[EnergyPlus_Support] Setpoint temperatures not achieved in space





Hi all,

I am modeling a performing art/theater building in Eplus. I am trying to calibrate the simulation to the metered data and therefore am looking at the run period of 12/25 - 12/31 when there is no occupancy and minimal internal loads. However AC system is still running 24/7 (shocking I know). The building is located in CO so during this period the outdoor dry bulb is 17F - 25F. My heating setpoint in the space (AHU with VAV reheat boxes) is 70F. However the zone mean temperatures in the ballroom space is 22F (bascially 5F above outdoor at all times) so obviously the set point is not being met.
I have ramped up the fans and heating coil capacities but am still seeing these extremely low temperatures. I've also tried turning off the OA but the zone temperatures are remaining the same. The only thing that seems to change these temperatures is if i increase the internal load in the space or change the weather file. How can I increase these zone temperatures in the space so that the system is meeting the setpoints without changing the internal load.

I am really baffled by what is going on here and would appreciate any help if possible.
Thank you for your time,

Celia
