Analysis of potential energy retrofit measures for an existing educational building

Abstract

This paper analyzes energy retrofit measures for a preschool facility in the city of Kragujevac, with the aim of improving the building’s energy efficiency and achieving significant energy savings, while simultaneously meeting all necessary requirements specific to such institutions. Various approaches were studied, including the application of thermal insulation, replacement of exterior windows and doors, installation of underfloor heating systems, as well as the integration of ventilation systems with and without heat recovery. Finally, the installation of a solar photovoltaic system as a renewable energy source was considered, in order to meet the electricity consumption needs for the operation of the previously mentioned systems and further increase the building’s energy efficiency. Simulations conducted using the EnergyPlus software demonstrated a significant reduction in heating and cooling energy consumption, even with the implementation of ventilation systems.
