The city of Palma is currently testing the approach through pilot large-scale retrofitting actions for multi-family residential buildings using a novel Public Private Partnership mechanism. The process combines technical assistance, financing support, and citizen engagement activities to facilitate implementation. Several tools and methodologies developed within the project support the identification of priority buildings, assessment of retrofit scenarios, and evaluation of district-level impacts. These tools provide opportunities for scaling the approach to additional neighbourhoods and municipalities facing similar renovation challenges. The solution demonstrates how municipalities can act as facilitators of large-scale residential renovation by combining public funding opportunities, technical expertise, and private sector participation within a coordinated implementation framework.
