CO2 EMISSION OF A nZEB BUSINESS FACILITY IN NIŠ AND ITS IMPACT ON THE ENVIRONMENT

The emission of greenhouse gases, particularly CO2, is widely recognized globally for its significant impact on the climate worldwide. These gases substantially influence the climate across the globe, thereby increasing the demand for greater energy usage and, consequently, elevating the energy requirements for HVAC (Heating, Ventilation, and Air Conditioning) systems. Additionally, the rise in atmospheric CO2 poses a serious threat to human health and ecosystems, presenting an even greater challenge for thermal comfort. Consequently, there is a growing necessity to study buildings in order to achieve Nearly Zero Energy Buildings (nZEB). This specific study aims to demonstrate the influence of energy consumption on CO2 emission in the environment, utilizing energy sources from district heating/cooling and heat pumps, through simulations conducted using EnergyPlus software. The building subjected to these simulations is a multi-purpose structure primarily used for office purposes, located in Niš, Serbia.
