For distribution transformers, the basic model number or kVA grouping model number (depending on the certification method) for each brand must be submitted. For commercial HVAC, WH, and refrigeration equipment, an individual manufacturer model number may be identified as a “private model number” if it meets the requirements of §429.7(b). (7) Whether the submission is for a new model, a discontinued model, a correction to a previously submitted model, data on a carryover model, or a model that has been found in violation of a voluntary industry certification program; (8) The test sample size (i.e., number of units tested for each basic model). Manufacturers must enter “0” if an AEDM was used in lieu of testing; (9) The certifying party's U.S. Customs and Border Protection (CBP) importer identification numbers assigned by CBP pursuant to 19 CFR 24.5, if applicable; (10) Whether certification is based upon any waiver of test procedure requirements under §430.27 or §431.401 of this chapter and the date(s) of such waiver(s); (11) Whether certification is based upon any exception relief from an applicable energy conservation standard and the date such relief was issued by DOE's Office of Hearings and Appeals; (12) If the test sample size is listed as “0” to indicate the certification is based upon the use of an alternate way of determining measures of energy conservation, identify the method used for determining measures of energy conservation (such as “AEDM,” “ARM,” or linear interpolation) and the approval date, if applicable, of any such alternate rating, testing, or efficiency determination method. Manufacturers of commercial packaged boilers, commercial water heating equipment, commercial refrigeration equipment and commercial HVAC equipment, must provide the manufacturer's designation (name or other identifier) of the AEDM used; and (13) Product specific information listed in §§429.14 through 429.58 of this chapter. (c) Compliance statement. The compliance statement required by paragraph (b) of this section shall include the date, the name of the company official signing the statement, and his or her signature, title, address, telephone number, and facsimile number and shall certify that: (1) The basic model(s) complies with the applicable energy conservation standard(s); (2) All required testing has been conducted in conformance with the applicable test requirements prescribed in parts 429, 430 and 431, as appropriate, or in accordance with the terms of an applicable test procedure waiver; (3) All information reported in the certification report is true, accurate, and complete; and (4) The manufacturer is aware of the penalties associated with violations of the Act, the regulations thereunder, and 18 U.S.C. 1001 which prohibits knowingly making false statements to the Federal Government. (d) Annual filing. All data required by paragraphs (a) through (c) shall be submitted to DOE annually, on or before the following dates:
(e) New model filing. (1) In addition to the annual filing schedule in paragraph (d) of this section, any new basic models must be certified pursuant to paragraph (a) of this section before distribution in commerce. A modification to a model that increases the model's energy or water consumption or decreases its efficiency resulting in rerating must be certified as a new basic model pursuant to paragraph (a) of this section. (2) For general service fluorescent lamps or incandescent reflector lamps: Prior to or concurrent with the distribution of a new basic model each manufacturer shall submit an initial certification report listing the basic model number, lamp wattage, and date of first manufacture (i.e., production date) for that basic model. The certification report must also state how the manufacturer determined that the lamp meets or exceeds the energy conservation standards, including a description of any testing or analysis the manufacturer performed. Manufacturers of general service fluorescent lamps and incandescent reflector lamps shall submit the certification report required by paragraph (b) of this section within one year after the first date of new model manufacture. (3) For distribution transformers, the manufacturer shall submit all information required in paragraphs (b) and (c) of this section for the new basic model, unless the manufacturer has previously submitted to the Department a certification report for a basic model of distribution transformer that is in the same kVA grouping as the new basic model. (f) Discontinued model filing. When production of a basic model has ceased and it is no longer being sold or offered for sale by the manufacturer or private labeler, the manufacturer shall report this discontinued status to DOE as part of the next annual certification report following such cessation. For each basic model, the report shall include the information specified in paragraphs (b)(1) through (b)(7) of this section. (g) Third party submitters. A manufacturer may elect to use a third party to submit the certification report to DOE (for example, a trade association, independent test lab, or other authorized representative, including a private labeler acting as a third party submitter on behalf of a manufacturer); however, the manufacturer is responsible for submission of the certification report to DOE. DOE may refuse to accept certification reports from third party submitters who have failed to submit reports in accordance with the rules of this part. The third party submitter must complete the compliance statement as part of the certification report. Each manufacturer using a third party submitter must have an authorization form on file with DOE. The authorization form includes a compliance statement, specifies the third party authorized to submit certification reports on the manufacturer's behalf and provides the contact information and signature of a company official. (h) Method of submission. Reports required by this section must be submitted to DOE electronically at http://www.regulations.doe.gov/ccms (CCMS). A manufacturer or third party submitter can find productspecific templates for each covered product or covered equipment with certification requirements online at https://www.regulations.doe.gov/ccms/templates.html. Manufacturers and third party submitters must submit a registration form, signed by an officer of the company, in order to obtain access to CCMS. (i) Compliance dates.

