Issue 6: DOE requests annual sales data in units shipped or linear feet of shipped units of CRE from 2014 to 2020, disaggregated by equipment class.
DOE also seeks feedback on how the breakdowns by equipment class presented in Table II.1 of this document and the annual shipments estimates shown in Table II.2 of this document compare to the actual shipments in those years. If disaggregated shipments data are not available at the equipment class level, DOE requests shipments data at any broader available category.
Issue 7: DOE also seeks historical and current shipments data on any additional CRE categories under consideration for potential standards i.e., refrigerated salad bars, buffet tables, and preparation tables; soliddoor equipment for pull-down temperature applications; chef bases or griddle stands; high-temperature CRE;
and CRE with dedicated remote condensing units.
2. National Energy Savings The purpose of the national impact analysis NIA is to estimate aggregate impacts of potential new and/or amended efficiency standards at the jbell on DSKJLSW7X2PROD with PROPOSALS

national level in terms of national energy savings NES and net present value NPV, discussed in section II.D.4 of this document of the total consumer benefits. The NIA considers lifetime impacts of potential standards on equipment shipped in a 30-year period that begins with the expected compliance date for new and/or amended standards.
DOE measures savings of potential standards relative to a no-newstandards case that reflects conditions without new and/or amended standards, and uses current efficiency market shares to characterize the no-newstandards case equipment efficiency distribution. By accounting for consumers who already purchase more efficient CRE, DOE avoids overstating the potential benefits from potential standards. In the March 2014 Final Rule, DOE developed efficiency trends for CRE in the no-new-standards case and the standards cases assuming that the market would move over time to adopt ENERGY STAR rated equipment.
To estimate the impact that energy efficiency standards would have in the year compliance becomes required, DOE

used a roll-up scenario. A roll-up scenario assumes that equipment efficiencies in the no-new-standards case, which do not meet the standard level under consideration, would roll up to meet the new efficiency standard level. Equipment shipments at efficiencies above the efficiency standard level under consideration are not affected. See chapter 10 of the March 2014 Final Rule TSD for details on this approach.
Issue 8: DOE seeks input on whether any market or technology changes would warrant a different approach to develop CRE efficiency trends than the one followed in the March 2014 Final Rule. DOE requests any relevant data that could be used to project efficiency trends for CRE.
C. Technological Feasibility 1. Technology Options During the March 2014 Final Rule, DOE considered a number of technology options that manufacturers could use to reduce energy consumption in CRE.
Table II.3 includes a complete list of those technology options considered in developing the March 2014 Final Rule.
