A New Framework for Circular Refurbishment of Buildings to Operationalize Circular Economy Policies

The current policies aimed at promoting the decarbonization of existing buildings under the principles of the circular economy are in need of practical measures tailored to local conditions to increase their effectiveness. The lack of standard practices for assessing buildings' refurbishment strategies toward energy efficiency and CE principles reflects this reality. To tackle this issue, a new framework for refurbishing circular buildings, is proposed in this paper, based on circular procurement and incorporating a lifecycle perspective. This framework articulates a dialogue between local authorities and private stakeholders through a set of steps that encompass building mapping, selective disassembly, (re)design, and (re)build practices, providing opportunities to implement policy-based incentives. The application of the framework within the Portuguese context demonstrates the potential to identify critical moments within the refurbishment process that can materialize in a new set of CE policy actions to be implemented at the building level. These policies are aligned with local construction permitting procedures and take advantage of the resources and incentives offered by the local administration, such as tax incentives.
