this is true but at the same time because the house has over hangs in front of the windows its actually creating an area of cool air in front of the house so even when you open the door and window you can feel a cool breeze as the heat from the top sucks in the cool air
At my place when it's 45°C outside, it's 50°C inside. The windows are facing West so they get direct sunlight in summer and get super hot starting from around 3pm and stays hot until late nights or early morning. Don't like to open windows because of dust, pollen and flies/insects. Some days can also get very humid.
Yes, I agree. Maintain all windows and doors closed when the highest temperatures, and open windows and the roof window at night to create natural ventilation. The hot air flows upwards, escape and force cool air to enter through the windows.
In the Middle East, they also use underground tunnels to have the air circulate further down, and get cooler, where there is water, so they have access to water, and cooler homes.
@@hundertwetter according to one of her comment, it wasn't used in this video (while making the video) and also it's a rented property and some foreigners might demand AC, many other houses don't have it though.
@@eddyb2001 Laws vary, but most important are structural integrity and safety. If those aren't violated, then it should be alright. Since those structure have been around a long time, it should be easy to make the case that they're plenty safe. Of course, the specialized construction techniques of the dome-builders might not be available everywhere. In those cases, there may have to be either another way of having the domes built properly or of adding strength to them.
kwa wrote, _"Ari temperatrure is what we use, not the temperature of the gound/floor surface."_ Perhaps it would benefit you to understand a bit more about thermodynamic. Ground, air, surface, material properties, etc., all contribute to the overall movement and storage of heat throughout a structure. Too many people oversimplify too many things in order to create an illusion that they *'know'* what they're talking about when, in fact, they do not.
@@RichardHarlosthere is more than one way to measure temperature, as long as thr two temperatures taken are at the same altitude we can compare the two.. " In meteorology, we commonly distinguish between air temperature (near the surface or in altitude),surface temperature, soil temperature and water temperature and temperature in altitude. In addition, it should be noted that temperature is highly dependent on altitude. On average, the air cools by about 1°C per 100m elevation increase. Therefore, it is important to know at which altitude the measuring station is located and at which height the temperature sensor is fixed. In this way, the altitude of the station and the height of the instrument relative to the ground can be considered correctly."
I grew up in California and visited many of the old Spanish missions there. Everything about the construction is designed to keep the buildings cool. They are usually painted white to reflect sunlight, and the walls are very thick and well insulated, which helps in preventing the heat of the sun from reaching the inside of the structure. The adobe bricks used to make the buildings, which are made with a cement mixed with straw, stay quite cool as well. The flooring inside is all made of stone, which also helps in staying cool, and the missions feature courtyards which are designed to maximize shade all day long. The windows are also built in a way so that the amount of sunlight coming in is minimized as well. I always noticed how cool it was inside those buildings. The downside is that they are, of course, quite dark inside.
Thats very true and is a design from Muslims brought to Spain, this house was using all these principles except an inner court yard. This particular house was quite light and bright due to the south facing windows but the windows had an over hang to prevent direct sunlight penetrating inside, so it still kept it cool
The California Missions were NOT built of cement and straw. They were built of adobe bricks cured in the sun. Not cement. The tiles were not stone, either. They were also manufactured on site from a clay based composite. Same as the roof tiles. The white color, while superior for heat reflecting, comes as a result of the plastering over the bricks. Adobe can last for generations, as long as it is kept dry - from above as well as laterally. The plastering served that purpose, especially in certain coastal California locations. The Missions weren't always white, either. Many buildings were painted a darker color, often a reddish due to ease of availability of iron oxide (why old barns were red) for a distance up the wall, then finished in a tan like color for the majority. The use of Adobe was not introduced by moorish influenced Spaniards, as there is pre-Columbian evidence of its use. I began as a Mission docent 30 years ago.
I PERSONALLY DO LIVE IN THE SONORAN DESERT and I HAVE A HOME BUILT IN THIS MANNER and IT DEFINTELY STILL REQUIRES A MINISPLIT AND EVEN WITH THE MINISPLIT SET AT 62 DEGREES, MY TEMPETATURE IS NEARLY 100 DEGREES AT NIGHT! I have a 12000BTU minisplit for only 176 sq ft of a Morroccan Dome Home AND STILL IT IS HOTTER THAN HELL
The buried culvert system works… but, going 4’ underground is the best way to go in any climate… only consideration is the land in that case… four feet underground and the temp is constant in the low 60’s… that’s why the culvert method works… research to earthship construction. I lived in Phoenix for 30 years… always wanted to try this… questioned how well it would work there, vs the high desert in which the earthship design was born.
The arab ones pull the air more underground to cool it off or by water or pools to cool it. With caliche I doubt you could do that without spending a fortune.
Its one element but having lived in a white building myself that alone is not enough, high ceilings and overhangs really are important because even with white walls if the windows face the sun, it will get very hot inside
@@LeafofLifeWorld We need home plans which use that solar heat for heating water and designs which also block sunlight where we want to live most. Add underground air flow for cooling or maybe a passive solar mass wall for storing heat for air warming at night. There are a lot of different passive elements which can be used. Practically NONE of U.S. houses use these. We're a commercially-driven place.
Lou Hoover designed Stanford University’s President Residence (SF Bay Area has a Mediterranean climate) incorporating many of the features in homes & buildings she saw in her lime living in Morocco. We need more of these types of building innovations, but earthquake safe.
No where in the San Francisco peninsula has a Mediterranean climate. A dome construction is also preferable in an earthquake because it lateral force is dissipated through a wide area.
Late Iranian Architect, Nader Khalili, proposed and experimented ‘cooking/firing’ these clay adobe buildings. He also proposed a gravel bed foundation. This combo would provide earthquake resistance! His children have been teaching his fascinating adobe techniques at their school “Cal Earth Foundation” in Southern California…
@@fairopenhonestx0275 I know. I read both his books Ceramic Houses and Racing Alone. He found an old English word derived from Farsi , “ Geltaftan” which means pretty much what his technique entails. In 2002, I finally got to meet him in Hesperia, California. He was explains the use of white wash as a coating for buildings. I told him that white paint made from lime.milk and vinegar was a better option for a dome. The paint is elastic and expands and at the same rate at which the dome dissipates heat. The color white reflects the light. However, the convexity of the dome refracts light which is much better. Sadly, within four years time he had died.
@@sexywarriorwomen put milk in a cauldron. Let it simmer. Put in the vinegar. Gently add the lime water. I am not talking about lime juice, but the mineral. Milk contains casein, a protein which when treated with vinegar acts as a plastic.
To really keep the house cool, build the entire house at least 2m underground. For walls facing the sun, put shades on the outside, not inside the windows. And shade the entire wall, not just the window.
The temperature is supposed to be measured in the shade, not on the ground that is being heated directly by the sun. There's going to be a big difference between sun and shade outside.
You can bet the alarmist are measuring black soil in full sun . Last year they touted water temps in a four foot deep back water at a marina The sea ice pack is at a twenty year high .
What else can be done to cool a house without conventional AC? Lots! If, during your construction, you're able to get use of a backhoe or digger, you can use it to dig a 1.5-2m(5-6ft) trench for 10-15m (30-50ft). Then you place a tunnel of rigid material down there, like concrete conduit. One end of the tunnel should end inside your home, on a lower level, and one end should terminate outside in a covered area protected from animals by mesh. The temperature down there should be notably lower than the daytime high temperature and you can use the air to cool your home either by pulling it in with a fan, or using thermal ventilation like in this dome. There also exist paints, that can be made in a garage lab, that can convert ambient heat into a specific wavelength of IR that our atmosphere is completely transparent to. What does this mean? It means that a surface coated in this paint can cool itself up to 10C (18F) IN DIRECT SUNLIGHT. It's not a huge amount of cooling, but it works all the time and can just be used as a nice, white paint. (It is fragile as a paint, and kinda expensive, so it will need a protective coating, but it still just sends almost 20F of heat zooming off into space without power.)
@@mapsvg Most of the one's I've seen have an underlayuer of permeable material like gravel or fill rock, a layer of some kind of gardening cloth, and the conduit itself has penetrations on its low side to allow drainage.
The current official highest registered air temperature on Earth is 56.7 °C (134.1 °F), recorded on 10 July 1913 at Furnace Creek Ranch, in Death Valley in the United States.
But also: "Official Temps" are like...Wet Bulb in the Shade, which is a *complete* crock. People get so pissy when you talk about Temps taken in the Sun as being fake temps. Bro....I am in the sun, not in the shade covered in water lol "Real Feel" Temp = Real Temp. And I got a Temp reading in Baghdad, Iraq of 160F from when I was there in 2003. Was just a random summer dat.
