What Are Local Law 84 & 133?
New York City's energy benchmarking laws, also commonly referred to as Local Law 84 and 133, require owners of buildings greater than 25,000 square feet to file a report by May 1st each year on their energy use, and for some buildings also water use. Due to technical issues, the May 1st, 2018 filing deadline for calendar year 2017 data was postponed for a portion of buildings until December 31, 2018.
The report needs to contain 12 months of utility data on a building's electricity, natural gas, oil and water consumption. Based on this information, a building's energy performance is then compared to the performance of other similar buildings in a benchmarking process.
