Anybody else having a problem with elevated air speed (over 40 fpm)? I have a commerical office building with ceiling diffusers with 60 fpm and the credit has been audited for elevated air speed. In this case occupants cannot adjust the diffusers. Seems like this has been cleared up in the ASHRAE 55-2004 addenda such that the graphical method can still be used to demonstrate compliance, but was wondering if anybody else has encountered this, and if so, how did you document the credit?

The credit language says you need to comply with ASHRAE 55-2004 without addenda. The easiest way to comply is to demonstrate your design criteria is within the ASHRAE perimeters by using the ASHRAE Thermal Comfort Program. See the "Documentation toolkit" for samples.

You can program it as well, using Scilab, Matlab, or any other.
