I would look at the convergence error (ie. load and temperature comparison) EnergyPlus is reporting.
In my opinion the default load tolerance is extremely low (0.04 watts, 0.136 Btu/hr) in comparison to any normal space heating or cooling load 1,700+ watts (~6,000 Btu/hr). This represents an error of 0.0000235%! Not something to be concerned about. I think you could safely increase the default load tolerance to something like 1% of your smallest load and still be plenty safe, especially if you are already using heating and cooling sizing (safety) factors.
The default temperature tolerance 0.4°C (~0.7°F) is more reasonable and may be somewhat loose for spaces that require tight temperature control; so I would keep an eye on this and only loosen its tolerance for projects that do not require close temperature controls.
