Siemens tech enables successful research at Zero Carbon Building Systems Lab

Siemens technology enables new lighthouse project for climate research at ETH Zurich

The lab allows experimental research and system testing to be carried out on a 1:1 scale. Research is conducted into active and passive technologies for energy supply, automation, and climate control in buildings under a wide range of environmental conditions. It was established by the Chair of Architecture and Building Systems at ETH Zurich headed by Prof. Dr. Arno Schlueter, who has been working with Siemens for many years. “Flexibly deployable digital systems and the corresponding industry expertise are essential, both in a research environment and to put research findings into practice,” explained Schlueter.
The ZCBS Lab uses comprehensive automation solutions from Siemens Smart Infrastructure. Its digital building management system Desigo CC controls and monitors all disciplines and enables efficient building operation as well as specific research tests that can be performed under optimal conditions. The design of the Siemens solution allows the climate and building technology requirements to be adapted quickly and flexibly to the various research projects and the desired test parameters. Siemens’ system collects all important data generated by the installed sensors and field devices and transmits it to the higher-level ETH control system.
Matthias Rebellius, CEO of Siemens Smart Infrastructure, is pleased that this lighthouse project uses Siemens technology: “Our building management system lays the foundation for enhancing the existing ETH systems as needed and potentially connecting them in the future to the open digital building platform Building X, which is part of the Siemens Xcelerator portfolio.”
Siemens Xcelerator is an open digital business platform, enabling customers’ digital transformation in industry and infrastructure faster and at scale. Launched in June 2022, the platform has grown and developed continuously ever since. Together with a powerful partner ecosystem and a marketplace, Siemens Xcelerator supports companies in their digital transformation.

Proven cooperation between Siemens and ETH Zurich

The ZCBS Lab is designed to be extremely flexible not only in terms of building technology, but also in terms of layout. Individual rooms can be connected or separated as needed. This allows comparative or isolated tests of components and building systems, e. g. for efficient cooling or integrated power production using solar technology. User acceptance studies can be conducted in individual test cells. In their experiments, researchers can independently control the entire building automation down to the field level and switch from operating mode to research mode at the push of a button.
The highlight of the new ETH facility is a room with a solar emulator. This test facility makes it possible to simulate not only temperature and humidity, but also the solar effects during the course of the day. This artificial sun is based on energy-efficient LED technology and is unique in the world.
The strategic partnership between ETH Zurich and Siemens has a long tradition. Siemens has helped provide financing for the chair in Sustainable Building Technologies since 2009. This funding has enabled ETH Zurich to further expand research and teaching in the field of sustainability and energy. In addition to sustainable and digital construction, Siemens and ETH Zurich are collaborating closely on research into future mobility.
