LEED® Law (Local Law 86)

The City of New York firmly established its commitment to green building by passing one of the nation's first green building laws, Local Law 86 of 2005 (LL86). LL86 requires that building projects receiving more than a specified amount of City funding achieve a Leadership in Energy and Environmental Design (LEED®) rating level of Certified or Silver (depending on building type) and/or reductions in energy cost and potable water use. The law's numerous benefits collectively support the sustainability goals of both PlaNYC and 30x17.

LL86's Impacts
Administered by the New York City Mayor's Office of Environmental Coordination (MOEC), LL86 has had a significant impact on the work of various City agencies since its enactment in 2005. The New York City Department of Design and Construction's (DDC) growing list of completed and ongoing projects demonstrates the successful balance of meeting clients' needs, integrating with existing surroundings and following the sustainable green building standards adopted by the law. New public school building projects being constructed under LL86 by the New York City School Construction Authority (SCA) and the New York City Department of Education (DOE) are creating energy-efficient and healthy learning environments. The New York City Department of Citywide Administrative Services Energy Management group (DCAS Energy Management) is utilizing its purchase of renewable energy from an upstate New York wind farm to assist LL86 projects with earning LEED® renewable energy credits. All projects subject to the law, as well as related costs and benefits, are detailed in a series of annual reports published by MOEC.

Up-to-Date Information
The rules that implement LL86 are evaluated and amended periodically by MOEC to reflect the most current reference standards and advances affecting the green construction industry. To read the most up-to-date information, visit MOEC's Green Building website. DDC also offers LL86 related information on training, forms and examples and a timeline (in PDF) for LL86 projects managed by DDC.
