生分解性建材とデジタルライフサイクル管理を統合した「バイオデジタル改修フレームワーク」を提案・検証した研究。菌糸体複合材の間仕切りとヘンプクリート断熱改修の2事例で、最大58%の内包炭素削減と高い循環性（MCI>0.8）を確認。AI支援意思決定とマテリアルパスポートが再利用・制御された生分解を可能にする一方、耐久性・認証・コストが導入課題として指摘された。
English
This study develops and validates a bio-digital building adaptation framework linking biodegradable materials with AI-enabled digital lifecycle tracking. Two scenarios—mycelium composite partitions and hempcrete insulation retrofits—achieved up to 58% embodied carbon reduction and high circularity (MCI >0.8). Digital material passports and AI decision support extend service life and enable reuse, though durability, certification, and cost remain adoption barriers.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
建設セクターのScope 3（建材調達・廃棄）削減と循環経済は、SSBJのサステナビリティ開示や有報での気候関連情報において重要性が増す領域。マテリアルパスポートやAI追跡は、日本企業が建材の内包炭素データを開示・検証する際の実務的基盤となりうる。
In the global GX context
As ISSB/CSRD push embodied-carbon and circularity disclosure into the built environment, this paper offers a concrete bio-digital framework for material passports and AI-tracked lifecycle data. It contributes to global disclosure scholarship by showing how circularity metrics (MCI) and digital tracking can be operationalized for adaptive reuse and retrofit reporting.

📄 Abstract（原文）
This study examines how circular economy principles in the built environment can be advanced by integrating biodegradable construction materials with digital lifecycle intelligence. It addresses the persistent challenges of embodied carbon reduction, waste minimisation and material recovery in building adaptation and retrofitting, aiming to develop and validate a bio-digital framework that enables regenerative material cycles. An exploratory mixed-method research design was adopted, combining a systematic literature review with the development of a circular economy-driven bio-digital adaptation framework. Two illustrative case scenarios modular partition systems using mycelium composites and ceiling insulation retrofits using hempcrete were analysed using life cycle assessment material circularity indicators, and AI-supported decision simulations. Framework validation was undertaken through a Delphi-lite expert workshop involving academic and industry stakeholders, providing quantitative ratings and qualitative feedback on feasibility, scalability and innovation. The results indicate that bio-digital systems can achieve substantial embodied carbon reductions (up to 58%) and high circularity performance (Material Circularity Indicator >0.8) compared with conventional alternatives. The scenarios demonstrate that biodegradable materials, when supported by digital tracking, material passports, and AI-enabled decision support, can extend service life, enable controlled biodegradation, and support reuse pathways. Expert feedback confirmed the framework's innovation and practical relevance, while identifying durability, certification, and cost as key adoption challenges. This study presents the first integrated bio-digital adaptation framework that explicitly links biodegradable materials with digital lifecycle intelligence. By treating biomaterials as actively managed resources rather than passive substitutions, the framework offers a novel pathway for embedding circular economy principles into adaptive reuse and sustainable retrofitting.
