Concrete Vs Wood
Our friend Eric sent us an article in the Globe and Mail yesterday about plans to build a 35 to 40 story tower in Vancouver out of wood. Here’s the link to that story but you can’t read it without a subscription.
Contrast that to the dominant way we build tall buildings in NYC which is out of concrete, steel, and glass.
The reason that a move back to wood based structures is so important is that the concrete structures are huge contributors to greenhouse gases. According to the Globe and Mail article, “concrete construction is responsible for an estimated eight per cent of all carbon emissions worldwide.”
The Gotham Gal and I are in the process of making two passive house apartment buildings in Brooklyn based on cross-laminated timber structures with only a small amount of concrete in them.
This is a photo of one of them back in December when the CLT structure had just been completed:
Our buildings are five or six stories high. The idea that you can make a building of 35 or 40 stories out of CLT and dowel laminated timbers (DLT) is very exciting to me.
I believe we can innovate our way out of the climate change mess we are in right now and changing the way we make our homes and offices is a big part of that.
