光伏玻璃应用于办公空间的天然光环境研究--以天津地区为例

摘要

Against the backdrop of the global energy and environmental crisis, how to make the building from energy consumption to energy making, BIPV ( Building Integrated Photovoltaic) system provides an effective solution.Compared with the traditional opaque photovoltaic modules, photovoltaic glass at the same time generates electricity, and changed the natural light indoor environmental quality.In this paper, a dynamic simulation software Daysim was used to analyze the natural light when using different cell coverage area ratio of photovoltaic glass in different directions of office space.DA and UDI were compared and analyzed in different applications toward the ideal daylighting environment in office space and the optimal battery coverage area ratio of the photovoltaic glass were found.%在全球能源与环境危机的大背景下，如何使建筑在节能的同时从耗能转化为产能，光伏建筑一体化BIPV （ Building Integrated Photovoltaic）系统提供了一种有效的解决方式。光伏玻璃在发电的同时改变了室内的天然光环境质量。利用动态天然光模拟软件Daysim，对不同电池覆盖面积比的光伏玻璃应用于不同朝向办公空间的全天然采光时间百分比（ DA）、有效照度（ UDI）进行对比分析，得出在不同朝向办公空间应用光伏玻璃时满足天然光环境质量要求的最佳电池覆盖面积比。
