| dc.description.abstract | Designing a proper daylight is very crucial when it comes to engineering and architecture. Such considerations provide various benefits in terms of increasing visual comfort and decreasing energy demands. The purpose of this study is to develop a new daylight performance metric that is suitable for dynamic facades. To fulfill this purpose, a modified daylight metric has been developed which consists of Dynamic Useful Daylight (DUD) to measure the work plane area that receives a desired daylight illuminance and Dynamic Sunlight Exposure (DSE) to measure the work plane area that receives excessive direct sunlight. The design configurations involved in this study are; the base case scenario (without any louver), fixed shading louvers and dynamic shading louvers. Moreover, the study manipulates different parameters such as the tilt angles of the louvers, the width of the louvers and the spacing between two louvers to determine the best configuration that provides the ultimate daylight in three different days of the year. Through this study, it has been obtained that the maximum Dynamic Useful Daylight (DUD) can be achieved by using dynamic shading louvers as opposed to not using shading louver at all or using the traditional fixed shading louvers. Specifically, it has been obtained that using dynamic shading louvers achieves an annual average Dynamic Useful Daylight (DUD%) of 35%, 29%, 33%, and 31% on the southern, northern, eastern, and western orientations, respectively. | en_US |
