See section 5A.5 at pp. 5A28 through 5A45 of the TSD for the June 2014 ECS final rule, Docket EERE2008BTSTD00150131.

Issue 33: DOE seeks comment on whether the representative minimum and maximum capacities listed in Table II.15 of this document are appropriate for walk-ins of 3,000 square feet or less.
Specifically, DOE is interested in whether the highest capacities listed for each equipment class in Table II.15 of this document appropriately represent walk-ins within the scope of DOEs energy conservation standards and/or sufficiently representative of models up to the largest capacities. If the highest capacities listed for each equipment class in Table II.15 of this document are not representative, DOE requests data and supporting information as to why they are not representative, and what appropriate maximum capacities for each equipment class would be.
Issue 34: DOE seeks comment on the appropriateness of the compressor types associated with each representative unit. Specifically, DOE seeks data on the respective ranges of refrigeration system capacities for which each compressor type scroll, hermetic, and semihermetic may realistically be used.
Further, DOE seeks comment on if there are refrigeration system capacity ranges for which multiple types of compressors may be used.
DOEs initial research into singlepackage refrigeration systems indicates that capacities range between 1,900 Btu/
h and 29,000 Btu/h, with most units less than 17,000 Btu/h. In order to conduct an engineering analysis for singlepackage refrigeration systems, DOE
seeks information on the capacities of the most representative units on the market.
Issue 35: DOE requests comment on appropriate representative capacities for single-package refrigeration systems.
Specifically, DOE requests data on the availability and prevalence of singlepackage units sized between 17,000 Btu/
h and 29,000 Btu/h, and whether DOE
should consider including a
representative single-packaged refrigeration system with capacity in this range.
To conduct an engineering analysis for wine cellar refrigeration systems, DOE seeks information on the size and capacities of the most representative units on the market. DOEs initial research into wine cellar refrigeration systems indicates that the capacity for most single-package and matched-pair units ranges from 1,000 Btu/h to 18,000
Btu/h, with very few units between 13,000 Btu/h and 18,000 Btu/hr.
Additionally, DOE received information from AHRI in 2019 listing capacity, AWEF, condenser fan power, and compressor type for wine cellar refrigeration systems.37
Issue 36: DOE requests comment on if the capacity, AWEF, condenser fan power, and compressor types provided by AHRI are representative of the market for single-package and matchedpair wine cellar refrigeration systems.
DOE also seeks information on the availability and prevalence of wine cellar refrigeration systems between 13,000 and 18,000 Btu/h for walk-in wine cellars with a square footage of 3,000 square feet or less.

D. Significant Savings of Energy In determining whether a proposed energy conservation standard is economically justified, DOE analyzes, among other things, the potential economic impact on consumers, manufacturers, and the Nation. DOE
seeks comment on whether there are economic barriers to the adoption of more stringent energy conservation standards. DOE also seeks comment and data on any other aspects of its economic justification analysis from the June 2014 ECS final rule and July 2017
ECS final rule that may indicate whether a more stringent energy conservation standard would be economically justified or cost effective.

While DOE is particularly interested in comment, information, and data on the following issues, this request for information is not strictly limited to them.
1. Markups AnalysisDistribution Channels DOE derives customer prices based on manufacturer markups, retailer markups, distributor markups, contractor markups where appropriate, and sales taxes. In deriving these markups, DOE determines the major distribution channels for product sales, the markup associated with each party in each distribution channel, and the existence and magnitude of differences between markups for baseline products baseline markups and higherefficiency products incremental markups. The identified distribution channels i.e., how the products are distributed from the manufacturer to the consumer and estimated relative sales volumes through each channel are used in generating end-user price inputs for the life-cycle cost LCC analysis and national impact analysis NIA.
In the June 2014 ECS final rule and July 2017 ECS final rule, DOE defined the distribution channels for WICFs and estimated their respective shares of shipments as: 1 Direct to customer sales, through national accounts or contractors; 2 refrigeration wholesalers to consumers; 3 Original Equipment Manufacturers OEM to consumers the OEM distribution channel primarily represents manufacturers of WICF
refrigeration systems who may also install and sell entire WICF refrigeration units; 4 contractors who primarily install WICF envelope components panels and doors; and 5 refrigeration equipment distributors of panels and non-display doors. WICF distribution channels evaluated in DOEs previous rulemakings are summarized in Table II.16.
