Nearly zero energy consumption building aims to achieve zero energy consumption and has become an effective way and a main goal of building energy conservation and emission reduction. By tracing the origin and development process of nearly zero energy consumption buildings, this article discusses the similarities and differences of similar concepts and the basic ideas towards nearly zero energy consumption buildings. In view of the classification of overall strategies of nearly zero energy consumption buildings in the current research situation, this paper also discusses the division method of overall strategies for low energy consumption and high production capacity, which is convenient for balance measurement. Based on the overall strategy, a technical framework of nearly zero energy consumption building is constructed, and the main technical measures, characteristics and development trend are described.
