Siemens Building X

Modular cloud suite for building management that brings data from installations, meters and sensors together in a single data lake. AI controls climate systems and performs real-time analysis and forecasting; Occupancy Manager proposes Eco and Comfort schedules itself based on expected occupancy. Open APIs and vendor-independent integrations, so it can also be used on top of non-Siemens hardware.

Who is Siemens Building X for?
Siemens Building X focuses on building management & installations, real estate, renewable energy & the energy transition. It suits work such as optimising heating, ventilation and climate control per zone based on usage and weather forecasts, monitoring energy consumption and automatically flagging deviations, and predictive maintenance of installations: boilers, air handling, cooling and lifts.
What should I look out for with AI in building management & installations?
Keep two things in view at once. First, privacy: occupancy, badge and booking data can often be traced back to individual employees. Measure at zone or room level, not per person, and involve the works council when introducing it, a system that records staff presence falls under article 27 of the Dutch Works Councils Act (WOR) on staff monitoring systems. Second, security: an AI layer that is allowed to control your BMS becomes part of your operational technology. Never expose that connection unsecured to the internet, work with read-only access until you trust the behaviour, and record who can intervene if the control goes wrong, in care buildings, laboratories and server rooms, a wrong setpoint can cause immediate damage. If you fall under NIS2, there are explicit requirements for supplier management and incident reporting. Also agree a data processing agreement and EU hosting with every supplier, and check energy-saving claims against your own meter data rather than the brochure.
