摘　　要：为了对商业广场风雨步行街采光顶的光热性能进行整体评价,提出兼顾舒适、经济、节能三者的优化设计方案,现以北京某商业广场风雨步行街为实例,运用模拟计算软件对其步行街采光顶在无遮阳、采用内遮阳(实际采用的遮阳方式)、采用外遮阳这3种情况下分别进行模拟计算,分析其3种情况下步行街室内的采光效果、透入太阳辐射热程度,最后提出优化建议。In order to make art integated evaluation to the daylight and thermal performance of glass roof of business street, and offer a proposal who emphasizes on comfortability, economical efficiency and energy efficiency simultaneously, now take a business walking street project in Beijing as example to make numerical simulation and analysis under three conditions： glass roof without shading, glass roof with fabric inner shading, glass roof with fabric exterior shading. Analyze the natural lighting effect, penetrated solar radiation of the indoor walking street under each condition. Finally put forward an optimizing suggestion.

关 键 词：商业步行街 采光顶 光环境 热工性能 外遮阳 内遮阳
