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….

“Dad! Mom! Please save some for us!”

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

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

THE BAD NEWS: The Negative Impacts of Buildings on Environment

U.S DOE: buildings in the US:

• 5 billion gal/d of potable water used to flush toilets.

• A typical commercial construction• 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.

THE BAD NEWS: The Negative Impacts of Buildings on Environment

Buildings account for:

• 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.
