  • How do we get the list of devices ?
  • To what criteria does an appliance gave to comply ?
  • To what criteria does an appliance gave to comply ?
  • To what criteria does an appliance gave to comply ?
  • To what criteria does an appliance gave to comply ?
  • If a device complies with criteria for further study, this is what we’re gonna do
  • If a device complies with criteria for further study, this is what we’re gonna do
  • When the appliance has been studied, we can focus on the design and improvement possibilities / looking more inside the device
  • When all is known about the appliance, a warning is given out and communications with the developer are started. Either they improve their practice, or we can start naming and shaming

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

    3. 3. Relevance of an Early Warning System<br />Power: up to 32 W<br />EcodesignDirective: max. 13 W<br />Would have saved 375 GWh annualy<br />120.000 tonnes of coal<br />280.000 tonnes of CO2<br />
    4. 4. Research Question<br /> “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?”<br />
    5. 5. Intermediate research questions<br />How should upcoming and potentially inefficient household appliances be identified? <br />Based on which criteria should the household appliances be selectedand how can the necessary information for these criteria be obtained? <br />How should the EWS obtain information about the total energy impactof the selected household appliances?<br />How should energy saving options for inefficient appliances be identified and evaluated? <br />How should policy advicebased on the findings about upcoming household appliances be reported, by whom and to whom? <br />Who should run the EWS? What information should it exactly provideand to whom?  <br />

    20. 20. Internet Modems<br />Upward impact: 3,5% – 6,1% per modem<br />Broadband internet diffusion nearly 90%<br />Turn modem off<br />Minimizepower consumption<br />
    21. 21. Home Servers<br />Fits in the digital media trend<br />One additional PC per household<br />Always on, impact between 3% and 21%<br />Any PC can function as a home server<br />Design to minimize power use and idle time<br />
    22. 22. Desktop PC Video Cards<br />Better graphics  more power<br />Impact between 0,3% and 2,8%<br />Consumers need to match their needs<br />Very few consumers actually need high end cards<br />Low and medium end cards impact up to 0,3%<br />
    23. 23. Boiling Water Tap<br />
    24. 24. Set-Top Boxes<br />Digital TV separate decoders<br />Energy usage seems unthought of<br />Uses between 2,8% and 4,3%<br />Ecodesign Directive should solve this issue<br />
    25. 25. Espresso Machines<br />Hot-reservoir machines consume up to 2263 kWh or 64%<br />Effective power management can save up to 1/2 of consumption<br />Filter pad machines save energy<br />Like black coffee ?225 g of coal per cup !<br />
