Rulemaking Overview & Framework 4 1 Introduction

3 ScopeBuilding Technologies Program eere.energy.gov 8 

### • The Energy Policy and Conservation Act (EPCA) of 1975 (Public Law 94

- 163) established the energy conservation program

.



### • The amendments to EPCA in the National Appliance Energy Conservation Act of 1987 (Public Law 100

- 12) established energy conservation 

### standards for residential refrigeration products and required that DOE conduct two cycles of rulemakings to determine if more stringent 

### standards are justified 42 U.S.C. 6295(b).

– DOE fulfilled this obligation by publishing standards rules in 1989 and 1997.



### • The Energy Independence and Security Act (EISA) of 2007 (Public Law 

### 110

- 140) required that DOE publish a final rule determining whether to amend the standards in effect for residential refrigeration products 

### manufactured starting in 2014.

– DOE fulfilled this obligation by publishing new standards on September 15, 

### 2011. 76 FR 57516. 

## Regulatory History

Energy Conservation Standard for Refrigeration ProductsBuilding Technologies Program eere.energy.gov 9 

## Regulatory History

Current DOE standards do not address wine chillers and related



## refrigeration products.

• In 2001 DOE limited the application of its refrigerator standards to exclude wine chillers and similar products, because the refrigerator test procedure and standards were unable to account for specific wine chiller design and use requirements.



## • DOE opted to address wine chillers and other refrigeration products separately from refrigerators.



## • This action may lead to new and tailored standards for these products.

• DOE’s current definition for Electric Refrigerator (see 10 CFR 

## 430.2) excludes wine chillers due to storage temperature limits: “. . . designed to be capable of achieving storage temperatures above 32 ° F (0



### ° C) and below 39 ° F (3.9 ° C), . . .”Building Technologies Program eere.energy.gov 10 

## Regulatory History

Refrigerator Scope of Coverage



## • EPCA provides some scope

- related criteria, but specifies no temperature limits: 

## “. . . excluding those consumer products designed solely for use in recreational vehicles and other mobile equipment . . .” 42 U.S.C. 6292(a)



## “ Refrigerators, refrigerator

- freezers, and freezers which can be operated by alternating current electricity, excluding

-- 

### (A) any type designed to be used without doors; and (B) any type which does not include a compressor and condenser unit 

### as an integral part of the cabinet assembly.” 42 U.S.C. 6292(a)(1)



## • DOE has the authority to modify its current refrigerator definition (see 10 CFR 430.2) to include wine chiller and similar 

## products.

• This specific authority, however, does not cover products using 

## thermoelectric or absorption refrigeration.Building Technologies Program eere.energy.gov 11 

## Regulatory History

Refrigerator Scope of Coverage

• Establishing coverage over new consumer products requires:

– Minimum annual per household energy use of 100 kWh (42 U.S.C. 6292(b)(1)(B ))



### • To set an energy efficiency standard for a newly covered product, two key criteria must be met:

– Minimum average annual per household energy use associated with the product of 150 kWh, and

– National annual energy use of 4.2 billion kWh. (42 U.S.C. 6295(l)(1)(A, B))



### • If national energy use does not exceed 4.2 billion kWh, DOE would be 

### authorized to establish coverage but not efficiency standards.

– Coverage alone without setting a national standard would preempt State 

### standards that are already in place



### • DOE recently proposed covering AC

- powered thermoelectric and 

### absorption refrigeration products. See 76 FR 69147 (Nov. 8, 2011).Building Technologies Program eere.energy.gov 12 

## Regulatory History

• California has had its current wine chiller standards in effect for at 

## least a decade; Canada harmonized with the CA standards in 2008. 1



## • The regulations set standards for two product classes: automatic

defrost wine chillers and manual

- defrost wine chillers.



## • The California wine chiller standards do not make a distinction regarding the cooling technology used in the product.

• DOE has not been able to identify any thermoelectric units in the 

## CEC refrigerator database, implying either that these units do not meet the standards or that manufacturers are not aware that they 

## are covered. Existing State and Foreign Standards

1 The current set of Appliance Regulations (2010 Appliance Efficiency Regulations, California Code of Regulations, Title 20, Sections 1601 through 1608) became effective January 1, 2011. They were adopted by the California Energy Commission on November 18, 2009.

