Abstract：In response to global climate change，China has put forward the strategic goal of "carbon peaking and caron neutrality" and accelerated the development of near-zero energy consumption buildings according to local conditions，which can effectively reduce the energy consumption and carbon emissions of the building industry. By expounding the origin，definition and development background of near-zero energy buildings，explaining the technical features of buildings such as climate and energy saving，and extracting and analyzing two elements of green building，energy-saving space form and renewable materials under the influence of regional climate. It is combined with an exemplary existing case to describe how to achieve near-zero energy consumption buildings in severe cold and cold regions. It aims to promote the practice and development of green，energy-saving and low-carbon buildings in the field of architecture.
Key words：nearly zero energy building，climate zone，energy efficiency level，passive design，low carbon
