Thanks, curiosity. I saw Michael Reynolds speak last night, and found it amazingly motivating.

I have just bought a very environmentally unfriendly 50s weatherboard house, and am trying to find ways to make it more sustainable. At the moment it loses so much heat out of ceiling to floor single glazed windows, and it has no thermal mass to speak of. I'm toying with the idea of a tyre wall through the middle of it, but it's not a particularly practical solution.

But he made the point last night that every existing house has potential to be made more sustainable. You just have to think outside the square and come up with innovative solutions

Thanks for your links, I'll have a look.
