Good, solid, practical design work! About the double roof, this idea has been around for centuries, many cultures have figured it out. I've seen it done with desert tents, a large tarp spaced above the tent. Around forty years ago there was a medical office complex in Tucson, Arizona USA that did this with a stressed concrete roof above multiple independent single story buildings. It looked like a huge tent on multiple poles. The roof was on tall pillars, at least a ten foot clear space of free moving air above the buildings. The roof was large enough that the sun never touched the building walls. I was there for a dental appointment on a miserable day in August, temperature over 100F, and walking under that high roof the air was easily 15F cooler. Sadly, the complex lost the battle to modernization and real estate inflation. It was all torn down and a big ugly multi-story tower was built.

When people talk about "smart buildings", they often mean buildings with lots of sensors , electronics and complicated systems to regulate conditions inside. But truly smart buildings begin with designing a building so it doesn't need all of that or at least most) by placing relative to the sun, providing shae, using materials that absorb or release heat as necessary. In this sense this school is a particularly smart building

I live in the desert southwest near the border with Mexico, and every year in the Spring and Fall we are treated to very heavy wind storms. We often see sustained winds of over 50 mph during the day that go on for many days, and an over-shelter like the one in the video would have to be very strong to withstand the winds here. We do use woven plastic mats stretched between poles like heavy dining flys over outdoor structures like playground sets and carports, but they only last a few years before they need to be replaced. Also, passive solar cooling stopped being a thing here when everyone got electricity. I'm not saying that passive solar cooling wouldn't be a good thing down here, just that it was cheaper to use existing building designs and hardware common in the rest of the U.S. than it was to design unique buildings for this region. Don't forget that price is always an important factor in building construction. It was cheaper to do what was already the standard in other parts of the country, and just run the evaporative cooler during the day to keep things cool. P.S. In the past we made buildings here with thick walls made from adobe, and they were very good at maintaining a liveable temperature inside them, but they also required a lot of upkeep, and the nature of the material limited what you could do with it.

I once thought of a design here in the US for a mobile home park. Set up a solar panel system on top of the mobile homes that cover the entire roof, and have it raised to allow air flow between the roof and the panels. It would achieve three things. First it would be an entire electric power plant. Second help cool down the trailers. Third protect the roof of the trailers from rain which could over time leak into the trailer. What I didn't think of was an airplane foil.

A friend of mind in Washington State has a triple-wide manufactured home. He added a “pole barn” roof 4 feet over his house. It not only provided shade in summer, which sometimes topped 105 degrees, but helped in winter as well with the “snow load”. He did extend the chimney from his fireplace up and through the added roof height to keep smoke from being trapped inter the added roof even though the “pole barn” was open aired on the sides, smoke could still be caught under it on no or low wind days. This was back in 1988……Cheers

Give us the statistics: Temperature in the sun, In the shade, and with the Venturi roof. Is it an open roof gap over a ceiling built as an inner roof? Are there vents in the ceiling? One side elevation shows a flat inner roof and curved outer roof, another shows a curved inner roof and curved outer roof. Which is it? Ventilated roofs over ceilings are common in hot countries. In Thailand the gable angle is very steep, about 50°, to allow the hot air to rise. Fans are used to create a breeze. In Thailand often a flat roof becomes an open air top floor over which a gable roof is built for extra shade, This floor is commonly used for clothes drying, which in itself reduces heat required to evaporate water. Bird wire is needed to stop flocks of birds nesting and pooping. The houses are often raised one floor height above a pond of water, or in modern times, above a car port, bathroom, laundry and open kitchen, Traditional houses did not have glass or fly wire, this allows full natural airflow. Mosquitoes and insects can be a problem and insect nets over beds are often required. Verandahs prevent the sun from shining on the walls, and usually have herbs and plants growing in them to the increase shade. Sometimes verandahs are so wide that there are no inner walls. I have 37°C in the carport at 4am in the morning. Thermal bricks hold the heat making the house hot at night. This choice is related to whether the temperature drops significantly at night. Concrete block houses do not cool at night in Thailand, and need airconditioning. The break through is the Venturi effect of the roof. I need to see statistical evidence of the increase in air flow. I am sure it would be an improvement.

I believe,double roof with air flow in between, and maybe a sod topping and grass with automatic night watering if water is freely available. Heavy black plastic used for water sealing concrete slabs and walls, or over a timber, timber and iron or reinforced concrete slab all with plastic waterproofing, Consider reinforced concrete pillars and cement block walls with steel rods and infilled with cement for wall strength. Then mound earth up to the inner ceiling roof at an angle of 30° from the ground, grassed, the walls plastic waterproofed. Door and widows double glazed gas filled. I cannot do the engineering safety calculations. Imported steel and concrete are very expensive compared to local timber. Different tooling and jigs or boxing adds expense. 12' X 12' or 3.6m X 3.6m is the concrete slab module and 4' X 4' or 1.2m X1.2m is the strong timber floor stump spacing module. Wall timbers are at 2' or 600mm centres spacing. So 12' X 12' module are cheapest to build. Consider 12' X 18' living plus 6' X12' wet room Shower, basin, toilet, washing machine or trough. The kitchen sink and cooking area along the 12" inner wall on the opposite side to the wet room. All plumbing close. In simple timber cottages for a couple, the wet room was separate to the house for odour exclusion. We used to go to the toilet outside, and eat inside. Now we cook and eat outside and go to the toilet inside. The Asian wet area and eating open air downstairs and sleeping upstairs with the cooler evening breeze works but it requires an expensive staircase, and dust and no security from people.

