Welll... "need"????

Issues include: buildings tend to rent by the floor, and various
FD regs govern penetrations and safety cutoffs. 

But if those are solvable; real pluses are you can use low-grade
"core" space for both, with better floor loading. (Many buildings
are like WTC -- the support is in the center, everything out of
that is "hung" out there.) 

And you segregate the machines from the fumes... ALWAYS a
good idea.
