Abstract
This paper examines the potential for transforming the Faculty of Mechanical Engineering building in Mostar into a Net Zero Energy Building (NZEB). The study assesses the building’s current energy consumption and explores feasible upgrades to achieve complete energy independence and zero CO2 emissions. The hybrid system, composed of rooftop solar panels, wind turbines, and a heat pump, has been thoroughly analyzed in this research to identify opportunities for optimization and expansion. Using software tools such as HOMER Pro and SUNNY DESIGN, the study models renewable energy capacities and simulates system performance to determine the investment potential and economic feasibility of achieving net-zero energy status. The findings offer valuable insights into practical strategies for implementing NZEB principles in public buildings across Bosnia and Herzegovina, contributing to broader sustainability goals and energy security in the region.
