Stephane Bilodeau's insight:

Parmi les projets présentés, certains tentent de redonner un coup de vert à la ville. C’est le cas du "Cloud Corridor", imaginé par Ma Yansong du cabinet Mad Architects.

Ces neufs tours gigantesques s’inscrivent, selon leur auteur, dans la philosophie chinoise shan-shui. Un concept qui vise à réunir l’homme et la nature. Leur grande taille les assimile aux montagnes. On retrouve, sur différents étages, de larges espaces verts et les toits sont tous végétalisés. Qui plus est, les neufs bâtiments sont interconnectés par des ponts paysagers. Pour Ma Yansong, c’est à l’immobilier résidentiel de venir mettre en valeur l’environnement dans la ville, d’où ces minis villages verticaux

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.

Bubba Muntzer's comment, May 13, 2013 11:44 AM
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.

Aujourd'hui, la ville du futur c'est une cité qui s'articule autour de deux besoins : nature et communication. La mégapole de demain sera résolument verte, dotée d'un réseau de transports ultra performant et capable de communiquer avec le monde entier.

A Heat Exchanger is Transformed into a Contemporary Cultural + Sports Center

A Heat Exchanger is Transformed into a Contemporary Cultural + Sports Center | Développement durable et efficacité énergétique | Scoop.it

The transformation of this heat exchanger into a culture and sports center by slovakian firm atrium studio was part of a project for the EHMK 2013.

The angular exterior form extends the building out into the public space, with a dramatic climbing wall feature. The exchanger center has five different interconnected floors that have all been turned into gallery spaces - each fulfilling a different function. a secluded rooftop consists of four trees and a large lounge area.

The structure stands out within its surrounding context of industrial-type buildings, with the existing heat exchanger wrapped with a bold geometric facade. The folded triangular shapes define the building's exterior- cut out pieces of the twisted volume expose slanted view shafts of the interior windows, helping to express the new transformation.

That is a wild looking building. Technology and builders have come a long way in the way of designing.

Pittsburgh's "breathing" building by Gensler aims to be the world's greenest skyscraper

Pittsburgh's "breathing" building by Gensler aims to be the world's greenest skyscraper | Développement durable et efficacité énergétique | Scoop.it

The PNC Financial Services Group hopes to exceed LEED Platinum requirements while promoting a healthy workplace with a recent development – the Tower at PNC Plaza. Located in downtown Pittsburgh, the building will be 800,00 sq.ft (74,322 sq.mt) with a construction budget of approximately US $240 million.


The "breathing" design created by architecture firm Gensler moves away from the traditional closed air-conditioned environment and has the lofty aim of becoming the greenest skyscraper in the world.


Employees in the 33 floor glass tower will access daylight and fresh air. The PNC Tower design recognizes that the Pittsburgh climate can provide increased levels of natural light onto the floorspace along with improved regulation of temperatures for much of the year without using traditional, energy-intensive HVAC systems. The Tower hopes to achieve this with a double-skin facade of two panes of glass separated by an enclosed cavity, allowing external air inside. The facade features operable doors and windows that admit fresh air into the building during optimal conditions, while a solar chimney is another passive system- it pulls air in through the open windows, the air then travels across the floors, is heated and exhaled through the roof shaft.


The Tower will consume less than 50 percent of the energy a typical office building uses and will save PNC at least 30 percent on its energy costs...

Tall buildings have been historically less efficient than smaller squarer buildings to operate, but now with new technologies we are seeing rapid improvements in the taller buildings and FINALLY we are seeing things like operable ventilation once again.
