Abstract

Many studies today reveal daylight’s effects on human health, especially the circadian cycle, and its potential regarding energy efficiency. In this aspect, the importance of studies in the field of daylight in terms of sustainable architectural design is increasing day by day. Only cloudy sky conditions can be evaluated with the daylight factor method, which has been used for many years to determine the daylight performance of the room. It is considered appropriate to use this method in regions where cloudy sky conditions prevail for most of the year, such as Northern European countries. On the other hand, where different sky conditions occur throughout the year, it is recommended to use dynamic calculation methods using climate data generated at one-hour steps or shorter time intervals. Both methods are included in EN17037: 2018 Daylight in Buildings Standard published in 2018. Turkey consists of regions with different annual sunshine duration and radiation intensities. To choose the appropriate method for computational daylight studies that would be carried out in these regions, the two methods' effect on the room's daylight performance should be evaluated. In this study, a theoretical living space, which is frequently used in architectural applications, is designed and via the Grasshopper, the plugin of the Rhinoceros program, the daylight provision performance of the room is calculated for both calculation methods. The results are visualised on the Turkey map, and the expression for comparison is strengthened. This study aims to contribute to the determination of the appropriate calculation method and the selection of the appropriate simulation tool (dynamic/static) in computational daylight studies to be carried out in different regions of Turkey.