[79 FR 25504, May 5, 2014] §429.70 Alternative methods for determining energy efficiency and energy use.Link to an amendment published at 79 FR 40565, July 11, 2014. (a) General applicability of an AEDM. A manufacturer of covered products or covered equipment explicitly authorized to use an AEDM in §§429.14 through 429.54 may not distribute any basic model of such equipment in commerce unless the manufacturer has determined the energy efficiency of the basic model, either from testing the basic model in conjunction with DOE's certification sampling plans and statistics or from applying an alternative method for determining energy efficiency or energy use (AEDM) to the basic model, in accordance with the requirements of this section. In instances where a manufacturer has tested a basic model, the manufacturer may not knowingly use an AEDM to overrate the efficiency (or underrate the consumption) of the model. (b) Testing. Testing for each covered product or covered equipment must be done in accordance with the sampling plan provisions established in §429.11 and the testing procedures in parts 430 and 431 of this chapter. (c) Alternative efficiency determination method (AEDM) for commercial HVAC (includes commercial warm air furnaces and commercial packaged boilers), WH, and refrigeration equipment—(1) Criteria an AEDM must satisfy. A manufacturer may not apply an AEDM to a basic model to determine its efficiency pursuant to this section unless: (i) The AEDM is derived from a mathematical model that estimates the energy efficiency or energy consumption characteristics of the basic model as measured by the applicable DOE test procedure; (ii) The AEDM is based on engineering or statistical analysis, computer simulation or modeling, or other analytic evaluation of performance data; and (iii) The manufacturer has validated the AEDM, in accordance with paragraph (c)(2) of this section with basic models that meet the current Federal energy conservation standards. (2) Validation of an AEDM. Before using an AEDM, the manufacturer must validate the AEDM's accuracy and reliability as follows: (i) The manufacturer must select at least the minimum number of basic models for each validation class specified in paragraph (c)(2)(iv) of this section to which the particular AEDM applies. Using the AEDM, calculate the energy use or efficiency for each of the selected basic models. Test a single unit of each selected basic model in accordance with paragraph (c)(2)(iii) of this section. Compare the results from the single unit test and the AEDM energy use or efficiency output according to paragraph (c)(2)(ii) of this section. The manufacturer is responsible for ensuring the accuracy and reliability of the AEDM. (ii) Individual model tolerances. (A) For those covered products with an energyefficiency metric, the predicted efficiency for each model calculated by applying the AEDM may not be more than five percent greater than the efficiency determined from the corresponding test of the model. (B) For those covered products with an energyconsumption metric, the predicted energy consumption for each model, calculated by applying the AEDM, may not be more than five percent less than the energy consumption determined from the corresponding test of the model. (C) For all covered products, the predicted energy efficiency or consumption for each model calculated by applying the AEDM must meet or exceed the applicable federal energy conservation performance standard. (iii) Additional test unit requirements. (A) Each AEDM must be supported by test data obtained from physical tests of current models; and (B) Test results used to validate the AEDM must meet or exceed current, applicable Federal standards as specified in part 431 of this chapter; and (C) Each test must have been performed in accordance with the DOE test procedure specified in parts 430 or 431 of this chapter or test procedure waiver for which compliance is required at the time the basic model is distributed in commerce. (iv) Validation classes.
