In its pursuit of ambitious sustainability goals, New York City has set a formidable agenda: generating 50% of its energy from renewable sources by 2030 and slashing emissions by 80% by 2050, compared to 2005 levels. With approximately a million buildings in the city, a targeted approach becomes essential.

LL88 focuses on enhancing lighting efficiency and providing commercial tenants with transparent insights into their energy consumption through upgraded lighting systems and mandated sub-metering. This applies to “covered buildings” exceeding 25,000 square feet, compelling them to upgrade their lighting systems to meet specified energy efficiency standards. Smaller residential buildings (R-2 and R-3 occupancy types) are exempt. Buildings have until January 1, 2025, to comply. Exempt buildings must file lighting reports with the New York City Department of Buildings.


The key provisions encompass:

  • Implementation of Advanced Lighting Control Systems: Building owners must install sophisticated lighting control systems facilitating efficient operation, incorporating features such as occupancy sensors, timers, automatic shutoff switches, light reduction technologies, tandem wiring, and daylight-responsive controls.
  • Replacement of Outdated Lighting Fixtures: The law mandates the replacement of obsolete lighting fixtures, such as incandescent or fluorescent lamps, with energy-efficient alternatives like Light Emitting Diodes (LEDs).
  • Submetering of Tenant Spaces: To enhance accountability and promote better energy management, LL88 mandates the submetering of tenant spaces in multi-tenant buildings exceeding 5,000 square feet. Tenants must receive monthly statements outlining electricity usage and charges.
  • Reporting Requirements: Building owners are required to submit energy efficiency reports to the Department of Buildings, outlining compliance with LL88 and providing comprehensive data on energy consumption and savings.

Compliance with LL88 represents a significant investment for building owners, yet the long-term benefits are considerable. Upgrading lighting systems reduces energy costs, improves building performance, and enhances tenant satisfaction—moreover, adherence to LL88 positions building owners as active contributors to the city’s sustainability efforts.
