大專院校教學館舍耗能改善之研究---以交通大學工程二館為例

Abstract

本研究案例交通大學工程二館於96年進行整修後，總用電量大幅下降，本研究經由兩種估算模式，得到交通大學工程二館整修前後之用電量比例，分析其用電量下降原因，並經由研究案例各空間EUI值評估與分析，找出學校建築節能改善的空間，進行節能效益評估並提出改善建議。

工程二館主要用電結構為照明類、電腦類、空調類、其它動力類及電梯五項。估算模式一計算結果為照明占30.10%、電腦類占25.07%、空調類占36.46%、其它動力類占7.60%，電梯占0.78%；估算模式二計算結果為照明占27.95%、電腦類占27.97%、空調類占33.85%、其它動力類占9.51%，電梯占0.72%。工程二館各空間EUI值加總後介於45.266~67.139之間，與工程二館97年實際EUI值64.78及98年EUI實際值53.825相符。工程二館照明設備改善評估結果，T5燈具省電效益為20.78%。

The electrical consumption of this study National Chiao Tung University engineering building2 significantly descended after renovating. This study through two kinds of estimate mode to get the electrical consumption proportion of National Chiao Tung University engineering building2 to analyze the reason of descended electrical consumption. Also through analyzing and estimating the energy use index (EUI) of this study each space to find the energy improved space of school architecture to offer the energy conservation benefit evaluation and improve suggestion.

The five mainly power structure of engineering building2 is illuminating, computer, air conditioner, other power and elevator.By estimated result of estimate mode I, illuminating occupied 30.10%, computer occupied 25.07%, air conditioner occupied 36.46%, other power occupies 7.6%, elevator occupies 0.78%. By estimated result of estimate mode II, illuminating occupied 27.95%, computer occupied 27.97%, air conditioner occupied 33.85%, other power occupies 9.51%, elevator occupies 0.72%.The sum of engineering building2 each space energy use index (EUI) is between 45.266~67.139, equating with the 97 year energy use index (EUI) of engineering building2 64.78 and the 98 year energy use index (EUI) of engineering building2 53.825. By analyzing result of the lighting equipment improvement, the energy-saving performance of T5 lamp is 20.78%.
