The efforts to revitalize the U-value simulation of a window set are recently increasing. However, despite this prospect, the current input of information required for the simulation is performed manually. Therefore, this study proposed a method to extract the geometry information from the window set BIM automatically. In order to achieve the goal of the study, first, the geometry information required by the U-value simulation of a window set is defined. Second, a method is proposed to extract the geometry information from the window set BIM. Third, a method is proposed to convert the geometry information which is extracted from the IFC file into the THMX file. Finally, a pilot test is performed to verify productivity and reliability of the proposed method. Since the geometry information required for the U-value simulation through the proposed method can be entered automatically, the productivity of the simulation can be increased. Besides, since errors of a geometry are not occurred in the process of the frame modeling of a window set, it is expected to improve reliability of the results of the simulation.
