Sustainable architecture has become a very important area of interest, which is focused on energy-efficient design principles and responsible management of environmental resources. The present research makes a comparative study of sustainable architectural buildings in the framework of futures studies and sustainable energy architectural modeling. Its main objective is to test the effectiveness of scenario-based futures studies in comparison with conventional approaches for formulating strategic foresight in sustainable architecture. The findings suggest that methodologies employed in future studies produce outcomes that are both more effective and more representative of real-world applications. This research adopts a mixed-method approach, integrating qualitative and quantitative analyses to evaluate traditional architectural practices against those emerging from future study scenarios. The approach is mixed methodological, in that it integrates wide literature reviews, a SWOT analysis, and the framing of ten scenarios and strategies within the realm of energy-efficient and renewable systems. Graphical modeling highlights these findings, showing the interlinkages between adaptability, innovation, and environmental outcomes. The study provides actionable insights for policymakers, architects, and researchers working to advance sustainable design paradigms. The study reveals methodologies of the futures approach significantly enhance strategic planning and execution in the development of sustainable architectural designs. Scenario-based approaches are more flexible and provide stronger frameworks, aligning better with real-life dynamics and the uncertainties of the future.
