　 b. ones having a closed top face and three of the side faces composed of translucent material,

　 c. ones having a height of over 1,650 mm or with a total motor rated power consumption of over 300 watts, whose refrigeration unit being installed at the upper part of its main body,

　 d. ones that do not generate air curtain, which refers to airflow for reducing effects of surrounding temperature, etc. on the inside of the showcase (the same applies to “e”.), or that generate air curtain and have the maximum external depth dimension of 800 mm or more, among those having a closed top face and at least one of the side faces open all the time,

　 e. ones generating air curtain on the top and either having the average inside temperature of 15°C, being the cold air-natural convection type or having two display compartments, which refer to compartments for displaying items stored inside while keeping them cold,

　 f. ones manufactured for an orderer in accordance with housing dimensions, air blower, refrigerating unit or heater capacity, insulation performance, or lighting performance specifications defined based on the orderer's instructions, annual shipment volume of which is less than 10 units.

Energy consumption efficiency shall be annual energy consumption (kWh/year) measured by a method stipulated in Appendix JA, JIS B 8631-2 (2011).

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.

Category							Standard energy consumption efficiency calculation formula
Category name	Type of shutting off ambient air	Shape	Temperature zone		Cooling type	Type of door
1A	Closed type	Box type	Refrigeration		Cold air-forced circulation type	Swing/Slide	E = 2.24V1 + 150
1B		Four-face/five-face glass type				Swing	E = 4.16V2 + 85
1C		Reach-in type (with a refrigeration unit installed at the bottom)					E = 2.61V3 － 217
1D						Slide	E = 0.822V3 + 694
1E			Freezing			Swing	E = 5.08V3 + 4274
1F		Glass top type			Cold air-natural convection type	Slide	E = 4.11V2 + 440
1G					Cold air-forced circulation type		E = 19.5V2 + 1643
2A	Open type	Multi-shelf type (ceiling air-blow type) (thin type)	Refrigeration	Medium temperature	Cold air-forced circulation type	―	E = 11.6V4 － 440

2F				Medium temperature			E = 20.7V2 + 1558

Remarks:

“Thin type” refers to a product type whose depth based on the maximum external dimensions stipulated in JIS B 8631-1 (2011) (hereinafter referred to as “product depth dimension”) (unit: mm) is less than 800 mm. “One-sided” refers to a product having only one display compartment stipulated in JIS B 8631-1 (2011). “Swing” refers to a type of door that has a rotation axis on one side and pivots around the axis to open or close. “Slide” refers to a type of the door that opens or closes by moving, along a rail, in parallel to the face where the door is installed. E: Standard energy consumption efficiency (unit: kWh/year) V1, V2, V3 or V4: Adjusted cooling internal volume (unit: liter) 　　　　　　　　 It shall be a value obtained from the formula given for each category in the right 　　　　　　　　 column of the table below and rounded to the nearest integer. D: Product depth dimension d: Depth dimension of the ceiling part (hereinafter referred to as “ceiling depth dimension”) (unit: mm) V: Cooling internal volume (unit: liter) as stipulated in Appendix JB, JIS B8631-2 (2011). Category name Adjusted cooling internal volume 1A V1 = (550 / D) × V 1B V2 = V 1C V3 = (800 / D) × V 1D V3 = (800 / D) × V 1E V3 = (800 / D) × V 1F V2 = V 1G V2 = V 2A V4 = (600 / ((d + D) / 2)) × V 2B V4 = (600 / ((d + D) / 2)) × V 2C V2 = V 2D V2 = V 2E V2 = V 2F V2 = V However, if the adjusted cooling internal volume obtained from the above formula is lower than the lower limit value given for each category in the right column of the table below, the lower limit value shall be used as the adjusted cooling internal volume. Category name Lower limit value of adjusted cooling internal volume 1A 172 1B 174 1C 444 1D 857 1E 389 1F 66 1G 374 2A 356 2B 267 2C 90 2D 178 2E 207 2F 163
