According to statistics and official reports, the access to adequate and affordable housing crisis is increasing worldwide, with a significant portion of the crisis related to developing countries. This crisis is exacerbated by environmental degradation and climate change. Consequently, over the past two decades, research has been conducted in various countries to address these crises within the concept of "sustainable affordable housing," the necessity of achieving sustainable affordable housing has been widely accepted among researchers. However, these achievements are not yet fully comprehensive in terms of qualitative and quantitative aspects, and they exhibit considerable ambiguity and dispersion in their results. Moreover, they heavily rely on indigenous contexts and country conditions. In the context of Iran, the experience of the largest subsidized housing project known as "Mehr Housing" and its consequences emphasize the urgency of addressing this issue. This research began with the aim of presenting a conceptual framework model of sustainable affordable housing in the new cities of Iran, which are expanding with government support. The main research question focused on defining the conceptual framework of this housing for Iran, alongside subsidiary questions such as architectural features, obstacles and requirements for realization, optimal models considering indigenous conditions, etc. The research methodology employed a qualitative approach with mixed methods, including content analysis, expert interviews (Delphi method), quantitative data quantification, case studies, and comparative analysis. The first step involved content analysis to identify the components of the conceptual framework, leading to the identification of 59 sub-components. The second step utilized the Delphi method in three rounds to resolve ambiguities in the conceptual framework and reach a consensus among experts. Finally, in the third step, the conceptual framework was developed at two levels: policy and implementation. The findings of the research include the initial conceptual framework at the policy level and its components, such as housing-economy-education and technology planning policies, and the SAH (Sustainable Affordable Housing) implementation-level conceptual framework consisting of 6 components: urban planning, urban design, urban services, housing design, construction methods, and material selection, and technology utilization in building facilities, each comprising 22 sub-components, classified based on priority. Additionally, the SAH architectural model consists of 9 components and associated realization strategies, which not only fully overlap with the sub-components at the implementation level but also have a history of achievement in successful global case studies. The research findings indicate that among the sub-components at the implementation level, certain priorities exist within the framework of sustainable affordable housing in Iran. Finally, an architectural design proposal for a sustainable affordable housing complex, based on the research results, was presented for the assessment of the feasibility of the conceptual framework in the new city of Parand as a case study.
