Although a growing body of research has debated the array of sustainability lessons of vernacular architecture, social sustainability discussions remain less advanced in comparison to the other pillars of sustainability. This has narrowed the plural lessons of vernacular architecture and limited the broad concept of sustainability to a partial one. Against this research gap, this study aims to conduct an assessment of the social sustainability of residential vernacular architecture through the application of a proposed Social Criteria of Green Building Assessment Tool (SCGBAT) assessment method. The SCGBAT proposes eight sets of social criteria categories namely; health and safety; participation and control; education; equity, accessibility and satisfaction; social cohesion; cultural values; physical resilience and also, 37 indicators for the evaluation of social sustainability. To empirically operationalize the proposed SCGBAT, this study utilizes the vernacular architecture typologies in the vernacular landscape of Louroujina village in Cyprus as a case study. Methods for data collection are desk review for secondary data while 135 close-ended questionnaires were used for primary data. The data are statistically presented based on Linkert scale and interpreted using both quantitative and descriptive analysis. The results demonstrated that the investigated vernacular architecture ranked lowly in Physical Resilience Indicator (PRI), Environmental Education Indicator (EEI), Accessibility and Satisfaction Indicator (ASI) but demonstrated sufficient lessons in the context of Health and Safety Indicator (HSI); Participation and Control Indicator (PCI); Social Equity Indicator (SEI); Social Cohesion Indicator (SCI); and Cultural Value Indicator (CVI). To this end, this paper contribute to the advancement of knowledge on the assessment of the social sustainability of vernacular architecture by innovatively applying a green building assessment approach and identifying the strengths and weaknesses of such approach in a vernacular setting.
