Abstract

BACKGROUND AND OBJECTIVES. Modern university buildings use a large number of resources, such as heat, cold and hot water, as well as electricity, which is the main consumed energy resource and is used for lighting, office equipment, ventilation and air conditioning systems. In order to improve the energy efficiency of university buildings, it is necessary to carry out heat and energy modernization of internal and external envelopes, which will allow for internal billing and qualitative analysis of consumption, which contribute to prompt decision-making on heat and energy modernization of the premises.METHODS. To assess the potential for improving the energy efficiency of buildings by improving the quality of protective structures, methods for assessing the temperature and humidity conditions of multilayered enclosing structures in a wide range of humidity under stationary boundary conditions were developed on the basis of the University Hub of Knowledge.FINDINGS. On the basis of the University Hub of Knowledge, Kyiv National University of Technologies and Design, the moisture content profile was calculated for the general estimation of the moisture condition for building No. 4, the planes of the highest moisture content were determined to find the most dangerous, from the moisture condition point of view, section of the structure, the calculation of the enclosing structure modernization according to the maximum allowable moisture condition for the analysis of moisture accumulation in the coldest month of the year was made.CONCLUSION. The advantage of the proposed method of increasing the energy efficiency of buildings by improving the quality of protective structures based on the University Hub of Knowledge is the possibility of calculation in a wide range of moisture content of materials, including supersorption moisture zone, as well as applicability to structures with multizone condensation of moisture. The clarity and simplicity of the proposed method makes it available for the practical implementation of energy efficiency improvements in all university buildings.

Highlights

The reduction of energy natural reserves acutely puts the problem of energy conservation and energy efficiency of buildings (Di Stefano, 2000)
The absence of modern methods for calculating temperature and moisture conditions in threedimensional areas of enclosing structures, convenient for practical application, makes it difficult to assess the impact of edge zones on the thermal protection and energy efficiency of operating university buildings (Nikolayeva, 2018)
The problem of energy saving and improving the energy efficiency of operating university buildings leads to the need to study the processes of heat and mass transfer and the development of methods for calculating the temperature and humidity conditions of the enclosing structures (On energy saving: Law of Ukraine, 2021)

Summary

Introduction

The reduction of energy natural reserves acutely puts the problem of energy conservation and energy efficiency of buildings (Di Stefano, 2000). The absence of modern methods for calculating temperature and moisture conditions in threedimensional areas of enclosing structures, convenient for practical application, makes it difficult to assess the impact of edge zones on the thermal protection and energy efficiency of operating university buildings (Nikolayeva, 2018). The problem of energy saving and improving the energy efficiency of operating university buildings leads to the need to study the processes of heat and mass transfer and the development of methods for calculating the temperature and humidity conditions of the enclosing structures (On energy saving: Law of Ukraine, 2021). The advantage of the qualitative analysis of consumption, proposed method of increasing the energy which contribute to prompt decision- efficiency of buildings by improving the making on heat and energy modernization quality of protective structures based on of the premises.
