In reference to Living Steel‘s 3^rd International Architecture Competition for Sustainable Housing, Glen Murcutt discusses his ideas surrounding the issue of sustainability. He emphasizes the strategies employed by the top contenders such as the planning of orientation, thermal performance, and human effort in addition to other variables involved in sustainable architecture. One particular method that Murcutt stresses is using materials that can dissolve back into the earth, citing earth walls as an excellent medium to build with and their inherent thermal mass qualities. Each team was invited to present their ideas in person, a variation from previous years which Murcutt believes led to the highest quality of work and diversity of the competition series.
