CFD can be used for site planning, natural ventilation studies, HVAC systems design, pollution dispersion and control (Zhai 2006), and it is one of the few tools able to simulate properly stratified ventilation (Chen 2009).
In addition, since ventilation studies have relied heavily on field experiments, ventilation studies require much time as well as accurate--and expensive--measurement systems.
General heating and ventilation studies, for example, may require velocity measurements that are accurate only within 10%, with designers requiring just the average velocity.
