Awnings: a simple cooling tech we apparently forgot about

[@TechnologyConnections]

A note on sun angles throughout the year: I included (then removed) a section in the script where I explained how the correct overhang on a South-facing window will completely block the sun in the summer when the sun is high in the sky, but will let sunlight pass in the winter when the sun is low in the sky. A remnant of that lived on when I discussed those really fancy home design techniques. The reason I decided to remove it was that there are plenty of places on Earth where this is irrelevant! If you live where heating your home is rarely if ever a concern, then that sort of selective blocking wouldn’t be important to you. You’ll want to block the sun all the time! And in any case, since adjustable awnings are a thing, a discussion on ideal overhang angles felt too weedsy. But, since a few remnants of that discussion remain, I wanted to leave this explanation so you’re not confused.

[@brianmiller1077]

My Uncle had a 70's designed house that had a couple of cool things long overhangs on the south facing picture window A square design with the stairs to the basement in the middle. It had a hallway that went around the entire house

[@MichaelSteeves]

I've got a south-facing window in my office. In the summer it is not bad. In the winter the blinds need to be closed all day, otherwise the sun will be shining on the far side of the office!

[@TheReedsofEnki]

A lot of modern houses just don't have overhangs and I hate it. In addition to the wrap-around porch and other things, many rural farmhouses plant a row of deciduous trees along the southern property line that provide shade to the house and grounds in the summer when they have their leaves and in the winter allow more sunlight through to the same space. Its the same thought as the overhanging roof but expanded out to the area around a house.

[@ahmedel-sayedosman2951]

An architect here. The weather in North Africa gets really hot in the summer (more than 40 degrees Celsius or 104 F) and most of my clients request these automatic aluminium shutters which are quite ugly and make all the windows look like mini- garages, but they do a great job in reflecting most of the heat and direct sunlight. The issue that it's either you solely rely on artificial light or just turn the house into a glorified greenhouse. What most contemporary architects do is actually look back at how traditional houses were built because they were excellent at utilizing materials and shade to naturally cool down houses by A LOT. One of the techniques used is that the awning is actually part of the building, where the window seems like it is indented in the wall (which is either built thick 50cm or almost 20 inches or it is a double wall with air between them that act as an insulator. ) or carved in and almost no direct sunlight reaches it unless it's late afternoon and by then it isn't that hot. the thick walls also help a great deal with not letting the heat reach the internal walls. Some old houses have horizontal wooden slanted louvres called "Shish" and that blocks the sun without blocking airflow and it is surprisingly effective. Another technique which is genius is the use of windcatchers, where a chimney-esque structure is built but facing the wind (Which is NW where i live) and that "catches" the cool breeze. Cold air is heavier so it descends until it is heated back up again and escapes through other openings that are high near the ceiling creating a cross-ventilation system and you have natural cooling all day long. some old lavish houses in Old Cairo even have a dedicated livingroom with a water fountain right under the windcatcher to introduce humidity to the dry desert wind and make it even more pleasant and cooling. It baffles me how these are solutions that are tried and true, much cheaper than AC, more aesthetically pleasing and more environmentally friendly, yet everyone opts for AC that just dumps more heat making outdoor spaces unbearable in the summer.

Growing up, my grandparents' house (built in the 50s) in Miami had corrugated aluminum thicc boi awnings, which served double purpose as storm shutters. When a hurricane was a few hours away, I would go outside with my grandfather and disconnect the poles holding them up, then screw the bottom of them into an anchor point below the window. So much easier than buying plywood or putting up single purpose shutters. Edit: Found them, they're called clamshell awnings.

Between that and the trees in the front and back yard, heat from the sun entering the windows probably isn't a huge concern for them.

[@d.aardent9382]

Very interesting. Ive been drawing up different solutions to my solar heating problems and one of my ideas has been building shade walls outside the main walls so i can either have fencing to grow a living shade producing vines or using the sunblocker fabric fence/covers along the secondary wall. I also thought on creating entire secondary outer wall to block sun and storms wind and rain, snow, ice as we have a very wide range of weather and seasons here. But blocking as much of the sun off house to me would be the best function, as it would eliminate most all my overheating issues as long as i insulated the ceilings of rooms from attic space. But we just had new roof put on abd they installed series of new vents, and that really made a difference in getting the heat out, but we have attic fans also, so the air is always moving up there anyway. I had ideas for something like you are describing also, but figured due to the height on the south side of house where most of these would be, it would require too much labor adjusting them all the time, as its so high,id need to use ladders to do that. Im trying to create something with as little need for adjustment as possible, and my plans kept increasing the size of coverage of the awnings. As for the shade walls, i was trying to decide which would be more cost effective and all seasonal useful, the entire large shade wall or independent awning system on house on different sides. But as my design for awning building kept making them increasingly larger, thats when i thought maybe i should just put the money into total wall shading construct. And i could grow plants on it also.

