Energy Audits

​

Local Law 87

LL87 mandates that buildings over 50,000 gross square feet undergo periodic energy audit and retro-commissioning measures. The intent of this law is to inform building owners of their energy consumption through energy audits, which are surveys and analyses of energy use, and retro-commissioning, the process of ensuring correct equipment installation and performance. 

​

Energy Efficiency Reports are due in the calendar year with a final digit that is the same as the last digit of the building's tax block number. A building's energy audit and retro-commissioning work must be completed prior to filing the Energy Efficiency Report.

​

Local Law 84

The NYC Benchmarking Law requires owners of buildings that meet the criteria outlined in the law to annually measure their energy and water consumption through a process called benchmarking. Building owners must submit the usage data to the City by May 1st of every year.

​

2. The energy efficiency grade will be made available by the NYC Department of
Buildings every year on October 1.
