I’ve been planning for the last year some eco home upgrades, and awnings on the south facing windows are high on the list. With so many possible upgrades and so little money it’s difficult to know what to do first.

KillingTimeItself ,

do the cheapest and most simple things you can do first, even if minor, it provides a small window for you to royally fuck up and gives you some room grow into

Awnings would likely be a pretty cheap and impactful one.

I’ve put 500mm of insulation in the loft, plenty of mistakes made there.

Just managed to get an electric awning to go over the lounge window for £140, fingers crossed it all goes well and if so I’ll do the upstairs windows too.

15 more things on the list though.

KillingTimeItself ,

don’t worry, the list will grow shortly enough :)

There is always something new to be doing unfortunately.

In my house in North Carolina, I put up radiant barrier foil in the attic. It was cheap and made a huge difference in the upstairs temperature. I stapled it to the joysts so there was an air gap on both sides of the foil, and so that the hot air would rise out of the roof vents.

No offense but they are also fucking ugly

It sure why you’re being downvoted, it’s is unfortunately true. Makes your house look like a diner most of the time…

Most suburban houses he was showing in the video look hideous and not because of awnings.

papertowels ,

There’s modern louvre versions that look good.

AA5B ,

Cool, thanks for pointing those out. I really need something like that

There’s a house near me who has disgusting cheap awnings on their house. I want them so badly to just take them down. They have all kinds of trees casting shade on their house anyway.

Why do you care that much?

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.

You haven’t watched the video have you?

RunawayFixer , (edited )

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.

echodot ,

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.

racemaniac ,

Lol, you’re bothered by him not watching the video, and now you’re not reading his comments XD. He already said in the previous comment there are glass coatings that work dependent on the angle of the sun, so coatings that will have different effects in different seasons, so he already addressed the possible issue of glass coatings working all year round, and said that according to him it’s not an issue if you choose the right coating.

echodot ,

I am reading these comments they’re just uninformed and he’s pushing this view that he has which is fine but he’s not watched the videos why the hell is he commenting about it.

And why do you care so much, I just feel that in a sub-related to videos, people should possibly watch the videos before commenting and making irrelevant comments that are already addressed in the video, but you go ahead and be a dick

racemaniac ,

Yeah, and on a discussion space it’s probably also best that you actually read the comments you’re replying to. He felt that the video wouldn’t teach him anything since he’s considers himself already knowing a lot about the subject.

I just pointed out the irony of you being bothered about him not watching a clickbait video about a topic he believes he already knows more about that such a video can teach. And you then tell him the video makes points he already dismissed.

He might be a bit abrasive how he entered the discussion, but if he works in the industry and knows why awnings are no longer a thing, and already dismisses the points the video made against more modern technologies since he seems to know what modern technologies are actually like… that does seem actually useful to this discussion. I get him not wanting to waste 20 minutes…

RunawayFixer ,

Hey, thanks for sticking up for me. Noone else seems to dare go against the bandwagon.

Personally I don’t get people, I provide sources and am open to alternate viewpoints, but most people just want to blindly believe whatever last video they watched unfortunately.

racemaniac ,

No problem :)

Keep posting useful info on topics like this, we need more factcheckers on clickbait videos about how centuries old technology would still be the best.

    I’m no expert on this subject at all, i’m not pro or contra awnings, i just felt bad for someone going into deeper detail on modern techologies getting downvoted for not agreeing with the video because he works in the industry, while making good points (and having his points ignored)

    If you have a situation were awnings worked really well, and are cheaper than modern alternatives, awesome, well done :)

    I’m not assuming any of the people discussing here are doing the voting, but also in the discussion his points were being ignored. And i love me a good technology connections video too, but someone from the industry dotting some of the i’s that technology connections missed was interesting :)

    Btw, thanks for also discussing in good faith :). And your example of awnings in Mexico (and how the most modern technologies are indeed not available/practical everywhere) is also a great contribution :).

    RunawayFixer ,

    Well, I hate to disappoint you, but curtains work for energy savings. If you are open to changing your mind, here’s an explanation: thermal-engineering.org/thermal-curtains-material…

    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: 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?

    RunawayFixer , (edited )

    I would ask the window system producers for contractors near you, try: www.schueco.com/nl/particulieren/raamsystemenAnd/or www.reynaers.nl
