高温乾燥地域（リヤド、アブダビ、ドーハ）の住宅外皮設計を対象に、パレート最適化を用いて運用エネルギーと体化カーボンのトレードオフを評価した。窓壁比の低減が最もバランスの良い性能を示し、高ガラス構成はエネルギー需要と材料強度を増加させることを明らかにした。
English
This study evaluates envelope design strategies for hot-arid residential buildings using a Pareto-based multi-criteria framework integrating operational energy and embodied carbon. Reduced window-to-wall ratios consistently achieve balanced performance across Riyadh, Abu Dhabi, and Doha, while high-glazing designs increase both energy and material intensity.

📄 Abstract（原文）
Hot-arid residential buildings experience persistent cooling demand and increasing material intensity, yet most building-performance studies prioritize operational energy while insufficiently integrating life-cycle carbon and material sufficiency into envelope evaluation. This limits the ability to distinguish between performance gains achieved through passive design efficiency and those dependent on increased material input. This study investigates the interaction between material sufficiency, energy use, and life-cycle carbon in residential buildings across three representative hot-arid climates: Riyadh, Abu Dhabi, and Doha. A Pareto-informed multi-criteria evaluation framework was applied using a standardized mid-rise residential prototype to assess predefined envelope design strategies under consistent operational conditions. Dynamic energy simulations were conducted in DesignBuilder/EnergyPlus, while embodied carbon was quantified through a consistent material inventory approach. Baseline energy use intensity (EUI) values reached 64.98, 83.13, and 93.67 kWh/m²·year for Riyadh, Abu Dhabi, and Doha, respectively, reflecting increasing cooling demand from inland dry to humid coastal conditions. Envelope optimization reduced EUI to 47.33–72.40 kWh/m²·year, while embodied carbon ranged from 40,761.2 to 57,146.2 kgCO₂-eq per configuration. Reduced window-to-wall ratio strategies consistently achieved the most balanced performance across all climates, whereas high-glazing configurations increased energy demand, carbon emissions, and material intensity. The study operationalizes a sufficiency-oriented evaluation perspective that supports climate-responsive envelope decision-making by integrating operational and material performance within a unified comparative framework.
