近年來，節能減碳的思潮帶動了建築能源評估管理政策蓬勃發展，世界各國皆企圖以此控制建築產業之能源消耗，台灣亦然。檢討台灣的建築節能法規發現，其對於建築物僅採單一耗能基準規範，無法反映建築內部空間組成比例、能源使用強度等差異；這樣的建築能源評估方式面對內部空間組成複雜且各空間能源使用差異極大的醫院建築時，將造成評估上較大的差誤與不公平之現象。
因此，本研究針對台灣中部地區各級醫院建築5間樣本，調查各醫院建築內部10種主要空間之照明及設備耗能數據，並配合動態能源解析軟體「eQUEST」模擬各空間之空調耗能，以分析醫院各空間之耗能特性；最終本研究發現，醫院的耗能多寡與醫院之等級應無直接關係，而與醫院內部空間組成比例有關；本研究並歸納醫院內部空間的耗能特性，提出醫院建築實行能源評估時之5大類耗能分區建議：
1. 12小時低耗能區：含門診區
2. 12小時高耗能區：含復健部、藥劑部、放射部、血液透析中心及檢驗部
3. 24小時低耗能區：含一般病房區
4. 24小時高耗能區：含急診區及加護病房
5. 24小時開刀房區：含開刀房
12小時低耗能區及24小時低耗能區總耗電強度落在250~260 kWh/ (m2‧yr) 附近；12小時高耗能區與24小時高耗能區總耗電強度則落在550 kWh/(m2‧yr)附近；24小時開刀房區總耗電強度約為700 kWh/(m2‧yr)，為醫院建築中最耗能的區域。

In recent years, the ideological trend of energy conservation and carbon reduction has driven the development of building energy assessment. More and more countries around the world and also Taiwan are attempting to control the energy consumption of construction industry based on this reason.
From the policy of building energy conservation it was found that it only utilizes single type of energy consumption standard regulation regarding to the buildings so it could not reflect the difference of the proportion of their internal space composition and Energy Usage Intensity (EUI). This kind of building energy assessment will cause some mistakes and unfairness during assessment confront with hospital buildings which contain complicate composition of the internal spaces and also huge difference in energy usage of each space.
Regarding to this situation, this study focused on five hospital buildings of each rating in central part of Taiwan, investigating lighting and equipment energy consumption data from ten types of main space in the building, also coordinate with computer software, eQUEST to simulate the energy consumption of AC in each space for analyzing usage.
In our final studies we found that the energy consumption of hospital is not directly related to the rating, but related to the proportion about the composition of internal space in hospital. Our study has generalized the features of energy consumption for internal spaces in hospital and also proposed suggestions for the hospital building to implement five types of energy consumed partition during energy assessment.
1. 12hours low energy consumed area: outpatient department
2. 12hours high energy consumed area: Physiotherapy, Pharmacy, department of Radiology, Hemodialysis center and Health screening centre
3. 24hours low energy consumed area: general ward area
4. 24hours high energy consumed area: emergency ward area and Intensive Care Unit (ICU)
5. 24hours operating room area: operating room
Total EUI of 12hours and 24hours low energy consumed area falls in the range of 250~260 kWh/ (m2‧yr) while total EUI of 24hours operating room area is around 700 kWh/(m2‧yr) which is the most energy consumed area in the hospital building.
