For lumberjacks everywhere ✊
Can you guys please make a video on the history of American infrastructure and construction. I’m thinking about the roughnecks that built the New York skyline and things like that. Watching this show called America in Color helped me realize how much I want a video like that. Besides that I love your guys work. Keep it up!
Most of the forestry in North America is first growth, and not managed in the quaint, specific and very idealistic European way.
In fact many of your citations come from the Province of British Columbia, which is where I live. Currently they are handing out many old growth logging permits and there is huge protest. These statistics are not reliable because they come from a source that actively promotes and profits from forestry - managed or not. I can assure you that I have been across great expanses of this province and much of it being logged is first growth - they call it managed because they intent to plant it after harvesting.
Please search Fairy Creek protests and you will learn about the darker side of forestry here, perhaps that will influence future videos you make that promote wood construction.
Words like "all" and "should" invite opposition and spite. Stop shoving your greenie bs down our throats.
@@srpacific I would disagree. I come from a part of the United States where 100% of the timber comes from renewable forests.
You're putting far too much reliance on the integrity of the logging industry.
I work in architecture and I'm a huge advocate for timber construction, but not EVERY building should be timber. Always design within the context of your project.
Timber skyscraper starts on fire
@@JK-jq7rc and believe it or not, is more fire resistant than steel. This is not a concern. Buildings are fire protected by law no matter their material.
@@nickmcgarvey6463 that blows my mind
@@JK-jq7rc Hold a lighter up to a timber and see what happens.
Also, steel loses its strength at 1000 F and the building will begin to collapse. Wood only loses strength because it shrinks from burning away.
@Fremen yup! I do know this
"Why wouldn't you? " Have you SEEN the PRICES of timber lately? It probably costs less to build a house out of 24k gold right now...
For retail the prices for timber would be more volatile sure. but if you are a construction firm buying in bulk and in advance (possibly the price could be fixed beforehand with contracts) the prices would likely be more manageable
unfortunately i dont have any source to back this claim. but with what limited knowledge i have in economics it probably holds up
Jonny Boy spot on lol
@@manngaiho1012 yes and no, short answer is no but long answer is yes for some. While the prices are high now the construction firms can deal with the prices but they will still pass that off on to consumers. So while the prices may not be too large in comparison to if you bought it yourself vs bulk, it only works for the largest of firms and the prices will still effect the overall situation.
@@manngaiho1012 Im in the land development industry and lumber prices across the board are insane, doesn’t matter if its wholesale or not. Pro formas are being revised showing multiple alternatives now for so many projects

"Why All Buildings Should Be Timber"
Wood Lice: "My time has come" 🍴
Do you mean termites and woodworm?
Woodlice (little armoured bugs that roll up) just eat rotting leaves and detritus. 😅
I wonder what would happen if they actually tried eating treated wood haha
I just called an exterminator for carpenter ants. They’re some bad mofos.
@@badatcad treated wood looses its defenses eventually
@@friedit7862 The wood like anything would be on a concrete foundation, have a floor layer above the wood itself, and the building would be wrapped in a building enveope that protects it from certain damaging exterior factors, or would be re-treated after a given time like we do with roofs.
As a builder I would say multi-storey building in timber is a real pain. The local Fire authority will not leave you alone and the amount of temporary fire protection you need to have in place is way over the top compared to traditional. Also I still have memory of that project in Hendon back in the noughties that burned down to such a high temperature that it was setting neighbouring properties on fire by radiation alone. Sorry but at least with the Grenfell tower the concrete superstructure was still intact and it was suggested that there was refuge in the communal core store rooms which was made up of concrete walls if people knew about it. I believe timber has it's place in low level building or to extend storeys to encompass a penthouse for example, but I would have preference for concrete for main core structure. Also for dwellings and hotels timber frame can have bad acoustic issues if you get it wrong on site. I'm actually open minded, but we need to be very careful here with regards to medium and high rise as another mass carnage tragedy is around the corner with regards to fire. Most likely accelerated by poor maintenance when messing around with the drylining and fire stopping as the years go by.
CLT and other structures need to be used with other materials which compensate for their weaknesses, its the same with concrete which needs steel to hold it when in tension because concrete is weak in tension, strong in compression. Engineered timbber has a lot of shear strength, and will likely need a material to combat its potential vulnerability to fire, and our fire resistant technology has come a long way since the 90's. I would assume that building codes would require CLT structures/walls/floors to have the same fire rating as their steel/concrete counterparts.
