日本集合住宅可持续维修更新机制研究与借鉴OACHSSCD

The maintenance mechanism of collective housing in Japan covers the entire process from design to implementation.In the design phase,the product lifecycle classification of the KSI system is adopted,and conditions for sustainable renewal are reserved in advance.In the maintenance planning phase,a sustainable maintenance and renewal plan is formulated once every 12 years under the guid-ance of the government and relevant associations.In the maintenance implementation phase,an im-proved maintenance model is applied based on active owner organizations and decision-making mecha-nisms.Meanwhile,external professional resources can be engaged to support the whole process,in-cluding building investigation and diagnosis,design consultation,consultation-based decision-making,and maintenance execution.These measures not only ensure the basic performance of build-ings but also continuously improve residential quality,thereby meeting the growing livability demands of society and owners.Drawing on Japan's experience will help China achieve the goals of construc-ting high-quality housing and improving the residential inspection and endowment insurance system,and promote the transformation of urban and architectural development toward urban renewal and in-ventory optimization.
