I think the problem is that you are not conditioning that zone and the high internal heat is causing a surface temperature to become incorrect. It does not make sense that the surface temperature is too low, but perhaps if you condition the zone, the problem will be resolved?

Ok, Jim,
thanks for the extremely fast reply, more information is added here:
** Severe ** Temperature (low) out of bounds [-518.20] for zone="8PAV:ESTERILIZACAORAPIDA", for surface="8PAV:ESTERILIZACAORAPIDA_PARTITION_5_0_11363"
** ~~~ ** During Warmup & Sizing, Environment=SUMMER DESIGN DAY IN SAO PAULO, at Simulation time=01/15 20:00 - 20:01
** ~~~ ** Zone="8PAV:ESTERILIZACAORAPIDA", Diagnostic Details:
** ~~~ ** ...Internal Heat Gain [4006.000] W/m2
** ~~~ ** ...Infiltration/Ventilation [4.447E-003] m3/s
** ~~~ ** ...Mixing/Cross Mixing [0.000] m3/s
** ~~~ ** ...Zone is not part of HVAC controlled system.
** Fatal ** CalcHeatBalanceInsideSurf: Program terminates due to preceding conditions.
...Summary of Errors that led to program termination:
..... Reference severe error count=1
..... Last severe error=Temperature (low) out of bounds [-518.20] for zone="8PAV:ESTERILIZACAORAPIDA", for surface="8PAV:ESTERILIZACAORAPIDA_PARTITION_5_0_11363"
************* Warning: Node connection errors not checked - most system input has not been read (see previous warning).
************* Fatal error -- final processing. Program exited before simulations began. See previous error messages.
----------------------------------------------------------
Is the "6" of the 4006 W/m2 maybe the problem? should I indicate 3999 W/m2 for example?
Any detective hunch?
thanks.
