utility. The following utilities offer aggregated consumption data:

Consolidated Edison (Con Ed)


National Grid

  • In order to guarantee that you receive aggregated consumption data in time to meet the May 1 deadline, National Grid advises to submit your request no later than April 25, 2014.
  • National Grid offers two ways to request aggregated consumption data: via email or phone:
    • Download the National Grid request for aggregated energy data (in PDF).
    • National Grid requires building owners to obtain authorization from their tenants to release historical gas consumption usage and billing information.
    • Download the Authorization Form (in PDF) available as a template that building owners must sign and submit with the data request.

PSEG Long Island

  • In order to guarantee that you receive your aggregated consumption data in time to meet the May 1 deadline, PSEG advises you submit your request no later than April 15, 2014.
  • PSEG Long Island, which now manages former Long Island Power Authority (LIPA) covered buildings, has established a process for electricity data aggregated requests. All requests must be made in writing, via postal mail or fax:

Non-Residential Tenant Data Collection Form
As of January 2014, the Mayor's Office of Long-Term Planning and Sustainability will not require building owners to issue a data collection request form to non-residential tenants. Building owners are strongly encouraged to request aggregated data directly from the utility companies.

Water Data Collection

Starting February 11, 2014, automatic water uploading was made available again for 2013 water usage reporting.

The Department of Environmental Protection (DEP) acts as the New York City water utility and provides all water consumption information. Covered buildings that have had an Automatic Meter Reader (AMR) installed for at least the entire calendar year of 2013 will be required to benchmark their water consumption. To see if your building is covered, refer to the Covered Buildings (Buildings Required to Benchmark) page.

"Automated Benchmarking Services" (ABS) has been re-named "Web Services" within Portfolio Manager and is now available for 2013 water data reporting. This feature allows DEP to upload your building’s annual water consumption directly into Portfolio Manager.  Click the links below for guidance on setting up Web Services within Portfolio Manager:

Users also have the option to manually enter their water usage.
