  1. Karbon Demonstrator SAB - Nov 2009 www.clarity-centre.org

  2. The EU 2020 Targets 20% greenhouse gas reduction vs 1990 levels. May increase to 30% depending on 2009 Copenhagen meeting. Targets split between trading & non-trading sectors. Large industry vs transport, residential, waste, small industry. Current EPA projections point to overshoot. Approx 18% (with-measures) - 41% (baseline)

  3. Celtic Tiger Hangover During the Celtic Tiger ...... our emissions soared ... Now that the party is over ...Carbon footprint 1.5x EU average. The Benefits of Recession Is the recession the treatment to our carbon addiction? If everyone lived like the Irish we would need …

  4. Carbon Footprinting Measure to Improve Off-the-shelf sensors provide the beginnings of a comprehensive approach to personal carbon footprinting. Address 3 Key Areas Energy usage; waste & recycling; personal transport & health. Focus on Communication & Education Eventually leverage social media tools and recommender systems to engage individuals in their own carbon achievements.

  5. Hardware ZEM-30 Energy Monitor Connected to positive line of mains supply Every minute records: RMS/Peak/SAG current/voltage, Watt hours, real/apparent power Communication via Zigbee network

  6. Data Management Data recorded every minute Data anonymously uploaded to CLARITY central server (UCD) every 10 minutes Analysis tools used to extract information from uploaded data Data available to user for visualisation & reports or alarms Data can be used to take action, such as remote switching of appliance (later goal)

  7. CLARITY Deployments 19 domestic participants, 2 lab settings 15,840 sensor readings per house per day! We’re now gathering 2 MILLION readings/week Equates to over 120 million per year for 21 settings! Participants can view up-to-date info on web browser

  8. Sample Day

  9. Appliance Detection • From single sensor, can we identify device signatures? • Combination of Neural Network + Decision Table approaches

  10. How long does each shower normally last? Usually less than 10 minutes!!! Appliance DetectionUse Case: The Shower

  11. BACK FROM TRAINING GETTING READY FOR SATURDAY MUSIC SESSION Life Patterns Usr1 Usr2

  12. Visualisation No deep complex navigation Bright screen vs. dark screen main menu vs.

  13. Interactive Visualisation CONTEXTUAL COMPARISON COST TO USER HISTORICAL QUERIES APPLIANCE DETECTION

  14. 20x in the home, and also in the CLARITY labs

  15. Where are we going? So far: Close collaboration with Irish SME Significant volume of home deployments Appliance detection investigations Implementation of multiple interfaces We will continue this work, BUT thus far we’re just calculating carbon emissions from domestic energy consumption

  16. Acc2 Acc1 Acc3 Recognising activities from accelerometer • Consider any device recording accelerometer activity: cell phones, pedometers, etc. • We use SenseCam • a valuable validation & CONTEXT REINSTATEMENT tool • Tri-axes acc, logged every second

  17. Classifying Activities Driving = 88% Accurate Using a range of classifiers: Logistic Regression, Naïve Bayes, J48, SVM, Etc.

  18. More complete CO2 Estimation 2 simple sensors Domestic power logger Wearable accelerometer Use Case 1 user: Episensor + SenseCam 2 months: 963,000 Episensor power readings + 3,020,900 SenseCam acc readings Home Energy Usage CARBON Algorithm 40kgs CO2, €18.43 Results Published to CLARITY industry partners + appropriate journals SenseCam

  19. How to calculate CO2? • Domestic • 1 KW/H = 0.54055 kgCO2 = €0.17 • Driving • 8m 5sec = 1 litre = 2.3035 kgCO2 = €1.18

  20. Complete CO2 Picture on TV DRIVING CARBON/COST DOMESTIC CARBON/COST

  21. AAL and Karbon

  22. The Future Continue existing work on visualisation applications Focused investigations in appliance detection More in-depth investigations on carbon footprint Consider data from new sensors, e.g. CO2 output from landfill methane measurments
