An Analysis of Restorative Space Design Standards
摘要
Restorative environments play a significant role in supporting mental well-being, particularly in high-stress contexts such as workplaces, healthcare settings, and educational institutions. Although existing design standards address psychological restoration, they typically provide fragmented and selective guidance. This study addresses this gap by proposing a comprehensive, theory-based framework that integrates three environmental psychology theories, Attention Restoration Theory (ART), Stress Recovery Theory (SRT), and Perceived Sensory Dimensions (PSD), into five key Restorative Affordances: Retreat, Engage Softly, Spatial Coherence, Tailored Fit, and Express Identity. Using qualitative content analysis, spatial features were systematically evaluated from five restorative space-related international standards and guidelines: WELL v2 (2025), Interface, Design Justice Design Space (DJDS), WELL v2 Q2 (2022) Pilot, and Fitwel. A structured scoring system assessed the explicitness and multi-scalar coverage of restorative strategies, with results visualized through comparative charts. The results reveal that no single standard offers comprehensive multi-scalar provision for all affordances. WELL v2 (2025) demonstrates consistent performance in spatial structure and sensory privacy; Interface excels in tactile comfort, biophilic integration, and adaptable layouts; DJDS leads in personalization, inclusivity, and cultural expression; WELL v2 Pilot (2022) enhances outdoor restorative opportunities; and Fitwel provides macro-scale separation and site adaptability. When considered collectively, the strengths of the standards complement one another, forming a more complete framework that provides continuity from detailed sensory elements to broader environmental strategies. Integration addresses scale-specific gaps, generating layered restorative experiences that enhance attention restoration, stress recovery, and belonging. This synthesis underlines the value of cross-standard approaches, moving beyond the limits of individual frameworks to support adaptable and inclusive environments. The study contributes methodologically by applying a theory-based, multi-scalar comparative assessment and offers practical direction by showing how integration of complementary strategies can guide the creation of holistic environments that realize the full restorative potential of design.
