Hi All,

I created my model in the new 2014 version and I am running 2010 compliance. I have assigned all the windows with a net U-value (inc. frame) of 1.8 W/m2K. However, in the BRUKL output the Ua-calc for windows appears to be 0.9 W/m2K. Can anyone help?????? I spent too much time trying to figure out why this is happening.

Thanks,

Eleni

Thanks about that.
It was indeed because of the curtain wall.
