<div> Hi,</div>
<div> I am studying the effect on the urban climate of flat-plate collectors<br> integrated in the buildings' frontages. To do this study, I am trying to<br> model a urban canyon . My idea is to create two zones with TRNBuild, one
<br> modeling the canyon street and the other one modeling a building. The<br> problem is that the street should be open to the upper atmosphere and with<br> TRNBuild I have to define a wall. I have created a window which is entirely
<br> transparent to solar radiation to do as if there was no window. But I<br> don't succeed in defining this window as a wall. I mean I am obliged to<br> define a wall and after to add a window to this wall, but the window can't
<br> have the same area as the wall. So do you know a way to define a window as<br> an entire wall?<br> Thank you</div>

<div><br> P.S.: I would be interested in any other ideas about how to model a urban<br> canyon with Trnsys and TRNBuild</div>