Rulemaking Overview & Framework 4 1 Introduction

3 ScopeBuilding Technologies Program eere.energy.gov 14 

## Scope

Summary of Coverage Options

• The coverage options DOE considered include:

1. Establish coverage and standards for vapor compression wine chillers by 

### modifying the refrigerator and refrigerator

- freezer definitions to include these products, and either: a) Establish coverage for thermoelectric and absorption products; or b) Do not pursue coverage for thermoelectric and absorption units.
2. Establish a new category of covered products for wine chillers and related products irrespective of the cooling technologies they use. This approach may preclude pursuit of energy standards for these products because of the 4.2 billion kWh statutory threshold.



## • DOE is tentatively considering Option 1(a).

Item 1

- 3 DOE requests comment on whether other coverage/standards options in addition to the ones described above are possible. DOE also seeks feedback regarding the merits of pursuing an approach based on Option 1(a).Building Technologies Program eere.energy.gov 15 

## Scope

Item 1

- 1 DOE requests shipment information from stakeholders for wine chillers and related refrigeration products. Segregation of such 

### data is desired if possible by type of refrigeration technology (thermoelectric, vapor

- compression, absorption), product size, 

### product class, and any other relevant characteristics.

Item 1

- 2 DOE requests energy use data for wine chillers and related refrigeration products. DOE requests that the data identify model 

### numbers or basic product information (e.g. cabinet volume) and that the method of determining the energy use be identified for such data

– i.e. identify the test procedure used and/or indicate that the data are estimates, field measurements, or results determined by other methods. DOE requests that such data be segregated if possible according to refrigeration technology, product class, and/or product size. 

## Request for CommentBuilding Technologies Program eere.energy.gov 16 • Absorption cooling

– a refrigeration technology that uses a heat source to provide the energy needed to drive the cooling system. These systems do not use a compressor.

• Thermoelectric cooling

– a refrigeration technology using a solid state heat pump to provide cooling via the Peltier effect. These systems do not use a compressor and condenser.

• Vapor compression cooling

– a refrigeration technology that uses a compressor and condenser to provide cooling.

• Automatic defrost

– a system in which the defrost cycle is automatically initiated and terminated, with resumption of normal refrigeration at the conclusion of the defrost operation. The system automatically prevents the permanent formation of frost on all refrigerated surfaces. Nominal refrigerated food temperatures are maintained during operation of the automatic defrost system(s). The defrost water is disposed of automatically.

• Manual defrost

– a method of removing frost and/or ice from the refrigerated surfaces accomplished by natural or manual means with manual initiation and manual termination of the overall defrost operation.

• Off

- cycle defrost

– a type of automatic defrost in which the re

- circulating air, which is warmer than 32  ̊F, melts ice build up on the evaporator when the compressor is off. 

## Scope

DefinitionsBuilding Technologies Program eere.energy.gov 17 

## Scope

• DOE is considering adopting the following definition for electric wine chiller :

– [A] cabinet designed for the refrigerated storage of beverages, non

perishable food products, and/or any other items, is not designed to be capable of achieving storage temperatures below 39 ° F (3.9 ° C), and having a source of refrigeration requiring single phase, alternating current electric 

### energy input.



## • The definition for refrigerator would be modified to include both 

## electric refrigerator and electric wine chiller

.

• Because some warmer

- storage products are not designed uniquely for wine, DOE is considering the possibility of applying a term 

## other than electric wine chiller to all products with storage temperatures warmer than 39  ̊F.

Wine Chiller DefinitionBuilding Technologies Program eere.energy.gov 18 

## Scope

• The majority of residential wine chiller sales are of products that fit the size criteria for compact refrigerators/refrigerator



## freezers/freezers.

• If DOE modifies the definition for refrigerator to include wine chillers, DOE may modify the definition of compact 

## refrigerator/refrigerator

- freezer/freezer as follows to avoid establishing a separate compact category of wine chiller:

– Compact refrigerator/refrigerator

- freezer/freezer means any refrigerator, refrigerator

- freezer or freezer with total volume less than 7.75 cubic feet 

### (220 liters) and 36 inches (0.91 meters) or less in height that is not an electric wine chiller. 

## Modification of Compact Products DefinitionsBuilding Technologies Program eere.energy.gov 19 

## Scope

Item 1

- 4 DOE requests comment on the suggested definition for wine chiller and the modified definitions for refrigerator and compact products described above.

