一、研究緣起
2015年《巴黎氣候協定》與2021年COP26會議，呼籲世界各國在2030年宣示或達成，最慢也應在2050年全面達到淨零排放的目標，我政府已要求各部會訂立淨零排放期程及行動方案，其中淨零建築(Net Zero Building)為賦予內政部的任務。為此，ABRI決定在我綠建築標章制度內導入歐盟建築能效指令EPBD之建築能效評估及標示制度系統，以作為邁向淨零建築的策略。
二、研究方法及過程
繼ABRI109年”住宅綠建築能源計算基準與標示之研究”案之成果，本計畫希望進一步結合現有綠建築標章制度，建立一套以現有EEWH-RS之EEV、EAC、EL、固定設備等節能指標的住宅能效評估方法。此方法是以既有綠建築標章整合住宅能效標示制度的新制度，如此可讓住宅政策在現有成功的綠建築制度下提升建築節能成效。由於在台灣集合住宅佔有總用電約30~ 35%的高用電比，因此本計畫必須開發一個足以預測集合住宅公共用電，並結合住宅單元的固定設備耗能之新建築能效評估法，並且能發展成EEWH-RS手冊的日常節能RS得分計算法。
三、重要發現
本研究對於透天住宅採用建築外殼、空調、照明、熱水器、爐台五項能效指標來評估，對於非透天集合住宅除了前述五項指標之外，還加上電梯、揚水泵、地下室送排風機等三項公用機械之能效指標做為住宅能效評估法R-BERS之依據。R-BERS採用七等級的建築能效標示，同時以標示額外1+等級的近零碳建築NZCB (Nearly Zero-Carbon Building)作為近零碳建築政策之「建築最高能效」標示，以宣示能與聯合國的淨零排放與內政部的淨零建築政策。1+等級被設定為減碳率30%作為近零碳建築之目標，藉以呼應「溫室氣體減量及管理法」對內政部於2025年前發展建築能源護照之要求，同時也是落實我國淨零建築政策的第一步。
四、主要建議意見
建議一:
將本研究完成之EEWH-RS手冊公告徵求意見，並經修正後擇期正式公告實施:立即可行性建議
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
建議二:
將本研究R-BERS關於集合住宅能效評估之重點，回饋給國家住宅及都市更新中心以修正相關社會住宅發包相關規範:立即可行性建議
主辦機關:財團法人台灣建築中心
協辦機關:內政部建築研究所、國家住宅及都市更新中心
本研究R-BERS乃是為了我國社會住宅執行淨零排放政策之目的而研擬的建築能效評估法，其中尤其是固定設備與公用機械設備之能效設計方法對社會住宅的節能減碳有明確的效益，應將本研究成果具體融入相關社會住宅發包相關規範。
建議三:
辦理EEWH-RS與R-BERS課程講習訓練:立即可行性建議
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
建議四:

1.Background
Paris Agreement 2015 and COP26 2021 have being appeal the whole word’s countries to commit or to meet by 2030, or at least to reach the Net Zero Emission goal by 2050. Under such circumstance, the Taiwan government has asked her Ministries to establish the schedule and the action plan of their own Net Zero policy, and the Net Zero Building policy is requested for the Ministry of the Interior. For this purpose, ABRI is going to introduce the EPBD’ building energy rating system into the existing Green Building system to achieve the Net Zero Building policy.
2.Method and proceses
Based on the result of ABRI’s 2020 project of “Promotion Project for integrating the EEWH-RS Green Buillding System with Building Energy Rating System”, this project is supposed to establish a building energy efficient rating method using the existing energy indexes of EEV、EAC、EL and fixed equipments in EEWH-RS system for residential buildings. This method is a new system integrated the existing Green Building Label system with the Building Energy-Efficient Rating System that can promote the energy conservation effect of Residential Building Policy under the existing successful Green Buillding System. Because the public electric consuptuion share a very high of 30~35%, this project have to develop a new integration rating system to predicte the public electricity and the energy efficient of housing units so as to develop a new evaluation method of RS point method in the Daily Energy Index of EEWH-RS.
3.Important finding
This project develop the Residential Builing Energy Efficiency System R-BERS which applied 5 indexes of building envelope, AC, lighting, water heater, cooking stove in the enery efficiencies evaluation for house buildings, and introduced 3 indexes of elevator, water pump, exhaust fan besided the aboved 5 indexes in the enery efficiencies evaluation for codominium. There are 7 energy levels were applied in R-BERS and a extra NZCB (Nearly Zero-Carbon Building) presented by 1+ level was introduced to present top energy efficiency of Nearly Zero Carbon Building so as to appeal the Net Zero Emission policy of UN and the Net Zero Building policy of the Ministry of the Interior. NZCB level 1+ was set on the goal of 30% carbon reduction rate to response the request of developing a Building Energy Passport system by 2025 from ” Greenhouse Gas Reduction and Management Act’ and be the first step of Net Zero Building policy in Taiwan.
