Residential Monitoring to Decrease Energy Use and Carbon Emissions in Europe

Transcription

1 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

2 OVERVIEW : Methodology Output Some examples of results Focus on consumer electronics Focus on lighting Discussion of results

3 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% > / Children older than / Children younger than / No children 80% 70% 60% 50% 40% 30% Multi Occupancy Building Single Family House 20% 20% 10% 10% 0% 1 0% 1

4 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

5 METHODOLOGY : Measuring equipment : Load profile power loggers Lighting loggers Consumption meters

6 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

7 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.

8 SOME EXAMPLES OF RESULTS Electricity consumption (kwh/year) Data derived from e-ster household energy auditing databank

9 SOME EXAMPLES OF RESULTS Electricity consumption (kwh/year) Data derived from e-ster household energy auditing databank

10 SOME EXAMPLES OF RESULTS Electricity consumption (kwh/year) Data derived from e-ster household energy auditing databank

11 SOME EXAMPLES OF RESULTS Washing machines : Estimated annual consumption (kwh/year) 69 washing machines metered, average estimated annual consumption 190 kwh/year Series

12 kwh/year SOME EXAMPLES OF RESULTS Washing machines : Estimated annual consumption (kwh/year) difference between type of household Mean = 162 kwh Mean = 246 kwh Mean = 240 kwh no kids kids <12y kids >12y retired Type of family Mean = 119 kwh

13 SOME EXAMPLES OF RESULTS Washing machines : consumption as a function of age of the appliance : Data derived from e-ster household energy auditing databank

14 SOME EXAMPLES OF RESULTS Washing machines : consumption as a function of household size : Data derived from e-ster household energy auditing databank

15 SOME EXAMPLES OF RESULTS Washing machines : consumption as a function of % of 40 C washing : Data derived from e-ster household energy auditing databank

16 SOME EXAMPLES OF RESULTS Clothes dryers : consumption as a function of household size : Data derived from e-ster household energy auditing databank

17 SOME EXAMPLES OF RESULTS Clothes dryers : consumption as a function of appliance age: Data derived from e-ster household energy auditing databank

18 SOME EXAMPLES OF RESULTS Clothes dryers : consumption as a function of type of dwelling : Data derived from e-ster household energy auditing databank

19 SOME EXAMPLES OF RESULTS Clothes dryers : Comparison of consumption in the different EU countries : To be found in the Final REMODECE Report

25 % standby consumption SOME EXAMPLES OF RESULTS Standby consumption (%) e-ster residential energy audit ( ) REMODECE measurement campaign (end ) PC TV

26 FOCUS ON LIGHTING Comparison of annual energy demand for lighting in the different EU countries : Annual energy demand kwh/year RO PT NO 946 IT HU 224 GR 767 FR DE DK CZ 518 BG 783 BE

27 Country FOCUS ON LIGHTING Comparison of installed wattage for lighting in the different EU countries : Installed wattage PT RO PT NO IT HU GR FR Secondary Living room DE DK CZ BG BE Total installation Watt

28 Electricity consumption (GWh) DISCUSSION OF RESULTS Reference case consumption Belgium derived by stock model Oxford (Lane K. & De Groote W. 2001) : 16,000 14,000 Misc 12,000 10,000 8,000 6,000 Lighting CE Cooking 4,000 2,000 Wet Cold

29 DISCUSSION OF RESULTS Reference case Belgium REMODECE : To be found in the Final REMODECE Report

30 Electricity consumption (GWh) DISCUSSION OF RESULTS BAT case consumption Belgium (Lane K. 2001): Misc Lighting CE Cooking Wet Cold

31 DISCUSSION OF RESULTS BAT case consumption Belgium REMODECE : To be found in the Final REMODECE Report

32 DISCUSSION OF RESULTS Shortcomings and uncertainties REMODECE : Sample seize Sample representativeness (socio-demographic, only Flanders and Brussels, )
