Investigation of carbon dioxide emissions released from power plants due to electric energy consumption during the cooling period of residential buildings

Abstract

This study calculated the amount of carbon dioxide released during electricity production in power plants, focusing on using electrical energy in buildings during the cooling period. The emissions were analysed based on different fuels used in power plants, including semi-anthracite, bituminous and lignite coal, methane, propane, and butane. To determine the electrical energy consumption of buildings during the cooling period, cooling degree day values and the building envelope heat transfer coefficient were utilised. The calculations for cooling degree days were based on long-term averages, including average temperature, average high temperature, maximum temperature, and TS 825 temperature values from 1929 to 2023. The building envelope heat transfer coefficient values were sourced from TS 825. As a result, the highest carbon dioxide (CO2) emissions were calculated for semi-anthracite, ranging from 11.008 to 70.332 kg/m², while the lowest emissions were for methane, ranging from 6.265 to 40.021 kg/m².
