If you are interested to have a look at what can be done to make your house enjoyable and healthy to live in using natural heating and cooling systems, re-using greywater and water friendly gardens then make sure you visit a few houses in your area.
Details of the houses and locations can be found here.

And those Tasmanians have the best of it - a bus ride visiting 6 houses and it includes lunch.
