What Is Local Law 87?
Enacted in 2009 as part of New York City’s sustainability initiatives, Local Law 87 mandates energy audits and retro-commissioning every 10 years for large buildings. This law helps identify inefficiencies in energy use and ensures building systems operate as intended, supporting NYC’s broader goal to reduce greenhouse gas emissions and increase energy efficiency citywide.
Key Terms Defined:
- Energy Audit: A detailed analysis of a building’s energy usage, identifying actionable opportunities to reduce consumption while maintaining performance.
- Retro-commissioning: Ensures energy systems are functioning as designed and meet operational needs efficiently.
Who Does It Apply To
LL87 NYC applies to the following types of buildings in NYC:
- Buildings larger than 50,000 gross square feet.
- Tax lots with two or more buildings exceeding 100,000 gross square feet in total.
- Condominium complexes with multiple buildings collectively exceeding 100,000 gross square feet.
Check your compliance status using the Covered Buildings List for 2024.
What Is Required and When?
Building owners must submit an Energy Efficiency Report (EER), summarizing the findings from the energy audit and retro-commissioning. The submission deadline is tied to your building’s tax block number.
Steps to Comply:
- Conduct an energy audit using the Energy Audit Template Tool.
- Complete retro-commissioning using the Retro-Commissioning Reporting Tool.
- Submit the EER to the NYC Department of Buildings at LL87@buildings.nyc.gov.
Extensions and deferrals may be available for eligible buildings. Learn more about deferral eligibility.
Failing to file the EER on time results in significant penalties:
- Initial Year: $3,000 per month.
- Subsequent Years: $5,000 annually.
By working with NECS, you can avoid these costly penalties while enhancing your building’s performance and energy efficiency.
