一、研究緣起
我立法院於2015年通過「溫室氣體減量及管理法」，宣示全國溫室氣體排放量在2020、2050年之前分別要降低2005年之20、50%水準。在此壓力之下，內政部被要求必須分攤住商部門之減碳目標，亦即要求達成(1)新建建築之建築外殼設計基準值，2020年較2016年提高10%， (2)公部門建築用電效率2020年較2016年改善5%，2025年改善10%，且達到公告之耗能密度指標(Energy Usage Intensity EUI)規範之目標。
二、研究方法及過程
本研究設定以節能敏感度最高的空調節能為焦點，採用現行綠建築標章之空調系統節能係數EAC(空調系統節能係數EAC根據期末評審意見，由綠建築評估手冊空調系統節能效率EAC更名而成)作為建築技術規則的新強制型節能管制策略。本研究將透過eQuest的建築耗能軟體來執行既有外殼節能指標體系與本EAC指標空調節能體系的空調節能效益分析，以彰顯本空調節能法規的節能效益。
三、重要發現
本計畫提出在建築技術規則增修空調節能設計管制的條文與技術規範，同時也將提出該法案在建照審查與第三方認證的方法如下:
1.研擬建築空調節能管理法規條文
2.研擬EAC指標計算技術規範
3.研擬EAC指標行政審查建議方案
四、主要建議意見
建議一
建議續進行「非住宅類建築物能源計算標準與標示法」相關研究，以作為未來綠建築標章中規劃納入包含EAC指標之能源標示制度參考與依據:立即可行建議
主辦機關: 內政部建築研究所
協辦機關: 財團法人台灣建築中心
建議內容:
本研究雖建議將EAC納入「新建建築物節約能源設計標準」，但由於行政作業與統合業界意見尚需時日，短期內更有效方法為先由綠建築標章中執行以EAC變數作為建築能源標示的方法。本研究建議可續進行「非住宅類建築物能源計算標準與標示法」相關研究，以作為未來綠建築標章納入包含EAC指標之能源標示制度同步執行依據，並供日後以自願方式執行EAC管制之策略，同時可導入能源標示制度以有效落實管制住商能源節約之政策。
建議二
建議進行「新建建築物節約能源設計標準」條文增修，納入中央空調系統（EAC指標）設計基準，與修訂「建築物空氣調節設備專業工程部分專業技師辦理簽證項目」，以利落實建築空調設備系統節能與管制:中長期建議
主辦機關: 內政部營建署
協辦機關: 內政部建築研究所、經濟部能源局、空調技師公會
建議內容:
本研究已完成新建建築物中央空調系統（EAC指標）設計基準，建議會同相關單位於「新建建築物節約能源設計標準」中增修 EAC 指標條文，相關(草案)增修訂條文對照表如本研究報告第 4 章第1 節所示。同時建議修訂內政部 85 年 6 月 22 日（85）內營字第八五Ｏ三九Ｏ六號函公告之「建築物空氣調節設備專業工程部分專業技師辦理簽證項目」，納入建築空調設備系統節約能源 EAC設計內容，以利落實建築空調設備系統節能與管制。

Research Background:
In 2015, the Legislature Yuan passed the Greenhouse Gas Reduction and Management Act which declared that Taiwan’s Greenhouse Gas reduction level in 2020 and 2050 will reach the goal of 20 and 50% of 2005’s Greenhouse Gas emission level. With the targets stipulated, Ministry of the Interior was requested to tackle both residential and commercial sectors in order to share the carbon reduction goal namely (1) The energy conservation index of new building envelope design should be increased by 10% in 2020 compared to existing regulations and (2) The energy efficiency of governmental buildings should be improved by 5% in 2020 and 10% in 2025 compared to power usage levels recorded in 2016 and lastly, achieving the announced target level
of Energy Usage Intensity (EUI) Standard.
Research Methodology:
Our research team focuses on AC energy conservation as it is highly sensitive to various kinds of energy saving solutions. This research will apply the existing energy efficiency index of EAC from the Green Building Design Manual as a new mandatory energy efficiency control strategy for the Building Technical Regulation. Also, this research will introduce eQuest software to simulate the energy conservation effects between the existing building envelope oriented system and the AC energy management system of EAC index so as to highlight the energy saving effect of this AC energy conservation regulation.
Major Outcomes:
This research will propose a new regulation and technical code of the AC efficiency design control for the Building Technical Regulation and will also propose the method for carrying out building license review and third party
certifications under this regulation as suggested below:
1.Establish Building AC Energy Conservation Management Regulation
2.Establish EAC Index Calculation Technical Regulation
3.Establish EAC Index Administrative Review Proposal Plan
Main Recommendations:
Recommendation 1:
Continuation of「Energy Calculation Standards and Labeling Method for Non-Residential Buildings」Research for future Green Building Labeling System enhancements such as incorporating EAC Index and Energy Labeling Code
Feasibility: Highly Viable
Main Organizer: Architecture and Building Research Institute
Co-Organizer: Taiwan Architecture & Building Center
Although this research recommends incorporating EAC into「Energy Conservation Design Standards for New Building Construction」, due to the limited time needed to integrate inputs from various administrations and professional bodies, a more efficient and quicker method is to utilize EAC variables to conduct Building Energy Labeling as part of the Green Building Labeling System. It is recommended that「Energy Calculation Standards and Labeling Method for Non-Residential Buildings」could be conducted in line with Green Building Labeling System in order to synchronize with future EAC control strategies as well as incorporating the above systems into the Energy Labeling Code to establish effective Residential and Commercial Energy
Conservation policies.
Recommendation 2:
Execution of「Energy Conservation Design Standards for New Building Construction」Amendments, Incorporation of Central Air-Conditioning System (EAC Index) Design Standard and「Building Air-Conditioning Equipment and Professional Air-Conditioning Visa Certifications」Amendments to establish Energy Conservation
and Regulation for Building Air-Conditioning Equipment Systems
Feasibility: Medium and Long-Term Goals
Main Organizer: Construction and Planning Agency
Co-Organizer: Architecture and Building Research Institute , Energy Bureau/ Ministry of Economic Affairs, Air-Conditioning Technician Association
This research has completed the design benchmark for the Central Air-Conditioning System (EAC) in New Building Constructions. It is recommended together with the Energy Bureau that the EAC Index provisions to be revised and incorporated into the「Energy Conservation Design Standards for New Building Construction」as shown in Chapter 4, Section 1 of this research report. It is also recommended to revise Code No. 8503906「Building Air-Conditioning Equipment and Professional Air-Conditioning Visa Certifications」as announced by the Ministry of the Interior on the 22th June 1996 to be incorporated into the Energy Conservation EAC
Design to facilitate the implementation of Energy Saving and Regulation of Building Air-Conditioning Equipment Systems.
