Abstract |
The purpose of this study is to find the base experimental data by testing the recovery time of human eye with administrating experimental conditions, source luminance, background illuminance and the position of subjects, by examining the appropriateness of evaluating discomfort glare caused by actual window and by simulated window. The process of this study is as follows: 1) In terms of the previous experiment, the large of Mock-up, evaluation values and subjective positions were administrated. 2) The experiment on the recovery time of human eye is conducted by source luminance, background illuminance and the subjective position. 3) At the same Mock-up condition, the experiments for evaluating discomfort glare caused by actual window and by simulated window were conducted and contrasted. Rationally tested recovery time of human eye is 120 seconds with source luminance, background illuminance and the subjective position. And the difference on the boundary of evaluating values caused by actual window and by simulated window ranges from 13% to 5%. On the basis of the result, the validity of discomfort glare evaluation caused by simulated window is presented. |
