Purpose: The purpose of this study is to consolidate contemporary methodological approaches to assessing energy consumption in residential construction, with a focus on the methodology based on the building life cycle concept. This approach enables a more accurate evaluation of energy consumption impacts at various stages of a building’s existence and facilitates the development of recommendations for improving energy efficiency.
Design/methodology/approach: The study employs a comprehensive approach to energy consumption assessment, covering all stages of the residential building life cycle: design, construction, operation, demolition, and disposal. Special attention is given to the differentiation between embodied and operational energy. The research applies methods of energy auditing, energy balance, exergy analysis, and life cycle cost analysis.
Practical implications: The research findings can be used as a tool for planning and monitoring the energy efficiency of residential buildings. They hold practical value for designers, developers, energy auditors, and regulatory authorities in the development of strategies to reduce energy consumption and carbon emissions, especially in the context of the post-war reconstruction of Ukraine’s housing stock.
Originality/value: The originality of the study lies in the integration of energy consumption assessment approaches within the framework of the full building life cycle. This allows not only for the quantitative determination of energy expenditures but also for their strategic optimization over time.
