Building occupants prefer to live and work in spaces with good daylight distribution. Particularly the daylight presence for indoor illumination, affects occupants satisfaction, performance and also productivity. Moreover suitable daylight in interior lighting design with optimal integration between daylight and electrical light could obtain energy saving. On the other side, a high availability of daylight levels in indoor environment could be a disadvantage for the optimal visual conditions and can cause glare phenomena. The evaluation of visual performances and comfort in the indoor environment caused by daylighting is characterized by its variability during the time. Therefore, daylight discomfort glare is difficult and complex to evaluate due to the width of the source and the wide range of variation of the luminance values. The object of this study is to compare the evaluation index of daylight glare, DGI with the results of perceived evaluation of discomfort glare. To compare the results, discomfort glare experiments with non uniform glare source was conducted. The artificial window was modeled and divided to 3 surface equally. Furthermore applicability of DGI and possible changes are also discussed. |
