Cut energy costs, reduce downtime, and meet sustainability goals — see how Siemens Building X makes it possible through building digitalization.
Frida Ahlberg from Siemens explores how Building X enables sustainable, energy-efficient building operations through AI and digitalization at Nordbygg 2026.
The presentation opens by broadening the definition of sustainability in building operations — encompassing not only CO2 reduction and energy efficiency, but also minimizing unplanned downtime and avoiding premature equipment replacement. Frida challenges the assumption that buildings are running well without digitalization, highlighting the hidden costs embedded in fragmented data, multiple disconnected systems, unnecessary site visits, and inefficient information management across facility teams.
Building X is introduced as a vendor-agnostic, open cloud platform that connects all building systems and assets — regardless of manufacturer — into a single, standardized data environment. The platform accepts data from third-party BMS systems, OT sensors, and other sources, enabling a consolidated view across an entire building portfolio without requiring hardware replacement.
The session outlines a structured path toward the autonomous building, covering key capability areas including smart-from-the-start design using BIM to establish asset data from the construction phase, live sensor data connectivity across all building systems, and predictive maintenance powered by AI-based Smart Diagnostics. This feature automatically identifies faults and probable root causes, providing technicians with context and prioritized action plans — a significant step beyond traditional alarm-based BMS notifications.
Also demonstrated is AI-driven autonomous optimization of HVAC and heating systems, which runs continuously every ten minutes using historical data and forecasting inputs. The Sustainability Manager application is shown as a practical entry point for energy monitoring, cost visualization, and emissions tracking across a building portfolio, including decarbonization planning aligned with global climate frameworks such as those referenced under the EU Energy Performance of Buildings Directive.
A live platform demo shows how facility managers and technicians can navigate standardized asset data, query the platform using natural language to generate fault summaries and action plans, and monitor energy and emissions compliance — all within a single interface.
