Facade Structures for Energy-efficient Buildings

Abstract

In recent years, there is a growing interest in energy-efficient building all over the world. This paper presents an analysis of the link between the upgrading of the building structures and overall sustainability of a building in the case of facade structures. This research combines such important aspects in design and construction as installation time of façades, energy efficiency and also flexibility of the architectural appearance of a building. The comparative analysis of different facade structures has been conducted in terms of energy efficiency, operation and installation time. The energy efficiency parameters of a facade structure are determined by thermo technical characteristics. The installation and labor costs are analyzed considering factory-assembled panels that are most frequently used in hard-to-reach regions with extreme weather conditions. The additional options for facade structures are also reviewed in the paper, that include microclimate control systems and ventilation facilities. Based on this study, the new type of the façade panel was created. This type of panel combines benefits of the studied facades. The paper presents the description of constructive solutions and thermo technical characteristics.
