At the beginning of the "Bird's Eye View" section the language used referencing the credit's intent states, in part, that its purpose is to "reduce the number of conventional commuting trips made to your building."

In reviewing the credit I can't find any requirement that the commuting be TO your building. The lack of such a requirement, at least in my opinion, leaves the possibility open for the commuting survey to document commuting practices FROM your building, as would be the case with residential applications.