Item 1

- 5 DOE requests comments from stakeholders regarding the selection of a term identifying the product category associated with 

### wine chillers and related refrigeration products whose compartment temperatures are warmer than 39  ̊F. In addition, DOE seeks 

### comment on whether multiple product categories are necessary to address such products.



## Request for CommentBuilding Technologies Program eere.energy.gov 20 

## Scope

• During the refrigerator rulemakings, DOE became aware of products that combine wine storage compartments with 

## refrigerator compartments and/or freezer compartments. 75 FR 78810, 78816

- 78817 (December 16, 2010).



## • DOE addressed these products in February 2011. 2



### – For refrigerators and refrigerator

- freezers, the addition of a “wine storage” compartment does not change its status and does not affect its coverage.

– The addition of a wine storage compartment to a freezer changes that product’s status and removes it from current coverage under DOE’s 

### regulations.

– DOE indicated that it was considering a rulemaking that would resolve some 

### of these issues. 

## Hybrid Products

## Scope

1. Set a threshold size for a wine storage compartment at which a refrigerator, 

### refrigerator

- freezer, or freezer is no longer one of these products and is instead classified as a “hybrid” product.


### 2. Establish definitions for hybrid products.
3. Develop test procedures for products for which the wine storage 

### compartments are smaller than the thresholds.
4. Apply the existing energy standards to these products that will still be 

### refrigerators, refrigerator

- freezers, or freezers under the modified definitions

. 5. Develop test procedures and energy standards for hybrid products falling out 

### of the modified definitions for refrigerator, refrigerator

- freezer, and/or freezer. 

## Potential Framework for Addressing Hybrid Products

Item 1

- 6 DOE requests general comments on its draft framework for 

### addressing products that include fresh food and/or freezer compartments as well as wine storage compartments.Building Technologies Program eere.energy.gov 22 

## Scope

Item 1

- 7 DOE seeks information regarding the types and configurations of products that might need to be considered under such a framework, including examples showing product details and 

### information on annual shipments associated with such products.

Item 1

- 8 DOE seeks comment on whether there should be a threshold size or percentage of total volume for wine storage compartments that would push a product out of the current definitions for refrigerator, refrigerator

- freezer, or freezer into hybrid product categories. If so, what should this threshold be? What types of hybrid product categories should be established?



### Item 1

- 9 DOE seeks comment on what kinds of test procedure revisions would be required to address these products, whether 

### covered under the existing product categories or by new categories?



## Request for CommentBuilding Technologies Program eere.energy.gov 23 

## Scope

Item 1

- 10 DOE seeks comment on whether DOE should include the 

### development of definitions, test procedures, and energy standards for hybrid products as part of a potential rulemaking. Item 1

- 19 DOE seeks comments from stakeholders regarding how compartments used in wine chillers and related refrigeration products that are currently not covered under the existing 

### refrigeration product definitions could be defined. What compartment types should be defined and what should their 

### standardized temperatures for energy testing be?



## Request for CommentBuilding Technologies Program eere.energy.gov 24 

## Other Residential Refrigeration Products 

## Scope

Item 1

- 13 DOE requests information regarding whether there are any residential refrigeration products not yet covered by energy 

### conservation standards, other than the wine chillers and related hybrid products, that DOE should regulate through energy 

### conservation standards. Assuming such products exist, what are they (i.e. types), what are their annual shipment levels in the U.S., and 

### what are their energy use characteristics? • DOE is considering, consistent with EPCA, extending coverage and establishing energy conservation standards for all other residential 

### refrigeration products that are currently unregulated.Building Technologies Program eere.energy.gov 25 

## Other Residential Refrigeration Products (cont.) 

## Scope

Item 1

- 14 DOE seeks information regarding residential ice makers, particularly: the annual sales levels for such products in the U.S.; whether test procedures addressing energy use for such products exists; the typical annual energy use of such a product in residential 

