The awareness of the vulnerability of existing structures under both seismic and energy perspectives highlights the need for integrated retrofit solutions that combine structural and thermal enhancements. From this perspective, this study explored the efficacy of the Resisto 5.9 Tube system, which is a seismic retrofit solution for masonry and reinforced concrete (RC) structures that also improves the energy performance by integrating a thermal coat integrated within its basic steel framework. This research involved application to a RC building of a design procedure specifically developed for this system that was aimed at facilitating its adoption by designers involved in seismic retrofitting analysis. After designing the system components, nonlinear static analyses were performed using finite element software to compare the building’s seismic performance before and after the application of the Resisto 5.9 Tube. The results demonstrate a significant increase in the seismic safety coefficient ζE from 0.26 to 0.42, which proved the potential of this intervention to enhance the seismic safety of existing RC buildings.

Energy-efficient, adaptive, affordable and durable curtain wall systems have always attracted great interest among the scientific and technical communities. In this regard, the purpose of this work was to conduct a comprehensive review of the issues related to energy-efficient adaptive dynamic facades, taking into account their operating loads, revealing the diversity of the studies conducted in this area. The review of the literature was carried out in three stages. For all stages, the review period was 2001–2024. In the first stage, a review of traditional curtain facade systems was conducted, which emphasized the relevance of this area, identifying a total of 4338 sources. In the second stage, a review of specific issues, such as adaptive dynamic facade systems, yielded 2838 sources, from which the 87 most suitable sources were selected. In the third stage, a review focusing on the issue of operating loads yielded 741 works, from which 43 suitable sources were selected. At the same time, pie charts reflecting the most active international scientific journals were compiled for each area. The conducted review of energy-efficient adaptive dynamic building facades, taking into account their operating loads, could provide significant assistance in further research on the specified issues. As researchers mainly focus on environmental friendliness and cost-effectiveness, they often neglect issues such as the systems’ resistance to operating loads, which represents a serious deficiency. In this regard, this review identified a gap in the research on the development of energy-efficient facades with an air layer; on this basis, the further development of adaptive facade systems is required. The review of the selected studies also showed that issues related to energy efficiency and sustainability, taking into account operational loads, have not been addressed in combination; rather, they have only been addressed individually. At the same time, this review shows that the proposed development of an adaptive system of external fencing could be relevant, both nationally and internationally, depending on the natural and climatic conditions of the territory for which the buildings are designed.
Post-industrial sites are a part of many cities. The impacts of industrial activities are not only evident in the area where the activity took place, but also affect the buildings within these areas. Buildings that served the industry in the past were built mainly by mass construction methods. From today’s point of view, these buildings are unsatisfactory in terms of typology, operation, and energy. In particular, energy rehabilitation is a way to restore industrial buildings and bring them to a full-fledged state. This issue is documented in a case study of a city affected by underground mining activity and on a selected skeleton construction. Given that industrial buildings have heavy or mass structures where some elements like beams and columns are damaged, it is crucial to consider not only energy solutions, but also the structural and architectural aspects of these buildings. In terms of thermal engineering and energy, including the renovation of structures, a software-supported evaluation of three material variants for the envelope walls of the skeleton construction from the 1970s was conducted. This study evaluates the thermal performance of conventional, proposed, and traditional wall designs by analysing their U-values, thermal resistance, and structural advantages. The results reveal that the conventional wall, featuring a 150 mm EPS 70 NEO insulation layer, achieves the lowest U-value, outperforming the proposed wall by a factor of 1.2 in thermal resistance. Both designs significantly reduce U-values compared to traditional walls, by factors of 6.55 and 5.40, respectively. Despite a 23% reduction in thickness relative to the conventional wall (and 44% compared to traditional walls), the proposed wall demonstrates robust thermal performance. Further benefits include reduced structural dead load, with the conventional and proposed walls being 3.70 times lighter per square meter than traditional walls. This reduction can decrease foundation, column, and beam dimensions, optimizing building design. Thermal bridging analysis highlights superior corner insulation in conventional walls due to higher surface temperatures, while the proposed wall maintains effective insulation with surface temperatures close to indoor conditions. Overall, the findings underscore the importance of advanced materials in achieving efficient thermal performance while balancing architectural and structural demands. The results achieved from the experimental work show that industrial buildings can be effectively energy-renovated in a way that complies with legislative documents, successfully extends the physical life of the frame structures, and contributes to carbon neutrality.
