Daily Electric Energy Consumption and Standby Power

A simple overview of the time series data per room.


  • The chart is splitted in two subplots:
    • upper plot with daily energy consumption in kWh/day
    • lower plot with standby-losses in Watts
  • The points represent a rolling mean value of the last seven days
  • The solid dashed lines represent the total mean value of the visible points. On the right are two text annotations with the values of these two lines.
  • A horizontal line with a left aligned annotation shows a typical houshold for comparison. Calculated with extended settings (described below). Formulas and values from [1]
  • Tooltip: Place the mouse pointer over a datapoint to get more information of a specific measurement.

Settings

Basic



Flat and Room

  • Selection of flat resp. room which should get analyzed.
  • According to the building hierarchy all flats and rooms get listet which have a datapoint of type “tempRoom” or “humRoom”.

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.
  • All the settings below are used to calculate the “typical household” consumption.
  • Please note that you only have to select devices that are really connected to the corresponding electric meter.



  • Depending on the setting and Settings > App Configuration > Building Type the typical consumption changes.
  • For detailed values, bachground information and formulas see [1]
  • Adaptions of the extended settings does not (yet) get changed.

Occupants

  • Default value comes from Settings > Building Hierarchy > occupants
  • The persons should be present at least on working days, i.e. at least in the evening and usually for 2 meals.
  • Children up to approx. 10 years are to be counted as approx. “½ person”.
  • Teenagers from about 11 years on are to be counted as adults.

Rooms

  • If the effective room number deviates significantly, i.e. by more than 1, from a “typical room number”, the typical energy consumption is adjusted accordingly.

Dishwasher

  • none: no dishwasher powered with this meter
  • classic: dishwasher available, no further classification
  • with hot water supply: electrical dishwasher which uses as well hot water to heat up

Freezer

  • none: no “big” freezer powered with this meter. The one in the refrigerator does not count.
  • classic: additional freezer available, no further classification

Cooking & Baking

  • If cooking and baking is particularly intensive and often, and little hot food is eaten outdoors, this increases the base value by 50 per person.
  • Conversely, if the stove and oven are used less intensively and food is eaten outdoors frequently, this reduces the base value by 50 per person.

Efficient Lighting

  • The mix values apply to a share of efficient lamps of about 40 to 50% (energy saving lamps, LED, fluorescent tubes).
  • Attention: Halogen or “Eco-Halogen” lamps are not efficient!
  • Majority means more than 80%, minority less than 20%

Clothes Dryer

  • none: no dryer powered with this meter
  • room air dryer: room air dehumidifier in the drying room
  • heat pumpt dryer: dryer with integrated heat pump, uses less energy than classic one!
  • classic dryer: classical one which is only connected to the electric power

Washing Machine

  • none: no washing machine powered with this meter
  • classic: washing machine available, no further classification
  • with hot water supply: electrical washing machine which uses as well hot water to heat up

Water Heater

  • none: no water heater powered with this meter
  • Electric Boiler: separate electric boiler powered with this meter
  • Heat Pump: only for single family houses when the water heater is connected to the meter

Common electricity (building equipment, common lighting)

  • included: e.g. for single family houses with main meter
  • excluded: e.g. for multi family houses where the meter of the flat gets analyzed. Normally the common electricity is measured by a separate meter.
