From the original poster, thanks everybody for your help on this. Chris’s post above was especially helpful. In the end, single pane glass would have required too large of a cooling unit to keep up, even before getting into the issue of condensation on the glass.
We went with insulated (double-pane) glass for the door and side panels, trying to keep the frames as minimal as we could.
I’ll post a photo of the final product if I can figure out how to upload it to this site.
Even a multi-pane glass wall would be energy inefficient in comparison to standard framed and insulated; same goes for a glass door vs insulated exterior grade solid door or custom equivalent or better.
I believe 1/4" single pane glass has an R-value around 1, and the best dual pane, argon filled, low E glass has an R-value around 4.
Here is a link to a “generic” chart that shows some options

The lower the U value the better - R=1/U
With a metal frame and no thermal break expect some condensation.
I have a regular interior door with double pane glass in Florida and it has done fine
