Techno-Economic Analysis of Energy Efficiency Improvements Using Renewable Energy Sources

Abstract

In recent years, the need for renewable energy technologies is growing as a consequence of negative climate changes caused by harmful emissions. Bosnia and Herzegovina, similarly to the rest of the world is committed to follow the trend of reducing greenhouse gas emissions by abandoning electricity production using conventional conversion technologies and renewable energy sources. Traditionally, educational institution facilities have poor energy performance of buildings and energy-inefficient devices. The aim of this paper is to present a techno-economic analysis of a hybrid system based on renewable energy sources for the needs of energy coverage of such an institution in Mostar. The system is designed for the building of the Faculty of Mechanical Engineering in order to improve its energy efficiency. The model is constructed using realistic measurements performed at the facility. In particular, a grid-connected PV system technology and a ground source heat pump were used. Carbon dioxide emission reductions were calculated compared to the classic conventional heating and electricity production system. Results demonstrate that the proposed system can be used in order to improve the energy efficiency of the building.
