Abstract

The level of glare produced by nine textiles was evaluated. This type of shading system is often marketed without an adequate photometric characterization, which leads to an inadequate application. This results in higher visual discomfort for users and higher energy consumption. In order to evaluate glare, four different metrics were calculated. These metrics are based on the effect of saturation, contrast or both. It was also evaluated which metric should be used: one specific to the prevailing light condition, a general metric applicable to all light conditions, or a combination of both. In this study it was observed that the contrast metric was more sensitive to glare, but the use of two metrics in an additive way provides a better ranking of textiles. As a final objective, a scoring system is proposed to evaluate the glare performance of textiles.
