Siemens & AUDI AG – Digital building technology: Control system recognizes potentials in plant operation

The topic of this podcast episode is today’s building technology and how digitalization and IoT technology are sustainably changing plant availability as well as energy and cost efficiency and creating synergies across trades. The focus of the concrete use case is the Audi site in Neckarsulm near Heilbronn with its approximately 70 buildings covering an area of over one million square meters. Production buildings, paint shops, body shops, assembly, as well as administrative and office buildings are turned into smart buildings with the help of Siemens Smart Infrastructure and Audi master of 70,000 data points. The focus of this podcast is on ventilation systems. What are the tasks of such a site? It is about ensuring the supply of energy and media in the right quality and quantity. The provision of electricity, water, air, cooling and gases must be carried out in accordance with applicable laws and guidelines and in the spirit of economic efficiency and sustainability. It is about monitoring plants, ensuring security of supply and identifying potential. Production control technology and building control technology are already being linked together today. The plant is controlled depending on the production. Deviations from standards with regard to maintenance, user behavior or energy efficiency can be detected using an optimized digital twin. It also works with a web-based cloud platform that has both an import and export interface. On the one hand, a wide variety of trades and data can be imported, and on the other hand, the data can be clearly visualized and evaluated and optimized with the help of data analysis and montoring. The key to success here is the constantly growing set of control parameters and algorithms for error analysis and efficiency optimization, which Siemens is expanding across customers. The focus is not only on the individual device, but on the entire system functionality of the many complex individual devices and their holistic monitoring.
