An Automated Linked Data Approach for Integrating a TGO Embodied Carbon Emissions Material Database with BIM Models

Abstract

The construction industry accounts for 40% of global energy consumption and greenhouse gases emission, emphasizing the need for sustainable solutions. This research proposes an automated BIM-based approach to optimize embodied carbon (EC) and material costs at the production stage (A1-A3) by incorporating low-carbon materials during the design phase. Using Dynamo scripts, it connects the Thailand Greenhouse Gas Management Organization materials database and costs with Revit models to quickly and accurately calculate the embodied carbon and cost values. A case study of a two-storey residential building was analyzed. The embodied carbon and cost values are significantly reduced from 309.47 kgCO<inf>2</inf>e/m² and 3929.81 THB/m² to 265.25 kgCO<inf>2</inf>e/m² and 3581.68 THB/m² resulting in a total reduction of 14.30% and 8.85% respectively. The results are visualized in Power BI to support environmentally conscious design decisions.
