An interesting project that I worked on recently involved looking at affect of wind in the atrium and corridors and a six story office building.

I produced this rather pretty CFD model which show that indeed the air speed would increase through the corridors.

This steemed from a simply query from the architect and as we already had the CFD model for the building it was a rather simple task to produce this information. The upshot is that the architect as able to make a quanatative assesment of the design and modifactions required.
