Why DEHEMS? Supply side will not be ready in time Humans are essential in solution Household efficiency must be a priority % 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.

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?

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

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)

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

System: Cycle 1.

Demand Outside DEHEMS Online questionnaire produced 1000 expressions of interest DEHEMS will cover 250 homes in specific cities (Manchester, Birmingham, Bristol, Plovdiv, Ivanovo ) 3 cycles – test, refine, measure

Engaged Communities People need to be a real community not just a convenient one They have to be willing to contribute qualitative as well as quantitative data Timescales: for testing, for behaviour change

Challenges Existing technology isn’t always suitable New technology (and software) delays can be a problem Lots of specialist skills are required (installation, education)

The Future Existing technology isn’t always suitable New technology (and software) delays can be a problem Need for specialist skills on the pilot