Scrolled a bit, did not find a comment on it, but won't read 5k+ comments, so here it goes. "European" roller shutters are double walled. They do not get hot from the inside. Some even have extra insulating foam inside. The window does not get warm. Their added bonus is that they provide extra isolation in the winter, too. Keeping the cold out. Also, they provide protection from the elements. Hailstorms are no match for those shutters. They can also be closed all the way, if properly installed, providing a blackout effect on the light, so you can sleep better during the day. Last but not least, they provide added sound proofing. PS. a few spelling corrections.

Rolladen are amazing. The instant relief when you close one on a sunny hot day. No, the windows definitely don't get hot - the main issue with them compared with awnings is that they block the light and view completely. It can be a bit depressing sitting in the dark. Personally, I haven't noticed a big soundproofing effect - and when it's windy, they can be very noisy, rolled or unrolled. Wasps sometimes try to nest in them, but if you make sure to open and close them daily then they don't really get very far. On the plus side though they can be electronically controlled and presumably some of the more up to date versions would be smart-enabled as well. Certainly there is an office building I go past frequently where I assume they are smart controlled because it seems that either every single blind is closed in the building or they are all open. BTW the fabric awnings seem to be in common use here in Germany too, especially in apartment blocks. They can look a bit retro, but they work. I don't think they work as well as Rolladen but it's definitely something.

Hey there! I work as a blueprint designer for a fabric production business that primarily works in awnings, both metal and fabric! I think a large part of awnings fading away in residential appliances that wasn't discussed was the tightening of government restrictions and building codes. Back in yesteryear, there weren't a lot of solid, universal restrictions and standards, so awnings could be designed and installed inexpensively by relatively cheap labor. However, things have changed, and now building codes, permits, and licenses muddy the water. Awning frames have to be thicker, especially for climates with harsher weather, the fabrics have become heavier and higher quality, engineers have to be consulted to determine structural integrity not just for the awning but also for the building its attached to. All of this red tape and regulation, while it is a good thing, has drastically risen the prices of awnings, especially when you consider that the cover may need to be changed in less than a decade. The frame does make up most of the cost, so a recover is considerably expensive, but if you're using a luxury, decorative fabric or a vinyl covering, a recover could still cost thousands of dollars. Anyways, all this to say tha4 thankfully, not all awnings are fading away. The company i (admittedly just started to) work for has expanded a good deal lately, and we still gave more work than we know what to do with.

[@mindstalk]

What about building in a rigid overhang?

[@johnhaller5851]

I expect that building lines and lot line setbacks can contribute to the red tape. The commercial awnings shown didn't extend past the front of the building and were quite narrow. A house with a zero lot line on one side might not even be able to install awnings on that side.

Another good option to reduce heat are solar/UV reduction film you can install on the inside of windows. They reflect most of the solar heat outside while still retaining an unobstructed view of outside. They have an added benefit of giving you privacy during the day since people outside will only see a reflection when trying to look in. I recently had these installed on all my windows and notice a significant difference. I can comfortably sit in direct sunlight in my home and barely feel the heat. They do tint the windows a little bit though, but still allow most light to still come in.

When we took down an old and ailing tree we quickly learned how much shade it had been providing. We added a covered deep porch across the entire southern face of our house; it provides more shade than the old tree did and the house is cool on the hottest days we are currently experiencing.

[@Bob-nc5hz]

If you want even better insulation, close up the porch into a verandah, it provides a nice space in the spring and autumn which is open and light but protected against the cold, in winter it adds a layer to the facade, and in summer the still air is insulation despite the insolation. Even more so if you add rolling exterior shutters (or blinds but that's not as good unless they're highly reflective)

[@jarivuorinen3878]

@@Bob-nc5hz Without rolling shutters or further awnings there's again problem with greenhouse effect inside the veranda. Open space on the covered porch has natural ventilation, and the temperature on porch won't noticably rise higher than air temperature anywhere else. If you put any obstructions there that limit the natural airflow, you'll have hot air standing there in sunny weather and that is then against house wall. Not optimal solution.

