Smart Buildings & Facilities
AI-assisted BMS monitoring where tenant occupancy profiles, energy consumption patterns, and access events stay inside the building network. GDPR compliance for personal location data is handled by the architecture, not a data processing agreement.
The Challenge
Modern commercial buildings generate occupancy data, access control logs, and HVAC telemetry that can be linked back to individuals. GDPR treats location data as personal data when it can identify a natural person. Sending that data to a third-party cloud BMS analytics platform creates a data transfer obligation that most facilities managers and their legal teams prefer to avoid.
At the same time, facilities teams are being asked to do more with less: reduce energy consumption, respond faster to HVAC faults, and produce sustainability reports. An AI interface that can query sensor data across a full building portfolio — without a cloud intermediary — solves both problems at once.
How BunkerM Fits In
BunkerM Enterprise connects to Honeywell, Siemens Desigo CC, and Schneider EcoStruxure BMS systems via Sparkplug B or Modbus TCP bridges. Each floor zone, HVAC unit, access reader, and energy meter is registered in the local device registry with its metric names, current values, and engineering units. No data leaves the building network.
The facilities team queries the AI to get immediate answers: "Which floors in Building 7 are running above setpoint temperature?", "What is the energy consumption per square metre on Floor 3 versus Floor 4 this week?", or "Which access readers reported faults in the last 24 hours?". Reports are generated on-demand from local data, without any external API call.
A Typical Deployment
A facilities management company operates 24 commercial buildings for a financial services group. Each building runs Siemens Desigo CC as the primary BMS, with Honeywell access control layered on top. BunkerM Enterprise runs on a server in the building operations centre, aggregating telemetry from all 24 buildings over the client's private WAN. The AI interface is available via the web chat and Telegram to the on-call facilities team. Tenant energy profiles, occupancy heatmaps, and access logs are queried and reported entirely within the client's private infrastructure.
Privacy & Compliance
🔒 Tenant data stays inside the building network. Occupancy patterns, access events, and energy profiles that can be linked to individual tenants or employees are personal data under GDPR. BunkerM Enterprise processes all of this data locally. There is no transfer to a third-party processor, which removes the Article 28 data processing agreement requirement for the analytics layer entirely.
