In the face of escalating industrialization and climate change, achieving sustainability and promoting its development in contemporary urban environments is paramount. Healthy Buildings, characterized by their prioritization of occupant health, well-being, and minimal environmental impact, are fundamental to constructing sustainable cities. By focusing on strategies that reduce energy and water consumption and align with sustainability principles, Healthy Buildings contributes to thriving and resilient urban environments. Arid cities, particularly vulnerable to the challenges posed by climate change, can benefit significantly from traditional building practices. Traditional Houses in Yazd, renowned for their resilience and health-promoting features, offer valuable examples of climate-resilient design. This research employs a mixed-methods approach, combining qualitative and quantitative methodologies, to investigate the alignment of traditional Yazd houses with contemporary Healthy Building criteria. Key research indicators were identified through content analysis, and their scores and weights were evaluated using the Analytic Hierarchy Process (AHP). By examining these centuries-old resilient structures, this study aims to promote traditional Yazd houses as models for new construction. Findings indicate that a significant proportion of Healthy Building criteria are met by most traditional Yazd houses, positively impacting occupant health and well-being. This research contributes to a deeper understanding of Healthy Buildings in historic urban areas, fostering greater appreciation for these spaces and a deeper understanding of climate resilience over time.
