Global development goes hand in hand with the continuous growth of energy consumption, leading to many environmental issues. However, people hardly understand their consumption as it's not visible, also there's a lack of accessible mechanisms for people to keep track of their usage.

The system aims to investigate people's needs and perceptions in terms of visualization to trigger sustainable behavior in their living environment.

I built a web application to visualize users' electricity usage through two separate types of artifacts:
1. Characters: use of panda and bamboo to represent consumption. Panda expresses its emotion based on usage amount in real-time, including four emotion states: happy - neutral - sad - cry. While Panda's emotion gives instant feedback for its owner usage, it is unable to give the overall information for a long time (e.g. a day). Bamboo is used to complement this aspect, it grows throughout the day based on the Panda's emotion (it shortens when the panda is sad, lengthens when the panda is happy)
2. Analytics: represent usage by detailed charts, showing detailed information on each category of usage by day

Group users are able to compare their consumption with other people in the houses through both characters and analytics.
