摘要

针对极端热浪叠加停电导致建筑主动热调节失效及室内过热风险的严峻问题，本工作提出了一种基于相变储热围护结构的建筑本体热韧性提升方法。以典型小型办公建筑为对象，基于EnergyPlus平台构建了集成CaCl

·6H

O/EG复合相变材料(PCM)的建筑热工模型。研究采用SSP5-8.5未来气候情景下的极端热浪数据，模拟停电工况下室内热环境的动态响应特征，并构建了包含室内过热度(IOD)、过热因子(OEF)及创新性指标“等效虚拟储能容量”的热韧性多维评价体系。结果表明：在热环境响应方面，PCM墙体较常规墙体降低室内峰值温度1.31℃，并将峰值出现时间延后约5 h，显著平抑了室内升温速率与温度波动；在环境热韧性方面，相变储热围护结构有效阻断了外部热冲击的室内累积效应，使IOD与OEF分别大幅降低66.33%和 65.57%，显著降低了建筑对极端高温的响应敏感性；在能源热韧性方面，相变储热围护结构在断电期间发挥了“分布式储热虚拟电池”作用，典型日累计提供等效被动冷量0.09 kWh/m

，有效填补了主动冷源失效后的能量缺口。研究证实了相变储能技术在保障极端工况下室内热安全与缓解电网供需矛盾方面的双重潜力，为气候适应性建筑设计提供了定量依据。

Abstract

To address indoor overheating risks caused

by extreme heatwaves compounded by power outages

this paper proposes a thermal resilience enhancement method using phase-change envelopes. Based on the EnergyPlus platform

a model incorporating a CaCl

·6H

O/EG composite PCM was simulated under the SSP5-8.5 future climate scenario. A multidimensional framework

including Indoor Overheating Degree (IOD)

Overheating Exceedance Factor (OEF)

and "equivalent virtual energy storage capacity

" was established to evaluate performance. Results indicate that the PCM wall reduced peak indoor temperature by 1.31°C and delayed the peak by 5 hours. It significantly enhanced environmental resilience by lowering IOD and OEF by 66.33% and 65.57%

respectively. Functioning as a "distributed thermal-side virtual battery

" the PCM layer provided 0.09 kWh/m

of passive cooling during outages. This study validates the potential of phase-change technology for ensuring thermal safety and bridging energy gaps in climate-adaptive building design.