95F is a cool day in western Texas to Phoenix AZ. In the southwestern area of the US temperatures can exceed 120°F / 48.9°C, Architect Frank Lloyd Wright designed a few buildings located near Phoenix to be cool in those high temperatures. Also homes in the American in southwest once used construction principles that allowed air to flow which kept them cooler. The Arabian area also built structures that stayed cool during extreme temperatures.

Yeah….I laughed at that. I live in the High Desert now, but used to live in Palm Springs. I would run at night and it was still 120 at midnight. 😂

A good number of years ago I did some thermal analysis with SolidWorks Flow Simulation, a tool used for analyzing products like computers and phones, to do some basic probing on the idea of a shade over a roof. What I found was that there needed to be a pretty good size gap, similar to the one shown in this video, to make the concept effective. It is typical of passive flow, density driven flows need a ton of space because the driving force is low. If wind were the primary driver, you could reduce the gap, but then the strategy falls down on a calm sunny day. The holy grail is a passive geothermal heat pipe that uses water as the working fluid. Heating from above, cooling from below is stable though, and can't be used to drive circulation, the driver being changes in density. Ever wonder why the stuff at the top of a cooler can be warmer that the stuff at the bottom? Heating from above, cooling from below, flow shuts down, and with the thermal conductivity of air being so small, the column stratifies thermally. Fun fact, the thermal conductivity of the materials that thermal insulation are made from is actually pretty high compared to the insulation as furnished. The reason is simple, insulation has one job, keep air from moving. The drag induced by insulation nearly eliminates the effects of density driven flow. The Achilles heel, wind loading on the shade is high in storm conditions, so designing it to withstand high winds is probably cost prohibitive. Probably better off designing to be easy to repair than resist crazy wind that only comes around once every 10 years.

Thia is exactly the ideas that need to be inforporated everywhere around the world since the flimate is heating. Im from eastern europe and 20 years ago when i was kid i rememebr summers being much midler than now. In most apartments people now must have ac's or they cant live comfortably. New building are so badly planned,no roof overhang, huge floor to ceiling windows facing south. No large trees around the house. Absolutely crazy that elthey think ac is going to solve all that. Well good luck

Roughly 20 years ago, Dwell featured a home in the Southern California desert near Joshua Tree called the “Desert Shed.” It featured 3 main features: 1. A concrete slab that was at least double the amount of a normal 1500sq ft home with the house built directly on top of it (to reduce temperature swings from such a massive slab), 2. A metal roof built up over the house for the previously mentioned venturi effect, and 3. The house was south on the slab with its windows facing south to gain solar energy in the winter and take advantage of full shade in the summer.

Saw a few years ago a television programme by the British adventurer / outdoors man Ray Mears. He was in North Africa around the Sahara Desert. He had a Land Rover parked up. He said that he would normally use two parachute fabric covers spaced approximately 30cm apart. He said this kept the temperature down a considerable amout in comparison to a single layer.

Such an elegant solution! The architect was excellent, and so was the explanation. One other thing about air conditioning, it dumps the heat taken out of the inside of the building to the outside, making areas around the buildings with a/c even hotter. Also given human nature where when a/c is available they often crank it up so it is freezing inside, instead of just comfortable, wasting energy. This was a great video, would have liked to know the temps inside the building when outside is 40 deg.C. How much it can cool?

This is amazing and inspiring! Great strategy for living in hot and extreme climates. Another good strategy is dome roofs. And my favorite strategy of all is building (and growing food) underground, like with earthships, hobbit holes, and the Forestiere Underground Gardens, in Fresno, California. The Underground Gardens are an excellent example and definitely worth checking out! Thank you for this video!

This system works best in arid climes where the humidity is low. With high temperature/high humidity situations, natural cooling is much harder to achieve, though this might be as good as any.

The best part about passive designs is you can slap air conditioning on top of them and it'll barely run, but when it really does get that hot where your passive design allows the temperature to rise past 80F, you have the option of turning the AC on. Sure, without the insulation typical in the AC paradigm of an American home the AC will be less efficient, but with all of the passive energy savings you already have, that's okay.

Many old buildings in Europe, like churches or monasterys, are build with stone walls of like 3 or 4 feet thickness. They stay cool all over summer as when the stones are finally heated up, summer is over.

So pretty much what is common at least with the double shading having a roof over a roof or a canopy to take the most direct heat of the sun. But pretty ingenious design itself. I bet even common jars of water near the ceiling may be employed to reduce the heat by evaporated water

This principle of space between roof and building is already applied very widely in my country (Romania) and most of Europe, because of the harsh climate. Almost no building without it. The space is much smaller (1-5 cm) but very effective in winter too against winds. In winter, the air flows slowly, keeping the heat and acting as an insulation by itselph. In summer, air flows much faster, cooling the house. There are matrices/blankets made from 3D metal wire mesh, of 1-2 cm, that you put under the last layer of the roof, that let air pass through it.
