## 3 Results and Discussion in General  
### Results  
In general, the results of our long-term research can be divided into theoretical (mathematical-physical models, computer simulations, parametric studies) and practical (a collection of different functional schemes for the connection of combined building-energy systems in various modes of operation, the creation of prototypes of panels with integrated energy-active elements, the design and implementation of experimental buildings, the implementation and evaluation of experimental measurements, utility models, and patent). In this section, we describe:  
* Parametric study and analysis of the energy potential of active thermal protection in the function of thermal barrier;
* The prototype of the prefabricated house IDA I;
* The Experimental Family House EB2020.  
1.1 Parametric Study and Analysis of the Energy Potential of Active Thermal Protection in the Function of Thermal Barrier  
Figures 18 and 19 show the mathematical-physical models on which we performed a parametric study of active thermal protection as a function of a thermal barrier for a perimeter wall made of aerated concrete blocks. In the design, we investigated the temperature waveforms during the heating period, Figure 18, and during the summer period when cooling is required, Figure 19. The mathematical-physical models show the isotherms for different mean temperatures of the heat transfer medium in the thermal barrier. For example, during the heating season, in Figure 18, the temperature in the structure at the interface between the load-bearing and thermal insulation layers without applying a thermal barrier is \(\theta_{\text{TB}}=1.86\)\({}^{\circ}\)C, with thermal insulation thickness of 100 mm. The application of the thermal barrier modifies the temperature in this layer. For example, a mean temperature of the heat transfer medium of \(\theta_{\text{TB}}=10\)\({}^{\circ}\)C represents an energy saving of 45%, which is the temperature attributable to the structure when thermal insulation of 300 mm thickness is used. Increasing the temperature of the heat transfer fluid in TB also increases the value of  
Both figures show the potential for energy savings and heat/cool accumulation when applying a thermal barrier to the perimeter wall structure in question. For heating, this is an important question.

isotherm of +20 \({}^{\circ}\)C; for cooling, this is an isotherm of +26 \({}^{\circ}\)C. The parametric study results for heating and cooling are given in Tables 1 and 2. The values of the thermal resistance R, the structure U's heat transfer coefficient, and the structure's temperature between the statically load-bearing part of the wall and the thermal insulation layer \(\theta_{\text{TB}}\) for different thicknesses of thermal insulation are given. Values for the wall without TB are shown in gray, and values for the alternative with a mean temperature of the heat transfer medium in the TB of +10 \({}^{\circ}\)C for heating and +28.58 \({}^{\circ}\)C for cooling are shown in green. They represent the equivalent thermal resistance of the building structure with thermal insulation of 300 mm.
