DESLUMBRAMIENTO MOLESTO EN TEXTILES

MÉTRICAS BASADAS EN EFECTO DE SATURACIÓN Y/O CONTRASTE

Abstract

The level of glare produced by six different textiles was evaluated. This type of shading system is marketed without an adequate photometric characterization, which leads to an inappropriate application of them. In order to evaluate glare, three metrics were calculated through the HDR image technique. These metrics are: Vertical Illuminance at Eye Level (Ev), Cie Glare Index (CGI) and Daylight Glare Probability (DGP). These metrics are based on the saturation effect (Ev), contrast (CGI) or both (DGP). Likewise, it was evaluated which metrics should be used, whether one specific to the predominant light condition or a general metric applicable to all lighting conditions. In this study, it was observed that the exclusively contrast metric (CGI) was more sensitive than a general metric (DGP). Likewise, it was observed that only one fabric was the best in terms of glare control: The 4308.
