世界各地面臨全球暖化，以及能量需求與價格的增加，因此該如何增加能源的使用效率以及能源節約的議題備受矚目，對於一般家庭而言，要進行節能的第一步是要暸解目前能源的使用狀況，在過去的用電表達方式往往可能只是紙面上的數據或是與社區之對比，這些並不一定能夠增加用戶的節電意識。
在利用建築資訊模型內建築相關參數的編輯有極高的自由度，在表現情境上卻有所缺失，本研究利用遊戲引擎動態呈現用電情況並實現互動式平臺以增加用戶的節電意識，本研究將家庭內電器分為兩種類型：一為被動式的群組型電器，用戶可以自行設定各個電器之組別，以表達群組型電器；二為被動式有順序型電器，此類型電器與電器的時間空間相關，有問題之電器，在遊戲引擎環境內表現出來，以此來增加用戶對自身用電行為的暸解及掌握，並激起用戶的節電意識，達到提醒用戶自身的用電。
本研究結合3D遊戲引擎與BIM相關軟體建置出一互動式系統，依照不同的用電樣式做出提醒以及呈現，並保有建築的完整性及真實性。

The world is facing global warming, increased energy demands and limited resources. Therefore, how to increase the efficiency of energy use is of high importance. For a typical household, this research assumes that understanding household power usage patterns is the first step and the only way to achieve energy savings. Previously, power consumption data are often aggregated and displayed on utility bills, which hardly increases the residents’ awareness regarding energy savings. In this research, Building Information Modeling (BIM) and Unity technologies were utilized to implement an interactive platform in order to show power consumption data sets and selected energy saving patterns. Two types of potential energy-saving patterns were realized in the proposed platform. One is about a group of passive appliances, which users can specify which appliance be incorporated into which group. This group of appliances should be turned on or off all together, and if any of the appliances in the group do not obey the rule, the platform will identify them and display the energy-saving tip in the 3D environment. The other is about a spatial group of appliances that their locations are inside the same room or zone. The platform will monitor the power consumption data set and once the given appliance is turned on (such as a security alarm), all the other appliances should be turned off. The platform can remind the residents of when and which appliance should be turned off, thus having the potential of saving energy for the household.
