I was told that you could simply specify the soil fill as "External Air" and specify the temperature of the soil for it. The results should still be correct this way.
Then, in the next Dialog, you would not define a "Soil".
This is a workaround but it will achieve what you are trying to do.
This is not workaround. This is the only proper way. The "Soil" environment is not a working tool at all. It is not working as it should do. Currently it works as a simple material, but is not analyzed during the calculation.
Also, there is no point (in the current edition) to define the temperature at all. unless you are interested in the temperature inside the construction. Anyway L2D value (for some reason called PSI in EcoDesigner) has units W/mK. So there must be just the temperature difference, no matter how big. Inportant are the surface resistances.
Maybe Graphisoft wants me as the energy efficiency engineer in their team?
