本研究は、EPBD IV指令に対応したBIM-LCA統合ワークフローを開発し、保育園設計に適用。6つの材料シナリオを評価した結果、リサイクル材の使用でコスト増を抑えつつクラスB達成、床スラブ変更でクラスAを実現し、BIM-LCAが公共設計の脱炭素ツールとして有効であることを示した。
English
This study develops a BIM-LCA workflow for EPBD IV compliance, applied to a nursery school design. Evaluating six material scenarios, it finds that high recycled content achieves Class B with minimal cost increase, while an alternative floor slab enables Class A certification. The workflow is effective for sustainable public design.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
EPBD IVはEU指令だが、BIM-LCAによるエンボディードカーボン評価手法は、日本の建築物省エネ基準やZEH・LCCM住宅にも応用可能。日本の建設業界がグローバルな脱炭素規制に対応する上で参考となる実践的知見を提供する。
In the global GX context
As EPBD IV tightens embodied carbon requirements, this workflow provides a replicable method for compliance. It bridges the gap between BIM and LCA, addressing interoperability and data quality issues, and offers a cost-effective path to higher energy classes.

📄 Abstract（原文）
The construction industry plays a pivotal role in the decarbonization process and the transition toward circular economy models. Within a regulatory framework redefined by the EPBD IV Directive—which introduces Life Cycle Global Warming Potential (LC-GWP) as a mandatory indicator for new buildings—this study analyzes the integration of Building Information Modeling (BIM) and Life Cycle Assessment (LCA) to support design decisions aimed at reducing embodied carbon. Addressing challenges highlighted in the literature—such as platform interoperability, inconsistent Environmental Product Declaration (EPD) quality, and a scarcity of practical case studies—a BIM-LCA workflow was developed using Autodesk Revit and One Click LCA, supplemented by a cloud platform to account for elements not modeled in 3D. The method was applied to the design of a nursery school in the Municipality of Montoro, evaluating six material scenarios in terms of Global Warming Potential (stages A1–A3) and supply costs. The results demonstrate that using materials with high recycled content enables the achievement of Class B ratings with minimal cost increases, while an alternative floor slab system allows for Class A certification and superior environmental performance. The study confirms the effectiveness of the BIM-LCA approach as an operational tool for sustainable public design that complies with EPBD IV requirements.
