The lyceum building is a socially important community facility that is visited daily by students and employees of the institution. Due to the insufficient level of thermal insulation, a significant part of the thermal energy is lost, which leads to increased heating costs and creates uncomfortable conditions for learning in the autumn-winter period. The implementation of the project to insulate the lyceum building is aimed at increasing the energy efficiency of the building, reducing energy consumption and rational use of budget funds. Insulating the facade, roof and foundation of the building will allow stabilizing the temperature regime in educational premises, which will positively affect the health of students, the level of their attendance and the quality of the educational process. Installing airtight entrance doors will lead to a reduction in heat loss. The project has a pronounced social and environmental component, as it will contribute to the creation of a safe, comfortable and modern educational environment, as well as reducing greenhouse gas emissions by reducing heat energy consumption. The resulting effect will be long-term and will persist for many years after the project is completed.

The need to create comfortable conditions for students and staff in all premises of the facility. According to temperature indicators inside the facility, the Zhyrychiv Lyceum, during the period of operation of the institution, has an average temperature of 16.7 °C, which is below the permissible standards and is almost 2 °C lower than in other educational institutions where energy modernization has already been carried out. A feature of the Zhyrychiv Lyceum building is that in some rooms the internal temperature exceeds 21 °C, and in some rooms it is 13 °C, and as a result the average temperature is balanced to 16.7 °C by warm and cold rooms. Extremely uncomfortable conditions for staying in the lyceum arise at significantly low outdoor temperatures, which leads to the non-use of some educational premises of the building at all. The introduction of additional energy-efficient measures will allow balancing the internal temperature in the premises and creating comfortable conditions for staying in its students and staff in general. The possibility of obtaining significant indicators of energy consumption savings and CO2 emissions reduction at the facility. According to the calculations made on the preliminary assessment of the reduction of energy costs and CO2 emissions, the implementation of the necessary energy-efficient measures will allow reducing energy consumption by at least 30%, reducing the negative impact on the environment and saving local budget funds, which is very relevant in the context of constantly increasing energy prices. A significant part of the budget is spent on paying for energy without the proper effect. After thermal modernization, a decrease in thermal energy consumption is expected, which will allow optimizing costs and directing funds to the development of the lyceum. Constant temperature changes accelerate the destruction of facades and ceilings. Thermal modernization will protect structures from the negative impact of external factors and extend the life of the building. The implementation of the thermal modernization project of the lyceum premises will allow comprehensively solving existing problems, ensuring comfortable learning conditions, reducing energy costs and contributing to the sustainable development of the educational institution.
