| Abstract |
Digital conversion aimed at optimizing building energy usage has progressed since several building energy modeling tools, such as EnergyPlus and TRNSYS, became widely used. These programs can be considered an early stage of digital conversion in modeling buildings digitally to simulate energy usage. For optimizing building energy consumption, green remodeling is essential for enhancing building properties through both passive and active methods. Nowadays, digital tools for designing and constructing new buildings have garnered significant interest, as working with these tools can minimize repetitive modifications during the design process, thereby reducing unwanted time and cost. Among these digital tools, the IFC-BIM platform offers distinct advantages as a common resource for advancing new green remodeling processes. It can reflect and connect various parameters and open-source data more effectively than other commercial programs. In this study, the IFC-BIM structure of the green remodeling digital platform will be explored in conjunction with digital twin technology, considering the connectivity between these two platforms in the context of reducing and managing building energy usage to achieve carbon neutrality in the building sector. |
