摘　　要：玻璃采光顶中庭被广泛应用于高校图书馆设计中。设计师追求通透的空间效果使采光顶玻璃面积越来越大。合理设计玻璃采光顶遮阳设施对提升室内环境舒适度有重要意义。以寒冷地区山东省某高校图书馆的采光顶中庭为研究对象,通过实地测试和现场调研分析中庭室内热环境存在的问题,并建立分析模型,基于DesignBuilder和Ecotect软件分析了采用不同材料、不同构造形式的遮阳改造对图书馆中庭的室内温度、能耗和自然采光的影响,提出适宜于采光中庭遮阳改造的构造方式及做法。其中,采用高反射率-低透射率卷帘遮阳方式,其节能和降温效果最明显;采用低反射率-低透射率遮阳方式,其中庭的自然采光均匀度最佳;而采用高反射率-低透射率遮阳方式,其中庭的自然采光均匀度次之。结果表明,综合考虑节能和自然采光的情况下,采用高反射率-低透射率卷帘遮阳效果最好。The glass-roofed atrium is widely designed for university libraries. The architects pursue transparent space to make the glass area of the lighting roof larger and larger. The rational design of the glass lighting roof shading facilities is of great significance for improving the comfort of the indoor environment. Taking the atrium with lighting roof of a university library in a cold area in Shandong Province as the research object, the problems of the indoor thermal environment in the atrium were analyzed through field tests and on-site investigations, and an analysis model was established. Based on DesignBuilder and Ecotect software, different materials and different structures were analyzed. The influence of the form of shading on the indoor temperature, energy consumption, and natural lighting of the library atrium, the construction method, and method suitable for the shading of the lighting atrium is proposed. Among them, the high-reflectivity-low-transmittance roller blind shading has the most obvious energy-saving and cooling effects;the low-reflectivity-low-transmittance shading has the best natural lighting uniformity in the courtyard, the high-reflectivity-low-transmittance shading is the second. The results show that the high-reflectivity-low-transmittance roller blinds are the best when considering energy saving and natural lighting.
