Local Law 87 Compliance – Here Is How It Can Help with Your Local Law 97


The Greener, Greater Buildings Plan came into existence in 2009 to enhance the energy efficiency of NYC buildings. Several regulations, including Local Law 87 and Local Law 97, come under this act. Even though LL87 and LL97 are two different laws, complying with one can help with another. Scroll through this article to learn more about LL87 and how it can help in complying with LL97.

Complying with Local Law 87

Large buildings need to fulfill the following for LL87 compliance until they fall under any exception criteria:

1. Energy Audit

Building owners must rely on energy audits to recognize every opportunity to save energy. An Energy Audit needs to assess every base building system. The base building systems include HVAC, hot water, electricity, and lighting systems. A certified energy auditor needs to perform or supervise the audit, and it should be of at least ASHRAE Level 2.

2. Retro-Commissioning

After identifying the deficiencies during the energy audit, building owners should perform retro-commissioning. The purpose of retro-commissioning is to ensure that all building systems follow the stringent measures under section 28-308.3 of local law 87. The criteria under section 28-308.3 include the following:

● HVAC sequencing and calibration of lighting and hot water systems
● Washing, repairing, and maintenance of HVAC equipment, pipes, and boiler room components
● Training of maintenance professionals
● Documentation of permits and manuals for electrical, HVAC, and plumbing equipment

Apart from the criteria mentioned here, retro-commissioning includes various other things. Only certified and approved professionals are eligible for performing retro-commissioning.

3. Energy Efficiency Report

After energy audits and retro-commissioning, building owners need to submit detailed energy efficiency reports. A comprehensive EER for LL87 compliance will include the following:

● Energy saving calculations
● Several initiatives for energy conservation
● How to implement energy efficiency recommendations
● A cost-benefit analysis

The last date for submitting an energy efficiency report is December 31 of the year it is due. If you want to understand the year your report is due, you should check the last digit of your block number. Building owners need to submit the energy efficiency report once every ten years.

Relationship Between Local Law 87 and Local Law 97

LL87 is applicable for buildings over 50,000 sq ft. LL87 compliance requires buildings to perform energy efficiency audits and retro-commissioning every 10 years. Non-compliance with local law 87 can cause hefty fines.

Meanwhile, Local Law 97 is focused on reducing greenhouse gas emissions in New York City. The goal is to reduce 80% of carbon emissions in NYC by 2050. When buildings undertake measures to avoid LL87 fines, it automatically puts you on the right path towards Local Law 97 Compliance.
