#### 3.1.3 The Experimental Family House EB2020  
The synthesis of the knowledge obtained from the scientific analysis was applied by transforming the data into the design, project, implementation, and measurements of the experimental family house EB2020. In [21], we addressed the issue of energy (solar) roofs (ESR) and described the design, implementation, and measurements of the experimental EB2020 family house. Publication [22] focused on the design, implementation, and measurements of a ground heat storage (GHS) on the family house in question. Following on from previous publications, we focus more on active thermal protection in this article. In Section 3.1.1, we described the parametric study and analysis of the energy potential of active thermal protection as a thermal barrier for the perimeter walls of the experimental family house EB2020. The experimental house called EB2020 is in the village of Tomasov, about 25 km from Bratislava. It is a family house with two floors. On the first floor is an entrance hall, living room with a kitchen, bathroom, and guest room. There is a hallway, three bedrooms, and a bathroom on the second floor. Figure 26a,b view the experimental house from the street and the garden. The perimeter walls are made of aerated concrete blocks of 375 mm thickness, layers with active thermal protection of 25 to 30 mm thickness, thermal insulation of 100 mm thickness, and are plastered on the exterior and interior with plaster of 15 mm thickness. Active thermal protection is a dynamic process that, in combined building-energy systems, in structures with integrated energy-active elements, depending on the design and material composition of the building envelope, can serve for heating, cooling, thermal barrier, heat/cooling storage, and other energy functions. The active thermal barrier piping is mainly made of plastic pipes placed between the load-bearing part of the building structure and the thermal insulation in the mortar bed, Figures 18 and 19. The piping on the experimental house EB2020 is fixed with plastic battens, Figure 27.  
In December 2011, the system was put into operation with the use of ATP and under-floor heating (UH), with the temporary use of a low-temperature gas boiler and a hot-water fireplace insert as heat sources. In the 2012/2013 heating season, the heat was also partially supplied to the ATP from the ground source heat storage (GHS). In the summer season, the ATP was operated in the wall cooling function. The source of cooling is plastic pipe circuits located in the ground at a non-freezing depth around the house's foundation.

In Figure 28, we present a simplified principal diagram of the combined building-energy systems of the EB2020 experimental house with peak heat sources. To better illustrate the individual energy systems and the overall technical design of the experimental house, we also provide photographs. The aim of the experimental measurements was a comprehensive evaluation of the system, focusing on the energy and economic aspects, evaluation of the environmental impact, and measurement of the internal environment of the building. The system had to be compared with another operation to draw relevant conclusions. The system was therefore tested in different operations--with and without using ATP. Different inlet temperatures of the working substance to the ATP (thermal barrier) and to the underfloor heating were set to find the optimum energy system use. Comparing different energy system operations in one building is more efficient than measuring different operations in multiple buildings. A single building has the same design and technical boundary conditions, the same number, and occupants' behavior. The first objective of the long-term measurements was to determine whether operating the energy system with active thermal protection in the thermal barrier and wall heating function makes sense.
