摘　　要：以夏热冬冷地区的合肥和芜湖两个城市的13所高校图书馆作为研究对象,对图书馆南向阅览室单元进行实测调研,将调研阅览空间的基本空间尺寸进行整理分类,总结出基础阅览空间模型,阅览室所使用的不同遮阳形式进行体量遮阳和构件遮阳的分类作为室内光环境质量影响因素,利用性能化软件在全年动态光环境仿真模拟,以采光系数平均值和有效自然光照度时间百分比为室内光环境质量评价标准,得出自然采光高校图书馆外遮阳形式的不同设计影响因素下室内光环境的质量情况;初步得出体量遮阳和构件遮阳对于室内光环境的状况有一定的改善作用,其中水平出挑阳台遮阳结合水平百叶遮阳的体量遮阳中出挑阳台尺寸为1.2 m,水平百叶遮阳高度为1.2 m的遮阳形式整体的室内光环境质量表现较好,柱廊结合格栅构件遮阳中柱廊进深为1.8 m,方格格栅构件高度为1.2 m的遮阳尺寸表现较好,水平遮阳板采用多层板遮阳的整体表现较好,以上具体外遮阳形式尺寸可以对于夏热冬冷地区图书馆外部形式设计研究提供设计参考。Taking 13 university libraries in two cities of Hefei and Wuhu located in the hot summer and cold winter areas as the research objects,a field survey is carried out on the south-facing reading room unit of the library,and the basic spatial dimensions of the surveyed reading space are sorted and classified,and the basis is summarized.The reading space model,the diferent shading forms used in the reading room are classified as the mass shading and component shading as the influencing factors of the indoor light environment quality,and the performance-based software is used to simulate the dynamic light environment throughout the year.The percentage of illuminance time is the evaluation standard of indoor light environment quality,and the quality of indoor light environment under different design influencing factors of the external shading form of natural lighting university library is obtained.There are certain improvement effects.Among them,the size of the overhanging balcony is I.2 m,and the height of the horizontal louver is I.2 m.The overall indoor light environment quality is better,and the colonnade combined with the grille.The depth of the colonnade in the component shading is I.8 m,and the shading size of the grid component height is 1.2 m.The external form design research of cold area library provides design reference.
