Abstract：
With the rapid urbanization in China, the issue of energy shortage has become more and more serious. As one of the industries with high energy saving potential, energy saving technologies of construction industry are frequently discussed in recent years. Among the factors usually considered in technology selecting, energy saving potential and economic cost are the most significant ones. Building insulation materials and ground source heat pump are selected for case analysis in this paper. Energy saving quantity and life cycle cost-benefit of the two technologies are analyzed. The calculation guidance method discussion and case analysis can offer theoretical direction for selection of building energy saving technologies.
