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

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

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

Adjusting to total population
Single and pairs without children 60 % in Norway – 41% for Washing machines Norway
Two parents with one or more children 28% in Norway – 49% for Washing machines Norway
Retired and other households 12 % in Norway – 9% for Washing machines Norway
In Remodece, the values are adjusted to the total population demographics

Ownership of each appliance type
Data from SSB “Formålsfordeling av husholdningenes elektrisitetsforbruk i 2001
Are used for white goods, refrigerators, freezers, water heaters etc.
Medienorge SSB Facts of Norwegian mass medias
Are used for TVs, Mobil telephone chargers, PC, Laptop, Internet, DVD players, cable TV etc.
Estimates showing annual energy consumption based on data from metering campaign, are multiplied with the typical number of appliances per household.
21SINTEF Energy Research
Statistics for each appliance type
Estimate of expected value kWh/year Max value (max consumption kWh/year) Min value Standard deviation kWh/år Confidence interval
Shows +/- interval for 95% probability of expected value Similar values are estimated adjusted for total
demographic data 1-2 person in household (60%) 2 or more persons (28%) Retired people and others (12%)
