Residential Monitoring to Decrease Energy Use and Carbon Emissions in Europe Results from Survey Campaign in Belgium National Workshop September 19th, Brussels Organised by MINA-Raad
Results from Survey Campaign in Belgium Household details The REMODECE Questionnaire was programmed into a Web questionnaire. During 2006-2007, face-to-face interviews have been made, especially with families without internet connection. In November and December 2007 E-ster placed the questionnaire at their Web site, www.e-ster.be, where answers were collected. Other sites, such as the website of the Energy Agency of Flanders (Vlaams Energie Agentschap), www.energiesparen.be (Particulieren) and the Flemish Green Light Information Point and Endorser, GroenLicht Vlaanderen, www.groenlichtvlaanderen.be, did put links to this link.

Conclusions Compared to national statistical figures for type of building, and average consumption and data included in previous surveys, the REMODECE sample is evaluated to be good and representative in most aspects.
Conclusions Compared to national statistical figures for type of building, and average consumption and data included in previous surveys, the REMODECE sample is evaluated to be good and representative in most aspects. Some good options for electricity saving : Use the Eco program of the dishwashing machine Don t rinse the dishes before putting them into the dishwasher Use more cloths drying outside instead of tumble dryer Use a pressure cooker Defrost food in the refrigerator instead of in the microwave or the room
Conclusions Switch of modems and router along with switching of the computer Switch off Home Entertainment equipment with external (manual or automatic) on/off switches, in order to really switch off these appliances Make attention to buying of Energy Star computer equipment as very few have knowledge about this Use more multiple sockets with a switch to disconnect all appliances from the mains Try to increase the use energy saving bulbs and stop the rapid market transformation from use of incandescent to halogen lamps Replace old refrigerators (especially those with freezing cabinet) and freezers by A+ or A++ appliances
