I apologize if I've read too much into your comments, but I think you're the one making estimates replacing everyone's housing? It's certainly not something I'm suggesting.
- philwelch 8y agoI was replying to Tharkun's comment that upgrading housing to PassivHaus standards could "solve" the problem of generating energy for heating. It does no such thing unless you actually upgrade the housing, and there's a lot of housing in the world.
- Tharkun 8y agoDepending on where you are and what your house is like, it could be feasible and financially viable to retrofit your house. In other places (Japan comes to mind), houses have a relatively short shelf-life. Making passive the default could have a big impact there. And in many urbanized areas, there is a housing shortage. This can lead to ridiculous price increases, or to a housing boom. Again, building new developments to passive standards could make a big dent. I would love a magic wand to make every house passive, but I'm sadly aware that it's unlikely to happen. In many cases, the economics make sense.
