Uniformity ratio and artificial light requirement calculations used in the paper The Role of Light Shelf and Window Size on Daylight Performance of an Architecture Studio

The files present the uniformity ratio and artificial light requirement of an educational building in İzmir, Turkey. The results of this paper are published in the International Journal of Digital Innovation in the Built Environment. Kindly see the abstract below to find out more: Daylight affects our health and comfort. Recently, occupants have faced thermal and visual comfort problems due to a lack of solar control elements and wrong design decisions of glazed surfaces. Recent studies show that solar control systems and window-based variables are among the most significant variables that influence daylight performance. This study tests various combinations of window sizes and light shelf scenarios for a uniform distribution of daylight and visual comfort of occupants in two architecture studios in the İzmir Institute of Technology (IZTECH) Campus. In scenarios, window size and location, exterior and interior light shelves' height, incline angle, and materials are tested. It is concluded that variables significantly improved the uniform distribution of daylight of both studios and sun patch areas of the south/east-oriented studio. Also, the artificial light requirement of the south/west-oriented studio is improved by 29.36% and 31.75% for the 21st of June and December, respectively.

本数据集收录了土耳其伊兹密尔某教育建筑的采光均匀率与人工照明需求相关数据。本研究成果已发表于《国际建筑环境数字创新期刊》（International Journal of Digital Innovation in the Built Environment）。详情请参阅如下论文摘要：天然采光对人类健康与舒适度具有重要影响。近年来，由于缺乏有效的遮阳调控构件，且玻璃幕墙设计决策失当，建筑使用者常面临热舒适与视觉舒适双重困扰。现有研究表明，遮阳系统与窗户相关变量是影响天然采光性能的核心因素之一。本研究针对伊兹密尔理工学院（İzmir Institute of Technology, IZTECH）校区内两间建筑设计工作室，测试了多种窗户尺寸与采光搁板（light shelf）组合方案，以优化天然采光均匀分布并提升使用者的视觉舒适度。本次测试方案涵盖窗户尺寸与位置、内外采光搁板的高度、倾斜角度及材质。研究结果显示，上述变量可显著改善两间工作室的天然采光均匀度，同时优化了朝东南向工作室的阳光光斑分布状况。此外，朝西南向工作室的人工照明需求在6月21日与12月21日分别降低了29.36%与31.75%。若有任何疑问、咨询或合作意向，欢迎随时联系笔者。
