本研究は、カメルーンにおいて現地調達材料を用いた持続可能な孤児院設計にBIMを適用。圧縮土ブロック（CEB）はサンドクリートブロックと比較して建設コスト、体化炭素、熱的快適性で優れることを示し、地域に検証されたデータセットと再現可能なデジタル設計フレームワークを提供する。
English
This study applies BIM to design sustainable orphanages in Cameroon using locally sourced materials like compressed earth blocks (CEBs). Through comparative analysis, CEBs showed lower construction costs, reduced embodied carbon, and improved thermal comfort over sandcrete blocks. It provides the first regionally validated dataset and a replicable digital framework for sustainable humanitarian architecture in Sub-Saharan Africa.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
カメルーンにおける現地調達材料とBIMの活用は、日本の建設業界でも関心が高いテーマである。特にSSBJ対応の観点から、ライフサイクルアセスメント（LCA）や建材の環境性能データは重要であり、本論文の手法は日本のゼロエネルギー建築やサプライチェーン排出削減に示唆を与える。
In the global GX context
This study contributes to the global discussion on sustainable construction and lifecycle assessment in low-resource settings. For countries addressing climate resilience in building codes and infrastructure, the BIM-LCA integration and empirical performance data for compressed earth blocks are valuable for evidence-based material selection and emissions reduction strategies.
👥 読者別の含意

📄 Abstract（原文）
In Sub-Saharan Africa, and particularly Cameroon, the demand for socially inclusive and environmentally responsible architecture is growing due to rapid urbanisation, climate pressures, and the needs of vulnerable communities. Orphanages, as critical social infrastructure, are frequently delivered through cost-driven approaches that neglect sustainability and long-term performance. While Building Information Modelling (BIM) has globally advanced design precision, cost optimisation, and environmental performance analysis, its application in Africa especially for projects using eco-friendly materials such as compressed earth blocks (CEBs) remains limited. This study employs BIM, through Autodesk Revit, to design sustainable, child-centred orphanages in Cameroon using locally sourced materials. Two functionally equivalent prototypes, one with sandcrete blocks and another with CEBs, were developed and evaluated through comparative cost estimation, embodied carbon and energy analysis, and operational performance assessment, in line with life-cycle assessment (LCA) standards and thermal comfort benchmarks. Results show that CEBs delivered lower construction costs, reduced embodied impacts, and improved thermal comfort compared to sandcrete. BIM-enabled workflows enhanced quantity take-offs, integrated early LCA, and supported evidence-based material selection. This research provides one of the first regionally validated datasets on sandcrete and CEB performance in Cameroon, while proposing a replicable digital design framework for humanitarian architecture in resource-constrained Sub-Saharan contexts.
