Resumen
Se evaluó el nivel de deslumbramiento producido por seis textiles diferentes. Este tipo de sistema de sombreado es comercializado sin una adecuada caracterización fotométrica, lo que conlleva a una aplicación inadecuada de los mismos. Para evaluar el deslumbramiento, se calcularon tres métricas a través de la técnica HDR. Estas métricas son: Iluminancia Vertical a Nivel de los Ojos (Ev), Índice de Deslumbramiento de la CIE (CGI) y Probabilidad de Deslumbramiento con Luz Natural (DGP) y están basadas en el efecto de saturación (Ev), contraste (CGI) o ambas (DGP). Asimismo, se evaluó qué métricas conviene utilizar, si una específica a la condición lumínica predominante o una métrica general aplicable a todas las condiciones lumínicas. En este estudio se observó que la métrica exclusivamente de contraste (CGI) fue más sensible que una métrica general (DGP). Asimismo, se observó que sólo un textil se destacó en cuanto al control de deslumbramiento: El 4308.
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.