I think a lot of people believing wood to be an inherently vulnerable/weak material neglect the fact that almost all materials are this way without a specific kind of treatment. Like how I bet anyone could crumble concrete that was in the shape of a 2x4, or easily bend a steel stud. It is all about how someone uses a material which makes all the difference, it is simply that architects now are confident in their ability to use engineered timber in what was traditionally concrete and steel's role.
mh most points are false wood is amazing if u prep it the right way it cant even catch fire anymore but most people dont know those tricks
I agree. I'm not nearly as educated in building as you seem to be and my original thoughts were similar. All to often we have seen great buildings built with great engineering be reduced to rubble years down the road due to poor inspection and maintenance. Buildings change owners, lose their value and next thing you know you have owners cutting corners trying to salvage profit from a once highly valuable structure.
Yeah, most "we have fireproofing measures now" arguments neglect the actual data on fireproofing. Basically that it makes it less likely to catch on fire, but once it's on fire it's as bad or worse.
The issue of C02 can be mitigated by using steel furnaces and concrete plants that are powered by electricity from Nuclear plants rather than fossil fuels.
Issue with "sustainably" managed forests it's that it's often just masses of Spruce being planted replacing indigenous species of trees which create ecological deadzones.
That is certainly true, although not in all areas of the world. Take a look at countries like Finland, where the forestry industry is a huge business, but also is done in a massively sustainable way in regards to selective harvesting and the replanting of harvested areas.
Instead of complaining about the flaws of the solution, why don't you provide a better solution to the problem we have on hand?
@@Oroquieta Solution is obvious, plant a mixture of deciduous native broadleaves. Reason they wont it because of money
@@dylan2785 It's so cute how ignorant you are, do you know why they choose to plant certain trees for renewable woodcutting? It's because those trees can grow at a rate faster than other trees, so chances are your obvious deciduous native broadleaves WILL BE overshadowed by the woodcutting trees grown beside them.
And trees need sunlight, those "deciduous native broadleaves" will then be stunted, and when the time comes that the woodcutting trees are ready for harvest, those "deciduous native broadleaves" will not be at a size and maturity that warrants the woodcutters of the future to spend more time and money actively avoiding damage to them when cutting the woodcutting trees.
@@Oroquieta That's a lot of words to just agree with what I just said when I said "Reason they wont it because of money". Have a nice day
Do a video on bamboo construction as to why it is not widely used despite its strength and availablity.
I'm looking for this one too, but i guess it's just good for small scale infrastructures. Maybe hehe.
Id be interested
Is scaffolding collapse normal. Or is it just unregulated with bamboo?
North America and Europe have never used Bamboo for large developments because Bamboo is not found in these regions. Wood is a great material and many don't want to change that.
Bamboo has a bit of a problem with water.
I'd love to know more about timber's seismic tolerance, water resistance, and how termites may/may not contribute to longevity
Seismically speaking, timber usually results in a significantly lighter structure and as a result the forces which occur due to ground movements are also less. Timber is also stronger the shorter the load duration is. Unfortunately, it's major flaw is that doesn't yield--it ruptures, so to achieve decent ductility we often use special steel joints at certain locations on sensitive structures.
As for water resistance, it depends how wet, for how long and the layup. CLT is not too bad when it gets wet for short periods of time because the orthogonal layup helps resist movement. If your building is prone to getting wet more often you'll need to protect it or use another material.
Termites you deal with as you would with most timber buildings,: chemical treatments and ground separation.
Carpenter here. Not all wood is created equal. Some, termites will ignore and don't even need to be weather treated for ground contact - something that will rot most wood in no time at all due to moisture. Alaskan Yellow Cedar for instance, quite incredible stuff and smells amazing. Even if you can't find something as great as AYC in your region, you can just treat the wood with protective chemicals. If you can make concrete and steel skyscrapers earthquake proof in Japan, you can make wood the same. It's a matter of choosing the right wood for the job and laminating it with the grain in the right direction for the purpose - then it's up to the engineers to fit pieces together for the needs of the structure. Wood is incredibly variable in its tensile, bending, shearing strength, and hardness from species to species. You'll find something that works for the job.
Most of the timber used today is the cheapest and weakest available, that's why most houses would not be able to withstand a flood or tornado, extremely prone to fire and there's not much longevity to it. In the early 19 hundreds the wood they used was much higher quality but also more expensive. Today it's just about building cheap and fast, this video is probably sponsored or has ties to certain companies so it's biased and wrong. Maybe if you're in a place where there's no tropical storms or fires then you should be good.
isnt there a 600 year old castle in japan made from wood
@@yato329 True, but its a castle. No air conditioning, no running water, no central heating no electricity no nothing. Besides shuri castle burned. Foundations are stone anyway. Also not that big on furniture either....
I'm just imagining a skyscraper on fire and Aragorn screaming: The Beacons of [city]! The beacons are lit! [Company] calls for aid!
This is my personal favorite comment I’ve seen all month!