"There is no AC in this home." Well... Ten what is hanging on the wall above brown door in left upper corner in 7 m 56 sec of this document? Isn't this evaporizer unit of regular AC split system?
And there’s a ventilator on the other side on that picture as addition 😂 Omg, with all those gadgets you can build a room even in a form of poo and it would be cool enough 😂
This all makes so much sense. Roasting in a "modern" house when the ac condenser froze, and looking to see how the world survived with no AC. Thank you!!!
Those aren't new techniques..... Architecture that promotes airflow and natural cooling has been around for thousands of year. We stopped using them because of electric AC and heat.
Then we made a very poor choice indeed. So many areas of the planet, in particular large metropolitan areas, have built building and roads that are not designed to naturally regulate temperature. In doing this, we have only made our temperature regulation more difficult... and costly.
She's spoken several times throughout her video about so many previous cultures using their techniques. So I'm not sure why you're repeating her. You're exactly as smart as someone who paid attention.
117*F outside, 77*F inside Still not cool enough for me ! Under ground houses in my area maintain a 55*F temp year round so only a little heat needed in wintertime!
If the exterior is painted with the new cooling paint and the house walls are thicker for insulation, then you could achieve more passively. The exterior/under-house tunnels for cooling of air flow is also interesting (though perhaps hard to add after the house is built).
I hate to break it to you but at 6:19 in the video. That thing on the right side of the wall beside the light on the top of the wall. Is an air conditioning unit.
In Malaysia and Indonesia they use thatch roof with a vent near the top where all the heat escapes but rain cannot get in. These houses are not dome shaped but more rectangular. These traditional houses have no A/C at all just gentle cool breezes. The key I think is the vent near the top and not the shape.
I actually think the shape is more important. The traditional houses of Batak and Miningkabow people (sp? it's been a long time since I was there.) in Sumatra have a sway-back wooden or thatched roof with a large, screened vent at each end. The ridgeline also extends quite far beyond the vertical walls of the front and back facades, sheltering them and their porches from rain to a degree. Thus, viewed from either side, the roof resembles a square sail billowing in the wind, dipping lower in the middle and quite high at each end. So this creates a Venturi effect, where the breeze coming in the large vent at one end is compressed in the middle and then rushes out the vent on other end, pulling more air. And when there is no breeze, the warm air from inside is able to rise because of the upward-trending ridgeline, and the outflowing air creates a cooling airflow within. In a hot, humid environment like theirs, airflow is key to comfort.
Its there because in July and August is the rainy season and is humid, so maybe needed during that time, thats only some houses have this probably because it is a rented property and some foreigners demand ac. But it wasn't used in this video
That is not true, I live in the Sonora desert and have stayed in those house for vacation in May, June, July August and Sept, with out the mini split AC they are hot and miserable.
And yet, the fact remains that only 16% of Mexican homes have air-conditioning so... what exactly is your point? That they used a very nice house to illustrate their points, but that particular house has some A/C for extreme temperature incidents? How silly a counterpoint...
Same as the Temples in Thailand, very tall structures with high sloping roofs ending in a sharp point, the radiated heat doesn't get down to the floor so sitting there, very comfy, while outside very hot.
I live in middle east From 47 outside to 24 inside is theoretically impossible without an AC We have 36000 btu AC and the temperature outside is 44 we can not go beyond 28 inside with AC on
Remote rural off grid here down under , have embarked on an extension using packed Earth car and truck tires got the idea from Mexico where they build such things. Using the peak of the building as a flow through of hot air and having tubing at just above ground level , created the same as a cave cool air gets drawn in. Also painted the roof of the house, workshop ect with eco paint , its very white and reflects up to 80 percent of UV., and around seventy percent of heat ... 45 degrees outside main core of the house is around 30 or so, works.
Come to Mexico Sonora or Guadalajara there you'll find people skilled to do this, jus be sure about because not everyone is that skilled. Takes years to become a master
AC has been a game changer for me. I live in England where houses are built for cold and wet rather than hot and dry with my house having tonnes of insulation in the walls and roof and most people have central heating but don’t have air conditioning. In Summer we often surpass 35C and the inside of my house is like a greenhouse. 😭🔥 bought a little mobile air conditioner after a summer of almost 40C heat and it’s made such a difference 😍
That's one of the things people forget, you don't have to cool your entire home, just cooling one room with a portable AC is enough, we have central AC but I have a small window unit installed in our bedroom, we use that at night instead of running the central air while we sleep
Domes are more earthquake resistant and a lot stronger than a flat roof. Very informative and useful video, Leaf of Life. I was in some strong earthquakes and saw a lot of flat roof buildings that collapsed. In fact I often wondered why churches with domes in summer were very cool compared to the temperatures outside, I just thought it was because they were large and dark, without many windows but actually they often had a lot of windows. Hopefully more people will try start building domes to cool their homes down naturally instead of using Air con which heats up the temperatures outside houses, offices and apartment buildings and can get dirty quickly and harbor some nasties. I always feel bad when I get an Uber driver on hot days and they have strong A.C. and a recurring cough or some kind of nasal problem, its so sad their job is making them sick. I also had a job with a horrible AC and no one wanted to open the window to get fresh air. I constantly had headaches and low energy. Great video yet again, your recent videos have been really good actually, much love Leaf of Life you seem to be working really hard on these videos they must be a lot of work, I hope millions and millions of people see this video and are inspired to build domes houses and use less AC which is very bad for the environment! Thanks for sharing this, the house look really nice and comfortable as well, I would LOVE to live there. BTW The world will be a better healthier place if everyone watches your videos i think sometimes! REALLY Great video once again Leaf of Life!
Correct me if I'm wrong, but I thought I saw a wall unit inside that is part of a split AC system. Or was that for heating? The measured difference was amazing though.
cooling a home naturally is a lot easier in hot dry climates, in places where it's 90f and humid you can't escape the humidity without AC, even 70f at night but high humidity is very uncomfortable and hard to sleep in
This house is actually built incorrectly, there is supposed to be a pit/cellar in the middle of the room to store food/ice throughout the year, kind of an important feature to leave out as refrigeration and hot water are typically the second largest consumers of electricity in the household.
Amazing!! You all did a great job of explaining this. I hope that more people can use this technology in the many areas of the world that need this now. Thank you for the great work you're doing. 😇
I live next to a sizeable pond and my AC is to pump carefully strained bottom-of-pond water through a fabricated A-Coil in my furnace. The water is returned to the top of the pond after use. The strainers require a bit of cleaning from time to time - but hey no compressor or freon !
Interesting at 4 minutes 15 seconds they show a shot of the room and what looks like a mini split shows on the right side. You can also see a fan in the corner.
@@LeafofLifeWorld the particular AC units shown in the video do not act as heaters. they solely act as AC. and these houses can never go sub 80f/26C without the us of an AC
It is sad that 90% of Americans believe they need AC. For thousands of years, we managed just fine without it. I spent the first 30 years of my life without it. Then, I moved somewhere where it was everywhere-in the house, in the car, at work. I too began to need it. It’s incredible how hot everything became. Additionally, in the winter, everything seemed colder, even though it was warmer in the winter and not much hotter in the summer. Interestingly enough, the area where I reside requires black asphalt roofs, which is absolutely ridiculous. It should be illegal to have black roofs in the South! Everybody loses except for the energy companies.
You can also use Ivy or Bougainvillea to grow along your walls, preventing your hous to hit direct sunlight. This will look pretty, but also keep your walls from heating up, keeps them cooler by 5-10 C•. You can also gather dew & rain runoff in a cistern, to water them. Also, you can use 10-20m burried piping system, which you can open during nights and close during the day, to let airflow pass through.
I lived in Phoenix for last 36 years and electric power has gotten lot more expensive. The key to saving money is buy an energy rated home that is insulated to a standard. Also install a high seer mini-split system that only cools rooms you want cool you can adjust each room.
Actually it gets just as hot in the shade in those locations. I lived in AZ and even in the shade it is miserably hot. You need to get almost underground into caves to get noticeably cooler or into a house not just shade.
Mrb wrote, _"Measuring temperature in direct sun is dumb..."_ Perhaps you didn't stop to realize that the buildings are in direct sun, and therefore such measurements are relevant to the point of the video, which is to illustrate how buildings (which exist in the direct sun), located in the hottest places on earth (deserts), are able to stay cool without the use of modern electrical solutions.
