About LEED

LEED is the leading voluntary green building rating system in use today. It is developed and administered by the US Green Building Council (www.usgbc.org), a member-based non-profit organization.

LEED evolves with time. The version of LEED that is most commonly used today is LEED 2009 (also known as LEEDv3). The most recent version of LEED is LEEDv4 and was launched in the fall of 2013. Its use is currently voluntary:  until the summer of 2015, projects may choose to pursue LEED 2009 or LEEDv4. After that, all new LEED projects will have to register under LEEDv4. 

LEED rating systems are organized into a number of broad environmental categories:

LEED 2009

  •             Sustainable Sites (SS)
  •             Water Efficiency (WE)
  •             Energy and Atmosphere (EA)
  •             Materials and Resources (MR)
  •             Indoor Environmental Quality (EQ)
  •             Innovation in Design (ID)

 

LEEDv4

  •             Integrative Process (IP)
  •             Location & Transportation (LT)
  •             Sustainable Sites (SS)
  •                   Water Efficiency (WE)
  •             Energy and Atmosphere (EA)
  •             Materials and Resources (MR)
  •             Indoor Environmental Quality (EQ)
  •                   Regional Priority (RP)
  •             Innovation 


These categories are further subdivided into Prerequisites and Credits that cover a particular green measure that fits in the broad category. Prerequisites must be fulfilled in order for a building to achieve a LEED rating. Credits are associated with one or more points. Each Credit is identified by the letters that are abbreviations of the category it fits in and a number. For example, Sustainable Site Credit 3 in LEED 2009 is for Brownfield Redevelopment and is identified as SSc3, and Materials and Resources Credit 7 is for Certified Wood and is abbreviated MRc7.

There are four different levels of achievement under LEED: from lowest to highest, Certified, Silver, Gold and Platinum. These levels are attained by earning successively higher numbers of points (and, of course, by satisfying all prerequisites). The number of points you need to earn to achieve a given level varies according to the rating system, but Platinum is much more difficult to achieve than Certified.
