New York Local Laws

Local Laws enacted by the state of New York to ensure a Greener tomorrow.   

Local Law 88

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.

Local Law 97

Passed by the New York City Council in 2019, Local Law 97 calls for large existing buildings in NYC to reduce their emissions by 40% by the year 2030. The ambitious law calls for those buildings to cut emissions by a total of 80% by 2050.

This law is part of the Climate Mobilization Act, which is a package of bills aimed at reducing the greenhouse gas emissions of New York City. The end goal is to bring the City to a carbon neutral state by 2050.

Local Law 87

Requires buildings to undertake the audits that lead to energy efficiency retrofits, which generally result in major cost and energy savings. Local Law 87 (LL87) mandates that buildings 50,000 gross square feet or larger undergo periodic energy audit and retro-commissioning measures, as part of the Greener, Greater Buildings Plan (GGBP).


Real Time Energy Management (RTEM) combines technology and services to act as the functioning brain of a building. RTEM technology sends a building's live performance data to a cloud-based system, where it is transformed into actionable insights for property owners, building managers, and tenants.
