Interesting post on new French house building/renovation energy standards in another thread:

Rt2020 - ever heard of it?

So we’ve put in an offer on a building plot in Correze. I want to build something that basically requires no energy for heating, has a compost toilet, rain water harvesting. I’ve been reading up on passivhaus standards and I like the general idea but I’m put off by the software (not because I don’t like computers, more because I know programming and can see how error prone their software is) so then I looked at Canadian housing energy software, which includes value for money calculations which suits me much better.