### settings; and other information DOE should consider in determining whether to regulate such products?

Item 1

- 17 DOE seeks information regarding the prevalence of “near

freezer” 3 

### products. DOE also seeks input regarding the need to revise the current definition of the freezer and/or the freezer test procedures to address such products. Further, DOE seeks input on 

### whether these products should fall under existing product classes or separate new product classes and energy standards. If the latter, 

### DOE requests comments regarding the nature of these revisions.

3 Near

- Freezers are discussed in more detail in the framework document. These are products that achieve freezing temperatures (below 32  ̊F), but do not maintain 0  ̊F temperature, as required by the DOE “freezer” definition.Building Technologies Program eere.energy.gov 26 

## Coverage of Wine Chillers in Residential and Commercial Applications 

## Scope

Item 1

- 15 DOE seeks comment on what design and performance characteristics distinguish wine chillers used in commercial applications from residential wine 

### chillers. DOE also requests comment on whether any wine chillers used in commercial applications are manufactured on the same product lines as 

### residential wine chillers. Finally, DOE seeks information as to whether any commercial wine chillers are distributed in commerce for personal or consumer 

### use. If so, DOE seeks details regarding the magnitude of those sales as a percentage of total sales of commercial products.



### Item 1

- 16 DOE seeks comment on whether commercial and residential wine chillers should be covered under the same test procedures and energy standards. • DOE is aware of several attributes that could distinguish commercial types 

### of wine chillers from residential types, but does not have sufficient information to definitively conclude that wine chillers with uniquely 

### commercial features exist.Building Technologies Program eere.energy.gov 27 

## Products that can Operate on both AC and DC electric power 

## Scope

Item 1

- 11 DOE seeks information regarding whether refrigeration products which operate on either alternating current (AC) or direct current (DC) 

### electricity are distributed to any significant extent in commerce for personal or consumer use in stationary applications (e.g., in homes). What types of such 

### products are sold, what are their annual shipment levels in the U.S., and what are their energy use characteristics?



### Item 1

- 12 DOE seeks comment on whether it should specifically extend coverage and develop test procedures, definitions, and energy standards for 

### refrigeration products that operate on either alternating current (AC) or direct current (DC) electricity. 

### • DOE is aware of products that can operate on either AC or DC power.

• Many of these products are marketed for mobile applications, and for that 

### reason would not be subject to EPCA coverage under 42 U.S.C . 6292.

• However, significant numbers of such products may be used in stationary 

### applications.Building Technologies Program eere.energy.gov 28 Preliminary Analysis & Test Procedure

## Preliminary Analysis & Test Procedure
Test Procedure



## • The Code of Federal Regulations (CFR) prescribes the DOE test procedures for residential refrigeration products.

– These test procedures do not include provisions for testing products that do not meet the current definition for electric refrigerators. In particular, 

### the standardized compartment temperatures specified in the test procedures are significantly lower than those typical for wine chillers.



## • The Association of Home Appliance Manufacturers (AHAM), the 

## California Energy Commission (CEC), and Natural Resources Canada ( NRCan ) all use a standardized compartment temperature 

## of 55  ̊F (12.8  ̊C). Past Test ProceduresBuilding Technologies Program eere.energy.gov 35 

### • The AHAM, CEC, and CSA test procedures for wine chillers apply a correction factor to the wine chiller energy use calculation to account for 

### average product usage.

• This factor reduces the measured energy use by 15% to determine daily 

### energy consumption for a given temperature setting in order to account for the expectation that such products would have fewer door openings, on 

### average, than a household refrigerator, may not be energized at all times, and/or other reasons that would reduce energy use. 