@@RichardHarlos Then the thermometer needs to be the same color, oriented the same to the sun and insulated exactly the same, exposed for same time. *Measuring temp in the sun is DUMB.* She was pretending to take *air temp* and anything else is meaningless.
@@Mrbfgray Let's get down to the core issue that you obviously have: what **exactly** is the margin of error here, and why does it matter so much to you that you feel that insulting people is the best reply you can muster?
The white paint is a major factor as well. I experimented on a south facing outside wall, and white paint was 20-30 deg F cooler than a medium (more than 50% reflective) blue paint. Most of the heat inside was coming through the roof, though, which was 3 tab asphalt shingles. I wish I could cover the roof with something white. It should be noted that not all white paints are equal, as only some reflect infrared radiation, and half the solar radiation hitting the Earth's surface is in the infrared.
they only use it in july and august when the climate changes from dry to humid since its the rainy season. we didnt use the split ac system in the making in this video
It's easy to build a house against heat or against cold, but the really hard thing is to build a 4 season house. We in Europe don not use these methods, because we have very cold winters and very hot summers.
My understanding is that ground temperatures 1-2 meters deep are pretty consistently 13-18 C , year round, in most of the temperate latitudes. So, using earth tubes as many have suggested, is not a complete, stand-alone solution, but would definitely moderate extremes, reducing the heating/cooling needs to a level that, in cooperation with other methods, could be handled sustainably, without resorting to a/c, or fossil fuel heating. A lot of European cities use sun shades over their narrow streets in summer, which really helps. Again, not perfect, but much nicer than the wide, baking asphalt of American car-based streets.
stunning yet sad that human know this knowledge yet the power companies and such wealth people want people to continue to pay their power bills. Here in Australia I thought solar power would assist my bill paying to be lower. But No those Power company have been adding new ways of charging people who use none of there electricity.. They invent fees. Any fees they can think of. Initital my power bill was a low 20 or 3o dollars now it is up to $100 or more just in fees.
Variable insulation (shutters for windows, doors, walls and roof). Opened during night. Natural ventilation from north side. If the floor if not insulated from ground is cool enough. It works if there is a difference of temperatures between day and night. In summer, in my little wooden house, 80 sqm, outside 31 C, inside 18 C with closed shutters. Without cooking.
You mean tactical ventilation not "tactful. " and its not innovative either it is ancient . The word innovative comes from the Latin Nova meaning New. There are various forms of building tactical ventilation depending on the prevailing winds and building materials available. What you called an oculus is actually a Lantern Oculus means eye in Latin.
they have alot of earthquakes in Mexico and they still use them because arches and domes are strong, yes we didnt go into the details of that in this video because we are talking about temperature
I'm from Mexico City where a lot of earthquakes happen each year. Strong earthquakes don't happen all over the country, not 100% sure but as far as I know at the north of México they don't feel those strong movements as compare to the south of the country. Also, despite the phenomenon here in the city we have a big cathedral with hugo domes that have resist strong earthquakes over decades. So, as she says, this type of architecture can resist. Great content as always, keep up with this incredible work you guys are doing!!!
@@LeafofLifeWorld Oh.. Well it would be a good mention since one might wonder why this isn't everywhere... and that seemed like a glaring reason "could be why" This are fantastic news Air conditioning is always the biggest electricity spender per household. I don't see why this method shouldn't be everywhere where its hot in that case.
@@Poske_Ygodomes are everywhere, every church, mosque and many government buildings all around the world. alot of domes are also hidden under flat roofs so you don't see them. I think they are not used as much in the states because alot of houses are build from wood and wouldn't be able to support this kind of structure, its also probably expensive to hire the skilled craftsman to do this in the US but in Mexico its more affordable, domes are also regularly used in Africa, middle east and Mediterranean basin still.
There are many useful ideas to help make a dwelling more livable in climatic extremes. But too often they come with an upfront price tag that people can't afford. I previously owned a double brick home with a tile roof in Australia that was way cooler inside, had no AC, just ceiling fans. But that form of construction is considerably more expensive than common alternatives.
Deserts have no humidity.Therefore, Southern states have high humidity rates of 80% on top of high temperatures on top of high pollen counts, mold, mildew, fungus, pick up truck dust and dirt. Sit in a wet sauna and watch black mold climb the walls; then tell us how much Americans spend on air conditioning and electricity! Please lady, I would like to hear about how Sonora's are more superior to Americans!
Sonoran Desert is also part of the USA as explained in video, Mexican are also Americans since the country exists in "The Americas" we just reading the stats nobody said anything about better or worse
I saw many of these incredible domed structures in San Miguel Allende in northern central Mexico including many ancient as well as modern constructions. Having built brick domes myself I was struck by just how shallow these domes can be built as normally the bigger the space the higher the dome needs to be, whereas these domes do not have to be, and what is more unlike traditional domes they do not need to be built over a plan with a perfect geometry of equal sides ... Ie over a square, hexagon, octagon, circle etc but can be built over rectangular spaces. In the one old church and an old ministry I saw there they had used stones to build the "domed" type structures, yet the height of diagonal curved vaulted "domed" geometry were so slight that the ceiling created underneath was more akin to flat slabs than to a dome..the technique is so simple yet absolutely ingenious.
Important thing to notice the satellites measured ground temp not air temperature, just a little sneaky trick to pretend its hotter than it is. The old hottest temperatures were recorded with air temp. Understand that you can fry an egg on the ground but you cannot do that with the air temp in the same place.
Great video! Building dome homes like this could be a great solution for living in hot climates. Another great solution for hot and extreme climates is living (and growing food) underground, such as earthships, hobbit holes, and the Forestiere Underground Gardens in Fresno, California.
Thank you for producing the video. It's well done and informative. More people need to see the flaws in conventional United States construction practices. All you need to do now is add this ultra-white paint developed by researchers at Purdue University. This paint is designed to reflect a significant portion of sunlight and radiate infrared heat away from surfaces, thereby cooling them.
🏞 *"Cool" and informative report on ventilated domed roofing!* Thanks for showcasing the reasoning behind the aesthetics, design, and effectiveness of this ancient [yet totally effective and relevant] technique. I particularly like the Mexican spin on brick layout, which looks beautiful and can save a lot of money and avoid unnecessary energy use. My one concern is in regard to earthquakes, however I have to wonder if modern techniques such as wood framing for flexibility (see Japanese quake-resistant architectural methods) could be incorporated to add resilience. _Thank you for producing this informative video, and taking the time to visit homes, and share the knowledge. Keep up the great work!_ ☀
In California some pay over $1346 per MONTH for electricity due to Gov. Newsom's appointed Public Utility Commission allowing the electric companies to reap Billions in profits.
It's surprising to see a drop of 23 deg c. in Southern part of India we treat rcc roof (weathering course)with 5inches of broken bricks(surki) with lime and lay pressed clay tiles and paint it white. despite all these efforts temp diff is hardly 10 deg deg C -42deg c outside to 32 deg c inside
Time to reconsider the plan. It may be the roof shade, created from the walls around the top. It may be the kind of paint. It may be the design of the interior of the dome.
Seems like many of us could be applying these techniques, and saving a great deal of energy and expenditure. Am not sure though about my local building codes and how much of this type of construction would be approved.
or build underground house. Makes a house with a pretty much unchangeable temperature, but always cold enough. So only depends on the heating to get the temperature you want. There have been underground citys in areas like this.
Does anyone else see the mini split unit above the wooden arched door in the living room? Pretty cool design, but the home definitely has electric powered AC.
Here is solution for you guys for those who live in less humid areas have a water storage tank in ground and use an desert cooler water storage under ground can make water at 20-25 deg cooler and never open window in day time only. Open when sun has set you should wait for 1-2 hours use curtain and close them when sun rises and fill your cooler tank at night when sun is about to set if its a concrete tank you made to store your water. And if you are in middle of buliding your home then use windcatchers that more effective most of the hot air in your room bump into. Your roof so make some kind of chimeny there. Now for guys with high humidity use dehumidifiers or bulid some water storage inside your living room it can act as pool as well
Bóveda de catalán my mother was the first person in La Paz to have one built. Unfortunately a thief tried to break in and knocked a brick out of place and the roof collapsed.

