The Heatmap

The Heatmap makes recurring structures in your consumption visible. It shows at which times energy consistently flows at high or low levels.

Note: Like the Day Profile, the Heatmap requires at least hourly values. If a metering point only delivers daily values, we hide this page from the navigation.

How to read the Heatmap

The Heatmap arranges your consumption on two axes: weekdays from Monday to Sunday (horizontal) and hours of the day from 00:00 to 23:00 (vertical). Each cell is the average for that time slot across the selected period. The more intense the colour, the higher the consumption.

Heatmap: average consumption per weekday and hour of day, dark cells show high consumption, light cells show low consumption.
Heatmap: average consumption per weekday and hour of day, dark cells show high consumption, light cells show low consumption.
  • Light cells: low consumption, for example at night or on weekends.
  • Dark cells: high consumption, for example on weekdays during office hours.
  • Uniform columns: similar daily pattern on all days of the week.
  • High-contrast patterns: clearly defined usage times.

For feed-in meters, the Heatmap shows the fed-in energy instead of consumption.

Off-hours share

Above the Heatmap you see the KPI Off-hours share. It shows what proportion of your consumption falls outside core hours: on weekends, and on weekdays before 08:00 or from 18:00. A high share in a commercial building points to equipment running outside operating hours.

How to use the Heatmap

  • High night-time consumption: Check standby loads, hot-water storage, or heating circulation pumps. Devices running unnecessarily at night push up the base load.
  • No difference between weekdays and weekends: In commercial buildings this can indicate missing time controls for heating, ventilation, or lighting.
  • Irregular patterns: In residential buildings these are normal, as consumption follows the occupants' daily routines. In commercial buildings it is worth a closer look at operating hours.
  • The Day Profile condenses the same information into an average daily curve, split by weekday and weekend.
