Аннотация: (English) The incorporation of sustainable development concepts into residential projects presents one of the most difficult and significant problems in modern-day construction. The notion that there is an inherent trade-off between sustainability investments and minimizing costs obscures the fact that sustainable development and affordability have complementary relationships during the entire life cycle of buildings. In this article we discuss four areas of the relationship between sustainability and affordability: 1) reconciling sustainability and affordability as two competing objectives; 2) the application of energy efficiency and lifecycle cost methods to produce long term affordability; 3) the production of large-scale housing using sustainable materials and locally sourced raw materials; and 4) how sustainable affordable housing can contribute to achieving the UN's Sustainable Development Goals (SDGs). Through the results of a systematic review of relevant academic literature, the authors position the integrated engineering and management methodology of Chirkin as the operational model for reconciling sustainability and affordability at the project level. Each of the four pillars of the Chirkin methodology - engineering-management integration, turnkey standardization, lean operational logic, and scalable modularity - addresses each of the tensions related to sustainability-affordability discussed within the literature to provide a structural method to produce houses that are both cost effective, energy efficient and aligned with SDGs. Directions for policy implications and potential avenues for future research based on the findings from the study will be presented.
