The paper presents the structure and indices of the annual
energy consumption in educational buildings subject to comprehensive thermal retrofitting. Seven buildings were analyzed; the energy consumption for heating and ventilation, hot
water preparation, and built-in lighting was analyzed in each
of them and, in the case of one structure, also cooling. The
indices of the usable, final, and primary energy consumption
were analyzed. The values calculated were compared to the
requirements of the energy standards in force in Poland. The
percentage shares of the above-mentioned energy demands
of each of the buildings investigated are given in the total
energy performance. Within the investigation, we evaluated
the shares of the particular building services in the total energy consumption and determined that even after the thermal
retrofitting, the energy demands for heating together with
lighting are still the most significant compared to the other
demands.
