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.
