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

[Jon Hand]

In ESP-r a low e glass system is represented by altering the air gap resistance. 
Keep changing this value until the reported U value for the construction is 1.9.

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

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,
