Local Law 84: Benchmarking (LL84) requires large buildings to comply with benchmarking regulations. These buildings include private sector buildings that are larger than 50,000 square feet, and two or more private sector buildings on a single lot that are larger than 100,000 square feet.

NOTE: Gross square footage (GSF) listed by the New York City Department of Finance (DOF) are estimates solely for identifying buildings under LL84; when inputting information, building owners must calculate true gross square area, as defined by the Benchmarking Rule. 

Water Data Collection
Covered buildings that have an Automatic Meter Reader (AMR) installed for at least the entire year of 2012 are required to benchmark water in addition to energy usage.

To check if your building meets these requirements, please see the latest covered buildings list below.
