What is a GREEN BUILDING?



Green Building Occupants Are Healthier & More

Productive



Buildings are the single largest

contributor to global warming,

accounting for almost half of total

annual U.S. energy consumption

and CO2 emissions.

- U.S. Energy Information Administration



Impacts of U.S. Buildings on Resources

41% primary energy use

73% electricity consumption

38% CO2 emissions

17% potable water consumption



“Green buildings have been shown to

save money through reduced energy

and water use and lower long-term

operations and maintenance costs.”

- Business Case for Green Building (2013)
