Building Information Modeling (BIM) has advanced the construction industry from simple 2D/3D CAD to semantically rich, object-oriented, and visually intuitive modeling. However, unlike, e.g., the UML or SysML, BIM's modeling formalisms lack universal applicability and full life cycle coverage, confining its use largely to architectural design. Key trades like building control remain insufficiently integrated, leading to inefficiencies and misaligned design and operational requirements. This paper presents an ecosystem of domain-specific modeling languages (DSML) integrated with BIM, to expand its capabilities to additional trades such as building control. By embedding operational requirements (cf. the building control system installation) during the design phase by integrating them into the BIM model, the subsequent application of model-driven deployment ensures alignment with operational objectives. Validation in a Living Lab at the University of Innsbruck highlights the approach's benefits, including faster commissioning and improved energy efficiency, representing a step toward comprehensive, BIM-based building design and operation.
