隨著節能減碳議題日益受到重視，建築產業的節能，特別是建築日常使用之節能與能源規範亦更加重要。欲達到有效的建築耗能控制，則需要一套能準確呈現出「建築節能熱點」的建築能源評估系統與指標，方能對症下藥，擬訂正確的節能減碳對策。

本研究首先著眼於過去台灣及國際間建築耗能統計與建築耗能指標之種種問題，包含：建築空間機能複雜且普遍混合使用；同類型建築營運時間不一、內部空間組成不一且設備量差異甚大；建築增改建、面積、使用機能改變；建築營業生意、來客率、出租率等變因不明等問題。這些問題使得過去以建築分類統計的EUI指標失去其準確性、代表性，而必須透過建築個案與耗能指標之間「營運條件一致化」與「空間組成一致化」兩大策略，方可修正上述不公平之處。

延續上述兩大策略，本研究發展出足以網羅台灣坊間建築空間類型的37種基本空間及其「標準營運條件」與「建築外殼性能與設備性能基準」，進而計算得此37種基本空間之EUI指標。接著，本研究根據此37種基本空間之面積比例與EUI指標，以面積加權平均的方式，組合成為無限多種建築EUI指標，完成了台灣建築動態EUI指標。

本研究接著利用四棟混用型建築，以可靠的建築能源模擬軟體eQUEST程式模擬建築耗能，再計算其動態EUI指標，並比較台灣過去建築EUI統計數值，最終確定了本動態EUI指標能反映建築空間變化造成的耗能變異，並能大致不差呈現出台灣各種建築耗能之概況。

本動態EUI指標之特色有二：其一，每一棟建築個案所面對的建築EUI指標皆根據其組成空間比例「量身訂做」而成，充分發揮「自己與自己比」的公平精神；其二，標準化建築營運條件，消除營運差異，使建築個案EUI值與其EUI指標之差，能完全呈現出建築個案節能設計之優劣。

Energy conservation codes for buildings are extremely crucial because people pay an unprecedented level of attention to energy conservation and carbon reduction. To control building energy use efficiently, a building energy evaluation system and an energy use intensity (EUI) index that can accurately identify the hot spot of the energy conservation of a building are necessary.

In this study, we initially focused on the problems encountered when building energy-use statistics and EUI indices have been used. These problems include contemporary buildings becoming increasingly complex and multipurpose compared with buildings constructed in the past; similar buildings are now composed of various space components, and operated with different schedules; and the rental rates and occupancies of similar buildings are indeterminate. Therefore, previous EUI indices have been inaccurate, unfair, and ineffective for determining the energy use characteristics of buildings that exhibit limitless space combinations. To modify such unfair situations, this study addressed that the EUI indices and every building's EUI should be compared under the same operation conditions and space components.

Subsequently, we collated 37 basic areas and their standard operation conditions, including operational hours, occupancies, lighting power requirements, and electric appliance power densities, according to the space components and energy-use features of commercial buildings in Taiwan and established the EUI indices of these areas. This study proposes a dynamic EUI index calculation that does not define the EUI index according to building type but separates a building into 37 basic areas at most, and then combines the EUI indices of these basic areas into a unique EUI index according to the area proportions.

Thereafter, this study used 4 normal buildings as examples, simulated their energy uses by using an energy simulation program, eQUEST, and calculated their dynamic EUI indices. The values of the dynamic EUI indices are almost close to the values of the simulated and statistical EUIs of the 4 buildings, respectively. Therefore, this study confirmed that the dynamic EUI index calculation method can be used for expressing the energy use variation of multiple building space components and is suitable for presenting the energy use conditions of buildings in Taiwan.
This dynamic EUI index calculation method is superior to previous EUI index because of 2 features: First, an EUI index is calculated for each building by using its own space components; thus, it is customized and comparable. Second, using standard operation conditions eliminates the energy use difference derived from operations, thereby enabling the EUI difference between a building and its EUI index to directly represent the benefits of the energy conservation design of a building.
