Optimizing Natural Lighting to Reduce Discomfort and Mobility Issues in Schools for Visually Impaired Children, Bangladesh

Abstract

Proper natural lighting is essential for developing comfortable learning environments, especially for visually impaired children. It develops general comfort and spatial awareness and lowers visual strain. However, typical schools in Bangladesh frequently lack proper lighting solutions. While improper lighting makes the learning process difficult for normally sighted children, the impact for visually challenged students is much worse as it directly affects their mobility training. The study assesses existing lighting conditions in a typical classroom of the existing modular school building and offers practical design interventions like strategic window placement or shading screens. Problems are identified by simulating the lighting condition through high-fidelity software, and practical modifications are suggested based on simulating each design intervention. The findings will guide architects, educators, and policymakers in developing inclusive learning settings. This study emphasizes the importance of well-designed natural lighting in improving educational outcomes for visually impaired children in Bangladesh.
