[esp-r] U-value low-e glass

[Felipe Durán]

Dear All,

I am creating a double glazing system construction with a layer with a low-e glass. According to the manufacture, the U-value is 1.9 w/m2 K. I have modified the materials and the optics database based on LBNL window 5, but the U-value always remains as 2.8. Its seems that the problem maybe related with the low-e coating location. ¿Does anybody knows how to create a low-e glazing system with a u-value 1.9?

Kind regards,
