REVIEW OF ENERGY CONSUMPTION AND CO2 EMISSION IN SCHOOL BUILDINGS: CASE STUDY OF THE CITY OF KRAGUJEVAC

Annual energy consumption in Kragujevac elementary schools is 1.909 MWh of electric energy and 12.510 MWh of heat energy, while the total CO2 emission is 6.406 t. This paper provides an overview of energy consumption and CO2 emissions in 61 elementary school buildings, divided in 12 groups. The goal of this paper is to determine which group of school facilities, depending on the year of construction and area, consumes the most energy and produces the most CO2 emissions. It has been shown that most electrical (36,33%) and heat (41,42%) energy are consumed in the school buildings constructed in the period 1971-1990. Most CO2 emissions (40,39%) come from energy consumed in the school buildings constructed in the same period. It is this group of buildings that represents a significant potential for energy savings and reduction of CO2 emissions, through the implementation of various energy efficiency measures.
