This image proposes a conceptual 4×4 matrix that relates architectural design dimensions to temporal design strategies. The horizontal axis articulates four design dimensions—Material, Form, Process, and Purpose—while the vertical axis organizes four strategies—Conservation, Durability, Continuity, and Optimization. Each cell identifies representative architectural actions, such as material reuse, structural robustness, digital fabrication, lifecycle management, or adaptive reuse, and links them to corresponding UN Sustainable Development Goals (SDGs). For each strategy, the primary SDGs are listed first, followed by the supporting ones, based on the author's understanding of the SDGs. The matrix is intended as an analytical and pedagogical tool for examining how architectural decisions can be systematically aligned with resource responsibility, long-term viability, and environmental impact. Thereby, it frames sustainable architecture not merely as technical compliance, but as a design culture whose aesthetic quality emerges from deliberate, time-based design thinking—distinct from the extractive logics that have shaped architectural practice since industrial modernism. As this matrix is presented in a provisional form, readers are requested to exercise discretion in citing or referencing the matrix.
