PowerZee is an application designed to save energy. Many successful behavioural economics/sociology inspired experiments on nudges show the potential for energy savings.

NTU along with industry partner ENGIE Lab Singapore (previously known as GDF SUEZ) embarked on developing a smartphone application for interactive user engagement using the sociological concept of nudging and a gamification based approach.

PowerZee application main features:

​• Combining concepts from sociology and gamification elements to foster energy conservation

• Bridging technology and behavioural science


Objectives and Methodology

Main objectives:
a) foster sustainable behaviour practices
b) raise awareness about energy consumption

A sociological study was done after the first experimental phase of PowerZee from mid-February until mid-June 2015. Quantitative and qualitative methods were used for study 1:
• 7 face-to-face interviews
• Workshop with 15 students
• Online survey with 700 participants


A high level of activity was registered when the first version of the application, PowerZee, was tested on NTU campus between February and June 2015 with over 2000 players.

The performance of the application evaluated with 2 studies showed the following results:

​Study 1: Gamifying Energy Conservation Behaviours

• PowerZee increases awareness about energy consumption and fosters eco-friendly behaviour
• NTU could save up to 5% of the total consumed energy using PowerZee


Study 2: Socio-interactive media that save energy with high life-comfort

• Users were attracted to features that offered tangible, immediate results and enjoyed learning ways to improve their energy – savings behaviour

ENGIE and ERI@N are currently working on the next version of PowerZee. The results of the above study is being used to make the application more useful and impactful. The new version of PowerZee will be launched at NTU in 2017.
