A sustainable building is one that is built, renovated or reused in an ecological manner. They meet certain objectives, such as using energy, water, or other resources efficiently. In general they reduce the overall impact to the environment.
Part of the practice of sustainable or green building construction is the recycling and reuse of construction and demolition debris. This includes salvaging of among other things lumber, concrete, wallboard, carpet, shingles and more.
Construction waste also would include corrugated cardboard (used in packaging), plastics including PVC pipe and packaging, glass and site work waste.
Green Building considers energy efficiency, materials efficiency, water efficiency, occupant health and safety, as well as building operation and maintenance.
When considering a green building project develop a clear statement as to the vision, design, priorities and goals of your project. Be sure to consider green building measures and allocate for contingencies in your project budget. Set a project schedule that allows for testing and commissioning and create effective incentives and oversight.
Above all do your research and seek the advice of professionals with experience in this field that are committed to your vision.