“Why ALL buildings should be timber”
Only a Sith deals in absolutes…
That would be very stupid to use timber for all buildings we would deplete our forests quicker than we can replant them you got a think they won’t become full size trees and just a handful of years they take thousands of years to get that big
I live in BC and they're still cutting down the last of the old growth forest here, forests need time to mature and build into functional ecosystems but here they treat them like farms, where the soil gets more and more depleted each time they clear cut
@@Paul-ng4jx How many trees do you know about? You have a highly distorted view. There are lots of trees that grow much more quickly than that and the video explains that they are using more than just normal timber. I guess if you actually watched the video you might have noticed that.
@@treyjowers The wood density and strength of fast-growing trees are generally terrible. So his point still stands. Fast and good never works... But of course, people are welcome to make bamboo houses if they want.
Not to mention that the brown dry rot, even with treated wood, causes insane losses every year (£200 million in UK alone)
@@filipkilibarda8952 yeah but when concrete fails the entire building has to be brought down as apposed to just repairing it. Look at what happened in Florida. Probably would have been avoided if it was easier to fix that it was to ignore it. There are definitely pluses and negatives to both materials Not saying your wrong at all. But its good people are trying to find some kind of middle ground to create the best outcome.
Hello everyone, thanks so much for watching Tomorrow's Build!!!

Imagine waking up one morning and seeing notifications from BOTH the B1M and Tomorrow's Build. What a time to be alive
@@TheMaxi5757 They have 3 videos out. It’s like I’m in heaven
Imagine not getting a heart because you comment too much 😂
greetings
Too funny! I'm old enough to remember when the flavour of the day was "we have to move away from using lumber so as to save the forests". Special interest groups are always so self assured in their "solutions".
next will be " why we have to move away from timber structures and start building everything out of plastic"
People will tell you anything, when they are selling.
well back then the forests were not replanted with the same speed. since it was used for building, and heat and furnitures and all kind of stuff, but they were not cutting with the same speed as replanting. yeah. it kind of make sense to stop to "save the forest"
but there is also that business part.
timber industry will show you the things it is better than concrete. the concrete industry will show you the thing concrete is better than timber. and so on.
Oohhhhh the SPOTTED OWL!.. WAAAHHHHH!
Been alive for more than a decade now special interest say the other way
Y'all know that most engineered wood is made with a whole bunch of petrochemicals, right?
So? Is that amount of petrochemicals significant in any way?
@@rhalfik of course not! But sequestering carbon through the use of the main ingredient wood might have some preferable impacts, even for the "nay-sayers" of the world?
@@canavar1435 It's all in the numbers. I prefer to leave that to scientists and go about my day managing my personal carbon emissions.
Wood is one of the possible solutions and now we live in a time period, when these solutions are being tried.
Pretty much everything in the room you are sitting in is made with petrochemicals. Chemistry would be a very boring specialization if oil didn't exist.
@@rhalfik I too, hold in my farts for the environment
This video has been proudly sponsored by the Termite Union of the World. Thank you for your continued support.
😂😂😂😂
They treat it with a environmentally safe fungicide/pesticide so that's not a worry.
Besides, humans have been building with wood for millennia.
you win 🤣🤣
@@briansmith8967 And there's always a good reason why we stopped, it was not economical and often resulted in immense fires that could swallow entire blocks if not entire cities as in the case of The Great Fire of Rome. Not to mention placed with intense rainfall/floods, high winds, or earthquakes would also be at extreme structural risk regardless of the exact methods used. Even the Romans understood this and gradually switched to using concrete for apartment buildings.
lol nice!
Watching the video though, I can't get past the fact that they're effectively talking about building with glue & using timber just as the glue base, so termites might not be too keen on a diet of glue
"Timber is better than steel"
doesn't talk about steel at all
the main issue with steel is corrosion. A recent example is the Florida hotel in which salt water had found its way in the cracks of the concrete and quickly deteriorated the steel bar reinforcements. Subsequently the foundation weakened enough for a failure.
Last time I checked, steel/concrete buildings aren't lasting as long as even your most basic cabin/colonial house; many of which are still around from hundreds of years ago. Steel/concrete deteriorates much quicker. wood needs less maintenance too.
@@87_North If thats your argument, might as well go back to building with Adobe Bricks. In comparison to wood, theres structures millennia older and less damaging to our trees....
@@87_North Because we design steel and concrete buildings to last around 50-100 years. It's intentional.
@@mrfinder18 Well....the proof is in the pudding. We have options! They're making prototype Mars bases out of corn and soil like that found on Mars. We gotta be creative with this shit
"It's not a question of why would you build it with timber, but why wouldn't you."
Great Chicago Fire: *laughs in death and destruction.
My exact thought as well! lol
did you not watch the video in which he spends a lot of time to explain the fire safety after appropriate manufacturing
@@cheinssvd27 not once did he address the fact that it’s FUCKING WOOD and it burns better than anything save for something like wool or hemp. He baited at the start then only danced around the issue when it had to be addressed “wood CAN burn more predictably/it CAN be made ‘safer’”. Literally as sketchy as it gets.
