The strategic architectural design aimed at maximizing natural light utilization for energy efficiency is of paramount importance. Daylight has consistently been a crucial factor in architecture, especially in sustainable design. However, the majority of daylighting studies have focused predominantly on office settings or small-scale scenarios such as single rooms. Given the rapidly increasing population, construction of high-rise buildings, particularly in larger cities like Tehran, has surged. Hence, investigating daylighting in high-rise residential buildings is significantly essential. This research aims to present and scrutinize strategies for sunlight penetration into deep spaces and assess the feasibility of implementing these methods in high-rise structures. Daylighting systems can satisfy the lighting needs of centrally located spaces that lack direct sunlight. They can significantly improve the quality of future housing by providing a tool capable of optimizing the quantity and quality of daylight. Providing adequate and desirable levels of daylight in residential units not only contributes substantially to energy saving but also enhances spatial quality within the units, fostering suitable living conditions for residents. In this study, daylight eva‎luation is undertaken using two dynamic indices: glare autonomy and daylight autonomy. The research employs a quantitative approach based on computer simulations to assess two of the most suitable daylighting systems (louvers and horizontal light ducts) for residential spaces. These simulations are conducted using a scripting algorithm in the Grasshopper software and optimized through brute force, facilitating parameter sensitivity analysis, and correlation matrix calculations. The study simulates 42 models for the louvers and 9 models for the sun ducts, totaling 5700 simulations. According to the simulations, the optimal design condition for the bedroom window louver is a 30-centimeter-deep louver, with a count of 8, a reflectance of 0.4, and an angle of +15 degrees. The optimal design for the sun duct involves a 0.4-centimeter-deep duct, a count of 25, and a reflectance of 0.8, which ensures maximum daylight. These conditions are discussed in detail within the paper.
