Can double glazing have advantages instead of triple glazing?

I read on the page of Konrad Fischer

So if you take Konrad Fischer as a source, the easiest thing is to commission him and design the house project with him.

Konrad Fischer is no longer alive.

I consider his theories at least interesting and worthy of discussion.

As long as the U-values are correct, it basically does not matter whether you have 2 or 3 panes. The heat radiation from the sun also passes through the additional pane without any significant difference.

I could imagine that it also depends heavily on the size of the window surfaces..... In my new build, one side of the living room, which is 70sqm after all, is almost an uninterrupted glass surface....

In this case, I would try to make the thermal behavior of the glass surfaces as "wall-like" as possible. You won't get there without triple glazing. Apart from that, in a reasonably well-insulated new build, you would rather want to shade from the warm spring days onwards than let in too much sun. Even on the coldest days in winter, the rooms become more comfortable if no cold surface temperatures occur on the inside of the windows.

but it also rather allows heat input through the sun from the outside to the inside.

And you really want that? Do you have any idea how warm windows get when the sun shines on them? Like radiators! Do you want to have radiators operating in summer? No? Then install triple glazing. It is better in summer and winter. In winter, when you need it, there is usually no sun due to the weather, or because of the shallow angle only from 11 am to 2 pm. The heat input is taken into account in the energy calculation, don’t worry, but it is simply a joke compared to the overall balance.

The argument about a poor insulation standard of the rest of the house is also questionable. The windows are usually the weak point. Even old walls and ceilings often still have better U-values than new triple-glazed windows.
