What if we could evaluate projects, plans and designs using an enhanced concept of sustainability? “For sustainability to occur, it must occur simultaneously in each of its three dimensions” (economic, social and environmental) Larsen, 2012. These three crucial and necessary dimensions of sustainability are, each of them, connected to big traditions of study and analysis that must be integrated. My claim here is that this enhanced concept of sustainability help us derive solid criteria to evaluate plans, projects and designs in Urbanism, and to connect this evaluation to larger academic traditions.
