LEED™ or Leadership in Energy and Environmental Design is a leading edge system for designing, constructing, operating, and certifying the world's greenest buildings.

LEED™ is a rating system developed by the U.S. Green Building Council (USGBC) that certifies whether a building meets established targets for reduced environmental impact (sustainability). To achieve certifications, a building must meet seven prerequisites and earn a minimum number of points.

LEED™ was created to:

• define "green building" by establishing a common standard of measurement

• promote integrated design

• recognize environmental leadership in the building industry

• stimulate competition among design professionals as well as building owners

• raise consumer awareness of the benefits of green building

• transform the building mark
