Hey Joerg,<div><br></div><div>If you look into the Engineering Reference document that comes up with EnergyPlus installation, you'll find that under "Window Calculation Module" title, it says that </div><div>
<br></div><div><div><font class="Apple-style-span" color="#000099">The primary Window calculation is a layer-by-layer approach where windows are considered to be composed of the following components, only the first of which, glazing, is required to be present:</font></div>

If there are two or more glass layers, the layers are separated by gaps filled with air or another gas. <i><u>The glazing optical and thermal calculations are based on algorithms from the WINDOW 4 and WINDOW 5 programs</u></i> [Arasteh et al., 1989], [Finlayson et al., 1993].

Hey there Joerg,<br>
<br>
I had a look through the documentation and couldn't find it.<br>
<br>
My guess is that the figures are harmonised with the IGDB which you
can download for free - in the form of Window 6.0 - from the LBNL
website. I tried to get an export of the figures but Window 6 is not
very export friendly so I've attached a screen dump instead.<br>
<br>
Cheers<br>

Hello,<br>
EnergyPlus uses default values for several gas properties
(WindowGas), for example air, argon, krypton. But they are not
visible for the user.<br>
Has anyone these default values ? <br>
Best regards, Jörg Huber<br>
