Ken Sinclair: Natural Language: The Semantic Interface for the Digital Twin

​ Ken Sinclair

Natural Language (NL) processing, powered by AI, fundamentally augments the building’s ecosystem in three major ways: Access, Abstraction, and Action.

1. NL Provides Universal Access (The “Interface”)

NL tears down the technical barrier between the operator/occupant and the complex technical data.

  • Replacing the Dashboard: Instead of navigating complex dashboards, menus, and proprietary interfaces, operators and facility managers can ask questions using plain language: “What is the average energy consumption of the chillers this week?” or “Find all zones running past the occupancy schedule.”
  • Empowering Occupants: Occupants gain simple access to controls: “It’s too cold in conference room B,” or “Please turn the lights down 10% in the West wing.” The system then translates this NL into the necessary machine command.
  • Facilitating Search: NL enables precise, efficient data retrieval across the building’s semantic model (the colourful blocks). You don’t need to know the BACnet object ID; you ask, “Show me the maintenance records for the fan located on the third floor near the cafeteria.”
