Abstract: The evaluation of nearly zero energy buildings is of great significance to guide the design and ensure the healthy development of the industry. This paper summarizes the international mainstream nearly zero energy building evaluation system, points out the nearly zero energy building evaluation framework with Chinese characteristics. The energy efficiency indicators, technical scheme and technical characteristics of the first batch of 12 projects with ultra-low /nearly zero /zero energy evaluated by China Academy of Building Research was analyzed. It is found that it is a mid-to-long term development trend suitable for all countries to gradually improve building energy efficiency and achieve nearly zero energy first and then realize zero energy. In the first demonstration projects, the average building energy saving rate of public buildings reached 83%, and the average level of primary energy consumption of residential buildings was 56kW/h/（m2·a）.The nearly zero energy building evaluation has been gradually transformed from an early stage of trial to practical application.

Key words: ultra low energy building; nearly zero energy building; zero energy building; evaluation system
