碩士 === 國立成功大學 === 建築學系碩博士班 === 97 === This study analyzed the data from references to find out the energy consumption condition of buildings in Taiwan. It proposed seven factors for EUI classification according to the consumption types of buildings and the demand for energy management. The factors ranked by the importance of the effect on EUI were showed as follows: (1) function of building, (2) building type, (3) requirement amount of facilities, (4) working hour, (5) air-condition type, (6) operating style, (7) EUI value. The classification made out of the seven factors should fit the usage of every day energy consumption management, at the same time, it will be used as basis to find out energy consumption type of every type of building. According to the seven factors, this study sets up a category for building function: (1) office, (2) recreation and culture, (3) hospital/ public welfare/ regeneration, (4) business, (5) housing. And this study selected 26 function types of business building to investigate for data. Because the insufficient original data of 30 categories, this study assume that the data samples conform to standard normal distribution to estimate the standard deviation and adjust the maximum and minimum value, even to recalculate the EUI values of those 30 categories. The upper boundary values of 10%, 20%, 30% and the energy efficiency may be a reference for energy consumption management. The summer EUI values take 37.14% to 43.08% in the whole year’s value. This shows that the increasing air-conditioner working hour caused by the hot weather, and the emission heat of air-condition will raise the outside temperature, and thus causes energy-wasting vicious circle. The summer EUI value can be a reference for power company to adjust the electricity price. The building type with the highest EUI value is convenient store (1661.61 kWh/㎡．a), and the second is chain fast food restaurant (1458.20kWh/㎡．a), two of whose values are over 1000(kWh/㎡．a). The ones whose values lied between 500 to 1000(kWh/㎡．a) and 300 to 500(kWh/㎡．a) are all business categories. Even the EUI value of common chain retail sale store owns the value of at least 400k (kWh/㎡．a). These results show that the EUI of business categories take the most proportion in energy consumption, and it will be unwise to overlook this fact. The public sector organizations, whose values lied most between 150 to 300(1661.61 kWh/㎡．a), are the perfect target for the government to establish energy efficiency strategy, wherefore these organizations owns the most potential on energy saving work even they are not the most energy consuming categories. Educational institution and housing’s values take the part of lower than 60(kWh/㎡．a). Despite that it is the least energy consuming building type, and owing to the fact that the housing building take the most area in society, proper energy managements carried out on these areas can not only be efficient, but also play a key role on Education and Propagation of energy saving.
