關於節能

在看影片之前可以先到介紹網站看看這個組織。
這個影片討論了一些節能方式，本集主題是從建築結構下手。我覺得在頭跟尾女生講話時都還好，但是男生在講ppt時就很難，因為他速度比較快，又提到了一些比較專門的字，所以比較不好講。

Before watching the video, please go to see the homepage to check some information.
This video mainly discussed some methods to save the energy. The organisation arranged a topic per month; this one talked about the building. When I did the SI with this video, I reckon it was not too difficult to follow the lady in the beginning and in the end. What was more challenging was the speed and some glossary that I did not know.
