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.

[@LeafofLifeWorld]

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

[@lm-pw9ul]

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.

[@JCR_cande]

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.

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.

[@LeafofLifeWorld]

​@@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.

[@LeafofLifeWorld]

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

[@eddyb2001]

Exactly it's all about the thermal mass and reducing heat gain.

[@markhathaway9456]

If they used CFL and LED lighting, it would remain cool.

[@HistoryOnTheLoose]

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.

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.)

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.

[@feedigli]

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.

Domes are more earthquake resistant and a lot stronger than a flat roof. Very informative and useful video, Leaf of Life.

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.

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 !

It makes me feel sad to think about the 10% of Americans who don’t have ac

[@Jonathan-jo2xu]

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.

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.

[@JoyPeace-ej2uv]

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.

[@RichardHarlos]

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.

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.

[@LeafofLifeWorld]

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.

[@feedigli]

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.

[@cenedraleaheldra5275]

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.

So, basically a chimney then. In Malaysia, we use a turbine ventilator, which allows hot air between the roof and ceiling to escape.

[@margaretjohnson4413]

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.

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.

[@LeafofLifeWorld]

​@@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.

[@maxhugen]

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.

[@Richard-me2pq]

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.

[@andyhorn6765]

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.

[@ATomRileyA]

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.

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.

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
