Passive design strategies play a significant part in improving the performance of retrofitting buildings. This especially applies to educational buildings that demand a high quantity of energy, not only due to various types of rooms and occupants but also operational needs of space regarding heating and cooling. Besides, the energy performance of the buildings will gradually decrease due to natural factors, such as aging and extreme weather conditions. Through retrofit design strategies, this study explores various scenarios on educational building facades by modifying shading and glazing properties. In this regard, several scenarios are proposed such as an addition of vertical fins, changing of glazing properties, and a combination of both. This study results in, first, the reduction of the Overall Thermal Transfer Value (OTTV) by 6,04 W/m2 and second, the reduction of indoor temperature by 0,835°C from the existing to a proposed combination scenario. This study ultimately enables the architects in determining the optimum retrofitted facade strategy for educational buildings in the tropical climate.
