This master thesis presents the development of a software module that enables the import of Industry Foundation Classes (IFC) data into an existing system. The software aims to enhance interoperability, simplify the codebase, and improve performance within the building design industry. The project focuses on updating the import phase and content processing phase of the existing system, specifically targeting the EC700 software. The EC700 software, developed by Edilclima, is used for calculating the energy performance of buildings and performing related operations such as analysis, certification, and compliance verification. To achieve the desired improvements, the migration process involves integrating the ODA IFC SDK library, provided by the Open Design Alliance.
