摘　　要：为研究水平外遮阳构件在办公建筑中优化室内光环境和节能的重要作用,评估其对能源效率和舒适性的影响,本研究通过模拟分析和实地调查,探讨了遮阳结构布置次数、朝向和遮阳构件之间的间距等对建筑节能的影响,揭示了不同遮阳参数下的照明、热环境和能耗效果。实验结果表明:在特定的寒冷地区,出挑长度为0至1.1 m时能够实现约12%的节能效果,节能效果最为显著,但超过这一长度后,其效果开始减弱。采用单层双遮阳板设计比单层单遮阳板更有利于节能,南向和西向的遮阳对建筑的能耗影响更加显著。然而,虽然外遮阳有助于降低夏季的空调能耗,但它也可能增加冬季的采暖和照明能耗。水平外遮阳在办公建筑节能方面的效果确实存在,但节能效果受到多种因素的影响,包括遮阳参数设计、地理位置等,本研究为办公建筑遮阳设计提供了重要的参考和启示。To investigate the significant role of external horizontal components in office buildings for optimizing indoor lighting envi⁃ronments and energy conservation,and to assess their impact on energy efficiency and comfort.This study,through simulation analysis and field investigation,explored the effects of the arrangement frequency,orientation,and spacing between shading com⁃ponents on building energy conservation,in order to reveal the lighting,thermal environment,and energy consumption outcomes of different shading designs.The experimental results showed that in specific cold regions,a projection length of 0 to 1.1 m can achieve approximately 12%energy savings with the most significant effect,but beyond this length,the effect begins to diminish.A single-layer double shading panel design is more effective in energy conservation than a single-layer single shading panel,with shading on the southern and western orientations having a more pronounced impact on building energy consumption.However,al⁃though external shading helps reduce air conditioning energy consumption during summer,it may also increase heating and light⁃ing energy consumption in winter.The effect of horizontal external shading on energy conservation in office buildings indeed exists,but the energy-saving effect is influenced by various factors,such as design choices and geographical location.This study provides important references and insights for shading design in office buildings.
