本研究はBIM、LCA、ライフサイクルコスティング、多基準意思決定（MCDM）を統合し、建設プロジェクトの炭素排出とコストを同時に最適化する枠組みを開発した。BIMから資材量を抽出し、炭素排出係数・コスト情報と統合して、 embodied carbon や運用炭素、初期コスト、ライフサイクルコスト等を評価する。MCDMにより代替案を系統的に比較し、炭素削減と経済性のバランスを取る解を特定する。感度分析で基準重みの変動に対する頑健性も検証し、計画・設計段階での低炭素建設意思決定を支援する。
English
This study develops an integrated carbon–cost optimization framework combining BIM, LCA, life cycle costing, and multi-criteria decision making (MCDM) for sustainable construction evaluation. BIM-extracted material quantities are linked with emission factors and cost data to quantify embodied and operational carbon alongside initial and life-cycle costs. MCDM systematically ranks alternatives balancing carbon reduction and economic performance, with sensitivity analysis testing robustness under varying criterion weights. The framework supports low-carbon material selection and cost management at the planning and design stages.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
建設業はScope 3排出の主要因であり、SSBJや有報でのScope 3開示対応が進む日本企業にとって、設計段階での炭素・コスト統合評価はサプライチェーン排出管理と投資家説明に直結する。BIM活用は国内の建設DX・GX政策とも整合し、実務的な脱炭素意思決定ツールとして参考になる。
In the global GX context
Construction is a major source of Scope 3 emissions, and this BIM-LCA-MCDM framework offers a practical method for integrating carbon and cost at the design stage, aligning with ISSB/CSRD disclosure expectations for embodied carbon and transition planning. It adds to global scholarship on decision-support tools for low-carbon construction and can inform TCFD-aligned scenario analysis in the built environment.

📄 Abstract（原文）
The construction industry faces increasing pressure to reduce carbon emissions while maintaining project affordability and long-term economic performance. This study develops an integrated carbon–cost optimization framework combining Building Information Modelling (BIM), Life Cycle Assessment (LCA), Life Cycle Costing (LCC), and Multi-Criteria Decision Making (MCDM) for sustainable construction project evaluation. BIM is used to extract material quantities and project data, which are integrated with carbon emission factors and cost information to quantify life-cycle environmental and economic impacts. Alternative construction scenarios are evaluated by considering embodied carbon, operational carbon, initial construction cost, life-cycle cost, energy performance, and other relevant project criteria. An MCDM approach is applied to systematically assess the alternatives and identify solutions that achieve an effective balance between carbon reduction and economic performance. Sensitivity analysis is further employed to examine the robustness of the decision-making outcomes under variations in criterion weights. The integrated framework provides a structured decision-support approach for comparing construction alternatives at the project planning and design stages. The study demonstrates how BIM-enabled environmental and economic assessment can support informed material selection, cost management, and low-carbon construction strategies. The research contributes to sustainable construction management by integrating carbon and cost considerations within a unified decision-making framework and provides practical support for project managers, cost professionals, designers, and other stakeholders pursuing economically viable low-carbon construction.
