> He’s s still evaluating bottom-line costs. Four days to assemble, how many days did it take to build, in China? What about the energy loss in transport? How much carbon was generated by this project versus if it had been built with modernist techniques. More interesting if had been been built with pre 20th century techniques.

Depends if they were shipping complete panels with infill, hollow panels, or just precut frame parts, but in all cases it should still be economical to bring stuff across the pacific.

  Good point, it would fare better in an earthquake. > Some 1,400 years ago, tall wood-framed pagodas in Japan were built to 19 stories tall. In spite of the area’s high seismic activity – including the 6.8 magnitude Hyogo-ken Nambu earthquake in 1995 that caused widespread damage – these structures still stand today. https://csengineermag.com/article/wood-frame-construction-advantageous-in-areas-prone-to-seismic-activity/ https://csengineermag.com/article/wood-frame-construction-ad... Now, I don't know if actually would fare better than a steel frame in an earthquake (which this building is very close a fault line), but the Japanese seemed to have figured out how to do it a long time ago. I don't know because I am not even close to experienced with wood structures over 3 stories.

    In japan they build pre fabricated building for years, made from steel or concrete slabs. Those building are pretty solid but in Japan they tend to destroy them after a while and build new ones instead anyway.

Awesome video. That's as pretty as a ballet to me. I've built a 14x9 meter 3 story high workshop attached to a house with a very small crew and I can totally relate to all the work that is being done there. That is most likely not the first barn that crew put together.

I feel like you may want to go a little further back than the 20th century. There is a large time span in there that was the single most dirty and unhealthy time in human history which started off our incredible production of carbon and subsequent impact on climate change.

Days to assemble in China is not as long as you would think. Probably less than a month to build if I had to guess. Once you establish the first prototype others don't take as long. Most of the time went into R&D. It really depends how far back you want to go with sourcing material components. You arent going to make your own steel beams from pigiron. Energy loss in transport can be calculated by the amount of containers needed overseas for building construction materials. I would guess about 3 or 4 , 45' or 53' high cube containers in raw materials. I could not find good estimates on volume of materials needed for this type of building right away. Carbon footprint is probably not as crazy as you would assume. Many parts are sourced overseas and end up in home depot etc. Adding logistics warehouse and labor to manage this adds significantly higher carbon footprint overall than just a one time shipment.
