Make them better looking and push-button retractable from inside, and people will want them.
evasive_chimpanzee@lemmy.world 9 months ago
I haven’t watched the video yet, but vernacular architecture back in the day commonly set shading elements like awnings at the right height/angle such that during midday in the winter, sunlight would still directly go through windows and hit interior floors and walls. During summer, the angle of the sun would be high enough that direct sunlight could not reach windows.
You can get pretty far with just those passive designs. There are tools to help you find the dimensions you’d need based on where you live without having to do any calculations yourself.
Glowstick@lemmy.world 9 months ago
While that may be true, it doesn’t make people want them any more than they currently do. People want to have their full window view available whenever they want it. This means it needs to be retractable and extendable at the push of a button. And once you have that, it’s easy and helpful for it to also be automated
Evotech@lemmy.world 9 months ago
It’s expensive. I got quoted 10k for 4 windows
TheIllustrativeMan@lemmy.world 9 months ago
This is the real reason they disappeared - awnings cost money and don’t increase square footage. That’s also why every modern building is a boring box.
We didn’t forget about them, it’s still covered in architecture school. You can even make them look really cool. But they cost money, and that’s a hard barrier to cross.
echodot@feddit.uk 9 months ago
You can buy them off the shelf and then put them up yourself. Of course then you have to calculate the amount of pain it’ll be to put them up and the fact that it’ll never be as good as getting it done by professional. Plus in my case they’ll be a lot less blood involved.
10 grand does seem like a lot of money though. How large are your windows?
ladicius@lemmy.world 9 months ago
Better quality of living (in the long run even living longer) and less energy consumption on the AC may change that calculation.

I’m Suprised people don’t just paint everything white in really hot countries. I’ve always felt that would probably help a lot.
True it would probably look bad a lot quicker.
NegativeInf@lemmy.world 9 months ago
If I could find it and it was as durable as regular paint, I would paint everything that white that converts visible lights into infrared that isn’t blocked by the atmosphere. Yeet that heat right the fuck back into space damnit!
Pirky@lemmy.world 9 months ago
That reminds me of the barium sulfate paint that was discovered a couple years ago. It’s so incredibly good at reflecting/moving heat that it could even cool whatever it’s painted on. I’ll have to find a source on this again…

always been confused why roofing in the NA area is often black, or close to black, it simply doesn’t help anybody.
evasive_chimpanzee@lemmy.world 9 months ago
It’s cause they are built from petroleum
blueeggsandyam@lemmy.world 9 months ago
I don’t know for sure but I assume of it is because light roofs require more maintenance to look as nice. Nothing shows up on a dark brown or black roof. A white or light grey would show dirt and debris. I don’t want to waste my time washing my roof because my HOA doesn’t like the way it looks.
smort@lemmy.world 9 months ago
Also, the color doesn’t make that much of a difference. Like a percentage you can count on one hand. Much more significant gains can be had from ridge vents and other ways of getting the heat out of the attic, and insulation to keep that heat from going into the house.
At least according to my acquaintance in the roofing industry, and obvs this is regarding typical US/Canada SFHs
halferect@lemmy.world 9 months ago
That combined with building materials, where I live we build out of Adobe and my house stays warm in winter and cool in summer, the outside looks like mud smeared on the walls.

KillingTimeItself@lemmy.dbzer0.com 9 months ago
our house was built in the early 2000s. It has an awning.
Why were they forgotten? Probably because manual awnings suck, and once extended if it’s windy, it’s a rather fun time having it out.
Other than that, they’re pretty good. I actually plan to experiment with passive building cooling using a similar technique, instead of an awning, it’ll be a diffusion sheet of light fabric to block direct sunlight exposure to the walls, hopefully providing a decent bit of cooling, but naturally, i have to get around to testing it in the first place.
OminousOrange@lemmy.ca 9 months ago
Awnings don’t have to be a piece of fabric flapping in the wind. Wood, metal, extended roof overhangs, a deciduous tree, really anything that provides exterior shade to a window will be quite effective at reducing interior heating.
Cethin@lemmy.zip 9 months ago
If you want one that retracts then fabric is probably the best option. I guess you could have a hard material that’s made if panels that slide over each other, but that’d likely be a lot more expensive without much benefit. Alternatively you can have the vertical metal covers that extend and retract.
KillingTimeItself@lemmy.dbzer0.com 9 months ago
it’s meant to be temporary and easily replaceable, the idea is to put it up during the summer so it blocks most radiate heating of the building, and then take it down throughout the rest of the year so you can still get a good view out the window.
I could also do dedicated window awnings, or retractable ones, but that’s not my style. But yeah you have a good point. I was thinking about a different kind of awning initially lol.
Zipitydew@sh.itjust.works 9 months ago
Better idea. They’re called trees.
PancakeBrock@lemmy.zip 9 months ago
As a guy who does concrete. Trees close to your house love to drive roots through your foundation. Trees are great but can really do some damage. Especially where I live. Ground water is about 80’ or deeper. The tree roots here stay shallow and spread out everywhere.
mojofrododojo@lemmy.world 9 months ago
one of our neighbors has a 60-ish foot tall spruce about 14’ from his house. There’s a betting pool on whether it’ll squish his place or one of his neighbors in the next big wind storm.
Tinks@lemmy.world 9 months ago
Honestly, I kinda hate the big tree in our front yard. It has these tiny leaves and every fall we have to clean the roof and gutters repeatedly until it finally drops everything, because those stupid leaves stick to everything and clog not just the gutters but the downpipes. This tree has caused our basement to flood during fall because one storm can simultaneously blow off a ton of leaves, instantly clogging the gutter, and then pour rain down the front of the house. We spent hundreds of dollars last year on a new gutter solution for 6ft of gutter. You read that right. Six feet of gutter cost us about $450, and they STILL wouldn’t guarantee it would fix the problem because of the stupid tree.
We keep the tree trimmed and healthy, but every time the trimmers come out I dream about telling him to cut the stupid thing down. Awnings would be easier -_-

