本研究は、建設材料の環境パフォーマンスを評価するために包括的なライフサイクルアセスメント（LCA）フレームワークを適用し、循環設計と再生可能エネルギーの統合による炭素排出削減戦略を調査した。結果として、中期的な環境影響は従来報告より20～30%高く、従来のレンガの地球温暖化係数は追加段階を考慮すると約23%増加することが明らかになった。地域固有のデータベースと循環型建設の促進が重要である。
English
This study applies a comprehensive LCA framework to evaluate the environmental performance of construction materials and investigate strategies for integrating circular design and renewable energy to reduce carbon footprints. Results show medium-term impacts are 20-30% higher than previously reported, and the global warming potential of conventional brick increases by about 23% when additional life-cycle stages are considered. Developing harmonized regional material databases and promoting circular construction are essential.

📄 Abstract（原文）
The construction sector is a major contributor to resource depletion and greenhouse gas emissions, underscoring the importance of adopting sustainable practices to meet environmental and climate goals. However, current assessments often underestimate impacts because of narrow system boundaries and insufficiently localized material inventory data, creating a critical research gap in accurately evaluating building sustainability. This study therefore applies to a comprehensive Life Cycle Assessment (LCA) framework to evaluate the environmental performance of key construction materials and to investigate strategies for integrating circular design and renewable energy to reduce carbon footprints. The results reveal that medium-term environmental impacts are approximately 20–30% higher than previously reported, while the Global Warming Potential of conventional brick increases by about 23% when additional life-cycle stages are considered. Furthermore, the analysis demonstrates that design-for-disassembly and recycling-oriented approaches can significantly enhance material recovery and reduce waste. These findings imply that developing harmonized, region-specific material databases and promoting circular construction alongside renewable energy integration are essential for improving LCA accuracy and achieving meaningful reductions in the environmental footprint of buildings.
