ENERGY ANALYSIS OF SERBIAN BUILDING WITH PV PANELS AND DIFFERENT HEATING SYSTEMS

Abstract

Buildings consume a significant part of energy and they are responsible for large emissions of harmful gases, primarily CO2. The largest building energy consumer is the heating system, so it is necessary to investigate all aspects of energy consumption to minimize the total final and primary energy consumption. To reduce energy consumption, it is very important to apply principles for improving energy efficiency. One of the most acceptable solutions is the installation of renewable energy technologies. This paper simulates the operation of the PV system, which can generate a significant amount of electricity and cover part or all of the building energy consumption. Simulation in EnergyPlus software was provided for buildings with three different heating systems - electric heating, district heating, and gas heating. The paper shows annual total final and primary energy consumption, energy savings and possibilities for the generation of a larger amount of electricity, by installing PV panels with higher cell efficiency, in order to minimize building energy consumption.
