本研究は、フランスの4つの代表的な気候地域において、多層壁に組み込まれたバイオベースPCMのエネルギー、エクセルギー、経済性を系統的に評価した。PCMの厚さ、融点、配置の影響を調べたところ、厚さが最も支配的であり、すべての都市で厚さ5cm、融点28°C、レンガ-石膏境界面がバランスの取れた構成であることが示された。
English
This study systematically evaluates the energy, exergy, and economic performance of bio-based PCM integrated into multilayer walls across four French climates. A full factorial analysis shows that PCM thickness is dominant, and a balanced configuration (5 cm thickness, 28°C melting point, at brick-plaster interface) is consistent across all climates, emphasizing the need for multi-criteria evaluation.

📄 Abstract（原文）
• A parametric study evaluates PCM-integrated walls across four distinct climates. • Energy, exergy, and economic indicators reveal non-equivalent performance trends. • PCM thickness requires a balance between energy saving and economic return. • Exergy performance varies strongly with climate and differs from energy results. • Optimal PCM peak melting temperature is specific rather than universal. The increasing energy demand of the building sector, together with climate change mitigation and energy transition requirements, highlights the need for effective energy management strategies. Phase change materials (PCMs) integrated into building envelopes, particularly multilayer wall systems, have shown strong potential for reducing cooling related heat gain and improving thermal regulation. However, the performance of PCM-integrated multilayer walls has largely been evaluated from an energy perspective, with limited attention to thermodynamic efficiency and economic viability. In this study, the energy, exergy, and economic performance of a sustainable bio-based PCM integrated into multilayer wall systems is systematically evaluated under four representative French climates. A full factorial analysis is conducted to examine the effects of PCM thickness, melting temperature, and placement within the wall. The results show that PCM thickness is the dominant parameter affecting thermal performance, whereas the preferred configuration varies with climate and decision priority. No single configuration simultaneously optimizes energy saving, exergy efficiency, and economic return. However, the balanced configuration remains the same across all four cities, corresponding to a PCM thickness of 5 cm, a peak melting temperature of 28 °C, and placement at the brick–plaster interface. Overall, the study provides climate sensitive design guidance and highlights the importance of multi-criteria evaluation for PCM wall design.
