This thesis presents modification of the original plan for the decorative facade of the Elos building, which was proposed by the investor. In two introductory chapters, a review of the methodology in the general selection of lightweight construction criteria and the project task in particular is given. After that, the goal of the project was defined using the technical evaluation with the AHP method, and a comparison of different criteria of lightweight construction in general terms, but also specifically for the project, was made. Then, the calculation for the variable load of the substructure was performed by the method of initial parameters for both observed cases, which determined that the original design was oversized, after which a new dimensioning and selection of beams was performed. The problem of constant load was previously solved by constructive design. This was followed by evaluation from the aspect of different materials, analysis and technologies of sheet metal forming. Finally, the real process of execution of the construction is presented, while the conclusion of the thesis shows explanations and calculation of the savings in regards to the mass of the construction by comparing the two observed cases, and thus the savings in financial terms.
