Intervention Study on the Impact of Sunlight Intensity on Uncomfortable Glare Indicators in Daylighting Environment of Office Spaces
The evaluation indicator for daylight discomfort glare basically consists of saturation effect parameters and contrast effect parameters.The relationship between these two types of parameters and the discomfort glare perception determines the overall prediction accuracy of the indicators.However,the academic community has not reached a consensus on the correlation between the two types of parameters and discomfort glare,which in turn affects the selection of glare evaluation indicators.It has shown that the intensity of sunlight within the field of view affects the accuracy of evaluation indicators for discomfort glare in some previous studies.This article investigated the glare prediction accuracy of commonly used saturation& contrast effect parameters with the field experiment under two conditions of sunlight intensity(greater than and less than 1000 lx),which including a subjective questionnaire to collect discomfort perception of testers and the analysis of variance to conduct correlation analysis.This study identified the differences in glare discomfort prediction between saturation effect and contrast effect parameters in existing glare evaluation indicators under different sunlight intensities,verified the impact of sunlight intensity on the accuracy of glare discomfort evaluation indicators,and provided guidance and reference for the application of evaluation indicators for glare discomfort in different daylighting scenarios.
