SpotCool AI is an agent that sits on top of an office building's existing CCTV and BACnet BMS, with no new hardware. Every 15 minutes it sends each zone camera's snapshot to Meta's SAM 3.1 to see whether people are there. Empty zones ease off to 28 °C, occupied zones go back to the building's normal control, and booked rooms are pre-cooled. In the meeting room, the AC's louvers follow the person SAM sees. Muse Spark reads clothing and activity to set a comfortable temperature, and spoken complaints ("it's freezing") adjust it through Muse Voice and Muse Wonder. The operator always wins: the agent writes at a low BACnet priority and backs off from any manual override. On a full simulated office day in BOPTEST, SpotCool used 19.94 % less HVAC energy than the baseline (SAM 3.1 perception, in simulation). The comfort cost is shown alongside it: discomfort where people were rose from 0.33 to 2.13 kelvin-hours.
