Abstract
The objective of this study is to investigate the limiting glare index for Thai elderly in sport and recreation areas. The study made a survey glare from small (luminaires) and large sources (windows) using DIALux for evaluating Unified Glare Rating (UGR) and Photolux program for assessing Daylight Glare Index (DGI). Discomfort glare of Thai elderly was also evaluated. Three indoor sport centers were explored. And, three areas were investigated, which are walkway, activity area, and seating area. There were 230 Thai elderly participated in the study. Data was analysed using Linear Regression Analysis. Results showed that, in overall, limiting glare indices for small source in indoor sport center are lower than an international standard about 1–7 units. The results also illustrated that limiting glare indices for large source in indoor sport center are lower than the international standard. But, the difference is 5–8 units.
