An Integrated Framework to Support Adaptive Reuse Urban Design: a Case Study in the City of Taranto (Italy)

The phenomenon of commercial structures facing decommissioning is a significant challenge across European territories, with Italy witnessing a surge in such closures. These structures are often temporarily reopened without strategic foresight, creating a need for long-term, sustainable redevelopment plans. This paper addresses the urgent requirement for an integrated and mixed approach to guide the decision-making process in the urban transformation of Taranto, Southern Italy. The proposed redevelopment strategy pivots around the renovation of a local shopping center, aiming to revitalize the surrounding area. The project’s objectives include enhancing site accessibility, introducing new services, and promoting tourism in anticipation of the Mediterranean Games scheduled for 2026 in Taranto. The redevelopment leverages an assortment of evaluation models, embracing various approaches and scales. Initial stakeholder and STEEP analysis laid the groundwork for presenting four distinct visions for the area, which were critically assessed using the PROMETHEE II decision-making tool. The most viable option was further examined through discounted cash flow analysis (DCFA) for financial feasibility and a cost-effectiveness analysis (CEA) to gauge environmental sustainability. The comprehensive evaluation model integrates urban design with economic, social, and environmental criteria, providing a holistic framework for transformation. By aligning with circular economy principles, the approach promotes adaptive reuse of existing structures, conservation of natural resources, the implementation of Nature-Based Solutions (NBS), and social inclusivity. This strategy enriches both the built and natural environments, fostering a resilient and sustainable urban community.
