中文简介

被动辐射冷却(PRC)技术因其无能源和环保的特点而被应用到建筑中,特别是以中国建筑围护结构的形式。然而,大多数现有研究都集中在将中国建筑围护结构应用于孤立的建筑物上,而很少有研究考虑了周围高反射率的中国建筑的阴影和反射对建筑性能的影响。为了弥合这一差距,对位于佛罗里达州迈阿密九栋建筑社区中心的一栋高层公寓 (HA) 进行了案例研究。通过 Radiance 和 EnergyPlus 对不透明的中国建筑围护结构和周围建筑物(SB)对采光和能源性能的综合影响进行了数值分析,并分析了辐射冷却材料(RCM)、建筑方向和社区布局的变化。结果表明:在目标 HA 上采用 RCMs 后,忽略 SBs 可高估外墙累积辐射 96.19 %,空间日光自主性(sDA)高估 39.13 %,空调总能耗高估 8.28 %,低估空间眩光自主性(sGA)21.27 %。优化 RCMs 和 SBs 的协同效应可以在采光和能源性能之间取得平衡,产生

英文摘要(原文)

Passive radiative cooling (PRC) technology has been incorporated into buildings, especially in the form of PRC building envelopes due to its energy-free and eco-friendly features. However, most existing studies focused on applying PRC building envelopes to an isolated building, while scarce research has considered the impacts of shading and reflection from surrounding highly reflective PRC buildings
