Research output: Chapter in Book/Report/Conference proceedingConference contribution


New retrofitting approaches, including off-site modular, are being developed with the aim of improving energy efficiency at the scale and speed needed to achieve net zero greenhouse emissions. Despite this, little attention has been paid to the supply chains emerging for innovative building retrofit. Using nine semi-structured interviews with stakeholders in two innovative off-site retrofitting projects, this research aims to address this gap. Through this, ‘trio’ and ‘powerhouse’ supply chain structures are identified, formed by three key stakeholders: the Housing Partner; the Intermediary and the Solution Provider. An interdependent four-stage communication is identified which is used for determining relevant sub-contractors and problem solving. The consistency of this pattern in both projects, despite different supply chain structures, indicates the importance of shared objectives among building professionals for successful retrofitting. This insight is valuable for policy makers looking to support innovative techniques for delivering large scale retrofitting schemes.
