I'm interested in how one might estimate the energy savings if one

Good luck finding them. In this area they are non-existent because
they didn't sell. You may have to lift them to open the windows too.
The Low-E with gas were more efficient and cheaper and stocked.

Triple pane are certainly not common, and from what I remember of my
window days, LOW E Argon double glazed are slightly better than the
best non-gas-filled triple glazed units.
You want sealed units with the thermal-break separators, not the
aluminum ones, and constructed with the 2 or 3 sealant method, not the
simple urethane.  Vinyl framed windows with the Rehau profile
extrusions are about the best you can get.Last better than wood, and
every bit as good insulation value.

They were readily available 10 years ago when I built.


How do you know that they're "non-existent" in your area? Did you poll
all the builders or owners of new homes in your area? Of course not,
you just made up your declaration as usual.


Baloney. Triple glazed windows are most often coated and filled just
like dual pane, and perform better. See page 3 and 4 here
