The Consumption flow subpage enables tracking how consumption is distributed throughout specific location types (e.g., campus > buildings > floors > rooms & floor areas > room segments). Sankey diagrams visualize the energy flows for all consumption groups through the different location types within the selected site (campus or building). The meters that measure consumption of entire sites are called main meters. The meters that measure the lower sections such as floors and rooms are called submeters. Apart from the global filters for specifying the data visible in the diagram, this feature also comes with location type filter you can use to focus on specific parts of the site.

In case the diagram does not display data, make sure that:
You have configured at least one meter and a submeter.
The meters contain values.
The filters you applied do not prevent the required data from being displayed.

Description

  1. Data filters: These are standard filters used in Dashboard and Site details. For more information, see Filtering data.
  2. Locations filter: See Filtering locations below for more information.
  3. Consumption groups: Use this multiple selection dropdown list to choose which consumption groups to display in the Sankey diagram. Use the checkboxes to select the desired consumption groups. You can also use the search field to narrow down the list or select/deselect All consumption groups using the respective button. To save the options choose Apply filter. To close the list without saving, choose Clear filter.
  4. Remove filter: Remove all filters. This option is visible only when at least one filter is applied.
  5. Search: Use this field to filter the locations displayed on the Sankey diagram by their name. The search function supports searching for partial names.
  6. More: For more information, see Working with the diagram below.
  7. Submeter filter: For more information, see Filtering locations below.
  8. Sankey diagram: This diagram shows the consumption flow based on the filters you applied. The thickness of the line between individual nodes corresponds to the value it represents. To see the exact values, place your mouse pointer on the diagram.
  9. Consumption groups: Displays the legend for consumption groups. Select one to exclude/include it in the diagram. Select Total to sums up compatible consumption groups for each location shown - energy consumption groups at the top of the diagram, volume consumption groups at the bottom. Extra grey highlighted nodes are added to indicate what was summed up.

Filtering locations

There are two location filters available in the Consumption flow subpage.

Locations filter

This filter contains a hierarchical tree with all parts of the selected site. Expand or collapse individual options and use the checkboxes to include or exclude individual parts of the site in the Sankey diagram. You can use the search field for a quicker navigation. To save the options choose Apply filter. To close the list without saving, choose Clear filter.

Submeter filter

Select the buttons to include or exclude individual site parts (i.e., submeters) from the flow. It is necessary to keep the sequence of the location types continuous, i.e., it is not possible to unselect options that are in the middle of the flow.

Working with the diagram

Apart from the standard options, the consumption flow More button contains various visualization modes and consumption group summation:

  • Sort by location: Sorts Sankey diagram flowlines according to the physical structure of the buildings. See image below.
  • Minimize intersects: Straightens out Sankey diagram flowlines for better readability.
  • See comparison of the two views applied on the same set of data below.
  • Details: This view can be accessed from the View dropdown list or by double-clicking specific nodes (i.e. submeters) directly from the chart. See below for more details.

Details

The Details card allows you to deep-dive into a building's consumption and to compare individual nodes over time for consumption, costs, or CO2 emissions data. For the selected period of time, you can select and analyze up to 9 selected nodes. You can switch between two views - a stacked bar chart (default) and a line chart. Double-click a node in the Sankey diagram to open the submeter in Details. To add more submeters to the selection single click on the respective nodes. To deselect a submeter, click on the node again.

  1. Options: Use the View dropdown list to switch between the bar chart and line chart and select the required aggregation interval. Select Close to close the Details card.
  2. Chart: The horizontal axis represent the time; the vertical axis represents the consumption, costs, or CO2 emissions value. The colors correspond to the ones used in the sankey diagram.
  3. Details: Place your cursor in the chart to see the exact values for the selected point in time.
  4. Legend: Select individual options to include/exclude them from the chart.
