Construction and Design of an Aging-in-Place Model for Residential Bathrooms Based on Digital Twin Technology- A Case Study of Bathroom Renovation for Elderly Individuals Living Alone in Beijing

Abstract

Amidst accelerating urbanization and intensifying population aging, the quality of life for mobility-impaired individuals and society’s adaptive capacity to aging are directly influenced by the level of accessibility facility construction in homes. Currently, the home environment in China generally suffers from insufficient awareness and outdated facilities regarding accessibility, necessitating urgent improvement. This study focuses on the residences of elderly individuals living alone in Beijing and employs a combination of on-site surveys, questionnaire investigations, perceptual data acquisition, and Digital Twin technology. The methodology aims to precisely identify and quantitatively evaluate the domestic barrier-free environment. The findings provide a scientific basis for the age-friendly and disability-inclusive renovation of living spaces, holding significant practical implications for enhancing the convenience and safety of the elderly and mobility-impaired populations.
