Energy benchmarking in educational buildings in the city of Kragujevac - possibilities for energy efficiency improvement

The implementation of energy efficiency measures and use of renewable energy
 sources in educational buildings can significantly contribute to reducing
 energy consumption, but also to CO2 emissions in the entire public sector.
 The paper shows the comparison of energy consumption indicators for 61
 elementary school buildings which have previously been divided in 12 groups,
 according to the period of construction and size, based on the national
 typology called TABULA, as the first step of further study on how to use the
 renewable energy sources. The aim of this paper is to use the energy
 benchmarking process to select representative facilities which are suitable
 for applying renewable energy sources, for their further energy efficiency
 improvement. Indicators of annual specific electricity consumption and CO2
 emissions per unit area [kWh/m2] and per user [kWh/user] were calculated.
 After that, from two groups (in which the highest electricity consumption
 and CO2 emissions are 68.37% and 74.53% of the total consumption/
 emissions), one representative facility was selected.