^{1}The minimum number of tests indicated above must be comprised of a transparent model, a solid model, a vertical model, a semivertical model, a horizontal model, and a serviceoverthe counter model, as applicable based on the equipment offering. However, manufacturers do not need to include all types of these models if it will increase the minimum number of tests that need to be conducted. (3) AEDM records retention requirements. If a manufacturer has used an AEDM to determine representative values pursuant to this section, the manufacturer must have available upon request for inspection by the Department records showing: (i) The AEDM, including the mathematical model, the engineering or statistical analysis, and/or computer simulation or modeling that is the basis of the AEDM; (ii) Product information, complete test data, AEDM calculations, and the statistical comparisons from the units tested that were used to validate the AEDM pursuant to paragraph (c)(2) of this section; and (iii) Product information and AEDM calculations for each basic model to which the AEDM has been applied. (4) Additional AEDM requirements. If requested by the Department and at DOE's discretion, the manufacturer must perform at least one of the following: (i) Conduct simulations before representatives of the Department to predict the performance of particular basic models of the product to which the AEDM was applied; (ii) Provide analyses of previous simulations conducted by the manufacturer; or (iii) Conduct certification testing of basic models selected by the Department. (5) AEDM verification testing. DOE may use the test data for a given individual model generated pursuant to §429.104 to verify the certified rating determined by an AEDM as long as the following process is followed: (i) Selection of units. DOE will obtain units for test from retail, where available. If units cannot be obtained from retail, DOE will request that a unit be provided by the manufacturer; (ii) Lab requirements. DOE will conduct testing at an independent, thirdparty testing facility of its choosing. In cases where no thirdparty laboratory is capable of testing the equipment, it may be tested at a manufacturer's facility upon DOE's request. (iii) Manufacturer participation. [Reserved] (iv) Testing. At no time during verification testing may the lab and the manufacturer communicate without DOE authorization. All verification testing will be conducted in accordance with the applicable DOE test procedure, as well as each of the following to the extent that they apply: (A) Any active test procedure waivers that have been granted for the basic model; (B) Any test procedure guidance that has been issued by DOE; (C) The installation and operations manual that is shipped with the unit; (D) Any additional information that was provided by the manufacturer at the time of certification (prior to DOE obtaining the unit for test); and (E) If during test setup or testing, the lab indicates to DOE that it needs additional information regarding a given basic model in order to test in accordance with the applicable DOE test procedure, DOE may organize a meeting between DOE, the manufacturer and the lab to provide such information. (v) Failure to meet certified rating. If a model tests worse than its certified rating by an amount exceeding the tolerance prescribed in paragraph (c)(5)(vi) of this section, DOE will notify the manufacturer. DOE will provide the manufacturer with all documentation related to the test set up, test conditions, and test results for the unit. Within the timeframe allotted by DOE, the manufacturer may then: (A) Present all claims regarding testing validity; and (B) If the manufacturer was not on site for the initial test setup, request a retest of the previously tested unit with manufacturer and DOE representatives onsite for the test setup. DOE will not conduct the retest using a different unit of the same basic model unless DOE and the manufacturer determine it is necessary based on the test results, claims presented, and DOE regulations. (vi) Tolerances. (A) For consumption metrics, the result from a DOE verification test must be less than or equal to the certified rating × (1 + the applicable tolerance). (B) For efficiency metrics, the result from a DOE verification test must be greater than or equal to the certified rating × (1 − the applicable tolerance).
