Abstract

With the progress of science and technology and the development of society, research on new energy-saving technologies and promotion of extremely low energy consumption buildings will be an important way to achieve energy saving and emission reduction in buildings in the future. Among them, as one of the passive energy saving technologies of near -zero energy buildings, external louvred shading can effectively improve the overall performance of buildings. Based on the existing theory of outer louver shading, a calculating model of reverse direct solar radiation of outer louver shading considering the installation distance is established. Based on Energy Plus energy consumption simulation, an external louver shading model for benchmark near-zero energy buildings and an external louver shading energy saving potential calculation model suitable for different styles and effects of architectural design, and a new parameter is proposed to represent the energy saving level of buildings: Shading energy Efficiency Index (SEEI) is used to evaluate the correlation between near-zero energy buildings and shading of exterior louvers, and the potential of exterior louver shading application to improve energy efficiency of external window system, and to evaluate the correlation between near -zero energy consumption buildings and exterior louver shading.
