I have used RETScreen and understand a solar wall can be modeled within

enough juice so I have to incorporate solar air heating into this model.
Either that or autosize everything to get 300 and subtract the retscreen model
as an ECM.<o:p></o:p></span></p>

plenum walls Trombe-wall and just fiddle with it until it works, maybe. I
can spend a minute on it and try. Either way its modeling reality, right?
There should be a lot more discussion on this. Someone must have
submitted an energy model with solar air heating to USGBC using equest.<o:p></o:p></span></p>

<p class=MsoNormal style='margin-bottom:12.0pt'>You could also experiment with
creating a space of type "plenum" with the dimensions and properties
of a solar wall. If I were taking the experimentation route, this is
where I would start.<br>

I've modeled a SolarWall, aka "Solar Air Heating" or transpired air
collectors using <a href="http://www.retscreen.net/" target="_blank">RETScreen</a>.
They have a Solar Air Heating module that is included in the RETScreen 4
download. If you don't mind modeling the SolarWall separate from the rest
of the building, then that should work pretty well.<span style='color:#888888'><o:p></o:p></span></p>
