The study investigates the use of local trees in the UAE to improve visual performance and lighting quality in typical classrooms. The methodology depended on analysis of luminance ratios and illuminance levels using simulation (Radiance.) The effect of two design variables (i.e., tree type: Ghaf and Neem, and tree spacing: 2m and 4m parallel to outside north wall, on task’s illuminance levels and interior-surfaces’ luminance levels were investigated. Lighting quality and visual comfort issues such as acute contrast, high brightness, and daylight distribution were discussed.
