And then, there is Portland cement concrete. Of course it needs steel reinforcing but it is superior to wood both structurally and architecturally.
I would think a proper use of Green wood would be to make the frames and support structures for wind turbine towers and solar collector arrays. That however is not done. There are no such structures made from wood composites.
They reason concrete is used is because it is CHEAP and it has good compression strength when cured. It is also very heavy. Why not just build all our multistory buildings out of granite? It has good compression strength, is pretty and will last for 3000 years.
On the other hand. Lets build all our buildings out of graphite, titanium and Kevlar. I am sure a Kevlar building would be much stronger than steel, concrete or cellulose based materials.
