Based on the rational utilization of natural wind, it is particularly critical to study the role of natural ventilation convection in zero energy buildings, so as to reduce building energy consumption and lay a good foundation for realizing the goal of zero energy consumption in buildings. The commercial software PHOENICS is used to numerically simulate the outdoor wind environment of the building complex layout and the indoor ventilation of the building itself. After a comparison analysis of simulation models, this paper first points out the main factors that affect the wind environment and indoor natural ventilation of the building complex. Reasonable suggestions were given to the architectural planning and design as well as the living habits of the residents which can save energy to the greatest extent. With these suggestions, the unnecessary energy consumption of air conditioning can be reduced on the premise of ensuring the indoor temperature and humidity environment which is very beneficial to the realization of zero energy consumption of buildings.
