NYC's de facto green building code combines the NYC Energy Conservation Code with the Greener Greater Buildings Plan: Local Law 84 benchmarking, Local Law 87 energy audits, Local Law 88 lighting and submetering, and Local Law 97 emissions caps.
The NYC Energy Conservation Code (Admin Code Title 28 Chapter 10) adopts the 2020 NYStretch and 2024 NYC ECCC, exceeding ASHRAE 90.1 by 10 to 20 percent. Local Law 84 of 2009 (Admin Code section 28-309) requires annual benchmarking through Energy Star Portfolio Manager for buildings over 25,000 square feet. Local Law 87 of 2009 (section 28-308) mandates a decennial ASHRAE Level II energy audit and retro-commissioning. Local Law 88 of 2009 (section 28-310) requires lighting upgrades and tenant submetering by 2025. Local Law 97 of 2019 layers carbon caps on top.
Failure to file LL84 reports costs $500 per quarter under Admin Code section 28-309.12. Missing the LL87 audit incurs $5,000 the first year and $5,000 every subsequent year. LL88 lighting non-compliance and LL97 overages add separate stacked fines.
