What is LEED for Existing Buildings?

The impression in the marketplace is that LEED is only for new construction, which is not correct! LEED for Existing Buildings was developed by the U.S. Green Building Council to provide the existing building stock with an entry point into the LEED certification process.

LEED EB certification recognizes actual building performance rather than design. Properly implemented, EB can reduce operating costs and promote a healthy, productive indoor environment. EB measures the areas of water and energy efficiency, use of environmentally friendly cleaning products, indoor environmental quality, and the effectiveness of recycling programs among others.
