Just read an interesting article on Smart Planet titled “Greenest building in world uses no water or electricity”
It’s a pretty cool building – looks like it’s offices and residential apartments. It has solar panels all over it that provide the electricity for the building and also to power the ground source heat pump (GSHP) that is underneath. All the water that falls on the building is collected and filtered to be used inside.
I must admit, that reading it I felt like we’re not far off with our house. All of the water that falls on our roof is collected into a 5000 litre tank and is routed to the toilets, washing machine and outside taps. We’re not drinking it because I didn’t find a domestic solution that gave me comfort that it would be safe. I’m hoping to get solar panels installed which should provide enough electricity to power the GSHP and contribute to our electricity generally.
