BIM-Based Life Cycle Assessment of the Embodied Carbon of High-Rise Building Construction Project

The construction industry is a major contributor to global greenhouse gas (GHG) emissions, with Embodied Carbon (EC) in building materials being a significant factor. Reducing EC during the early design stages is critical for mitigating climate change, aligning with Sustainable Development Goal (SDG) 13. While Building Information Modeling (BIM) presents a powerful platform for sustainable design, designers often lack accessible tools for real-time EC assessment using localized databases. This study addresses this gap by developing a system that integrates Autodesk Revit with Kit Carbon software to quantify and visualize the EC of structural components. The system was applied to a 13-story parking building construction project at Chiang Mai University. The assessment focused on the product stage (A1-A3) using a localized Thai LCA database (TGO). The results revealed a total Embodied Carbon of 3,659.88 tonCO₂e, equivalent to approximately 0.099 tonCO₂e/m², with superstructure floors and substructure foundations identified as the most carbon-intensive components. This proposed workflow provides designers with an effective, accessible tool for informed decision-making and structural optimization during the pre-construction phase.
