<br><font size=2 face="sans-serif">Thanks for your answer.</font>
<br>
<br><font size=2 face="sans-serif">I think your suggestion about adding
a wall gain to the boundary wall sounds good. I can use the window model
in the TESS Loads & structures library to compute the solar gain.</font>

<br>
You can also define your wall with Identical BOUNDARY condition, and define
your window as an "additionnal window" which will be adjacent.<br>
<br>
I think you may also define your wall as boundary and put a wall gain,
which will be equal to your window solar gain (you may model that in Studio
outside Type 56 and define that gain as an input in your type 56)<br>
<br>
If you define a ficticious zone on the other side of the wall, you will
have to define 2 walls - at least - in that zone. <br>
<br>
Best regards</font>

<p><font size=2 face="sans-serif">Hi all,<br>
<br>
I wish to model a greenhouse with a boundary wall towards another greenhouse,
and with little or no heat loss through that wall. For this, I could have
used the IDENTICAL boundary condition. However, I also wish to have a window
in that wall, to capture solar radiation coming through it. This is not
possible with a BOUNDARY wall. Is there any way of setting the temperature
on the back side of a wall with a window?</font>
<p><font size=2 face="sans-serif">I have an idea which might work. I can
define a ficticious zone on the other side of the wall, and set the temperature
in this zone equal to the setpoint I have in the first zone, to minimize
heat loss. Then I can define the wall as ADJACENT, and have a window in
it. Is this approach OK? Should I set the convective heat transfer coefficient
of the ADJACENT wall to the standard inside value of 11 on both sides?
Is it OK with just one wall (the adjacent wall) in the ficticious zone?</font>
<p><font size=2 face="sans-serif">Thanks for any help,</font>
