鑑於全球持續暖化所造成的影響，國際間除了聯合國氣候變化綱要公約(United Nations Framework Convention on Climate Change, UNFCCC)下簽署的京都議定書(Kyoto Protocol)外，歐盟亦提出各項因應措施，2002年所通過的建築能源效率指令 (Energy Performance of Building Directive, EPBD 2002/91/EC) 為建築節能最主要的強制性法律文件，強制規定各成員國需執行建築物能源效率認證 (Energy Performance Certification，EPC)，歐盟各國在建物節能技術也已發展多年。國際能源總署於2008年報告提出關於建築節能、提升能源效率策略中，執行強制性建築能源證書政策具顯著成效。
台灣建築使用型態相較於歐美國家具複合性及多樣化，為落實執行並擴大建立建築整體能源耗用管理機制，我國內政部建築研究所於2019年完成既有建築綠建築評估手冊(EEWH-EB)，並於2020年研擬建築能效評估手冊，建立台灣建築能效評估制度TBERS (Taiwan Building Energy-Efficiency Rating System)，為以建築整體能源耗用為評估方向的建築能效評估制度。推動建築能效評估制度需從法令政策、查驗標準、權責機構、獎勵措施等方面分階段逐步執行，而開發建築能效評估軟體並推動使用對於發展建築能效評估制度具有良好之效益。
本研究承襲內政部建築研究所研擬之既有建築綠建築評估手冊及建築能效評估手冊，於此架構下開發適用於我國之建築能效評估試算軟體，利用普及性高的Excel作為軟體工具，並透過實際案例試算檢視建築能效評估方法在實務操作上之可行性。開發之建築能效評估試算軟體為有良好使用者體驗，介面設計參考使用者介面設計要點，並經過軟體實測與問卷調查蒐集受測者回饋與建議，逐步修改優化軟體設計。
本研究開發之建築能效評估試算軟體經測試後具有良好使用者介面設計及運算準確性，未來可作為建築能效正式評估工具，亦可參照國外案例，開放供民眾試算使用，增加人民對於建築節能意識，提高改善建築能耗意願，協助推動台灣建築能源能效評估制度。

According to the report of the International Energy Agency in 2008, the implementation of the mandatory building energy certificate policy has achieved remarkable results in the strategy of building energy conservation and improving energy efficiency. However, the building type and usage in Taiwan is more complex and diverse than in Europe or USA. The Architecture and Building Research Institute, Ministry of the Interior developed the Building Energy evaluation manual in 2020, and established Taiwan Building Energy-Efficiency Rating System which is the first energy efficiency evaluation method in Taiwan.
This research is based on Taiwan Building Energy-Efficiency Rating System, and the purpose of this study is to develop the building energy efficiency calculation software by using Excel as the tool. There were four software established totally. The main target users in the future are authorized experts and citizens. Good user interface design can improve the users' operation efficiency and flexibility. Therefore, the interface design referred to the 10 Usability Heuristics for User Interface Design composed by Jakob Nielsen in 1994 for better user experience. The software was tested few times by testers who have related background, such as architecture, electrical, mechanical, and so on. After testing, testers’ feedback and suggestion were collected via questionnaire, and the software design was modified and optimized gradually.
The result of building energy calculation software which can be used as formal evaluation tools in the future has good user experience and accuracy. The tool can also be released to public, which can increase the awareness of energy consumption and efficiency, and raise the willingness to optimize existing buildings. Furthermore, it can assist to execute the Taiwan Building Energy-Efficiency Rating policy in the future.
