【摘要】：建筑的自然采光对于使用者来说十分重要，不仅能提高人们学习工作效率，更有益于人的身心健康。近年来，越来越多的建筑中出现中庭，中庭空间对于建筑功能和建筑物理环境都十分重要。充足的自然光对于塑造一个高品质的、令人愉悦的中庭空间起着非常重要的作用。而在中庭设计过程中考虑到采光问题，就有机会为中庭附属空间带来更多的自然采光，从而降低建筑运行中的照明能耗及部分空调能耗，为整个建筑的节能减排做出了一定的贡献。不同的中庭空间形式和中庭围合界面材质会为中庭采光带来不同的效果，本文重点研究了建筑中庭剖面形式的变化对垂直墙面采光系数分布的影响。论文首先通过人工天穹缩尺模型实际测试验证计算机光学模拟软件Desktop Radiance的模拟准确性，然后使用该软件对大量模型进行光环境模拟，通过对模拟结果的统计和分析，最后得出不同剖面形式对应的中庭垂直墙面采光系数分布的特点。本文共研究了四种剖面变化类型——倒金字塔形、正金字塔形、奇数层向内突出、偶数层向内突出，这四个剖面类型的中庭与垂直墙面直上直下的同高参考模型进行对比，分析得出相应的变化规律，并结合不同的建筑类型对光环境的要求，提出相应的设计策略，以提升建筑中庭的光环境品质。作者希望论文中所做的基础工作能对今后更深入的研究起到帮助，，同时能够为今后的建筑中庭光环境设计提供一些参考。
[Abstract]:The natural lighting of architecture is very important for users, not only to improve the efficiency of learning, but also beneficial to the physical and mental health of people. In recent years, more and more buildings appear in atrium. Atrium space is very important for architectural function and architectural physical environment. Pleasant atrium space plays a very important role, and in the atrium design process, there is an opportunity to bring more natural lighting to the atrium subsidiary space. In order to reduce the building operation of lighting energy consumption and part of the energy consumption of air conditioning. Different atrium space forms and atrium surrounding interface materials will bring different effects for atrium lighting. In this paper, the influence of the profile of the atrium on the distribution of the lighting coefficient of vertical wall is studied. Firstly, the computer optical simulation software Desktop is verified by the actual test of the artificial scale model of the celestial dome. The simulation accuracy of Radiance. Then the software is used to simulate the light environment of a large number of models, through the statistical analysis of the simulation results. Finally, the characteristics of the distribution of lighting coefficient of vertical atrium wall with different profile forms are obtained. In this paper, four types of profile changes are studied: inverted pyramid, positive pyramid, odd layer protruding inward. Even layers protruding inward, the four sections of the atrium and vertical wall straight up and down the reference model of the same height to compare, analysis of the corresponding changes, and combined with different building types of the requirements of the light environment. The corresponding design strategy is put forward in order to improve the quality of light environment in the atrium. The author hopes that the basic work in this paper will be helpful to the further research in the future, and can also provide some references for the design of the atrium light environment in the future.
