Every month, the facility manager at a large IT park campus faced the same headache: tenants drew power from the grid, but many also depended on centralized chilled water for cooling. Two utilities, two sets of meters, and no single system that could turn both into one clean, prepaid bill. This is the story of how that changed — and stayed changed for seven years.
Commissioned in July 2018. Still running today, without interruption.

Every tenant expects a fair, accurate, real-time bill. Every finance team expects predictable revenue. And every meter on site speaks its own language. In 2018, the facility manager overseeing this campus went looking for a platform that could read both energy and thermal consumption, convert it into a prepaid balance, and manage it all from one PC-based control point. Most vendors offered half the answer. None offered the whole thing.
The result:
Inside the full case study, you'll see:
| Year | Milestone |
|---|---|
| 2018 | The facility manager's system goes live: 22 BTU meters + 55 dual-source energy meters integrated across BACnet IP and Modbus IP |
| 2018–2024 | The operator runs prepaid tenant billing across the campus without a single major interruption |
| 2025 | The system quietly completes 7+ years of continuous operation, still active today |

It was going years without needing to think about the billing system at all, because it simply did its job. That's the real measure of a system built to last: not how impressive it looks on day one, but how invisible it becomes by year seven.
