It
mostly doesn't matter.
If the building burns down, and you build a new one, you're still at the same net amount of CO2 in the atmosphere at the end of the day, just with a little lag while the trees that got cut down to build the building grow back.
Also, it's a pretty apocalyptic world if most buildings burn down haha. There are extremely old wood buildings in the world, no reason they can't last. Most buildings that get torn down end up in the dump. We could also recycle the wood to some extent, but let's assume they all get dumped. In anaerobic conditions, ~90% of the wood will still be there in 50 years. So most of it is still sequestered carbon in the dump.
