What is Green Building? Sustainable Building  • No net impact on the environment Green Building • Incremental steps to solve known problems using  current and emerging practices • Today’s  green building is typically not sustainable • Greener than baseline

World resources are finite….

No longer OK for us to be sustainable “over there” 

“Dad! Mom!  Please save  some for us!”

….. and we are depleting them at  accelerating & unsustainable rates

THE BAD NEWS: The Negative Impacts of Buildings on Environment

U.S DOE: buildings in the US:

Buildings account for:

• 5 billion gal/d of potable water used to flush toilets. • A typical commercial construction job creates ~2.5lb waste/ft2 floor space • Real estate development appropriates land from other uses such as natural habitats and agriculture.

• 49% of sulfur dioxide emissions • 25% of nitrous oxide emissions • 10% of particulate emissions • 35% of carbon dioxide emissions

Between 2002 and 2010, ~38 million buildings built worldwide.

Green Building Rating System

City in Central UK

A rating system for designing, constructing, operating and certifying green development.

Why Was LEEDTM Created?  Providing a standard

LEED Certification vs Accreditation

 Provide design guidelines &  Promote whole whole--building, integrated design processes

Certified

 Prevent “greenwashing “greenwashing”” (false/exaggerated

Buildings get CERTIFIED
