This research introduces contemporary approaches to reintroduce natural lighting into established library building through the implementation of advanced daylight strategies, aiming to optimize the visual comfort essential for students. Utilizing cutting-edge technologies, particularly solar tubes, the study explores their application to enhance both visual and thermal comfort within existing library environments. The focus is on an autonomous structure within a university library at one of the engineering faculties in October City, employing simulation tools to forecast the efficacy of the proposed solution. The investigation delves into the impact of solar tubes on augmenting natural light penetration in dimly lit areas, emphasizing the potential advantages of revitalizing the natural lighting infrastructure in library spaces. Findings indicate a substantial enhancement in the natural lighting performance of library buildings through solar piping, leading to improved functionality for students and visitors, along with a notable reduction in energy consumption.
