Siemens and Mercedes-Benz have created a ‘Digital Energy Twin’ to improve the integration of energy efficiency and sustainability measures in factory designs and upgrades.

The Digital Energy Twin reduces early phase planning time significantly and has been developed developed and tested in the Mercedes-Benz ‘Factory 56’ in Sindelfingen, Germany.

The digital energy twin  is designed to support the ambition to run all fully owned production sites of the automaker worldwide on 100 percent renewable energies by 2039. Using the tool simplifies and speeds up the early phase factory energy planning process for both brownfield and greenfield sites, reducing planning time significantly. 

Siemens will provide training and support, maintain and continuously develop the tool as it rolls out across the Mercedes-Benz global production network. 

The digital energy twin is based on behavioural models of buildings, technical equipment and energy generation, taking in weather data, load profile simulation, building asset selection and dimensioning. By simulating a physical energy system it verifies proposed planning scenarios for energy usage, providing recommendations on how to optimize desired outcomes including energy efficiency and associated cost savings, as well as emission reduction.

“By accurately modelling operational and energy usage scenarios, the Digital Energy Twin enables faster and more transparent decision making in the early planning phases,” said Matthias Rebellius, Member of the Managing Board of Siemens AG and CEO of Smart Infrastructure. “This demonstrates how at Siemens we are combining the real and digital worlds to drive scalable, sustainable progress in industries, and represents an exciting first step towards an integrated process for optimized planning, building operation, and production.”

“The Digital Energy Twin is our answer to successfully visualize, analyze and sustainably optimize energy-efficient building processes. Through this innovative approach, we benefit from a better understanding of existing factory buildings and transform them into living smart buildings. Thanks to this transformative technology, we are maximizing their potential and setting forward-looking standards for energy-efficient and sustainable building use in Mercedes-Benz’s global production network” said Arno van der Merwe, Vice President Production Planning Mercedes Benz Cars.