Pro tip: When it's 25 C° inside and 45 C° outside, don't open the doors and windows.
Open everything at night, and close them in mid-morning.
this is true but at the same time because the house has over hangs in front of the windows its actually creating an area of cool air in front of the house so even when you open the door and window you can feel a cool breeze as the heat from the top sucks in the cool air
At my place when it's 45°C outside, it's 50°C inside. The windows are facing West so they get direct sunlight in summer and get super hot starting from around 3pm and stays hot until late nights or early morning. Don't like to open windows because of dust, pollen and flies/insects. Some days can also get very humid.
Yes, I agree. Maintain all windows and doors closed when the highest temperatures, and open windows and the roof window at night to create natural ventilation. The hot air flows upwards, escape and force cool air to enter through the windows.
Pro tip : move to a cooler location
Night time temps in the region during summer don't fall below 35C.
In the Middle East, they also use underground tunnels to have the air circulate further down, and get cooler, where there is water, so they have access to water, and cooler homes.

Perhaps it would benefit you to understand a bit more about thermodynamic. Ground, air, surface, material properties, etc., all contribute to the overall movement and storage of heat throughout a structure. Too many people oversimplify too many things in order to create an illusion that they *'know'* what they're talking about when, in fact, they do not.
@@RichardHarlosthere is more than one way to measure temperature, as long as thr two temperatures taken are at the same altitude we can compare the two..
"
In meteorology, we commonly distinguish between air temperature (near the surface or in altitude),surface temperature, soil temperature and water temperature and temperature in altitude.
In addition, it should be noted that temperature is highly dependent on altitude. On average, the air cools by about 1°C per 100m elevation increase. Therefore, it is important to know at which altitude the measuring station is located and at which height the temperature sensor is fixed. In this way, the altitude of the station and the height of the instrument relative to the ground can be considered correctly."
I grew up in California and visited many of the old Spanish missions there. Everything about the construction is designed to keep the buildings cool. They are usually painted white to reflect sunlight, and the walls are very thick and well insulated, which helps in preventing the heat of the sun from reaching the inside of the structure. The adobe bricks used to make the buildings, which are made with a cement mixed with straw, stay quite cool as well. The flooring inside is all made of stone, which also helps in staying cool, and the missions feature courtyards which are designed to maximize shade all day long. The windows are also built in a way so that the amount of sunlight coming in is minimized as well. I always noticed how cool it was inside those buildings. The downside is that they are, of course, quite dark inside.
Thats very true and is a design from Muslims brought to Spain, this house was using all these principles except an inner court yard. This particular house was quite light and bright due to the south facing windows but the windows had an over hang to prevent direct sunlight penetrating inside, so it still kept it cool
Exactly it's all about the thermal mass and reducing heat gain.
If they used CFL and LED lighting, it would remain cool.
The California Missions were NOT built of cement and straw. They were built of adobe bricks cured in the sun. Not cement.
The tiles were not stone, either. They were also manufactured on site from a clay based composite. Same as the roof tiles.
The white color, while superior for heat reflecting, comes as a result of the plastering over the bricks. Adobe can last for generations, as long as it is kept dry - from above as well as laterally. The plastering served that purpose, especially in certain coastal California locations.
The Missions weren't always white, either. Many buildings were painted a darker color, often a reddish due to ease of availability of iron oxide (why old barns were red) for a distance up the wall, then finished in a tan like color for the majority.
The use of Adobe was not introduced by moorish influenced Spaniards, as there is pre-Columbian evidence of its use.
I began as a Mission docent 30 years ago.

