天井式民居的自然采光仿真模拟

The Natural Lighting Simulation of the Traditional Dwelling Residence

传统天井式民居的窗户性能显著影响室内自然采光水平。本研究对江西省金溪县浒湾村天井式传统民居进行了仿真模拟,旨在确定传统天井式住宅室内自然采光的最佳策略。结果表明,窗地比至少应达到为1/6,高窗和普通窗组合运用是理想的选择,窗棂对室内自然采光的影响最小。运用Ecotect软件得出的采光策略提高了室内自然采光,使用照度计现场测量的传统方法并不准确。

The performance of the window of a traditional dwelling architecture significantly influences the natural lighting level of such a building. This study aims to determine the best strategy for the natural lighting of traditional dwelling architecture by examining No. 37 residence in Huwan village. Window- floor ratio,window position,and window lattice were studied through Ecotect software involving lighting simulations.Results show that the optimum window- floor ratio is 1 /6. The combination of high windows and ordinary windows is the ideal option to improve the natural lighting. The window lattice exerts a minimal effect on natural lighting increase. Adopting the best natural lighting strategy combination can further improve indoor natural lighting. Future research should be directed toward applying Ecotect software to quantitatively evaluate the lighting effects of other components of traditional dwelling architecture and produce the best natural lighting strategy combination.
