The aim of the research was to analyze the heat energy consumption in public buildings managed by the Riga City Municipality in the year 2008. The collected information contains the data about more than 400 not renovated buildings and buildings after partial renovation: windows condition, heat energy consumption, electric energy consumption in the heating season and warm season, ventilation total power with and without air conditioning systems. The data were analyzed dividing all public buildings in twelve groups. They are: schools, special status education schools, academy of music, day-care centres, hospitals, libraries, cult buildings, recreation centres, local government buildings, museums, sport centres and shelters. Our analysis focused on the heat energy consumption in: a) not renovated buildings with simple windows divided in two-panes with two separate wooden frames with the heat transmittance U≥2.5 Wm-2K-1; b) partially renovated buildings with energy-efficient double-pane Windows made of polyvinylchloride with the heat transmittance U≤1.8 Wm-2K-1. At the beginning we compared the heat energy consumption in each building group with Windows covering more than 20% and less than 20% of the building facades. We have analyzed the data for each group separately. Our analysis shows, that partial renovation: heat insulation of buildings with windows change in buildings does not give heat energy consumption economy, but in most part of cases made it even bigger.
