LL88: Lighting Upgrades & Sub-metering

Lighting in non-residential buildings accounts for almost 18 percent of energy use in New York City buildings and roughly 18 percent of the city's carbon emissions from 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. Many such investments will typically be paid for through operational 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 (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 requires large non-residential buildings to upgrade lighting to meet current New York City Energy Conservation Code standards, and to install electrical sub-meters for each large non-residential tenant space and provide monthly energy statements.
