Re: [EnergyPlus_Support] Thermal Comfort

["Michael J. Witte" <mjwitte@xxxxxxxx>]

1.  The weather conditions and the HVAC system response can change 
every timestep.  Would this explain the changes you are seeing? 

2.  The thermal comfort models in EnergyPlus do not limit the 
reported values in order to draw attention to times when the comfort 
conditions in the space have become unbearable.  Check your values 
for activity level, clothing level, air velocity, zone air 
temperature, and mean radiant temperature.
