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.
