The programming errors in Building Automation and Control Systems (BACS) control functions can lead to suboptimal building functioning. The implementation of an automatic control function presents a promising solution for error reduction. The building construction industry benefits from Building Information Modeling (BIM) for digital project work, while this method remains underutilized for BACS control function implementation. Building Information Modeling lacks clarity in its representation of control systems. An automation method for BIM control documentation alongside automated control deployment tools enables more straightforward BAS control implementations which leads to improved building operations. The MODI method establishes a systematic procedure for building energy system control algorithms with mode-based approaches which demonstrates its capacity for digitized building automation system planning and implementation. The paper presents a documentation method for storing mode-based control algorithms in Industrial Foundation Class (IFC) to facilitate data exchange between BIM while detailing a software tool for automated PLC code generation. A real case study showcases methods for documenting the implementation of desired mode-based controls for energy supply networks. The paper adopts two methods, which are IFC-based mode documentation alongside PLC programming of this strategy. The functionalities of the PLC program are verified by testing the implemented control strategy in the simulation phase. The experimental results demonstrate how mode-based control methods become agile when IFC data is applied to create complete PLC program designs.
