Sustainable HCI
- Motivating pro-environmental behaviour through technology-enabled feedback
Social Norms
- Utilising peer-pressure and social competiveness to bring about reductions in energy usage
By combining above concepts we target behaviour change for energy consumption using online social applications

5. Domestic Energy Usage
UK domestic energy accounts for approx 30% of total energy expenditure in 2008

6. Home Energy Meters
Meter location Flats, apartments difficult to access or inaccessible
Energy is intangible
Understanding traditional meter readings

7. Home Energy Monitoring

• Basic presentation of energy data
• 8. Limited interaction
• 9. Closed systems with no social data sharing
• 10. Limited online applications
• 11. Bound to proprietary software