## Preliminary Analysis & Test Procedure
Test Procedure

Item 1

- 20 DOE requests comments on whether a correction factor is appropriate for calculating wine chiller energy use, and whether 0.85 

### is an appropriate value for the correction factor. DOE further requests information supporting the selection of any recommended 

### correction factor. 

## Correction FactorBuilding Technologies Program eere.energy.gov 36 

### • EPCA requires DOE to consider standby mode and off mode energy consumption when amending both its test procedures and energy 

### conservation standards.

• DOE expects that any modified version of the existing test procedures for 

### refrigeration products that DOE would develop for these products would capture standby and off mode energy use because the test procedure 

### measures all product energy use, including compressor “off” periods.

• DOE concludes that establishing special test procedures to address standby 

### and off modes is not required. 

## Preliminary Analysis & Test Procedure
Test Procedure

Item 1

- 21 DOE requests input from stakeholders on the its tentative conclusion that separate test procedures to address standby and off 

### modes are not required for wine chillers and related refrigeration products. 

## Standby and Off ModesBuilding Technologies Program eere.energy.gov 37 

## Test Procedure Key Issues 

## Preliminary Analysis & Test Procedure
Test Procedure

Item 1

- 18 DOE seeks comment regarding whether there are any other key 

### issues associated with development of test procedures for wine chillers and related refrigeration products, and, if so, what these issues are. • Establishing definitions for product categories and/or compartment types to 

### clarify which products are subject to which test requirements.

• Establishing standardized compartment temperatures that are appropriate 

### for the product categories.

• Testing of hybrid products.



### • Potential consideration of test procedures for commercial wine chillers.

• Applying a correction factor to determine the energy use of wine chillers and related products.

• Potential consideration of additional test procedure requirements to address standby and/or off mode energy use.Building Technologies Program eere.energy.gov 38

## Preliminary Analysis & Test Procedure Markups for Equipment Price Determination



## Types of Markups in Distribution Chain

• Baseline Markups:

– Markups relate consumer price to the cost of goods sold (CGS).

– Baseline markups relate price to cost prior to a change in efficiency.

– Baseline markups indicate a consumer price that covers all of a distributor’s or contractor’s expenses plus profit.



### • Incremental Markups:

– Incremental markups relate the incremental change in consumer price to the incremental change in CGS.

– Certain costs, such as direct labor costs (salaries, payroll, rental and occupancy), do not vary with efficiency induced changes in CGS and remain constant in the calculation of incremental markups.

– Incremental markups cover only expenses that vary with CGS in this case, expenses that increase due to an increase in equipment efficiency.Building Technologies Program eere.energy.gov 61

## Preliminary Analysis & Test Procedure Energy Use Characterization

• Typically, DOE relies on the Residential Energy Consumption Survey (RECS) to 

### estimate an appliance’s annual energy consumption. However, RECS has not attempted to obtain information on wine chillers.



### • Instead, California’s maximum energy use standards can be combined with sales data from the NPD Group to estimate a range of annual energy use values 

### for vapor

- compression wine chillers. Two limitations of this approach are:
1. only the maximum possible energy use of each model in the NPD 

### database can be defined, as opposed to its actual rated energy use, and
2. it is unknown as to whether the CEC test procedure provides a 

### reasonable estimate of wine chiller annual energy use.

• Because of the apparent lack of energy use data, DOE may rely on in situ field 

### measurements as a means to characterize wine chiller energy use.

Life

- Cycle Cost and Payback Period Analysis

• DOE analyzes the consumer impact of any new standards by dividing consumers into subgroups and accounting for variations in key inputs to the LCC analysis.



### • A consumer subgroup comprises a subset of the population that is likely, for one reason or another, to be affected disproportionately by new or revised 

### energy conservation standards.

– In comparing potential impacts on the different consumer subgroups, DOE 

### will evaluate variations in regional electricity prices, variations in energy use profiles, and variations in purchase prices that might affect the LCC of 

### an energy conservation standard to certain consumer subgroups.

- Cycle Cost and Payback Period Analysis

• DOE bases repair costs on annualized costs of key components and frequency of replacement in the field.



### • Typically, small incremental changes in product efficiency incur little or no changes in repair and maintenance costs over baseline products. There is a 

### greater probability that equipment with efficiencies that are significantly higher than the baseline will incur increased repair and maintenance costs, since such equipment is more likely to incorporate technologies that are not widely available.



### • Unless the efficiency increases considered for this rulemaking result in significantly larger or heavier products, DOE expects that more

- efficient wine 

### chillers and miscellaneous refrigeration equipment will not incur increased installation costs.