[@KoroWerks]

​@@jarivuorinen3878as an option, one could get a bunch of sliding glass doors from habitat for humanity restore or an apartment renovation, and you can leave them open during the summer and close them as the weather cools. We have a "sun room" that was once a deck and was previously renovated to be included into the house, they even cut through the siding and added a louvred vent so the heat and AC reach that space if you choose. It isn't perfect, and shade cloth blinds/drapes can be almost as good in winter at blocking wind or sun, so there are options, but it all depends on the home and the needs of the owner. Greenhouse effect is important to note, some people in the house seem to think keeping the glass doors closed in summer is better insulation FROM the heat, but I'm pretty sure it just puts more work on the AC, and heats up that room more.

That's basically one of the lectures I got at my 1st year of architecture. Generally we try to use external shading solutions whenever it's possible. The rule of thumb is that the same shade (ie from shutters) inside of the window is worth 30% of the shade outside the window.

​@@Superiorplatypus I'm not sure if they indeed lost popularity in a global sense. I think it depends on the area and local fashions. In southern Europe (i.e. Greece) they are still very popular. Almost every new residential building there has some sort of an awning system installed. Generally we try to design the windows, their, shape, placement and shading with permanent architectural solutions, whereas add-on awnings often feel like an afterthought (and they usually are). Awnings also often need to be mechanical in some way to adapt to the changes in the external environment. You need to fold/roll/lift them when you want to increase the window's exposure. This means extra complication (especially since they are out in the elements). They can break and need to be serviced, so people are generally a bit reluctant when it comes to installing them.

[@KairuHakubi]

​@@Superiorplatypus I have to imagine it's that the average modern person has no time or inclination to go outside their house and do stuff to it like stand around folding up an awning or pulling down an exterior shade. Neighbors are no longer people you're happy to see. and if you have another story, forget about it. I'm not getting out a ladder for that. I think a good solution is more windows need to have far more easily removed screens, so that you can reach out from inside and pull an awning or shade down, then replace the screen.

@18:15 As someone who has roller-shutters on their windows, a couple of thoughts: (1) The windows themselves are double- (or triple-) glazed. So, if you keep the window closed behind the shutter, it doesn't matter how hot the shutters get or whether there's heat trapped between the shutters and the glass - the shutter and trapped-air is acting as another layer of insulation between you and the outside. It's normally pretty cool inside in this configuration. (2) If the shutters are part-open (eg. @18:30) and the windows are open behind the shutters, you can set up a nice through-draught. This can be quite nice at night because, if necessary, you can close the shutters fully when you get up so that you're keeping out the heat of the day. (But I guess if you have air-con then you won't be opening windows, so this isn't that useful.)

Honestly, looking at US house construction from a European standpoint is shocking no matter where you look. And I'm not trying to be the "matchstick houses"-type commenter here, but I'm serious. On virtually all levels other than the concrete foundation, US building construction is shoddy at best. It's like code regulators, builders and customers simply refuse to learn anything over the years. In Europe you can only build houses that are virtually energy neutral, in the US they just slap a bigger AC unit and heater on the building to keep it comfortable. Energy prices in the US really need to skyrocket, it's the only way that people actually care about consuming less energy, and thus making everything more efficient. If you can run an AC all day for basically pennies, obviously that's gonna be the preferred choice.

EU here. Rolling shutters are very normal around here indeed. They insulate pretty well. On hot days with no AC, they do keep the house cool. However, there are a few downsides. Larger windows require huge shutters, which require a lot of force to pull up. Usually they are electric, but that increases the installation cost. But most of all: they’re depressing! On hotter days you basically turn your house into a bunker. I think that’s why on new houses outdoor rolling screens are winning against rolling shutters. You can still see the outside when they’re down, but they block most of the sunlight…

Funny you upload this video now. I was just talking to my mother about this. My favourite type of house, I am Australian, is called the Queenslander. It is nearly fully surrounded by a veranda, and designed to allow and promote passive cooling. I had the pleasure to live in one for a while, and while it still hot, Australia after all, it was amazing what it could do without electrical cooling. Southern US houses are not too far off what we traditionally did in Australia. Edit: I do need to say, don’t underestimate the power of a very heavy curtain in the summer. It won’t be as effective, but it is amazing the difference. In our house, an awning, with our roofs already overhanging our houses, and a heavy curtain, it can be 35°C out side and it will be comfortably cool inside. With our eaves a heavy curtain will lower it a lot. A heavy curtain alone will lower the temperate enough to be on the higher side of comfortable. The house I grew up in was from the 1960’s, and we only needed air conditioning if the temperatures reached over 45°C, which was two or three days a year where I live. The majority of summer is in the mid to upper 30’s, and a combination of either awnings or hyper aggressive eaves, with heavy curtains, we never touched our AC.

