EnergyTWIN – energy diagnostics plug digital twinCopyright: © e3D
Digitization is a megatrend in all areas of the economy and society. This is particularly true for the construction industry, which has a lot of catching up to do compared to the other sectors and is one of the least digitized industries today. From the perspective of the energy transition, digitization is a key implementation tool for managing the volatility of renewable energies in the electricity, heat and mobility sectors on the generation and consumption side. In the future, information technology solutions that capture this interplay of an increasingly complex energy system technology will have to offer far more as is currently the case. Highly complex interrelationships in technical building equipment and building automation must be captured in terms of information and communication technology and, in connection with BIM models, processed and managed in a form that is comprehensible to humans. An important factor here is the intelligent and semantic structuring of these models in a data-driven planning process.
For this purpose, the EnergyTWIN project is developing methods for the (automated) generation of a "digital twin" for the application case of the commissioning of building services engineering and its continuous update with data enrichment in the operating and use phase. Geometry, system topology as well as energetic-functional and information-technological correlations of building services installations are to be recognized in the context of the constructional implementation or technical commissioning by means of an acquisition of the as-built construction based on the execution planning data. The acquired data are to be processed for an energetic building stock optimization. The recognition and classification of components as well as the organization and structured processing of data, taking into account functional relationships, are important, overarching topics that have so far been given very little importance in the context of the digitization of the energy transition. Currently, the topics of BIM, plant schematics, building automation, CAFM and operational optimization are isolated from each other. In this project, the important megatrends of digital construction, such as the use of methods for high-resolution as-built data acquisition, new 5D BIM tools, smart asset management and the use of machine learning methods, will be linked with central topics of the digitization of the energy transition in the building sector in order to solve this shortcoming and make it economically viable. As a result,
- a structured building information model (as-built-BIM) provides information about the geometry, topology and semantics of the plant technology,
- a systems engineering piping diagram provides information about the physical system topology of the building technology, and
- a logical linkage scheme provides information about functional and information relationships between actuators and sensors.

The developed methods will be applied in the new construction project of the extension of the Debeka headquarters in Koblenz and validated in the course of commissioning and operation. The new office and administration building comprises a total of 16 floors, two of which are implemented underground and 14 above ground. This corresponds to a gross floor area of over 55.000 m2. The new building will be connected to the existing building via a single-story bridge and is scheduled to be occupied by 1,350 employees of the Debeka Group as early as 2022. The general planning of the new building project is being carried out by RKW Architektur +.