(vii) Invalid rating. If, following discussions with the manufacturer and a retest where applicable, DOE determines that the verification testing was conducted appropriately in accordance with the DOE test procedure, DOE will issue a determination that the rating for the model is invalid. The manufacturer must elect, within 15 days, one of the following to be completed in a time frame specified by DOE, which is never to exceed 180 days: (A) Rerate and recertify the model based on DOE's test data alone; or (B) Discontinue the model through the certification process; or (C) Conduct additional testing and rerate and recertify the basic model based on all test data collected, including DOE's test data. (viii) AEDM use. (A) If DOE has determined that a manufacturer made invalid ratings on two or more models rated using the same AEDM within a 24 month period, the manufacturer must take the action listed in the table corresponding to the number of invalid certified ratings. The twentyfour month period begins with a DOE determination that a rating is invalid through the process outlined above. Additional invalid ratings apply for the purposes of determining the appropriate consequences if the subsequent determination(s) is based on selection of a unit for testing within the twentyfour month period (i.e., subsequent determinations need not be made within 24 months).
^{1}A manufacturer may discuss with DOE's Office of Enforcement whether existing test data on different basic models within the validation classes to which that specific AEDM was applied may be used to meet this requirement. ^{2}The “same AEDM” means a computer simulation or mathematical model that is identified by the manufacturer at the time of certification as having been used to rate a model or group of models. ^{3}The twentyfour month period begins with a DOE determination that a rating is invalid through the process outlined above. Additional invalid ratings apply for the purposes of determining the appropriate consequences if the subsequent determination(s) is based on testing of a unit that was selected for testing within the twentyfour month period (i.e., subsequent determinations need not be made within 24 months). (B) If, as a result of eight or more invalid ratings, a manufacturer has lost the privilege of using an AEDM for rating, the manufacturer may regain the ability to use an AEDM by: (1) Investigating and identifying cause(s) for failures; (2) Taking corrective action to address cause(s); (3) Performing six new tests per validation class, a minimum of two of which must be performed by an independent, thirdparty laboratory to validate the AEDM; and (4) Obtaining DOE authorization to resume use of the AEDM. (d) Alternative efficiency determination method for distribution transformers—A manufacturer may use an AEDM to determine the efficiency of one or more of its untested basic models only if it determines the efficiency of at least five of its other basic models (selected in accordance with paragraph (d)(3) of this section) through actual testing. (1) Criteria an AEDM must satisfy. (i) The AEDM has been derived from a mathematical model that represents the electrical characteristics of that basic model; (ii) The AEDM is based on engineering and statistical analysis, computer simulation or modeling, or other analytic evaluation of performance data; and (iii) The manufacturer has substantiated the AEDM, in accordance with paragraph (d)(2) of this section, by applying it to, and testing, at least five other basic models of the same type, i.e., lowvoltage drytype distribution transformers, mediumvoltage drytype distribution transformers, or liquidimmersed distribution transformers. (2) Substantiation of an AEDM. Before using an AEDM, the manufacturer must substantiate the AEDM's accuracy and reliability as follows: (i) Apply the AEDM to at least five of the manufacturer's basic models that have been selected for testing in accordance with paragraph (d)(3) of this section, and calculate the power loss for each of these basic models; (ii) Test at least five units of each of these basic models in accordance with the applicable test procedure and §429.47, and determine the power loss for each of these basic models; (iii) The predicted total power loss for each of these basic models, calculated by applying the AEDM pursuant to paragraph (d)(2)(i) of this section, must be within plus or minus five percent of the mean total power loss determined from the testing of that basic model pursuant to paragraph (d)(2)(ii) of this section; and (iv) Calculate for each of these basic models the percentage that its power loss calculated pursuant to paragraph (d)(2)(i) of this section is of its power loss determined from testing pursuant to paragraph (d)(2)(ii) of this section, compute the average of these percentages, and that calculated average power loss, expressed as a percentage of the average power loss determined from testing, must be no less than 97 percent and no greater than 103 percent. (3) Additional testing requirements. (i) A manufacturer must select basic models for testing in accordance with the following criteria: (A) Two of the basic models must be among the five basic models with the highest unit volumes of production by the manufacturer in the prior year, or during the prior 12calendarmonth period beginning in 2003,1 whichever is later; 1When identifying these five basic models, any basic model that does not comply with Federal energy conservation standards for distribution transformers