Adaptive Reuse and Sustainability Protocols in Italy: Relationship with Circular Economy

This paper explores the enhancement of adaptive reuse (AR) of buildings through the lens of the sustainability protocols within the context of circular economy (CE) in Italy. Cities and the built environment can play a key role in the transition to a CE, especially considering the documented negative global impact due to resource consumption and waste generation. This is recognised among the principles of circularity defined by the European Commission towards a general strategy for a sustainable built environment, which encourages initiatives of building reuse and land consumption reduction. It has been proven that the AR of vacant buildings can bring environmental, social, and economic benefits towards an urban strategy based on CE principles by generating useful values to support innovative development dynamics. In this perspective, the sustainability protocols can be identified as useful tools to pursue strategies for spreading the culture of sustainable build environment. Considering the huge vacant Italian architectural heritage, this paper aims to analyze how the most widely used sustainability protocols in the Italian context currently address the enhancement of the reuse of buildings, to improve environmental, social, and economic quality in the built environment. We discuss the results highlighting how and which sustainability protocols better intercept these issues, providing grounds for future development.
