Local Law 87: Audit & Retro-Commissioning


Local Law 87 is an energy audit and retro-commissioning report combined to be an Energy Efficiency Report (EER). The EER will be due once every 10 years after the initial report, unlike Local Law 84, which is due yearly. The EER will include an ASHRAE Level II audit report with recommendations on energy efficiency measures. For the retro-commissioning portion of the EER, R3 Energy reviews all building system operations, identifying any deficiencies and complying with all aspects of the law.

ASHRAE Level II Audit R3 Energy will perform an ASHRAE Level II Audit to comply with the Audit portion of Local Law 87. This will include:
  • On-site audit by MFBA auditors or CEM, dependent on type of building
  • Supervision of auditors by PE or registered DOB individual
  • Audit findings to be input into EER

Retro-Commissioning
  • On-site retro-commissioning team will include the qualifications of agents, including: PE, ACAP, and/or registered DOB individual
  • The law is requiring HVAC balancing. If the building needs HVAC balancing, the cost will have to be paid separately to a certified individual meeting LL87 requirements: (ex. Certified Test and Balance from NEBB)
  • Exceptions to retro-commissioning include LEEd buildings; please inquire on exemption if your building is LEED certified.

Submission
  • The EER in completion will be reviewed by the building owner for final approval and then submitted to the city for PlaNYC requirements by the applicable deadline for each building.
