Abstract [en]

Measurements of electricity, hot water consumption and indoor temperatures were carried out in 24 apartments during the years 2005 and 2006. Buildings located in Västerås (Sweden) are characterized by the fact that energy costs are included in the rent. Data obtained from the company renting out apartments, “MIMER”, was analyzed in order to find out if there were any general trends describing the connection between the level of surface area, number of rooms, or the main driving force behind is the individual behaviour of tenants. It was found that the analysis by various parameters is as important as the analysis of each individual apartment. Some tendencies were well defined such as increase of total electricity consumption during the winter months and lowest both electricity and hot water consumption in June and July. The number of rooms at equal surface area could not be accepted as a pattern of electricity consumption. Bearing in mind the interactive contact between the energy company and the respective tenants, a positive trend of lowering both studied parameters was well manifested when a comparison of data obtained during 2005 and 2006 was carried out. Our results confirmed the importance of indoor temperature measurements as well. Further improvements in company-tenants relations in terms of more detailed mutual information would probably change tenants’ behaviour thus improving energy saving tendency in both buildings.

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.