Yep, Southerner here. We traditionally build houses that are either easy to air out or are naturally breathable (cracker houses), and awnings and shutters were traditionally ubiquitous.

Utilities don't want to invest rate payer money into program options that can't get traction, and neither the builders nor the public are likely to embrace code requirements for something seen as an aesthetic choice - no matter how functional it might be. And a home with a half decent thermal envelope might see 300-400 kWh savings over a year, which at most power rates in the country means 15-20 years to pay back your investment on even a small $1,000 awning investment.

The motorized rollers provide an excellent opportunity to save additional energy actually, because system can be used way more consistently. My parents have a system installed that automatically extends & lowers the sun screens when there is a lot a incoming sun, but automatically raises them when the wind conditions require that to protect them (among some other variables, and a manual override is available). This makes them much more useful, you can leave them down/extended even when you leave the house and when you are not there, they will still work. It's also that much more convenient that you use them a lot more than if you have to drop and extend each one individually.

HVAC and Energy engineer here - commercial energy codes are fairly strict about glazing area and solar heat gain coefficients allowed in new construction and renovations. There's nothing explicit about requiring shading or overhangs, but its very widely known that external shading elements can have significant reduction on cooling loads. Residential construction is driven primarily by first cost and aesthetics. Only standards like Passivhaus or other net-zero home designs have requirements on external shading.

[@P_RO_]

Life-long building contractor here (including commercial) and I've never encountered "codes" requiring anything regards glazing area or solar heat gain. But I have seen it implemented and considered in the sizing of the HVAC system, and I've built some passive and active solar design elements into homes an buildings including one 'commercial' where the entire active part of the HVAC was one blower and two in-duct 'dampers' which routed the airflow to change between heating and cooling. Less than optimum siting of that one meant that additional heat was sometimes needed for worst conditions but the HVAC costs are about 15% of the same area using conventional construction techniques. Other than industrial construction where form follows function by necessity, all construction in the US is driven by aesthetics, and consideration of costs is in an inverse relationship to market value and position. Everything is based on "looks" and damn little consideration is given to anything else as long as you meet or beat the prices of 'comparables'.

Finally, someone mentioning Passive House. Even if not following the specifications to a T, there’s a to be gained from even some of the suggestions. Alec has already talked about heat pumps, insulation, and electrification. Now we’ve almost got building envelope covered with talk of awnings and windows. I’d love to see some more talk on how vernacular design should be more adapted in both urban and non-urban areas. A lot of people have mentioned their local structures with ventilation shafts, cross breezes, and cooling with trees and water in other comment chains. I think the big take away is that architects, builders, and developers should have greater contextual awareness when they design their buildings, but that might be asking a lot when it effectively reduces how much “mass production” can be implemented. Who wants to think semi-originally 5 times when you can just copy-paste at a fraction of the cost?

I don't think I've ever paid attention to awnings before except to note that they seem to mark older buildings. My partner recently moved to an old home that is exceptionally comfortable in summer when the windows are open. The cross breeze feels like a strong fan on high. And that's on days with low wind. I don't understand how it works but there's some kind of vacuum effect. Like awnings, we've definitely forgotten the advantage of passive cooling techniques. Great video! I'm glad I watched!

[@bassplayer137]

I work in the installation-branch, and one of the first things taught is: if you don't get the heat in your house/building (something blinders, curtains etc don't completly negate), you don't have to cool it out. Awnings are one of the best ways to keep the heat out and save a bunch of energy on cooling the space.

Do keep in mind, many homes used to be designed with an east half and a west half. As the sun rises, spend time in the west half, and as the day goes on, spend your day in the East half with an awning, warm, but totally shaded. It's an old method, but worked VERY well at my grandfather's home. And it got up to 125 on some summer days! It could be cooking 120 on the west side of the house, turning that part into an actual oven approaching 150. The east side with open doors and windows but closed screens allowed that side to stay at about 85. Very livable and doable and pleasant. Having many fruit trees in the yard allowed for berry bushes and grapes. Old techniques are so simple, yet so deliberate.

[@DanielinLaTuna]

In Los Angeles (and other US cities that were founded by Spanish colonists) there are no east-half and west-half, because the streets aren’t N/S-E/W grid. Instead, they are built at 45°, giving everyone a shady side as they travel. Trees were also mandated by the Spanish government.

