Energy label

 

The energy performance certificate reflects the energy unit (kWh/m2*a) which differs from a natural energy unit, i.e. the unit measured by an energy metre by method. According to approved rules, heating costs of different years are reduced to heating costs reduced to a normal year based on degree days, and different energy components are then multiplied by conventional weighting factors. For example, in case of electricity, the actual energy consumption is multiplied by two for the energy performance certificate, and in case of district heating, heating costs reduced to a normal year are multiplied by coefficient 0.9 or by 0.65 in case of an efficient district heating.
