Local Law 84 Benchmarking

Benchmarking energy and water use allows owners, tenants and operators to better understand how their buildings are performing. By requiring annual benchmarking for certain city-owned and large privately-owned buildings, this law will give building owners and potential buyers a better understanding of a building’s energy and water consumption, eventually shifting the market towards increasingly efficient, high-performing buildings.

LL84 requires annual benchmarking data to be submitted by owners of buildings with more than 50,000 square feet for public disclosure by May 1. Note that the LL84 was amended in 2016 through Local Law 133. The new amendment lowered the threshold for individual private buildings. Beginning of 2018 onwards, individual buildings with at least 25,000 square feet of floor space will be required to perform benchmarking.


Benchmarking must be completed by May 1st to avoid $500 quarterly fines. Violation and penalty. Failure to benchmark by August 1, 2011, or by May 1 of subsequent years, may result in a penalty of $500. Continued failure to benchmark may result in additional violations on a quarterly basis and an additional penalty of $500 per violation.
