Abstract
Illuminance is an important measure of the quantity of light falling on a surface especially in learning spaces. Design block windows are fast becoming a common window choice for schools as it is cheaper to maintain and provides more security. Scanty or no information exists on classroom illuminance for this window type especially for public basic schools.This research examined the illuminance in classrooms with design block windows per existing standards of classroom illuminance. Classrooms were measured and mapped into a variety of environmental variables and illuminance measurements taken using lux metres(LX 1330B) with only daylight at 0.72m from floor level with four parameters. Fourty percent of the classrooms studied had at any test time/condition, the recommended amount of lighting of 300-500 lux whiles 60 percent were either below or above this range. The study concluded that, more attention has to be given to the development and enhancement of passive daylighting through alternative ventilation systems like design block windows which can stay open in all conditions and under any weather.
