Energy labelling is part of a European Climate Change program, targeting energy efficiency as one method of reducing CO2 emissions. The European Commission determines that improved awareness will enable users to purchase the most ecologically economic unit for their needs. 

What?
The label provides information on air conditioning unit energy consumption. Units with cooling (and heating?) capacities up to 12kW are classified by energy consumption in categories from ‘A’ to ‘G’ and colour coded accordingly. The most energy efficient ‘A’ category units are indicated by a dark green arrow and the least efficient ‘G’ category units, by a red arrow. Thus users can compare the efficiencies of equal types of unit from different brands.

What is listed on the label:
Manufacturer’s name and logo and type of indoor and outdoor units (*).

1. Unit energy efficiency in cooling and heating modes:
   
   

   Cooling mode	Heating mode
   EER > 3.20	COP > 3.60
   EER  3.20 > 3.00	COP 3.60 > 3.40
   EER  3.00 > 2.80	COP 3.40 > 3.20
   EER  2.80 > 2.60	COP 3.20 > 2.80
   EER  2.60 > 2.40	COP 2.80 > 2.60
   EER  2.40 > 2.20	COP 2.60 > 2.40
   EER  2.20 >	COP 2.40 >

   
   
2. Noise level:  
   For indoor units only.
   
3. Indicated annual energy consumption:
   Approximate annual energy consumed is indicated, based on a standard residential model. 
   Annual consumption is calculated by multiplying total power input by an average of 500 hr/year IN COOLING MODE AT FULL LOAD. Annual energy consumption cost is calculated by multiplying this figure by user’s electricity tariff.
   
4. Cooling output:
   Is the unit’s cooling capacity in kW operating in cooling mode at full load. Users should select a unit with a rated output sufficient for their cooling/heating requirements. Oversized units can increase on/off cycling, shortening service life and undersized units will not provide adequate cooling or heating. Output figures can be obtained from the manufacturer or local dealer.
   
5. Energy efficiency ratio (EER):
   Is the unit’s cooling output divided by the total electrical power input required to deliver it – the higher the EER, the greater the energy efficiency.
   
6. Type:
   Indicates whether the unit is a cooling only or cooling/heating model.
   Cooling mode indicates whether the unit is water or air cooled.
   
7. Heating output:
   Is the heating capacity of the unit in kW, operating in heating mode at full load. 

* For multi models, Daikin indicates a single outdoor unit with a maximum of 2 wall mounted indoor units – for other units, refer to the ‘multi’ brochure.
