A social network perspective on mapping supply chains for building retrofit

28 April 2023

Wide-scale building retrofit is necessary for achieving reductions in energy demand and creating healthier homes. Despite this, policy and industry strategies are still failing to deliver retrofit at the speed and scale necessary to achieve climate targets. Strategies for wide-scale energy retrofitting include developing local traditional supply chains, and introducing whole house techniques. These involve very different supply chain actors and skills, with implications for retrofit success and realised energy demand deductions.

However, policy makers do not yet have a firm grasp on the differences in these retrofitting supply chains, or how they can be scaled up to deliver retrofitting at the rate needed. This project fills this gap by using Social Network Analysis (SNA) to map the communication networks of supply chain actors recruited into the two types of project conducted in one UK case study. This talk mainly highlights the research design process of this project, with an intention to provide an overview of social network theory and how SNA as an emerging and powerful tool can be applied in construction management areas.

  • Speaker: Dr Yujia Han is a Research Fellow at the School of Social and Political Science from the University of Edinburgh. She joined Centre for Research into Energy Demand Solutions (CREDS) to undertake research project with Faye Wade under the theme of ‘Policy and Governance’. Yujia’s primary research area is buyer-supplier relationship in the context of complex infrastructure project supply chains. She is particularly interested in exploring how social network theory contributes to non-linear, non-successive relationships in supply networks. Prior to her PhD studies at Heriot-Watt University, Yujia worked as a senior buyer in the oil and gas industry. She holds a BSc degree in Electrical Engineering from Northeast Electric Power University and an MSc in logistics and supply chain management from Heriot-Watt University.
