I can think of a couple ways to approach this.  Not necessarily
"simple" but perhaps "simpler".
It depends a little on how important the geometry of the structure, sun,
and solar distribution is to your result.  Usually, in a 5 story
building -- you are probably talking an office building -- the internal
loads and other factors are more important than the solar
distribution.

1)  One way to simplify is to model floors 1, 2, and 5 and then use
a "zone multiplier" on all the zones in floor 2 to get the
proper loads for the HVAC system.  (Zone multiplier would be 3 -- to
account for floors 2,3,4).  Your DXF output would have a missing
section, however.

2)  What would give a better picture (DXF) and would accurately
model all the solar distribution would be to use "relative"
coordinates for your input.  A bit of cut and paste in a text editor
is required as well as making sure the right zone is set for the right
surface but you can just change, then, the Zone origins to affect a
different location for the floor.

3)  There is probably a "macro" approach that could do #2
for you as well but I think Mike Witte will have a better suggestion as
to whether that would be possible or not.