Are you in or near a city? Surrounded by concrete of asphalt? I’m trying to learn so asking with respect
The buried culvert system works… but, going 4’ underground is the best way to go in any climate… only consideration is the land in that case… four feet underground and the temp is constant in the low 60’s… that’s why the culvert method works… research to earthship construction. I lived in Phoenix for 30 years… always wanted to try this… questioned how well it would work there, vs the high desert in which the earthship design was born.
The arab ones pull the air more underground to cool it off or by water or pools to cool it. With caliche I doubt you could do that without spending a fortune.

Lou Hoover designed Stanford University’s President Residence (SF Bay Area has a Mediterranean climate) incorporating many of the features in homes & buildings she saw in her lime living in Morocco. We need more of these types of building innovations, but earthquake safe.
No where in the San Francisco peninsula has a Mediterranean climate. A dome construction is also preferable in an earthquake because it lateral force is dissipated through a wide area.
Late Iranian Architect, Nader Khalili, proposed and experimented ‘cooking/firing’ these clay adobe buildings. He also proposed a gravel bed foundation. This combo would provide earthquake resistance!
His children have been teaching his fascinating adobe techniques at their school “Cal Earth Foundation” in Southern California…
@@fairopenhonestx0275 I know. I read both his books Ceramic Houses and Racing Alone. He found an old English word derived from Farsi , “ Geltaftan” which means pretty much what his technique entails. In 2002, I finally got to meet him in Hesperia, California. He was explains the use of white wash as a coating for buildings. I told him that white paint made from lime.milk and vinegar was a better option for a dome. The paint is elastic and expands and at the same rate at which the dome dissipates heat. The color white reflects the light. However, the convexity of the dome refracts light which is much better. Sadly, within four years time he had died.
@@estebancorral5151do you have a recipe for that paint to share?
@@sexywarriorwomen put milk in a cauldron. Let it simmer. Put in the vinegar. Gently add the lime water. I am not talking about lime juice, but the mineral. Milk contains casein, a protein which when treated with vinegar acts as a plastic.
To really keep the house cool, build the entire house at least 2m underground.
For walls facing the sun, put shades on the outside, not inside the windows. And shade the entire wall, not just the window.
or just build a cave like open out side basement with a vent window it the top
We built with double stud R-40 foam filled walls and R-60 in the ceiling.
The temperature is supposed to be measured in the shade, not on the ground that is being heated directly by the sun. There's going to be a big difference between sun and shade outside.
You can bet the alarmist are measuring black soil in full sun . Last year they touted water temps in a four foot deep back water at a marina The sea ice pack is at a twenty year high .
What else can be done to cool a house without conventional AC? Lots!
If, during your construction, you're able to get use of a backhoe or digger, you can use it to dig a 1.5-2m(5-6ft) trench for 10-15m (30-50ft). Then you place a tunnel of rigid material down there, like concrete conduit. One end of the tunnel should end inside your home, on a lower level, and one end should terminate outside in a covered area protected from animals by mesh. The temperature down there should be notably lower than the daytime high temperature and you can use the air to cool your home either by pulling it in with a fan, or using thermal ventilation like in this dome.
There also exist paints, that can be made in a garage lab, that can convert ambient heat into a specific wavelength of IR that our atmosphere is completely transparent to. What does this mean? It means that a surface coated in this paint can cool itself up to 10C (18F) IN DIRECT SUNLIGHT. It's not a huge amount of cooling, but it works all the time and can just be used as a nice, white paint. (It is fragile as a paint, and kinda expensive, so it will need a protective coating, but it still just sends almost 20F of heat zooming off into space without power.)

