Environmental Optimization Analysis of Outdoor Flow Field of a Campus Building in Changzhi City, Shanxi Province via CFD Simulation

Energy is becoming a growing concern in the twenty-first century, and energy saving in buildings is a very important development direction, and CFD simulation can greatly understand the flow field distribution around the building to achieve the goal of building energy savings. The outdoor flow field environment of a campus building in Changzhi City, Shanxi Province, is used as an example for optimization analysis in this paper. The design first employs fluid calculation software to simulate the building's external flow field with CFD, then adjusts the orientation and layout of the building based on the simulation results, and adds more structures to ensure that the building can maximize the use of natural ventilation to reduce indoor load in summer and have a small amount of cold air infiltration in winter. According to the results of the paper, the CFD simulation demonstrates that the solution can make better use of natural ventilation to reduce the summer load, and that for the winter load, the cold wind infiltration velocity of the entire teaching building and some major places of the complex building will decrease, but will increase the load of other buildings, such as the art and sports building.
