Vernacular architecture takes advantage of environmental and climatic contexts to provide thermal comfort. In response to many microclimate issues, vernacular architecture has found solutions for basic human needs in residential buildings
over decades. Vernacular architecture relied on locally available resources considering socio-economic factors, without relying
on theories and skills gained from formal architectural education. A renewed interest in vernacular architecture has sparked in
recent years because vernacular architecture can achieve thermal comfort with simple techniques. The Egyptian architect, Hassan Fathy, laid the foundations of vernacular language. In this paper, three projects of Fathy in Egypt and Jordan in the post
war period were analyzed to identify the vernacular language.
