The seemingly radical idea of building a skyscraper out of wood is not so strange after all, as architect Michael Green is quick to point out, because of two main advantages wood has over concrete and steel-it's eco-friendly and cost effective. Here's more on Vancouver's Tallwood project:
‘Tallwood’ would be made of large panels of ‘laminated strand lumber’—a composite made by gluing together strands of wood.
Trees are a renewable resource, and they help to reduce air pollution. Sourcing from sustainably-managed forests could be deemed more environmentally sensitive, according to CNN.
Unlike concrete—which produces about 6-9kg of carbon dioxide for every 10kg of concrete—wood sucks carbon out of the atmosphere.
And contrary to popular belief, wood actually is quite fire-resistant.
“It may sound counter-intuitive, but performing well in a fire is something inherent in large pieces of wood, that’s why in forest fires the trees that survive are the largest ones,” Green said.
I don't know why, but the preliminary photos of this project remind me of the tabletop game Jenga...
