Due to the increasing pressure brought by recent global environmental problems, building designers are embracing regionalism and the knowledge of traditional structures, arguing that these structures are energy efficient and highly sustainable. We observe clear evidence of the increasing interest in vernacular architecture among the research community. This study therefore aims to clarify the contents and issues raised in the studies on vernacular architecture and the knowledge and recommendations that can be derived from them. A database of the research is established by collecting many studies from primary sources. Obtained data is carefully refined and categorized into a table where synthesized information is introduced. The results of this study show an uneven geographic and climatic distribution of the studies; the trend in selecting research objectives and research objects; the choice of research methods with a clear shift towards quantitative research methods, and the generic findings from the database of the research. These results can support diverse inquiries about vernacular architecture across the world and be used as a resource or an orientation to support numerous subsequent studies.
