1. Christian Hödl Lisa Koch Christine Rossegger Lisa Thalmaier Exploring our lifestyles and energy services

2. Content  Influences of our lifestyles on:  Production  Mobility  Housing  Evaluation of the questionnaires

3. Production – energy consumption

4. Production – CO2-emissions

5. Production – energy services

6. Production Survey on energy efficiency  High importance of energy efficiency in 48% of the companies  potential for the reduction of energy consumption was in most cases estimated between 0 - 15%  Problems with the implementation are often connected with information problems or financial problems

7. Mobility  motorisation rate of passenger cars  all European states, except Germany, increased their motorisation rate  Austria: at least one car per two inhabitants  reflects the questionnaire

8. Mobility  passenger transport by rail  F and D had the largest numbers of passenger kilometres  AUT is one of the five states, that reported the highest average distances traveled by rail  apart from six states, every mentioned country showed an inreased use of rail transport per inhabitant

9. Mobility  passenger transport by air  increase of air transportation in all states in the periode from 2003- 2008  between 2008 and 2009 a decrease of 5.9%, caused by the economic crisis  in April 2010 a decrease of 18% compared to the year before, caused by the Icelandic volcanic eruption

10. Housing Development of Energy services related to housing 1990 – 2009:  Austria’s gross inland energy consumption + 28,7%  Energetic end use without heating + 38,8%

11. Housing  Increasing factors (1990 – 2009)  Austria’s population  Number of main residence  Average size of living space  Energetic end use without heating  Energetic end use for heating was decreasing

12. Housing  Specific Electric Energy Services  Distripution of household´s total energy consumption in Austria: E.g. Household appliances and refrigerators are together accounting for almost 34%

13. Housing Internet  Our lifestyle is highly depending on the Internet  2006 server farms in US used 61 billions kilowatt-hours of energy (1,5% of Total)  1000 Google search requests are causing as much CO2 emissions as an average car produces per kilometer  In March 2009: 9 billion search requests only in the USA (12.000 car kilometers per hour )

14. Housing Reduntand energy use  Standby energy consumption: 4% of total energy consumption  Avoiding redundant thermal or special electric energy services by controls: 15% reduction  Our current lifestyle is very much dependent on the use of flows instead of building up stocks  We should invest much more in the quality of our buildings instead of using that much energy to provide energy services  Buildings with passive house standards could reduce final energy used to provide thermal energy services theoretically to 100%

15. Evaluation – Methodology and Challenges  Implementation of SPSS  Population of the analysis: 64 not all questionnaires were completely filled in  number of evaluated data per question varies  difficulties regarding the questions :  Standby electricity consumption: problems with the metering wrong data was excluded  European and Intercontinental flights: For some students it was not clear if a bidirectional flight should be counted as “1” or as “2”

16. Evaluation– Standby electricity consumption

17. Evaluation– Costs for heating and hot water

18. Evaluation– Local distances mobility profile Considering an 5km/h walking speed: 217 km/day

19. Evaluation– Long distances mobility profile

20. Evaluation– European and Intercontinental flights

21. Evaluation– Male vs. Female standby electricity consumption The female students consume approx. 23% more than their male colleagues

22. Evaluation– Male vs. Female local mobility profile Male students: larger distances by bike Female students: larger distances by bus, train and also by car
