B.1 INTRODUCTION 

This appendix presents baseline specifications and detailed cost-efficiency results for 

each of the fifteen commercial refrigeration equipment (CRE) equipment classes analyzed in the 

engineering analysis (Chapter 5). 

B.2 BASELINE SPECIFICATIONS 

Table B.2.1 shows baseline design options for each of the fifteen commercial 

refrigeration equipment classes analyzed in the engineering analysis. All changes to cost and 

efficiency are measured relative to this level in the engineering analysis. Refer to Chapter 5 of 

the TSD for details about each baseline technology. 

Table B.2.2 shows baseline specifications (or case design specifications) for each of the 

CRE equipment classes analyzed in the engineering analysis. These specifications include 

dimensions, numbers of components, temperatures, nominal power ratings, and other case 

features that are necessary to calculate the energy consumption of each equipment class. In 

conjunction with baseline design option levels, the baseline specifications define the energy 

consumption and cost of the typical minimum technology equipment on the market.

B.3 CHANGES TO LED LIGHTING ASSUMPTIONS 

This section details changes to the LED lighting assumptions in the final rule engineering 

analysis relative to the Notice of Proposed Rulemaking (NOPR) by equipment class. Changes to 

the LED lighting assumptions for the 15 equipment classes analyzed in the NOPR are presented. 

If no mention is made of a particular value, that value remained unchanged from the NOPR. 

B.3.1 LED Lighting Prices 

For the NOPR, DOE could only identify LED luminaires on the market specifically for use 

in vertical refrigerated cases with transparent doors (i.e., the VCT equipment family). Since DOE 

could not identify LED luminaires specifically for use in open refrigerated cases (i.e., the VOP 

equipment family), DOE used the LED luminaires specifically for use in vertical refrigerated cases 

with transparent doors as the basis for the LED lighting for open refrigerated cases. When DOE reexamined the current state of LED lighting for the final rule, DOE was able to identify LED 

luminaires on the market specifically for use in open refrigerated cases. DOE updated the LED 

lighting prices for open refrigerated cases using these newly identified LED luminaires. DOE 

determined that the cost of a 4 foot, 15 Watt, 888 lumen output LED luminaire is $90.00. 

For the final rule, DOE also updated the LED prices for lighting used in the VCT 

equipment family using the actual reduction in the lumen-based price of LED chips reported in 

DOE’s Multi-Year Program Plan between 2007 and 2008. DOE’s 2007 Multi-Year Program Plan 

reported that the latest available OEM device price for LED chips was $35/kilolumen.1

 DOE’s 

2008 Multi-Year Program Plan reported that the latest available OEM device price for LED chips 

was $25/kilolumen.2 This equates to a 29 percent reduction in lumen-based LED chip costs from 

2007 to 2008. For the final rule, DOE applied this 29 percent reduction in lumen-based LED chip 

costs to the LED lighting for the VCT equipment families, representing about a 9 percent reduction 

in LED system cost, assuming the costs of the power supply and LED fixtures did not change from 

the values used in the NOPR engineering analysis. 

In the NOPR, because of the rapid development of LED technology, DOE conducted a 

sensitivity analysis to determine the economic impact of projected LED price reductions. As part 

of that sensitivity analysis, DOE broke down the cost of the LED system, by using the LED 

specifications in the NOPR engineering analysis and information obtained from LED lighting and 

integrated circuit manufacturers, to estimate the cost of the LED chips. For the final rule, DOE 

modified the cost breakdown from the NOPR (but maintained the total LED system cost) for the 

VCT equipment family. The 2007 total price of LED chips of the LED lighting system used in the 

VCT equipment family for the NOPR was $94.77. DOE applied the lumen-based price reductions 

reported in the DOE’s Multi-Year Program Plan from 2007 to 2008 to the $94.77 from the NOPR 

to arrive at the 2008 value of $82.74. Maintaining the power supply and LED fixture cost from the 

modified NOPR, the LED system cost breakdown results in a total LED system cost of $114.99 for 

the final rule. The estimated cost breakdown used to calculate a total LED system cost for the 

VCT equipment family is shown in Table B.3.1.

