My cabin of 30 yrs is made of concrete block and metal roof. Deck supports are iron poles. 9000 ft high in forest. I will be moving up there FT soon. In 2 yrs or less want to enlarge it. Had already decided on sandwich panel concrete walls and 2nd floor to be redone as concrete. Question - must a concrete roof be flat? I thought of SIPS roof with metal. But if concrete roof can be pitched as a shed roof, then that sounds good. We had a bad winter up there few yrs back where most cabins pipes froze, some roofs collapsed from snow weight. Not my concrete block cabin. We notice too that after 2 days of woodstove use cabin stays warmer than neighbors with wood cabins. I really prefer concrete. Always have (though my desert home is adobe brick.) In forest area, concrete is mice, termite and fire proof.
to people from other parts of the world. timber just recently became expensive enough not to be the defacto material of choice. the US has millions of acres of high quality timber. its different here.
The Asian guy talking at the end. i was abit confused what kind of concrete he is talking about? Housing in scandinavia? are like made 90% out of our pine wood xD with and exceptrion to denmark, but all the, but more people are starting to use precast stuff for saving time on the construction site.
This is awesome, would be cooler to purchase one & ship it oversees. We have land there, but no house yet & this is exactly what I'm looking for due to the fact we have cyclones smh.
If the material has high thermal mass, it would mean that it can absorb a lot of solar heat and would also take a long time to cool. Sounds like it would increase the effect of UHI.
Considerably more expensive to construct than alternatives (which is one of the chief reasons why they're not popular in the US) and the Tornado cannon is a publicity stunt. 10 inches of steel backed concrete vs what is most likely a poorly constructed brick facade.
Where i live we mostly build houses with iron pole frames and concrete blocks. Nobody would build house with wood framing. Even though my country is quite safe regarding tornados, earthquakes, etc... People still like to feel safe i think. What is the benefit of wooden house? Apart from being easier to take apart.
Concrete houses work better in some places than others. They are certainly a lot easier to fireproof. Thermal mass is a benefit if the temperature cycles around a comfortable mid point, but it can be a nightmare if it's consistently hot or cold, especially if you want to heat of cool rooms only when they are used. The only insulation in most concrete is that which is deliberately added, making the wall thicker and eating up space. Concrete can only be made earthquake resistant by adding a lot of reinforcement, and even then, any damage is harder to fix than with wood. Some areas don't have access to high quality concrete, and in some places, contaminated mining has led to concrete cancer of various forms (Google "cornish prefab", "concrete pyrite" ). Any structural problems in concrete are much more dangerous than those one finds in wood construction; almost all of the fatal building collapses in the world are in concrete and masonry structures. In cold areas, road salt can drastically shorten the life of concrete; my town had to demolish a parking garage that was only 30 years old. It's much easier to insulate wood frame construction without adding cost or bulk, though it's always better to add an external layer to avoid any direct thermal bridging. Contrary to one of the commentators in the video, wood construction can last indefinitely and is very easy to repair while modern concrete has about a 100 year lifespan in good conditions (it can be fixed with various patching methods, but it's an uphill battle). The special concrete they mentioned might have been some mix of Roman pozzolan concrete, which has lasted for hundreds of years in Italy, but it's not available everywhere and shipping can be a major expense with such a heavy material. The "tornado test" was impressive, but a big problem with panelized concrete, both precast and tilt-up, has been the joints between the panels (Google "ronan point disaster"; the temptation has been to bolt the sections together at the top and bottom, but they need a lot of bolts, or a grout-lock, to give the whole structure the strength of each panel (this is also a potential problem with panelized wood construction). Still, this system looks promising, at least for some places; I hope a marketable version becomes available if it can be made at a reasonable price.
@@pcno2832 You make many interesting points. What do you think limits concrete life to 100 years? It would be interesting to know how to increase the life span. Any thoughts on structures such as Coit Tower and the foundations for the Golden Gate Bridge in San Francisco? Those are about 90 years old. Curious about your comment, I looked around and found the William E. Ward house in Rye Brook, NY and the Highland Cottage also in NY from about 1870. Not sure how the concrete is holding up in those structures. Joseph Aspdin is credited for patenting Portland cement in 1824. I wonder if there are any structures from Joseph Aspdin still surviving. Also, curious about the pozzolan concrete you mention. I wonder what steps to take to make concrete last longer.
Thermal mass is not universally applicable. It works in climates where there is a high diurnal temperature difference. In my subtropical climate thermal mass is the last thing that you would want in a house. Light timber construction which cools quickly at night is vital to comfort. It is frustrating and disappointing to continually see prescriptive design solutions on the internet presented as the right or only way, when they only make sense in limited climates.
The video is incoherent -- it is supposed to be a net-zero passive solar house, and it's completely focused on concrete, which is nothing new. Those engineering and computer science students aren't working on how to put concrete panels together! LOL. Most of this should have focused on heating and cooling the house off the grid.
if someone wants to any new innovation create a house with off-grid ( electricity, heating, water, and toilet) then you can say its innovation otherwise making a concreate wall offsite and glow together or welt it is not an impressive innovation and also this should be offered able not in million-dollar, not everyone can offer million dollar.
The Universities and Institutions involved show how much out of touch of reality they are... Many countries use such designs for their homes already ... what a waste of time and money.
So, they are catching up to the rest of the world now and they are calling it “innovation and future”? 🤦🏻♂️🤷🏻♂️😂but I think they will lear the hard way not to combine iron with concrete that way to support the roof.
This is almost ancient home building technology. Africa does not make wood houses professionally. certainly poor people will make a house out of anything. But when a person builds a new house professionally in Africa, Its almost always all concrete. Many other 3rd world countries build concrete houses. The U.S builds houses that are wood and brick seldom block. They are now using concrete forms as if it were new. The reason the U'S builds wood houses is more political than economic. That's another story.
how can i get more information on the concrete..?
is there more information on this project. is there a website specifically for this project?
US: Look! I have future house design
The rest of the world: Dude, you are so late to the game.
😂 yeah...
Can we put cladding on exterior wall (natural stone?)

In India, all homes are made of concrete. Except the people under the poverty line, who build homes with wood just like the USA.

Desert Rat Gardener , you may want to look into heat melt embedded into the concrete roof.
Ski resorts use them.
Buck ey thhank you
its not that they are building a stronger material to build the house but concrete has a high yield strength under compressive forces.
What was the name of the concrete they were using, and how is the cost compared to regular homes
regular homes are always from concrete
