The relevance of increasing the energy efficiency in buildings of domestic higher educational institutions is determined not only by the need to save energy resources, but also by the fact that such “green campuses” can become the basis for the formation of an ecological and energy efficient lifestyle for today's youth. An integrated approach to the selection of energy-saving measures in a building requires the models of thermal comfort which take into account the intensity of human activity, the type of clothing, the speed of air movement in the room, relative humidity and the like.
The purpose of this study is to improve the efficiency of the energy system of campus buildings by taking into account the interaction of energy sources, the heating system, the thermal properties of the enclosing structures and the standardized parameters of the indoor microclimate.
Along with an integrated approach to the problem under study, taking into account the necessary comprehensive analysis of energy-saving measures in the system "heat source - enclosing structures - external parameters", attention should be paid to the indoor climate and the problem of meeting human needs for thermal comfort.
With the help of a miniature temperature datalogger RC-1B, a round-the-clock monitoring of temperatures was carried out in some rooms of the educational building No. 8 of National University of Life and Environmental Sciences of Ukraine during the heating season.
The analysis of the experimental data shows that despite the improvement of the thermal accumulative properties of the outer fencing of the building after the implementation of thermal modernization work, the temperatures in the room do not always correspond to the norm.
Thus, when implementing energy-saving measures, it is impossible to violate the conditions of comfort in rooms in which thermal equilibrium is maintained in the human body and there is no tension in its thermoregulation system.
Key words: energy efficiency of the building, multifactor mathematical model, thermal comfort