Trees create a cooling effect past shading the area. It’s a combination of shade and evaporative cooling.
elephantium@lemmy.world 9 months ago
Is it not enough that trees look better?
awesome_lowlander@lemmy.dbzer0.com 9 months ago
Better idea, they’re not mutually exclusive
KillingTimeItself@lemmy.dbzer0.com 9 months ago
trees near buildings are a nightmare, they can often grow weirdly due to lack of sun, and often make maintenance and clean up on the tree itself a nightmare, if it grows to close to your house you need to do something about it. They are also generally liabilities during storms, especially if they hang directly over your house.
Like a previous commenter said, they can be problematic for foundations and driveways and things like that. It seems fairly common that surface level root structures will expose themselves and start to pop through the top layer of dirt, primarily due to soil erosion and compaction i imagine, but that’s another problem for grounds keeping as well.
Speaking of grounds keeping, trees make grass grow really inconsistently, and also generally provide “dead spots” where the grass will get almost no sun, and almost certainly die. Also mowing under them is hard. Trees don’t really grow at human accessible heights all that often. And when they do, they’re not as good for providing shade.
Zipitydew@sh.itjust.works 9 months ago
I live in Chicago. So does Alec. Stop the video at 5:44. All the trees are doing far more cooling and shading to the entire area than shitty old window awnings blocking single windows.
LordCrom@lemmy.world 9 months ago
Florida used to build houses with metal awning you would fold down over the window for hurricanes. We did away with those because hurricanes got stronger and would rip them off turning them to flying projectiles. Now we have panels and no awnings. Because of hurricane codes

This article is from 2019 and argues against the methods laid out in research article published at the same time. It does not provide adequate evidence to support your claim that thid is a myth. I Will do some more research later today, but this author writes for a think tank. I’d advise some due dillignece before reading this guys material. Forbes is also right leaning so will have some level of bias here.

Can’t you just take them off? I’ve never lived in a part of the world that has hurricanes but I have lived in properties with shutters and you can take them off, you tend to do so in the winter because they’re just pointless for the year.
Buelldozer@lemmy.today 9 months ago
I was watching this earlier and got about halfway through before the power went out. I spent the next 90 minutes before it came back on trying to imagine a style of these that would look good on the south side of my house.
I didn’t come up with anything that my wife would let me install so I guess I’m going to stick with my plan of automated shades or drapes.
OminousOrange@lemmy.ca 9 months ago
Interior shades aren’t nearly as effective as exterior. Once that sun gets through the window, it’s already giving that next interior surface quite a bit of heat.
There are many styles of awning or other shading elements. You can have metal slats or what looks like a wood box that comes out horizontally over the window. I’m sure something could fit your house’s aesthetic. And perhaps ask your wife what value she’d put on thermal comfort.
Looking for shading elements or shading strategies might get broader results than simply sheet metal or fabric awnings.
ladicius@lemmy.world 9 months ago
Interior shades are a special kind of heating.
CeeBee_Eh@lemmy.world 9 months ago
I just got awnings installed two months ago on the windows that get sun for most of the day. It dropped the temps in those rooms by almost 8 degrees Celsius on hot days. The AC even runs less during the day now.
They’re simple retractable awnings that a local guy installed for me. I used to hate the idea of awnings, but the thought about IR heat getting trapped clicked with me recently and suddenly the idea of awnings seemed brilliant.
solarvector@lemmy.zip 9 months ago
I don’t think the look good.
And literally never thought about it more than that.
So people may not really know what they’re for, just that they’re “old-fashioned”. Not sure how to make them trendy but that seems to be a deciding factor in how people invest in their homes. Maybe sell them with “live laugh love” printed on the front with wine bottles dangling from the corners?
NegativeInf@lemmy.world 9 months ago
Just start doing it and brag about your electric bill going down. Eventually others will do the same for the same reason. Then it becomes a trend for being a thing people are doing.

I’ve got a large plate glass door in the side of my house, and I’m thinking of installing a pergola outside it. Grow something on it that gets nice and leafy in the summer and bare in the winter.

I live on a street corner, and the house across the street from me fronts onto the road we don’t share, if that make sense. It’s like my house points ^ and his house points <. So my house faces his side yard, and he’s let it kind of go native, complete with these gorgeous wild muscadine vines. They’re native to the area and they thrive with no attention at all; I have it on good authority those vines have been there for 60 years. That’s my plan.

If the argument is that awnings are too unattractive for people to use them, then hot damn is that so much worse. Solid metal gates - for when you want your house to look like a convenience store in a bag neighborhood when riots are about to start.
blackbirdbiryani@lemmy.world 9 months ago
These are soooo common on old houses in Melbourne. I’ve never met anyone who lives in one, but they’re often closed all year which is insane to me (are these people sitting in the dark in their living rooms??)
DarkThoughts@fedia.io 9 months ago
The most common ones are made out of very thin plastic. There's also older ones out of wood. The most common ones are out of aluminum, so not strictly protective. Steel shutters are rather rare on houses and more something stores would use.

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.
RunawayFixer@lemmy.world 9 months ago
These things are technologically obsolete imo. The same result can be achieved with glass coatings, while requiring no 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 on 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.

Some people decided awnings are unattractive so now every HOA and rental bans them. And the rest of us have to suffer because the pretty people who can afford to pay that A/C bill run our entire society.
This is the entirety of what’s wrong with the US in a microcosm. The majority being forced to live under rules made by people that aren’t affected by them.
