Re: [EnergyPlus_Support] LowTemperaturwe:VariableFlow

Radiant cooling is limited mainly by the m2 cold surface. Even at 16 degC, there is only so much m2 ceiling to transfer heat via convection to the air. Bring into the fact that high humidity forces you to either turn off the system or to increase the surface temp, you decrease the capacity even more.

1) dehumidify or
2) create more cool surface (walls, floors)
3) addition zone fancoils
4) decrease internal loads (yes this is the best, but show me an Architect that  will agree to smaller windows, even when having them will increase the occupant well being).

Hi, it's been a long time since I started my simulation but I can't let it work. My building is heated and cooled by a LowTemperature Variable Flow system, even if it seems to read correctly the Zone Air Setpoints, in too many zones it can't reach it. 
I cannot understand the reason of this problem because there are no severe errors at all.
I'll attach the Idf file

Ps if someone has any example of other building with this conditionig system could please send it to me so I can have at least a comparison? The Examplefiles are no useful for my problem.

Thanks a lot
