How could I simulate U.P.V.C window frame and curtain types in energy plus software

[Bahareh Amiri]

Hi
I want to simulate a window with P.V.C frame window with low-e glazing and curtain .I have searched in energy plus data for window frame and curtain but i have not find any thing
Would you please help me
Best regards

Hi

I think u can model your window in WINDOW( LBNL software) and then take report for e+! but Im n't sure!! :) 

Good Luck

Hi,

1) This is a vinyl frame exported from Window 7. The frame has a U-Value of 1.7 but the resulting 2d conductance, which should be entered in EnergyPlus is 2.33. You should refer this in your fenestration surface (frame and divider name).

2) Low-e glazing can be easily simulated by choosing the right glazing material from WindowGlassMaterial data set.

3) By curtain, I guess you should use WindowMaterial:Shade as it can be used for diffusing materials such as drapery and translucent roller shades.
