Full speed ahead for the Stuttgart climate roadmap

Stuttgart aims to be climate-neutral by 2035, ten years earlier than required by the German Federal Climate Change Act. To achieve this goal, the municipal utility company Stadtwerke Stuttgart is implementing a sustainability concept together with Siemens, starting with its own head office.

The "Stuttgart Way" - climate neutrality by 2035

Why have we set out on this difficult route when an easier path is available? Climate-neutral by 2045, that is the legal requirement. But Stadtwerke Stuttgart has decided to take the "Stuttgart Way" with the goal of climate neutrality by 2035.

Municipal utilities and their challenge on the way to climate neutrality

Municipal utilities are the engine for the energy transition. As a general service provider for key sectors such as energy, transport and buildings, they can act as a role model by driving the energy transition. In order to achieve the climate target of the city of Stuttgart, 3.6 megatons of CO2 equivalents must be saved annually – a huge challenge for the Stadtwerke Stuttgart Group.

Technology partnership with Stadtwerke Stuttgart

The Stadtwerke Stuttgart Group is defining concrete steps to achieve these ambitious goals and is implementing a comprehensive sustainability concept together with Siemens within the framework of a technology partnership. Products, solutions and services are used in a wide range of efficiency, energy, and residential area projects. The open and interoperable Siemens Xcelerator business platform forms the basis for cross-building applications. What does that look like in concrete terms? Siemens provides the sensors and the software. We work with the energy experts at Stadtwerke Stuttgart to develop energy and heating concepts that can be integrated into customer systems based on the resulting data and functionalities.

Building X offers the following advantages for the building in Kesselstrasse

360° Viewer: Photorealistic image as a digital twin. The 360° Viewer provides a continuous overview by displaying a virtual 3D environment.

Energy Manager: The energy consumption, costs and CO2 emissions of the building are recorded and analyzed so that optimization measures can be defined at an early stage.

Operations Manager: For monitoring a wide range of building installations and applications – in real time and from a single location. This makes it possible to respond to faults faster, thus minimizing downtimes and improving business continuity.

Lifecycle Twin: Serves a central data hub. It provides end-to-end visibility and comprehensive management for technical building services and all of the building’s assets, as well as efficient work order management in a virtual environment.

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 organizations in their energy transition.”

New headquarters to become a sustainability showcase

The conversion and modernization of an existing building at Kesselstrasse 23 in Stuttgart can be seen as the reference and starting point of the technology partnership.

The first concrete measure is the modernization of the future head office of the Stadtwerke Stuttgart Group. Their new home is to become a showcase for sustainability and modern work practices. To this end, the office complex, including the warehouse and workshops at Kesselstrasse 23, is being converted and expanded according to a holistic sustainability concept. This entails, among other things, the use of renewable energy and efficient energy monitoring. The technology supplied by Siemens meets the current criteria of digitalization and sustainability, and encompasses new building and room automation, security technology and software applications. In addition, the software-as-a-service model provides Stadtwerke Stuttgart with requirement-based state-of-the-art technology that can be flexibly adapted in the course of the project.
