Abstract: (21 Views)
Background and Objective: Rapid urbanization in Iran has increasingly alienated residents from nature, raising concerns about declining mental health. The biophilia hypothesis suggests that exposure to natural elements can restore psychological well-being. This study aimed to investigate the impact of biophilic components on happiness in residential complex residents and identify the most effective natural elements.
Methods: This descriptive-survey study employed a quantitative approach with 120 residents of the Binalood residential complex in Mashhad, selected through cluster random sampling. Data were collected using a researcher-developed questionnaire (33 items) with good reliability (Cronbach's alpha = 0.88) and content validity (CVI = 0.87). Exploratory factor analysis confirmed construct validity (KMO = 0.85). Data were analyzed using Pearson correlation, regression, and path analysis.
Results: Natural light was identified as the most effective component (40%). The exterior space generated greater satisfaction (46.7% vs. 23.3%) and happiness (50.8% vs. 20.0%) than the interior courtyard. Biophilic components explained 56% of satisfaction variance (R² = 0.56), with plants (β = 0.42), natural light (β = 0.35), and natural views (β = 0.28) as significant predictors. A strong positive correlation was found between green space use and happiness (r = 0.58). Path analysis revealed that stress reduction mediated 52% of the biophilic effect on happiness.
Conclusion: Biophilic components, particularly natural light, plants, and natural views, significantly enhance happiness and vitality through stress reduction. Revising Iranian housing design with emphasis on optimal natural lighting and developing public green spaces is essential. These findings highlight the need to integrate biophilic design principles in contemporary Iranian residential complexes.
