Evaluation of Daylight and Glare Quality of Office Spaces with Flat and Dynamic Shading System Facades in Hot Arid Climate

There has been an increasing awareness in recent years about the evaluation of daylight and glare quality in buildings. In the study, an office space with a flat and a dynamic shading system facade (triangular cell facade) is discussed in the province of Mardin, which is in a hot and arid climate zone. Observing two different facade types in a single office space allows the study to be carried out in detail, and their suitability can be checked by producing quick design alternatives. The analysis and evaluation of daylight and glare quality over office spaces with two different facade types aims to develop an innovative approach. This objective is designed to respond to climatic conditions and contribute to the development of climate-sensitive designs. The study was parametrically simulated with the Grasshopper plugin and daylight plugin ClimateStudio tools in Rhino, an office space with both a flat facade and a dynamic shading system facade located in a hot-arid climate. As a result of the analysis, the dynamic shading system, which can transform according to the position of the sun, shows outputs in accordance with the LEEDv4 standard, minimizing the ASE value of the facade's annual sunlight exposure by up to 10%, while maximizing the spatial daylight autonomy sDA value by 60% or more. In addition, Daylight Glare Probability (DGP) values of 0.38 keep the visual quality affective. As a result, the office space with a dynamic shading system facade showed that it can significantly improve the flexibility of shading to control daylight measurements and glare, achieving the maximum level of visual comfort based on the LEEDv4 certificate.
