The contribution deals with the energy performance of variants of the building with the glazed cladding. Nowadays, glass facades on commercial buildings are a big fashion hit. Correct adjustment of the glazed surfaces helps us to warm the interior in the cold months, but in the summer months, the interior space becomes overheated. These buildings then look truly original, modern and architecturally interesting. The paper offers possibilities of the structural design of facade shielding and compares the results of energy performance evaluation of the building without shielding, with shielding, with solar collectors and photovoltaic panels. Solar energy is used almost everywhere in the world. The exceptions are the polar region. Solar energy can be converted into heat or electricity. The comparison and evaluation of four variants of the solution from the energy point of view is presented within the paper. It concludes that in a given simulated situation, the best option is a building with solar collectors. It emphasizes, however, that the conclusions cannot be applied across the board. The big advantage compared to the given models is the much lower emission value when using solar collectors compared to other models. This value is up to 70% lower. This is very important environmental and sustainable factor. The issue of sustainable development is receiving increasing attention, and for this reason, the use of fossil fuels should be gradually phased out and replaced by renewable energy sources.
