Abstract [en]

Sufficient data of electricity consumption during large periods of time are accumulated and analyzed in order to develop appropriate electricity-saving measures. An important first step is to analyze and identify buildings/households that have an energy saving potential. In this work an evaluation of monthly electricity consumption data was conducted in identical buildings in the city of Vasteras in Sweden. Different behavioral consumption profiles have been analyzed using information from two sources: technical data of electricity consumption and behavioral parameters for each household obtained from a questionnaire survey. The questionnaire was formed by three groups of questions which concerned residents' characteristics, type and usage of electrical appliances, and attitudes towards energy consumption. The results show that electricity consumption profile of individual household can be mostly related to a given parameter. For example, the total household's income resulted one of the important factors determining the consumer behavior and as a rule is related to higher electricity consumption. Another important conclusion of our questionnaire-based analysis is the necessity for more detailed information about household/tenants behavior specifying the technical features of appliances for a given household.

Abstract [en]

Energy consumption is on a constant rise with domestic use contributing substantially to the overall consumption. The population growth along with ever increasing comfort levels and daily appliance usage are driving the domestic electricity demand to higher levels. Targeting domestic consumption is thus of great importance if global consumption is to be lowered. This involves understanding and changing consumers’ behaviour, awareness and increasing their knowledge on the subject of energy use.

In this thesis various factors determining household energy consumption such as dwelling size, income and number of occupants have been found alongside consumer behaviour to influence consumption the most.

Energy awareness, related interest and knowledge have also been considered when trying to explain differences in household consumption patterns.

Despite all possible characteristics and factors, the largest differences in energy consumption are found between individual households.

Providing feedback and information to households has been proven effective when addressing the issue of reducing domestic energy use. In this thesis, the effectiveness of three of the most popular ways of currently delivering feedback and information on energy consumption (displays, websites and bills) have been investigated by analyzing consumption patterns before and after their implementation. Consumers living in apartments that followed their consumption through the web based feedback were the ones that achieved the greatest electricity reductions (17,5%) when compared to the years before the website.

In order to provide effective feedback, with long lasting results that would keep consumers interested, several parameters have been proposed to be included when developing feedback and information. The type of dwelling (house or apartment), the age of the occupants, their level of education, income and their energy awareness and interest are the main determinants of feedback preferences.

The findings presented in this thesis contribute to a better understanding of households’ energy consumption patterns closely related to their characteristics, behaviour, interest and awareness, and also provide ways of improving the development of consumption feedback and information.
