传统花窗形态的天然光性能模拟研究——以0.1窗墙比为例

A Daylighting Simulation Study of the Form of Traditional Chinese Windows Based on a Window-to-Wall Ratio of 0.1

花窗是中国传统建筑的一种典型开窗形式,其常以"符号"的方式被应用于当代建筑设计。对花窗天然光性能的研究将为其设计应用提供量化依据,也为传统视觉环境的探究提供线索。本研究以典型单元空间为载体,基于0.1窗墙比对花窗进行穷举,结合基于动态光气候的天然光模拟技术,对花窗应用提出设计建议。

Traditional Chinese window is one of the typical elements of vernacular buildings in China. It has been increasingly applied in the area of contemporary architecture as a cultural symbol. The study of environmental performance of traditional windows will provide a quantitative basis for their design and applications, and therefore enhance the understanding of visual environment with them. In this article we investigated various traditional windows and their daylight performances in a typical single room, taking into account the window-to-wall ratio. Climate-based daylight modelling was adopted to produce dynamic daylighting performances in the room. As a result, some design guidelines and strategies were suggested to support modern building design based on current Chinese building regulations.
