In recent years, both the public concern on environmental issues and the interest and demand for sustainable buildings have been growing worldwide. Architects, engineers, building developers, and buildings owners are feeling pressure to design, construct, and maintain buildings that respect sustainability and the environment. In support of sustainable development initiatives of governments and the building industry, the Canadian Standards Association (CSA) has established a Technical Committee on Sustainable Buildings, which has been tasked to develop national standards to advance the design, construction, and maintenance of buildings in a sustainable manner. This paper first discusses the standards development environment in Canada and the standards development process in CSA and goes on to describe the development of a new standard on the design for disassembly and adaptability of buildings.
