Green building is a phrase which refers to the implementation and use of environmentally-friendly practices and materials in the location, design, construction, operation and disposal of buildings and homes. This noble concept applies to both renovation and retrofitting of existing buildings and construction of new buildings, whether residential or commercial, public or private. The trend for creating greener buildings and structures is now viewed as an important instrument for positive change in the building industry.
