Re: [EnergyPlus_Support] Heat gain through wall_Output Variable



Thank you. When i try to use following variable the heat gain has negative value. Any thoughts?

Output:Variable,*,Surface Inside Face Convection Heat Gain Rate,hourly; !- Zone Average [W]

Javed,

 

Here are some examples:

Output:Variable,*,Surface Inside Face Convection Heat Transfer Coefficient,hourly; !- Zone Average [W/m2-K]

Output:Variable,*,Surface Inside Face Convection Heat Gain Rate,hourly; !- Zone Average [W]

Output:Variable,*,Surface Inside Face Convection Heat Gain Rate per Area,hourly; !- Zone Average [W/m2]

Output:Variable,*,Surface Inside Face Convection Heat Gain Energy,hourly; !- Zone Sum [J]

Output:Variable,*,Surface Inside Face Net Surface Thermal Radiation Heat Gain Rate,hourly; !- Zone Average [W]

Output:Variable,*,Surface Inside Face Net Surface Thermal Radiation Heat Gain Rate per Area,hourly; !- Zone Average [W/m2]

Output:Variable,*,Surface Inside Face Net Surface Thermal Radiation Heat Gain Energy,hourly; !- Zone Sum [J]

Output:Variable,*,Surface Inside Face Solar Radiation Heat Gain Rate,hourly; !- Zone Average [W]

Output:Variable,*,Surface Inside Face Solar Radiation Heat Gain Rate per Area,hourly; !- Zone Average [W/m2]

 

Note that you should specify in your IDF:

Output:VariableDictionary,IDF;

This will create a .rdd file which contains a listing of all possible report variables.  There are literally hundreds (or more).  I have only shown a few samples ? there are more that might work better for you.

Hi,

 

I'm trying to get total heat gain through external wall in a zone. I found following variable gives surface heat gain.

 

Surface Inside Face Net Surface Thermal Radiation Heat Gain Rate 

Surface Outside Face Solar Radiation Heat Gain Rate  

 

Can anybody suggest me what output variable i need to choose for this??

 

Thanks,
