[EnergyPlus_Support] ceiling, adiabatic surface or not?

["pizzaalan" <pizzaalan@xxxxxxxxx>]

Thank you very much for those who helped me before. 

I simulated 3 story building without adding any HVAC system first. 
If I set all ceilings between any two stories to adiabatic walls, 
then mean air temperature of third floor is close to outside 
environment temperature. Say outdoor temperatue is -21 C, then mean 
air temperature of first level is 18 C, second level is -2 C, the 
third level is -20 C.

If I add the heat transfer between each story by setting that each 
ceiling's outside surface environment object is floor of its upper 
level, then now outdoor temperatue is still -21 C,  mean air 
temperature of first level is 15 C, second level is 9 C, the third 
level is 5 C.

Should mean air temperature of each story be very close? Should I 
view ceilling as an adiabatic surface or not? 

Thanks again.

Alan
