On December 8, 2023, students of the 3rd and 4th years of the SE IEE studying under the SPP "Energy Management and Energy Efficient Technologies" visited the laboratory of the Department of Building Physics and Energy Efficiency of the State Enterprise "Research Institute of Building Structures", with which KPI has a cooperation agreement. SE NDIBK not only has modern equipment for researching the properties of building materials and structures, but also takes a leading role in Ukraine in creating national standards, implementing energy efficiency programs in the building stock, and applying energy efficient technologies in construction. In addition, SE NDIBK develops typical projects of thermal modernization of mass-produced buildings in Ukraine, as well as executed unique projects for the restoration of buildings damaged as a result of the military aggression of the Russian Federation.
The class on the topic "Investigation of thermophysical and acoustic properties of enclosing structures" for students of groups ОН-01 and ОНп11 was held as part of the study of the discipline "Energy efficiency and energy certification of buildings". Such classes have been held for energy management students on a regular basis for many years in a row. Acting Head of the Department of Building Physics and Energy Efficiency Andrii Mykhailovych Postolenko and junior researcher of the department Dmytro Vyacheslavovich Bida conducted the classes.
A. M. Postolenko introduced modern technologies in construction and research methods of building and thermal insulation materials. The specialist explained how for standard structural elements (a wall with a balcony block) studies of resistance to climatic influences and deformations are carried out, resistance to wind load is determined and other thermal characteristics are determined. He showed laboratory stands where such characteristics of materials as heat transfer resistance, frost resistance, steam, water, air permeability, etc. are determined. The students were particularly interested in a special chamber where efficient operation is predicted: the structure or material is exposed to radiation as an imitation of solar insolation, humidification as an imitation of rain, freezing to -30°C and heating to +60°C as an imitation of the external environment for 60 cycles.
D.V. Bida talked about special cameras for studying the acoustic properties of structures and assessing the influence of external and internal noise sources. The students got acquainted with the means of soundproofing, sound absorption, and also visited an anechoic chamber, where there is practically no sound reflection.
Such classes improve the interest of students, the perception of the material and the level of future specialists. Such scientific experiments can also be carried out within the framework of master's theses, which increases the level of research works of the university.
