The research activity of the department focuses on the design and analysis of architectural structures, theoretical and experimental analysis of low-energy and low-entropy buildings. Significant attention is paid to the evaluation of transparent structures on the basis of qualitative and quantitative. Experimentally, the department pays attention to the study of the interaction of building structures (roofs and facades) with structures with integrated vegetation layer. For research purposes, experimental roof segments of vegetated biodiverse and wetland roofs of variant compositions are constructed in order to measure in situ their influence on building structures and the building as a whole. It also addresses heat and moisture fluxes in building structures and the quantification of the degree of influence of different types of building envelope on the overall energy balance of buildings, as well as the assessment of thermal, moisture and light conditions in buildings. Significant attention is also paid to the diagnosis of physical faults and the restoration of buildings, as well as to the verification of the effectiveness of remediation measures in removing faults.
