Abstract

The main purpose of this study is to establish a design strategy framework for residential building refurbishment in urban area of China. By studying of the advantage research and case studies in Europe, complete methodology and innovation technology would be proposed as the result of this research. Exploratory research for energy conservation design strategy for residential districts is also drawn up. The result of this research would cover the shortage of energy conservation design strategy for existing residential building refurbishment and also put forward the instructional principles for low carbon emission city development. Through the literature review, building energy consumption in the world level is summarized and comparison between that of Europe and China is made to improve the fesibility for making research on the topic of urban residential building refurbishment in China. By the analysis of influence elements for existing residential building in urban area, reasons for implementing residential building refurbishment project could been summarized into three aspects.
