Evaluation of Energy Renovation Measures for Hospital Buildings using the PSI Method

Abstract

This study investigated the potential for energy savings and reduction in CO2 emissions in hospital buildings in Bosnia and Herzegovina (B&H), through the implementation of energy renovation measures. The building sector in B&H is characterized by significant energy consumption, and hospitals account for a substantial portion of the total energy consumption in public buildings. This study analyzes certain energy renovation measures for selected hospital buildings, including the installation of thermal insulation on exterior walls and flat roofs, and the installation of a photovoltaic plant on the flat roof. The Preference Selection Index (PSI) multicriteria decision-making method was employed to evaluate and rank renovation scenarios based on energy, environmental, and financial criteria. The results indicate that the most preferred measure is the installation of a photovoltaic plant on a flat roof, resulting in significant primary energy and CO2 savings, with an acceptable discounted payback period. The findings emphasize the effectiveness of energy renovation measures in enhancing energy efficiency and reducing the environmental impact of hospital buildings in B&H.
