Abstract: Shading device, window to wall ratio, window height, and glazing are important factors in determining building energy consumption in the tropics. This study employed the four factors in designing energy-efficient window for classroom to reduce the energy consumption for supplemented lighting and mechanical ventilation. The method was based on Ecotect simulations under some parameters, i.e. heat gains through the building fabrics, illuminance level, and daylight factor. This study concluded that projected clerestory is the most energy-efficient window design. It should be applied on classroom with considering the Window to Wall Ratio, the clerestory height to room height ratio, the window to floor area ratio, and using low visible transmittance of the view window glazing to achieve even horizontal daylight distribution.
