The application of CFD software in building energy conservation is presented. The most important is the application of energy saving in HVAC. The advantages of CFD software in building energy saving are pointed out and the problems need to be further studied. Introduction CFD Computational Fluid Dynamics (CFD) is a discipline that solves fluid control equations by numerical methods to predict fluid-related phenomena such as fluid flow, heat transfer, and chemical reactions. Commonly used methods are finite difference method, finite element method and finite volume method. The basic idea of ​​CFD analysis is as follows: The original
