As we saw in the great presentation by architect Michael Green, tall wooden buildings have a great story to tell from the carbon footprint standpoint. Green's firm has produced a document that makes this case most throughly: Tall Wood: The Case for Tall Wood Buildings.
The project owners tell it quite simply by comparing the value of the project relative to removal of cars from the road:
"By using CLT, Lend Lease claims, the project, Forté, will reduce CO2 equivalent emissions by more than 1,400 tonnes when compared to concrete and steel – the equivalent of removing 345 cars from our roads."Whether one believes in anthropogenic (man-caused) global warming or not, it would seem that any certain simple choice of building materials that would have the net impact, from an emissions standpoint, of permanently removing 345 cars from the road would be a good one. Imagine that same decision being made hundreds, thousands, tens of thousands times over. The thought of that has caused one architect to call Cross-Laminted Timber "the concrete of the 21st century", as you'll hear in the following short video...
I think this is a story, and a trend, that has legs. Time will tell. This is one project I would love to visit for its grand opening this fall. Melbourne, anyone?
