This work presents the selected results of examinations connected with an annual energy consumption CH and annual final energy demand Qk,H for heating and conducted on the group of educational buildings. The presented analysis and its results regard the group including 46 of 50 educational buildings, which form a municipal group of the buildings of this type and in which the educational institutions are located. The purpose of presented analysis was to examine the influence of possible occurrence and level of differences between the annual energy consumption CH and annual final energy demand Qk,H for heating of examined buildings. The realization of this purpose is the basis for further research and analysis aimed at determining the dominant reasons of mentioned differences, establishing their level and propose a calculative method for reducing the differences between the values “picturing” the thermal needs of educational buildings in actual (energy consumption CH) and theoretical (final energy demand Qk,H) conditions.
