Smart solutions for sustainable urban energy
German state-owned energy supplier Stadtwerke Stuttgart GmbH has been working to make its facilities run more smoothly and efficiently with the help of Siemens Smart Infrastructure.
After 18 months of collaborative planning and implementation, the new Stadtwerke Stuttgart headquarters have recently opened, bringing together Siemens’ expertise in sustainable infrastructure development with Stadtwerke Stuttgart’s experience in renewable energy generation and supply.
The new facility uses an intelligent energy management system across its office complex, warehouse and workshop, which is controlled by applications from Siemens’ open digital business platform, Siemens Xcelerator. This system has been designed to optimally connect the supply of, and demand for, renewable energy for everything from heating and lighting to elevators and office equipment. It also electrifies the facility’s mobility hub, which will be used to charge electric vehicles from the Stadtwerke Stuttgart fleet.
The two companies will partner in a similar way on other Stadtwerke Stuttgart projects, including a hydrogen production facility in the city’s port.
“The combination of Siemens’ expertise in building management and ours in the energy industry creates solutions that not only help us to achieve our own sustainability goals but also help us to support other organisations in their energy transition,” said Peter Drausnigg, Technical Managing Director at Stadtwerke Stuttgart.
“We see ourselves as the driving force behind the energy transition in Stuttgart and are proud to be working with Siemens to set an example for other businesses and cities to follow around the world.”
The basis of Siemens’ building management system is intelligent digital twin technology. This means that Siemens Smart Infrastructure Building X 360° Viewer and Energy Manager offer digital representations of the headquarters, using artificial intelligence (AI) to retrieve and process relevant real-time data from installed building and e-mobility technology. Building X is a digital building platform that enables customers to digitalise, manage and optimise their building operations.
The AI system includes Internet of Things (IoT) sensors for lighting control as well as fire protection and security applications. According to Siemens, the insights produced by the AI will help to achieve energy savings of up to 30%. Such insights enable 24/7 transparency of live and historical events and generate up to 10% more net operating income, the company added.
For example, in the mobility hub, electric vehicle charging is optimised to maximise available renewable energy and, by using intelligent insights on working patterns, charging is timed to be complete for when each employee finishes work.
“We are delighted to be working in partnership with Stadtwerke Stuttgart to show how we can combine the real and the digital worlds to drive genuine sustainable transformation,” said Matthias Rebellius, Managing Board Member of Siemens AG and CEO of Smart Infrastructure.
Rebellius said that intelligent building and energy management optimises the use of renewable energy sources, maximising efficient operations while minimising impact on the energy grid. “This is setting a new standard not only in Stuttgart but for cities across the world which are facing the challenge of making both new and existing buildings fit for purpose as we collectively transition towards a more sustainable future,” he said.
