[EnergyPlus_Support] Re: availability manager - surface temperature

["christian1855" <christian.schiefer@xxxxxxxxx>]

Mike,
I've taken a closer look to the control scheme. Now I found a second 
problem: 
The radiant system depends not directly from the outside temperature. 
It depends on the average dry bulb temperature during 8:00 and 20:00 
(hourly measured). 
Is it possible to get a average node temperature?


Christian

PS: Is it planned too add such features to the next release?
