1 SINTEF Energy Research 1 Remodece meeting March 2008 Nicolai Feilberg WP5: Methodology for Calculation of potential savings

2 SINTEF Energy Research 2 WP5 Analysis Metering campaign Calculation of Present state Norway

3 SINTEF Energy Research 3 Status metering campaigns Data received from Bulgaria 100 households Romania 8 households France 103 households Italy 1 households Denmark 1 households Portugal 92? households Czech 100 + households Germany 100 households (file structure problem) Norway 100 households, 90 finished analysed, 10 still registering

4 SINTEF Energy Research 4 Metering campaign in Norway Equipment used 125 standard Power detectives 5 electric cooker meters 16 house centrals Also to be used is 30 accumulating energy meters Problems: Late arrival of equipment Radio transmission problems Exterior antenna might solve problems Reset after power shortage

5 SINTEF Energy Research 5 Launcher Power Detective launcher Programming PowerDetectives to be placed in a house Use of codes to uniquely indentifying kind of appliance, enables cross country comparisons Storing of personal data file along with the Power detective files so that all information is available for analysis: Age of persons Number of persons in age groups Climate House types Data are stored on SD card, used in the metering central
