These things are technologically obsolete imo. The same result can be achieved with glass coatings, without requiring the extra work to install/maintain or replace these appendages.
These awnings work against losing heat to the night sky, the same effect of which can be achieved with anti emissive coatings that reflect heat radiation back inside.
The awnings also work against the sun when it’s high in the sky, for which there are now anti solar coatings which will reflect more light from certain angles.
Nostalgia is nice, but the modern solution is easier + cheaper to install and maintain.

I’m afraid to admit that I have not, will do it this evening but until then I will remain ignorant.
Edit: Just skimmed through it because I couldn’t wait and the video did not change my opinion at all.
The presenter seems to be unaware that there exist glasses which reflect different amounts of light depending on the angle. Up north, where he lives, the angle of the sun is much lower in winter than in summer. There exists glass that is designed for that.
A large awning to create extra seasonal living space outside, sure, those are still great. Small window awnings like ik the thumbnail picture, definitely not, those are a waste of time and money.
I was also disappointed by how dismissive the presenter was of scientifically based findings that did not align with his feelings. Curtains work great.
There’s literally a whole section on glass coatings. But he makes the point fairly reasonably that in large parts of the world the climate is extremely seasonal and so you don’t necessarily want glass coatings because they affect the glass all year round. Is a good point really perhaps you live in a temperate climate and so are not as cognizant of this.
The curtains bit is especially stupid because obviously curtains heat up and then radiate that heat back into the room so no they don’t block heat they block light. If you want it to be dark then you have curtains if you want it to be cool they don’t do anything.
