NYC LOCAL LAW 84
The Benchmarking Law
Local Law 84 is a law passed by the New York City Council. It is part of a series of city regulations designed to reduce greenhouse gas emissions and protect the environment. The law requires all buildings in the five boroughs over 25,000 square feet to submit annual data on energy usage for the previous year by May 1.
Your building will receive an efficiency rating score (A through D) that takes the form of a colorful label that is posted near the door of the building.
In order to comply with Local Law 84, building owners must use ENERGY STAR Portfolio Manager to calculate the Greenhouse Gas (GHG) emissions based on a building's consumption data. The ENERGY STAR score will be used to define the building’s Energy Efficiency Rating, or Energy Grade as per NYC Local Law 95.
