[esp-r] Re: surface fluxes

[Achim Geissler]

Hi

not sure what you mean. What turned out zero? All the values in the  
res-variables you name? Or your subsequent calculations? Anyway, there  
is no straightforward way to extract the U-value (if that is what you  
mean with comprehensive transfer coefficient) of a double facade  
construction.

I would recommend using a simple tool like WIS to compare your  
window / facade constructions in regard to basic parameters (g-value,  
U-value). And look at overall loads to compare the impact on the  
building as a system.

Regards
Achim