B.3.2 LED Lighting Configurations 

For the final rule, DOE was able to identify LED lighting specifically for use in both open 

refrigerated cases and refrigerated cases with transparent doors. Based on the new LED lighting 

identified for the final rule, DOE updated the case lighting configurations for each equipment class 

in the engineering analysis. 

Lighting for use in cases with transparent doors function differently than lighting for use in 

cases without doors. Cases with transparent doors typically display boxed merchandise and only 

products on the front of the shelves are visible to the consumer. Therefore, the only portion of the 

display case that requires illumination is the area on the front surface of the case at the front of the 

shelves. Since this is only a limited area that requires lighting, LEDs offer an advantage over 

fluorescent lighting in vertical refrigerated cases with transparent doors because of the directional 

nature of LED lighting. 

For the VCT equipment family, DOE assumed one fluorescent bulb on each mullion and a 

fluorescent bulb on each end of the case. There are two different types of LED lighting used in 

cases with transparent doors. A center mullion lighting fixture is used between doors and is 

designed to have half of the LED chips directed towards one door and half of the LED chips 

directed towards the other door. An end mullion lighting fixture has half the light output, cost, and 

power consumption of a center mullion lighting fixture. The LED chips in an end mullion lighting 

fixture are all directed towards the one door next to which they are located. Therefore, two end 

mullion lighting fixtures are the approximately equivalent to a single center mullion lighting 

fixture with regard to cost, light output, and power consumption. DOE modeled the LED lighting 

for the VCT equipment family using a center mullion lighting fixture and assumed one center 

mullion lighting fixture per door. Illustrative front views of the lighting configurations for both 

fluorescent and LED lighting for the VCT equipment family are shown in Figure B.3.1, Figure 

B.3.2, and Figure B.3.3. The red strips represent a fluorescent bulb inside the refrigerated volume, 

the blue strips represent an LED center mullion lighting fixture inside the refrigerated volume, and 

the green strips represent an LED end mullion lighting fixture inside the refrigerated volume.

Figure B.3.3 Lighting Configurations for VCT.SC.I 

For equipment classes without doors (i.e., VOP, SVO, SOC, and HZO equipment families), 

merchandise throughout the entire refrigerated volume is visible to the consumer. Therefore, the 

entire refrigerated volume must be illuminated.1 For this application, the directional nature of 

LED lighting tends to be less effective than fluorescent lighting, which outputs light in all 

directions surrounding the bulb. Based on discussions with LED refrigerated display case lighting 

manufacturers and comments from commercial refrigeration equipment manufacturers, DOE 

determined that there are two different types of LED luminaires used in open cases. An LED shelf 

light is used to illuminate merchandise close to it. Due to the directional nature of the light output 

from an LED luminaire, DOE assumes that two LED shelf lights are used per shelf to provide the 

desired illumination throughout an entire shelf: one on the front of the shelf and one midway under 

the shelf. An LED canopy light is typically located on the canopy of a display case. An LED 

canopy light has effectively twice the light output, cost, and power consumption of an LED shelf 

light and is typically used to provide additional illumination of the product in the bottom well of 

the display case. DOE modeled the LED lighting for the VOP, SVO, and SOC equipment families 

using an LED shelf light (i.e., DOE used two LED shelf lights as an approximation of one LED 

canopy light). DOE also assumed that the number of LED lighting fixtures per shelf would have 

to be doubled from what was assumed for fluorescent lighting in order to provide adequate 

illumination for the merchandise displayed on each shelf. Illustrative cross-sections of lighting 

configurations for both fluorescent and LED lighting for the VOP, SVO, and SOC equipment

 DOE assumes that the HZO equipment family does not contain any lighting because the ambient light of the store 

provides adequate illumination of the displayed merchandise.
