The construction and maintenance of buildings are responsible for 40% of US energy use and 30% of wood and raw materials use (more on these statistics can be found at Global Green USA). Green or sustainable building is the practice of creating healthier and more resource-efficient models of construction, renovation, operation, maintenance, and demolition. Research and experience increasingly demonstrate that when buildings are designed and operated with their lifecycle impacts in mind, they can provide great environmental, economic, and social benefits.
