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.
In order to obtain whole building energy consumption data for benchmarking, building owners will need to obtain residential or non-residential tenant consumption data in addition to their base building data. If your property(ies) is/are not master-metered or you do not have whole building energy consumption data, the best way to acquire this information is to request it from utility companies.
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, Inc. (Con Ed)
- In order to guarantee that you receive aggregated consumption data in time to meet the May 1 deadline, Con Ed advises to submit your request no later than April 15, 2016.
- Con Ed provides aggregated consumption data for $102.50 per Building Block and Lot (BBL). Please check their web page for detailed instructions on how to request aggregated building consumption data.
- 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 22 2016.
- Please read the instructions (in PDF) for how to request aggregated energy data from National Grid.
PSEG Long Island (PSEG)
- 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, 2016.
- Please read the instructions (in PDF) for how to request aggregated energy data from PSEG.
Non-Residential Tenant Data Collection Form
As of January 2014, the Mayor's Office of 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.
Department of Environmental Protection (DEP)
The Department of Environmental Protection (DEP), manages New York City’s water supply and wastewater treatment, and provides all water consumption information to properties eligible and covered under LL84. Only covered properties that have had an Automatic Meter Reader (AMR) installed for at least the entire calendar year will be required to benchmark their water consumption.
Building owners that benchmarked their data prior to 2016 by registering in Portfolio Manager® for automatic DEP water consumption data uploading do not need to re-register again this year. Water consumption data for those properties will be automatically uploaded for every year moving forward. Please note that data is uploaded in cubic feet.
If your property(ies) has/have not yet registered to benchmark water and is in the Covered Buildings List, log into Portfolio Manager® and share your property information with DEP.
- Please read the instructions (in PDF) for how to get automated water data from DEP.
- If your property(ies) is/are not eligible for automated water benchmarking, you have the option to benchmark water data manually. Please read the instructions (in PDF) for how to get manual water data from DEP.
- Common web services errors are listed here.
All inquires about water benchmarking should be directed to the Department of Environmental Protection at email@example.com.