This entire video is just, "I know we have hundreds of years of collective experience across the world on how and why to build modern things the way we do, but my feelings tell me that we should only use wood because it is more environmentally friendly. I am much smarter than those thousands of engineers that contributed to structural design regulations."
@@tcp8946 basically
This is one of my favorite videos of yours! I love timber, the warmth it brings🌲💚
There is a building that is now fully constructed that was built out of lumber in Portland that I was invited to do a walk-through after a large wind and rain storm came through causing the building to bulge apart at the top.
Every floor required re-design to correct the severe safety issues, as well as to dry the wood before sealing it.
They used cables fastened to the floor to pull each side of the building into the center on every floor, and also needed to secure the rafters on each ceiling on every floor due to the wood drying and shrinking. Practically halted construction until they could figure things out, and wait for the wood to dry.
Can't recall which building it was, but it was in downtown Portland.
The B1M is one of the reasons why im studying civil engineering and i couldnt be more excited for this new channel! Awesome
Ah thank you so much!! Good luck with your studies, you have an amazing career ahead of you 👍
That's great, too bad they got this one horribly wrong. Western Europe's companies are "sustainably" sourcing timber from eastern Europe where it's cut illegally in massive quantities by local companies. More of the reports are coming out about this practice. This video is a slap in the face of all people who are actually aware of this and I am quite disappointed by the B1M for not doing their research beforehand. You can Google "eastern Europe secular forest illegal cutting" and see the top of the iceberg. I really hope that while you study civil engineering you will learn to look beyond greed and profits in what I'm sure will be a great and fulfilling career. Good luck!
@@katnonumb thanks that someone mentioned it. Allso no mentioning of recycled wood, there are a couple of plank types made entirely of old wood. This is necessary as we never could build everything out of fresh wood. And didn't even mentioned the fact that wood is currently used as bio fuel wich is like the stupidest thing ever
@plsbqwhy8t nthabak So what you are saying is that it's ok to blame it to local greed and let's continue cutting down their forests illegally as long as it suits our needs. Try interviewing for IKEA, they will hire you on the spot.
I'm working on a Bachelor's in Wood Engineering in Ukraine, and this video was really motivating.
How are you now?
I think it is better to build some buildings with bricks/stone instead of wood. Because wood doesn't last forever while bricks/stone can. But if the building is not designed to sast forever, it should be build with wood.
As someone who worked in Kobe Japan soon after the Dai Hanshin Shinsai, I can say that the #1 reason people died from the Kobe earthquake was not from building collapse, but being trapped under fallen wooden structures that caught fire.
Apologies, but I disagree. Not all buildings should be made of timber. There are many other factors in which to consider.
Except they used techniques that can absorb the shock of an earthquake. It's not the same as a normal house made of timber that is also not treated with fire suppressing material. Watch the video again.
👍✌️
@@asdf3568 considering japan, they probably already used the techniques ahead of the world... and japan earthquake is fkin frequent and big
I would like to see data in the rates of smoke and heat; and how fast they would increase compared to concrete/bricks. Sure, it wont collapse. Yet in the mean time my burning ass will still be inside a literal campfire.
Kath Khuni houses are built in the Himalayas that withstand many earthquakes there & they are natural builds of stone, timber & gravel.
TB: “the old problems of strength, fire and deforestation are all being answered. The old excuses for not using it has fallen apart”
Brazil/Congo/Indonesia: old my beer!! 🍻
On a serious note, you can talk about this in some developed countries, but most countries in the world are far from being sustainable in forestry.
They will have to catch upp.
As far as I know, the forests mostly cut for agricultural use not for the wood itself
@@user-zh6ec7fk1w There are some issues around the harvesting of certain exotic timbers like teak, mahogany, and rosewood but by and large the largest contributor is indeed land clearing for agriculture.
@Mobus Seven I know.
But to save the planet everyone will have to work hard.
Old grouth rainforests in Canada are being logged and distroyed for lumber not everyone is using sustainable deforestation.
We got it right from the start. Stone. We should just keep building with cement. Degradation is by the eons with concrete, specially when taken care of.
The issue is sourcing; for stone, there are only so many quarries and for concrete, there's only so much concrete-quality sand available. Humans can grow trees in a reasonable time period but it takes eons to produce sand or stone.
@@deliciouslybrutal Not really. If you think trees youre probably thinking pines and such. Heck even wallnuts. But trees....eh...there is no reliability with trees. You might get a fuckton of lumber, you might get jack shit twigs . Shit, I think probably entire structures made from polymers and alloys are more viable than both..... as a woodworker wood is good for small things. But not city grade construction work.
@@cactusmann5542 you raise a valid point regarding material inconsistencies. While the video did make a point to say that they're talking about engineered timber (rather than raw lumber), i think you point about inconsistent yield still stands.
