Gallery: Michael Green Unveils ‘Tall Wood’ Tower for Vancouver Along Wi...

 

A wooden skyscraper may seem like far-fetched idea to those who live in cities built from concrete and steel, but architect Michael Green has developed an innovative wooden tower for Vancouver that could spark a renaissance in using wood to build urban high-rise projects. If realized, Green’s Tallwood tower could be one of the greenest skyscrapers in the world – and at 30 stories, perhaps the tallest of its kind. Best of all, Green has documented his research and design specifications and generously published the results in an open source paper – a kind of instruction manual for building really tall wood buildings.

    supreb thouht by sirM.green…m a kinda big fan of him abut his work in the field of architecture..he has given a new generation to the ffiel of architecture explaining about the timber

    @Observer
    “Trees chopped down” – this is a common misconception with sustainable forestry. When trees are cut down they are replanted in great abundance. This isn’t deforestation, but maintaining a renewable natural resource.

    A better question is “How much hydrofracking is required to obtain enough natural gas to make a concrete and steel building.” I am not sure, but the answer is a lot . . . how much natural gas for LVL structure . . . zero.

    I don´t understand why would it be the greenest building. How many trees will have to be chopped down to supply timber? You will need good dried wood for this despite LVL.
    “The wooden tower may seem like a fire hazard, but in reality it is actually safer than steel.” Mmmmm. Do you have any example of steel framed buildings that collapsed due to fire at 650º Celsius?

    @Andy,

    Steel loses strength very quickly in a fire where wood does not http://www.gsegroup.com/html/modules.php?op=modload&name=News&file=article&sid=152&popup=1&newlang=eng.

    Yes wood burns, but the larger it is the slower it loses integrity, a predicable effect engineers can design for when making fire rated assemblies.

    “The wooden tower may seem like a fire hazard, but in reality it is actually safer than steel. When exposed to fire, large timbers develop a charred exterior that insulates the structural wood underneath. In fact, the weakest point in a fire is the steel connection from the beams to the supporting posts.”

    Uh huh… Would you like I send you pictures of various all wood structures of the ‘post and beam’ type that used just this very sort of wooden beam? I can send ‘before and after’. After, typically, is a large hodge podge of burned wood and no identifiable structure.

    The reason, I think, that the ‘weakest point’ exists is that steel (pretty much non combustible) is attached one way or another to wood (very combustible). Am I surprised when the wood burns/weakens that the steel ‘connector’ loses its connection. Not a bit.
