Seasonal Efficiency: New Energy Efficiency Label

From January 2013, the energy performance calculation for air conditioning systems changed
from an overall EU based standard of EER and COP to a new standard based on seasonal
efficiencies of SEER and SCOP. These changes to the Energy Related Products Directive or ErP
are designed to give consumers a better understanding of the real efficiency of air conditioning
and heat pump systems whose nominal power rating does not exceed 12kW.
Undergoing gradual implementation from 1 January 2013 until 1 January 2019, the schedule
for each product category is as follows:
01 January 2013: A+++, A++, A+, A, B, C, D, E, F and G.
01 January 2015: A+++, A++, A+, A, B, C, D, E and F.
01 January 2017: A+++, A++, A+, A, B, C, D and E.
01 January 2019: A+++, A++, A+, A, B, C and D.

Seasonal Energy Efficiency Ratio (SEER) – This is the overall energy efficiency ratio of the
unit, representative of the entire cooling season. It is calculated as the annual cooling
demand divided by the annual consumption of electricity for cooling.
Seasonal Coefficient of Performance (SCOP) - This is the overall coefficient of performance
of the unit, representative of the entire heating season designated (the value of SCOP
corresponds to a determined heating season). It is calculated by dividing the reference
annual heating demand by the annual consumption of electricity for heating.
