This chapter provides a comprehensive analysis of energy efficiency in buildings, focusing on regulatory requirements, current practices, and the state of energy efficiency in Ukraine and worldwide. It examines the substantial energy consumption in the construction sector and the inefficiencies in Ukraine's housing stock, emphasizing the need for thermal modernization and reduced energy consumption in residential buildings. The impact of European Union energy efficiency standards on construction projects is explored, along with measures implemented in Ukraine for improvement. Key considerations such as the interaction of building elements, air exchange, and development of a mathematical model for thermal conditions and heat losses are highlighted. The significance of optimizing indoor air quality and managing air exchange rates to balance energy savings and occupant comfort is discussed, alongside standards and regulations from the US and the EU. The paper delves into ventilation rates, air exchange requirements, CO2 level measurement, and the use of natural and mechanical ventilation systems. It extends the analysis to estimating infiltration in commercial buildings using various coefficients and considers the importance of hourly climate data and software tools for accurate energy performance assessments. Additionally, the research addresses the health impacts of indoor air pollutants, such as carbon dioxide, bioeffluents, and particulate matter, and underscores the importance of compliance with WHO guidelines and national standards for maintaining healthy indoor environments. Empirical studies on natural ventilation, adaptive comfort, and the effect of pollutants on cognitive performance are reviewed. The paper also incorporates a broad range of sources, offering valuable insights into the optimization of indoor environmental quality and energy efficiency in buildings, with specific focus on thermal comfort, the role of occupant behavior, and methodologies for indoor climate monitoring and energy performance assessment.

It examines the substantial energy consumption in the construction sector and the inefficiencies in Ukraine's housing stock, emphasizing the need for thermal modernization and reduced energy consumption in residential buildings. The impact of European Union energy efficiency standards on construction projects is explored, along with measures implemented in Ukraine for improvement. Key considerations such as the interaction of building elements, air exchange, and development of a mathematical model for thermal conditions and heat losses are highlighted. The significance of optimizing indoor air quality and managing air exchange rates to balance energy savings and occupant comfort is discussed, alongside standards and regulations from the US and the EU. The paper delves into ventilation rates, air exchange requirements, CO2 level measurement, and the use of natural and mechanical ventilation systems. It extends the analysis to estimating infiltration in commercial buildings using various coefficients and considers the importance of hourly climate data and software tools for accurate energy performance assessments.
