## 4 Discussion  
The scientific work shows that the tasks of efficient energy consumption of buildings and structures have remained key for many decades. Therefore, the efforts of the world's leading engineering centers (ASHRAE, ISO, ABOK, etc.) are aimed at developing and modernizing codes for energy-efficient buildings. An energy research (energy modeling) tool is a model of the thermal regime of buildings and structures, which allows for a feasibility study of an energy management system following ISO 50001:2018 \"Energy management systems--Requirements with guidance for use\" [47]. The thermal model of the building must ensure maximum accuracy of calculations. Among the factors influencing the adequacy of the model, the following can be identified: detailing of the models of enclosing structures, properties of all materials that are given in the nodal solution, and weather conditions--the influence of temperature loads depending on the time of year, etc. The constructed thermal model takes into account the specifics of the building associated with features of possible heat gains and heat losses, as well as features of heat exchange of internal and external surfaces of enclosing structures with air through a heat-conducting inclusion. The program stipulates that the model is based on the heat balance equation of the room, which takes into account all possible heat losses and heat gains, subject to the boundary conditions. The parameters of thermal processes are set according to the reference and regulatory literature. These include the heat capacity of walls and ceilings, the heat transfer coefficients of enclosing structures, and the relationship of characteristics with outside air temperature. The results of the simulation modeling of the thermal regime of buildings with alternating ambient temperatures show that the distribution of heat flows inside the balcony floor slab is influenced by the following factors: temperature, the distance of the laid insulation from the outer wall, the insulation of the surface of the floor slab from above and below, the physical and mechanical properties of the insulation, and its thickness. Based on heat flow modeling, a structural and technological solution for the junction of the balcony slab to the outer wall has been developed. This ensures optimal insulation areas of the horizontal surface of the slab.  
Thus, presented study gives two novel scientific results. First is substantiated constructive and technological solutions for insulating complex-shaped facade elements during the design stage. This result is practically oriented, improves current normative document and has technical novelty. The second results is novel experimental statistical model of facade insulation duration allows numerical management of technological and organizational regimes of this works in changing economic and commercial environment.  
The above study made it possible to reduce the insulation area of all balconies and terraces by 50%, which affected the total volume of insulation of the entire building while maintaining the building's energy efficiency indicators.  
In turn, with the help of experimental statistical modeling of organizational and technological solutions for facade thermal insulation, the calculation of the minimum terms for insulating the facade of the building under study was carried out.  
The research results were implemented during the thermal modernization of both the building under study, built using a frame-stone scheme, and buildings created using a frame-monolithic scheme in Odesa, Ukraine (Figure 9).  
In the future, at ambient temperatures favorable for thermal imaging control, observations will be carried out to confirm the correctness of the adopted design and technological solutions. At the moment, there have been no critical comments from management companies or building residents.
