It's interesting. It all comes down to.... A lot of the renovations I'm talking about are buildings where the homeowner actually wants to tear the place down. Then they go to the municipality, and the municipality says, “Oh, no. You can't tear that old building down. You have to leave the foundation. You have to leave a wall.”
There's just no way to get that building to the point it needs to be with the foundation dug without any insulation. We're putting foundations in the ground with absolutely no insulation on the outside, little to no insulation on the slab. Those are things that can't be replaced.
I know it's not a popular opinion, but it just depends on the standard that you're trying to get to. If you're trying to get to this net zero standard, no, we can't get there by renovating those places. If you're just trying to reduce the standard, then, yes, there are things that can be done.
