Computation Layer
A submetering computation layer is the software tier that sits between physical meters and the systems that consume their data — BMS, ERP, sustainability platform, and tenant-billing engine. On its own, a meter is just a counter. The computation layer turns counters into decision-ready data.
Why Submetering Fails
When a 200A CT is installed on a circuit pulling 240A during motor inrush, the CT saturates and under-reports kW for the entire peak interval. The single biggest cause of unexplained variance between submeter totals and utility bills.
Low-cost wireless sensors measuring current only assume fixed voltage and unity power factor. With VFDs, welders, and induction loads, true power can be 15–25% lower than calculated, producing chronically inflated kWh reports.
BMS-driven submeter trends polled at 5–15 minute intervals miss 7-second compressor cycles and 90-second peak-demand spikes. The most expensive events on your bill are invisible without streaming sub-minute resolution.
After panel additions or controller swaps, two devices sharing the same address cause the BMS to log whichever answers first. The computation layer fingerprints each device and alerts on duplicates.
Cumulative kWh registers occasionally roll over, reset after firmware updates, or report stale values across midnight boundaries. Without rollover-aware logic, a single bad interval becomes a tenant invoice dispute.
Savings Mechanisms
Multi-site manufacturers consistently capture meaningful savings once a real-time computation layer surfaces the events that traditional reports hide.
Exposes 15-minute peaks driving demand charges, which represent 30–50% of the industrial bill.
Night and weekend baselines reveal a 20–30% leak load hidden in normal operating data.
kW/ton monitoring typically lifts coefficient of performance by 10–18%.
