LEED – Developed by USGBCUS Green Building Council

LEADERSHIP inENERGY andENVIRONMENTALDESIGN

A leading-edge system for certifyingDESIGN, CONSTRUCTION, & OPERATIONSof green buildings

Scores are tallied for different aspects of efficiency and design in appropriate categories:

1. Site Planning2. Water Management3. Energy Management4. Material Use5. Indoor Environmental Air Quality6. Innovation & Design Process

Test

Levels of LEED Ratings

Green Buildings worldwide are certified with a voluntary,consensus-based rating system. USGBC has four levels of LEED.
