Considering that, all countries are seeking for the ways to cut down the energy used in building sector. In the severe cold climate zone of northern China, where is needed to be heated for a long time but with low energy efficiency, great amount of energy has been wasted during the heating process. Although the design standard for energy efficiency of residential buildings there is up to 65%, the differences between operational and design energy consumption are fairly different. For the purpose of objectively depicting the heating energy consumption and indoor thermal environment of the residential buildings in Inner Mongolia, which stands for the severe cold climate zone of China, this research investigated 40 buildings in five places of three sub-climate zones within Inner Mongolia and recorded their heating energy consumption and indoor thermal environment data. This analysis reveals the considerable heating energy saving potential in the region. It will be helpful to improve the building energy efficiency through awaking the energy saving awareness of occupants and further implementing the energy retrofit program in this region.
