基于HDR实测的高校教室采光环境评价研究

An Investigation of Daylighting Quality within University Classrooms Based on HDR-Image Technique

本研究以高校教室天然光环境为研究对象,采用主观问卷收集使用者的视觉评价,采用高动态图片收集使用者所经历评价的天然光环境数据。数据分析表明,使用者对天然光环境的舒适度、满意度和愉悦程度评价均呈正相关性,而兴奋程度和刺激程度与前三项评价因子均呈负相关。水平工作面照度和眼部垂直照度与视觉评价的相关性较好,眩光指数DGP(Daylight Glare Probability)比DGI(Daylight Glare Index)对主观评价的预判性更高。

This paper investigates daylighting quality in classrooms at a university.Subjective visual appraisal was collected by online survey,and luminance distributions were measured through the High Dynamic Range Image Technique.Based on data analysis,subjective daylighting comfort,satisfaction and pleasure were positively correlated with each other.Daylighting excitement and stimulation were negatively correlated with these three factors,respectively.Horizontal and vertical illuminance presented a good performance in terms of predicting visual appraisal.Moreover,DGP outperformed DGI in terms of predicting visual appraisal.
