Re: [EnergyPlus_Support] Re: Run period result difference

[Linda Lawrie <linda@xxxxxxxxxxxxxx>]

As Jean indicates, the day type of the weather file/run
period could make a difference.

There are other things to consider as well:
ShadowCalculation -- by default is every 20 days.  If you are trying
to match results from two different run periods, you probably should make
this 1.

Loads Initialization (the parameters in the Building Object).  If
the convergence values are too loose, even though the warmupd days
converge -- you may not be getting the conditions resolved sufficiently
for your building.  Set them tighter, perhaps, use "report
during warmup" to make sure things are converging as you
think.
