Residential Monitoring to Decrease Energy Use and Carbon Emissions in Europe Some results from the measuring campaign National Workshop September 19th, Brussels Organised by MINA-Raad
OVERVIEW : Methodology Output Some examples of results Focus on consumer electronics Focus on lighting Discussion of results
METHODOLOGY : Sample : 100 households in Flanders and Brussels As representative as possible (household seize, type of dwelling, number and age of children,.. Type of family Type of dwelling 100% 100% 90% 90% 80% 70% 60% 50% 40% 30% >65 19-65 / Children older than 12 19-65 / Children younger than 12 19-65 / No children 80% 70% 60% 50% 40% 30% Multi Occupancy Building Single Family House 20% 20% 10% 10% 0% 1 0% 1
METHODOLOGY : What has been measured? Total electricity consumption of the household during 2-4 weeks Load profile or consumption of main electric appliances (not : coffee machines, kettles, microwaves,..) Load profile of main lights / lamps
METHODOLOGY : Measuring equipment : Load profile power loggers Lighting loggers Consumption meters
OUTPUT : 1. Database with socio-econnomic variables (hh. size, age of children, type of dwelling, ) Total consumption / load profile during 2-4 weeks Measured consumption / load profile per appliance and per lamp Database can be used for bottom-up modelling of electricity demand and for comparisons with other EU-countries 2. On-line tool for consumers to estimate their consumption and get advise on how to reduce it
SOME EXAMPLES OF RESULTS Consumption per end-use for total sample (including additional data from the e-ster houshold energy auditing databank): 1% 5% 6% 9% 18% 15% 10% 12% 9% 8% 7% washing machine clothes dryer dish washer refrigerator freezer consumer electronics lighting cooking water heating standby Misc.
