Study of Shading Types in Heat Transfer Calculation in High-Rise Building

Tall buildings require a lot of energy in their use. The energy needed is mainly for thermal comfort in the buildings. The heat gained by the building comes from solar radiation. Nowadays many tall buildings use translucent materials. This definitely increases the heat gain that enters the building. Shading is used to reduce the heat that hits the translucent facade. Calculations are needed to see the effectiveness of shading. the purpose of this study is to analyze the effectiveness of using shading in OTTV calculations. The method used is a quantitative approach. A quantitative approach is used. The result is that horizontal shading only reduces heat gain by 20 percent. Vertical shading is able to reduce heat gain by 25 percent on the north and south sides. Vertical shading is more effective because it can handle lower angle sunlight. a combination of both shading is needed to be able to get a smaller multiplier number so that the calculation results meet the standards.
