The efficient production does not only lie in well-thought-out processes. The energy consumption of the factories is essential, the keyword being: "smart buildings". Siemens and Mercedes-Benz have therefore developed a digital energy twin. It is supposed to enable factories to be planned sustainably.

How does it work? Based on behavioral models of buildings, technical facilities, and energy generation facilities, the energy twin links information: such as weather data, load profile simulation, plant selection and dimensioning. In this way, planners can visualize, analyze, and sustainably optimize energy building processes.

By simulating a physical energy system, the software verifies proposed energy consumption planning scenarios and suggests optimizations - including energy efficiency, cost savings, and emission reduction. Matthias Rebellius, Member of the Board of Siemens AG and CEO of Smart Infrastructure, sees the energy twin as "an exciting first step towards an integrated process for optimized planning, building operation, and production".

In practical application, the "Digital Energy Twin" is intended to help Mercedes-Benz operate all production sites worldwide completely with renewable energies by the year 2039. The car manufacturer has developed and tested the tool in Factory 56 at the Sindelfingen plant.

Halve CO₂ emissions

The software is based on the company's "Xcelerator" platform. Siemens is currently working with another partner on a similar project. In this case, an energy twin simulates the energy consumption and calculates the potential savings for 15 breweries worldwide. Siemens estimates the potential at each site to be between 15 and 20 percent. CO₂ emissions could be halved on average.

Energy twin for the automotive industry

Siemens intends to develop the energy twin as a scalable tool "for the automotive industry environment." Siemens provides training and support services for the digital energy twin and is responsible for maintenance and further development so that it can be used throughout Mercedes-Benz's global production network. Siemens and Mercedes-Benz have been working together since 2021 to develop digital, sustainable production methods.
