What are Local Law 87 Energy Audits and Retro-Commissioning?

An Energy Audit is a survey and analysis of a building’s energy use to identify ways to minimize energy consumption without impacting operations.

The process of ensuring that the energy systems in an existing building install as intended, functionally tested, and capable of being run and maintained according to the owner’s operating demands is known as retro-commissioning.


A ten-year Energy Efficiency Report (EER) requires for all commercial, mixed-use, and residential buildings. Owners must submit their EER in the calendar year in which the year’s last digit corresponds to the building’s tax block number’s last digit.

EER-Required Properties. 

Buildings must submit an EER if they match any of the following criteria, which are based solely on the NYC Department of Finance’s ownership information records:

Buildings that have a gross square footage of more than 50,000

A tax lot with two or more structures totalling over 100,000 gross square feet.

Two or more condominium-owned designs that are larger than 100,000 square feet of gross space.

Exemptions need to report.

If you believe your building is not placed on the Covered Buildings List properly, please email the Department of Finance to dispute any of the following:

Square footage, number of buildings on a tax lot, ownership, address, or postal information along with your name, email address, and phone number.

For the following reasons, you can submit a Request to Update (RTU) property’s Gross Square Footage form via the NYC Department of Finance web portal:

If a property owner believes that it is not listed correctly on the Covered Buildings List (CBL) under Local Law 84/LL133 (Benchmarking) or Local Law 87 (Energy Audits and Retro-commissioning); or

If there is a problem with the property’s data on the CBL, it causes a discrepancy in the submission.

Instructions to access the online form:

1. Use your NYC.ID credentials to log into the portal (create a new account, if necessary).

2. Choose the RTU form for your property’s tax class (2 or 4) from the drop-down menu. The tax class for the BBL (Borough, Block, and Lot) number can be found in the Property Info section for the BBL number.

3. To verify your property and update the RTU form, enter the borough, block, and lot numbers. Line 5 on the form is for Gross Square Footage, which you should enter as accurately as possible for your property.


You should include an architect’s letter with the completed RTU as an official document for the DOF’s assessor to work with, although it is not required. You’ll get a confirmation receipt for your records when you file an RTU online.
