Building X – Leap into the future of buildings

Siemens’ approach to smart building systems centres on openness. With its Siemens Xcelerator platform, the German tech giant is moving away from proprietary lock-ins to an open digital business platform that accelerates digital transformation. Its flagship offering in this space, Building X, is a cloud-native smart building suite that acts as a‘ single source of truth’ which eliminates data silos by integrating disparate systems – regardless of vendor – into one cohesive dashboard.

“ Building X breaks down barriers,” says Matthias Rebellius, Member of the Managing Board of Siemens AG and CEO of Smart Infrastructure.“ We can now combine all data generated by systems in smart buildings into a single data pool.
This allows us to realise smart buildings faster and brings us closer to our vision of autonomous and climate-neutral buildings. Building X creates measurable data-based results regarding efficiency, performance and user experience. In this way, Building X improves how we work and live in buildings.”
Siemens focuses heavily on the‘ gridinteractive’ building, viewing buildings not just as energy consumers, but as prosumers that can store energy and feed it back to the grid. By leveraging AI to predict energy loads, Siemens helps massive commercial estates flatten their demand curves, saving millions in operational costs while stabilising the local energy grid.