That being said, while polymers and alloys are great materials, right now, they lack in the sustainability department. The world probably can't sustain having every structure be an ultra durable alloy or polymer.
To me, I think the point the video is trying to make is that engineered wood allows for 20th century architecture and building techniques, while using a much more regenerative material so we can still use it in the 2200s and beyond.
@@deliciouslybrutal Irregardless of what they say, eingeered wood is not even proper wood though. With fiberboard, laminate, chipboard you get none of the benefits regular wood gets. No rings , nothing. No matter how much we try, one made in nature would still be better...And there is of course the plastic and the chemicals...
So ultimately inferior to both polymer and regular wood.
Exactly what the fuck I’m not falling for this after reading the three little pigs story. Unless your house is made of stone a werewolf comes and wrecks it. Nice try, asshole.

There's a reason old buildings like castles, churches and pyramids still stand. They were built with stone and similar material. I now live in the UK, where most houses are built using wood, and they're terrible. I've met many people having issues with their houses falling apart because of humidity and stuff. I never heard anything similar when I was living in Spain, where houses are built with proper materials.
Bc people don't do maintenance in their houses , nothin to do with the material
@@COREDYNAMICSLTDA Answered to a comment while completely ignoring the main point of it... I'll make it easier; it doesn't matter how long you leave a stone out, it will never rot or have termites (or other insects) destroy its integrity. Maintenance isn't part of my point, wood will always decay faster than stone or cement.
Of course, they do because they have been preserved. In 1000 years no one is going to be trying to preserve a 2023 townhouse.. The current way people build houses with timber, especially in places like the UK where housing is about profit is cheaply and poorly done. This video is discussing how the technology is improving and what can be done. You're talking about timber-framed houses, even though its made out of wood you should consider it a completely different material from CLT.
Please do a complete energy analysis on this. In other words the energy costs of growing harvesting processing treating the wood versus energy cost of smelting iron. And have this analysis done by a neutral party. I’m really curious what the results would be because sometimes the “Obvious” greener path isn’t always that case.
Take into consideration recycling of those materials.
Just follow the $$.
In Material Science (also part of engineering), there is always a justification for the use of certain materials. I still think metal and concrete are better building materials due to their long term rigidity, low moisture permianbility, low thermal and chemical reactivity and so on.
I'm more interested in the impacts of the glues that are forming such an integral part of these new, futuristic "timbers". I don't see any mention of the environmental impacts of them!
Done *right* , using more wood and less concrete and steel has the potential to reduce Co2 production of construction a lot. But there are many, many factors to consider. There is certainly no one right answer for all buildings in all places. Any comprehensive analysis has to take into account whether materials are being shipped long distances, whether the wood is truly sustainably harvested, where the steel comes from, etc. The analysis must take into account the location of the project. Thus, the same 2 test buildings, one wood, the other concrete, built in Stockholm, Sweden, or built in Riyadh, Saudi Arabia, will have 2 very different results, just because of materials having to be shipped different distances.
It's crazy to think that we can grow trees fast enough for this. Unbelievable.
Its actually dumb. A tree takes years to grow
@@Goch46 While true, the same could be said for the aging of wine. You just need to calculate the demand you will have in the future and plant accordingly.
@@hectorcastro8374 a quick internet search (maybe wrong)writes that the tree to get cut needs to grow for around 40 years to 150. The demand is for sure going to increase if this material is great, but growing the trees will take as much time as it needs without caring about the demand.Tbh I find it really hard to plan at least 40y ahead. Trees need their space too and is going to be harder and harder to plant panned forest to get the timber without taking the space of something else which can also be important. While I love the idea, I think it is too optimistic to be true.
@@sergioospina2986my family owns a forest and I work in it every year. Once 🌲 is 30 years old, it becomes targeted for different bugs that destroys it. So idea is not that crazy of you want healthy forest.
There's already a major shortage of normally sourced wood, much less freaking "sustainably grown" timber. Whoever wrote this probably needs to get out of their bubble and see the real world because it's shockingly out of touch with reality.
I worry about damp. Not what's already in the wood - you've covered that, but with high humidity or constant rainfall.
Wood lasts for centuries when water penetration is controlled. Mineral wool has proven to adequately protect wood from water damage.
@@timothykeith1367 dude, what are you talking about?
Wait, are you saying those companies are building millions to billions dollar building with the world leading professional without solving these problems?
@@christianyobel117 No, but I'm curious as to the climates this is suitable for, and those it is not. Also it's long term durability. Some buildings are only built for a 20 year lifespan, others to last a lot longer. I just want more information.
