The built environment has a significant potential to reduce carbon emissions and raw material consumption. Digitisation processes such as Building Information Modelling (BIM) and Life Cycle Assessment (LCA) can offer solutions to improve sustainability throughout the building’s life cycle for the decarbonisation of the industry. In Ireland, the Royal Institute of Architects Ireland (RIAI) launched the 2030 Climate Challenge in response to the climate emergency. This sets out a list of targets to meet before 2030 for carbon emissions within the built environment. This research aims to investigate if the application of BIM tools can be leveraged to automate Global Warming Potential (GWP) to support design decision-making in meeting the RIAI 2030 Climate Challenge. This research focuses on the development of a validated database for building materials using the growing register of Environmental Product Data certificates (EPD) necessary for the correct calculation of GWP of building materials. This study has developed a series of workflows that can be used to automate and monitor Global Warming Potential (GWP) to assist professionals in meeting the RIAI 2025/2030 embodied carbon targets. The results demonstrated a proof of concept for automating GWP calculation via the digital building model database and, in doing so, giving the design team visual feedback, empowering them in their design decision-making.
