TwinWorX: Simulate before Write

The Riskiest Moment for AI in a Building Isn't the Insight. It's the Write.

Analytics can find savings all day long. The hard part comes when someone has to change a setpoint, a sequence or a schedule on a live building. Most operators are left with two options: make the change and hope, or leave it alone and leave the savings on the table. Neither one builds the trust that AI needs before it can act on building controls.

Simulate Before Write is designed to change that. Built on e-Magic's TwinWorX, the workflow checks every proposed change against engineering limits. It then simulates the change against the building's own operating history and has a named person approve it. The change is written inside the BAS safety limits and watched afterwards, with automatic rollback. Life-safety systems stay read-only, and interlocks stay with the BAS.

Take an air handling unit where the request is to raise supply air from 12.8 °C to 14 °C. Warmer supply air means each zone needs more airflow. The simulation shows that one zone can't hold setpoint, so the change stops before anything is written. The building avoids a comfort complaint, and nobody has to guess.

This is the next step in Governed Autonomy: AI earns the right to act one change at a time, with evidence, approval and an undo path at each step. Know the effect before you change the building.
