Abstract
This study is regarding the application of external shading device in the low-latitude region and proposes a design method, which includes all of the design processes ranging from architecture to energy evaluation. The proposed design method of optimized external shading device is applied to an actual office building in Jakarta, Indonesia. Finally, building's annual cooling load and energy savings rate after the shading device installation have been calculated. The method of study is, (1) to identify external environmental conditions through climate analysis, (2) to set a baseline model that satisfies the basic conditions of Greenship and to analyze the cooling load, (3) to analyze annual solar gain and solar shading effects of each direction for the shading device's performance evaluation, (4) to propose optimal shading device through case study by type, (5) to provide quantitative of both analysis of the building's cooling load with the optimized shading device installed and the effect of energy savings through energy simulation.
