 Definitely going to be inside the building. I suspect having it outdoors would require a much hardier design and likely a lot more material for it to be effective. We also want to have a more attractive interior to the classroom, and we think a natural wood wall (should we stick with this design) would level-up the interior.

This would be quick to implement, and do a good job of air-sealing the whole opening without fussing around the door gaskets, tracks, and joints in the door.
		
 I like this, as it seems less labor-intensive and intrusive than things inside the building. I'll approach Paul with this idea and see how he thinks this might work.

 These may be materials that could augment the outdoor seal that Kenneth describes above. Nice. :)

 Another useful idea! I think the rolly shelves are tall enough. Maybe not wide enough, but we could line two of them up together, reconfigure the room somewhat, and I think this could be managed.
 
 
I appreciate everyone's input! If anything else comes to mind, please post in here. Thanks again! :)