3:10 In the Soviet period up to about the mid-1960s urban planning would involve planting a lot of trees near (about 5-10 meters) apartment blocs to keep them shaded and cool in the summer months and reduce noise from roads, railways, etc. Unfortunately now all this knowledge has been forgotten and our cities are being turned into hellscapes of a kind a Czechoslovak children's writer, Zdenek Miller, warned us about.

We have the exterior security roll up shutters on all of our windows. The people who owned the house previously installed them for security purposes. When we purchased the house, the previous owner told us that the shades were great for cooling the house down during the summer. My husband and I thought “yeah, sure.” Well, we have eaten those thoughts repeatedly over the last 10 years! Those security shades do block the heat from the sun. The windows stay cool and so do our rooms. They are fabulous! Definitely not as charming or attractive as the awnings (which I would love to have! They add so much charm to a house!) but, very affective at cooling the house! The shades that you showed in your clip were not closed all the way, they were still letting light in. When you close them down all the way, the light is completely blocked. My husband and I enjoy your show! Thank you for sharing the results of all of your thorough research on such fascinating topics!

Yep, we also have those. The space between the window and the shutter does indeed get quite hot, but since we have double glazing, that heat doesn't pass through the window much. Ours don't do anything for security though, from the outside you could just push them up... If we didn't live on the 3rd/4th floor of an apartment building :)

In Sweden Awnings are still popular, which makes sense as most houses do not have AC installed (we cannot really justify it with only 10 - 20 days when it is needed). We just replaced the old awnings on our house with new ones. Without awnings, our living room, with a south-facing window and an entire "window wall" towards west, becomes 5-6 °C warmer, even in the April-May sun. Our new awning covering the "window wall" is connected to a light and wind sensor and it works automatically.

I was born and raised in Minnesota so, when I first visited family in India, they were initially worried about how I’d deal with the heat, but the houses there are designed for it and it wasn’t really an issue. The concrete construction, granite or tile floors, shaded windows, and, when needed, those powerful ceiling fans, it was rarely an issue. Clothing also helps. It’s dry enough there that a cotton shirt worked really well. Not everything would translate. It’d be horrible to heat one of those homes in a Midwestern winter, and it’s humid enough here that cotton isn’t always ideal. But there are definitely lessons to be learned about designing for the climate.

I’m an architecture student living in the Southern US, so this comes up a lot in study. As a basic rule of thumb, shading windows is a percentage function, where blocking 50% of light reduces 50% of heat gain (roughly). So a translucent material or a material that dapples light (think perforated metal or shade through a tree) can have enormous benefits. If this is interesting to you I’d say have a look at some of the other options that are out there that do similar things, a favorite of mine is Fritted Glass, which has a ceramic paint on the glass to reflect light off of the windows. That’s kinda similar to your translucent glass awning idea. I get really excited about this stuff, so if it’s an interest of yours I’d love to see more about these topics from you

Here in Texas, the trend has been towards "Solar Screens", these mesh panels retrofit over the existing windows, and reflect much of the light at a certain angle, but if below that angle (for example in the winter when the sun is lower on the horizon), will allow the light to pass. It also allows the residents to look out with minimal blocking of their view, or even open the windows to let fresh air in. The only drawback is that the home from the outside has the windows looking like big, black squares, and the window details are lost.

Hi! Spanish Architect here, I have been working some time with climatic upgrades in buildings and there is a lot to learn and understand. Seeing where your content is leading, you may want to learn about "Passive House" or "Passivhaus", as a way in which the buildings themselves work to reduce the need for active cooling/heating. The main take is that there are different ways to adapt to different weathers depending on temperature, humidity, sun exposure and their change along the year. Not only are there better materials, but also the use of awnings, "european" blinds, exterior shading (trees or other buildings*), water (as a way to de-extreme temperature changes) and having different facades for each orientation (horizontal “briloleis” soth, vertical “brisoleis” east and west, and none north). There are a lot of case studies that one can learn from. In countries like Spain, it is very much studied and known, just because it is very much needed. *: Historic cities tend to have narrow streets in places where there is too much heat, to reduce the heat not only the buildings received, but also the streets.

My family stayed perfectly comfortable with an evaporative cooler on the roof. My mother grew up in Phoenix in the 1930s, when they didn't even have that. Instead they had cots on a screened-in sleeping porch where they soaked their sheets with water and let the natural evaporation cool them off enough to sleep.

I lived in Mesa, AZ (suburb of Phoenix) back in 2005-2008.
