In my case, the building is located underground and surrounded by rocks. The question is how to calculate the heat flux from boundaries or the walls into the building. What kind of output variables should I get from the EP results?
Have you tried with Output:Variable "Surface Inside Face Conduction Heat Transfer Rate" ?
Thanks for your advice. Yes, I've tried that, but there are too many surfaces in my case. In order to calculate the heat flux from the rock to the cavern, I should pick up the surfaces between them and it seems like a mission impossible.
Why not? This is exactly the variable you need, all the rest is a question of post processing - you can sum them in Excel or whatever. There is another variable Zone Air Heat Balance Surface Convection Rate - it gives you the sum of convection rates from surfaces in each zone.
