Utilizing Design Builder software (Version 5.0.3.7), the study specifically aimed to reduce heating energy consumption, a significant concern in the climatic conditions of Serbia. The methodology incorporated both technical performance assessments and economic analyses, evaluating the economic viability through metrics such as return on investment, Net present value, and internal rate of return. The multi-criteria evaluation framework employed allowed for a comprehensive analysis, balancing technical performance with economic and qualitative factors to identify the most favorable façade systems. By addressing both the immediate economic returns and longer-term benefits, this research contributes to a more sustainable and economically feasible building practice.
