I often create a number of parametric runs for my clients which compare,
among other things, changes to mechanical systems.  Sometimes creating the
energy model early in the design process requires me to make changes to
zoning, geometry and systems for the final LEED model, but hey, using
modeling to make design decisions is what it was designed to do, isn't it?

In my experience, even after modeling 100's of buildings, there is not
always one good answer for every building.  Changes in space use, occupancy
levels and existing building conditions have large impacts on mechanical
systems choices (not to mention budgets and available fuels).