that may be in effect shall be excluded from consideration. (B) No two basic models should have the same combination of power and voltage ratings; and (C) At least one basic model should be singlephase and at least one should be threephase. (ii) In any instance where it is impossible for a manufacturer to select basic models for testing in accordance with all of these criteria, the criteria shall be given priority in the order in which they are listed. Within the limits imposed by the criteria, basic models shall be selected randomly. (4) Subsequent verification of an AEDM. (i) Each manufacturer that has used an AEDM under this section shall have available for inspection by the Department of Energy records showing: (A) The method or methods used; (B) The mathematical model, the engineering or statistical analysis, computer simulation or modeling, and other analytic evaluation of performance data on which the AEDM is based; (C) Complete test data, product information, and related information that the manufacturer has generated or acquired pursuant to paragraph (d)(4) of this section; and (D) The calculations used to determine the efficiency and total power losses of each basic model to which the AEDM was applied. (ii) If requested by the Department, the manufacturer must perform at least one of the following: (A) Conduct simulations to predict the performance of particular basic models of distribution transformers specified by the Department; (B) Provide analyses of previous simulations conducted by the manufacturer; (C) Conduct sample testing of basic models selected by the Department; or (D) Conduct a combination of these. (e) Alternate Rating Method (ARM) for residential splitsystem central air conditioners and heat pumps— (1) Criteria an ARM must satisfy. The basis of the ARM referred to in §429.16(a)(2)(ii) for residential central air conditioners and heat pumps must be a representation of the test data and calculations of a mechanical vaporcompression refrigeration cycle. The major components in the refrigeration cycle must be modeled as “fits” to manufacturer performance data or by graphical or tabular performance data. Heat transfer characteristics of coils may be modeled as a function of face area, number of rows, fins per inch, refrigerant circuitry, airflow rate and enteringair enthalpy. Additional performancerelated characteristics to be considered may include type of expansion device, refrigerant flow rate through the expansion device, power of the indoor fan and cyclicdegradation coefficient. Ratings for untested combinations must be derived from the ratings of a combination tested in accordance with §429.16(a)(2)(i). The seasonal energy efficiency ratio (SEER) and/or heating seasonal performance factor (HSPF) ratings for an untested combination must be set equal to or less than the lower of the SEER and/or HSPF calculated using the applicable DOEapproved alternative rating method (ARM). If the method includes an ARM/simulation adjustment factor(s), determine the value(s) of the factors(s) that yield the best match between the SEER/HSPF determined using the ARM versus the SEER/HSPF determined from testing in accordance with §429.16(a)(2)(i). Thereafter, apply the ARM using the derived adjustment factor(s) only when determining the ratings for untested combinations having the same outdoor unit. (2) Approval of an ARM. (i) Manufacturers who elect to use an ARM for determining measures of energy consumption under §429.16(a)(2)(ii)(B)(1) and paragraph (e)(1) of this section must submit a request for DOE to review the ARM. Send the request to: U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy, Building Technologies Program (EE2J), Attention: Alternative Rating Methods (ARM) for Certification and Compliance, Forrestal Building, 1000 Independence Avenue, SW., Washington, DC 205850121. (ii) Each request to DOE for approval of an ARM must include: (A) The name, mailing address, telephone number, and email address of the official representing the manufacturer. (B) Complete documentation of the alternative rating method to allow DOE to evaluate its technical adequacy. The documentation must include a description of the methodology, state any underlying assumptions, and explain any correlations. The documentation should address how the method accounts for the cyclicdegradation coefficient, the type of expansion device, and, if applicable, the indoor fanoff delay. The requestor must submit any computer programs—including spreadsheets—having less than 200 executable lines that implement the ARM. Longer computer programs must be identified and sufficiently explained, as specified above, but their inclusion in the initial submittal package is optional. Applicability or limitations of the ARM (e.g., only covers singlespeed units when operating in the cooling mode, covers units with rated capacities of 3 tons or less, not applicable to the manufacturer's product line of nonducted systems) must be stated in the documentation. (C) Complete test data from laboratory tests on four mixed (i.e., nonhighestsalesvolume combination) systems per each ARM. (1) The four mixed systems must include four different indoor units and at least two different outdoor units. A particular model of outdoor unit may be tested with up to two of the four indoor units. The four systems must include two lowcapacity mixed systems and two highcapacity mixed systems. The lowcapacity mixed systems may have any capacity. The rated capacity of each highcapacity mixed system must