- This feature is available in the Total consumption, Heating, and Cooling widgets.

- This feature is available only for consumption.

- At least 12 months of consumption data are required to show valid weather-normalized values.

Weather normalization (or weather adjustment) is a process that mathematically adjusts measured consumption data to represent consumption in an average or reference year for one location. This accounts for weather differences that may result in abnormally high or low consumption. For example, if you compare two buildings in different climatic areas and find one to be less efficient, you need to have confidence that the difference was not caused by different weather conditions in these two locations. At the same time, you can reliably monitor energy efficiency improvements over time by extracting volatile weather influences. Weather normalization considers the nearest weather station available for a specific building and normalizes the energy consumption of the selected time period compared to the reference year 2020 with the so-called balance point method.

Activating Weather Normalization

To activate weather normalization, select the options menu > Data > Weather-adjusted. To deactivate the feature, select Data > Measured values.

Description

When the feature is activated, the widget displays data as follows:

  1. Weather-adjusted label: Indicates that weather normalization is enabled. Select the information button to see the list of currently supported weather stations.
  2. Measured total consumption value: The actual total consumption value is calculated by adding up the actual consumption values for the individual consumption groups.
  3. Actual and weather-adjusted total consumption: This bar chart displays the actual (dark blue bar) and the weather-adjusted (light blue bar) total consumption. To see the exact consumption values, place your mouse pointer on the blue bars.
  4. Adjusted total consumption value: The adjusted total consumption value is calculated by adding up the weather adjusted values for heating and cooling, while for the other consumption groups the actual values are considered.
  5. Weather-adjusted and actual value difference: The result of applying reference weather conditions is expressed as a percentage difference between the actual and the weather-adjusted value.
  6. Weather-adjusted value curve: The blue curve displayed in the chart represents the weather-adjusted total value calculated by adding up the weather adjusted values for heating and cooling, while for the other consumption groups the actual values are considered. To see the specific value, place your mouse pointer on the curve.
