This paper illustrates a step-by-step process on how to use a procedure for verification, validation, and reporting of indoor environment CFD analyses developed by ASHRAE. The details of the procedure are further explained through an example of indoor environment modeling (an office with mechanical displacement ventilation). The verification, validation, and reporting do not have to be documented in a uniform format, but they do have a very similar procedure. The emphasis of the verification and validation is problem dependent. The computational fluid dynamics (CFD) user plays an important role in the verification and validation. An accurate and successful simulation is a combined effort of the CFD code and the CFD user.
