ㄧ、計畫緣起
因應「台灣2050淨零路徑」，內政部建築研究所(以下簡稱ABRI)已於2022年提出建築能效評估系統BERS作為淨零建築政策的檢驗工具。然而，原BERS僅能適用於部分建築類型的能效評估，可能無法達成「2050台灣淨零路徑」要求所有新建建築物與85%的既有建築在2050年應達成BERS認證的近零碳建築等級之政策任務。為了克服此困境，本計畫建置了幾乎可適用所有建築類型的新BERS系統，該新系統包含非住宅與住宅兩大系統，其中非住宅建築專用的大系統還內含新建建築專用的BERSn以及既有建築專用的BERSe、E-BERSe、BERSc三類一共有四個次系統，另外住宅專用的大系統中內含新建住宅專用的R-BERSn、RP-BERSn二類以及既有住宅專用的R-BERSe、RP-BERSe二類一共有四個次系統(全部內含八次系統)。
二、執行方法及過程
本計畫已完成幾乎可適用所有建築類型的新BERS手冊，同時創造了一個嶄新的「簡化全棟EUI理論」來取代來適用於非住宅建築能效評估中精密但作業繁複的「動態EUI理論」。改用「簡化全棟EUI理論」之後的新BERSn與新BERSe可縮減70%BERS評估的計算量與作業時間，對淨零建築政策有莫大貢獻。
本計畫另外發展的既有建築專家能效診斷評估系統E-BERSe，是因應複雜化、多樣化、混合使用的龐大既有建築市場所開發的快速現場診斷評估法。E-BERSe必須委由合格開業的空調技師或建築師之專家來執行，只要由一位專家現場診斷完成EAC、EL指標後立即能有效執行完成一份既有建築的BERS評估工作。由培訓空調專業專家所支援的E-BERSe，不只是一個具有高度信賴性的現場評估系統，同時也是淨零建築政策執行既有建築能效評估與能效改造的有效工具。
本計畫新發展的既有住戶家庭的R-BERSe，是以台電2022年全國家庭用電密度EUI統計分布為基礎，可採用住戶電費單據來執行單一住宅的能效評估方法。另外發展的RP-BERSn是因應無固定設備的毛胚交屋集合住宅案件，僅針對公共空間之三項主要機械設備執行能效評估。另一新發展的RP-BERSe則提供集合住宅能效更新診斷之用。由於顧及民眾隱私權、難取得必要設備資料以進行正確能效評估，RP-BERSe只提供一份建築能效診斷檢核表供大樓管理員來檢視幾項共用設備的能效，不接受官方的認證申請。最後，本計畫同時將提出具有民眾參與以及建築能效線上計算服務的「住宅建築能效評估服務平台」，未來將納入ABRI之正式網站，可彰顯淨零政策之成效。
三、重要發現
本計畫被要求一個適用所有建築物的建築能效評估系統是不可能的任務，因為目前其他國家均無法創造一個如此全方位的評估系統，但本計畫最後終於在「台灣2050淨零路徑」的目標下完成了此不可能任務，期待能藉此呼應所有新建建築物與85%的既有建築在2050年應達成BERS認證的近零碳建築等級之要求（國家發展委員會等，2022）。
四、主要建議事項
本計畫已完成幾乎可適用所有建築類型的新BERS手冊，應可依行政程序提送專家評審、公開閱覽後擇期正式公告實施，並可依新BERS手冊針對綠建築機構的評定助理、審查專家展開再訓練，同時可修改EEWH-BC、EEWH-RS、EEWH-EB、EEWH-RN等牽涉BERS評估的綠建築評估手冊以期能使綠建築標章與建築能效評估制度無縫接軌。

1.Background
In order to response the “Taiwan 2050 Net Zero Roadmap”, ABRI have proposed a Building Energy-Efficiency Rating System BERS as the inspect tool of the Net Zero Building Policy. However, the proposed original BERS was adaptable only for several building catagories so that could not meet the policy mission of “Taiwan 2050 Net Zero Roadmap” which requests all new buildings and 85% of existing buildings should get the Nearly Zero Carbon level certification by 2050. To overcome this abtacles, this project developed a new BERS which can adaptable to almost all building catagories including two main systems of residential building and nonresidential building. The main systems of nonresidential building contains a subsystem BERSn for new buildings and 3 subsystems, BERSe、E-BERSe and BERSc, for existing buildings, totally 8 subsystems.
2.Method and Process
This project developed a new BERS which can adaptable to almost all building catagories and created a big innovation to propose a new simplified Whole Building EUI theory to subtitute the sophisticate and complicated caculation method of Dynamic EUI theory used in the existing BERS rating of nonresidential building. Using the simplified Whole Building EUI theory, the new BERSn and new BERSe could save 70% of calculation and operation times of BERS rating that is a big contribution to the Zero Building Policy.
This project proposed an Expert Building Energy-efficiency Dianostic Rating System E-BERSe which is a quickly onsite dianostic rating method to meet the huge requirement of existing sophisticated, divesed and mixused building market. Because E-BERSe can only be excuted by  qualified experts trained by the BERS rating institute, a BERS rating job can be completed very efficiently just when the EAC、EL indexes can be diagnosed onsite by a qualified expert. E-BERSe supported by well trained AC professional experts is not only a high reliable onsite rating system but also an efficient tool for the energy-efficiency rating and energy-efficiency innovation of existing building in the Net Zero Building Policy.
This project also developed a new R-BERSe for existing households which can evaluate the energy-efficiency of a household unit using its electricity bill based on a national average EUI distribuition statstics done by Taiwan power 2022. Another developed RP-BERSn is designed to evaluate only the energy-efficiency of 3 main public mechanical equipments for the rough unequipped condominium housing without fix equipments. Another developed RP-BERSe is proposed for the energy-efficiency innovation dianosis of existing condominium housing. RP-BERSe can only give a chech list and let the building manager to diagnos the energy-efficiency of some public equipments and do not accept any official certification application because it involve personal privacy and difficault to get the necessary equipment information to do a correct rating.  Finally, this project proposed a “Residential Building Energy-efficiency Rating Service Platform”, with public partipation and online service function, which will be combined into the total Net Zero Building Service Platform in thefuture so as to demonstrate the astonishing achievement of Net Zero Policy.
3.finding
This project is asked to propose a new BERS which can adaptable to all building catagories that is an impossible mission because no other countries could create such an omnidirectional rating system today. However, this impossible mission was finally finished under the “Taiwan 2050 Net Zero Roadmap” policy and is expected to response the request that all new buildings and 85% of existing buildings should get the Nearly Zero Carbon level certification by 2050.
4.Suggestions
This project have already proposed a new BERS manual so that the necessary processes such as expert inspection, public reviewing, public announcement, can be excuted by the govemental tempo. By this new BERS, the retraining course for certification affair assistants and review professionals of Green Building Certication Institute should be promoted, and the existing Green Building Manuals, EEWH-BC、EEWH-RS、EEWH-EB、EEWH-RN, connecting with the BERS rating shoud be renewed so as to integrate semlessly the Green Building Policy and the Building Energy-Efficiency Rating Policy.
