Prediction of discomfort from glare from daylight in classrooms

Daylighting is desirable in classrooms but can pose a challenge to classroom illumination when there risk of discomfort from glare windows and sunlight. There are several metrics use for the evaluation daylight, none has yet been validated based on field-of-view conditions classrooms. A previous study found that Daylight Glare Probability (DGP) produced relatively better predictive power reported compared other metrics. However, metric tended correlate weakly with positions away window light source classroom. This prompted current investigation possibility improving DGP equation. The modified equation significantly fit subjective evaluations dataset comprising 184 49 participants collected results suggest be improved predict board-based work classroom, particularly logarithmic form adaptation term integrated
