OTTV based shading devices optimization for multi-storey building in tropical Jakarta

Abstract

Energy conservation efforts are being carried out by countries in the world as a result of energy crisis. The efforts are carried out in various aspects including in an office building that tends to use a large amount of energy. Based on regulations from the Jakarta Green Building, the OTTV standard for the city of Jakarta is 45 W/m2. To achieve the ideal OTTV value, efforts are needed on building to meet the standards which is applying shading devices. This method of study uses quantitative methods by simulating OTTV on the building envelope using the OTTV Calculator from the Jakarta Green Building. The simulation produces an ideal and effective shading device design in reducing the value of OTTV in buildings.
