摘要

因應鐵路地下化，車站也因鐵路地下化改成地下車站，結果為大量電力用於空調及照明，能源也成為車站之重要營運成本。為解析地下化車站之節能潛力，本研究採用美國能源部所發展之eQUEST動態建築耗能模擬軟體，建構車站建築物及耗能設備之模型，分析全年之逐時耗電，及節能方法之效果。本研究發現空調主機、風機、泵及照明皆為主要耗能項目，占總耗電約達九成。本研究針對大型地下車站做人數外氣需量控制及照明節能，得到顯著的節能成效。以車站區域（不含軌道區）估算台北車站EUI值約425kWh/m(平方公尺).yr，某新車站A在未改善前EUI為366kWh/m(平方公尺).yr，在經過節能改善後EUI可降低至277kWh/(平方公尺).yr，節能效果可達24%。

Railway goes underground in metropolitan area results in many underground train stations. As a result, air-conditioning and lighting have become major energy consumption items for the railway operation. To analyze the energy saving potential, the dynamic building energy program developed by the US DOE, eQUEST, was used to set the building model. Energy consuming equipment was then modeled with hourly energy analysis in a typical year. It was found that chillers, fans, pumps, and lighting make the major building energy, constitute about 90% of the total power consumption. Demand control of outdoor air and lighting energy saving are found to have significant energy saving potential. Consider only the building area of the station (exclude the railway section), the EUI for a Taipei station was calculated to be 425kWh/m^2.yr. EUI of a new underground station was analyzed to be 366kWh/m^2.yr. After taking the energy saving measures as proposed, EUI can be lowered to 277kWh/m^2.yr, with an annual saving of 24%.
