Adaptive Reuse of a Historic Building by Introducing New Functions: A Scenario Evaluation Based on Participatory MCA Applied to a Former Carthusian Monastery in Tuscany, Italy

The lack of financial resources and the constraints about interventions are threatening the survival of built heritage and the multiple benefits it can provide. In time, the role of building conservation has changed from preservation to being part of a sustainable strategy where adaptive reuse may allow to protect built heritage, while promoting it as a resource. This paper presents the results of a multicriteria analysis applied to the case study of Certosa di Pisa in Calci (Tuscany), a former Carthusian Monastery currently run as a publicly owned museum center. Based on information gathered from literature and the involvement of the two main stakeholders, a SWOT analysis was performed to identify three scenarios in which new functions were introduced with the aim to cover restoration and maintenance costs. Scenarios were compared by using a participatory MCA, taking into account not only economic performances but also cultural, territorial integration and restoration co-impacts. Results show that it is possible to reach economic sustainability while conserving heritage values, but several criticalities may hinder the process. Conclusions discuss the suitability of the method in identifying sustainable reuse solutions and highlight the role of governance bodies and the problems related to their public and/or private composition.
