عنوان انگلیسی Parametric study of skylight design parameters to improve the indoor visual quality in exhibition areas
چکیده انگلیسی مقاله Daylight is one of the most influential parameters of visual quality, especially in spaces like art exhibitions. Skylights are proper choices to provide daylight, improve visual comfort, and reduce artificial lighting energy consumption. In this paper, the effect of the main design parameters of skylights on the visual quality is studied using DesignBuilder software. An 81 m2 exhibition area is assessed as a test case. The design variables are the skylight form, orientation, location, glazing type, and splay angle. Also, luminance uniformity, spatial daylight autonomy (sDA), and useful daylight illuminance (UDI) are used as evaluation metrics. The north-oriented curved skylight leads to the best visual quality among the studied cases based on the results. Installing the skylight on the north side of the exhibition roof is better to provide the best luminance uniformity. Besides, the results showed that triple Low-E glazing provides the most uniform and the least maximum luminance. However, it may slightly reduce sDA. Finally, although the effect of splay angle on the visual comfort indexes depends on the intended time, 45° to 60° angles work satisfactorily.
