Abstract
Daylighting is one of the most important affairs because of its importance in saving energy consumption and visual comforts inside space for occupants. The research aims to study the effect of changing the Window-to-Wall Ratio (WWR), and using horizontal shading devices for the southern spaces of Clean Water and Sewerage building in Dakahlia to improve daylighting performance in the office buildings. This methodology is carried out in four phases: The first phase, study of the current condition of daylighting level in the southern space. The second phase, reducing the number of windows. The third phase, parametric analysis for WWR values. Fourth phase, parametric analysis for horizontal shading devices. The implementation of the simulation process is carried out  by using the Grasshopper for Rhino software, which supports simulation parametric model process and the use of Ladybug & Honeybee for Grasshopper tools, which were used to improve daylighting  performance  in the southern office spaces where daylighting is insufficient. The simulation process performed by using spatial Daylight Autonomy (sDA 300/50%) and Annual Sunlight Exposure (ASE 1000/250) metrics with integration of LEED V4.1 criteria. Results demonstrated that the effect of changing WWR values on daylighting performance inside the space. The research is recommended to using horizontal shading devices as they achieve the required values of sDA and ASE according to LEED V4.1  criteria  and achieve glare DGP inside the southern space, so that the occupant does not have to close the windows and rely on artificial lighting and thus increase energy consumption.
