本研究は、災害後の学校改修において、BIMとLCAを統合した意思決定支援フレームワークを提案する。シリア・ダマスカスの学校を対象に、浅層・先進・深層の3改修シナリオを、将来気候シナリオ（RCP2.6/4.5/8.5、2030/2050/2080年）の下で評価した。深層改修はPV統合によりネット・ポジティブエネルギーとネット・マイナス炭素を達成し、先進改修はMAC £0.89/kgCO2eで最も経済的に有利であった。RCP8.5の2080年には冷房需要が最大82%増加し、気候適応型の長期レジリエンス計画の必要性を示す。
English
This study proposes a BIM–LCA decision-support framework for prioritising school retrofit strategies in post-disaster contexts. Using a school in Damascus, Syria, it evaluates shallow, advanced (EnerPHit), and deep (EnerPHit+PV) retrofits under future climate scenarios (RCP2.6/4.5/8.5 for 2030/2050/2080). Deep retrofit achieves net-positive energy (+27.15 MWh/yr) and net-negative operational carbon (−14,428 kgCO2e), while advanced retrofit is most cost-effective (MAC £0.89/kgCO2e). Under RCP8.5 by 2080, cooling demand rises up to 82%, highlighting the need for climate-adaptive, scenario-aware planning.

日本のGX文脈において
日本では災害後の学校再建が頻繁に課題となるが、本フレームワークは気候変動下での長期レジリエンスと炭素評価を統合する点で、自治体や文部科学省の施設整備計画に示唆を与える。ただし、シリアの気候・制度条件に基づくため、日本への直接適用には注意が必要。
In the global GX context
While the case study is Syria-specific, the BIM–LCA framework integrating future climate projections and marginal abatement costs offers a transferable methodology for post-disaster reconstruction globally. It aligns with the growing emphasis on climate-resilient infrastructure and lifecycle carbon accounting in disclosure frameworks like TCFD and ISSB, though it does not directly address corporate disclosure.

📄 Abstract（原文）
Post-disaster reconstruction of educational facilities is frequently driven by heuristic decision-making that prioritises speed over long-term sustainability, resilience or climate compatibility. To address this gap, this study proposes a BIM-LCA decision-support framework for the evaluation and prioritisation of school retrofit strategies in post-disaster contexts. The framework integrates a BIM-derived building energy model with life cycle assessment based on EN 15978-compliant material take-offs and explicitly accounts for future climate projections. A two-storey school building in Damascus, Syria, classified under the Köppen-Geiger hot semi-arid climate zone, serves as the case study. Three retrofit scenarios are systematically evaluated against the status quo, namely shallow retrofit (external painting and shading), advanced retrofit (compliant with Passivhaus EnerPHit hot-climate standards) and deep retrofit (EnerPHit with photovoltaic integration). Simulations conducted in DesignBuilder v7 (DesignBuilder Software Ltd., Stroud, UK) assess three performance dimensions including operational and embodied energy, operational and embodied carbon footprint, and financial metrics including Net Present Value (NPV) and Marginal Abatement Cost (MAC). Future climate conditions for horizons 2030, 2050, and 2080 are generated using Meteonorm v8 (Meteotest AG, Bern, Switzerland) software under Representative Concentration Pathways RCP 2.6, RCP 4.5, and RCP 8.5. Results under the deep retrofit, on-site photovoltaic generation delivers net-positive energy performance, with an annual surplus of 27.15 MWh and net-negative operational carbon of −14,428 kgCO2e. The advanced retrofit realises a 32% decline in operational energy consumption at a MAC of £0.89/kgCO2e, rendering it the most favourable financial strategy under stable inflation-adjusted energy prices. Sensitivity analysis shows this ranking inverts towards the deep retrofit under sustained energy-price growth, and towards the shallow retrofit under a high cost of capital. Under RCP8.5 by 2080, cooling demand rises by up to 82% in the advanced and deep retrofits relative to their respective present-day values. The shallow retrofit records the lowest cooling demand among the retrofit options but remains approximately 9% above the contemporaneous status quo. These findings underscore the necessity of climate-adaptive, scenario-aware decision frameworks for post-disaster reconstruction, moving beyond static energy optimisation toward long-term resilience planning.
