Siemens unveils autonomous building tech at Frankfurt fair

Siemens has outlined a product and software line-up aimed at building operators looking to move from conventional smart building management to more autonomous operation, with a focus on energy use, maintenance, and occupant experience.

It plans to present the approach at the Light + Building trade fair in Frankfurt, framing the shift as a response to common challenges in commercial buildings and campuses, including workforce shortages, ageing systems, and changing expectations around energy efficiency and asset values.

Siemens links autonomous buildings to a broader change in how buildings are planned, operated, and maintained, pointing to use cases in healthcare, data centres, life sciences, commercial real estate, and higher education.

Susanne Seitz, CEO Siemens Smart Infrastructure Buildings, said the shift aligns with customers operational and sustainability agendas.

"The shift toward human-centric autonomous buildings is crucial for our customers, who are looking for more efficient and more sustainable ways to operate", said Susanne Seitz, CEO Siemens Smart Infrastructure Buildings.

Autonomous operations

Siemens defines autonomous buildings as systems that anticipate demand, optimise performance and maintenance, and respond to changing conditions over time. It says people remain in control, even as automation increases.

The concept is built on a foundation that combines building systems, power distribution, and software. Siemens is emphasising integration across the building lifecycle, from design and installation to daily operations and upgrades.

A central element is Building X, Siemens, digital platform for building operations. It is designed to provide operators with a single interface for energy management, comfort, safety, and maintenance, supporting data-driven decisions and a consistent view of performance across sites.

Siemens is also highlighting Desigo CC, a building management platform that integrates multiple building systems, including HVAC, lighting, energy, and safety. It is positioned as scalable and suited to complex sites where different generations of equipment and multiple subsystems must work together.

Desigo CC uses an open architecture and includes backward compatibility, according to Siemens, targeting operators modernising existing buildings without replacing every component. Siemens says this approach improves transparency, operational efficiency, and resilience.

Electrification focus

Electrification is another major theme. Siemens is promoting intelligent power distribution systems, components, and IoT-based monitoring as the electrical layer for autonomous building strategies.

These systems are intended to provide visibility into energy flows and support more resilient distribution. Siemens ties this to the growing complexity of building energy systems, including more varied loads and closer interaction with wider grids and on-site generation.

Siemens is also positioning digital planning as part of the same shift. It is presenting SIMARIS, including its BIM plug-in, as a toolset for electrical design, aligning with the use of building information models in construction and retrofit projects for coordination and documentation.

On the hardware side, Siemens says it will show intelligent components such as SENTRON ECPD and SIVACON 8PS busbar trunking systems. It describes these as power distribution products associated with flexible distribution architectures in large buildings and industrial environments.

Automation module

For smaller applications, Siemens plans to introduce LOGO! 9, the next generation of its LOGO! logic module family. It says LOGO! 9 is designed for engineering and operations tasks in smaller-scale automation projects.

Siemens lists higher program capacity, expanded input and output scalability, improved on-device diagnostics, and secure connectivity among the changes. It says the product supports faster implementation of control and monitoring tasks and greater flexibility in deployment.

Siemens is presenting these elements as building blocks that can be deployed across different building types. It is also linking the stack to long-term asset value, framing energy performance and reliability as factors in investment and operating decisions.

Business context

Siemens Smart Infrastructure is headquartered in Zug, Switzerland, and reported around 79,400 employees worldwide as of the end of September 2025. Siemens Group reported revenue of $8.9 billion and net income of $0.4 billion for fiscal 2025, and said it employed around 318,000 people worldwide on a continuing operations basis at the same point.

At the trade fair, Siemens plans to show an integrated portfolio spanning software, building management, electrification, and automation, emphasising how the pieces connect across planning, operations, and upgrades.

"Technological advancements in buildings make it possible to reduce complexity, increase resilience, and deliver measurable outcomes. By investing in digitalization and AI, building owners have the intelligence needed to operate buildings more autonomously, while keeping people at the center." said Seitz.
