EPC

Used as

• Card

Summary

Display an EPC graph (EER or EIR) for a selection of histories over a given period. It takes into consideration whether it's gas, elec or fuel consumption.

Implementation

• Add a card from the settings bar, and choose in the list EPC
• Choose a selection of histories (Histories field)
• Choose a period (Period field) 
• Fill the tags fields to distinguish between the different sources of histories (electricity, gas and fuel).
  
• You can make it slave of another card. See Master Slave behavior between cards to have more information on how to use it with other cards

Flex Widget Properties

• Type: The type of graph to display: EER (Energy Efficiency Rating) or EIR (Environmental (C02) Impact Rating).
• HistoryDefaultSelection: A list of queries retrieved from the Selection folder in the BtibService. The selected query needs to point histories (history:).
• TimeRangeDefaultSelection: The time range to apply to the retrieved histories.
• TimeRangeSelectionPolicy: 
  • Stand Alone: The widget takes the time range from the properties
  • Slave: The time range is given by another widget like a period selector.
• Delta: whether to compute the relative difference between each value
  • Auto: Will compute the difference according to the tag "delta" present on the history. Apply false if the tag doesn't exist.
  • True: Will always compute the difference
  • False: Will never compute the difference
• Area: The surface area used to compute the ratio. You can use SFormat to retrieve the area in a slot in the station.
• Elec Tag: The tag associated with electricity histories.
• Gas Tag: The tag associated with gas histories.
• Fuel Tag: The tag associated with fuel histories.
• Elec Coef: Coefficient to apply on electricity consumption (default 2.58).
• CO2ElecCoef: (EIR graph) Coefficient to apply on electricity consumption percentage ratio (default 0.023). 
• CO2GasCoef: (EIR graph) Coefficient to apply on gas consumption percentage ratio (default 0.055). 
• CO2FuelCoef: (EIR graph) Coefficient to apply on fuel consumption percentage ratio (default 0.074). 
• LegendTop: The legend to display on the top of the graph.
   SFormat is supported.
• LegendBottom: The legend to display on the bottom of the graph.
   SFormat is supported.
• ValueTitle: The title for the value column.
   SFormat is supported.
• ShowValueWithScaleName: Display the value with the scale name instead of a number. 
• ShowValueWithScaleColor: Display the value with colors associated with the scale.
