Re: [EnergyPlus_Support] Temperature (low) out of bounds ERROR



Notice that "small" internal heat gain of >200 W/m2. That is far too large and is probably an input error in your lighting or Equipment object.
You should correct that and see if the simulation works better.

Hey

I am working on an Energyplus model. I am stuck with this severe error and i don't know how to rectify.


Severe  ** Temperature (low) out of bounds [-111.35] for zone="ZONE 2", for surface="SW2WALL"

   **   ~~~   **  During Warmup & Sizing, Environment=HYDERABAD ANN CLG .4% CONDNS DB=>MWB, at Simulation time=05/21 15:40 - 15:42

   **   ~~~   ** Zone="ZONE 2", Diagnostic Details:

   **   ~~~   ** ...Internal Heat Gain [211.473] W/m2

   **   ~~~   ** ...Infiltration/Ventilation [0.000] m3/s

   **   ~~~   ** ...Mixing/Cross Mixing [0.000] m3/s

   **   ~~~   ** ...Zone is part of HVAC controlled system.


Both from other sources and also from .err file, the reason why this error is coming is 


 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 internal 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:NoMass definitions.


I have checked everything. Materials, geometry, I can internal Gains everything is alright.

Please if anybody knows what exactly to do. What should I change or What should I look in?

Thank you
