Rating system as design tool to manage complexity

During the last decades the way we have managed the built environment has deeply changed. New factors of indeterminacy and unpredictability have been introduced due to the economic and environmental crisis, and the harshening of particular social issues. Thus, new designing approaches have become necessary. In this framework, sustainability building Rating Systems (RS) have gradually spread as design tools. In some cases, they specifically incorporate principles of resilience to cope with criticalities of the built environment, both acute and chronic. On this basis, the paper proposes the formulation of a RS to increase the resilience of industrial sites, a key asset in the management of territory. Hence, the project becomes an open protocol, flexible and adaptable on a case-by-case basis.
