サーモクロミック調光ガラスを中国5気候区のオフィスビルに適用し、EnergyPlusと実測検証で220ケースを解析した。25℃の転移温度で温暖2区は2.76〜4.04%の負荷削減、Low-E複合構成では最大12.93%削減を達成。RF-SHAPにより削減率への影響度はガラス構成＞気候区＞方位＞転移温度の順と判明し、気候区別の選定枠組みを提示した。
English
Thermochromic glazing was modeled in EnergyPlus (validated against Chongqing field data) across China's five climate zones for office buildings. A 25°C transition temperature saves 2.76–4.04% of total loads in warm zones, while Low-E composite configurations reach up to 12.93%. RF-SHAP ranks glazing configuration above climate zone, orientation, and transition temperature, yielding a climate-zone-based selection framework for sustainable envelopes.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX文脈では、ZEB・省エネ法・建築物省エネ法対応や改修投資の判断材料として参考になる。ただし気候区・ガラス仕様は中国前提のため、日本での適用には国内気候・コスト条件での再検証が必要。
In the global GX context
Adds empirical, climate-zone-specific evidence to the global building-decarbonization literature, complementing EU EPBD and green-building certification debates. The RF-SHAP factor ranking offers a transferable methodology for envelope design guidance in other jurisdictions.

📄 Abstract（原文）
Buildings account for a substantial share of global energy use and carbon emissions, making climate-adaptive building envelopes critical for sustainable urban development. Thermochromic glazing dynamically modulates solar transmittance with temperature, offering a promising pathway toward sustainable buildings; however, guidance on transition temperatures and composite configurations across China’s five climate zones remains limited. This study therefore derives an evidence-based, climate-adaptive design strategy for thermochromic hydrogel-based insulating glass units in office buildings across these climate zones. To achieve this aim, an EnergyPlus model validated against summer field measurements in Chongqing quantified heating and cooling loads for 220 simulated cases and identified suitable glazing configurations and transition temperature, while RF-SHAP ranked factor importance. The results provide climate- and orientation-specific guidance for office-glazing selection: a 25 °C transition temperature delivers 2.76–4.04% total load savings in the two warm zones, and surface-2/3 Low-E composite TSG achieves up to 12.93%. In cold and severe cold zones, south-facing use can raise loads, whereas west-, east-, and north-facing applications retain saving potential; in temperate climates, single-silver Low-E glass is generally preferable. The RF-SHAP analysis ranks the factors influencing the total energy saving rate as glazing configuration > climate zone > orientation > transition temperature. These findings translate into a practical climate zone-based selection framework that supports sustainable building envelope design and retrofitting, helping to reduce operational energy consumption and carbon emissions while maintaining indoor thermal comfort.
