This article proposes the Evidence-Based Interior Analysis (EBIA) model, an original methodological framework specifically designed for public-use interiors. The model offers a unique integration of Indoor Positioning Systems with user perception surveys within a unified structure. This integration enables the capture of both behavioral patterns and experiential feedback, facilitating their joint analysis for interior design decisions. The model is grounded in three foundational pillars: Spatial behavior studies, evidence-based design, and information and communication technologies. Rather than reporting a specific case study, the article outlines the conceptual and methodological formulation of the EBIA model. It proposes a dynamic, iterative approach that challenges conventional linear design processes and facilitates the development of responsive, user-centered, and sustainable interior environments by aligning spatial configurations with user behavior and long-term functionality. Scalable and applicable across diverse spatial contexts, the EBIA model addresses a critical methodological gap by bridging data-driven analysis with behavior-informed spatial design.eninfo:eu-repo/semantics/openAccessSpatial BehaviorEvidence-Based DesignInformation and Communication Technologies (ICT)Interior EnvironmentMethodological FrameworkArticle10.1177/10717641251396488
