博物馆展示空间采光设计的优化策略

针对博物馆展示空间的光环境现状，按照展品对采光的要求对展示空间进行分类，归纳出其典型的采光形式和展品陈列布局方式，通过计算展示空间在不同工况下的采光系数、采光均匀度、亮度分布和不舒适眩光指数等采光参数，对展示空间的光环境进行仿真分析，由此确定适宜的采光形式和采光构件，提出相应的采光优化策略，即从采光形式和构件两方面进行采光参数的优化。结果表明：采光优化策略可改善博物馆展示空间的采光质量，使不同类型展示空间获得适宜的光环境。

Optimization strategy to day-lighting design of exhibition spaces within a museum

As to the luminance environment of the museums, the day-lighting design in their exhibition spaces has been analyzed, the typical museum design factors, such as day-lighting form, and layout of displayed items have been concerned and investigated by field trips. Then, the exhibition spaces are classified into different categories whose natural day-lighting environments are simulated by the requirements of displayed items. Under varied day-lighting conditions, the daylight parameters, i.e. day-lighting factor, day-lighting uniformity, luminance distribution and discomfort glare index (DGI) are evaluated. Therefore, the favorable day-lighting form and members in the corresponding exhibition spaces will be determined. the optimization strategies which optimize the parameters of varied day-lighting forms and members are proposed. It is concluded that the day-lighting quality would be ameliorated by the implement of optimization strategies, and favorable luminance environment in the different exhibition spaces of a museum are achieved.
