Starting point
You have no monitoring yet
Twelve invoices and a main incomer. It is the most common starting point in the region, and it is enough to begin.
What can bills alone support?
| Data | Can show | Cannot show |
|---|---|---|
| Monthly bills | A whole-building baseline against weather and activity; a first carbon figure. | Out-of-hours load, plant attribution or a sub-load split. Monthly totals hide them. |
| Interval main meter | The occupied and unoccupied split, and weekend profiles. | Which plant is responsible. |
An interval read on the main incomer, from the supplier or one logger, turns the biggest blind spot on the site into a measurement. It is usually the first instrument worth adding.
What does one interval read add?
The split between occupied and unoccupied hours. It needs one read at the main switchboard, and an invoice can never give it up, because unoccupied use is folded into every monthly total.
What is the staged path?
Each stage is useful alone and you can stop after any of them.

Main incomer to interval data
From the supplier, or one logger.
- 3
Instrument where it points
Meters on the loads the evidence implicates.
- 4
Verify each change
Measured against the baseline it was modelled from.
