Balancing Cultural Values and Energy Transition: A Multi-Criteria Approach Inspired by the New European Bauhaus

The energy efficiency of historic buildings is the focus of activities aimed at developing replicable methodologies for implementing innovative technological solutions. In line with this priority, the Sicilian Region has launched a project for the energy retrofitting of 91 her- itage sites and buildings across the region. To support the decision-making process, this paper defines criteria and indicators for assessing the compatibility and effectiveness of energy efficiency upgrade solutions for buildings of cultural value. The goal of improving energy performance is framed within broader performance targets, including enhancing user experience, promoting cultural activities for users’ creative growth, and carrying out restoration works to strengthen the identity of the pre-existence. The criteria result from a thorough analysis of the current scientific debate on the energy efficiency of her- itage buildings and have been validated through their application to the case study of Palazzo Belmonte-Riso, a listed building in the historical centre of Palermo (Italy). The suggested criteria provide guidance for evaluating implemented projects and developing new design solutions. The research proposes a holistic and multidisciplinary approach aligned with the New European Bauhaus, promoting creative and innovative solutions that embody sustainability, aesthetics, and inclusiveness in addressing key issues on the European Agenda.
