- The design and structural craft of building with wood in America is finally changing - for the better. Innovations in the timber industry and the rise of cross-laminated timber (CLT)* are forcing Oregonians sitting on the richest sustainable resource, the Douglas Fir, to rethink how to harvest, sustain and reshape the future.
*Cross-laminated timber is a wood panel typically consisting of three, five, or seven layers of dimension lumber oriented at right angles to one another and then glued to form structural panels with exceptional strength, dimensional stability, and rigidity.
With special thanks to the UNIVERSITY OF OREGON for presenting partnership, a world class stage design provided by HENRY V, an incredible legacy bound book provided by PREMIER and to the creative digital craft provided by ENJOY THE WEATHER.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

Kaiser recently concluded an 8-year term on the Portland Design Commission, which is tasked with overseeing the constant zoning, design and planning within the City of Roses. He is currently developing the tallest engineered timber building in the United States - Carbon 12.

Awesome. I'm currently researching CLT in the UK. This talk is brilliant. I really do hope Mass timber keeps growing in popularity.
This is wonderful
Impressive
An example of floor to ceiling used on my dads house in Auckland.
the japanese temple has a sort of pendulum in the middle of it that absorbs the energy of movement ...in the core of the structure 4 things!!
11:00 but how to repair the wall after the fire?
I think that i begin to see, a building lovely as a tree...
renewable renewable renewable renewable renewable
tree farm vs apex diverse forest ecosystem
i want to know how we went from trying to stop deforestation to wood being a sustainable material. how fast are these trees growing? i'd like to know more about what exactly makes it sustainable
Tree grows faster than we can cut it. thus sustainable
Wood is a renewable source of material. That's part of the criteria of Sustainability as a concept and discipline.
Pine about 20 yrs plus, and Oak about 30 yrs plus. Not truly sustainable
@@joeruiz12 Well you wouldnt use the slowest growing trees for this
Well, northern US could learn from a country like Finland about how to farm forests. It is like one of the main products in Finland. If you don't cut trees, they will only release the CO2 back to the air and soil when they die. But if you cut them, it is like storing CO2. A ton of wood is something like 10 tons of CO2 (because of binding C-12 to O2 and H2O). Also planting trees is a profitable thing to do. After 20 years, you can reclaim your investment. In Finland they plant something like 150 million trees per year (with 5.5 million habitats that is over 27 trees per person a year). And growth is still more than they can cut. The problem is what happens to wood product when it reaches the end of it's cycle...
convenient to ignore the pressure to monoculture the forests from your CLT.
ture, but that effect comparing to concrete tho? we have to do our weighing
You can plant different types of trees togheter, creating a better ecosystem
@@chrissie2732 Yeah but given the way our economic and governmental system works, that's never going to happen. Timber companies are going to use the most simple forestry practices to maximize the produced wood.
come to remote areas in Asian countries, Vietnam, China, Japan..., you can learn a lot about sustainable construction from older generation. Come as soon as possible before it's destroyed by younger generation and replaced with Western "modern" styled buildings
Don't they have modern wooden constructions? I thought wood is a big thing there even today? Besides, we can not compare how things used to be 100 years ago, many things were different, human labor used to be almost free. Then again I don't know about today's architecture in Asia.
What about wood eating insect
Benny Brinard Wood can be treated against termites
We went from building walls of logs to studs at 24” on center to now solid walls. And yet at 24” we were already running out of forest. Moreover, CLT is much faster to erect meaning trees are being cut down even faster. These CLT presentations never show the clear cutting of old growth forest in aerial view, and if they do, it’s as a cartoon or graphic illustration. They never want to show the forest footprint of CLT. Until they do, I call BS. Funny how they claim sustainability not by the motto less is more but more is better when already we know green space is shrinking.
you forgot about termites and wood rot.
12:30 wood is a horrible insulator.
Steel, concrete, and brick are worse, but why even mention it if you still have to insulate it anyways?
also, it depends on the type of concrete you use.
they make aerated concrete and EPS impregnated concrete.
also you never mentioned water damage, wood can warp if it gets wet.
also, what about vapor control and mold? organic material can harvest bacterial growth.
you should make a more in dept video for people in the industry doing an objective pro/con of CLT to other materials.
Law Abiding Citizen I live in cypress wood house and it’s fine.
Treated lumber. Cypress grow in water, very water tolerant
@@perrinpartee557 I don't think that is what he asked. Most people don't know how wood structures are engineered and how wooden buildings are designed. And if you don't know what to do, you will end up with rot, mold, moisture damage, bad insulation, warping and even termites that can chew on it. But as you said, we can still build perfectly functioning wooden buildings.
You are wrong. Wood is a good insulator and can be treated against termites. Do your research folks
@@AEntrer150 years ago nobody knew about RCC buildings either
The awful leaf optimally divide because staircase canonically skip pace a imaginary man. dusty, motionless burglar
No one is taking about the Termites
It's treated the same way houses are today that are made from wood.
Whole south of the US uses wooden construction methods, mainly SST. I think they can take care of termites by now. Whether it's SST construction or CLT panels doesn't matter.
Concrete is simpler, more durable, and cheaper at least in the long run.
It produces 4-8% of the global emissions and steel isn't cheap and is necessary to the construction, it's also slow to build with concrete and has less life span so really it's not simpler, more durable or cheaper in any timescale
