The thesis deals with the various stages of using ekopanel. It also shows the other suitable materials intended for construction in this system, which the company Ekopanely proves the functionality. I present the project of the family house using the ekopanels ( the investor is Mr. Žďárky . The original building permit is revised in a Sema software. There is 3 D output created for investor with the workshop documentation required for implementation. The important details are processed in software Autocad and are included in the documentation necessary for the the building itself. The two budgets are calculated. One shows the costs realized by supplier company ( Ekopanely servis s.r.o.) and the other shows the cost of doing yourself (means to build up by the investor) This difference clearly defines the level of cost savings .
