[EnergyPlus_Support] A question about the baseboard



Dear all

   In my study, I want to study the effect of solar radiation on the heating system.

At first, I selcet a weather file which's solar radiation is samll. 

Second, I use a high solar radiation weather file.

In order to compare the differnts between the tow case, the s urface Int Convection Heat (including all wall and window ) and the infiltration Sensible Heat Loss is added.  This result are used to compare with the Baseboard Heating Rate.

For the first case, the two value is almost equal, but For the second case,

the two value is differnt, there are about 12% error.

One day result is shown below:

Zone Mean Air Temperature

Baseboard Heating Rate

Sum of all Convection Heat Rate and Infiltration Sensible Heat 

The difference between two value  

I think the difference between two value  should be :
