Why LEED Was Created?








Facilitate positive results for the environment, occupant health
and financial return
Define “Green” by providing a standard of measure
Use as a design guideline
Recognize leaders
Stimulate green competition
Establish market value with recognizable national “brand”
Raise consumer awareness
Transform the marketplace!

LEED - NC Certification Process
A three step process:


Step 1: Project registration
 Site selection and document registration with USGBC
Step 2: Construction phase
 Development of design criteria
Creation of LEED letter templates and required engineering
documentation
Step 3: Building Certification
 Building completion and submission to the USGBC for final
review
