A university campus operates a BACnet-based building management system that was installed eight years ago and does not support OpenADR natively. The campus wants to join the local demand response programme without losing the existing BMS investment. Three options have been proposed: a gateway that translates OpenADR to BACnet, full replacement of the BMS with a newer OpenADR-capable system, or manual response by a staff member for each event. The option that best balances cost, reliability, and future flexibility is:

Question

Accepted Answer

A gateway that translates OpenADR to BACnet, because the existing BMS investment is preserved while automated response is added at a low capital cost.

Answer

Manual response, because a human operator can apply judgement and produce more consistent reductions than any automated demand response system.

Answer

Full BMS replacement, because only a complete rebuild of the building automation stack can guarantee acceptable long-term performance across all subsystems.

Answer

No participation, because a BACnet-era BMS cannot be integrated with any current demand response programme under existing standards.
