OPTIMIZING NATURAL LIGHTING TO REDUCE DISCOMFORT AND MOBILITY ISSUES IN SCHOOLS FOR VISUALLY IMPAIRED CHILDREN, BANGLADESH

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