1. Designing an Early Warning System for domestic appliances Presentation of results Joost van Barneveld Marnix Brinkman Jens Haakman Tom van Tol Frank Wilbrink July 2nd2010 Commisioned by Supervised by Dominique Tappy Luis Janeiro Sible Schöne Kornelis Blok

2. Contents Introduction Research Methodology EWS Methodology Results Recommendations Conclusions Question

3. Relevance of an Early Warning System Power: up to 32 W EcodesignDirective: max. 13 W Would have saved 375 GWh annualy 120.000 tonnes of coal 280.000 tonnes of CO2

4. Research Question “What should the design be of an Early Warning System for the Netherlands that can identify and select upcoming household appliances based on their additional energy use and potential saving options,in order to facilitate preventive policy making?”

5. Intermediate research questions How should upcoming and potentially inefficient household appliances be identified? Based on which criteria should the household appliances be selectedand how can the necessary information for these criteria be obtained? How should the EWS obtain information about the total energy impactof the selected household appliances? How should energy saving options for inefficient appliances be identified and evaluated? How should policy advicebased on the findings about upcoming household appliances be reported, by whom and to whom? Who should run the EWS? What information should it exactly provideand to whom?

10. 10 Identification Brainstorm Magazines Other methods Retail stores Trend watchers Internet sources

11. 11 Selection Appliances should be Dutch New Consumingenergy Excludedfrom the EU EcoDesign Directive Impact the household energy budget for > 0.5% =

12. 12 Selection - Example Waterbed Impact of + 3.1% on energy budget of 3500 kWh Significant market penetration Not new, no growing market penetration Set-Top-Boxes Impact of + 1.4% New and growing market penetration

13. 13 Selection - Results Shortlist: top-10 appliances Selectionbyclient: Prove usefulness of an EWS High profile products such as STBs and Modems Novelty kitchen appliances (Espresso, Quooker®)

14. 14 Selection - Results

15. 15 Energy Use Analysis Power and usage statistics Off Standby idle Operational/on Replacement of appliances Market penetration

16. 16 Energy Use Analysis Impact=Off, Standby, Idle, Load(Enew appliance−Eold appliance)3500kWh×Market penetration

17. 17 Energy Savings Analysis Avoidable standby use? Switched off? Best practice? High power consumption?

18. 18 Reporting Three page report per appliance Description Energy consumption and usage Impact assessment Savings recommendations

20. Internet Modems Upward impact: 3,5% – 6,1% per modem Broadband internet diffusion nearly 90% Turn modem off Minimizepower consumption

21. Home Servers Fits in the digital media trend One additional PC per household Always on, impact between 3% and 21% Any PC can function as a home server Design to minimize power use and idle time

22. Desktop PC Video Cards Better graphics  more power Impact between 0,3% and 2,8% Consumers need to match their needs Very few consumers actually need high end cards Low and medium end cards impact up to 0,3%

23. Boiling Water Tap

24. Set-Top Boxes Digital TV separate decoders Energy usage seems unthought of Uses between 2,8% and 4,3% Ecodesign Directive should solve this issue

25. Espresso Machines Hot-reservoir machines consume up to 2263 kWh or 64% Effective power management can save up to 1/2 of consumption Filter pad machines save energy Like black coffee ?225 g of coal per cup !

26. Game Consoles New generations Impact XBox 360, PS3 up to 4,9% – 5,7 % Semiconductor innovations Don’t use for DVDs uses 125 – 173 Watt versus 13 watt

27. Air Refreshers Impact between 1% - 4% Increasing market penetration due to allergies Multiple devices per household Some functions like lights can be removed

31. Actors

32. Data Acquisition Consumers Large quantities, less reliable Professionals Marketpenetration ? Data may be biased Introduces budget issues Legislation Effective Slow • Manufacturers • TNO • GfK EWS Database

33. Operation An NGO should operate the EWS Neutral party Professional organisation Can attract funds Actor targeted warning Manufacturers: design recommendations, ranking Consumers: website, newspaper article NGOs: Factsheets, press kits Government: legislation advice, climate impacts