be at least a factor of two higher than its counterpart lowcapacity mixed system. The four mixed systems must meet the applicable energy conservation standard in §430.32(c) in effect at the time of the rating. (2) The four indoor units must come from at least two different coil families, with a maximum of two indoor units coming from the same coil family. Data for two indoor units from the same coil family, if submitted, must come from testing with one of the “lowcapacity mixed systems” and one of the “highcapacity mixed systems.” A mixed system indoor coil may come from the same coil family as the highestsalesvolumecombination indoor unit (i.e., the “matched” indoor unit) for the particular outdoor unit. Data on mixed systems where the indoor unit is now obsolete will be accepted towards the ARMvalidation submittal requirement if it is from the same coil family as other indoor units still in production. (3) The first two sentences of paragraph (e)(2)(ii)(C)(2) of this section do not apply if the manufacturer offers indoor units from only one coil family. In this case only, all four indoor coils must be selected from this one coil family. If approved, the ARM will be specifically limited to applications for this one coil family. (D) All product information on each mixed system indoor unit, each matched system indoor unit, and each outdoor unit needed to implement the proposed ARM. The calculated ratings for the four mixed systems, as determined using the proposed ARM, must be provided along with any other related information that will aid the verification process. (E) If request for approval is for an updated ARM, manufacturers must identify modifications made to the ARM since the last submittal, including any ARM/simulation adjustment factor(s) added since the ARM was last approved by DOE. (iii) Approval must be received from the Department to use the ARM before the ARM may be used for rating splitsystem central air conditioners and heat pumps. If a manufacturer has a DOEapproved ARM for products also distributed in commerce by a private labeler, the ARM may also be used by the private labeler for rating these products. Once an ARM is approved, DOE may contact a manufacturer to learn if their ARM has been modified in any way and to verify that the ARM is being applied as approved. DOE will give followup priority to individual combinations having questionably high ratings (e.g., a coilonly system having a rating that exceeds the rating of a coilonly highest sales volume combination by more than 6 percent). (3) Changes to DOE's regulations requiring reapproval of an ARM. Manufacturers who elect to use an ARM for determining measures of energy consumption under §429.16(a)(2)(ii)(B)(1) and paragraph (e)(1) of this section must submit a request for DOE to review the ARM when: (i) DOE amends the energy conservation standards as specified in §430.32 for residential central air conditioners and heat pumps. In this case, any testing and evidence required under paragraph (e)(2) of this section shall be developed with units that meet the amended energy conservation standards specified in §430.32. Reapproval for the ARM must be obtained before the compliance date of amended energy conservation standards. (ii) DOE amends the test procedure for residential air conditioners and heat pumps as specified in appendix M to subpart B of part 430. Reapproval for the ARM must be obtained before the compliance date of amended test procedures. (4) Manufacturers that elect to use an ARM for determining measures of energy consumption under §429.16(a)(2)(ii)(B)(1) and paragraph (e)(1) of this section must regularly either subject a sample of their units to independent testing, e.g., through a voluntary certification program, in accordance with the applicable DOE test procedure, or have the representations reviewed by an independent stateregistered professional engineer who is not an employee of the manufacturer. The manufacturer may continue to use the ARM only if the testing establishes, or the registered professional engineer certifies, that the results of the ARM accurately represent the energy consumption of the unit(s). Any proposed change to the alternative rating method must be approved by DOE prior to its use for rating. (5) Manufacturers who choose to use computer simulation or engineering analysis for determining measures of energy consumption under §429.16(a)(2)(ii)(B)(1) and paragraphs (e)(1) through (e)(4) of this section must permit representatives of the Department of Energy to inspect for verification purposes the simulation method(s) and computer program(s) used. This inspection may include conducting simulations to predict the performance of particular outdoor unit “indoor” unit combinations specified by DOE, analysis of previous simulations conducted by the manufacturer, or both. (f) Alternative efficiency determination method (AEDM) for walkin refrigeration equipment— (1) Criteria an AEDM must satisfy. A manufacturer may not apply an AEDM to a basic model to determine its efficiency pursuant to this section unless: (i) The AEDM is derived from a mathematical model that estimates the energy efficiency or energy consumption characteristics of the basic model as measured by the applicable DOE test procedure; (ii) The AEDM is based on engineering or statistical analysis, computer simulation or modeling, or other analytical evaluation of performance data; and (iii) The manufacturer has validated the AEDM, in accordance with paragraph (f)(2) of this section.

