Energy Consumption Efficiency
[Homeuse freezers]
●Categories & Target Standard Values (1)
Energy consumption efficiency shall be annual energy consumption (kWh/year) measured by a method stipulated in JIS C 9801 (2006).
●Categories & Target Standard Values (2)
Energy consumption efficiency shall be annual energy consumption (kWh/year) measured by a method stipulated in JIS C 98013 (2015).
[Businessuse freezers ]
●Energy consumption efficiency shall be annual energy consumption (kWh/year) measured by a method stipulated in JIS B 8630 (2009).
Categories & Target Standard Values
In the target fiscal year and each subsequent fiscal year, for each category, the weighted average value obtained by weighting energy consumption efficiency with shipment volume shall not be above the target standard value which is a weighted average value obtained by weighting standard energy consumption efficiency^{*1} with shipment volume.
*1: Values obtained from the standard energy consumption efficiency calculation formulas and rounded to the nearest integers. 
[Homeuse freezers]
(1) Freezers whose target fiscal year is FY2010 and each subsequent fiscal year (until FY2020)
Category  Standard energy consumption efficiency calculation formula  

Category name  Cooling type  Rated internal volume  
A  Cold airnatural convection type  ―  E_{1} = 0.844V_{1} + 155 
B  Cold airforced circulation type  Up to 300 liters  E_{1} = 0.774V_{1} + 220 
C  Over 300 liters  E_{1} = 0.302V_{1} + 343 
Remarks:  E_{1} and V_{1} express the following numerical values. 
E_{1}: Standard energy consumption efficiency (unit: kWh/year)  
V_{1}: Adjusted internal volume It shall be a value obtained first by multiplying the rated internal volume of a freezing compartment by either 2.20 for threestar type, 1.87 for twostar type, or 1.54 for onestar type, and then rounded to the nearest integer. (unit: liter) 
(2) Freezers whose target fiscal year is FY2021 and each subsequent fiscal year
Category  Standard energy consumption efficiency calculation formula  

Category name  Storage compartment  Cooling type  
a  Freezer  Cold airnatural convection type  E_{3} = 0.589V_{3} + 74 
b  Cold airforced circulation type  E_{3} = 1.328V_{3} + 80 
Remarks:  E_{3} and V_{3} express the following numerical values.  
E_{3}: Standard energy consumption efficiency (unit: kWh/year)  
V_{3}: Adjusted internal volume (unit: liter) It is a total sum of the values obtained by multiplying the rated internal volume of each storage compartment by the adjusted internal volume coefficient respectively, which shall be obtained from the following formula and rounded to the nearest integer. 

K_{ci}: Adjusted internal volume coefficient, which is a value given in the right column of the table below for each type of storage compartment given in the left column.  
V_{i}: Rated internal volume, which is a value for each type of storage compartment given in the left column of the table below. (unit: liter)  
n: Number of storage compartments in a freezer

(3) Freezers whose target fiscal year is FY2016 and each subsequent fiscal year
Category  Standard energy consumption efficiency calculation formula  

Category name  Shape  
3A  Vertical type  E_{2} = 1.96V_{2} + 186n_{F} + 295d_{F} + 788 
3B  Horizontal type  E_{2} = 4.12V_{2} + 157n_{F} + 157d_{F} + 349 
4A  Chest freezer  E_{2} = 1.16V_{2} + 211 
4B  Freezerstocker  E_{2} = 1.39V_{2} + 359
