FAQ

BMS & Controls — frequently asked

What's the typical payback on a BMS retrofit?

For a poorly controlled HVAC or refrigeration plant, advanced controls and analytics typically save 10–30% energy with 1.5–3 year payback — often self-financed via ESCO shared-savings.

Which BMS protocols should I specify?

BACnet/IP for HVAC, Modbus TCP or CANbus for refrigeration racks, and MQTT or OPC-UA for cloud integration. Avoid closed proprietary stacks that lock you in.

Do you cover GMP / 21 CFR Part 11 monitoring?

Yes — for pharmaceutical cold chain and vaccine storage we spec validated monitoring with electronic signatures, audit trails and IQ/OQ/PQ documentation.

How does ColdMatch procure BMS?

We brief 3–5 systems integrators with a structured points list, protocol map and cyber-security requirements, then benchmark quotes on functionality, integration risk and lifecycle cost.
