摘要

台灣目前以電子業為主流，高科技電子代工為大宗，技術、資本及能源密集是電子產業的特色。
電子產業其製程多需再嚴苛的潔淨室空間生產，台灣位於亞熱帶區域，屬於海島型氣候國家，夏季平均溫度約28℃db ，平均相對濕度約78%。所以它們具有共通的特性如下列5點：
1.為維持製造工廠的無塵環境，故需要大量的空氣換氣量(Air Exchange Rate)。
2.為維持嚴苛的溫濕度要求(例如 24±0.5℃and 40±5 %RH) ，故需同時冷卻、加熱及加濕。
3.二十四小時生產、全日空調運轉。
4.製程機台發熱非常大，故單位負載大。
5.製程排氣量大，故需引進大量外氣，以保持正壓。
因此本研究經由能源局電子產品單位耗能指標，整理其36種電子產品於2009年間各產品之年產值。藉此得以回顧台灣目前電子業發展的方向及瞭解何種電子產業當前能耗最高；經統計得知2009年度其TFT -LCD面板、DRAM12吋晶圓、IC封裝業是當前產值最高的電子業，而最耗能的產業則是DRAM12吋晶圓、DRAM8吋晶圓及TFT -LCD面板(含CF)領先其他電子產業。希望該統計能提供業界、建廠設計者、建廠安裝者及ESCO(Energy Service Company)參考。

The electronics industry is one of the primary industries in Taiwan today, and high-tech electronic OEM (Original Equipment Manufacturing) comprises the majority of that industry. In general, the electronics industry requires technology and capital, and it is energy intensive.

The manufacturing process often requires high clean-room standards. Taiwan is a semi-tropical, island-climate country. The average summer temperature is around 28°C db, and the average relative humidity is about 78 percent. Therefore, electronics manufacturing facilities in Taiwan have five usual characteristics:

1.In order to maintain a dust-free environment, the clean-room air-exchange rate must be high.
2.To meet strict requirements of temperature and humidity control, such as 24±0.5°C and 40±5%RH, the ability to cool, heat, and control humidity is necessary.
3.Manufacturing takes place 24 hours a day, requiring constant use of climate-control equipment.
4.The machinery used in the electronics-manufacturing process generates a great amount of heat, so the load on the climate-control equipment is heavy.
5.During the manufacturing, air displacement is high, so it requires a great deal of external air to replace the displaced air.
This research utilizes the Unit Energy Consumption Index produced by the Bureau of Energy, Ministry of Economic Affairs, to investigate the annual output value of 36 types of electronics products in 2009 in order to better understand the current developmental direction of electronics industry, as well as reveal what types of electronics manufacturing consume the most energy. According to the results of the research, TFT/LCD panels, 12-inch DRAM wafers, and IC packaging had the highest output values in 2009. The manufacture of 12-inch DRAM wafers, 8-inch DRAM wafers, and TFT/LCD panels (including CF) resulted in the highest energy consumption. It is hoped that this study can provide a reference for the electronics industry, plant designers, plant installers, and energy service companies (ESCOs).
