The bulk of research on the performance of double skin facade is carried out in moderate climates with concern to ventilation and thermal performance. Day-light performance of double skin facades in hot aarid zones is still under scientific scrutiny, which will be the concern of the research in Educational Buildings. This investigation adopts an inductive method using comparative analytical approach to convert general intuitions on the daylight performance of a double skin facade, in hot arid areas, into the grounds of understanding its performance based on research. Based on two case studies of lecture halls; the first with Single Skin Façade (SSF) and the second with Double Skin Façade (DSF); the impact of double skin façade on lighting performance is examined. The Protocol was applied to south facing models under overcast sky conditions and was implemented under different outdoor luminance to test significant effects to indoor illumance values inside the lecture halls. Simulation results indicate that a double skin facade can achieve high lighting performance with better energy savings than a single skin façade; also the basic characteristics of width and distance of two walls are examined. It was expected that DSF fail to meet the acceptable standard indoor illuminance requirement of 200 to 300 lux within 75% of the lecture halls. Comparing the single and double skin facade, the percentage of the lecture hall covered with acceptable illumination level of 200 to 300 lux are found in the range of 30%, 80% respectively.
