RE: [EnergyPlus_Support] Zone Air Balance Surface Convection Rate




I know there are different ways to control the calculation of  the heat entering and leaving a zone with windows and shades. .
 
If you only  want to investigate the effect of a window component of the zone, you may change the transmittance and the conductance in the material used for the window and observe the result.

Transmittance will control the radiation component and the conductance will control the conduction component of the heat transfer.
 
Window heat lost occurs in Summer night as well.  Winter sun will increase the zone temperature.
 
You can also add an external shade or internal blind to block the radiation. 
 
I call these the non-expert, analog ways of simulation control.  I use a one zone building to improve my understanding of the various available report variables.
 
There are also Average,Zone, Window heat gain and heat lost values reported in the simulation result.

Subject: [EnergyPlus_Support] Zone Air Balance Surface Convection Rate




Hi, i am trying to find the heat transfer through out of the the walls in a zone. i fount the variable "The Zone Air Balance Surface Convection Rate" wich is the sum, in watts, of heat transferred to the zone air from all the surfaces.

is this includes the total heat transfer though the windows (sum of gains and looses) ?

and if yes, then if i remove the window heat looses (for example, only at the winder heating period)then the residue is the heat that have been transferred though the walls ?

thanks in advanced
