Local Law 87 (LL87) in New York City

BSE Local Law 87 (LL87) in New York City

Local Law 87 (LL87) is a legislation enacted by the City of New York as part of its ongoing efforts to reduce energy consumption and greenhouse gas emissions. LL87 specifically focuses on improving the energy efficiency of existing buildings in the city. It requires owners of large buildings to conduct energy audits and retro-commissioning activities at prescribed intervals.

Here are the key components of Local Law 87

Energy Audits: Building owners are required to conduct energy audits of their properties every ten years. These audits evaluate the building’s energy usage and identify potential areas for improvement, such as upgrading lighting systems, improving insulation, or optimizing HVAC systems.

Do the energy audits need to be certified?

Yes, the energy audits conducted under Local Law 87 (LL87) in New York City must be certified. The certification ensures that the audits meet the required standards and provide accurate and reliable information regarding the building’s energy usage and potential efficiency measures.

The certification process involves engaging a licensed and qualified professional or firm to conduct the energy audit and review the findings. These professionals typically possess expertise in energy analysis, building systems, and energy efficiency measures. They will evaluate the building’s energy performance, assess its systems and equipment, analyze utility bills, and identify areas where energy savings can be achieved


Retro-Commissioning: In addition to energy audits, LL87 mandates retro-commissioning, which involves optimizing the performance of building systems to improve efficiency. This process ensures that all mechanical, electrical, and control systems are functioning optimally and aligned with the building’s operational needs.

While having a Certified Commissioning Professional (CCP) perform retro-commissioning for Local Law 87 (LL87) compliance in New York City is not explicitly required, it can be highly beneficial. The CCP certification demonstrates a professional’s expertise and competence in commissioning processes, including retro-commissioning.


Filing Energy Efficiency Reports: Following the energy audit and retro-commissioning, building owners are required to file Energy Efficiency Reports (EERs) with the New York City Department of Buildings (DOB). These reports summarize the findings of the energy audit, retro-commissioning process, and any subsequent measures taken to enhance energy efficiency.

Compliance and Penalties

Building owners must ensure compliance with LL87 by completing the energy audit, retro-commissioning, and filing the EERs within the designated deadlines. Failure to comply with LL87 can result in penalties and fines imposed by the DOB.

The primary goal of Local Law 87 is to identify opportunities for energy efficiency improvements in existing buildings, which account for a significant portion of energy consumption and greenhouse gas emissions in New York City. By enforcing audits, retro-commissioning, and reporting, the law aims to drive energy savings, reduce environmental impact, and enhance the overall sustainability of the city’s building stock.

It is important for building owners to familiarize themselves with the requirements of Local Law 87 and ensure compliance to avoid penalties. Additionally, engaging qualified energy consultants and professionals can assist in conducting energy audits, implementing efficiency measures, and navigating the compliance process.
