"It is difficult to reach targets of 10 to 20 % power savings for industrial products and motor vehicles, but it is easy to obtain considerable savings with little effort for buildings," notes Lin. At the same time, because Taiwan's buildings have a lifespan of 40 or 50 years, the impact of power savings is long-term.
「工業產品、車輛要達到 10 % 到 20 % 的節能目標已很不容易，建物卻可輕易地事半功倍，」同時，由於台灣建築物的平均壽命達四、五十年，節能效益更是長遠。
