4. What is the goal?
• EC goal is a 20% emissions reduction by
2020 as compared to 1990
• UK goal is 60% 2050
Challenging targets
Thursday, March 26, 2009
5. Issues
• 2020 is not far away (2/3 through)
• Lead times for “clean” energy supply long
• Lasting legacy of energy inefficiency
- 80% of refrigerators bought in 2007 will be in use in 2020
- less than 1/3 of industrial infrastructure will be replaced by 2020
- over 20% of cars bought in 2007 will be on the road in 2020
CapGemini survey and analysis

6. Leads to conclude
• Supply side will not be ready in time
• Humans are essential in solution
• Household efficiency must be a priority
- 25-30% of carbon emissions from households
- 80% of energy usage in households is heating
- EC projects 27% savings through efficiency in buildings
Change in household values will drive a larger lifestyle change,
thus reducing emissions across all areas of inefficiency.

7. What ingredients are
required?
• Measurement
- Metrics - what is being measured?
- Context - how do you compare to others and norms?
- History - how am I changing over time?
- Trust - can I trust this is real and personal?
- Granularity - is there enough detail to explain what is happening?
• Models
- Projections - how do today’s actions impact on tomorrow’s metrics
• Management
- Access - does information find me or do I find information?
- Control - can I take action?

- Access Control
• Public education: government led
• Energy efficiency projects:
voluntary/gov led

9. DEHEMS approach
• Energy performance measurement rather
than total consumption
• Community dimension to behaviour change
• Enabling easy, effective action

13. Living Labs
• Observations are real and dynamic
• Take requirements from end users
• Makes R&D market ready
• Plan 250 households, will exceed into 300
• Significant excess public demand (1000s
from limited exposure)
Thursday, March 26, 2009
14. Results
• People want to engage with issue
• Immediate impact in behaviour change
• New behaviour seem to be sustained
• Big scope for community functions
• People want to know more
• Target 20% savings is very achievable
Thursday, March 26, 2009
15. What next?
• Better management, access, models
• Appliance level metering, heating and
lighting energy, control functions,
remote management
• Carbon trading, Neighbourhood
League Tables
• Mashup with EcoMap
• Commercial partnerships
Thursday, March 26, 2009
16. Case: Policy application
Demand-side
• Manchester exploring emissions reduction reward
scheme to help drive household behaviour change
• Households earn points for lower emissions measured
through dashboard
• Points redeemed for energy efficient goods and
services; similar to Nectar, Club Card or Green Shield
Stamps
• Drives ongoing behaviour change by integrating energy
efficiency in consumer decisions
Thursday, March 26, 2009
17. Case: Policy application
• Targeting existing programmes, e.g. Warmfront
• Present comparison to local households for
recruitment into programmes
• Normalised comparison: e.g. similar household/
demographic/structure/dynamics
• Quantify benefits: those with/those without
intervention
Thursday, March 26, 2009
18. Case: Internet
• Ecomap with City of
San Francisco
• Mashup data from
satellite, census,
demographic and
DEHEMS
• Cisco, NASA
Thursday, March 26, 2009
19. Conclusion
• What gets measured -- at least -- can be managed
• Aligns economic and environmental motivations
• Visibility requires technology - step beyond current
• Development driven by users is critical
Thursday, March 26, 2009
20. Smart metering
• Principle application is billing - achieves supplier
objectives of 100% accuracy for remote billing
• Driven by energy companies
• Lacks most of the social change ingredients
• Not “open” environment for application creation
• Tech approach: replace current electricity/gas
meter, transmit data over GPRS nightly, increase in
billing accuracy
Thursday, March 26, 2009
21. Display units
• Isolated data collection - lacks Internet effect
• History is not presented easily
• Not an “open” platform for application creation
• Limited understanding
• Simple technology, limited action capability
