Modern cities are trying to actively reduce energy consumption and carbon emissions during construction, directing their efforts towards achieving sustainable environmental balance. The issue of thermal comfort is becoming increasingly important in the global context, especially in the context of a rapid reduction in energy consumption. The purpose of this study is to assess the level of thermal comfort for the most sensitive segments of the population, in particular preschool children, during the transition and summer periods of the year. Using computer modeling, we determined the energy demand for cooling and additional heating during the transition period at different levels of thermal protection of buildings and different coefficients of clothing resistance. The results of the study confirm that improving the thermal protection of buildings and optimizing temperature control systems, taking into account the thermal resistance of clothing, will maintain the level of thermal comfort, measured by the PMV indicator, within the recommended range of -0.5...+0.5. This will help create comfortable conditions for the most sensitive segments of the population. However, it is important to note that such improvements are accompanied by an increase in energy consumption for heating during the transition period at 11.5% of total energy costs. Thus, these results emphasize the need for a balanced approach to ensuring thermal comfort and optimizing energy consumption in buildings for the most sensitive segments of the population.
Key words: energy saving; comfort conditions, PMV, dynamic building modeling, clothing resistance coefficient
