Assessment on Accuracy of Design Science Research (DSR) Framework as a Daylighting Measurement Tool for Islamic Religious School

Daylight efficiency correlates to window design. Standards and guidelines recommended 20% window to floor ratio (WFR) at 800mm to 900mm windowsill height for classrooms, where it should provide the recommended illuminance level between 300 lx to 500 lx measured at working plane height (WPH) between 800mm to 900mm. Instead, Islamic religious schools use 'rehal' at 300mm WPH. Since that the WPH is lower, the measured illuminance level is at different intensity. This paper assesses the accuracy of Design Science Research (DSR) methodology framework adaptation in measuring and designing daylight consideration in Islamic religious schools that uses lower working plane height.
