Abstract：The energy-efficiency retrofit of existing buildings provides effective solutions for reducing energy consumption and greenhouse gas emissions. The effectiveness of energy-efficiency retrofit depends on the appropriate technologies. On the basis of identification of the college building energy consumption characteristics and commonly used retrofit technology，this paper analyzes the connotation and technical path of energy-efficiency retrofit of existing buildings in colleges and universities. Taking the retrofit project of the teaching building of Jiangnan university as an example，analyzes the technical decision-making of the retrofit，and puts forward technical suggestions for energy-saving renovation.

Keywords：existing buildings；energy-efficiency retrofit；technology decision making；colleges and universities