@@ravenfeeder1892 well actually I'm quite curious as well, but with our technology hitting the 100 year durability should not be a problem in my opinion, i just found out there's a ton of wooden building dating close to a millennia and still standing. Even at my local area there's one more than a century with zero technology. So yeah, i feel optimistic about it
Living in an area that’s got heaps of termites and seen first hand on homes what termite damage can do I would never build a house of of anything else other than bricks.
i like brick houses but behind & under the bricks are... wood.
@@gameguy5764 double brick FTW
well then maybe you live in an area where wood wouldn't be the best solution after all. Nevertheless, I too think, that wood construction is the future in most parts of the earth!
yep. trees help you breath . in 21st century you can buld houses from many other materials
@Sweet Rebel steel?
Fascinating!
Recommended your video to my Building Code class. Thank you for posting this!
Wood prices are up like 400% right now in the US lol
The cure for high prices is high prices
@@nathanglessing9010 Hehe. True.
This video somewhat misrepresents the nature of the hazard with regard to fire. Although it is mentioned that wood materials can char as a way to protect the structure and that gypsum board is often used to encapsulate wood structures, it is the building contents that often pose the greatest fire hazard. For this reason, it is important to also emphasize the importance of active fire protection systems such as automatic fire sprinkler and alarm systems in conjunction with improved structural systems.
Thank you for this! I have always loved constructing with timber, over 35 years as a framing carpenter I have witnessed the birth of many amazing materials. LVL beams, I-joists, OSB sheeting, and other engineered materials make framing better, stronger, and faster than ever before. When I hear people say "they don't build 'em like they used to" I laugh and shake my head. 😂
You should see all the fuel we burn to make the fireproofing resins for this stuff. It is some dirty ass chemistry as well.
This stuff is religiously insane...get out while you can. I have truly come to believe if an actual "climate catastrophe" of any sort occurs, its crap like this that is going to be what causes it.
All you need to know is the cost of something (including subsidies) = the fuel burned to make it happen.
.....If you keep that in mind, and are honest with yourself, this should be making you sick.
Excellent video. Very very interesting. I am still not sold on fire resistance though. I think I still would rather be in a “fireproof” concrete and steel building, especially if it is a low-rise or high-rise building.
Hang on!
Isn’t EVERY building “a low-rise or a high-rise building”?
This video gives me good vibes about my new house in the mountains, made with lots of timber beams throughout. And I've been saying for years that trees are a crop and this really confirms that.
People are a crop. I’ve been saying that for years. Seeing the world as a resource instead of a relationship is the heart of ecological destruction thus human destruction.
@@davidcanatella4279
cannot agree more. Leave the trees alone.
Absolutely beautiful
I'm a structural engineer. I once had a client ask me to assure the home I was engineering for her had no wood in it. She didn't want to do damage to the earth. I wish I had the confidence all those years ago to show her images of open pit mining and blast furnaces to produce her steel and cement!
just plant more trees .
One thing I never got with sustainable forests is that, if they planting new trees, won’t it take years for that tree to grow to be used? Isn’t there only so much old trees to use? Some of these projects seems they require a huge amount of timber. If everyone used timber wouldn’t that deplete usable trees too quickly before new ones are able to grow to usable age?
Well, you "just" need forests that are big enough to negate that issue. Europe, and northern Europe especially, has miles and miles of forest.
In the end it's just about keeping the forests sustainable, unlike they act with the rainforests.
Yes it will take years for that tree to regrow. Which is why they probably won't see that section again for a couple of decades. And that's why the goal is to plant more trees than they took out, to account for that increased demand in the future. Rotating around isn't that hard when you've got thousands of acres to work on.
A huge benefit with harvesting old trees for construction, is that old trees doesn't really grow all that much in a year. This means that the rate it stores carbon slows down. Young trees grow faster and therefore store carbon quicker. Thus, removing old trees to make room for new ones, and then utilize those old trees in buildings that can stand for maybe 50 years or longer, can be more sustainable than letting the trees die and rot. Remember that the carbon will be stored in the timber until it degrades or burns, esentially working as "carbon magazines".
Oregon has been sustainably managing our forests for more than half a century now. A Douglas Fir grows 3 feet per year from age 5 to 100, with maximum growth coming after 20 to 30 years. Basically we’re already harvesting planted trees. There’s more than enough forest land to maintain and increase lumber output in a sustainable way.
That’s not to mention selected harvesting, fire control clear cuts, breaks, and thinning. Sustainable timber is absolutely possible, but it would take some shifts in other wood uses, and would definitely need to be buttressed by advancements in other materials too
If you’re thinking this from a carbon sequestration point of view, old trees don’t really store much carbon, newly planted growing trees do. Though tbf trees don’t remove that much carbon anyways, other things like peat does
Haha, New Zealand insists on building with timber for some strange reason and nearly every wooden structure 20+ years looks dilapidated and in need of demolishing.
This was an awesome video.
