Energy Efficiency Management of Residential Buildings in the Context of Sustainable Development

Abstract

Abstract: Purpose: This study aims to investigate the use of secondary energy sources in the residential sector of Ukraine from the perspective of energy management, considering their role as a tool to enhance energy efficiency, energy savings, and the resilience of buildings while supporting sustainable development. Methods: The research involves systematization and analysis of the main types of secondary energy sources, including heat from ventilation exhaust, wastewater, spent air, and surplus heat from engineering systems. Managerial decisions regarding the selection, integration, and operation of heat recovery ventilation systems, wastewater heat recovery technologies, and surplus heat utilization are examined. The study also considers building life cycle stages, thermal modernization, and municipal-level planning and control. Results: The findings demonstrate that effective management of secondary energy sources maximizes energy and economic benefits, especially when combined with insulation measures, modern HVAC systems, and heat pumps throughout all stages of a building’s life cycle. Secondary energy use reduces primary energy consumption, lowers household energy costs, and enhances the energy resilience of residential buildings. The study confirms alignment with key Sustainable Development Goals, emphasizing the contribution of secondary energy to green building and sustainable urban management. Conclusions: Integrated energy management of secondary energy sources is a strategic approach for improving energy efficiency, reducing dependence on primary energy, and supporting sustainable development in the Ukrainian residential sector. Successful implementation requires state and municipal support, energy management programs, and incorporation into post-war reconstruction strategies.
