Buildings sector is the largest single energy end-user in the EU. There are numerous possibilities to save energy in buildings. This research deals with the analysis of the possibilities to save energy in buildings of northern latitudes by applying a passive solar energy technique. The article presents results of solar radiation monitoring in Vilnius for a 12 years period and assessment of the possibilities to save heat energy. Data could be used in designing solar houses, calculating passive solar energy gains and evaluating CO2 emissions reduction.