Those aren't new techniques..... Architecture that promotes airflow and natural cooling has been around for thousands of year. We stopped using them because of electric AC and heat.
Then we made a very poor choice indeed. So many areas of the planet, in particular large metropolitan areas, have built building and roads that are not designed to naturally regulate temperature. In doing this, we have only made our temperature regulation more difficult... and costly.
@@RichardHarlos You're absolutely correct.

That sounds interesting. What area are you referring to? I'd like to learn more.
Sounds like Coober Pedy. Limestone is wonderful stuff.
If the exterior is painted with the new cooling paint and the house walls are thicker for insulation, then you could achieve more passively. The exterior/under-house tunnels for cooling of air flow is also interesting (though perhaps hard to add after the house is built).
Depends on the humidity. 77 @ 15% humidity is more comfortable than 72 degrees at high humidity.
4:19 I am sure the red brick dome is not uniquely Mexican but a Spanish boveda ceiling or Catalan vault ceiling used as far back as Ancient Rome.
I hate to break it to you but at 6:19 in the video. That thing on the right side of the wall beside the light on the top of the wall. Is an air conditioning unit.
🤣 I saw that
In Malaysia and Indonesia they use thatch roof with a vent near the top where all the heat escapes but rain cannot get in. These houses are not dome shaped but more rectangular. These traditional houses have no A/C at all just gentle cool breezes. The key I think is the vent near the top and not the shape.
I actually think the shape is more important. The traditional houses of Batak and Miningkabow people (sp? it's been a long time since I was there.) in Sumatra have a sway-back wooden or thatched roof with a large, screened vent at each end. The ridgeline also extends quite far beyond the vertical walls of the front and back facades, sheltering them and their porches from rain to a degree. Thus, viewed from either side, the roof resembles a square sail billowing in the wind, dipping lower in the middle and quite high at each end. So this creates a Venturi effect, where the breeze coming in the large vent at one end is compressed in the middle and then rushes out the vent on other end, pulling more air. And when there is no breeze, the warm air from inside is able to rise because of the upward-trending ridgeline, and the outflowing air creates a cooling airflow within. In a hot, humid environment like theirs, airflow is key to comfort.
@@feedigli TY. Also humid area, this designer: kotaronishiki

Using the peak of the building as a flow through of hot air and having tubing at just above ground level , created the same as a cave cool air gets drawn in. Also painted the roof of the house, workshop ect with eco paint , its very white and reflects up to 80 percent of UV., and around seventy percent of heat ... 45 degrees outside main core of the house is around 30 or so, works.
Well done!

