These procedures include measures of energyefficiency (e.g., annual fuel utilization efficiency (AFUE)), energy usedescriptors, annual fuel and electric energy consumption, andannual operating cost. And, by virtue of recent amendments, thetest procedure also includes provisions to measure and incorporateelectrical standby mode and off mode energy consumption.•Energy Conservation Standards:DOE set standards for these products in its recent Direct Final Rulepublished in theFederal Registeron June 27, 2011. This DirectFinal Rule sets minimum requirements for standby mode and offmode energy use in terms of measured wattages. (For example: 10watts for most furnaces and boilers effective May 1, 2013)Building Technologies Programeere.energy.gov8Regulatory History -continued– The Energy Independence and Security Act of 2007 (EISA 2007)Directs DOE to incorporate a measure of standby mode and offmode energy consumption into its test procedures.– EISA 2007 also directs DOE to integrate such energyconsumption into the energy efficiency, energy consumption, orother energy descriptor unless the Secretary determines thatcurrent test procedures already fully account and incorporate thestandby mode and off mode energy consumption or such anintegrated test procedure is technically infeasible.– In developing an amended test procedure, DOE must considerthe most current versions ofInternational ElectrotechnicalCommission (IEC) Standards 62301,“Household electricalappliances–Measurement of standby power,”and IEC Standard62087, “Methods of measurement for the power consumption ofaudio, video and related equipment.”Building Technologies Programeere.energy.gov9Review of EISA Amendments forFurnace and Boilers Test Procedures• DOE met its test procedure obligations under EISA 2007requirements forresidential furnaces and boilers through publication of a Final Rule onOctober 20, 2010. (75_FR 64621)– In completing this final rule, DOE determined that the test procedures requiredmeasurement and calculation provisions inorder to account for electrical standbymode and off mode energy use. Fossil-fuel standby mode and off mode energyuse was already integrated into the furnace and boiler test procedure.• For measurement of electrical standby mode and off mode wattages, DOE’samended test procedure utilizes IEC Standard 62301with clarifications. Akey clarification is that the existing test procedure specifications for ambienttemperature and voltage shall apply in lieu of IEC Standard 62301’sprovisions for these parameters.• It is noted that these amendments referenced thefirst editionof IECStandard 62301 for the electrical standby mode and off modemeasurements. Thefirst editionof IEC 62301was the most current versionof this industry standard at the time the final rule was issued.Building Technologies Programeere.energy.gov10Second Edition of IEC 62301• Since the time of the October 2010 final rule for furnaces andboilers, IEC has finalized a second edition to the 62301 standard.• DOE has reviewed the second edition of the IEC 62301and hasfound it to be superior to the first edition in a number of ways.(Details of this review are outlined in the following slides)• Consequently, DOE is proposing to incorporate IEC Standard 62301(Second Edition) in its entirety into the overall list of incorporatedreferences in DOE’s regulationsat 10 CFR 430.3 and to call out theapplicable provisions of that standard in DOE’s test procedureregulations for residential furnaces and boilers.Building Technologies Programeere.energy.gov11Details of DOE’s review of theSecond Edition IEC 62301 StandardDOE identified two areas of improvement:• Accuracy provisions, and• Specifications for stabilityBuilding Technologies Programeere.energy.gov12Details of DOE’s review of theSecond Edition IEC 62301 StandardAccuracy provision:• A more comprehensive specification of required accuracy isprovided in IEC Standard 62301 (Second Edition) that dependsupon the characteristics of the power being measured. DOEbelieves that this revision provides more realistic accuracyprovisions for a range of electricity consumption patterns, therebymaking the test method appropriate for the variety of electricityconsuming devices present in furnaces and boilers.• The new specification can be met by commercially-available testequipment, whereas requirements in the first version may haverequired specialized instrumentation that is not readily available.Building Technologies Programeere.energy.gov13Details of DOE’s review of theSecond Edition IEC 62301 StandardACCURACY PROVISION:• Explaining further, the second edition specifies instrument accuracybased on the expected uncertainty. The uncertainty depends upon avalue termed the Maximum Current Ratio (MCR), which is the ratioof the Crest Factor to the Power Factor of the signal. e.g.Forsignals with MCR’s less than 10, the allowed instrument uncertaintywould be 2 % at the 95 % confidence interval for power valuesgreater than 1.0 W. For measured power values less than 1.0 W,the maximum permitted absolute uncertainty would be less than orequal to 0.02 W at the 95 % confidence interval.• DOE believes both levels of uncertainty are sufficient to assess thestandby mode and off mode energy consumption of furnaces andboilers.Building Technologies Programeere.energy.gov14Details ofDOEreview ofSecondEdition IEC 62301 Standard(continued)Stability:• IEC Standard 62301 (Second Edition) contains more detailedtechniques to evaluate the stabilityof the power consumption and tomeasure the power consumption for loads with different stabilitycharacteristics. A longer observation period is prescribed in thesecond edition. For constant power modes, the test methodspecified in the second edition matches that specified in the firstedition. These techniques will result in more accurate measures ofstandby energy consumption over a variety of operationalcharacteristics that could be associated with the electricalcomponents of furnaces and boilers.• The user is given a choice ofmeasurement procedures, includingless burdensome methods such as direct meter reading methods ifcertain clearly-described stability conditions are met.Building Technologies Programeere.energy.gov15Details ofDOEreview ofSecondEdition IEC 62301 Standard(continued)Summary:• DOE believes that the changes incorporated in IEC Standard62301 (Second Edition) would allow for use of lessburdensome methods when appropriate and would ensureaccurate measures of standby energy consumption over arange of operating conditions that may be observed inresidential furnaces and boilers.• In addition,DOE has examined some common commerciallyavailable instrumentation for making these measurements,and DOE has determined that the specifications in the secondedition are more in line with the performance specifications ofcommercially-available equipment.Building Technologies Programeere.energy.gov16Closing Remarks and CommentsAt this time, DOE welcomes any additional remarks orquestions from interested parties on the NOPR includingthe following:–Use of the IEC Standard 62301–Any other issues or concernsBuilding Technologies Programeere.energy.gov17How to Submit Written Comments•In all correspondence related to this rulemaking, please identify theResidential Furnaces and Boilers Test Procedure Rulemaking byproviding the following information :– Residential Furnaces and Boilers Test Procedure Rulemaking,– Docket Number EERE–2011–BT–TP–0007, and– Regulatory Identification Number (RIN) 1904-AC44•Email:FurnaceBoiler‐IEC‐2011‐TP@ee.doe.gov•Comment period closes: November 28, 2011Postal:Courier:Ms. Brenda EdwardsU.S. Department of EnergyBuilding Technologies Program, Mailstop EE-2J1000 Independence Avenue, SWWashington, DC 20585-0121Ms. Brenda EdwardsU.S. Department of EnergyBuilding Technologies Program, 6th Floor950 L’Enfant Plaza, SWWashington, DC 20024Tel: 202 586-2945