Test a single unit of each basic model in accordance with paragraph (f)(2)(iii) of this section. Using the AEDM, calculate the energy use or energy efficiency for each of the selected basic models. Compare the results from the single unit test and the AEDM output according to paragraph (f)(2)(ii) of this section. The manufacturer is responsible for ensuring the accuracy and repeatability of the AEDM. (ii) Individual model tolerances. (A) The predicted efficiency for each model calculated by applying the AEDM may not be more than five percent greater than the efficiency determined from the corresponding test of the model. (B) The predicted energy efficiency for each model calculated by applying the AEDM must meet or exceed the applicable federal energy conservation standard. (iii) Additional test unit requirements. (A) Each AEDM must be supported by test data obtained from physical tests of current models; and (B) Test results used to validate the AEDM must meet or exceed current, applicable Federal standards as specified in part 431 of this chapter; (C) Each test must have been performed in accordance with the applicable DOE test procedure with which compliance is required at the time the basic model is distributed in commerce; and (D) For rating WICF refrigeration system components, an AEDM may not simulate or model portions of the system that are not required to be tested by the DOE test procedure. That is, if the test results used to validate the AEDM are for either a unit cooler only or a condensing unit only, the AEDM must estimate the system rating using the nominal values specified in the DOE test procedure for the other part of the refrigeration system. (iv) WICF refrigeration validation classes.
^{1}AEDMs validated for dedicated condensing, medium temperature, outdoor systems may be used to determine representative values for dedicated condensing, medium temperature, indoor systems, and additional validation testing is not required. AEDMs validated for only dedicated condensing, medium temperature, indoor systems may not be used to determine representative values for dedicated condensing, medium temperature, outdoor systems. ^{2}AEDMs validated for dedicated condensing, low temperature, outdoor systems may be used to determine representative values for dedicated condensing, low temperature, indoor systems, and additional validation testing is not required.

AEDMs validated for only low temperature, indoor condensing units may not be used to determine representative values for low temperature, outdoor condensing units. (3) AEDM records retention requirements. If a manufacturer has used an AEDM to determine representative values pursuant to this section, the manufacturer must have available upon request for inspection by the Department records showing: (i) The AEDM, including the mathematical model, the engineering or statistical analysis, and/or computer simulation or modeling that is the basis of the AEDM; (ii) Equipment information, complete test data, AEDM calculations, and the statistical comparisons from the units tested that were used to validate the AEDM pursuant to paragraph (f)(2) of this section; and (iii) Equipment information and AEDM calculations for each basic model to which the AEDM has been applied.

