I am getting the following error:
* Severe * Temperature (high) out of bounds (200.28] for zone="00.7.CAFE", for surface="SURFACE 604" * ~~~ * During Warmup, Environment=GENEVA ANN CLG .4% CONDNS DB=>MWB, at Simulation time=07/21 08:30 - 08:35 * ~~~ * Zone="00.7.CAFE", Diagnostic Details: * ~~~ * ...Internal Heat Gain [117.696] W/m2 * ~~~ * ...Infiltration/Ventilation [1.670E-002] m3/s * ~~~ * ...Mixing/Cross Mixing [0.000] m3/s * ~~~ * ...Zone is part of HVAC controlled system. * Fatal * CalcHeatBalanceInsideSurf: Program terminates due to preceding conditions.
and then these suggestions: *** ===== Final Error Summary ===== *** The following error categories occurred. Consider correcting or noting. *** Temperature (high) out of bounds *** ..A temperature out of bounds problem can be caused by several things. The user should check: *** ..1) the weather environment (including the horizontal IR from sky) *** ..2) the level of interal gains with respect to the zone *** ..3) the thermal properties of their materials. And other things. *** ..A common cause is a building with no or little thermal mass - all materials with Material:NoMassdefinitions.
However, I have tried each of these suggestions and nothing is working. I have a LEED baseline model running for this building with a standard VAV reheat system. For the proposed case model with the error, I have put the exact same geometry, constructions and internal loads in as well as plant loop. The difference is I have radiant ceilings and a DOAS. I have modelled this system multiple times without error but for some reason this time there is something wrong. Can anyone suggest where I should look for possible solutions.
As always thanks in advance for the help. Annie
