That's all well and good, but new buildings need to have this designed in from the outset. If you can have a passiv haus in Sweden it will work anywhere.
Retrofitting these buildings is really important though. We can't just have loads of new housing stock overnight. My flat's in an old (1800 and something) building and it's pretty leaky wrt heating and there's no insulation, just thick stone walls. Even houses built in the 80's have no insulation, or minimal 50mm rockwool where now 250mm is recommended and the performance is higher. The way buildings are built wrt to environment and landscape is important too to make them more sustainable.
