Abstract: This study presents the comprehensive analysis of Indoor Environmental Quality (IEQ) in a research complex, addressing a gap in existing literature. Employing an innovative location-based survey system with GIS integration and 3D visualization capabilities, we analyzed IEQ factors across 16 buildings in a research complex through 275 occupant responses. Multiple regression analysis revealed that office layout was the primary factor influencing overall comfort (45.86%), followed by acoustic quality (26.87%), thermal comfort (22.00%), air quality (20.33%), and lighting (13.00%). The analysis also demonstrated a strong correlation between overall comfort and productivity (R² = 0.7668). Building-specific analyses showed varying patterns of IEQ influence, highlighting the need for tailored environmental strategies. Our novel approach to data collection and visualization enables precise spatial mapping of environmental concerns, while providing a new framework for understanding IEQ variations across different architectural contexts. These findings advance our understanding of workspace optimization in research environments and provide practical guidelines for enhancing occupant satisfaction and productivity through evidence-based environmental design. |
