## APPENDIX B. ENGINEERING DATA

B.1 INTRODUCTION

This appendix presents baseline specificati ons and detailed cost-efficiency results for each of the fifteen commercial refrigeration equi pment (CRE) equipment classes analyzed in the engineering analys is (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. Al l 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 engineer ing analysis. These specifications include dimensions, numbers of components, temperat ures, 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 sp ecifications define the energy consumption and cost of the typical mi nimum technology equipment on the market.

## B.3 CHANGES TO LED LIGHTING ASSUMPTIONS

This section details changes to the LED lighti ng assumptions in the final rule engineering analysis relative to the Notice of Proposed Rule making (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 lu minaires 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 sp ecifically for use in vert ical refrigerated cases with transparent doors as the basis for the LED ligh ting 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 us ing 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 repo rted that the latest availabl e 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 po wer supply and LED fixtur es 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 imp act of projected LED pri ce 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 Pl an 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 differen tly than lighting for use in cases without doors. Cases with transparent doo rs typically display box ed merchandise and only products on the front of the shelves are visible to the consumer. Th erefore, the only portion of the display case that requires illumination is the area on th e 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 re frigerated cases with transparen t doors because of the directional nature of LED lighting.

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

fluorescent bulb on each end of the case. There ar e two different types of LED lighting used in cases with transparent doors. A center mullion lighting fixt ure is used between doors and is designed to have half of the LED chips direct ed towards one door and half of the LED chips directed towards the other door. An end mullion ligh ting fixture has half the light output, cost, and power consumption of a center mullion lighting fixt ure. The LED chips in an end mullion lighting

fixture are all directed towards the one door next to which they are located. Ther efore, two end mullion lighting fixtures are th e approximately equivalent to a single center mullion lighting fixture with regard to cost, lig ht output, and power consumpti on. 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 equipm ent 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 re frigerated volume, and the green strips represent an LED end mullion li ghting 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 re frigerated volume is visible to the consumer. Therefore, the entire refrigerated volume must be illuminated. 1 

## For this application, th e directional nature of LED lighting tends to be less effective than fluorescent lighting, which outputs light in all directions surrounding the bulb. Ba sed on discussions with LED refr igerated display case lighting

manufacturers and comments from commercial refrigeration equipment manufacturers, DOE determined that there are two different types of LE D luminaires used in open cases. An LED shelf light is used to illuminate mercha ndise close to it. Due to the dire ctional nature of the light output from an LED luminaire, DOE assu mes that two LED shelf lights are used per shelf to provide the desired illumination throughout an en tire shelf: one on the front of the shelf and one midway under the shelf. An LED canopy light is typically lo cated on the canopy of a display case. An LED canopy light has effectively twice the light output, cost, and powe r consumption of an LED shelf light and is typically used to provide additional illu mination of the product in the bottom well of the display case. DOE modeled the LED lighti ng 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 fluor escent 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
