Wood builds deliver climate change positives
Wednesday 12 Jun 2019
By using timber in our buildings, not only do we side-step emissions from carbon intensive materials, we also lock up carbon in the timber fabric of the building - a double whammy for attacking global warming.
We need to see our buildings as carbon banks where we can store the carbon absorbed by trees for decades into the future, if not in perpetuity. We need to have a "wood first" approach to building where you have to have a very good reason for not using timber beams, columns, floors, claddings and linings in our commercial buildings as well as our houses.
Weight for weight engineered timber is about as strong as steel, and while we need bulkier timber members for equivalent functions, we can design for that. Perhaps surprisingly, heavy timber columns and beams can perform well in fires, thanks to the charring process on the outside which protects the interior structural timber.
