A residential or commercial structure that is built in a manner that promotes
energy conservation, uses environmentally friendly construction products in an
efficient way, and creates a healthy place to live or work. Examples of green
building techniques and processes include the use of geothermal heat pumps,
rainwater collection, and radiant ceilings. Many of these technologies can be
used for new or existing properties. The Leadership in Energy and Environmental
Design (LEED) Green Building Rating System establishes criteria for "green
buildings" in the construction industry.
