For building, MEP and controls engineers: live twins and control you can audit
Engineers are measured on whether systems run to design: setpoints held, sequences stable, plant efficient. Aqueduct gives a live digital twin of the electrical single line and of each rooftop unit, fault findings per component, and control over BACnet and Modbus with every command on record.
Design intent is easy to draw and hard to keep.
The numbers your systems answer for
- Setpoint attainment
Share of time each unit reaches what it is asked to do.
- Sequence exceptions
How often sequences fight each other or break.
- Plant efficiency and power quality
Load, power factor and loading against rated capacity per feeder.
Engineering calls the data supports
Retune or repair
Tell a sequence problem from a failed component using per-component state.
Which strategy to enable
Pick supply air reset, static reset or demand-controlled ventilation per unit, with its guardrails.
Learn moreWhere to correct power factor
Find feeders with poor power factor or high loading on the single line.
What to meter next
Close gaps where the twin shows no data or an unexplained balance.
Engineering work, before and after
| Task | Today | With Aqueduct |
|---|---|---|
| Diagnosing a unit | Trend logs pulled from the BMS | RTU twin: damper, cooling, heating and fan states live |
| Proving a sequence change | Before and after spot checks | Savings against the unit's own baseline |
| Changing control | Edit the BMS and hope | Rules by device or zone occupancy, where control is enabled, with owner approval |
| Checking a command | Assume it executed | Command history shows whether it did |
| Electrical review | Annual power survey | Live kW, kVAR and kVA per feeder |

Two ways: LoRaWAN relay switches for simple loads, and a field device network controller speaking BACnet or Modbus for AHUs, RTUs, chillers and VAV boxes. Field devices push telemetry back, so control also enriches the data. See controllers and actuators.
Lockouts block a new command while an earlier one is still being acted on, which prevents short cycling. Commands run only on units the owner has approved, and each one is logged with whether it executed. See trust and security.
Yes. A control cluster groups devices and sensors, such as an RTU and its zone sensor, so they are operated and analyzed as one system. A pressure reading from a linked sensor can then trigger the unit's filter alert. See AI optimization.
Setpoint attainment, comfort compliance and sequence exceptions, each banded good, watch or attention, plus communication health. Engineers see at a glance which units are not running to design. See digital twins.
