The number of abandoned buildings is on the rise following the collapse of the economic system.Diverse reutilization projects of these empty buildings have been propelled by local government for regional development. Especially, alteration of local government-owned empty buildings for public welfare facilities come first corresponding to community demands.But how to reach an agreement on project plan for remodeling public welfare facilities is still in dispute by various stakeholders due to lack of integrated procedure and performance standards.And the research to define the extent of building impact in regional context and develop assess factors for the project goal, sustainability is a challenge of building science that should be empirically proved.

This study was conducted on the remodeling project of public welfare facilities related to Self-Rehabilitation in pursuit of sustainable development of the region.Self-Rehabilitation is specialized strategy for urban regeneration in Korea,similar to Community Development in UK and Neighborhood Renewal in USA. A mixed-method approach was proposed to define sustainability, select impact factors and develop assessment model focused on the optimized implementation.Qualitative research by conducting field work for finding factors and Quantitative research by conducting Delphi survey for factor weights from May 2012 to December 2013 were combined for this assessment model. And for implementation, this model designated local government officials as final decision makers according to institutional practice. All information of this model modified for them based on the appropriated information technology.

This study introduced specialized efforts for sustainability in Korea and its possible implementation to specific building type and scope.In detail, this model tried to address the integrated remodeling procedure and performance standard within institutional context.And this model emphasized the importance of the local government official and assisted them to take the responsibility of sustainable Building Delivery for the local community. Furthermore this assessment model may contribute to the communication among various stakeholders for building remodeling procedure and performance extended to sustainable regional development.
