本研究は、タイのTGOデータベースを活用し、Autodesk RevitとKit Carbonを統合した地域化BIM-LCAワークフローを構築した。チェンマイ大学の13階建て駐車場棟を事例に、構造部材のA1〜A3段階のembodied carbonを算定し、総量3,659.89 tonCO2e、原単位0.099 tonCO2e/m²を得た。上部構造と基礎が全体の83.90%を占めるホットスポットであることを示し、設計初期段階での地域データベース活用の有効性を実証した。

This study develops a localized BIM-integrated LCA workflow using Thailand's TGO database, linking Autodesk Revit with Kit Carbon for real-time embodied carbon assessment. Validated on a 13-story parking building at Chiang Mai University (modules A1-A3), it found 3,659.89 tonCO2e total and 0.099 tonCO2e/m² intensity, with superstructure and foundations accounting for 83.90% of emissions. It shows localized databases enable more accurate pre-construction design decisions than generic global tools.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では建設業のembodied carbon算定はScope 3カテゴリ1・2やSSBJ開示と連動しつつあり、地域データベース（IDEA等）とBIM連携の重要性が増している。タイのTGO活用事例は、アジア新興国での開示インフラ整備と日本企業の海外建設プロジェクトにおける炭素管理に示唆を与える。
In the global GX context
As ISSB/CSRD push Scope 3 and embodied carbon disclosure, this paper shows how localized LCA databases integrated with BIM can overcome the inaccuracy of generic global tools. It offers a replicable model for emerging markets and for multinational construction firms needing region-specific carbon accounting.

📄 Abstract（原文）
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 Embodied Carbon (EC) during the early design stages is critical for mitigating climate change and aligning with Sustainable Development Goal 13. However, while global Building Information Modeling (BIM), tools for sustainability exist, they often rely on generic international databases. This limitation leads to significant discrepancies when quantifying emissions in specific regions like Thailand due to variations in material production and supply chains. This study addresses this gap by implementing a localized BIM-integrated Life Cycle Assessment (LCA), workflow. The framework integrates Autodesk Revit with Kit Carbon software to utilize the Thailand Greenhouse Gas Management Organization (TGO) database for real-time Embodied Carbon (EC) assessment. The workflow was validated through a case study of a 13-story parking building project at Chiang Mai University, focusing on the product stage, specifically modules A1 through A3, of the structural components. The results revealed a total Embodied Carbon (EC) of 3,659.89 tonCO2e, translating to an Embodied Carbon Intensity (ECI) of 0.099 tonCO2e/m². Furthermore, the superstructure floors and substructure structural foundations were identified as the primary carbon hotspots, collectively accounting for 83.90% of the total structural emissions. Ultimately, this study demonstrates that utilizing a localized database within a Building Information Modeling (BIM) environment provides designers with a more accurate and reliable framework for decision-making and structural optimization in the pre-construction phase, overcoming the limitations of non-localized global tools.
