Leadership in Energy and Environmental Design

• LEED is a green building certification process
  requiring project management to perform mandatory
  pre-requisites and a minimum number of credits
  (26) toward certification.
• To obtain certification, you must perform all the
  required pre-requisites, and can obtain anywhere
  from a minimum of 26 to a maximum of 69 credit
  points.
