Exploring our lifestyles and energy services

Content

Influences of our lifestyles on: Production Mobility Housing

Evaluation of the questionnaires

Production – energy consumption

Production – CO2-emissions

Production – energy services

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

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

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

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

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%

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

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%

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 )

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%

Evaluation – Methodology and Challenges

Implementation of SPSS Population of the analysis: 64

not all questionnaires were completely filled innumber 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”

Evaluation– Standby electricity consumption

Evaluation– Costs for heating and hot water

Evaluation– Local distances mobility profile

Considering an 5km/h walking speed: 217 km/day

Evaluation– Long distances mobility profile

Evaluation– European and Intercontinental flights

Evaluation– Male vs. Female standby electricity consumption

The female students consume approx. 23% more than their male colleagues

Evaluation– Male vs. Female local mobility profile

Male students: larger distances by bikeFemale students: larger distances by bus, train and also by car
