LL88: Lighting Upgrades & Sub-metering

Lighting in non-residential buildings accounts for almost 18 percent of energy use and greenhouse gas emissions in New York City buildings. Dramatic improvements in lighting technology over the past two decades have made it feasible to significantly reduce energy consumption by installing more efficient lighting systems that can yield significant cost savings.

Additionally, many buildings depend on a single meter to monitor electricity consumption, and as such, bill non-residential tenants a standard rate regardless of the tenant's actual consumption. Individual tenants would likely reduce their energy consumption if energy use information were made available to them regularly. Local Law 88 of 2009 (LL88), part of the 
Greener, Greater Buildings Plan (GGBP), brings together requirements for both lighting upgrades and sub-metering that will help buildings achieve significant energy savings. Please review this section to learn more about LL88, how to comply, and where to get help.

About LL88
LL88 of 2009—and its subsequent expansions with Local Law 132 and 134, both of 2016—requires common areas in residential buildings greater than 25,000 square feet and all areas in non-residential buildings greater than 25,000 square feet to upgrade lighting to meet current New York City Energy Conservation Code standards by 2025. The original law and its subsequent expansions also requires all non-residential buildings greater than 25,000 square feet to install electrical sub-meters for each large non-residential tenant space greater than 5,000 square feet and provide monthly energy statements. The compliance deadline for both the lighting and sub-metering requirements is 2025.
