Though there are varying definitions of this term, it is generally accepted that Green Building is the practice of creating buildings that are designed, built, renovated, operated, or reused in an ecological and resource-efficient manner. Green building, also known as sustainable building, can include the practices of salvaging material from building demolition for reuse in new buildings and for recycling. The term green building is also applied to buildings that minimize impact to the environment, protect health and enhance productivity of occupants, and utilize energy, water, and other resources efficiently. Usually, this is in terms relative to that of traditional building construction practices, as there is no universally accepted standard for what is considered “green” and what isn’t.
