Rulemaking for Automatic Commercial Ice Makers Energy Conservation Standard
The purpose of this rulemaking is to: 1) establish energy conservation standards for cube ice makers with capacities between 50 and 2,500 pounds per 24-hour period; and 2) determine whether to establish energy conservation standards for additional types of automatic commercial ice makers as well as ice makers with capacities greater than 2,500 pounds per 24-hour period. The existing standards were prescribed by the Energy Policy Act of 2005 (EPACT 2005) amendments to the Energy Policy and Conservation Act (EPCA). EPACT 2005 also authorizes the Department of Energy (DOE) to issue standards for other types of automatic commercial ice makers.
The U.S. Department of Energy ("DOE" or "the Department") is currently conducting a rulemaking to update the energy conservation standard for automatic commercial ice makers (ACIM). As part of this rulemaking, DOE carried out detailed energy modeling using the FREEZE simulation program ("FREEZE" or "the model") to verify and extrapolate the results of the reverse engineering process. FREEZE is an energy model that simulates the performance of both batch and continuous ice makers. It calculates thermal loads required to cool incoming water and freeze ice, and accounts for compressor power input based on detailed compressor performance information. During the NOPR analysis, DOE made several adjustments to the model’s calculations based on comments and available information. The key outputs of the model used in the rulemaking’s engineering analysis are presented in the technical support documents. See http://www.regulations.gov/#!documentDetail;D=EERE-2010-BT-STD-0037-0061.

In order to facilitate additional review of the model and
gather additional feedback and data from interested parties, DOE held a public
meeting on June 19th, 2014 to discuss the use of the model in the engineering
analysis.The comments received since
publication of the March 2014 NOPR, including those received at the April 2014
and the June 2014 public meetings, provided inputs which led DOE to revise its
analyses and publish a Federal Register Notice of Data Availability
(NODA). 79FR54215 (September 11, 2014). Stakeholders also submitted additional information
to DOE’s consultant pursuant to non-disclosure agreements regarding efficiency
gains and costs of potential design options. In addition, DOE reviewed
additional market data, including published ratings of available ice makers, to
recalibrate its engineering analysis. Generally, the revisions include
modifications of inputs for its engineering
analysis, life-cycle cost analysis,
national impact analysis, adjustment of
its energy model calculations, and more thorough consideration of
size-constrained ice maker applications. The analysis revisions addressing
size-constrained applications included development of engineering analyses for
three size-constrained equipment categories and restructuring of the life-cycle
cost and national impact analyses to consider size constraints for applicable
equipment classes. Additional information includes trial standard level charts and a file documenting the changes described above.
DOE held a public meeting on June 19, 2014 from 9 a.m. to 4 p.m., at the U.S. Department of Energy, Forrestal Building, Room 8E-089, 1000 Independence Avenue, SW., Washington, DC 20585.

*After a regulatory action has been completed, Executive Order 12866 requires agencies to identify the substantive changes between the draft submitted to Office of Information and Regulatory Affairs (OIRA) for review and the action subsequently announced, and to identify those changes made at the suggestion or recommendation of OIRA.
There are no related rulemakings.
The EPACT 2005 amendments to EPCA require DOE to conduct two cycles of rulemakings to determine whether to amend the standards for automatic commercial ice makers—both those prescribed by EPACT 2005 and those prescribed by DOE. (42 U.S.C. 6313(d)) In the first cycle, the subject of this rulemaking, DOE must publish a final rule establishing such amended standards by January 1, 2015, if DOE determines to amend the standards. (42 U.S.C. 6313(d)(3)(A))
