Keep your BMS. Add what it cannot see.
If your BMS works, keep it. Aqueduct reads its points over BACnet or Modbus, adds the water, energy and air metering most BMS installations never had, and works across it.
What stays and what is added.
| Your BMS keeps | Aqueduct adds | |
|---|---|---|
| Equipment | Sequences, schedules and alarms | Diagnosis of which component failed, routed to your CMMS |
| Metering | The points it already reads | Sub-meters for water, electricity and gas, and air sensors per zone |
| Results | Trend logs | Weather-normalized baselines and savings in money |
Four steps, no rip and replace.
Survey
Map the BMS points, existing meters and the gaps.
Connect
Read BMS points over BACnet or Modbus through a field device network controller.
Fill gaps
Add LoRaWAN meters and sensors where the BMS has no data, installed through partners.
Act
Faults go to your CMMS. Setpoint and schedule changes run where control is enabled, with owner approval.

If the BMS is out of support, its controllers can no longer be programmed, or it cannot share its data over an open protocol, compare the cost of keeping it with replacing it.

Common questions
No. The BMS keeps running its sequences, schedules and alarms, and Aqueduct only reads its points until the owner turns control on for specific equipment. Even then, every command is logged with whether it executed. See trust and security.
Usually a field device network controller that reads BMS points over BACnet or Modbus. LoRaWAN meters and air sensors then fill the gaps where the BMS has no data. Existing meters join if they send telemetry, so nothing that works is replaced. See controllers and actuators.
Brand matters less than access. Aqueduct works with any BMS that exposes its controllers over BACnet or Modbus, and the site survey confirms which points can be read before anything is installed. See the protocols Aqueduct speaks.
Yes. Aqueduct compares what each air handler or rooftop unit was commanded to do with what its BMS points report, then names the failed component and sends a work order to your CMMS. The BMS alarm list stays as it is. See fault detection and diagnostics.
