Feasibility Study on the Installation of Elevators in Old Residential Buildings in Beijing from the Perspective of dual aging – A case study of Xinjiekou Sub-district in Xicheng District

With the continuous evolution of urban and rural construction models in China, the installation of elevators in old residential communities has become a critical public welfare project aimed at enhancing residents' quality of life and improving mobility. Beijing is facing a dual aging challenge characterized by a high degree of population aging and significant community aging, resulting in an extensive and urgent demand for elevator installations in old residential communities. This paper focuses on the dual aging context, systematically analyzing the influencing factors of elevator installation in such communities, summarizing common installation methods and their applicable scenarios, and conducting an in-depth feasibility study based on cases from the Xinjiekou Subdistrict of Xicheng District, Beijing. The goal is to establish a comprehensive preliminary feasibility assessment framework for elevator installation in old residential communities, thereby developing a feasibility evaluation checklist for elevator installation projects in Beijing's old urban areas. This research aims to accelerate the implementation of elevator installation projects in old residential communities in Beijing and provide a reference for similar feasibility assessments in other aging communities.
