天空亮度分布是研究建筑采光的基本资料。研究建筑动态采光要求量化年周期内天空亮度动态分布,本课题提出了通过三种标准天空亮度分布模型的分量进行叠加以近似拟合某时刻天空实际亮度分布的构想,并以此为基础建立动态天空亮度模型。本文主要介绍了三种标准天空确立的研究方法、分量叠加方式及该模型校验测试方式。%The sky luminance distribution is the basic material of architectural lighting research. The research of building dynamic daylighting requires quantifying the annual cycle of sky luminance distribution. This paper proposes a sky model superimposed by three standard sky model components which could approximately fit the real sky luminance distribution. Based on this sky model, this research establishes a dynamic sky luminance distribution model. This paper introduces the research method, superimposing algorithm and the model validation test.
