基于天然采光的中小学侧窗形式优化设计策略研究——以夏热地区为例

Research on Optimal Design Strategy of Side Windows in Primary and Secondary Schools Based on Natural Lighting:A Case of Hot Summer Area

教学类建筑的室内光环境对学生的身心健康有着较为重要的影响,舒适的光环境在提高学习效率、降低视觉疲劳方面有着积极作用。利用ladybug+honeybee模拟不同窗间墙宽度和侧窗高宽的尺寸工况下教室内的采光环境,研究结果显示,窗间墙尺寸的减小能够局部改善近窗区域易产生眩光的问题,且窗间墙宽度为450 mm时室内采光均匀度最佳;相同窗地比的情况下增加窗扇高度,有利于向走廊侧延伸光舒适区域,以及提高采光均匀度。

The indoor light environment of teaching buildings has an important impact on students’physical and mental health.The comfortable light environment plays a positive role in improving learning efficiency and reducing visual fatigue.This paper uses ladybug+honeybee to simulate the lighting environment in the classroom under different working conditions of wall width between windows and side window’s size.The results show that the reduction of window wall size can partially modify the glare near the window area,and the indoor lighting uniformity is the best when the window wall’s width is 450mm.Increasing the window height under the same window to ground ratio is conducive to extending the light comfort area to the corridor side and improving the lighting uniformity.
