LEED stands for Leadership in Energy and Environmental Design. They provide third-party certification of eco-friendly designs in schools, businesses, and other buildings. They were originally set up by the U.S. Green Building Council (USGBC) in 1993, in order to accomplish:
  • Define and measure what constitutes a green building
  • Stimulate competition in the green market
  • Heighten awareness of the benefits to a green building in consumers
  • Recognize innovators of environmental efficiency in the building industry
  • Promote designs of buildings that focus on every aspect
  • Change the building market

LEED uses eight major categories for determining a building's score:
  • Location and Planning
  • Sustainable Sites
  • Water Efficiency
  • Energy and Atmosphere
  • Materials and Resources
  • Indoor Environmental Quality
  • Innovation and Design Process
  • Regional Priority
