📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本の建設業界では、SSBJ基準に基づくScope 3排出量の算定が進んでいるが、体化炭素の評価ツールはまだ普及していない。本システムは設計段階での簡易評価を可能にし、日本の施工会社や設計事務所にとって実務上有用である。

In the global GX context

Globally, embodied carbon accounting is gaining attention under frameworks like the EU's Level(s) and the UK's RICS standard. This BIM-LCA tool offers a practical approach for early-stage assessment, helping firms comply with evolving disclosure requirements.

👥 読者別の含意

🔬研究者:The paper provides a validated methodology for BIM-LCA integration that can be extended to other building types and regions.

🏢実務担当者:Designers can use this system to get real-time embodied carbon feedback during pre-construction, aiding material selection and design optimization.

🏛政策担当者:The tool could support building code development for embodied carbon limits, as it offers reliable early-stage estimates.

📄 Abstract（原文）

The construction industry significantly contributes to global greenhouse gas (GHG) emissions, particularly through the Embodied Carbon (EC) of building materials. Reducing EC during early design stages is critical for climate change mitigation. However, designers often lack accessible tools for real-time assessment. This study addresses this gap by developing a system that integrates Building Information Modeling (BIM) with Life Cycle Assessment (LCA) tools to quantify and visualize EC. The system was validated using a 13-story parking building project at Chiang Mai University. Results indicate that the BIM-based system’s calculations closely align with traditional methods, showing a deviation of only 0.8%. This demonstrates the system’s potential as an effective decision-making tool for sustainable design during the pre-construction phase. To validate the proposed system, this study compares the Embodied Carbon (EC) from the traditional method and the proposed system. The result shows that the Embodied Carbon (EC) from the traditional method was 4,299,207.03 kgCO2e and BIM-based Life Cycle Assessment (LCA) software was 4,265,126.28 kgCO2e, while the Percentage Difference from traditional method are more than the BIM-based Life Cycle Assessment (LCA) software 0.8%. Therefore, the proposed system is an effective tool to support informed decision-making for designers, allowing them to understand complex information more effectively during the pre-construction phases.
