BuildingTwin - Open Platform for Monitoring, Evaluation and Optimization of Building Operation

Keeping track of all data about a building over its entire life cycle is a major challenge. Planning data, like the building information modeling (BIM) data, is often not carried over into the operational phase. The "as-built" state is commonly documented in various lists and data sheets, independently of the BIM model. And usually neither real-time nor historical data on the operating status of the building is available. This lack of data makes it hard to operate a building in an optimized and efficient manner. We demonstrate the web-based platform "buildingTwin" to aggregate all building relevant data in a centralized "digital twin" model of the building, combining BIM data from the planning phase, data sheets and attributes documenting the "as-built" state, and real-time measurements from sensors and other sources during the operational phase. This platform provides easy access to all building data and enables monitoring, evaluation, and optimization of the building operation.
