Net Zero Energy + LEED Platinum Luxury: Castaway III Home

Castaway III Net Zero Energy Luxury Home
The Castaway III home in Palm Harbor, Florida is a net zero energy showcase of extreme energy efficiency. It also happens to be an amazingly plush, luxurious home. Castaway III is the latest creation from Florida developer Marc Rutenberg, and it’s the model for his proposed Zero Energy America Village housing development.

Open to the public, the 4,552 square-foot Castaway III incorporates features 4 bedrooms, a den, 3 bathrooms, a gameroom, and a 3-car garage, plus a host of cutting-edge technologies to achieve its extreme level of efficiency. And while the home is valued at over a million dollars, Rutenberg calls the Castaway III a net zero energy “laboratory” to demonstrate that energy-efficient luxury can be affordable on a large scale (comparably efficient future homes are expected to start around $250,000).
