Motivation

People usually forget to turn off the air conditioner in public place (e.g. 資工系館 ), such as Seminar room, classroom.

If the air conditioner were not closed by the person who used the place last time, and the next using time is after three days ……

Current Situation

By deploying the vent temperature, we know: whether the AC controller is turn on or not If the vent or the pipeline is abnormal Which room needs an improvement

By CSIE and AC(Host_1) power consumption : In non-activity section, the power consumption of chill

ed water system is high and waste

Prof. Jane’s advice

偵測出系館內用電量異常 ( 浪費 ) 的情況，然後改善 ( 修理 , 給建議…… )

將所蒐集到的資料整理並展示出，讓每個人都能看懂 (eco-visualization)

建構出一個 general 的節能系統，以 CSIE 為一個例子驗證

Problem Definition

1. Construct an energy conservation system (for AC) to avoid the non-necessary electricity using

Case Study

在資工系館 3F (4F, 5F) 的研討室部署 sensors 收集資料，以找出沒人使用卻開著空調的情況 ( 浪費時如何提醒 or 關掉 ) ，減少浪費的情形 部署 taroko 監測出風口溫度 部署 camera 監測人數 Light sensor ??

經由空調電錶推算出一間研討室的空調耗電量

接著將此機制推廣至各種房間 ( 實驗室，教授室…… )
