Visualization(s)

Heating Signature

This visualization allows a quick detection of malfunctions and provides valuable information on the energy efficiency of the building.

• A constant indoor temperature is assumed.
• It is also assumed that the outside temperature is the parameter with the greatest influence on heating energy consumption.
• This method is suitable for buildings with stable internal heat loads and relatively low passive solar heat loads.

• The x-axis represents the average outdoor temperature.
• The y-axis the daily energy consumption.
• Tooltip: Place the mouse pointer over a datapoint to get more information of a specific measurement.
  
  

Settings

Basic

Energy Heat Meter Central

• Selection of the heat meter.

Temperature Outside Air

• Selection of the outside air temperature sensor.

Time Range

• The date left is automatically the oldest timestamp and on the right side the newest.
• Narrow the time range to make comparisons.

Visible Seasons

• The points are colored according to the season.
• With the checkboxes the measurements of a season can be shown and hidden individually.

Extended

• To access the extended settings, the plus symbol in the upper right corner of the title bar must be pressed.
• Per default the extended settings tab is collapsed.
  
  
  
  

Threshold to exclude low values for regression line

• Used for the regression line for outlier removal.
