I've always found that the trick is to figure out what the heat-load of
the room is and figure out what your repair/response time is in the
event that the AC shuts down.
ie: one of my machine rooms is surrounded on 5 sides by concrete walls,
under ground, and will, if necessary, run just fine with the doors open
for a couple of days, especially if I shut down some non-critical
systems; in the event of an AC failure.
I run this room fairly warm. About 22C.
I have another machine room in another facility that will not run by
itself even with the doors open and critical systems turned off. This
one I run down to 16C; and if the AC shuts down, I have about 6 hours
to respond before the temperature gets high enough to start being a
problem.
I know, not scientific or 'procedural'....
