Digital Twin Potentials: Decarbonisation Tool for the Built Environment Part 2 Dissertation 2022 Louise Weston Queen's University Belfast | UK Compelling solutions are required that will help to shrink the construction industry’s carbon footprint towards Net-Zero. Innovation and change are essential for a sustainable future. Currently, Digital Twins do not provide a solution to climate resilience, however, they promise to enable dynamic modelling and tools that allow architects, clients and users to predict and track lifecycle performance. For the full potential of this technology to be realised, many factors need to be advanced and questioned. This dissertation examines how the use of digital twins in smart cities is resulting in a more sustainable built environment through multidisciplinary collaboration; and what the resulting implications could be. The implementation of circular construction methods in the UK can be facilitated by using Digital Twins. The future usage of Digital Twins is critically assessed to understand what progress, investment, governance and operational change needs to happen in advance of assigning Digital Twins environmental tasks. The research is based around two interviews with experienced industry practitioners. The paper uses ‘Digital Twins’ as a model to test a net-zero approach to current construction methods within cities in the UK. This innovative research explores how Digital Twins could best be developed to help decarbonise the built environment. Tutor(s) Tom Jefferies
