Energy Situation in Taiwan

More than 99% of energy was imported. In 2008, the final energy consumption for Industry sector is 52%, Residential

and Commercial sectors 24%; Transportation sector 13%. In 2008, the electricity consumption for Industry sector is 49%, Residential and

Commercial sector 37%.

Background

• The Chiller Energy Efficiency Standard has beenenforced in 2003 and upgraded in Jan.1, 2005

• To effectively implement the control mechanism,Bureau of Energy of MOEA ask EEL of ITRI assistanceto promote and implement the control mechanism .

• To comply with the government energy conservationgoal, and provide assistance to domestic chiller makersto up-grade their technologies, EEL further authorizedTaiwan Refrigerating and Air-Conditioning EngineeringAssociation (TRACEA) to promote and implement thecontrol mechanism under voluntary base from 2003.

• Introduction





Guideline for Implementation

• Accreditation to manufacturer’s testing facility,Authorization to their own testing report, and Assessmentafter receiving the testing report. (3A)

• Review the manufacturers test laboratory for their QA system,test methods and procedure, test personnel qualification,operation procedure, instruments calibration records.

• Authorize manufactures to test their chiller energy efficiencyby themselves.

• Submit the test report to TRACEA for control, themanufactures may label their chillers with certified tag anddeliver to it’s the clients.

• An experts team formed by TRACEA may draw the productsand send to a TAF (Taiwan Accreditation Foundation)certified laboratory for re-testing in random base.

Implementation Procedure

• Organizing the chiller energy efficiency control experts team.• Chiller manufactures apply to inspect and certify their test station.• Arrange the expert team for test station visiting and inspectation,

it will be a one day visit, include documents review & approval,shop inspect and chiller test witness.

• After the visit and review, the expert team will write the visitreport and comments; and decide if they need for second visit.Final review shall be either documents review or shop review.

• Expert team held meeting to approve test report.• Authorize the manufactures toy test theirs chiller energy

efficiency by themselves, then submit the test report to TRACEAfor control, the manufactures are award a certification to identifytheir qualification, the manufactures can label their testedproducts with certified tag and deliver to it’s the clients .


Implementation Procedure(cont.)

• The products with certified tag means its energyefficiency meets the national standard and allowto sell. The TRACEA may periodically publishthe testing result.

• Afterward audit and random inspection：

1. Random draw inspection;

2. By application (Users or Hostile competitors)

• Random inspection may send to TAF certifiedlaboratory for test and comparison.

Current Status of Voluntary Mechanism

• 23 testing facilities in 13 local manufacturers havebeen awarded the certification. 15 testing facilities for5 foreign manufacturers were also passed theassessment and got the certification.

• These manufacturers can test their own chiller unitsand submit the testing reports to TRACEA for theirreview and got the passing stick to put on their chillerunits.

• There are more than 2000 units has been awarded thelabeling sticks by the end of last year (2009).


• Introduction





Shifting from Voluntary to Mandatory

• The revised Energy Management Law wasreleased in June of 2009.

• ITRI has set up the testing facilities with testingcapacity 2000 RT for water-cooled and 200 RTfor air-cooled units.

• It means that we have set up the enoughcapability to test most of the local or importedchiller units.


Proposal for Mandatory Mechanism

• Similar procedures as the voluntary mechanism(3A)– Accreditation to manufacturer’s testing facility

– Authorization to their own testing report

– Assessment after receiving the testing report

• Multi-level of energy efficiency

• Standard type – post on the website in advance.

• Non-standard type – post on the website afterget the testing report


Proposed Schedule

2012~201120102003~2009

Adjustment Period MandatoryVoluntary

Encourage the up loading ofthe testing report

Mandatory up loading of testing reportand meet the efficiency requirement

Draw the mandatory regulation and publish

Random inspection for each manufacturers

Mandatory report forall the units

Set up multi-level of energyefficiency standards

Publish thestandards

Enforcement formulti-level labeling

Set up and draw theIPLV standards

Enforcement forIPLV standards


• Introduction





Conclusion Remarks

• The enforcement of the mandatory mechanism is oneof the strategies to meet the target for energyconservation. It also can upgrade the technology forlocal manufacturers and increase the capability ofglobal competition.

• Gradually shifting from voluntary to mandatory canreduce the impact for local manufacturers.

• Multi-level and IPLV are still under reviewingprocess. We will come out a suggestion forgovernment reference before the enforcement ofmandatory mechanism.
