| Summary: | The purpose of the research is to study and systematize the solutions of facade structures for prefabricated and precast-monolithic construction. The article considers single-layer, two-layer and three-layer external wall panels. An analysis of design solutions was carried out in terms of ensuring energy efficiency requirements. Possible options for finishing buildings with external walls made of large-sized elements were analyzed, taking into account their design solutions. The scientific novelty of the article lies in considering the issue of facade decoration both from the point of view of architectural expressiveness and energy efficiency. It also compares the most common types of external wall panels based on the thermal characteristics and geometric dimensions of the materials used and, as a result, their economic feasibility. As a result of the analysis, it can be concluded that modern solutions for prefabricated external walls have great importance for the implementation of design solutions and finishing the facade of buildings from large-size prefabricated elements. The best indicators of all the options considered are the two-layer hinged and three-layer external wall panels.
