幼儿园生活单元采光性能的绿色建筑提升方法

Green Architectural Enhancement Method for Daylighting Performance of Kindergarten Living Units

研究通过提升幼儿园生活单元的采光性能,目的在于创造幼儿园生活单元健康绿色的室内天然光环境,关键问题是“建筑提升方法”的量化表达及绿色建筑评价。应用6种绿色建筑提升方法对幼儿园生活单元在不同的工况下进行实验,间距法采光性能指标最低,切分法采光性能指标最高。结论认为:生活单元的日照间距并不是影响采光性能的关键因素;生活单元的窗地面积比增加,采光性能会相应提升,但生活单元窗的位置及空间组合模式与采光性能提升也密切相关;切分法对于提升生活单元的采光性能表现最好,最值得在设计实践中推广。

The study aims to create a healthy and green indoor natural light environment in the kindergarten living units by enhancing the daylighting performance of the unit.The key of the study lies in the quantitative expression of the"architectural enhancement method"and assessment for green buildings.Six green architectural enhancement methods were applied to the kindergarten living units under different working conditions,and the spacing method had the lowest and the splitting method had the highest daylighting performance index.It is concluded that the sunshine spacing of living units is not a key factor affecting daylighting performance.The daylighting performance will be enhanced by increasing the glazing-to-floor area ratio of living units,but the window position and spatial combination pattern of living units are also closely related to the enhancement of daylighting performance.The splitting method performs best in enhancing the daylighting performance of living units and is most worthy of promotion in design practice.
