Optimisation of Daylighting Strategies in Educational Learning Environments in Nigeria: A Case for University Library Design

<p>Natural daylighting is a sustainable and cost-effective technique for improving indoor environmental quality in educational buildings, particularly in tropical regions such as Nigeria. University libraries, as centres of knowledge and extended student activity, require excellent visual comfort and low energy consumption. The aim of this study is to analyse and optimise daylighting systems in Nigerian university libraries in order to increase learning outcomes, user satisfaction, and energy efficiency. The objective is to improve the lighting conditions in libraries by implementing efficient and controlled daylighting systems. The research methodology used was a mixed-method approach that included quantitative assessments using questionnaires (n=168) for data collection and case studies of selected university libraries in Nigeria. The study examines current design approaches, daylight availability, and occupant responses. The findings revealed that it is more favourable to consider the use of passive daylighting techniques for library design as a natural way of lighting to create a pleasant environment in libraries and incorporate them into various types of libraries in Nigeria. This would improve users’ comfort, reduce the usage of artificial lighting, and increase the energy efficiency of library buildings. The significant of this study is that the outcome would provide appropriate guidance for architectural design decisions and regulatory frameworks that promote daylight-responsive library architecture in Nigerian universities.</p>
