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
Energy Data Collection
Water 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.
Non-Residential Tenant Data Collection Form
Under LL84 section 28-308.4.1, a building owner must first request information from separately metered non-residential tenants by issuing a request form in person, by mail, via email, etc.

Aggregated Energy Data for All Buildings
If a building owner is unable to receive information from separately metered tenants, he or she 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) provides aggregated consumption data for $102.50.
- National Grid offers two ways to request aggregated consumption data: via email or phone
Water Data Collection
Note: Portfolio Manager was offline and unavailable from June 26 through July 16 to undergo upgrades. The new upgraded tool was launched on July 17, but automatic water uploading is currently unavailable. The City encourages users to input their water usage manually, following the guidance posted below. Continue to check back to this section for revised guidance information.
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 2012 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.
Before the upgrade of Portfolio Manager in July 2013, users could utilize the Automated Benchmarking Services (ABS) within Portfolio Manager to directly upload water usage courtesy of the Department of Environmental Protection (DEP).The ABS system has been re-named "Web Services" within Portfolio Manager, and is unavailable for use until further notice. Therefore at this time, the tutorial for requesting automatic water benchmarking has been removed.
The City encourages those AMR-covered properties to manually enter their water usage, following the revised "Manual Water Benchmarking Tutorial":
