MODERATORS
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.
Well, I hate to disappoint you, but curtains work for energy savings. If you are open to changing your mind, here's an explanation: https://www.thermal-engineering.org/thermal-curtains-material-home-energy-saving/
You always want glass coatings on outside window glass, no matter the climate. Depending on where you live, you want different coatings obviously, but coatings are essential in modern glass panes.
And since you seem to be entirely unaware of what already exists in the construction industry, here's another article with a bit more explanation: https://en.aaglas.nl/producten/warmtewerend-glas. A low zta will stop a good portion of the summer sun, while a high lta will still allow through a lot of light from low angles (including from the weak winter sun). Select glass that has a high lta/zta factor and you have glass that is good both in winter and in summer in northern Europe. The Netherlands is at lattitude of about 52°, while most Canadians live a few degrees south of that, so these same solutions would work there as well.
I need to put up some windows in the Hague, you seem to know your shit, care to pm me your company or contractor?
I would ask the window system producers for contractors near you, try: https://www.schueco.com/nl/particulieren/raamsystemen And/or https://www.reynaers.nl/
