About LEED

LEED, or Leadership in Energy & Environmental Design, is recognized across the globe as the premier mark of achievement in green building.  To receive LEED certification, building projects satisfy prerequisites and earn credit points to achieve different levels of certification.  Prerequisites and credits differ for each rating system, and teams choose the best fit for their project.

LEED v4, introduced in 2013, focuses on five distinct rating systems:

LEED for Building Design and Construction (LEED BD+C) is for new building construction or major building renovations.
LEED for Interior Design and Construction (LEED ID+C) is for interior fit-outs.
LEED for Building Operations and Maintenance (LEED O+M) is for existing buildings that are undergoing little-to-no construction.
LEED for Neighborhood Development (LEED ND) is for land development projects or redevelopment projects.
LEED for Homes is for single family homes, low-rise multi-family (one to three stories), or mid-rise multi-family (four to six stories)

LEED certification is based on a 110-point scale, with prerequisites and credits organized into categories:

Location and transportation credits reward projects within relatively dense areas, near diverse uses, with access to a variety of transportation options, or on sites with development constraints.
Sustainable sites credits encourage strategies that minimize the impact on ecosystems and water resources.
Water efficiency credits promote smarter use of water, inside and out, to reduce potable water consumption
Energy and atmosphere credits promote better building energy performance through innovative strategies.
Indoor environmental quality credits promote better indoor air quality and access to daylight and views.
Innovation credits address sustainable building expertise as well as design measures not covered under the five LEED credit categories
Regional priority credits address regional environmental priorities for buildings in different geographic regions.
