Abstract

The impact of ratio of window area to floor area rule of thumb on the performance ofday lighting was investigated using computer simulation by Radiance in IES <VE>. The purpose of this research is to find simple formulate based on window area to floor area ratio for small classroom located in Malaysia and asses the influence of variables design on their day lighting and energy consumption. The simulation was carried out for various window areas to floor area percentage in two models of classrooms. Majority of architects prefer to use the quick reference resources instead of simulation tool to evaluate the amount of day lighting. Comparative simulation were done to determine which ratio of glazing area to floor area have optimum result on visual comfort and energy consumption. In addition, correlation between results of average illuminance on size of the window to find a new rule of thumb formulate in Malyasia. This simple formulate can help architect to calculate the optimum size of window to develop day lighting in small classrooms.
