Benchmarking of Heat Energy Consumption in Public Buildings in the City of Kragujevac


Final energy consumption in buildings has the highest share in final energy consumption on a global level. Heat has the highest share in final energy consumption in European buildings. Also, public buildings consume more final energy than residential buildings in general. Specific heat consumption is an important parameter that indicates the state of energy efficiency of the building sector. In this paper, specific heat consumption of public buildings in the city of Kragujevac is analyzed. Part of the data collected for the Energy Efficiency Program for the City of Kragujevac is presented and compared with similar results from other countries and cities. Authors conclude that specific heat consumption in municipal buildings of Kragujevac is relatively high compared to other countries and that its values also vary depending on building purpose and building built year.

    I find your work very interesting. I would like to know more about your point of view about the difference between specific heat consumption in educational buildings in Serbia and other European countries, having in mind that educational buildings represent a very high percentage of all analyzed public buildings. Thank you very much.

      Dear Ivana, thank you for your comment. There are several reasons for unfavorable comparison of specific heat consumption in educational buildings in Serbia and other European countries presented in our paper.

      The majority of analyzed educational buildings in Serbia, as well as other public building, were built in between 1946 – 1980, a period without, or with poor legislation dealing with thermal insulation of public buildings and buildings at all. Besides, until now, almost none of the analyzed educational buildings, except regular maintenance, have passed the process of renovation. Heat losses through heat transmission through thin concrete walls with poor thermal insulation and great window surfaces with double framed single glasses, as well as air infiltration through dilapidated mainly wooden doors and windows, are significant.

      The majority of the greatest consumers of heat are big city schools and kindergartens mainly connected to the district heating system. Educational buildings connected to district heating system do not have the possibility to control heating schedule (no automatic control in substations), so they are heated during non–occupancy periods on the same manner as during occupancy periods as residential buildings.

      Besides, heating bills for educational buildings are paid from the city’s and not from the school’s budgets, according to the heated floor area of the schools, so neither the school administration, neither the city management have had real motives to save energy.

      According to all mentioned, specific heating energy consumption in educational and other public buildings is higher comparing to the buildings of the same purpose in other European countries.
