Local Law 87 (LL87) is an energy-efficiency measure that requires that buildings larger than 50,000 gross square feet undergo regular energy audits and retro-commissioning measures as part of the Greener, Greater Buildings Plan (GGBP). The GGBP has been designed to proactively address energy waste in existing buildings, particularly in larger structures that contribute to a greater proportion of New York City’s total energy use.

These larger facilities tend to have more sophisticated management and more financial and technical resources when compared to smaller buildings. The GGBP and LL87 aim at enacting energy-saving measures, such as the use of energy-efficient appliances in larger buildings, throughout New York City. Ultimately, the goal is to ensure that key decision-makers have access to vital information to understand energy use and pursue energy-efficiency measures.


Achieving Energy Efficiency

To accomplish this goal, LL87 requires regular energy audits in the form of surveys and analyses of energy use and retro-commissioning. Retro-commissioning is the process of ensuring optimal equipment installation, performance, and maintenance.

Along with benchmarking annual energy and water consumption, these energy audits and retro-commissioning reports aim to give building owners a much more robust understanding of their buildings’ performance and eventually shift market norms toward increasingly efficient, high-performing buildings.

To ascertain if and how LL87 affects you and your business, you must:

  1. Determine if your 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 your EER once every 10 years to the city by December 31.


Who Needs To Comply?

If you’re a building owner, you first need to determine whether you fall under the mandates of LL87. You’re required to comply with LL87 if you have a Covered Building, which means one or more of the following:

  1. Building exceeds 50,000 gross square feet
  2. Two or more buildings on the same tax lot together exceed 100,000 gross square feet
  3. Two or more buildings held in the condominium form of ownership that is governed by the same board of managers and together exceed 100,000 gross square feet

What Systems Are Audited?

LL87 mandates that the following building systems are subject to inspection and auditing:

  • The building envelope
  • HVAC (heating ventilation and air conditioning) systems
  • Conveying systems
  • Domestic hot water systems
  • Electrical and lighting systems

If your building falls under the authority of LL87, you must submit Energy Efficiency Reports (EER) to the New York City government by December 31 of the year they are due (once every 10 years). [The chart on this page] can help you determine which year your first EER is due.

EERs must include information on the following:

  • Basic team information
  • General building information
  • Existing equipment inventory
  • Energy end-use breakdown
  • Energy conservation measures identified from the audit
  • Retro-commissioning measures
