(Norris, WBIR) - State environmental officials toured one of Tennessee's most energy-efficient homes on Thursday.
The New Norris House, which is owned by the University of Tennessee, was recently named one of the nation's top 10 examples of sustainable architecture and green design.
They discussed water conservation measures and treatment technologies.
The home collects rainwater on the roof, treats it, and then uses it for 30 percent of water use in a two-person home.
"We want to separate people from their waste water, and we've been doing a good job of that. But if we can be more sustainable by putting water back in the landscape so it can recharge the ground water and not focus so much water at a point discharge or waste water treatment plant, then it's much more sustainable. Much more doable over the long term," said Associate Professor John Buchanan.
Researchers say what they're doing here on a small-scale at one house could have bigger implications if a whole community implemented it.
