  • Digital Environment Home Energy Management System

    1. 1. Digital Environment Home Energy Management System Clive Eisen - CTO Hildebrand Thursday, March 26, 2009
    2. 2. Our involvement in Green ICT DEHEMS BEPMS Residential energy Commercial building management energy management € 2.97MM €2.75MM Thursday, March 26, 2009
    3. 3. DEHEMS Consortium • • Manchester City Council [United Kingdom] University of Rousse [Bulgaria] • • Technical University of Cluj-Napoca Birmingham Council [United Kingdom] [Romania] • University of Coventry [United Kingdom] • Clicks and Links Ltd [United Kingdom] • The Centre [Belgium] • Hildebrand Technology Ltd [United Kingdom] • University of Salford [United Kingdom] • Bristol City Council [United Kingdom] • Corinex Communications [Slovakia] Manchester City Council and Manchester Digital Delivery Authority (MDDA) - Coordinator • Plovdiv Municipality [Bulgaria] Commenced - June 2008 • Duration - 30 months Ivanovo Municipality [Bulgaria] • Institute e-Austria Timisoara Thursday, March 26, 2009
    4. 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. 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 Thursday, March 26, 2009
    6. 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. Thursday, March 26, 2009
    7. 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? Thursday, March 26, 2009
    8. 8. Current landscape Measurement • Smart meters: energy company led - Metrics Context History Trust Granularity Models • Electricity display devices: - Projections Management consumer led - Access Control • Public education: government led • Energy efficiency projects: voluntary/gov led Thursday, March 26, 2009
    9. 9. DEHEMS approach • Energy performance measurement rather than total consumption • Community dimension to behaviour change • Enabling easy, effective action Thursday, March 26, 2009
    10. 10. Demo Version 1.0 DEHEMS Dashboard Thursday, March 26, 2009
    11. 11. Energy in various units with comparison Realtime power measurement & comparison Data driven tips 24 hour history minute by minute Thursday, March 26, 2009
    12. 12. Models Context Metrics Trust Granularity Context Management History Context Trust Thursday, March 26, 2009
    13. 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. 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. 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. 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. 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. 18. Case: Internet • Ecomap with City of San Francisco • Mashup data from satellite, census, demographic and DEHEMS • Cisco, NASA Thursday, March 26, 2009
    19. 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. 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. 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 Thursday, March 26, 2009
    22. 22. Impact assessment £500 £375 • Past 4 years electricity costs have risen 61% £250 • 20% savings amounts £125 to £80 per year £0 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 BERR Quarterly energy prices table. 23 December 2008 Thursday, March 26, 2009
    23. 23. Brain science • Commitment and Consistency • Liking • “Wired” Behaviour • Social Proof Thursday, March 26, 2009
    24. 24. System: Cycle 1. Thursday, March 26, 2009
    25. 25. Demand Outside DEHMES • Online questionnaire produced 1000 expressions of interest • DEHEMS will only cover 250 homes in specific cities • energyhive.co.uk created to satisfy demand Thursday, March 26, 2009
