This paper outlines a method for optimizing cleanroom design using FloVENT airflow modeling software. To a large extent, these new methods dispense with old empirically-based techniques and allow each new air flow design to be created without relying on past experiences or mock-ups of the space being designed.

The work presented in this paper is based on an actual project. A cleanroom was modeled using air flow rates determined through empirical techniques based on heat loads to the space from machinery and occupants. A sensitivity study was then carried out to assess the effect of optimizing air flow design to and from the space.
