建築能效標示制度認知與政策工具運用關聯性分析

Cognition Analysis of Building Energy Efficiency Labeling System and the Application of Policy Instrument

2021年住商部門佔總排碳量，全國約占21.9%，台北市約佔75.88%。各國皆認為建築能源效率會是住商部門能否達到淨零排放的重要指標，無不積極推動建築能效標示；不過能效標示必須搭配自願性或強制性的政策工具才會發生效果。文獻回顧發現標示制度成功與否取決於標示「感知」、「品質」及「信任」三面向的發展程度。本研究歸納3面向的8個認知構面及其16項評估項目與7項政策工具，經問卷抽樣調查分析，發現「信任」面向之6項重要評估項目最受重視，其中以「評估人員條件」、「培訓認可條件」及「抽複查機制」3項評估項目對標示公信力影響最大。至於「感知」面向則僅有「與建築節能相關職業」(即資訊提供族群)的認知程度較高，未與建築節能議題接觸者，感知普遍不足，與從事建築職業無關。另外，彙整出7項政策工具之評估項目相關性分析表，自願性政策工具明顯較強制性政策工具受青睞；「強制性」的政策工具著重於「標示機構公正性」與「評估人員專業性」，不論是資訊提供或接收者，認知一致，為該政策工具之重點施政作為。「經濟手段」的政策工具，並無偏重那個面向，應從各面向並進，惟職業別與居住地區別特徵認知差異大，應針對不同族群調整施政作法，「資訊透明化」之政策工具，著重於機構公正性、辦理程序嚴謹性，應防止制度容易發生弊端的問題，並彙整出政策工具與評估項目之相關性分析表，供後續推動政策工具的參考。

 

In terms of the total carbon emissions accounted for by the residential and commercial sector in 2021, it accounts for approximately 21.9% nationwide and 75.88% in Taipei City. Various countries believe that building energy efficiency will be an important indicator of whether the residential and commercial sectors can achieve net-zero emissions, so they all actively promote building energy efficiency labels; however, energy efficiency labels must be paired with voluntary or mandatory policies to be effective. A review of the literature found that the success of a labeling system usually depends on the degree to which the public has developed three aspects of labeling: "perception", "quality" and "trust". This study summarized the 8 cognitive aspects of the 3 aspects and their 16 evaluation items and 7 policy Instruments. After a questionnaire survey and analysis, it was found that the 6 important evaluation items of the "trust" aspect received the most attention, among which the "evaluator" was the most important. The three evaluation items, "Conditions", "Training Accreditation Conditions" and "Spot Review Mechanism" have the greatest impact on the credibility of the label. As for the "perception" aspect, only "occupations related to building energy conservation" (that is, the information providing group) have a higher level of awareness. Those who have not been exposed to building energy conservation issues generally have insufficient awareness, which has nothing to do with being engaged in the construction profession. In addition, a correlation analysis table of the evaluation items of 7 policy Instruments was compiled. Voluntary policy Instruments are obviously more popular than mandatory policy Instruments; "mandatory" policy Instruments focus on "marking the impartiality of the organization" and "professionalism of the assessor". "Sex", whether the information provider or the receiver has a consistent understanding, is the key governance action of this policy Instrument. The policy Instrument of "economic means" does not focus on one aspect. It should be based on all aspects. However, there are great differences in the recognition of the distinguishing characteristics of occupational gender and place of residence. Governance practices should be adjusted according to different ethnic groups. The policy Instrument of "information transparency" focuses on Regarding the fairness of the institution and the rigor of the processing procedures, we should prevent problems that are prone to malpractice in the system, and compile a correlation analysis table of policy Instruments and assessment items for reference in the subsequent promotion of policy Instruments.
