ANNEX B – Calculation of the energy efficiency index (EEI)   
 
 
B.1 General Principles   
For the calculation of the Energy Efficiency Index (EEI), of refrigerating appliance model, the Annual 
Energy Consumption of refrigerating appliance is compared to its Standard Annual Energy 
Consumption.  
 
The Energy Efficiency Index (EEI) is calculated and rounded to the first decimal place, as:  
 
𝐸𝐸𝐼 = 100  𝑥𝐴𝐸𝑐
𝑆𝐸𝐴𝑐                                       Eq. (B1) 
Where:  
 
AEC = Annual Energy Consumption of the refrigerating appliance   
SAE C = Standard Annual Energy Consumption of the refrigerating appliance.   
B.2 Determination of the Annual Energy Consumption AE C  
The Annual Energy Consumption (AEC) is calculated in kWh/year and rounded to two decimal places, 
as: 
 
The Energy Efficiency Index (EEI) is calculated and rounded to the first decimal place, as:  
 
𝐴𝐸𝑐 = 365  𝑥 𝐸24ℎ Eq. (B2)  
 
Where  
 
E24h is the energy consumption of the refrigerating appliance in kWh/24h and  rounded to three 
decimal places.   
B.3 Determination of the Standard Annual Energy Consumption (SAE C)  
The Standard Annual Energy Consumption (SAE C) is calculated in kWh/year and rounded to two 
decimal places, as:  
 
The Energy Efficiency Index (EEI) is calculated and rounded to the first decimal place, as:  
 
SAE c = V eq x M + N + CH           Eq. (B3)  
 
Where:  
 
• Veq is the equivalent volume of the refrigerating appliance   
• CH is equal to 50 kWh/year for refrigerating appliances with a chill compartment with a storage 
volume of at least 15 litres; otherwise, CH is equal to 0 kWh/year.   
• The M and N values are given in Table B3 for each refrigerating appliance category.

B.4 Calculation of the Volume equivalent used for the calculation of the Standard Annual 
Energy Consumption SAE C 
The equivalent volume of a refrigerating appliance is the sum of the equivalent volumes of all 
compartments. It is calculated in liters and rounded to the nearest integer as:   
 
 
𝑉𝑒𝑞= [∑ 𝑉𝑐𝑐=𝑛
𝑐=1 𝑥(25−𝑇𝑐)
20𝑥𝐹𝐹𝑐 ]𝑥 𝐶𝐶 𝑥 𝐵𝐼                                                                                                                   Eq. (B4)  
 
Where:  
 
• n is the number of compartments   
• Vc is the storage volume of the compartment(s)  
• Tc is the nominal temperature of the compartment(s) as set out in Table 3   
• is the thermodynamic factor as set in Table B1   
• FFc , CC and BI are volume correction factors as set out in Table B2  
 
The thermodynamic correction factor  (25−𝑇𝑐)
20 is the temperature difference between the nominal  
 
temperature of a compartment Tc (defined in Table 2) and the ambient temperature under sta ndard 
test conditions at + 25 °C, expressed as a ratio of the same difference for a fresh -food compartment at 
+ 5 °C.  
 
The thermodynamic factors for the compartments are set out in Table B1.

Notes:        
(i) for multi -use compartments, the thermodynamic factor is determined by the nominal temperature as given 
in Table 2 of the coldest compartment type capable of being set by the end-user and maintained continuously 
according to the manufacturer’s instructions;   
(ii) for any two -star section (within a freezer) the thermodynamic factor is determined at Tc = – 12 °C;   
(iii) for other compartments the thermodynamic factor is determined by the coldest design 
temperature capable of being set by the end -user and maintained continuously according to the 
manufacturer’s instructions.

Table B2 – Value of correction factors FF, CC and BI   
Correction factor  Value  Conditions  
   
FF (frost -free) 1.2 For frost -free frozen -food compartment  
1.0 Otherwise   
CC (climate class)  1.2 For T class (tropical) appliances  
1.1 For ST (subtropical) appliances  
 1.0 Otherwise  
BI (built -in) 1.2 For built -in appliances under 58cm in width  
1.0 Otherwise   
Notes:   
(i) FF is the volume correction factor for frost -free compartments.   
(ii) CC is the volume correction factor for a given climate class. If a refrigerating appliance is 
classified in more than one climate class, the climate class with the highest correction factor is 
used for the calculation of the equivalent volume.   
(iii) BI is the volume correction factor for built -in appliances  
 
 
B.5 Determination of the M and N coefficient used for calculation of the Standard Annual 
Energy Consumption SAE C 
 
The coefficient M and N are determined based upon the category of refrigerating appliance 
according with Table B3

1 0.233  245

5 0.450  245 
6 0.777  303 
7 0.777  303 
8 0.539  315 
9 0.472  286 
10 (*) (*)  
(*) for Category 10 refrigerating appliances the M and N values depend on the temperature and 
star rating of the compartment with the lowest storage temperature capable of being set by the 
end-user and maintained continuously according to the manufacturer’s instructions. When only 
an ‘other compartment’ as defined in Table 2 and Annex I, point (p), is p resent, the M and N 
values for Category 1 are used. Appliances with three -star compartments or food -freezer 
compartments are considered to be refrigerator -freezers
