Abstract: Museums consume a lot of energy in China, so setting up skylights in museums can effectively reduce energy consumption via lighting. Ancient ruins museums, as a specific type of museum, experience contradictions between natural lighting needs and site protection which needs to be studied further. Through field research and measuring exhibition halls of two ancient ruins museums in the Guangdong area, this research examines their lighting situations and then simulates and analyses their lighting using sunlight simulation software named VELUX Daylight Visualizer 2. Finally, the research proposes that integration of lighting and shading is the right way to optimise the skylights ancient ruins museums' exhibition halls in Guangdong. For example, a glass roof skylight should be combined with translucent material. Light reflection structure are suitable for decentralised daylight openings. These findings provide reference for the design and optimisation of skylights for ruins museums in Guangdong district.

摘要： 我国博物馆能源消耗巨大，在博物馆中合理设置采光天窗能有效降低照明能耗。遗址博物馆作为博物馆的一种类型，对其自然采光需求和遗址保护之间的矛盾亟需进一步研究。通过对广东地区遗址博物馆实地调研和对其中两个博物馆展厅的光环境测量，梳理了这一类型博物馆中展厅天窗导致局部出现眩光、整体照度过高或采光不均匀的采光现状，然后利用日光模拟软件VELUX Daylight Visualizer 2进行模拟分析，提出广东地区遗址博物馆展厅的天窗优化设计方法——天窗遮阳整合设计。例如全玻璃顶天窗设计可整合发光天棚、条形天窗可整合漫反射结构优化设计的策略，以期为广东地区遗址博物馆展厅天窗优化设计提供借鉴。
