Assessing the adaptability of old community for renovation based on health sustainability

Due to the lack of feedback analysis tools, it is impossible to assess the adaptability of a renovated community for different users. Therefore, this paper discusses the adaptability evaluation system for renovated communities from the perspective of healthy sustainability. The correlation between the adaptability of older communities and both relevant subjects and objective environments was analysed. Two significant findings were obtained. First, an innovative adaptability evaluation system was developed using rough set theory, structural equation modelling and importance–performance analysis. This system assessed different attributes of the capital system (social, economic and environmental) and different indicators in the area of health sustainability. Second, the system usability was verified through the study. In this way, the correlation between space health, environmental health, service health, health performance optimisation and health adaptability after community renovation was obtained. The results also showed that spatial changes significantly affect the adaptability and health performance (e.g. elderly-oriented performance, juvenile fitness and energy utilisation performance) of communities. These performances need to be optimised further in community renovation. This study provides a simple and applicable tool for evaluating the effectiveness of community renovation, thus ensuring more sustainable renovation practices.
