Circular Processes and Life Cycle Design for Sustainable Buildings

The paper presents some research paths that the authors have deepened with the aim of orienting the building sector towards sustainability. In particular, the need to apply a systemic vision emerges, going beyond the single-issue approach often adopted by the political framework too. A life cycle approach, that considers the whole life cycle phases, the different environmental indicators, and the various spheres of sustainability (environmental, economic and social), can support strategies and decisions to ensure long-term sustainability. Three courses of action are highlighted: the development of environmental life cycle tools, to support the decision-making during the design phase (but also of the following building process phases); the development of circular strategies, with reference to the changes needed along the entire supply chain (involving design, business models, resource management); the development of reversible technologies, to improve resource efficiency and circularity (e.g. through design for disassembly). Finally, some key issues are outlined for future developments.
