“…Sun shading bars sunlight from directly entering the room. The shade is also used as an aesthetic element in the building to block the incoming heat due to sunlight (Purnama 2020). The horizontal Sun Shading Device is more effective in the ITDC Office Tower Semarang Design.…”

Energy efficiency is important in saving energy needs and reducing budget funds for hospital operations. There needs to be an effort to save energy using renewable solar energy sources. This study aimed to determine the optimal energy gain, the Break Event Point value, and the PV efficiency on the facade and roof of the RSUP Trauma Center NTB. It was conducted using a simulation method with the Rhino Grasshopper application and Open Studio Sketchup. It also involved collecting data and creating 3D input models into the Grasshopper and Open Studio plugin. The next stage was simulating OTTV, Cooling Load, and Photovoltaic in the test room within a year. The optimal PV shading based on the simulation was applied to the facade of the Trauma Center building. The results showed that laying PV on the roof would be more effective within 20 years than on the façade. This is because the efficiency value on the roof is higher than on the facade. The PV system measuring at a distance of 0.8 m on the facade and roof is 4.21% and 8.82% efficient, respectively. The efficiency at a distance of 1 m on the façade and roof is 6.31% and 7.81%, respectively.

“…This will certainly affect energy use in buildings. In terms of heat transfer, massive materials will be better for blocking heat from sunlight because heat only moves by conduction [3]. For glass materials, heat transfer occurs by conduction and radiation so that the loss due to heat entering the building is greater than the massive field.…”

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.
