Mike:

Sun angle, sun angle, sun angle !! 

You also didn't mention which way the guest tower was oriented, say as a
tall thin tower with facing directions dominating East and West. The
rest of your hotel is undoubtedly space where internal loads and outside
air are the primary load drivers.  The guest rooms get a smidgen of OSA
and internal load driving it.  October 2 in New York City could also be
an 80 DegF day as well.

I will bet on eQuest (or DOE-2).

The LS-B Space Peak Load Components Report shows my peak cooling load
for a perimeter hotel room with windows occurring on Oct 2 at 5pm when
its 62F outside in new york city.  I believe this is an error.  My peak
heating load for this space appears correct occurring on jan 23 at 8am.
Solar radiation dominates the total space load at 75% of the total
cooling load.  The overall building peak cooling load occurs on July 1
at 8pm when its 92F outside which appears correct.  What do you think?
