This research examines the potential of widespread facade systems to improve energy
performance and enhance user comfort in residential buildings. 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 (ROI), Net present
value (NPV), and Internal rate of return (IRR). The multi-criteria evaluation framework
employed allowed for a comprehensive analysis, balancing technical performance with
economic and qualitative factors to identify the most favorable facade systems. By
addressing both the immediate economic returns and longer-term benefits, this research
contributes to a more sustainable and economically feasible building practice.
