Intro to LL87 Compliance: Energy Audits & Retro-commissioning


Local Law 87 (LL87) mandates that buildings over 50,000 gross square feet undergo periodic energy audit and retro-commissioning measures, as part of the Greener, Greater Buildings Plan (GGBP). 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.

In addition to benchmarking annual energy and water consumption, energy audits and retro-commissioning will give building owners a much more robust understanding of their buildings’ performance, eventually shifting the market towards increasingly efficient, high-performing buildings.

In summary, LL87’s energy audit and retro-commissioning process requires the following:

1. Determine if a building needs to comply, and what year it is due.

2. Conduct an energy audit and retro-commissioning of base building systems and complete an Energy Efficiency Report (EER) electronically.

3. Submit the EER once every ten years to the City by December 31.

How to Comply

In order to achieve LL87 Compliance, owners of covered buildings as designated by the Covered Buildings List must submit their Energy Efficiency Reports (EER) to the City by December 31 of the year they are due, once every ten years.
