The question is: is weak and very weak sustainability going to deliver sufficient changes for the generations to come and those already here? Washington (2015) and Brown (1995) strongly assert this level of sustainability will fall far short of what is needed. The built environment is responsible for significant environmental impacts. Buildings use resources during construction with the extraction of resources, energy and water resources are used in the transport and manufacturing of construction materials and components. Vast amounts of waste are created at this stage. During the operational phase energy resources are used to light, heat and cool buildings, and water is used in building services. Materials used during construction affect occupant health. At the end of
