According to the US DOE, Low-e glass is significantly better than
regular glass, BUT which way the treated surface should face depends on
whether one wants to prevent heat loss from the building in winter or
heat gain from outside in summer.

So what do you do when you live in a region with significant temperature
variations, such as Michigan?

How significant are the variations? I live in the desert, so I know
what my choice would be. Consider the rising cost of your Winter
energy cost, I guess?

Well, if you simply want to minimize conduction and IR transmission,
why would you care which way you orient the window? I wouldn't, and
don't- AFAIK the glass units in my windows are not directional.

It's not just surface-stuff. Low conductance also.

treated in ....

I thought of that, but I'm not sure that the factory-replacement glass
assemblies for our doors are available that way. I'll have to check.

they reflect heat. you either want it reflected back outside, or reflected
back inside. you don't want it to trap the heat between the 2 pieces of
glass (the layer goes on the inside of panes in a double glazed window).

The answer came already: the Low-e coating is on one side only, but the
glass assemblies are reversible. Reverse them each fall and spring?

I really wonder how much of a different there is. I suspect little. It
will reflect heat both ways.

Hope these couple of links, give you a better understanding on how Low-e
works.
