Influence of library building design features on daylighting of reading spaces

Abstract

Library building design features contribute to the performance of indoor daylight. Reading spaces in library buildings require effective daylighting for high productivity. This study evaluated the indoor daylight quality of three reading spaces, namely Esut-Hall A, Esut-Hall C, and Esut-Hall F, located in the main library of Enugu State University of Science and Technology (ESUT). The research aimed to assess the influence of individual building design features on the daylight performance of these spaces. The study adopted case study research, in combination with building simulation with Velux daylight visualizer software. The first result identified sixteen building design features that influenced the daylight quality. The second result indicated that the daylight quality values of Esut Hall A and Esut Hall F passed the 50% threshold for mean UDI300lux-2000 lux DA, UDI300lux-500 lux DA, and DF, showing that they have good daylight quality. For the remaining reading space, it was recommended that the area of the effective windows should be increased, and top light windows should be introduced.
