The purpose of the work is to study of options for thermal modernization of enclosing structures with a justification of the optimal composition of energy-saving measures to achieve maximum energy efficiency of buildings. Ukraine's energy balance shows that more than 30% of the total energy is consumed by the residential sector, of which up to 80% goes to heating. This is due to the low level of energy efficiency of the enclosing structures of residential buildings, as well as the unsatisfactory technical condition of utilities, due to physical wear and tear and obsolescence. The peculiarities of the influence of the type of thermal insulation materials and their characteristics on the thermal and energy performance of the building are investigated. It was found that the increase in the density of insulation affects the thermal resistance of walls in different ways - the density of mineral wool and extruded polystyrene have the opposite effect of foamed polystyrene, ie insulation of mineral wool or extruded polystyrene should be chosen with the lowest density Element-by-element analysis of the components of enclosing structures proved that their impact differs significantly, in the case of separate implementation of measures can reduce heat consumption by 0.07… 23%, and the priority is to modernize the walls of building facades (provided that the glazing ratio K ≤ 0 , 25). Measures of complex thermal modernization of enclosing structures are substantiated by the method of expert assessments according to technical-energy, financial and ecological criteria. Calculations confirm that the complex thermal modernization will reduce the value of specific energy consumption and specific greenhouse gas emissions by 1.5 times, specific heat consumption - by 1.9 times, increase the energy efficiency class of the building from G to D. It is shown that the normative values of heat transfer resistances of external enclosing structures will provide only the class D energy efficiency of the building. It is not possible to achieve the recommended class "C" and higher by further increasing the thermal resistance of the enclosing structures - it is necessary to modernize the engineering systems of the building.

The article is devoted to the process of correction (improvement) of a person's psycho-emotional state by creating an electronic device that emits multicolored light effects. The set of researches carried out in the work represents the solved problems in the field of creation of electronic devices for medical purposes. On the basis of the analysis of existing devices, an own design of an electronic device is proposed, based on the emission of various light effects, which allows you to correct the psychoemotional state of a person. A working model of an electronic device has been manufactured, it emits multi-colored light effects, and also measures the main parameters of the environment - temperature, humidity and pressure. Experimental clinical studies of the manufactured device were conducted in the hospital of the Regional Clinical Psychiatric Hospital of the Kirovohrad Regional Council. Experimental clinical studies of the manufactured device were performed by taking encephalograms of the brain. Obtained positive results, confirming the ability of this device to improve the psycho-emotional state of a person.

The article is devoted to the study of improving the efficiency of the electric network with a voltage of 110-150 kV through the use of a developed device FKZ, which uses a radio channel to transmit information. At the present stage of development of electric power industry the question of reliability of work of high-voltage electric networks plays an important role. During the operation of such electrical networks, emergencies inevitably occur, the most dangerous of which are short circuits. Determining the location of damage to the electrical network is the most complex, time-consuming and time-consuming technological operation with significant costs. Therefore, the task of improving the design of devices to determine the location of damage, the use of which will significantly reduce the level of operating costs for electrical networks, is relevant. One of the ways to solve the problem of improving the accuracy of determining the location of a short circuit in the electrical network is the use of special technical means - short circuit clamps. The scheme of the normal regime of the 150 kV electric network of PJSC Kirovogradoblenergo was used for the research. The analysis of the configuration of this network showed that it has a number of substations that receive power from transmission lines, which are deaf branches. Therefore, the installation of short-circuit latches on such lines is necessary. The authors of the article propose the introduction of a radio channel to transmit information about the state of the network and the place of damage to the next personnel of the substation. The most appropriate ways to organize a radio channel are: the use of GSM networks; use of unlicensed frequency transmitters. Approximate calculations have been carried out, which confirm the possibility of creating a radio channel for transmitting information from the short-circuit lock for a distance of up to 20 km, using transceivers of non-licensed frequencies.