AC has been a game changer for me.

Domes are more earthquake resistant and a lot stronger than a flat roof. Very informative and useful video, Leaf of Life. I was in some strong earthquakes and saw a lot of flat roof buildings that collapsed. In fact I often wondered why churches with domes in summer were very cool compared to the temperatures outside, I just thought it was because they were large and dark, without many windows but actually they often had a lot of windows. Hopefully more people will try start building domes to cool their homes down naturally instead of using Air con which heats up the temperatures outside houses, offices and apartment buildings and can get dirty quickly and harbor some nasties. I always feel bad when I get an Uber driver on hot days and they have strong A.C. and a recurring cough or some kind of nasal problem, its so sad their job is making them sick. I also had a job with a horrible AC and no one wanted to open the window to get fresh air. I constantly had headaches and low energy. Great video yet again, your recent videos have been really good actually, much love Leaf of Life you seem to be working really hard on these videos they must be a lot of work, I hope millions and millions of people see this video and are inspired to build domes houses and use less AC which is very bad for the environment!

Correct me if I'm wrong, but I thought I saw a wall unit inside that is part of a split AC system. Or was that for heating? The measured difference was amazing though.
cooling a home naturally is a lot easier in hot dry climates, in places where it's 90f and humid you can't escape the humidity without AC, even 70f at night but high humidity is very uncomfortable and hard to sleep in
If that house is so cool, why was there an outdoor AC unit?
Where was it?
This house is actually built incorrectly, there is supposed to be a pit/cellar in the middle of the room to store food/ice throughout the year, kind of an important feature to leave out as refrigeration and hot water are typically the second largest consumers of electricity in the household.

You can also use Ivy or Bougainvillea to grow along your walls, preventing your hous to hit direct sunlight. This will look pretty, but also keep your walls from heating up, keeps them cooler by 5-10 C•. You can also gather dew & rain runoff in a cistern, to water them.
Also, you can use 10-20m burried piping system, which you can open during nights and close during the day, to let airflow pass through.

Measuring temp in direct sun is dumb and I'm done at that point, that's a measurement of how hot THINGS get in the sun, not air temp.

The white paint is a major factor as well. I experimented on a south facing outside wall, and white paint was 20-30 deg F cooler than a medium (more than 50% reflective) blue paint. Most of the heat inside was coming through the roof, though, which was 3 tab asphalt shingles. I wish I could cover the roof with something white. It should be noted that not all white paints are equal, as only some reflect infrared radiation, and half the solar radiation hitting the Earth's surface is in the infrared.
That is soooo true

they only use it in july and august when the climate changes from dry to humid since its the rainy season. we didnt use the split ac system in the making in this video
It's easy to build a house against heat or against cold, but the really hard thing is to build a 4 season house.
We in Europe don not use these methods, because we have very cold winters and very hot summers.
My understanding is that ground temperatures 1-2 meters deep are pretty consistently 13-18 C , year round, in most of the temperate latitudes. So, using earth tubes as many have suggested, is not a complete, stand-alone solution, but would definitely moderate extremes, reducing the heating/cooling needs to a level that, in cooperation with other methods, could be handled sustainably, without resorting to a/c, or fossil fuel heating.
A lot of European cities use sun shades over their narrow streets in summer, which really helps. Again, not perfect, but much nicer than the wide, baking asphalt of American car-based streets.

So, basically a chimney then. In Malaysia, we use a turbine ventilator, which allows hot air between the roof and ceiling to escape.
You mean tactical ventilation not "tactful. " and its not innovative either it is ancient . The word innovative comes from the Latin Nova meaning New.

@@LeafofLifeWorld your point is still irrelivent modern experts and scientists know full well how they work and are not baffled
3:54 the ac on the left: whelp i don't exist
Ehm earthquake into a brick falling on your head.. SO i ENDED UP DISSAPPOINTED..
they have alot of earthquakes in Mexico and they still use them because arches and domes are strong, yes we didnt go into the details of that in this video because we are talking about temperature
I'm from Mexico City where a lot of earthquakes happen each year. Strong earthquakes don't happen all over the country, not 100% sure but as far as I know at the north of México they don't feel those strong movements as compare to the south of the country. Also, despite the phenomenon here in the city we have a big cathedral with hugo domes that have resist strong earthquakes over decades. So, as she says, this type of architecture can resist.
Great content as always, keep up with this incredible work you guys are doing!!!

