The BMS replacement buyer's guide: keep it, replace it or build it in
The BMS replacement buyer's guide is a free Milvian AI guide for teams deciding what to do with an aging or underused building management system. It sets out the three ways in, keep your BMS, replace it or build Aqueduct in at design stage, and the questions to ask on protocols, control with owner approval, CMMS integration, security and cutover.

Consider replacement when controllers are end of life, parts or support are gone, the system cannot share data, or it is so underused that nobody acts on what it shows. If it runs well, keeping it and adding an intelligence layer is often the better first step.
Aqueduct can replace or work across a BMS, BAS or EMS. It monitors equipment and, where control is enabled with owner approval, sends schedules and setpoints through BACnet or Modbus field devices or LoRaWAN relay switches. Scope is confirmed per site in the survey.
No. Keeping your BMS is one of three ways in. Aqueduct reads BMS points alongside meters and sensors, and pulse splitters let existing systems keep receiving meter data.
Two ways: LoRaWAN relay switches for simple on and off loads such as fans, and a field device network controller that speaks BACnet or Modbus to AHUs, RTUs, chillers and VAV boxes. Lockouts protect equipment from short cycling, and every command is logged.
No. Aqueduct integrates with your CMMS and routes work into it with evidence and a recommended fix. Technicians, inventory and work order workflows stay in the CMMS.