Great video! You should touch more on how sustainable forests actually work though. I don’t understand how we’d be able to plant enough and grow them quick enough to keep forests in tact seeing as mature trees are 50+ years old
Due to the increase CO2 in the atmosphere trees grow from 20% to 50% fsater than 50 years ago, but the sustainable forest is a myth, at least in europe. The western europeans like to brag about their sustainable forests but then go to eastern europe and bribe politicians to steal wood from our forests, then when the people at the forest guard start signaling it they get fired or killed in some instances.
where is all the timber going to come from?
maybe it will come from the logging companys back yards/cabins?

I love what architects can design with timber! Such a warm and classic look while still being modern.
The sneak peek @5:34 of the Ascent Building in Milwaukee looks absolutely gorgeous and modern with its overabundance of windows. It's cool to see wood used in traditional, experimental, and modern looks.

"Why All Buildings Should Be Timber" 2021
Meanwhile Chicago in 1871..
️"🔥️🔥️🔥️🔥️🔥️🔥️🔥️🔥️🔥️🔥️🔥️🔥️🔥"
I was sceptical initially, but you have used pretty convincing arguments. Well done 👏 looking forward to timber buildings future
Generally liked the idea but worried me when you mentioned charred wood burns at the rate of
1 mm/min giving you enough time to escape.
In comparison to concrete structures they can generally withstand fire for up to 4 hrs I think wood frames take less than an hour to fall
I wouldn't want to escape and then sit down helplessly to watch it burn away any way
Exactly, if you replace flammable materials inside a concrete house with materials that are as well treated for fire retardation as they claim their timber is then not only would the concrete wouldn't fail to the point the structure is weakened and unsafe, but it probably wouldn't even spall as the fire will never become strong enough to damage it.
The only thing I took away from this is that instead of having complicated internal walls made of wooden structure with insulation and then plaster on the outside it'd be possible to use whole wood panels with insulators in between.
But there's a reason no one does this, IT'S REALLY FUCKING EXPENSIVE. Can you just imagine how expensive a SINGLE outer wall made of solid timber cost even in 2018 timber prices? You might as well just build a 2nd house.
Traditional Japanese houses have a layer of charred wood on the outside to resist fire & insects.
And here in the US, most houses are timber framed houses that can last forever - if a tornado doesn't hit them - which is a more common occurrence than being burned down by fire.
If there's a fire raging in your house, it's because of an explosive accident or you are a moron who put other flammable materials next to your wood burning stove. Even extremely flammable Christmas trees take a lot of bad circumstances to kick off & most of those fires are insurance scams.
In all reality building codes would mandate that certain wall assemblies or floor assemblies have a certain fire rating. Your concern is valid but if the wall/wood were not to meet a fire rating it would be supplemented with other materials in the assembly to bring that wood up to the necessary fire rating. Certain woods like Shou Sugi Ban are even more fire resistant after a char coating.
Again, my point is that replacing the flammable stuff inside the house is a mich better option than replacing the house itself with materials capable of surviving the inferno of a wooden couch with polyvinyl based foam, which is scarily close in structure and properties to solid rocket fuel.
@@ScarletFlames1 You made very strong points, well said.
not to mention the life span of timber frames is almost half of reinforced concrete structures.
If this ever was the cause... Prices for timber would be nearly impossible to by as a normal civilian
That's the point. It's all about lowering the population and making things your family depends on more expensive. This is the core of every Green idea. Increasing prices in order to reduce your ability to support a family.
This argument doesn't make sense. Are bricks, cement and sand too expensive for domestic buyers to afford currently? No. So why would that be the case for timber
My parents were in the wooden Tacoma Dome when it lit on fire in the late 80's. Auditorium large enough for monster truck rallys and Bieber has existed for decades.
Fire: So you’ve chosen death.
So how about the cost? Probably the most important factor and also how long it takes to construct as it also plays into the overall cost? If its not cost effective it will be the the single and greatest downfall. Another thing to consider is how the building ages with all the stress, wear, and weathering especially in a high rise\sky scraper.
until 2021, a timber house costs about the same as a brick and mortar house
given the supply issues of timber during 2020 & 2021, I expect that the price of timber will go down significantly in the third quarter of 2021 and beyond
I found this particularily enjoyable as i am currently writing my MSc thesis in Mass Timber trying to aid the development through innovative designs.
Keep up the good content
Hard to imagine this in the states , where timber is meant to stand and grow till fire takes it away . We seem to think that
buying lumber from Canada is smarter than using the resources that are held hostage in the federal and state forests .
Fantastic.
Great video with the usual production quality. Subscribed!
Ah thank you so much!! Welcome on board!
Wood still rots, is prone to termites, mold, and in an age where weather is becoming increasingly risky, it doesn't seem like a good idea at all. Sure you can treat wood to be fire and weather resistant but no treatment is going to last as long as an innately solid brick or concrete structure. Forest fires becoming more common also means we could see sudden and long lasting supply issues. 3D printing also promises to further reduce the cost of concrete constitution and make wood much less attractive.
