Sample report

What a report looks like

See the kind of results the analyser produces before you find your own meter data. This is a made-up office with made-up readings.

Made-up example. The office and its meter readings are invented, so nothing here is a real customer's result. Every figure is what the analyser reports for our example file, at an illustrative 25p/kWh.

This made-up office used 79,191 kWh of electricity in a year, costing about £19,798 at 25p/kWh. A third of it (33%) was used while the office was closed. Use above the base load during those closed hours costs about £2,776 a year, almost half of it on Saturdays.

What the analyser found

High impact

Use while closed

£2,776 a year

11,035 kWh used outside opening hours, above the base load. Almost half of it (5,155 kWh) is on Saturdays; weekday evenings and nights add 3,750 kWh.

What to check: whether the office is used on Saturdays, and the heating and ventilation schedules.

Medium impact

Bank holidays like working days

7 bank holidays

Seven bank holidays, including Christmas Day, used at least 80% of a normal weekday's electricity (1,408 kWh above base load in all).

What to check: whether the building controls know about bank holidays.

Already included in the £2,776.

Low impact

Early starts and late finishes

£629 a year

About 1,250 kWh above base load in the two hours before opening, and the same again in the two hours after closing.

What to check: timer and heating start-up settings.

Already included in the £2,776.

The smaller findings are parts of the £2,776, not extra to it, so don't add them up. The base load is separate: 2.6 kW running all year costs about £5,700.

What could actually be saved?

The figures above are what each pattern costs now. They are not a promised saving. What you save depends on what you change, and some of that closed-hours use may turn out to be needed, such as a regular Saturday team. The way to find out is to:

  1. Confirm the opening hours. If Saturdays are planned working days, much of the £2,776 is normal use.
  2. Walk round the building on a Saturday and after closing time, and note what's switched on.
  3. Change one setting at a time, such as the heating schedule or bank holiday calendar.
  4. Compare the weeks before and after with the analyser's before-and-after view. That gives you a measured saving rather than an estimate.
