Challenges and Current Research Trends for Vernacular Architecture in a Global World: A Literature Review

Vernacular architecture can be defined as a type of regional construction influenced by geography, available materials, climate, traditions, and culture that is produced by non-experts through knowledge transmitted and enriched from one generation to the next. In addition to their heritage value, traditional buildings are usually considered a model of sustainability in the use of available resources, with a minimal negative environmental impact, minimization of costs, and a reduction of energy demand. In the current context of the globalization of construction techniques and high requirements of comfortable dwellings, the preservation of vernacular architecture means a major challenge, given that this kind of architecture represents more than 75% of the world’s existing buildings. Based on a study of selected peer-reviewed literature indexed in the Web of Science for the period between 2000 and 2022, this paper qualitatively analyzes the current areas of research on vernacular architecture, with particular attention to the scope of the studies, traditional building materials and construction techniques, preservation problems and solutions, climate adaptation, and the reuse of abandoned vernacular buildings. In order to achieve the goal of preserving vernacular architecture in the coming centuries, research should continue in interdisciplinary teams by promoting fieldwork in under-studied regions and incorporating modern materials and solutions in old vernacular buildings to satisfy current comfort standards without excessively changing their essential features.