Yeah, reinforced concrete is the way to go in the US for many of our worst disasters - hurricanes & tornados.
I thought about wood rotting too. This only works on paper and the short term. A building wouldn't be built in a day so the wood would likely be rained on with no protection.
@@RGTube “works on paper in the short term” I see what you did there
@@hks-lion cool because I didn't
Concrete cancer is also a thing. Look at that condo collapse in Florida a couple of months ago. Nothing is permanent. Concrete is porous and mold can grow on it too. I have pressure washed concrete to remove mold.
In Milwaukee they are constructing the world's tallest mass timber structure, called Ascent. It's going to be beautiful when finished, and I'm also interested to hear how it ages through the years
Sadly they priced the units way above market and it sits half empty. Nice thought, but ultra luxury isn't appropriate for the Milwaukee market.

Isn’t building every building out of mass timber, unsustainable itself? Lmao
They’ve got managed forests, fireproofing, and increased strength. Which part are you referring to as unsustainable?
@@triforcelink Its still wood though. No matter how much you fireproof it, its still wood(and probably long term more cost effective)

Spectacular as always 🫶🌎💫
Grateful to you
I think a cost breakdown video would be helpful too. At least showing what the cost and benefits of current buildings would've been if they had been made of timer
8:38 Well, actually, the fact wood is seasoned to low water content level has nothing to do with its resistance to fungae, rotting, as the problem pertains to the inherent property of wood that makes it pick up moisture in the long term.
Right? Long term .. what if the perimids were made with wood. Or what if the great Wall of China was made of wood. Or what if the CN tower was made of wood. We all know they simply wouldn't be there now if they wereafe of wood. What happened to building for long term ?
@@msankoff maybe the buildings we have now shouldn't last a thousand years... At least when wood breaks down it doesn't need to be reforged to be reused.
I can bet that their next argument will be how rebuilding everything more often "creates more jobs" and that is "positive for everyone"
;)
@@msankoff I think you have, and many others to come will, misread my comment. I only pointed out the fallacy in the video. There ARE ways to make wood highly resistant to fungae.
Timber is good for non residential buildings since noise is usually not a concern. Nothing beats steel and concrete for less sound transfer between units.
In the U.S. most partitions in heavy timber buildings (Type IV) including fire rated one’s between units or corridors use assemblies of light weight steel studs and gypsum wallboard, or dry wall. Some CLT walls are starting to be used for shear walls as engineering knowledge increases.
this is so inspiring. i want tot live in a timber city !!
Nice video. Just wonder about the other factors like ease of transportation and constructability on site?

@@akbarzib4117 youre right on point
The pinblocks in pianos are constructed with many cross laminated layers of rock maple that endures 15-20 tons of pressure from the strings for 50+ years. Its a remarkable material.
But that is not the Material that they are talking of using here. They're talking raw and not refined wood.
The newest buildings in my city are mostly build out of timber (mainly the foundation) the only reason we could is as we have no droughts and forest fires in our country. Sadly the expected life of the foundations is 25 years so while we could build those multiple flats within 1 year within 25 years we have to build new ones. Concrete and steel foundations have the benefit of being used again and again for over 100 years making the construction more renewable.
These are just beautiful short documentaries, and they're for free. Thank you so much!
Our pleasure!
Well.. some of them are just sponsored propaganda, like this one
If this building method becomes widespread, this will probably causes lumber prices to skyrocket even higher with the immense quantity of wood needed to make large buildings
It's called a sawmill not a factory.
@@motionsick What's your point? Forests, sawmills, and factories (for turning raw lumber into manufactured building materials) are all involved here. It's possible for one or more of these to become a bottleneck if they don't keep pace with demand.
Too much consolidation of the saw mills they have no competition. The bigger ones bought up the smaller guys and shut down the mill. Same thing happened with chip manufacturers. If oil kept up most of the inflation goods in most of economy it should be close to 8 dollars a gallon today.
@@MatthewStinar same with pretty much every other industry, but those bottlenecks would even out incase of increased demand.
@@Leksuttaja149 "Same with pretty much every industry." Agreed, which is why I wasn't clear what point they were trying to make. 🤷♂️
As someone who literally does research on this topic. i can say that timber is not a replacement for concrete.
if you make a proper LCA analysis you'll see that there pretty much is no difference in using timber compared to concrete.
there are multiple factors for this:
1. amount used (wood isn't as sturdy, so you need more.)
2. wood might store carbon, but it also releases it at the end of its lifecycle
3. transport, (most countries don't have climates suitable for large scale production, and wood is harder to transport properly.)
anyway, i recommend using coulomb/beams structures for a more sustainable future.
Amazing
