Reconstruction of the existed buildings to improve energy efficiency is a key field of China energy efficiency strategy. In this paper, firstly, the author analyzes situations and problems of energy consumption of existed buildings in China; secondly, the author compares the energy efficiency measures of Chinese existed buildings with German existed buildings; thirdly, by referring to the German experiences on energy efficiency reconstruction in the existed buildings, the author studies the approach to promote energy efficiency of existed buildings; lastly, the author discusses the additional relative measures and provides some advices to governments. The goal is to promote the energy efficiency of existed buildings, and accelerate the execution of building energy efficiency strategy and realization of sustainable development in China.