DOE may use the test data for a given individual model generated pursuant to §429.104 to verify the certified rating determined by an AEDM as long as the following process is followed: (i) Selection of units. DOE will obtain units for test from retail, where available. If units cannot be obtained from retail, DOE will request that a unit be provided by the manufacturer. (ii) Lab requirements. DOE will conduct testing at an independent, thirdparty testing facility of its choosing. In cases where no thirdparty laboratory is capable of testing the equipment, it may be tested at a manufacturer's facility upon DOE's request. (iii) Manufacturer participation. Testing will be performed without manufacturer representatives onsite. (iv) Testing. All verification testing will be conducted in accordance with the applicable DOE test procedure, as well as each of the following to the extent that they apply: (A) Any active test procedure waivers that have been granted for the basic model; (B) Any test procedure guidance that has been issued by DOE; (C) If during test setup or testing, the lab indicates to DOE that it needs additional information regarding a given basic model in order to test in accordance with the applicable DOE test procedure, DOE may organize a meeting between DOE, the manufacturer and the lab to provide such information. (D) At no time during the process may the lab communicate directly with the manufacturer without DOE present. (v) Failure to meet certified rating. If a model tests worse than its certified rating by an amount exceeding the tolerance prescribed in paragraph (f)(5)(vi) of this section, DOE will notify the manufacturer. DOE will provide the manufacturer with all documentation related to the test set up, test conditions, and test results for the unit. Within the timeframe allotted by DOE, the manufacturer may then present all claims regarding testing validity. (vi) Tolerances. for efficiency metrics, the result from a DOE verification test must be greater than or equal to the certified rating × (1 − the applicable tolerance).
(vii) Invalid rating. If, following discussions with the manufacturer and a retest where applicable, DOE determines that the testing was conducted appropriately in accordance with the DOE test procedure, the rating for the model will be considered invalid. Pursuant to 10 CFR 429.13(b), DOE may require a manufacturer to conduct additional testing as a remedial measure. [76 FR 12451, Mar. 7, 2011; 76 FR 24780, May 2, 2011, as amended at 78 FR 79595, Dec. 31, 2013; 79 FR 25505, May 5, 2014; 79 FR 27410, May 13, 2014] §429.71 Maintenance of records.(a) The manufacturer of any covered product or covered equipment shall establish, maintain, and retain the records of certification reports, of the underlying test data for all certification testing, and of any other testing conducted to satisfy the requirements of this part, part 430, and part 431. Any manufacturer who chooses to use an alternative method for determining energy efficiency or energy use in accordance with §429.70 must retain the records required by that section, any other records of any testing performed to support the use of the alternative method, and any certifications required by that section, on file for review by DOE for two years following the discontinuance of all models or combinations whose ratings were based on the alternative method. (b) Such records shall be organized and indexed in a fashion that makes them readily accessible for review by DOE upon request. (c) The records shall be retained by the manufacturer for a period of two years from the date that the manufacturer or third party submitter has notified DOE that the model has been discontinued in commerce. §429.72 Alternative methods for determining nonenergy ratings.(a) General. Where §429.14 through §429.54 authorize the use of an alternative method for determining a physical or operating characteristic other than the energy consumption or efficiency, such characteristics must be determined either by testing in accordance with the applicable test procedure and applying the specified sampling plan provisions established in those sections or as described in the appropriate productspecific paragraph below. In all cases, the computeraided design (CAD) models, measurements, and calculations used to determine the rating for the physical or operating characteristic shall be retained as part of the test records underlying the certification of the basic model in accordance with §429.71. (b) Testing. [Reserved] (c) Residential refrigerators, refrigeratorfreezers, and freezers. The total refrigerated volume of a basic model of refrigerator, refrigeratorfreezer, or freezer may be determined by performing a calculation of the volume based upon computeraided design (CAD) models of the basic model in lieu of physical measurements of a production unit of the basic model. Any value of total refrigerated volume of a basic model reported to DOE in a certification of compliance in accordance with §429.14(b)(2) must be calculated using the CADderived volume(s) and the applicable provisions in the test procedures in 10 CFR part 430 for measuring volume, and must be within two percent, or 0.5 cubic feet (0.2 cubic feet for compact products), whichever is greater, of the volume of a production unit of the basic model measured in accordance with the applicable test procedure in 10 CFR part 430.
