Daylighting plays a crucial role in making the lecture room comfortable, particularly in terms of vision. Additionally, by lowering reliance on artificial lighting, it eases the load of electricity use. However, windows made of transparent glass let most of the sunlight inside, which degrades the visual clarity and causes glare. Therefore, strategies for limiting daylighting entry are crucial to solving the issue. One of the techniques is the use of window overhangs, including egg-crate, horizontal, and vertical forms. However, the utilisation of solely horizontal types of overhang is the exclusive subject of this study. In this study, the lighting in existing lecture room was analysed, and the impact of projections on the quality of lighting in lecture room was also looked at. This study employed the lecture room at the Faculty of Engineering and Built Environment (FKAB) known as the Seminar Room as a case study. The space is typically utilised for giving lectures as part of educational activities. Field measurements and simulations with Sefaira software were the methods employed for data collecting. By contrasting data from the simulations and field observations, the simulation software was also validated. According to the study, lecture room in the FKAB Administration Building are less successful when using a single horizontal window overhang. It is possible to contribute to a more sustainable building design with better daylight discoveries, especially for learning and teaching, by researching the most efficient horizontal projection ratio.
