The U.S. Department of Energy ("DOE") proposes to amend the test procedures for walk-in coolers and walk-in freezers to harmonize with updated industry standards, revise the test methods to more fully represent field energy use, and better account for the range of walk-in cooler and walk-in freezer component equipment designs. DOE also proposes to revise certain definitions applicable to walk-ins. DOE is seeking comment from interested parties on the proposal and announcing a public meeting to collect comments and data on its proposal. (...)

Energy Conservation Program: Energy Conservation Standards for Commercial Water Heating Equipment: The Energy Policy and Conservation Act, as amended ("EPCA"), prescribes energy conservation standards for certain commercial and industrial equipment, including commercial water heaters, hot water supply boilers, and unfired hot water storage tanks (hereinafter referred to as "commercial water heating (CWH) equipment"). EPCA requires the U.S. Department of Energy ("DOE") to periodically determine whether more-stringent standards for CWH equipment would be technologically feasible and economically justified, and would result in significant energy savings. In this notice of proposed rulemaking ("NOPR"), DOE proposes to amend the standards for certain classes of CWH equipment for which DOE has tentatively determined there is clear and convincing evidence to support more-stringent standards. Additionally, DOE is proposing to codify standards for electric instantaneous CWH equipment from EPCA into the Code of Federal Regulations ("CFR"). (...)

The U.S. Department of Energy ("DOE") proposes to amend the test procedure for commercial and industrial pumps ("pumps") to harmonize with updated industry standards, to expand the scope of clean water pumps covered by this test procedure, and to revise calculation methods for pumps sold with motors and controls to better represent field energy use. (...)

Energy Conservation Program: Energy Conservation Standards for Consumer Furnaces: The Energy Policy and Conservation Act, as amended ("EPCA"), prescribes energy conservation standards for various consumer products and certain commercial and industrial equipment, including consumer furnaces. EPCA also requires the Department of Energy ("DOE" or "the Department") to periodically determine whether more-stringent, amended standards would be technologically feasible and economically justified, and would result in significant energy savings. In this notice of proposed rulemaking ("NOPR"), DOE proposes amended energy conservation standards for non-weatherized gas furnaces and mobile home gas furnaces (...)

The U.S. Department of Energy ("DOE") proposes to amend the test procedures for consumer boilers to incorporate by reference the latest version of the industry standards currently referenced in the Federal test procedure. DOE proposes to relocate the test procedure in a new appendix separate from the residential furnace test procedure. DOE also proposes to remove an extraneous definition from its regulatory definitions. (...)

Energy Conservation Program: Test Procedure for Portable Air Conditioners: The U.S. Department of Energy ("DOE") proposes to amend the test procedure for portable air conditioners ("portable ACs") to incorporate a measure of variable-speed portable AC performance and make minor clarifying edits. DOE also proposes a new test procedure to improve representativeness for all configurations of portable ACs, which relies on a substantively different measure of cooling capacity and energy consumption compared to the current portable AC test procedure. (...)

Energy Conservation Program: Energy Conservation Standards for Single Package Vertical Units: The Energy Policy and Conservation Act, as amended (EPCA), prescribes energy conservation standards for various consumer products and certain commercial and industrial equipment, including single package vertical air conditioners (SPVACs) and single package vertical heat pumps (SPVHPs), collectively referred to as single package vertical units (SPVUs). EPCA also requires the U.S. Department of Energy (DOE) to periodically review standards. In this notice of proposed rulemaking (NOPR); notification of proposed determination (NOPD), DOE proposes to amend the current energy conservation standards for SPVUs such that the existing standard levels would be based on a new cooling efficiency metric of Integrated Energy Efficiency Ratio (IEER) for SPVACs and SPVHPs, and the current heating efficiency metric of Coefficient of Performance (COP) for SPVHPs (but without any increase in stringency) (...)

Energy Conservation Program: Test Procedure for Ceiling Fan Light Kits: The U.S. Department of Energy ("DOE") proposes to amend the test procedure for ceiling fan light kits ("CFLKs"). DOE proposes to update references to industry standards to their latest versions and incorporate industry standards necessary for executing the test; to allow for the use of a goniophotometer; to revise definitions regarding CFLKs with solid-state lighting ("SSL") light sources to clarify the scope and test methods for CFLKs; and to remove obsolete provisions. (...)

Energy Conservation Program: Test Procedure for Refrigerated Bottled or Canned Beverage Vending Machines: The U.S. Department of Energy ("DOE") proposes to amend the test procedures for refrigerated bottled or canned beverage vending machines ("BVMs") to reference the latest version of the industry standard. DOE also proposes to provide setup instructions for non- beverage shelves, update the lowest application product temperature definition and instructions, require testing of coin and bill payment mechanisms if shipped with the BVM (but not until the compliance date of any amended energy conservation standards), specify setup instructions for leak mitigation controls, and remove an obsolete version of the test procedure. (...)

Energy Conservation Program: Test Procedure for Dehumidifiers: The U.S. Department of Energy ("DOE") proposes to amend the test procedure for dehumidifiers. The proposed amendments would reference the current version of an applicable industry standard; allow the rating test period to be 2 or 6 hours; permit the use of a sampling tree in conjunction with an aspirating psychrometer for testing a dehumidifier with a single process air intake grille; and specify for dehumidifiers with network capabilities that all network functions must be disabled throughout testing.
