It aims to determine the variance between courtyards design built in traditional, colonial and contemporary periods using a typological approach that considers the urban-morphology, socio-cultural and environmental economics criteria in a chronological context. A comparative analysis of the analysis indicators of each criterion was used to reveal the difference between courtyards and whether there were common design indicators. The results show a clear difference between courtyards in the urban morphological indicators and their effects on the socio-cultural and environmental-economics aspects. In addition, the traditional courtyard can be considered the most successful sustainable design strategy designed with careful attention to socio-cultural and environmental economics contextsenComparative analysis ; Courtyard ; Environmental economics ; Socio-cultural ; Typological approach ; Urban morphologyArticle
