OVERVIEW

The LEED Rating Systems make up a voluntary program meant to objectively measure how sustainable a building is in several key areas:

  • impact on site and location

  • water efficiency

  • energy efficiency

  • material selection

  • indoor environmental quality

The system also encourages innovation.

The LEED standards are maintained by the U.S. Green Building Council (USGBC), a nonprofit, non-governmental, membership-based organization. While participation in LEED is voluntary, the program owes some of its growth to municipal and state ordinances that have mandated it for public buildings and have offered incentives for private buildings.
