THE CURRENT STATE OF THE RESEARCH ON BUILDING FAÇADE DURABILITY UNDER THE EFFECTS OF CLIMATE CHANGE

Climate change refers to the long-term alteration of the Earth's climate system, typically characterized by changes in global temperature, precipitation patterns, sea levels, and weather events. This changing climate is expected to have a significant impact on the built environment, particularly on the durability of buildings. The question of how the performance of buildings will be within these changing environmental conditions in the future arises in relation. This subject is a complex issue that requires consideration of various building materials, elements and systems, and climate components that are expected to change in a particular region. Accordingly, there have been numerous studies on building durability under the effects of climate change, covering these fields. In these respects, this study aims to provide an overview of the current state of research on building durability under the effects of climate change. The methodology of the study is based on a systematic literature review through two widely used databases (Scopus and Web of Science). In the paper, a brief theoretical background has been provided for climate change and then, the method of the study has been explained in detail. The data obtained from the literature has then been analyzed and discussed concerning the building sub-systems, materials investigated, and the expected change in their performance, climate components, climate projection models, and regions considered. According to the results of the analysis, the building elements system has been the most commonly studied building sub-system, in comparison to the structural and services system, while the façade has been the most studied component under the building elements system. Among the facade materials investigated (concrete, brick, stone, metal, GRSW, waterproofing membranes, porous materials, and retro-reflective materials), wood has been the most frequently studied. Most importantly, it is estimated in the studies that, in regions where temperature and precipitation are expected to increase, the service life of components made of wood will reduce due to decay and mold, and in the case of components made of concrete, brick, stone, and porous materials due to corrosion, carbonation, and salt crystallization.
