Examination of materials and lighting systems in university libraries with selected examples: A design proposal for library of Çukurova University

University libraries, which are central to access to information and learning processes, provide students with a wide range of information sources and an effective working environment. Lighting systems in university libraries are a tool to support users' access to information and learning processes. This thesis studies interior building materials and lighting systems used in libraries of different universities and their usability features are discussed. Because library environments require a balanced combination of functionality, aesthetics, and comfort in learning and working environments. Elements such as appropriate material selection and lighting design are addressed to meet the needs of existing library environments and improve the user experience. The building materials and lighting systems used in library interiors are important in increasing user's work performance and ensuring comfort. Proper selection of building materials and effective lighting arrangements can improve students' ability to focus and optimize their study efficiency. The research has revealed the current state of lighting systems in university libraries and has a guide for future developments. According to analyses, it is determined that the lighting systems of the reading rooms and common rest areas in the library buildings of all the universities examined are suitable. Keywords: Library, material, artificial and natural lighting systems.
