The graphs below present our School’s energy consumption in two ways. The underlying data are provided by our campuses’ energy suppliers.

Energy use by month

This graph shows our energy consumption by month, versus the previous two years. The current month is not included.

Energy use by week

For each day, an average seven-day figure is calculated based on a centered moving average (from minus three to plus three days). Each point thus represents the average consumption calculated over seven days (the day in question, the previous three days and the following three days).

Figures for the current year and the previous year, as well the average of the previous five years, are shown.

High and low points over the past five years are indicated in gray.
