Nowadays we can see a high consumption of energy for transportations and in offices, for lightning, ventilation, computers etc. We also have a significant household consumption of electricity. However, in the future we can expect a trend where the houses are consuming significantly less energy for heating, with thicker insulation, four glass windows and better constructions giving less unwanted diffusion of heat due to leakages. In Vasteras city, the trend has been a reduced heat demand of approximately 1.5-2 % per year during the last 25 years. This means that the district heating sink has been reduced by 30 %. This makes district heating less competitive as the reduced heat demand give lower potential for electricity production in co-generation. Similar adequate measures should be performed in the field of household electricity consumption. As a first step and what is the aim of this report, sufficient data of electricity consumption along large periods of time should be accumulated and carefully analyzed in order to develop appropriate further electricity-saving measures. Data included in this study was collected from two buildings in Vasteras area over several years (from 2004 until 2008) and further comparatively analyzed and discussed bearing also in mind some complementary information gathered in form of a paper based questionnaires. The results of our study indicate that it is important to change patterns for ‘consumption’ of electricity. More emphasis should be made on two main research directions: a) detailed analysis of tenants’ consumption behavior; b) development of appropriate information tools that will offer the consumers a possibility to both get information about the electricity consumption in an easily accessible way, e.g. by displays with information that is easy to catch.
