Abstract: The preliminary design of an architectural building is an essential stage to define its building performance. Not only the architectural visual and beauty, but the design process also plays an important role to obtain energy optimization. The decision of building shape, orientation as well as its material gives influence on the heating and cooling system, also controlling the lighting. It located in the tropical climate region giving the consequences on a more prolonged period of solar radiation. It provides the implications for cooling system sizing such as electric load shape, electrical demand, and it affects the using of energy. This study aims to describe and deliver the design process of the Botani Museum that use Sefaira®. Sefaira System is a software used to model to estimate its overall energy use, and determine its strengths and weaknesses in energy retention and conservation on Botani Museum. The HVAC (Heating, Ventilation, and Air Conditioning) then are common in dominating building energy use. Thus, the design responds to have optimum impact on HVAC system. The results of Sefaira simulation shows that the preliminary design of the Botani Museum is having energy unit intensity (EUI) as much as 82kWh/m2/yr. Meanwhile, the 2030 challenge of Sefaira shows the EUI is 79 kWh/m2/yr. It means that the proper design process will deliver the optimum result. The building envelope, orientation, as well as wall window ratio, are some of the architectural elements that significantly impact on energy use.
