MODERN APPROACHES TO EVALUATING THE EFFICIENCY OF RESIDENTIAL BUILDING RECONSTRUCTION

Problem statement. This paper reviews methods for assessing the efficiency of residential building reconstruction in Ukraine and Europe. Many existing buildings are outdated or damaged, and their rehabilitation is essential for ensuring safety, energy efficiency, and improved living conditions. In Ukraine, a large portion of the housing stock no longer meets modern standards of comfort, energy efficiency, or safety – an issue intensified by damages resulting from the aggression of the Russian Federation. Traditional assessment methods tend to focus solely on economic factors, such as investment costs and operational savings, while often overlooking the social and environmental impacts of reconstruction. This narrow focus can lead to outcomes that fail to improve overall urban living conditions. By integrating economic, social, and environmental criteria, the study provides a balanced evaluation framework that supports sustainable urban development. The purpose of the study. The objective of this study is to review various methodologies for evaluating the efficiency of residential building reconstruction. The research expands the concept of reconstruction to include renovation, retrofit, and refurbishment measures. It emphasizes the role of modern monitoring technologies, such as Internet of Things (IoT) devices, which provide real-time data on factors like noise, vibration, and air quality. Such an approach enables timely adjustments that reduce negative effects on residents and the environment, ensuring that reconstruction projects are both economically sound and socially responsible. Conclusions. The findings demonstrate that a comprehensive evaluation framework − one that integrates economic, social, and environmental aspects −is essential for effective residential building reconstruction. By balancing cost efficiency with improvements in quality of life and ecological protection, reconstruction projects can significantly enhance urban resilience and sustainability. This holistic approach ultimately contributes to safer, healthier, and more vibrant urban communities.
