BUILDING INTELLIGENCE AT THE INTERIOR SCALE: SYSTEMS INTEGRATION IN HIGH-END RESIDENTIAL DESIGN

The evolution of high-end residential design is increasingly influenced by the integration of intelligent systems at the interior scale, enabling spatial environments to function as adaptive and performance-responsive ecosystems. This study investigates the impact of systems-integrated interior infrastructure on environmental responsiveness, occupant comfort, automation efficiency, and energy optimization within residential environments. A performance-oriented analytical framework was employed to evaluate the interaction between embedded technological components and spatial performance outcomes using variables related to environmental regulation, predictive automation, and behavioral adaptability. The results indicate that higher levels of spatial intelligence significantly improve thermal adaptability, lighting automation efficiency, indoor air quality stabilization, and ergonomic adaptation, while simultaneously reducing cognitive load associated with manual environmental control. Subsystem-level analysis further reveals that predictive automation enhances response time and usage prediction accuracy across HVAC, lighting, ventilation, and shading systems. Correlation outcomes demonstrate strong associations between environmental responsiveness and occupant comfort, as well as between predictive adaptation and user experience. Additionally, the study identifies a positive synergy between energy efficiency gains and user satisfaction across progressive intelligence tiers. These findings underscore the potential of performance-oriented interior design frameworks in enabling intelligent residential environments that support sustainability, operational resilience, and enhanced experiential quality through seamless technological integration.
