Local Law 84 (LL84) is New York City’s annual energy and water benchmarking requirement, part of the city’s Greener, Greater Buildings Plan. It requires owners of covered buildings to report their building’s energy and water consumption each year using the EPA’s ENERGY STAR Portfolio Manager tool.
Any building over 25,000 gross square feet, and lots with two or more buildings totaling more than 100,000 square feet combined, are required to benchmark under LL84.
Benchmarking data must be submitted by May 1 each year, covering the prior calendar year’s energy and water usage.
Buildings that miss the May 1 deadline face a civil penalty of $500 per quarter that the report remains outstanding, up to $2,000 per year. Buildings must also display their Building Energy Efficiency Rating, and failing to do so carries a separate penalty.
LL84 benchmarking data is the foundation for Local Law 97 compliance. Your reported energy and water usage under LL84 feeds directly into the emissions calculations used to determine LL97 penalty exposure, so accurate, error-free benchmarking data matters for both laws.
