I can second that. However, I will say that I believe the differences are small enough, both for glazing and for opaque constructions. I have posted a guide for converting/constructing complex glazing for eplus from EU-glazing data under dokumentation on our website. The film coeff. for opaque surfaces are also very very close and the handling of thermal bridging is good and in Germany you can use the calculative or 2D sim methods to do these.

I recommend some caution when modeling with these values. I know that the glazing test methods are different between US and Europe (different temperature difference). I have to recalculate European glazing for my US clients. European glazing will always have a lower U-Value (higher thermal resistance) than the exact same configuration in the US. Iâ??m not sure what kind of modeling exercise you are working on, but just understand the playing field.
