The aim of this research is to identify long-term development goals as well as to clarify the situation and problems of urban dwelling service facilities in order to establish an assessment system for sustainable urban dwelling service facilities. First, this study attempts to define and set goals for sustainable urban dwelling service facilities, proposing assessment framework which includes performance of basically living requirements, environment protection and adaptability. Based on the assessment framework, the research has carried out case studies of four major urban areas in Taiwan. The result showed that urban dwelling service facilities could match user’s basically living requirements defined by this research. However, there is a lot room to improve when orienting in the reduction of energy and resource consumption as well as environmental impacts from the view point of life cycle analyzing results. The actual situation of urban dwelling service facilities is also far away from the ideal, especially when looking at building adaptability in order to respond for new user requirements and the use of new technologies to preserve existing cultural and environmental aspects. Second, based on the System Assessment Method and the case study results, the study proposed a draft of the sustainable assessment system for urban dwelling service facilities in Taiwan. This system is formed by three levels: assessment aspect level, issue level and indicator level. The assessment aspect level includes environment and human wellbeing aspects. The environment wellbeing aspect has three major issues and twelve indicators. The human aspect also has three major issues and six indicators. Besides, each assessment issue has two kinds of indicators: the design performance group and the operating performance group. In the assessment application, indicators belonging in the design performance group aim to check the sustainable potential of a project or existing building. Indicators in the operating performance group aim to clarify the real sustainable state of existing buildings.Finally, results of each indicator group can be integrated into a sustainable barometer figure to show the total assessment result. The barometer of this system consists of two axes, human and environment wellbeing, reflecting the whole system theory. The verification showed the system basically matched all assuming criteria defined by this research. The research results also proved the users could implement the system based on common technologies available in Taiwan.