Oh.. Well it would be a good mention since one might wonder why this isn't everywhere... and that seemed like a glaring reason "could be why"
This are fantastic news
Air conditioning is always the biggest electricity spender per household.
I don't see why this method shouldn't be everywhere where its hot in that case.
@@Poske_Ygodomes are everywhere, every church, mosque and many government buildings all around the world. alot of domes are also hidden under flat roofs so you don't see them. I think they are not used as much in the states because alot of houses are build from wood and wouldn't be able to support this kind of structure, its also probably expensive to hire the skilled craftsman to do this in the US but in Mexico its more affordable, domes are also regularly used in Africa, middle east and Mediterranean basin still.
There are many useful ideas to help make a dwelling more livable in climatic extremes. But too often they come with an upfront price tag that people can't afford. I previously owned a double brick home with a tile roof in Australia that was way cooler inside, had no AC, just ceiling fans. But that form of construction is considerably more expensive than common alternatives.
Deserts have no humidity.Therefore, Southern states have high humidity rates of 80% on top of high temperatures on top of high pollen counts, mold, mildew, fungus, pick up truck dust and dirt. Sit in a wet sauna and watch black mold climb the walls; then tell us how much Americans spend on air conditioning and electricity! Please lady, I would like to hear about how Sonora's are more superior to Americans!
Sonoran Desert is also part of the USA as explained in video, Mexican are also Americans since the country exists in "The Americas" we just reading the stats nobody said anything about better or worse
Did not have to say it! You implied it!
I saw many of these incredible domed structures in San Miguel Allende in northern central Mexico including many ancient as well as modern constructions.
Having built brick domes myself I was struck by just how shallow these domes can be built as normally the bigger the space the higher the dome needs to be, whereas these domes do not have to be, and what is more unlike traditional domes they do not need to be built over a plan with a perfect geometry of equal sides ... Ie over a square, hexagon, octagon, circle etc but can be built over rectangular spaces.
In the one old church and an old ministry I saw there they had used stones to build the "domed" type structures, yet the height of diagonal curved vaulted "domed" geometry were so slight that the ceiling created underneath was more akin to flat slabs than to a dome..the technique is so simple yet absolutely ingenious.
Important thing to notice the satellites measured ground temp not air temperature, just a little sneaky trick to pretend its hotter than it is. The old hottest temperatures were recorded with air temp.
Understand that you can fry an egg on the ground but you cannot do that with the air temp in the same place.
There’s a big fucken A/C unit right in the middle of the wall It’s called a split in Mexico.
I like that shaving brush microphone that she's using!
Reminds me of the dome/Firmament over our stationary Plane realm/world we live in.
God really is the master designer.
Great video! Building dome homes like this could be a great solution for living in hot climates. Another great solution for hot and extreme climates is living (and growing food) underground, such as earthships, hobbit holes, and the Forestiere Underground Gardens in Fresno, California.
Thank you for producing the video. It's well done and informative. More people need to see the flaws in conventional United States construction practices.
All you need to do now is add this ultra-white paint developed by researchers at Purdue University. This paint is designed to reflect a significant portion of sunlight and radiate infrared heat away from surfaces, thereby cooling them.
🏞 *"Cool" and informative report on ventilated domed roofing!* Thanks for showcasing the reasoning behind the aesthetics, design, and effectiveness of this ancient [yet totally effective and relevant] technique. I particularly like the Mexican spin on brick layout, which looks beautiful and can save a lot of money and avoid unnecessary energy use. My one concern is in regard to earthquakes, however I have to wonder if modern techniques such as wood framing for flexibility (see Japanese quake-resistant architectural methods) could be incorporated to add resilience. _Thank you for producing this informative video, and taking the time to visit homes, and share the knowledge. Keep up the great work!_ ☀
Well, i saw an airconditioning system installed. Thats why its cooler insided there.
3:54 split unit air conditioning right over the door.
In California some pay over $1346 per MONTH for electricity due to Gov. Newsom's appointed Public Utility Commission allowing the electric companies to reap Billions in profits.
Funny, I was just leaving a similar reply to a comment right above yours. Didn't even see this until after. Yep.
It's surprising to see a drop of 23 deg c. in Southern part of India we treat rcc roof (weathering course)with 5inches of broken bricks(surki) with lime and lay pressed clay tiles and paint it white. despite all these efforts temp diff is hardly 10 deg deg C -42deg c outside to 32 deg c inside
Time to reconsider the plan. It may be the roof shade, created from the walls around the top. It may be the kind of paint. It may be the design of the interior of the dome.
Seems like many of us could be applying these techniques, and saving a great deal of energy and expenditure. Am not sure though about my local building codes and how much of this type of construction would be approved.
Your data doesn’t translate if temperature is not stated in Fahrenheit.
Very confusing but I think she means the surface temperature while we are accustomed to discussing in terms of air temperature.
When she put the thermometer down next to the sand, she is taking the temperature next to the sand which will be much hotter than the air above.
or build underground house. Makes a house with a pretty much unchangeable temperature, but always cold enough. So only depends on the heating to get the temperature you want.
There have been underground citys in areas like this.
Wow, I live in a desert in North Western India, we have ancient domed clay houses, now I know why
Does anyone else see the mini split unit above the wooden arched door in the living room? Pretty cool design, but the home definitely has electric powered AC.
Very interesting. Thank you.
Here is solution for you guys for those who live in less humid areas have a water storage tank in ground and use an desert cooler water storage under ground can make water at 20-25 deg cooler and never open window in day time only. Open when sun has set you should wait for 1-2 hours use curtain and close them when sun rises and fill your cooler tank at night when sun is about to set if its a concrete tank you made to store your water. And if you are in middle of buliding your home then use windcatchers that more effective most of the hot air in your room bump into. Your roof so make some kind of chimeny there. Now for guys with high humidity use dehumidifiers or bulid some water storage inside your living room it can act as pool as well
the dome structures are not the only ones keeping kool ... the marble on the floor also keeps the temperature low
Thats right!
You can see a mini split air conditioner in that house
Bóveda de catalán my mother was the first person in La Paz to have one built. Unfortunately a thief tried to break in and knocked a brick out of place and the roof collapsed.
Really?
Try to find someplace using this technique where the humidity isn't super low.
Good luck!
Your videos give my dreams hope. You make my heart and soul smile.
One day I'm going to build my home with the ideas you've shared.
I'm so grateful for your passion and your work.
Thank you and your team.
Go for it!
Excellent ideas !
