Overview

LL 88 mandates large non-residential buildings (buildings greater than 50,000 square feet) to upgrade their lighting to meet current New York City Energy Conservation Code (NYCECC) standards at least once by January 1, 2025. The intent is to enable investment in newer efficient lighting systems that will reduce energy consumption and carbon emissions. This law also mandates that one or more sub-meters be installed in buildings for each:

  1. Non-residential tenant space of 10,000 gross square feet or more leased to the same person
  2. Floor larger than 10,000 gross square feet consisting of tenant spaces leased to two or more different persons

LL 88 further requires that buildings provide monthly energy usage statements to their tenants, who are billed only for their own usage, to encourage energy conservation.
