Research on the Interactive Renewal of Residential Outdoor Spaces in the Context of Aging

Residential outdoor spaces serve as the most significant venue for home-based older adults' outdoor activities. Their livability and age-friendliness have become key topics of active discussion in recent years and a crucial aspect of urban residential renewal. This study focuses on the behavior of older adults and residential outdoor spaces, drawing on theories such as ecological psychology and environment-behavior studies. From an interactive perspective, it explores theoretical methods for the interactive renewal of residential outdoor spaces—including concepts, principles, and an Age-friendly Design Framework. Through field investigations of typical residential samples, the study examines the interaction process between older adults and outdoor spaces, identifies existing issues, and demonstrates the feasibility of integrating interactive renewal with outdoor space design. Furthermore, it proposes design strategies for the age-friendly renewal of residential outdoor spaces, thereby supplementing research on the "space-behavior" interaction and enhancing the overall age-friendly quality of residential environments.
