Wooden Skyscrapers: A New Level of Sustainability?

Wooden Skyscrapers: A New Level of Sustainability? | Développement durable et efficacité énergétique | Scoop.it

A new breed of high-rise architecture is in the process of being born, thanks to the collaborative efforts of modern design pioneers. Envisioned as the best sustainable option for meeting world housing demands and decreasing global carbon emissions, wooden mega-structures are now one step closer to becoming a reality.


“Big Wood,” a conceptual project to the eVolo 2013 Skyscraper Competition, builds on the premise that wood, when harvested responsibly, is one of the best tools architects and engineers have for reducing greenhouse gas emissions and creating healthy communities. Aspiring to become one of the greenest skyscrapers in the world, Big Wood challenges the way we build our cities and promotes timber as a reliable platform to support tomorrow’s office and residential towers...

The Case For Tall Wood                               Michael Green Architecture

I find this hard to truly picture, but the story is solid...."the last century there has been no reason to challenge steel and concrete as the essential structural materials of large buildings. Climate change now demands that we do.....Wood is the most significant building material we use today that is grown by the sun. When harvested responsibly, wood is arguably one of the best tools architects and engineers have for reducing greenhouse gas emissions and storing carbon in our buildings."

 

“I’d put my money on solar energy…I hope we don’t have to wait till oil and coal run out before we tackle that.”
~Thomas Edison, In conversation with Henry Ford and Harvey Firestone March 1931

“Known as the birthplace of the skyscraper, Chicago is an optimal location for a prototype in mass timber construction,” writes Carlos Arzate

Fascinating place. Must of been a lot of wood to be created.

It takes around 30 years for a seedling to grow into the kind of wood that can be used in construction. A little maintenance is required during that period. Meanwhile it's soaking up CO2 and making oxygen. The only industrial processes required are to cut it down and cut it into boards and 2 x 4s. If you stagger your planting you have an endless supply.

Magnetoelectrics could advance computer memory, ending reliance on 1s and 0s

Magnetoelectrics could advance computer memory, ending reliance on 1s and 0s | Développement durable et efficacité énergétique | Scoop.it

Generally, hardware upgrades incrementally — processors slowly gain more cores, graphics cards slowly become more powerful, and storage devices slowly gain more capacity. Hardware rarely upgrades with a significant leap, jumping from one form to another that is so significantly upgraded that it barely resembles what came before it. These leaps do happen though — in just a matter of a few years dumbphones evolved into smartphones and a great deal of laptops become super slim tablets. Now, utilizing a new type of magnetoelectric material, computer memory may take that significant leap.
