At present, in time of sustainable environment, people views are increasingly focused on the energy performance of buildings. In recent years, there has been a huge increase in the rate of insulation of buildings. Thermal insulation of facades and roofs of buildings has been theoretically mastered and practically realized. Recently, we have also encountered thermal insulation of foundation structures to prevent heat leakage through massive concrete foundation structures into the subgrade. As clear from the available materials, the temperature in the foundation area at a depth of 2.0 m to 4.0 m below the ground fluctuates in the range of from 5 to 10 degrees Celsius. To prevent heat transfer from rooms, where it is from 20 to 24 degrees Celsius, a suitable solution to this problem is the use of layered foundation slabs with thermal insulation. Theoretically, from a static point of view, this is a solution of a layered plate placed on a flexible base. The elastic subsoil can be modelled by surface subsoil models, mainly a Winkler or Pasternak subsoil. The layered base plate model was created in ANSYS. The layered element SHELL181 from the library of finite elements was used as the main finite element. In solving a specific problem, the finite element by thickness contains a total of 3 layers of material with a total slab thickness of 700 mm. The plate is resiliently supported by elastic supports modelled by the Winkler model. The plate is loaded with solitary forces representing the reactions from columns of upper building. The results of the computational model can be used for further modelling of selected factors influencing the interaction of the surface foundation and the subsoil. The acquired knowledge will be used for more effective design of layered foundation structures in real conditions, in the natural inhomogeneous environment of the land mass.
