The Polytechnic University of Madrid has designed an industrialized prototype of a single family house, to participate in the Solar Decathlon 2007 Contest. The design objective was the complete energy self-sufficiency in the annual cycle, and become a research platform for the optimization of this objective. Inside the research lines for the optimization of the prototype there is the one that studies the sustainable materials of the house. We have studied the enclosures of the SD07 prototype to improve the choice of each material involved. The design of the prototype SD0 7 used materials from renewable sources (vegetable fiber panels, OSB), recyclable materials (cold-formed steel), recycled materials (almond shell panels), and material that can be reusable (rolled steel sections, insulation panels, wood panels, floors). We have carried out a simplified assessment of the sustainable conditions of materials used in multilayer prototype SD07 enclosures. We noted, that overall, the level of sustainability of materials used in the prototype SD07 allows us to improve the characteristics of the sustainable design. We have found the main goal for the development of the sustainability that can incorporate aspects for healthier and more respectful conditions for people and the environment
