AI Integration Framework for Sustainable Architecture: Optimized Pathways

Abstract

The built environment accounts for 30% of global energy consumption and 26% of CO2 emissions, yet AI adoption in sustainable architecture remains fragmented despite transformative potential. This study addresses the critical gap between AI's technological capabilities and practical implementation by developing empirically-validated integration frameworks. Employing convergent parallel mixed-methods, we synthesized 133 publications (2018-2024), examined two case studies, and surveyed 61 industry professionals across six sectors to map adoption patterns, barriers, and opportunities. While AI demonstrates substantial sustainability improvements—up to 70% energy reduction and 65% CO2 emission cuts in optimized buildings—adoption remains concentrated in performance simulation and design optimization, with high-impact applications like generative design significantly underutilized. Primary impediments include skill gaps and workflow integration challenges, despite widespread recognition of AI's benefits. This research contributes three novel elements: (1) a validated three-pillar implementation framework emphasizing human-AI synergy through targeted education, phased integration, and ethical governance; (2) quantitative evidence that skill development explains 62% of adoption variance (R² = 0.62, p < 0.001); and (3) a Sustainability Impact Index (SII) providing standardized assessment metrics. The framework could accelerate industry adoption by 5-7 years, achieving 2.87× improvement in sustainability performance metrics.
