Net-Zero and Digitalisation in Off-Site Construction

The UK Government set targets to achieve net-zero buildings by 2050. Consequently, there is a need for off-site construction companies to achieve net-zero over the coming years. However, small and medium-sized enterprises in off-site construction face challenges in implementing net-zero, as well as in implementing digitalisation, which can greatly support achieving net-zero targets. This paper reports on initial findings of a project focused on improving digitalisation and net-zero within an SME off-site construction company. Through process mapping and observations, implementation barriers to digitalisation and net-zero were identified, and a set of actions are suggested. The paper also discusses tools for optimising the lifecycle carbon impact of buildings. The recommendations include accurate carbon footprint measurement, creating a realistic reduction strategy, and adopting sustainable/low-carbon materials. Additionally, the paper recommends the use of smart technology to monitor as-built and compare it with the as-designed building.
