COPON

COPON is a seasonal performance factor for the heat pump that includes electricity of the backup heater. COPON is calculated by the total electricity used by the heat pump and the backup heater over the total heat demand of the building. (LhpC_tp*COPC_tp+resC_tp)/LhsysC_tp  
SCOP is a seasonal performance factor which unlike COPON, also includes the electricity consumption of auxiliary energy for the heat pump operating in thermostat off mode, off mode and crankcase heater mode.  
The energy of the backup heater is included in all seasonal performance factors that results from the excel-calculation sheet.
The annual electricity consumption split up in supplementary heating, heat pump operation and auxiliary heating is given from the calculations.  
The annual carbon emission and label energy class is also result of the calculations
