That's interesting. I'd be curious to read how it breaks down. I remember chatting to someone about commercial buildings in the city and what amazed by how much of a demolished building is now recycled. I wonder if that depends on commercial vs resi, or even a subset of different types of commercial buildings.
But yeah my main thought would be that leaving buildings in situ and adapting them is the ideal.
In reference to building elements -

If we're talking whole buildings - the longer you can keep a building in use through adaptive reuse, the more value you get out of the initial resource extraction, embodied carbon emissions etc.
