It describes a loop where EnergyPlus runs the physics, an MCP layer carries every sensor reading and command, and a local open source LLM makes control decisions, returning set points every simulated hour. Sensors are read at every zone timestamp, and with a control interval of 60 minutes the system reports metrics like PMV, cooling, and heating associated with timestamps such as 12, 13, and 14. Set points pass a validation gate and are injected into the running solver without file rewrites or restarts, closing the loop within one simulation and showing summer week energy savings on the dashboard.
