碩士 === 南台科技大學 === 電子工程系 === 97 === The aim of this research focuses upon the government policy on energy savings and carbon reductions stemmed from the increased shortage of global resources. After the Transformation of the Taiwan Railway into a MRT-type railroad, Taiwan Railway Administration drafts to draw a recommended scheme from reconstructing elevated train stations for maximization of utilities in terms of reduction of electricity consumption, operating costs and abysmal destruction for environments. This study explores Taiwan Railways Sijhih Station case, which is sponsored by U.S Department of Engery and Electric Power Research Institute (EPRI) money and credited for J.J. Hirsch & Associates and Lawrence Berkeley National Laboratorys’ (LBNL) collaboratively developed eQUEST model, constructing computerized simulation model of architectural framework and air conditioning at this station. Based on this simulated model, hourly energy consumption data can be retrieved for extrapolation in order to analyze the annual electricity & carbon consumption against the required benchmark as a norm for energy savings. The research also simulated variation under different energy saving strategies, which include the increasing of indoor temperature, the improving of chiller efficiency, and the reducing of illumination and compared the energy consumption between normal and energy saving models. As the result, the best energy conservation model can reduce21.51% in building energy consumption and 25.88% in air conditioner energy consumption. Evaluating the individual saving model, the best one is to reduce of illumination which can reduce14.03% in building energy consumption and 8.42% in air conditioner energy consumption and the second one is to increase of indoor temperature of the station which can reduce 3.58% in building energy consumption and 8.63% in air conditioner energy consumption.
